Application mea August 1s, 1914. serial No. 857,371.
i the mechanism there shown to the use o-f a more powerful cartridge, such, for instance,
as a 22 caliber, long cartridge. The use of such a powerful cartridge requires the use of a heavier breech-block, and in providing a heavier breech-block it is necessary to modify and rearrange parts of the mechanism shown in said patent, especially the breech-block, trigger-plate, sear, connector, etc. In addition to this reorganization, I provide in the present invention certain improvements, as will appear.
The accompanying drawings show one eX- emplifying embodiment of the invention, but it is to be understood that the invention is capable of embodiment in many different forms and I do not limit myself to details,
- except as claimed hereinafter.
Inthe drawings: Figure 1 is a`longitudinal section through the trigger-plate, breech-block, and related parts, showing the parts in cocked position. Fig. 2 is a similar section showing the partsin fired position. Fig. 3 is a similar section showing the breech-block brought away back in the cocking or recoil movement. Fig. 4 isa transverse enlarged section on the line a-c, Fig. 2. Fig. 5is a transverse enlarged section on the line b-b, Fig. 3. Fig. 6 is a horizontal longitudinal section on the line vc--c, Fig. 3. Fig. 7 is a fragmentary vertical section on the line Z-d, Fig 2. Fig. 8 is a horizontal longitudinal section on the line awe, Fig. 2. Fig. 9 is a fro'nt, left perspective view of the trigger-plate. Fig. 10 is a perspective view of a similar positionv of; the breechblock. Fig. 11 is a perspective detail of the sear. Fig. 1 2 is a longitudinal vertical section through the forward part 0f the trigger-plate and one lform.of.guard. Fig. 13 is a perspective View of the firing-pin. Fig. 14 is a perspective view of the trigger, and Fig. 15 is a perspective view of the connector.
All the parts of the arm, in a representative embodiment, may be the same as in my Patent #1,083,384, except the parts herein shown and described, which are modified for the use of a heavier cartridge, the basis of the modification being the downward extension of the breech-block to make it heavier and the provision in the trigger-plate of a passage for this downwardly extended part of the breech-block. The trigger, sear, connector, etc. are also moved downward or rearward, speaking in general terms,to accommodate the modified breech-block.
Toward one side, the breech-block is provided with a hole 10, within whichis placed recoil spring 11 suitably guided by a rod 12, having. its end 13 removably engaging pin or stud 14 carried by lug 4. The breech-block also has a central longitudinal bore 15, in which the firing pin 16 is moimted. The iiring pin in turn has a longitudinal bore 17 containing the firingspring 18, and this is suitably supported and guided by a rod 19 terminating in a shoulder 20 bearing against lug 4 and a point 21 entering a socket in the lug to removably locate the rod in position. At its forward end, the firing pin carries -firing point 22, protruding through the hole 23 in the breech-block. Near the rear end, at the bottom, the ring pin has a scar-notch or cock-notch 24, cooperating with sear 25 pivoted upon a pin 26 inasuitable aperture in trigger-plate lug 4. The lug also has a vertical hole 27 containing sear spring 28 urging the Sear to active position. This spring 1s retained by pin 29.
' The trigger 30 is pivoted on pin 31 in the trigger-plate below the line of movement of the breech-block. It has upper side walls 32 accommodating` between them the connector 33, which is pivoted to the side walls ,of the trigger at 34. The forward end of the connector coperates with a cam 36 at the rear lower edge of the breech-block extension-4 8. The rear end of the connector has a vertical member 37, the end of which is caused to coperate with a part 38 of the sear, or with notch 39, depending upon the position of the breech-block. The sear and trigger are normally urged to the position shown in Fig. l by spring placed about connector member 37 and abutting against shoulders 4l in the trigger-plate.
When the arm is cocked, as shown'in Fig. 1, connector 33 is in normal position, with its member 37 underlying member 3S of the sear and its forward end 35 resting against cam 36 of the breech-block, and the sear 1s in engagement with the sear notch of the firing pin. 'lo fire, the trigger is pulled and this elevates the connector and releases the sear in an obvious Way. Firing reaction tlnows back the breech-block, and in the first part of its movement, cam 36, acting on the forward end 35 of the connector, moves the connector to the position shown in Fig. 3 with the upper end 4of connector member 37 opposite the notch 39 of the sear. This prevents automatic repeating before the trigger can be released. Also, any accidental pulling of the trigger during the cocking or return movement of the breech-block will now be ineffective to release the sear until the arm is in ring position ag-ain withthe breech-block in its foremost position, as in Fig'. l, whereupon carn 36 will again permitthe connector to move to active or firing position, and the arm may again be fired by pulling the trigger.
The trigger has a forward extension 42 to coperate with safety-stop 43, located in a transverse bore in the trigger-plate, forward of trigger-guard 44. This safety-stop or pin, as best seen in Fig. 7, has a notch 45, which accommodates trigger extension 42 whe-.1 the pin is in firing position; but when in safety position, or pushed to the left, as seen in Fig. 7, the rounded part 46 of the pin is opposite trigger extension 42 and the trigger cannot then be moved, and firingis impossible. The safety-pin is held in either safety or firing position with suiiicient firmness by springpressed ball 47, located in a socket 48 in the trigger-plate and cooperating with two notches 49 in the safety-pin.
As explained in my above mentioned patent, in a riie of this type, the shells are ejected through trigger-plate opening 5. To protect the hand of. the user from cooking lug 9, and for other purposes, a hand-guard 50 is provided. In the embodiment shown in Figs. l-3, this is open at the bottom and has sides 51 extending well below the cooking lug 9 and substantially in line with sides2 @nur maar:
either side of a lug 53 on the trigger-plate, forward of the trigger-guard 44, and pivotally connected to the trigger-plate by pin 54 passing through lug 53 and ears In this lug 1s also a transverse bore 55 containing y( spring 56, which urges two balls 57 into engagement with sockets 58 in ears 52 of the guard. This yielding engagement of the balls with their sockets holds the guard in active position, as shown in full lines in Figs. l, 2 and 3, but to permit access to cooking lug 9 to cock the arm, or for otherl reasons, the guard may be easily swung down, as shown in dotted lines in Fig. l. This guard may vary greatly in form and may have a bottom opening or sideI openings, or it may be, as exemplified in Fig. l2, made in the form of a cup 50a, to receive and hold ejected cartridge shells until such time as they may be conveniently removed, or act as a palm rest in firing.
The above mentioned patent fully describes how the trigger-plate with its associated parts may be removably mounted 1n a receiver or frame having a solid top and side walls and a bottom ejecting opening.
I claim l. In a firearm, the combination of a receiver having closed top and sides and a bottom ejecting opening, firing and ejecting mechanism in the receiver including aA movable member projecting through the ejecting opening, and a guard connected to the receiver by a transverse pivot and having rigid walls surrounding the ejecting-opening and projecting there-below to protect the users hand from saidmovable member, and means for holding the guard in active position.
