- matic pistol, for instanoe,'a trigger, a scar,

and a magazine, and in conjunction with these arts 1' provide a novel receiver con struct on, breech'block, and firing member, the last two elementsbeing' compactly arranged within the receiver to cooperate in automatically reloading and discharging the pistolby the control of the trigger.

Considering the detail construction of the pistol, the reference numeral- 1 denotes a pistol body or frame having a receiver 2, a hollow handle 3 in communication with said receiver and adapted to contain a magazine 4, and a-barrel 5 having the rear end thereof extending into said receiver and. formed 1ntegral' with the-side wall 6 thereof, .The rear end of the barrel 5 extends into the receiver 2 approximately half the length of said receiver and forms .a chamber 7 to receive a cartridge from. the magazine 4. The rear end of the barrel 5-prov1des a longitudinal guideway 8 in the upper part of the receiver and another guidewa 9 1n the lower part of the receiver, the ormer accommodating a firing member and the latter a breech block.

The breech block comprises an oblong body 10 having the top thereof provided with a Y longitudinal roove 11 and the'bottom thereof with longitudinal grooves 12, the latter being provided to establish communlcatlon between the cartridge chamber 7 of the barrel '5 and the lower part of the receiver 2 and the hollow handle 3, thus providing means-whereby the ases can easil escape er the pistol as been discharged. The grooves 12 also reduce the weight of the breech block. One of the tudinal ribs 13 and a longitudinal groove '14. Pivotally mounted in the groove 14 walls of the body 10 is'provi'ded with longiribs 13 is an extractor 16. One end of the and retain the same against the end 0 extractor projects beyond the end of the. body and is hookshaped or prov ded with a' tooth -'17 to engage the rim of a cartildge 0 body during the rearward movement thereof, The opposite end of the extractor is" spring-pressed by acoiled spring 18 mounted in the groove 1 The forward end of the body is provided with a longitudinal pin opening 19 and with a forwardly projecting yoke or cage 20, this i yoke being off-set with the upper edge thereof in longitudinal alinement with the lower side of the body 10. The forward end of the yoke 20 isprovided with a pin openmg 21 and with a depending guide lug 22. The rear end of the body 10 is provided wlth a knob or' suitable handle 23 whereby the breech block can be easil manipulated.

The wall 6 of the pistol body has the inner side thereof provided with a longitudinal guide groove 24 for the body 10 of the breech block, said groove extending from the rear end of the barrel 5 to a slot 25 formed in the rear end of the body 1, said slot accommodating the rear end of the breech block. The wall 6 is further grooved,

as at 26 to provide clearance for the ribs 13 and the extractor 16 of the breech block, and at the forward ends of the ooves 24 and 26 the wall 6 is provided with an oblong opening 27 for the ejection of cartmdge shells, said opening being in comunication with the transverse slot 28 formed in the rear end of the barrel 5 and in the wall 6 to provide clearance for the toothed end 17 of the extractor 16. The lower part of the groove 24 extends into the guideway 9 of the receiver, as at 29 and provides a guide for one of the arms of the yoke 20' of the breech block.

Arranged in the yoke 20 of the breech block is a longitudinal pin 30, having the rear end thereof provided with a head 31 and the forward end thereof with a head 32. The forward end of the pin extends through the opening 21 of the yoke .20 and seats in a socket 33 provided therefor in the forward end of the body 1 directl beneath the barrel 5, the head 32 of sai pin anchoring the pin whereby the breech block can be independent of said pin. Encircling the pin 30 between the head'31 and the end of the yoke 20 is a coiled retractile sprin 34 adaptedto normally retain the forwar end of the breech block 10 in'engagement with the rear end of the barrel 5.

The-firing member used in connection with the breech block comprises an oblong body 35 having the rear end thereof provided with a depending lug 36 and the forward side of this lug is provided with a longitudinally disposed firing pin 37 adapted to enter the opening 19 at the-forward end of the breech block body 10. The forward end of the body 35 at one side thereof is provided with a dependingv strap 38 to partially embrace andslide upon the side of the barrel 5 at the rear end thereof. This strap extends downwardly in the yoke 20 and adjacent to said yoke is a shoulder 39 for a purpose that will presently appear. The lower end of the strap 38 is below the yoke 20 and is provided with a right-angular extension 40 adapted to be engaged 37 L within the opening 19 of the breech block, said spring being held under tension when in a cocked or rearward position and held by the sear of the trigger mechanism.

The pistol body 1 at its uncture with the hollow handle 3 .is provided with a trigger guard 44 and with an'opening 45. Pivotally mounted in the opening 45 by a transverse pin 46 is a trigger body 47 having a depending curved trigger 48 withinthe ard 44. The trigger body 47 is provided with a spring-pressed sear actuating member 49 held- 1n engagement with a sear 50 pivoted in the receiver 2 by a transverse pin 51. The sear is provided with a tooth 52 normally held in engagement with the right-angular extension 40 of the firing member by a spring 53 mounted in the receiver 2. A spring 54 mounted in the forward end of the guideway 9 normally retains the trigger body 47 in a osition that the sear actuating member 49 t ereof will engage the lower end of the sear 50.v

The hollow handle 3 of the pistol body has the rear wall 55 thereof hinged at its upper end, as at 56, whereby the magazine 4 can be easily placed in the hollow handle. Thelower end of the wall 55 is held in a closed position by a resilient clasp mounted in the lower end of the hollo handle. The magazine 4 comprises a shell having the wall thereof provided with a longitudinal slot 71 and slidably mounted insaid 'slot is the button 72 of a cartridge feeding device 58, this device including a compression spring 73, a feed spring 74, and a gate 75. The button 72 permits of the cartridge feeding device being lowered within the magazine when the same is to be loaded with cartridges. The magazine isprevented from rattling or shifting within the hollow handle 3 by a spring 59 secured to the inner upper side of the'wall 55 of the hollow handle, said magazine being further held by a small pin 60 extending into the magazine near the 4 lower end thereof The pistol body is provided with a detachable side plate 61 held in engagement with the body by screws or other fastening means 62. The plate 61 has the upper part thereof off-set to provide a guide groove 63 for the strap 38 of the firing member and the'yoke 20 of the breech block, said side "plate having a longitudinal rib 64 that engages the shoulder 39 of the strap 38 and asslsts in supporting the same during its longitudinal movement. The side plate 61 adjacent to the trigger mechanism is provided with a safety device comprising a crank shaft 65 having the outer end thereof provided with a small button or lever 66. The crank shaft 65 is adapted to engage under the spring 53 and lock the sear 50 in engagement with the right-angular extension lO of the firing member, thus preventing the sear iroin bemg moved out of engagement with handle 3 and the side said right-angular extension by a movement of the trigger. Suitable plates 67 can be mounted upon the outer side of the hollow plate 61 to provide-a hand-grip. I

A pistol in accordance with this invention is-operated in the following manner :-Assuming that the magazine 4 has been loaded and placed in the hollow handle, the upper most cartridge will be held against the under side of the breech block; the breech block is pulled rearwardly by hand and the first cartridge is immediately released from the magazine and when the breech block is released, the cartridge is carried into the chamher 7 of the barrel 5, with the rim of said,

' lar extension 40 of the firing member is engaged by the sear and held with the firing member'in a firing position. When the trigger 48 is pulled the sear 50 is shifted to release the right-angular extension 40 of the firing member and the tension of the spring 43 immediately moves the firing member forward with such force that the firing pin 37 will fire the cartridge within the chamher 7 The breech block is manually pulled rearwardly in order to load the first cartridge, but when this-cartridge is-fired the pressure of gases drives the breech block rearward I hausted of cartridges.

and the pistol is immediately reloaded by the feeding mechanism of the magazine 4 and the breech block. For repeated. firing it is only necessary to retain the finger upon" the trigger48 until the magazine 4 is ex- At each rearward movement of the breech block the cartridge shell is removed from the chamber of the barrel and ejected from the pistol.

From the foregoing it will be observed that I have devised afirearm embodying a receiver havinga' barrel projecting there-' in, a breech block normally he d in engagement'with the end or" the pro ecting barrel,
