Definitions
- the present disclosure generally relates to ammunition reloading, and more particularly to a primer pocket swager for swaging primer pockets in ammunition cases.
- Centerfire ammunition cartridges generally include a case, a bullet seated in a mouth of the case, a propellant inside the case, and a primer seated in the primer pocket of the case for igniting the propellant.
- the primer pocket is crimped to secure the primer in the primer pocket. The crimp is usually made by deforming a side wall of the primer pocket inward to protrude against the primer. After such a cartridge is fired, if it is desired to reload the case, the primer pocket usually needs to be swaged to prepare the primer pocket for receipt of a new primer. Sometimes uncrimped cases are swaged to properly size the primer pockets.
- Various devices are known for swaging primer pockets.
- a swaging pin is pushed into the primer pocket.
- a head of the swaging pin is sized to expand the crimped portion of the primer pocket to provide the primer pocket with a relatively smooth side wall. Insertion of the new primer is then much easier and reloading results are improved.
- a primer pocket swager is for swaging a primer pocket of an ammunition case.
- the primer pocket swager includes and a case holder.
- the case holder is supported by the frame and is movable with respect to the frame between a loading position and an operational position.
- the case holder in the loading position being oriented to receive the case on the case holder.
- the case holder in the operational position being oriented to hold the case in position to be swaged.
- the case holder being configured to carry the case from the loading position to the operational position.
- the primer pocket swager includes a swage head supported by the frame. The swage head is sized and shaped to swage the primer pocket of the case.
- the swage head is movable between a retracted position and a swaging position to swage the primer pocket when the case holder is in the operational position.
- the primer pocket swager includes an actuator supported by the frame. The actuator is movable with respect to the frame in an actuating stroke from a home position to an actuated position. The actuator is operatively connected to the case holder such that the actuator drives the case holder to the operational position in the actuating stroke. The actuator is operatively connected to the swage head such that the actuator drives the swage head to the swaging position to swage the primer pocket
- a primer pocket swager in another aspect, includes a frame and a case holder supported by the frame.
- the case holder is configured to hold the case in position to be swaged.
- a swage shaft is supported by the frame.
- the swage shaft has a first swage head located at a first end of the swage shaft and a second swage head smaller than the first swage head located at a second end of the swage shaft opposite the first end.
- the swage shaft is movable from a retracted position to a swaging position. At least one of the first and second swage heads is oriented to swage the primer pocket when the swage shaft is in the swaging position.
- An actuator is supported by the frame and movable with respect to the frame in an actuating stroke from a home position toward an actuated position.
- the actuator is operatively connected to the first swage head such that movement of the actuator in the actuating stroke drives the swage shaft toward the swaging position to swage the primer pocket.
- a primer pocket swager in yet another aspect, includes a frame and a pivot mount supported by and pivotable with respect to the frame.
- a case holder is secured to the pivot mount and is configured to hold the case in position to be swaged.
- the pivot mount has a track.
- a pivot mount guide includes a follower biased against the pivot mount. The follower is configured to ride the track on the pivot mount during pivoting of the pivot mount.

- an ammunition case primer pocket swager is designated generally by the reference number 10 .
- the swager 10 is configured to swage primer pockets of ammunition cases C ( FIG. 4 ) to prepare the primer pockets for installation of new primers.
- the swager 10 can be used to conveniently and efficiently swage primer pockets of a plurality of cases C in a relatively short amount of time.
- Components of the swager can be made of metal and/or plastic or any other suitable material.
- the swager 10 includes a frame 12 , an actuator 14 , a case holder 16 , and a swage shaft 18 .
- a user installs a case C on the case holder 16 and then actuates the actuator 14 .
- Movement of the actuator 14 in an actuating stroke causes the case holder 16 to move from a loading position (e.g., FIG. 4 ) to an operational position (e.g., FIGS. 5, 6 ) to locate the case C for swaging.
- Movement of the actuator in the actuating stroke also causes the swage shaft 18 to move downward to a swaging position (e.g., FIG. 6 ) swage the primer pocket.
- the swager 10 is configured to precisely position and orient the case C to achieve optimal and consistent swaging.
- the swage shaft 18 moves upward, and the case holder 16 moves from the operational position back to the loading position.
- the case holder 16 presents the swaged case C to the user for convenient unloading of the case and installation of another case to be swaged.
- the frame 12 is provided in the form of an upstanding housing.
- the housing 12 can be formed of cast metal.
- the housing 12 supports the other components of the swager 10 .
- the housing 12 includes a base and a superstructure extending upward from the base.
- the base defines a bottom 12 A of the housing that is configured to rest on a surface such as a table top or other suitable surface.
- the base includes left, right, and rear wings 12 B having respective fastener mounts 20 in the form of circular openings. For example, bolts, screws, or other fasteners (not shown) can be installed in the openings 20 to anchor the base to a suitable surface.
- the body includes a front wall 12 C, left side wall 12 D, and right side wall 12 E, and an open rear exposing an interior of the housing.
- the front wall 12 C defines a case receiving recess 12 F into which the case holder 16 is movable to the operational position to carry a case C into position to be swaged.
- the actuator 14 and case holder 16 protrude forward in front of the front wall 12 C, and several other components of the swager 10 are housed in the interior of the housing behind the front wall.
- the actuator 14 is provided in the form of a lever.
- the lever 14 includes a proximal end adjacent the housing 12 and a distal or free end spaced from the proximal end.
- the proximal end is secured to an upper pivot mount 24 at an upper end of the housing 12 .
- the pivot mount 24 is pivotally connected to the housing 12 by a pin 26 and configured to pivot about a generally horizontal lever pivot axis LA defined by the pin 26 .
- the proximal end of the lever 14 has a threaded bore and is received in a first side of the pivot mount 24 .
- the lever 14 is secured to the pivot mount by a bolt 28 in the pivot mount 24 forming a threaded connection with the threaded bore of the lever.
- the lever 14 is shown in a home position in FIGS. 1-4 . In the home position, the lever 14 extends forward and upward. The lever 14 is pivotable downward in an actuating stroke from the home position to an intermediate position (e.g., FIG. 5 ) and further to an actuated position (e.g., FIG. 6 ). The actuated position can vary based on the type of case C being swaged and the adjustment of various components of the swager 10 . In the actuated position, the lever 14 extends forward. The arrangement is such that a user can grip the lever 14 in the home position by hand and conveniently pull downward to actuate the swager 10 by moving the lever from the home position to the actuated position. The lever 14 is movable in a return stroke from the actuated position back to the home position. Other types of actuators can be used without departing from the scope of the present invention.
- the case holder 16 includes a shaft having a threaded proximal portion 16 A and a distal portion 16 B.
- the distal portion is sized to receive a case C to be swaged by placing the mouth of the case over a tip of the distal portion 16 B and sliding the case downward.
- the threaded portion 16 A is secured to a lower pivot mount 30 having opposite ends received in openings 32 in the sides of the housing 12 pivotally connecting the lower pivot mount to the housing.
- the lower pivot mount 30 defines a pivot axis CA about which the lower pivot mount and the case holder 16 are conjointly pivotable.
- the case holder 16 is pivotable about the pivot axis CA between a loading position (e.g., FIGS.
- the threaded portion 16 A of the case holder 16 is threaded into a threaded opening in the lower pivot mount 30 .
- An O-ring 34 of resiliently compressible material is carried in a circumferential groove in the threaded portion 16 A to create friction in the threaded opening of the pivot mount 30 to avoid rotation of the case holder 16 and maintain it in a desired position with respect to the pivot mount.
- the case holder 16 can be threaded into or out of the pivot mount 30 to set a depth to which the case's primer pocket will be swaged by the swage shaft 18 . As shown in FIG.
- case holder 16 when the case holder 16 is in the loading position, the case holder extends forward and upward and out of the case receiving recess 12 F at an angle with respect to vertical. In the loading position, the case holder 16 is oriented to permit a user to conveniently access the distal portion 16 B to load cases onto and unload cases from the case holder.
- the case holder 16 is pivotable to the operational position by actuation of the lever 14 to carry the case C into positon to be swaged.
- Other types of case holders can be used without departing from the scope of the present invention.
- the swager includes a drive linkage, generally indicated at 40 , operationally connecting the lever 14 to the case holder 16 and operationally connecting the lever to the swage shaft 18 for driving movement of the case holder and swage shaft in a sequenced manner.
- the drive linkage 40 is located behind the front wall 12 C and housed mostly in the interior of the housing 12 .
- the drive linkage 40 includes a first drive train 40 A operationally connecting the lever 14 to the case holder 16 and a second drive train 40 B operationally connecting the lever to the swage shaft 18 .
- Both the first and second drive trains 40 A, 40 B include the upper pivot mount 24 from which the lever 14 extends.
- the first and second drive trains 40 A, 40 B branch from the upper pivot mount 24 downward toward the respective case holder 16 and swage shaft 18 .
- the first drive train 40 A further includes a first link 42 , a second link 44 , and a third link 46 .
- the first drive train 40 A also includes the lower pivot mount 30 .
- the first link 42 is an extendable link (broadly, “lost motion link”) and is provided in the form of an extension spring.
- the extension spring 42 includes an upper arm 42 A, an intermediate coil portion 42 B, and a lower arm 42 C.
- the extension spring 42 can be formed of a continuous piece of wire.
- the upper arm 42 A includes a hook pivotally connecting the extension spring 42 to an eye bolt 48 threaded into the upper pivot mount 24 .
- the intermediate coil portion 42 B defines a helical winding having several turns.
- the lower arm 42 C includes a hook pivotally connecting the extension spring to the second link 44 .
- the extension spring 42 is extendable from a retracted configuration (e.g., FIGS. 4, 5 ) to an extended configuration (e.g., FIG. 6 ) to create lost motion between the lever 14 and the case holder 16 when the case holder is in the operational position.
- consecutive turns of the helical winding 42 B engage and rest against each other.
- the helical winding 42 B is extended such that the consecutive turns of the helical winding are spaced from each other.
- a forward end portion of the second link 44 is pivotally connected to the extension spring 42 .
- the second link 44 is pivotally connected to the housing 12 by a pin or jack shaft 50 received in openings in the left and right side walls 12 D, 12 E of the housing 12 .
- the second link 44 is pivotable about a jack shaft pivot axis JA extending along the length of the jack shaft 50 .
- the third link 46 is provided in the form of two elongate bars (each indicated at 46 ) having upper ends on opposite sides of and pivotally connected to the rear end portion of the second link 44 by a pin 52 .
- the two elongate bars 46 have lower ends pivotally connected by a pin 54 to an eye bolt 56 extending from the lower pivot mount 30 .
- the eye bolt 56 is threaded into and conjointly pivotable with the lower pivot mount 30 like the eye bolt 48 is threaded into and conjointly pivotable with the upper pivot mount 24 .
- the arrangement is such that pivoting of the lever 14 in the actuating stroke from the home position toward the actuated position causes the upper pivot mount 24 to rotate clockwise, which pulls the spring 42 , creating tension force in the spring but not extending the spring, and causes the second link 44 to rotate counterclockwise about the jack shaft axis JA.
- the second link 44 pushes the third link 46 , creating compression force in the third link between its pin connections, which causes the lower pivot mount 30 to rotate counterclockwise to move the case holder 16 from the loading position toward the operational position.
- the clockwise rotation of the upper pivot mount 24 is converted by the first drive train 40 A to counterclockwise rotation of the lower pivot mount 30 .
- the first link 42 is in its retracted configuration and does not begin extending until the case holder 16 reaches the operational position.
- the case holder 16 reaches the operational position when the lever 14 reaches an intermediate position (e.g., FIG. 5 ) in the actuating stroke between the home and actuated positions.
- the extension of the spring 42 permits further pivoting of the lever 14 in the actuating stroke beyond the intermediate position to the actuated position so the second drive train 40 B can drive the swage shaft 18 to swage the primer pocket while the first drive train 40 A maintains the case holder 16 in the operational position.
- the first drive train 40 A includes seven pivot connections.
- Three of the pivot connections are pin connections of the drive train 40 A with the housing 12 .
- the upper pivot mount 24 is pivotally connected to the housing 12
- the jack shaft 50 pivotally connects the second link 44 to the housing
- the lower pivot mount 30 is pivotally connected to the housing.
- three of the pivot connections are fixed with respect to the housing 12 .
- the other four pivot connections are movable with respect to the housing 12 responsive to movement of the lever 14 .
- these include the pivot connections at the opposite ends of the spring 42 , and the pivot connections at the opposite ends of the third link 46 .
- the second drive train 40 B includes the upper pivot mount 24 , a link 60 , and a ram 62 .
- the link 60 includes an upper end pivotally connected to the upper pivot mount 24 by a pin 64 .
- a lower end of the link 60 is pivotally connected to the ram 62 by a pin 66 .
- the ram 62 is received in a guide 12 G defined by the housing 12 .
- the ram 62 includes a lower sleeve 62 A having a bore sized for receipt of the swage shaft 18 .
- the swage shaft extends downward below the ram 62 .
- a compression spring 68 surrounding the ram 62 has an upper end engaging an upper portion of the ram and has a lower end engaging an upper portion of the guide 12 G.
- the compression spring 68 biases the ram 62 upward and is compressible to permit downward movement of the ram.
- the arrangement of the second drive train 40 B is such that movement of the lever 14 in the actuating stroke from the home position toward the actuated position causes clockwise rotation of the upper pivot mount 24 , which pushes on the link 60 , creating compression force between its pin connections.
- the link 60 pushes the ram 62 and thus the swage shaft 18 downward for swaging the primer pocket of the case C.
- the second drive train 40 B converts the rotational movement of the upper pivot mount 24 to translational or sliding movement of the ram 62 to move the swage shaft 18 between a retracted position (e.g., FIG. 4 ) and a swaging position (e.g., FIG. 6 ).
- the second drive train 40 B initially moves the swage shaft 18 downward while the first drive train 40 A moves the case holder 16 to the operational position.
- the second drive train 40 B continues to move the swage shaft 18 downward after the first drive train 40 A moves the case holder 16 to the operational position and while the first drive train maintains the case holder in the operational position.
- the pivot connection of the second drive train link 60 to the upper pivot mount 24 moves “over center” with respect to the pivot axis LA of the upper pivot mount to provide mechanical advantage in swaging the primer pocket and provide a reduction of pressure felt by the user in moving the lever downward.
- the pivot axis defined by the pin 64 approaches and/or crosses a line extending between the pivot axis LA defined by the pin 26 and the pivot axis defined by the pin 66 .
- the second drive train 40 B includes three pivot connections.
- One of the pivot connections is a pin connection of the upper pivot mount 24 with the housing 12 . This pivot connection is fixed with respect to the housing 12 .
- the other two pivot connections i.e., the pivot connections at the opposite ends of the link 60 , are movable with respect to the housing 12 response to movement of the lever 14 .
- the ram spring 68 biasing the ram 62 upward with respect to the ram guide 12 G also biases the lever 14 toward and maintains the lever in its home position and biases the case holder 16 toward and maintains the case holder in its loading position.
- the lever is biased upward by the ram spring 68 via the second drive train 40 B.
- the spring 68 pushes upward on the ram 62 , which pushes upward on the link 60 and tends to rotate the upper pivot mount 24 counterclockwise. This in turn, via the first drive train 40 A, tends to rotate the lower pivot mount 30 clockwise.
- the lever 14 is located in its home position, and the case holder 16 is located in its loading position, by engagement of a side of the second drive train link 60 with a flat 24 A on the upper pivot mount 24 . It will be appreciated that if the spring 42 were not in its retracted configuration when the lever 14 is in the home position, tension in the spring 42 would tend to move the case holder 16 toward the operational position.
- the lost motion link may be configured to retract rather than to extend for providing the lost motion.
- other types of drive trains having other types of links are possible.
- the swager 10 includes several features that assist in properly aligning the case C with the swage shaft 18 for optimal and consistent swaging.
- the swager 10 includes a pivot mount rotation guide 70 , a case aligner 72 , and a case holder stop 74 .
- the pivot mount rotation guide 70 promotes the case holder 16 to move in an arcuate path that is coplanar with a swaging axis SA of the swage shaft 18 .
- the case aligner 72 and case holder stop 74 serve to align the primer pocket of the case C with the swaging axis SA of the swage shaft 18 .
- the pivot mount rotation guide 70 includes a ball bearing 70 A, a spring 70 B, and an actuator in the form of a set screw 70 C.
- the ball bearing 70 A, the spring 70 B, and the set screw 70 C are all received in an opening in the housing 12 adjacent the lower pivot mount 30 .
- the set screw 70 C is threaded in the opening and serves as an adjustable backing for the spring 70 B, which biases the ball bearing 70 A against the lower pivot mount 30 .
- the lower pivot mount 30 includes a circumferential arcuate slot 30 A facing the ball bearing 70 A.
- the arcuate slot 30 A is rectangular in section and has left and right arcuate edges at opposite sides of the slot extending circumferentially around the lower pivot mount 30 at its outer surface.
- the arcuate slot 30 A can be referred to as a track, and the ball bearing 70 A can be referred to as a follower on the track.
- the ball bearing 70 A rides on the left and right edges of the track 30 A.
- Pressure of the ball bearing 70 A against the track 30 A can be adjusted by threading the set screw 70 C toward or away from the lower pivot mount 30 .
- the arrangement is such that the pivot mount rotation guide 70 promotes rotation of the lower pivot mount 30 about the axis CA perpendicular to the swage shaft axis SA and thus promotes movement of the case holder 16 in an arcuate path coplanar with the swage shaft axis SA.
- the bias of the ball bearing 70 A against the lower pivot mount 30 “bottoms out” the opposite ends of the lower pivot mount 30 in forward ends of the openings 32 in housing 12 , to take out any looseness or slop of the pivot connection of the lower pivot mount and the housing. This promotes alignment of the case holder 16 left to right with respect to the swage shaft 18 when the case holder 16 is in the operational position.
- Case holder mounts having other configurations can be used without departing from the scope of the present invention.
- the pivot mount guide can have other configurations or be omitted.
- the case aligner 72 is provided in the form of a case pusher arranged to push against the case C when the case holder 16 is in the operational position.
- the case pusher 72 includes a plunger 72 A having a head 72 B defining a case engagement surface.
- the plunger 72 A is slidable in a plunger guide 12 H defined by the housing 12 and is biased forward by a spring 72 C.
- a fastener 72 D e.g., roll pin
- the arrangement is such that as the case holder 16 approaches the operational position (e.g., FIG.
- the plunger 72 A contacts the case C, and in response to movement of the case, the plunger moves rearward and compresses the spring 72 B.
- the force of the plunger 72 A on the case C causes the inside curved surface of the case side wall to abut the outer curved surface of the case holder 16 . This centers the case C left to right on the case holder 16 with respect to the housing 12 .
- Other types of case aligners can be used, or the case aligner can be omitted, without departing from the scope of the present invention.
- the case holder stop 74 is provided in the form of a thumb screw including a head or knob 74 A and a threaded shaft 74 B.
- the threaded shaft 74 B is received in a threaded opening in the lower end of the housing 12 .
- the shaft 74 B includes a distal end positioned to engage the case holder 16 to locate the case holder in its operational position. As shown in FIGS. 5 and 6 , the distal end of the shaft 74 B (broadly, “stop surface”) engages a portion of the case holder 16 protruding below the lower pivot mount 30 when the case holder is in the operational position.
- the first drive train 40 A is prevented from further rotating the lower pivot mount 30 , and further movement of the lever toward the actuated position causes extension of the spring 42 .
- the operational position of the case holder 16 can be precisely adjusted by threading the case holder stop 74 into or out of the housing 12 .
- a retainer 80 e.g., elastomeric pad or O-ring
- the case holder stop 74 permits precise front to back adjustment of the case holder 16 with respect to the swage shaft 18 . It will be appreciated that in the operational position, the longitudinal axis of the case holder 16 is not necessarily aligned with the longitudinal axis of the swage shaft 18 . As shown in FIGS. 5 and 6 , the longitudinal axis of the case holder 16 may point rearward such that the case C pushed forward on the case holder by the case aligner 72 has its primer pocket in alignment with the longitudinal axis of the swage shaft 18 .
- Other types of case holder stops can be used, or the case holder stop can be omitted, without departing from the scope of the present invention.
- the swager 10 can be configured to swage cases having different mouth sizes.
- the swager 10 can be provided with a set of interchangeable case holders 16 , 116 for use with cases having different mouth sizes.
- a set of two case holders 16 , 116 is provided.

- An O-ring 134 is carried by the threaded end portion 116 A to create friction at the threaded connection of the case holder 16 and the lower pivot mount 30 .
- the second case holder 116 has a larger diameter distal end portion 116 B and can be used for cases having relatively large case mouths.
- the swager 10 can be configured to swage cases C having different sizes of primer pockets.

- Each swage head 90 , 92 includes a generally cylindrical protrusion surrounded by an annular shoulder where the cylindrical protrusion connects to a main body of the shaft 18 .
- the swage shaft 18 is releasably secured to the ram 62 by a retainer 96 including a handle 96 A and a pin 96 B.
- the pin 96 B extends through aligned openings in the ram 62 and the swage shaft 18 .
- the retainer 96 is releasably maintained in the ram 62 by a ball detent 96 C ( FIG. 2 ) protruding laterally from a side of a distal end of the pin 96 B.
- a user can change which swage head 90 , 92 is positioned for use by pulling the handle 96 A of the retainer 96 rearward.
- the ball detent 96 C retracts into the pin 96 B of the retainer 96 , and the pin can be withdrawn from the ram 62 and swage shaft 18 .
- the swage shaft 18 can then be dropped down out of the ram 62 , and inverted and repositioned in the ram with the other swage head 92 pointing downward for swaging. Reinstallation of the retainer 96 secures the swage shaft 18 in this inverted configuration in the ram 62 .
- the swage head 90 , 92 may become lodged in a primer pocket such that the case C moves upward with the swage shaft 18 in the return stroke of the lever 14 .
- a replaceable extractor 98 is provided to engage the primer pocket end of the case C and permit the swage head 90 , 92 to be withdrawn from the primer pocket.
- the extractor 98 is releasably mounted on the housing 12 by receipt in a slot in the front of the housing.
- the swage shaft 18 extends through an opening in the extractor sized slightly larger than the swage shaft.
- a case C stuck on the swage head 90 , 92 would engage the extractor 98 to remove the case from the swage head and drop the case back onto the case holder 16 .
- the user selects which swage head 90 , 92 and case holder 16 , 116 are appropriate for a particular type of case C to be swaged.

Abstract
Description
- The present disclosure generally relates to ammunition reloading, and more particularly to a primer pocket swager for swaging primer pockets in ammunition cases.
- Centerfire ammunition cartridges generally include a case, a bullet seated in a mouth of the case, a propellant inside the case, and a primer seated in the primer pocket of the case for igniting the propellant. In some cartridges, the primer pocket is crimped to secure the primer in the primer pocket. The crimp is usually made by deforming a side wall of the primer pocket inward to protrude against the primer. After such a cartridge is fired, if it is desired to reload the case, the primer pocket usually needs to be swaged to prepare the primer pocket for receipt of a new primer. Sometimes uncrimped cases are swaged to properly size the primer pockets. Various devices are known for swaging primer pockets. In general, a swaging pin is pushed into the primer pocket. A head of the swaging pin is sized to expand the crimped portion of the primer pocket to provide the primer pocket with a relatively smooth side wall. Insertion of the new primer is then much easier and reloading results are improved.
- In one aspect, a primer pocket swager is for swaging a primer pocket of an ammunition case. The primer pocket swager includes and a case holder. The case holder is supported by the frame and is movable with respect to the frame between a loading position and an operational position. The case holder in the loading position being oriented to receive the case on the case holder. The case holder in the operational position being oriented to hold the case in position to be swaged. The case holder being configured to carry the case from the loading position to the operational position. The primer pocket swager includes a swage head supported by the frame. The swage head is sized and shaped to swage the primer pocket of the case. The swage head is movable between a retracted position and a swaging position to swage the primer pocket when the case holder is in the operational position. The primer pocket swager includes an actuator supported by the frame. The actuator is movable with respect to the frame in an actuating stroke from a home position to an actuated position. The actuator is operatively connected to the case holder such that the actuator drives the case holder to the operational position in the actuating stroke. The actuator is operatively connected to the swage head such that the actuator drives the swage head to the swaging position to swage the primer pocket
- In another aspect, a primer pocket swager includes a frame and a case holder supported by the frame. The case holder is configured to hold the case in position to be swaged. A swage shaft is supported by the frame. The swage shaft has a first swage head located at a first end of the swage shaft and a second swage head smaller than the first swage head located at a second end of the swage shaft opposite the first end. The swage shaft is movable from a retracted position to a swaging position. At least one of the first and second swage heads is oriented to swage the primer pocket when the swage shaft is in the swaging position. An actuator is supported by the frame and movable with respect to the frame in an actuating stroke from a home position toward an actuated position. The actuator is operatively connected to the first swage head such that movement of the actuator in the actuating stroke drives the swage shaft toward the swaging position to swage the primer pocket.
- In yet another aspect, a primer pocket swager includes a frame and a pivot mount supported by and pivotable with respect to the frame. A case holder is secured to the pivot mount and is configured to hold the case in position to be swaged. The pivot mount has a track. A pivot mount guide includes a follower biased against the pivot mount. The follower is configured to ride the track on the pivot mount during pivoting of the pivot mount. A swage head is supported by the frame. The swage head is movable from a retracted position to a swaging position and configured to swage the primer pocket in the swaging position. An actuator supported by the frame is movable with respect to the frame and operatively connected to the swage head to drive the swage head toward the swaging position to swage the primer pocket.

- Referring to
FIGS. 1-4 , an ammunition case primer pocket swager is designated generally by thereference number 10. Theswager 10 is configured to swage primer pockets of ammunition cases C (FIG. 4 ) to prepare the primer pockets for installation of new primers. As explained in further detail below, theswager 10 can be used to conveniently and efficiently swage primer pockets of a plurality of cases C in a relatively short amount of time. Components of the swager can be made of metal and/or plastic or any other suitable material. - In general, the
swager 10 includes aframe 12, anactuator 14, acase holder 16, and aswage shaft 18. As will become apparent, a user installs a case C on thecase holder 16 and then actuates theactuator 14. Movement of theactuator 14 in an actuating stroke causes thecase holder 16 to move from a loading position (e.g.,FIG. 4 ) to an operational position (e.g.,FIGS. 5, 6 ) to locate the case C for swaging. Movement of the actuator in the actuating stroke also causes theswage shaft 18 to move downward to a swaging position (e.g.,FIG. 6 ) swage the primer pocket. As explained further below, theswager 10 is configured to precisely position and orient the case C to achieve optimal and consistent swaging. In a return stroke of theactuator 14, theswage shaft 18 moves upward, and thecase holder 16 moves from the operational position back to the loading position. In the loading position, thecase holder 16 presents the swaged case C to the user for convenient unloading of the case and installation of another case to be swaged. - In the illustrated embodiment, the
frame 12 is provided in the form of an upstanding housing. For example, thehousing 12 can be formed of cast metal. Thehousing 12 supports the other components of theswager 10. Thehousing 12 includes a base and a superstructure extending upward from the base. The base defines a bottom 12A of the housing that is configured to rest on a surface such as a table top or other suitable surface. The base includes left, right, andrear wings 12B having respective fastener mounts 20 in the form of circular openings. For example, bolts, screws, or other fasteners (not shown) can be installed in theopenings 20 to anchor the base to a suitable surface. The body includes afront wall 12C,left side wall 12D, andright side wall 12E, and an open rear exposing an interior of the housing. Thefront wall 12C defines acase receiving recess 12F into which thecase holder 16 is movable to the operational position to carry a case C into position to be swaged. Theactuator 14 andcase holder 16 protrude forward in front of thefront wall 12C, and several other components of theswager 10 are housed in the interior of the housing behind the front wall. - In the illustrated embodiment, the
actuator 14 is provided in the form of a lever. Thelever 14 includes a proximal end adjacent thehousing 12 and a distal or free end spaced from the proximal end. The proximal end is secured to an upper pivot mount 24 at an upper end of thehousing 12. Thepivot mount 24 is pivotally connected to thehousing 12 by apin 26 and configured to pivot about a generally horizontal lever pivot axis LA defined by thepin 26. The proximal end of thelever 14 has a threaded bore and is received in a first side of thepivot mount 24. Thelever 14 is secured to the pivot mount by abolt 28 in thepivot mount 24 forming a threaded connection with the threaded bore of the lever. Thelever 14 is shown in a home position inFIGS. 1-4 . In the home position, thelever 14 extends forward and upward. Thelever 14 is pivotable downward in an actuating stroke from the home position to an intermediate position (e.g.,FIG. 5 ) and further to an actuated position (e.g.,FIG. 6 ). The actuated position can vary based on the type of case C being swaged and the adjustment of various components of theswager 10. In the actuated position, thelever 14 extends forward. The arrangement is such that a user can grip thelever 14 in the home position by hand and conveniently pull downward to actuate theswager 10 by moving the lever from the home position to the actuated position. Thelever 14 is movable in a return stroke from the actuated position back to the home position. Other types of actuators can be used without departing from the scope of the present invention. - The
case holder 16 includes a shaft having a threadedproximal portion 16A and adistal portion 16B. The distal portion is sized to receive a case C to be swaged by placing the mouth of the case over a tip of thedistal portion 16B and sliding the case downward. The threadedportion 16A is secured to alower pivot mount 30 having opposite ends received inopenings 32 in the sides of thehousing 12 pivotally connecting the lower pivot mount to the housing. Thelower pivot mount 30 defines a pivot axis CA about which the lower pivot mount and thecase holder 16 are conjointly pivotable. Thecase holder 16 is pivotable about the pivot axis CA between a loading position (e.g.,FIGS. 1-4 ) and an operational position (e.g.,FIGS. 5, 6 ). The threadedportion 16A of thecase holder 16 is threaded into a threaded opening in thelower pivot mount 30. An O-ring 34 of resiliently compressible material is carried in a circumferential groove in the threadedportion 16A to create friction in the threaded opening of thepivot mount 30 to avoid rotation of thecase holder 16 and maintain it in a desired position with respect to the pivot mount. Thecase holder 16 can be threaded into or out of thepivot mount 30 to set a depth to which the case's primer pocket will be swaged by theswage shaft 18. As shown inFIG. 4 , when thecase holder 16 is in the loading position, the case holder extends forward and upward and out of thecase receiving recess 12F at an angle with respect to vertical. In the loading position, thecase holder 16 is oriented to permit a user to conveniently access thedistal portion 16B to load cases onto and unload cases from the case holder. Thecase holder 16 is pivotable to the operational position by actuation of thelever 14 to carry the case C into positon to be swaged. Other types of case holders can be used without departing from the scope of the present invention. - Referring to
FIGS. 3-6 , the swager includes a drive linkage, generally indicated at 40, operationally connecting thelever 14 to thecase holder 16 and operationally connecting the lever to theswage shaft 18 for driving movement of the case holder and swage shaft in a sequenced manner. Thedrive linkage 40 is located behind thefront wall 12C and housed mostly in the interior of thehousing 12. In the illustrated embodiment, thedrive linkage 40 includes afirst drive train 40A operationally connecting thelever 14 to thecase holder 16 and asecond drive train 40B operationally connecting the lever to theswage shaft 18. Both the first and second drive trains 40A, 40B include the upper pivot mount 24 from which thelever 14 extends. The first and second drive trains 40A, 40B branch from the upper pivot mount 24 downward toward therespective case holder 16 andswage shaft 18. - Referring to
FIGS. 4 and 5 , thefirst drive train 40A further includes afirst link 42, asecond link 44, and athird link 46. Thefirst drive train 40A also includes thelower pivot mount 30. Thefirst link 42 is an extendable link (broadly, “lost motion link”) and is provided in the form of an extension spring. Theextension spring 42 includes anupper arm 42A, anintermediate coil portion 42B, and alower arm 42C. For example, theextension spring 42 can be formed of a continuous piece of wire. Theupper arm 42A includes a hook pivotally connecting theextension spring 42 to aneye bolt 48 threaded into theupper pivot mount 24. Theintermediate coil portion 42B defines a helical winding having several turns. Thelower arm 42C includes a hook pivotally connecting the extension spring to thesecond link 44. As explained in further detail below, theextension spring 42 is extendable from a retracted configuration (e.g.,FIGS. 4, 5 ) to an extended configuration (e.g.,FIG. 6 ) to create lost motion between thelever 14 and thecase holder 16 when the case holder is in the operational position. In the retracted configuration, consecutive turns of the helical winding 42B engage and rest against each other. In the extended configuration, the helical winding 42B is extended such that the consecutive turns of the helical winding are spaced from each other. A forward end portion of thesecond link 44 is pivotally connected to theextension spring 42. An intermediate portion of thesecond link 44 is pivotally connected to thehousing 12 by a pin orjack shaft 50 received in openings in the left andright side walls housing 12. Thesecond link 44 is pivotable about a jack shaft pivot axis JA extending along the length of thejack shaft 50. Thethird link 46 is provided in the form of two elongate bars (each indicated at 46) having upper ends on opposite sides of and pivotally connected to the rear end portion of thesecond link 44 by apin 52. The twoelongate bars 46 have lower ends pivotally connected by apin 54 to aneye bolt 56 extending from thelower pivot mount 30. Theeye bolt 56 is threaded into and conjointly pivotable with thelower pivot mount 30 like theeye bolt 48 is threaded into and conjointly pivotable with theupper pivot mount 24. As shown by comparison ofFIGS. 4 and 5 , the arrangement is such that pivoting of thelever 14 in the actuating stroke from the home position toward the actuated position causes the upper pivot mount 24 to rotate clockwise, which pulls thespring 42, creating tension force in the spring but not extending the spring, and causes thesecond link 44 to rotate counterclockwise about the jack shaft axis JA. Thesecond link 44 pushes thethird link 46, creating compression force in the third link between its pin connections, which causes thelower pivot mount 30 to rotate counterclockwise to move thecase holder 16 from the loading position toward the operational position. Accordingly, the clockwise rotation of theupper pivot mount 24 is converted by thefirst drive train 40A to counterclockwise rotation of thelower pivot mount 30. As shown by comparison ofFIGS. 4, 5, and 6 , thefirst link 42 is in its retracted configuration and does not begin extending until thecase holder 16 reaches the operational position. Desirably, thecase holder 16 reaches the operational position when thelever 14 reaches an intermediate position (e.g.,FIG. 5 ) in the actuating stroke between the home and actuated positions. As will become apparent, the extension of thespring 42 permits further pivoting of thelever 14 in the actuating stroke beyond the intermediate position to the actuated position so thesecond drive train 40B can drive theswage shaft 18 to swage the primer pocket while thefirst drive train 40A maintains thecase holder 16 in the operational position. - In view of the above, it will be apparent that the
first drive train 40A includes seven pivot connections. Three of the pivot connections are pin connections of thedrive train 40A with thehousing 12. In particular, theupper pivot mount 24 is pivotally connected to thehousing 12, thejack shaft 50 pivotally connects thesecond link 44 to the housing, and thelower pivot mount 30 is pivotally connected to the housing. In other words, three of the pivot connections are fixed with respect to thehousing 12. The other four pivot connections are movable with respect to thehousing 12 responsive to movement of thelever 14. In particular, these include the pivot connections at the opposite ends of thespring 42, and the pivot connections at the opposite ends of thethird link 46. - Referring still to
FIGS. 4 and 5 , thesecond drive train 40B will now be described in further detail. Thesecond drive train 40B includes theupper pivot mount 24, alink 60, and aram 62. Thelink 60 includes an upper end pivotally connected to theupper pivot mount 24 by apin 64. A lower end of thelink 60 is pivotally connected to theram 62 by apin 66. Theram 62 is received in aguide 12G defined by thehousing 12. Theram 62 includes alower sleeve 62A having a bore sized for receipt of theswage shaft 18. The swage shaft extends downward below theram 62. Acompression spring 68 surrounding theram 62 has an upper end engaging an upper portion of the ram and has a lower end engaging an upper portion of theguide 12G. Thecompression spring 68 biases theram 62 upward and is compressible to permit downward movement of the ram. As shown by comparison ofFIGS. 4 and 5 , the arrangement of thesecond drive train 40B is such that movement of thelever 14 in the actuating stroke from the home position toward the actuated position causes clockwise rotation of theupper pivot mount 24, which pushes on thelink 60, creating compression force between its pin connections. Thelink 60 pushes theram 62 and thus theswage shaft 18 downward for swaging the primer pocket of the case C. Accordingly, thesecond drive train 40B converts the rotational movement of the upper pivot mount 24 to translational or sliding movement of theram 62 to move theswage shaft 18 between a retracted position (e.g.,FIG. 4 ) and a swaging position (e.g.,FIG. 6 ). As shown by comparison ofFIGS. 4 and 5 , thesecond drive train 40B initially moves theswage shaft 18 downward while thefirst drive train 40A moves thecase holder 16 to the operational position. As shown by comparison ofFIGS. 5 and 6 , thesecond drive train 40B continues to move theswage shaft 18 downward after thefirst drive train 40A moves thecase holder 16 to the operational position and while the first drive train maintains the case holder in the operational position. Desirably, as thelever 14 approaches the actuated position and theswage shaft 18 approaches its swaging position, the pivot connection of the seconddrive train link 60 to the upper pivot mount 24 moves “over center” with respect to the pivot axis LA of the upper pivot mount to provide mechanical advantage in swaging the primer pocket and provide a reduction of pressure felt by the user in moving the lever downward. In particular, as theshaft 18 approaches the swaging position, the pivot axis defined by thepin 64 approaches and/or crosses a line extending between the pivot axis LA defined by thepin 26 and the pivot axis defined by thepin 66. - In view of the above, it will be appreciated that the
second drive train 40B includes three pivot connections. One of the pivot connections is a pin connection of the upper pivot mount 24 with thehousing 12. This pivot connection is fixed with respect to thehousing 12. The other two pivot connections, i.e., the pivot connections at the opposite ends of thelink 60, are movable with respect to thehousing 12 response to movement of thelever 14. - It will be appreciated that the
ram spring 68 biasing theram 62 upward with respect to theram guide 12G also biases thelever 14 toward and maintains the lever in its home position and biases thecase holder 16 toward and maintains the case holder in its loading position. When a user is not applying downward force on thelever 14, the lever is biased upward by theram spring 68 via thesecond drive train 40B. In particular, referring toFIG. 4 , thespring 68 pushes upward on theram 62, which pushes upward on thelink 60 and tends to rotate the upper pivot mount 24 counterclockwise. This in turn, via thefirst drive train 40A, tends to rotate thelower pivot mount 30 clockwise. Thelever 14 is located in its home position, and thecase holder 16 is located in its loading position, by engagement of a side of the seconddrive train link 60 with a flat 24A on theupper pivot mount 24. It will be appreciated that if thespring 42 were not in its retracted configuration when thelever 14 is in the home position, tension in thespring 42 would tend to move thecase holder 16 toward the operational position. - Other drive linkages operatively connecting the
lever 14 to thecase holder 16 and/or theswage shaft 18 can be used without departing from the scope of the present invention. For example, the lost motion link may be configured to retract rather than to extend for providing the lost motion. Moreover, other types of drive trains having other types of links are possible. - The
swager 10 includes several features that assist in properly aligning the case C with theswage shaft 18 for optimal and consistent swaging. For example, theswager 10 includes a pivotmount rotation guide 70, acase aligner 72, and acase holder stop 74. As explained in further detail below, the pivotmount rotation guide 70 promotes thecase holder 16 to move in an arcuate path that is coplanar with a swaging axis SA of theswage shaft 18. As also explained in further detail below, thecase aligner 72 andcase holder stop 74 serve to align the primer pocket of the case C with the swaging axis SA of theswage shaft 18. - Referring to
FIG. 4 , the pivotmount rotation guide 70 includes a ball bearing 70A, aspring 70B, and an actuator in the form of aset screw 70C. Theball bearing 70A, thespring 70B, and theset screw 70C are all received in an opening in thehousing 12 adjacent thelower pivot mount 30. Theset screw 70C is threaded in the opening and serves as an adjustable backing for thespring 70B, which biases theball bearing 70A against thelower pivot mount 30. Thelower pivot mount 30 includes a circumferentialarcuate slot 30A facing theball bearing 70A. Thearcuate slot 30A is rectangular in section and has left and right arcuate edges at opposite sides of the slot extending circumferentially around thelower pivot mount 30 at its outer surface. Thearcuate slot 30A can be referred to as a track, and the ball bearing 70A can be referred to as a follower on the track. In response to rotation of thelower pivot mount 30, the ball bearing 70A rides on the left and right edges of thetrack 30A. Pressure of theball bearing 70A against thetrack 30A can be adjusted by threading theset screw 70C toward or away from thelower pivot mount 30. The arrangement is such that the pivotmount rotation guide 70 promotes rotation of thelower pivot mount 30 about the axis CA perpendicular to the swage shaft axis SA and thus promotes movement of thecase holder 16 in an arcuate path coplanar with the swage shaft axis SA. In other words, the bias of theball bearing 70A against thelower pivot mount 30 “bottoms out” the opposite ends of thelower pivot mount 30 in forward ends of theopenings 32 inhousing 12, to take out any looseness or slop of the pivot connection of the lower pivot mount and the housing. This promotes alignment of thecase holder 16 left to right with respect to theswage shaft 18 when thecase holder 16 is in the operational position. Case holder mounts having other configurations can be used without departing from the scope of the present invention. Moreover, the pivot mount guide can have other configurations or be omitted. - The case aligner 72 is provided in the form of a case pusher arranged to push against the case C when the
case holder 16 is in the operational position. Thecase pusher 72 includes aplunger 72A having ahead 72B defining a case engagement surface. Theplunger 72A is slidable in aplunger guide 12H defined by thehousing 12 and is biased forward by aspring 72C. Afastener 72D (e.g., roll pin) extending through a distal end of theplunger 72A engages the plunger guide 12H to limit forward movement of the plunger. The arrangement is such that as thecase holder 16 approaches the operational position (e.g.,FIG. 5 ), theplunger 72A contacts the case C, and in response to movement of the case, the plunger moves rearward and compresses thespring 72B. The force of theplunger 72A on the case C causes the inside curved surface of the case side wall to abut the outer curved surface of thecase holder 16. This centers the case C left to right on thecase holder 16 with respect to thehousing 12. Other types of case aligners can be used, or the case aligner can be omitted, without departing from the scope of the present invention. - In the illustrated embodiment, the
case holder stop 74 is provided in the form of a thumb screw including a head orknob 74A and a threadedshaft 74B. The threadedshaft 74B is received in a threaded opening in the lower end of thehousing 12. Theshaft 74B includes a distal end positioned to engage thecase holder 16 to locate the case holder in its operational position. As shown inFIGS. 5 and 6 , the distal end of theshaft 74B (broadly, “stop surface”) engages a portion of thecase holder 16 protruding below thelower pivot mount 30 when the case holder is in the operational position. In the actuating stroke of thelever 14, when the bottom end of thecase holder 16 engages thecase holder stop 74, thefirst drive train 40A is prevented from further rotating thelower pivot mount 30, and further movement of the lever toward the actuated position causes extension of thespring 42. The operational position of thecase holder 16 can be precisely adjusted by threading thecase holder stop 74 into or out of thehousing 12. A retainer 80 (e.g., elastomeric pad or O-ring) is carried by the threadedshaft 74B and interrupts the threads of the shaft to create friction against thehousing 12 to prevent inadvertent rotation of the threadedshaft 74B and maintain thecase holder stop 74 in a desired position. The case holder stop 74 permits precise front to back adjustment of thecase holder 16 with respect to theswage shaft 18. It will be appreciated that in the operational position, the longitudinal axis of thecase holder 16 is not necessarily aligned with the longitudinal axis of theswage shaft 18. As shown inFIGS. 5 and 6 , the longitudinal axis of thecase holder 16 may point rearward such that the case C pushed forward on the case holder by thecase aligner 72 has its primer pocket in alignment with the longitudinal axis of theswage shaft 18. Other types of case holder stops can be used, or the case holder stop can be omitted, without departing from the scope of the present invention. - In an aspect of the present disclosure, the
swager 10 can be configured to swage cases having different mouth sizes. Theswager 10 can be provided with a set ofinterchangeable case holders case holders first case holder 16 is shown installed on the swager inFIGS. 1-6 . Thefirst case holder 16 can be used for cases having relatively small case mouths. Thesecond case holder 116 is shown installed on the swager inFIG. 7 . Thesecond case holder 116 has a similar construction to thefirst case holder 16. For example, thesecond case holder 116 includes a threadedproximal end portion 116A and adistal end portion 116B configured to receive a case. An O-ring 134 is carried by the threadedend portion 116A to create friction at the threaded connection of thecase holder 16 and thelower pivot mount 30. Thesecond case holder 116 has a larger diameterdistal end portion 116B and can be used for cases having relatively large case mouths. - In another aspect of the present disclosure, the
swager 10 can be configured to swage cases C having different sizes of primer pockets. In the illustrated embodiment, theswager shaft 18 includes first and second swage heads 90, 92 at opposite ends of the swaging shaft. InFIGS. 1-6 , thefirst swage head 90 is positioned for swaging a case C on thecase holder 16, and thesecond swage head 92 is in storage in theram 62. Thefirst swage head 90 is configured to swage relatively small primer pockets, and thesecond swage head 92 is configured to swage relatively large primer pockets. A case C′ having a larger primer pocket is shown inFIG. 7 . Eachswage head shaft 18. Theswage shaft 18 is releasably secured to theram 62 by aretainer 96 including ahandle 96A and apin 96B. Thepin 96B extends through aligned openings in theram 62 and theswage shaft 18. Theretainer 96 is releasably maintained in theram 62 by aball detent 96C (FIG. 2 ) protruding laterally from a side of a distal end of thepin 96B. A user can change which swagehead handle 96A of theretainer 96 rearward. When sufficient force is applied, theball detent 96C retracts into thepin 96B of theretainer 96, and the pin can be withdrawn from theram 62 andswage shaft 18. Theswage shaft 18 can then be dropped down out of theram 62, and inverted and repositioned in the ram with theother swage head 92 pointing downward for swaging. Reinstallation of theretainer 96 secures theswage shaft 18 in this inverted configuration in theram 62. - The
swage head swage shaft 18 in the return stroke of thelever 14. Areplaceable extractor 98 is provided to engage the primer pocket end of the case C and permit theswage head extractor 98 is releasably mounted on thehousing 12 by receipt in a slot in the front of the housing. Theswage shaft 18 extends through an opening in the extractor sized slightly larger than the swage shaft. A case C stuck on theswage head extractor 98 to remove the case from the swage head and drop the case back onto thecase holder 16. - In a method of using the
swager 10, the user selects whichswage head case holder swage head case holder FIG. 4 ). The user moves thelever 14 in the actuating stroke to move thecase holder 16 to the operational position (e.g.,FIG. 5 ). The user can observe the alignment of the primer pocket with respect to theswage head case holder stop 74 into or out of thehousing 12 to adjust the front to back alignment of the primer pocket with respect to theswage head 90. Moreover, thecase holder 16 can be threaded into or out of thelower pivot mount 30 to raise or lower the case C, C′ for selecting a depth theswage shaft 18 enters the primer pocket in the swaging position (e.g.,FIG. 6 ). A few cases C, C′ may be swaged and inspected to determine whether the desired swage is being achieved. Final adjustments can be made if desired. Thereafter, the user can quickly and conveniently load, swage, and unload many cases C, C′ in a convenient and efficient manner. In the actuating stroke, thelever 14 drives thecase holder 16 to the operational position and drives theswage head lever 14 and/or ramspring 68 drives thecase holder 16 to the loading position and drives theswage head lever 14 is ergonomic, and the automatic movement of thecase holder 16 between the loading and operational positions by the lever and/or ramspring 68 makes use of theswager 10 convenient and efficient. - It will be apparent that modifications and variations are possible without departing from the scope of the invention defined in the appended claims.
