FIRING- MEOHANISM FOR GUNS.

Specification of Letters Patent.

Patented Nov. 1, 1910.

Application filed June 29, 1909. Serial No. 504,966.

To all whom it may concem:

Be it' known that I, CHARLES GREEN, of Syracuse, in the countyof Onondaga and State of New York, have invented a certain new and useful Firing Mechanism for Guns,

'of which the following is a specification.

My invention has for its object the production of a particularly simple and efiicient firing mechanism for guns and it consists in the combinations and constructions hereinafter set forth and claimed. i

In describing thisinvention reference is had to the accompanying drawings in which likecharacters designate corresponding parts in all the views.

Figures 1 and 2 are elevations of the frame of a gun, showing parts of the firing mechanism indifi'erent positions and the triggers as locked together. Fig fl is a detached view' showing the triggers when not locked together. Figs. at, 5 and 61 are views of parts seen in- Fig. 3, one trigger being removed, showing, respectively, the positions of the parts of the single triggg mechanism before the first firing, immediately after the first firing, and before the second firing. Fig. 7 is a plan of parts seen in Fig. 3.

v Fig. 8 is an inverted plan, partly broken away and partly in section, of the trigger plate and triggers.

1 is the frame; 72 and ,3 are, respectively,

- the hammers and one of the main springs;

and 4 and 5 the sears'and sear springs of a double barrel gun, all of which parts may be of desirable form,"size, and construction.

6 and 7 are-left and right triggers, the upper portionso'r blades 8 and 9 of which are movable between front and rear posts 10 and 11 spaced apart on the detachable trigger plate 12 of the frame, said triggers being pivoted, respectively, at 13 and 14- to the front post 10. Saidfront post 10 is preferably formed with vertical slots or grooves 15 in which the front ends of the trigger blades 8' and ,9 extend, and the pivot 13 and upper edge or face of the trigger :blade 8 are located below the pivot 14: and

the upper edge or face of the trigger blade 9. The trigger blade :9 of the trigger 7 acts directly uponthe corresponding or'right' and the pivot 17 thereof being alined with the pivot 14 of the right trigger 7 and being usually integral therewith. This firing element or plate 16 is provided with a surface 18 of suflic'ient width to trip either of the sears l, and is also provided with a selector 19 having a part movable laterally thereon and formed with a surface 20 arranged above the surface 18. The selector can be shifted to trip either the right or left sear first, the surface 18 of the, firing plate effecting the second firing. The selector 19 is pivoted by a vertical pivot 21 on the up-- 4 per side of the firing element or plate 16 and is shifted as hereinafter described. The firing element 16 and selector 19 constitute parts associated with the trigger 6 and arranged in different planes toefiect successive firing.

22 is a member for'controlling the second firing and preventing doubling.when the.

trigger 6 is used to trip either sear, or when the trlgger 7 is connected to the trigger 6 as hereinafter explained. Said of the firing plate 16 and located between said firing plate 16 and the trigger blade 9 of the trigger 7 is shiftable forwardly. and rearwardly relative to the firing plate 16, and is also movable with said plate, and said member 22 is normally held from forward controlling member is slidablymounted'on the side face movement during the first pull of the trigger 6 (or 7 when the triggers arej'con--- nected), and the upward movement thereof with the firing plate 16 during the first pull of the trigger 6 or 7 is limite As here shown the controlling member is moved forwardly by a spring 23, and is provided with a forwardly-facing shoulder 24 which cooperates with a laterally projecting catch or shoulder25 provided on the firing plate 16. Said member 22 is-also provided with an angularly-faced shoulder 26 coact ingwith a fixed stop or shoulder 27 on the rear post 11, and'with a downw'ardly'and rearwardly inclined cam face 28 cotiperating with means as a pin 29 on the rear post 11".

The angularly-faced shoulder 26 faces upwardly and is provided with a horizontal face 30,- and with an upwardly and rearwardly inclined or beveledface 31 located in rear of and meeting the horizontal face, the

inclined face 31 eoacting with a beveled face 32 on said fixed stop 27.

The controlling member 22 is guided in its movement by pins 33 arranged on the firing eh-nnent and engaging horizontal surfaces of the controlling member 22, the rear pin 33 being slightly spaced apartfrom the horizontal surface of the cont-rolling member coacting therewith. During the first pull of the trigger 6, the upper face of the selector cf cts the tripping of one sear, and during the movement of mirdlydacing shoulder 26 encounters the listed stop 2], preventing further upward movement of the controlling 'member with the iii-lug element, but said firing element is free to continue its upward movement relatively to the coijitrolling member for a limited distance until the rear pin 33 thereon engages the controlling member and prevents further movement of the firing element relatively to the controlling member. The movement of the firing element relativcl-y to the controlling member carries the catch on the firing element 16 upwardly, out of engagement with the forwardly-facshoulder 24 of the controlling member .u-I-z, 5, leaving said member 22 free to be impelled forwardly by its spring 23. But, as seen in Fig. 5, said forward movement is regulated and retarded by reason of the engagen'ient of the inclined face 31 of the upwardly-facing shoulder 26 with the beveled face 32 of the fixed step27, so that the continued pull of the trigger, taking placev before the involuntary pull, will be of no effect. Upon the release of the trigger after the involuntary pull the spring 23 moves the controlling member forwardly withdrawing the upwardly facin shoulder 26 from under said fixed stop 2:, Fig, 6, and thus permitting the firing element 16 to be moved further upward to-bring the surface 18 of the firing element into engagement with the 'other'seiar. During the cocking of the hammers, by the breaking of the gun, the sears 4 and firingplate 16 are depressed in the usual manner forcing the cam face 28 into engagement with the pin 29 on the rear post.

11, said cam face 28 forcing the. controlling member 22, backwardly until the upwardlyfacing shoulder 26 thereof is under the fixed stop 27, Fig. 1. As thecontrolling member reaches the limit of its backwardmovement,

the spring 23'rocks said member on the front pin 33 as a pivot in a direction at an angle to the firing element, the updepressed or moved forwardly on its pivot 14 from its position shown in Fig. 3, to that shown in Fig. 1, so that its upper edge is out of position toengage the right hand sear. Thetriggers are locked together by means of a pivoted catch 34, Fig. 8, on the left hand trigger 6, which engages a pin or shoulder 35 on the right hand trigger 7, so that the triggers move as a unit when either one is pulled.- The firing plate 16 is moved by the right trigger 7 through the medium of the left trigger 6, and, said trigger 7 being depressed out of its normal position, will not act directly upon the right sear, but the firing-will be effected by the firing plate 16 and selector 19.

As seen in Figs. 1 and 2,-the means for preventing doubling or firing by the involuntary pull following the first discharge acts directl on the sears and is here shown 35 as indepen ently swinging weights 36 pivoted at 37 to the upper tang 38 of the gun and normally arranged out of the, path of the endsiof the sears and being free to swing rearwardly against the action of a weak spring over the rear ends of the sears, Fig. 2. The weights are held from swing- ,ing forwardly from their normal positions by shoulders 40 on the upper tang 38. After one sear has been tripped the corresponding weight 36 is held from swinging backwardly by the tripped sear. Fig. 2.

A safety device ,is provided for locking the triggers from movement, said safety de; y vice being here shown as a slide 41 movable along the lower face of the upper tang 38 and having aj-finger-piece 42 arranged on the outer face of said upper tang 38 and connected to the slide through a slot 43, the slide 41 also having a downwardly-extending arm 44 which engages upwardly-ex tending arms 45 on' the triggers 6 and 7. This arm 44 is formed with a l-extensional; located between front and rear laterallyextending arms 47 an'd48, provided on the selector-19. When the slide 41 is in itscentral position the arm 44 is directly over the arms 45 on the triggers for preventing move ment of the triggers. Whenthe slide 41 is shifted to'its forward position theex'tension 46 engages the front arm 47 of the selector; shifting the selector to the right, and when the slideis shifted to its rear position said extension engages the rear arm 48, shifting the selector to, the left. The swinging weights 36 also act asa safety device for preventing accidental firing, when by, falling or otherwise the butt of the gun strikesthe ground, as the force 'of the impact swings said weights 36 rearwardly over the ends of the sears.

By my invention either trigger can be used singl one to operate the right sear and the oter the left, or either-trig er can i form part of tlie's'ingle trigger mec anisrn 7 may be dispensed with if desired.
