The outer end of the stem is provided with a knurled head 34 and the forward end of the stem is threaded, as at 35 and screwed into the reduced end 30 of the bore 28. The stem 32 adjacent to-,t-he threads 35 is provided with a collar 36 and encircling said stern between .the collar 36 and the inner side of the rear ,wall of the receiver 4 is a coiled i compression spring 37. This s ring serves The firing pin 39 is provide 50.

to hold the forward end of the reech block against the forward wall oft-he receiver ,4 and at the inner end of the bore 12.

The bottom of the breech block 21' is provided witha longitudinal slot 38 communicating with the bore 29; Slidably mounted in the bore 29 is a firing pin 39 having the forvard lend 40 theiipof reduced and exten in" tiron h the rin in openin 31.

b d with a defending rib 41 adapted to extendinto the slot 38 and prevent the' firing pin from rotating in the bore 29. The lower edge of the rib 41 at the rear end thereof is provided with a dependin lug 42 having a notch-43 formed therein, the object of which will presently ap ar. The firing .pin 39 is provided with a ongitudinal socket 44 and arranged in said socket is acoiled spring 45. The spring 45 encircles a rodeo having the rear end thereof threaded or otherwise fixed, as at 47 in the rear wall I of the receiver t. The coiled spring 45 extends from the rear wall of the receiver 4 to 'the forward end of the socket 44 and is adapted forward end of the bore 29. The rod 46 is of a sufficient length to extend into the socket/14 and prevent the coil spring 45 from buckling or becoming displaced when the breech block 21 is shifted.

The side walls'of. the receiver 4; below the grooves '14 and 15 are provided with longitudinal grooves 48, the forward ends of the grooves terminating at a triggeropening 49 ormed in the forward wall of the receiver 4 and at the upper end of the magazine chamber 5,' the openin 49 being opposite the forward part of tie trigger-guard 3. In the grooves 48 is slidably; mounted a trigger yoke 50 having the forward end thereof connected to a trigger 51 movably mounted in the opening d9; The forward edge of the trigger 51 is-recessed, as at 52 to provide a. finger grip.- The rear end of the trigger yoke 50 is provided with a do pending lu 53 and is also bifurcated to re ceive a roll er 54. The roller 54c is adapted to engage the beveled end 55 of a sear 56, pivotally connected to the wall of'thereceiver 4: by a screw 57. The beveled end 55 of the sear 56 is normally held-in engagement with the roller' 54 by a flat sprin 58 engaging. the sear at its rear end, .sai

spring being held by'the bottom wall of the receiver '4.

The under face of the sear 56 is provided with a curved spring. 59 and this spring is ada ted to form 'pm of asafety device carrie by the side plate 6. The safety device comprises a pin 60 revoluble in the'side plate 6, the outer end of the pin having a crank 61 with one end thereof knurled, as at 62, whereby it can be easily gripped by the finger to rotate the in 60. The inner end of the pin is provi ed with a dog 63 adapted to engage the end-of the sear 5G sear 56, whereby it cannot be actuated-by a. movement ofthe trigger yoke 50. When the dog 63 is swung downwardly past the spring 59, said spring is adapted to hold the dog 63 in an inactive position while the sear is being actuated by the yoke 50.

'Themagazine chamber 5 is provided with a vertical partition 64 parallel and in proxbetween the springs 58 and 59 and lock the imit'y to one of the walls of said chamber. 7

This partition is engaged at the upper end' thereof by the depending lug 53 of the trigger yoke 50 and thereby limits the outward movement of saidvoke and the tri get 51;

Between the partition 64 and the we 1 of the chamber 5 is a fiat spring 65 serving a twofold purpose. The upper end of the spring extends behind the lug 53 and -normally holds said lug in engagement. with the partition 64, while the lower end of the "spring 65 engages a magazine latch 66 pivotally mounted between the partition 64, and tluwall of thechamber 5 by a pin (17. Th lower end of the latch on is provided and this magazine is adapted to extend.

through the trigger yoke 50 and support a cartridge against the under side of the breech block 21.

' upwardl To place acartridge in the rear end of the b0rc l2 the handle portion 2 of therevolver is held in one hand and the stem 32.

pulled outwardl'yato move the breech block 21 toward the rear wall of the receiver 4!. As the breech block is carried reaiwvardly, the lug 2P3 of the firing pin 39 moves over tlieuppcr edge of the sear 56 until said sear engages in the notch During thisinovenieut of the breech bloclr 21 the springs 37 and 45 are placed under tension, and as soon as the breech block clears the upper end of the magazine (39, a ca rtridge is forced between the rear end of the bore 12 and t e forward end of the breech block. As the cartridge is carried upwardly the rim thereof extends under the hook of the extractor arm 94, and the nose of the cartridge pointed toward the bore 12, whereby when the stem 32 is released the tension of the spring 37 will restore the breech block '21 to its normal position, causing the forward end of said member to push the cartridge into the rear en of the bore 12. The tiring pin 35') stil. held by the sear 50 with the spring -15 under tension. When the cartridge'is forced into the bore 12 the slot 17 provides clearance for the hook shaped end 2:; of the extractor arm 24, the hook remaining in engagement with the cartridge from the time it leaves the magazine until it. has been fired and extracted from the revolver.

If it is desired to carry the revolver with a cartridge in the barrel and the firing pin and trigger ready for use, the safety device on the side plate 6 can be set to lock the sear 5t; and thus prevent accidental discharge of the weapon. The safety device can be easily shifted with the thumb while the hand is gripping the handle portion of the revolver and almost simultaneously with the shifting of the safety device the trigger 51 can be pulled to shift the sear 56 and release the-firing pin 39; The reduced end 40 of the firing pin can be arranged relatii ely to the body of the firing pin, whereby either center or rim firing cartridges can be used.

After a cartridge has been fired, the pressure of the gases drives the breech block rearwardly and the shell is witi'idrawu from the bore through the medium of the hook block has moved Sulficientl'yto place' the shell opposite the extractor opening 16, the rear en jofgtheiextractor'arm 9A: is pressed. inwardly by contacting with the face of the groove 14:, whereby the hook will'be moved out of engagement with the rim of theshell and to allowthe next cartridge coming from the magazine to force the shell from the opening 16, I i Y i Ha'vinglpow described my inventionwhat I claim-as'new, l 1.
