11a coilgspr'ing;'29is1interposed1between an up- 1 wardly extending projection 30 on the main frame and a collar 3| formed on' a sleeve 32, which extends for a distance inside of the spring 29. The sleeve 32 is screwed into the respective breech and provides a guide for the firing pin 33, on which is mounted a coil spring 34, which bears at one end against a shoulder 35 formed in the sleeve 32 and at the other end against a collar 36 fixed to the firing pin. It is apparent thatthe striking end of the firing pin is adapted to extend forwardly beyond the end of the breech through an opening 31 in the forward end portion of the breech to hit against the cartridge introduced into the respective barrel.

Each of the ring pins- 33 is releasably held in cocked or retracted position compressing the coil spring 34 by a lug 38 depending from the collar 36, which is engaged by a vertically slidable catch 39. The. catch 39 is urged upwardly by a coil spring v40, the forward exposed edge of the catch having a beveled surface 4I over which the lug 38 rides when the firing pin is moved rearwardly. Extending rearwardly or laterally of the lower end of the slide 39 is an arm 42, which is actuated by one of the spring-pressed fingers 43, two of which are pivotally mounted on a pivoted rock arm 44. It is to be understood that a catch 39 is provided for each firing pin, and a nger 43 is individual to each of the catches, but both of the fingers 43 are mounted on the rock arm 44. Depending from and integral with an intermediate portion of the rock arm 44 is a finger 45, which is urged outwardly by a coil spring 46, thereby normally holding both ofthe fingers 43 in position to engage the laterally projecting arms 42 supply new cartridges toy the barrels and at the.'y

surface. The table 60 is mounted on a post 6I, 40

which is urged upwardly by a coil spring 62. Fixed for movement with the table 60 is an upright actuating plate 63 having a beveled surface 64 at the upper end. The arrangement is such that upon rearward movement of the breech the 4J vertically disposed plate 63 is forced upwardly so that the beveled end 64 extends into a complementary shaped recess 65 in the respective breech, thereby allowing the table 60 to move upwardly and carry withit the cartridge disposed thereon 00 soy that upon forward movement ofthe breech the shell is abruptly forced into the adjacent barrel, and, subsequently, red by release. of the respective firing pin. It is to be understood that although description has been given only of one 55 breech, both breeches are constructed and operate in the same manner. y It will further be understood that when the breech 23 moves forwardly, the beveled surface 64 of the plate 63 is i engaged by the cam groove 65, thereby forcing the table 60 downwardly in position to receive the next succeeding cartridge, which is urged from the respective magazines by the usual springpressed follower 66.

A control mechanism is provided to enable manually the firearm to fire one barrel or the other independently of each other, or to enable both barrels to be fired simultaneously, or to prevent fring of both barrels. For this purp'ose a shaft 61 is mounted for turning movements in the frame I I and is provided with cams 68 and 10 formed in the intermediate portion thereof (Fig. 7.) Arranged for engagement by the cam surfaces 68 and 10 is a pair of plates 1I, which are mounted for swinging movement on a pin 12. 75

'Ihe plates 1| are adapted to be swung independently of each other by the cams 68 and 10, re. and the plates are arranged respec-4 downwardly free from engagement of the adjacent laterally projecting arm 02. In this manner, the trigger may be squeezed or pulled without ring one or the other of the barrels, according to the position of the cams 68 and l0. This is visibly indicated on the outside of the pistol by an indicator arm l2 and letters R and L disposed adjacent thereto. When the arm l2 is moved to R the right hand barrel will be in condition for firing, but the left hand barrel will be rendered inoperative or ineffective because of the depremion of the finger for such barrel. 0n the other hand, when the arm 1 2 is moved to the letter L, only the left hand barrel will be in condition for firing, and in this position the finger 03 controlling the right hand barrel, will be depresed, as above described, to render it inoperative.

When it is desired to ilre both barrels simultaneously, the indicator arm i2 is moved to the letter D, in which position both of the fingers 03 arel released to enable simultaneous release of both of the catches 30, thereby allowing both barrels to be red at the same time.

For safety purposes, such as in carrying the pistol it is desirable to have the mechanism locked or rendered ineiective so that accidental pulling or squeezing of the trigger will not fire the weapon. For this purpose the cams S0 and l0 are so constructed and arranged that upon turning the shaft 0l to such position that the indicator arm i2 is at the letter S (Fig. l) both plates 'il will be swung outwardly to render ineective both of the actuating fingers 03. Disposed between the cams 00 and 'i0 yon the shaft 0l isa notched flange 09, dog 113 pivoted on the shaft or pin I2, is adapted to snap into latching engagement with one or another notch on the flange 09 when the shaft 0l is turned to one position or another, as indicated by the letters on 'the outside of the frame. In this manner the lshaft 00 is releasably held in the individual position desired.

In order to assemble or disassemble the mechanism to enable the barrel assembly i3 to be mounted or removed, it is necessary that the breeches be retained in retracted position. For

. this purpose, a notch I6 is formed on the undersurface of each of the breeches, and engageable in the notches l0 are two spring pressed catches l5, but before the breeches can be pulled rearwardly to enable the catches to snap into engagement with the notches l0, an arm l0 which is pivoted to the main frame, must be swung outwardly. The arm i0 is provided with a pair of notches ll which slide over the shanks of the catches l5, the shanks being provided with angularly disposed shoulders so that upon forcing the arm l5 inwardly, the catches are cammed or forced downwardly.

In the alternate form shown in Figures 18 to 27, the mechanism operates substantially the same as the form above described, but in this form the breeches 23B, are disposed on the inside and a spring pressed.

I I3 of the main frame Ill. To enable the breeches to be retracted manually, a plate 18 is mounted .on the outside of the framey I and is connected by a screw .19 to the adjacent breech, the screw riding in an elongate slot in the main frame. i

In this form the barrel I3 is retained in place at its rear end by a plate 8|, which is inserted from th top surface of the barrelthroughto the main frame. The plate 8| is provided with a notched portion 82 and a pivoted catch 83 on the barrel engages this surface and retains the plate in position. The front end of .the barrel is secured by a hook 8|a on the barrel which hooks over the front end of the main frame. To cushion the recoil movement of each breech 23a, two coil springs 84 and'85are employed, one arranged above the other, the spring 84 being similar to the spring 29 above described and thev spring 85 which is somewhat weaker is disposed directly beneath and in parallel relation to the spring 84.

Although the trigger-actuatingv mechanism 'operates substantially the same as above described, the construction is somewhat different.

' 'Ihis mechanism is mounted as a unit on a frame part' 86 and comprises a pivotally mounted trigger 8l having at its upper end a transverse arm 80 on which are mounted spring-prsed ngers 00 similar tothe above described fingers 13, one being provided for each firing pin. Each nger 09 is adapted to engage a lateral L-shaped arm 00 formed on a vertically slidable firing pin catch 9| which is urged upwardly by a coiled spring 02.

The catch 0| is held in its released or downward position by a pivoted latch arm 93 which is provided with a lug engageable with a notch 05 formed in the catch 0|, a coil spring 90 urging the latch 93 to latching position.

Upon rearward movement of each breech a lug 0l which depends from each firing pin, and is normallycaught by the catch 9 l, strikes against the arm 93 thereby releasing the catch and enabling the firing pin to be released. It is further apparent that upon squeezing the trigger 8l, the spring-pressed fingers 80 move the catches 9| downwardly to release the firing pins.

To render one or the other or both barrels inoperative, slides 90 having a vertical fonte!! at one end and a cam surface |00 at the opposite end, one slide being provided for each actuating nger. By moving both slides rearwardly to swing the fingers 09 to compress their springs, both barrels are rendered inoperative, since squeezing of the trigger will not release the fir- 1 ing pins. In a similar manner, one or the vother barrel may be rendered inoperative by actuating the slide for the particular barrel. Actuation of the slides 98 is accomplished by a shaft I0! having arms |02 so arranged with respect to the cam surfaces |00 as to effect movement of one or the other, or both slides, as desired. The shaft il is turned by an indicator arm |03 similar to the arm 12, above described.

The cartridge feed operates in substantially the same manner as above described, a table 00 being resiliently mounted relative to an arm |00 which is urged upwardly to operative position by a coil spring |05. A cam lug |06 on the arm |05 is engaged by a lug |01 depending from the respective breech so that upon forward movement of the breech the arm is depressed to cartridgereceiving position. Cartridges are drawn from the magazines by spring-tension catches |06 which engage a cartridge and pull it onto the table 0 when the breech moves rearwardly.

considered necessary. n

Inv the form of vthe invention shown in Figs.

i 28 to 34, the mechanism for actuating the tiring pins andfor loading may be as above described. The important feature shown in these figures is to enable the barrels to move rearwardly or recoil with the breeches so as to lire higher powered cartridges. In this form the mounting plate and actuating mechanism as shown and described in connection with Figs. 1 to 17 may be used without modification or change. Each of the two barrels has a vertical lip |08 adjacent the rear end which is guided for horizontal movement in a groove |09 formed in the main frame and disposed in the groove is a coil spring ||0 for cushioning the rearward movement of the barrel. 'Ihe lips |08 can move rearwardly until they contact with the front end 0i.' the mounting plate lll.

It is found desirable to nold the barrels in place by keys ||2 which extend transversely through apertures in the main frame, the mounting plate and horizontally elongate grooves IIS formed in each barrel. A key is disposed at the iront and rear end portions of the barrels `and each has a notch ||4 to fit over a vertical portion of the mounting plate for retaining same against endwise movements. In addition'to holding the barrels in position the keys ||2 also serve as stops to limit the rearward movement of the barrels.

As shown the mounting plate has legs ||5 which extend downwardly and are inserted into apertures in the main frame, transverse pins I6 serving to hold the plate in position. The pins ||6 may be retained in position similar to the manner in which the pin I 5 is held, as above described.

Although I have shown and described embodiments of my invention in connection -with double barreled pistols, it is to be understood that the invention may be embodied in rifles or other weapons and, if desired, a single barreled weapon can utilize mechanism described. Numerous changes may be made in details of construction, arrangements and operation without departing from the spirit of the invention as deiined by the following claims.
