Referring to the drawings for more specific details of the invention, the combination bullet press and reloader tool is comprised of an open ended guide sleeve member 10 having slidably disposed therein a ram 12. Integral with the guide sleeve 10 at the upper end thereof is a pair of oppositely disposed bracket arms 14 extending downwardly in spaced relation to the guide sleeve,

and a pair of upwardly extending laterally offset frame members 16 and 18 having integral therewith a frame head 20. The frame head 20 is provided with a suitable double-threaded bore therethrough and with the appropriate fittings enabling the removable attachment thereto of a variety of fixtures, such as that indicated in dotted outline at 22, each of which is adapted for a specific function. For example, the fixture 22 may be a bullet press, a cartridge re-sizer, a bullet reloader, or a cartridge primer remover for fired primer caps. Such fittings are adapted to be selectively interchangeable in the head 20 in a well known manner and for well known purposes, and such specific attachment members form no part of the present invention. The double thread characteristic of the frame head 20 ensures that the fixtures, such as 22, will be positioned in perfect axial alignment with the ram 12.

The frame or body of the tool comprised of elements 10, 16, 18 and 20 is provided with mounting means for securing the tool to the surface of a bench, or the like, indicated at 24 in Figure 1. The mounting means for the frame is composed of the following elements: a plate 26 securable to the bench surface 24,as by bolts 28; a pair of spaced bracket arms 30 secured at their lower edges to plate 26, as by welding 32, and pivotally attached at their forward ends to the arms 14 of the frame by stub shafts 34; and a pair of links 36 having their lower ends pivotally-secured to bracket arms 30 by bolts 38 and nuts 40, and having their upper ends mutually secured to the upper end of member 16 of the frame by bolt 42 and nut 44 in threaded engagement therewith. The two-point connection constituted by the pivot axes of 34 and 42 between the mounting means and the frame of the tool serves to anchor the frame in an upright position. It is to be pointed out here that the mounting means is such as to enable orientation of the frame in any desired angular disposition with respect to the vertical. For such purpose, a plurality of sets of apertures, such as the set serving to receive the bolts 38, may be formed in the bracket arms 30 to enable selective disposition of the bolts 38 and therefore a selective angular disposition of the frame of the tool, or, more properly, of the sleeve 10 and ram 12 thereof. Alternatively, links 36 of various length may be employed to selectively fix the distance between fastening elements 38 and 42 and thereby control the angular disposition of the tool frame.

The operating mechanism for the ram 12 comprises a hand lever 46 having a crank lever cross-head 48 secured thereto. One end of the cross-head 48 resides within a bifurcated end portion 50 of the ram 12 and is pivotally secured thereto by pin 52, while the other end of the cross-head 48 carries an eccentric bushing 53 in sleeved relation to a stub shaft 54 which is journalled within the ends of links 55. The cross-head 48 is provided with a set screw 56 selectively engageable with diametrically opposed recesses 57 in bushing 53. The upper ends of links 55 are pivotally secured to the frame between sleeve 10 and dependent arms 14 by stub shafts 34. The lower end of guide sleeve 10 is slotted at 60 and 62 to accommodate the cross-head 48 in its pivotal movement, which movement will be hereinafter described. The links 55 are a plurality of times the length of crosshead 48.

The ram 12 is provided at its upper end with a recess 64 for the reception of a cartridge holder member indicated generally at 66. A pin 68 secures the cartridge holder to the ram to prevent relative axial movement between the two. The cartridge holder shown in Figures 1-4 and 910 is formed at one side with a slot 76 for a purpose hereinafter described and is provided at'its upper end with an internal groove 72 serving to engage the rim 74 of a cartridge case 76.

When it is desired to move the ram 12 upwardly, as for example, to resize a fired cartridge, remove a fired primer cap, or insert a bullet within a recharged and reprimed cartridge case, the hand lever 46 is rotated-in a clockwise direction from the position shown in Figure 1. to cause that end of the cross-head 48 pivotally con- -nected to the ram to move upwardly while the other end of the cross-head is constrained to travel in an arcuate path about the axis of rotation constituted by stub shafts 34, with the result that ram 12 is forced upwardly and has a working force many times multiplied over the manual force utilized to rotate hand lever 46. During movement of the hand lever 46, the pivotal connection '52 moves upwardly in a straight line, while the pivotal connection defined by elements 56moves downwardly and laterally in an arcuate path. The cross-head 48, therefore, has both a rotative and rocking movement, and in this manner the manual force applied to handle lever 46 is multiplied and transmitted to ram 12 most efficiently throughout the period of movement of the hand level. For any given manual force applied to hand lever 46, the resultant ram or working force obtained in the tool is considerably higher than the ram force obtainable in hitherto known tools of this type, and this is due to the lever linkage system utilized to actuate the ram 12. It is also to be pointed out that when the eccentric bushing 53 is in the position of Figures 1 and 3, that is, when the stub shaft 54 is farthest removed from the handle side of the cross-head 48, the tool is set for a greater ram travel and a lesser leverage force than is the case when the bushing is offset 180 from said position, as by loosening set screw 56, rotating the bushing, and engaging the set screw with the other recess 57. The first position of the bushing, i. e., that where there is a greater ram travel and lesser leverage is to be preferred when the tool is being used for cartridge reloading, while the second position is to be preferred when the tool is used for bullet making.

The specific embodiment of the tool of the invention, as above described, is shown in Figures 9-11 as being further provided with a priming arm indicated generally at 78. The arm 78 is pivotally secured to frame arm or element 18 at 80, and, due to the fact that frame arm 18 is laterally offset with respect to the longitudinal axis of sleeve .10, as indicated in Figure 2, arm 78 is in alignment with slot 70 formed in the cartridge holder 66. Arm 78 is provided at its upper end with an internal passageway 82 in which there is disposed a vertically adjustable pin 84 having an enlarged head 86 residing within the upper end of a counter-bored cylindrical sheath 88 sleeved on pin 84. Spring 90 yieldingly urges sheath 88 against the under side of head 86, while set screw 91 serves to secure pin 84 in the desired position of vertical adjustment. Arm 78 is provided with a stop member 92 adapted to abut the sleeve when arm 78 is in the inoperative position shown in Figure 10, and the arm is further provided with a positioning member or rest in the form 'of extension 94 adapted to be engaged with the upper surface of sleeve 10 when arm 78 is in the operative position shown in Figure 9. Priming arm rest 94 serves to position the arm 78 with respect to the tool so that cup 88 is axially aligned with the primer cap aperture of a cartridge case carried by cartridge holder 66.

The priming arm 78 is, of course, utilized to insert a new primer cap within a fired cartridge case after the fired primer cap has been removed therefrom. To accomplish the repriming of a cartridge case, a primer cap is inserted within cup 88 and supported therein by head 86 of pin 84. When the ram 12 has been moved to its uppermost position, the priming arm 78 is moved from the position shown in Figure 10 to that shown in Figure 9 after pin 84 has been vertically adjusted to the desired position corresponding to the depth of insertion desired for the primer cap with respect to the cartridge case. For example, if it is desired that the outer surface of the primer cap be flush with the adjacent surface of the end of the cartridge case when the primer cap is secured thereto, the pin 84 will be so pre-set that the distance through which the sheath 88 may be moved downwardly with respect to pin 84 into engagement with arm 78 will be just suficient to bring the upper edge of the sheath 88 into alignment with the upper surface of the head 86 of pin 84. The positional adjustability of pin 84 thus enables any desired depth of insertion of the primer cap into the cartridge case, and any specific calculation and consequent setting of pin 84 for this purpose is made with reference to the bottom surface of the positioned cartridge case and not to the position 'of the ram. The actual insertion of the primer cap into the cartridge case aperture occurs, after movement of arm 78 to position of Figure 9, upon consequent downward movement of ram 12 to move the cartridge holder 66 and cartridge case carried thereby downwardly to a sufficient degree to move sheath 88 away from head 86 of pin-84 to disclose the primer cap carried thereon, and it will be particularly noted that the depth of insertion of the primer cap into the case is made dependent upon the positioning of pin 84, and hence is not dependent upon careful gauging of the appropriate degree of downward movement of the ram for this purpose, as would be the case in the event that pin 84 were not vertically adjustable.

A preferred embodiment of the complete tool of the invention is shown in Figures 5-8, whereina modified form of the cartridge holder and a modified form of the priming arm as shown. The cartridge holder, indicated generally at 166, is of the collet or chuck type and is secured to the ram 12 by pin 168. The holder 166 is formed so that the upper portion thereof is constituted by a plurality of vertically extending and circumferentially spaced segments 170 having upper or jaw portions 172, each of which is provided with an arcuate slot 174 at its inner face. The slots 174 in combination serve as the locking groove for the rim or flange 74 of cartridge case 76. The external surfaces of jaws 172 are inwardly tapered in an upward direction, and a jaw-actuating ring 178 having an internal surface 180 complementary to the external surfaces of jaws 172 is located in sleeved relation to the jaws. It will be understood that the jaws 172 are brought together in gripping relation with respect to the flange 74 of cartridge case 76 by urging ram 12 upwardly while manually holding locking ring 178 against movement along with the cartridge holder 166. Movement of the cartridge holder upwardly with respect to the locking ring for a predetermined distance causes the rim 74 of the cartridge case to be lockingly engaged within slots 174 of jaws 172. Reversely, downward movement of cartridge holder 166 with respect to locking ring 178 serves'to release the jaws 172 for flexure outwardly out of gripping engagement with the cartridge case rim.

Due to the fact that the collet type cartridge holder 166 is operable by movement of its segments with .respect to the cartridge case, it will be readily understood that a single cartridge holder may be used with cartridge cases of various calibres.

With respect to the modified form of the priming arm, this arm, indicated generally at 190, is adapted to be brought into operative position by a sliding movement, rather than a pivotal movement, as was the case with the previously described modification of the priming arm. The arm is slotted at 192 to form spaced parallel portions 194 and 196 which are slidably mounted, respectively, in slots 198 and 280 located in the rearward face of guide disc 202 secured to frame arm 18 by bolt 26M extending through slot 192 of the priming arm. As in the case of the previously described modification of the priming arm, the arm 198 is provided at its forward end with a pin 286 having a head 208, and a sheath 210 having its upper portion in sleeved relation to head 208 and its lower portion in sleeved relation to a portion of spring 212. The pin 206 is in threaded engagement with arm 190, thereby'enabling vertical adjustment of the pin to control the depth of seating of a primer cap 214 in cartridge case 76, as above described in connection with the modification of the priming arm shown in Figures 9-11. In order to vertically adjust the pin 206, means, not shown, in the form of a pair of diametrically opposed apertures in the upper end of sheath 210 and a diametral pin bore through head 288 may be provided,

whereby a wire may be inserted through said apertures and pin bore to turn pin 206 in threaded engagement with arm 190 and thereby vertically adjust said pin.

When ram 12 has been moved upwardly to a suflicient extent so that jaws 172 of the cartridge holder 166 are located above the upper edge of sheath 210, arm-190 may be slidably moved inwardly so that its forward end and the elements carried thereby pass between two of the segments 170 of the holder. Movement of the ram 12 downwardly thereupon seats the sheath 210 between the holder jaws 172, thus retaining arm 190 in priming position against the action of fiat spring 216 carried by arm 190 in engagement with the frame of the tool. After the priming operation, upward movement of the cartridge holder a predetermined degree will free the priming arm 190 for return to its inoperative position of Figure 5 under the action of spring 216.

While specific embodiments of the combination tool of the invention have been shown and described, it is to be understood that all substantially equivalents of said embodiments are within the scope of the invention.

What we claim as new and desire to secure by Letters Patent is:

A device of the class described having a frame comprised of a guide sleeve, a ram slidably disposed therein, and means for moving said ram within said guide sleeve comprising a link having one end thereof pivotally connected to the lower end of said ram, a swingable arm pivotally connected at its upper end to said sleeve a substantial distance above and in alignment with the pivotal point of connection between said ram and link, said arm having its lower end pivotally connected to the other end of said link, said arm being angularly disposed laterally from said sleeve and said link being disposed angularly upwardly and outwardly from its point of connection with the ram when said ram is at the bottom of its stroke, and said link and arm being so disposed that the pivot point between the link and arm is substantially in alignment with the axis of the ram when the ram is at the top of its stroke, and a handle lever secured to said link to move the same.
