Patented Aug. 11, 193 1 t UNITE "STATES HARRY E. HOWLAND, F I'II-IACA, NEW YORK, ASSIGNOR TO ITI- IAGA GUN COMPANY, OF I PATENT oFFIc ITHAGA, NEW YORK SINGLE TRIGGER MECHANISM FOR DOUBLE BARRELED' GUNS Application filed June 18,

This invention has relation to single trigger fire mechanism for double barrel guns and has for its object the provision of certain novel constructional features pertaining particularly to the trigger and the means whereby the firing of one barrel of the gun automatically sets the barrel selecting mechanism, so that the second action of firing will fire the other barrel.

The present invention has in view as an important consideration the simplified construction and arrangement of its tripping mechanism associated with the trigger, whereby the trip carrier may be more easily taken out and replaced while the parts of the firingmechanism are being repeatedly assembled and disassembled in the manufacture of the gun.

The invention has in view further the novel construction and arrangement of certain features of the safety mechanism whereby the latter is rendered more sure and effective in its operation and preventing firing 0f the gun at untimely periods, or accidentally.

The present invention comprises'further and incidental features, the nature and purpose of which'will be made apparent in the detailed description to be hereafter glven.

In the accompanying drawings which illustrate a preferred embodiment of the invention constituting thesubject matter of this application. 7 I

Figures 1 and2 are elevations taken from opposite sides of the breech casing of a gun, showing parts broken away or omitted to better illustrate the interior mechanism;

Figure 3 is a side elevation, on an 'enlarged scale illustrating essential features of the trigger, trip and safety mechanism;

illustrated in Figure 3;

Figures '5, 6, and 7 are fragmentary transverse sectional views of the tripping devices set to different positions respectively.

As will be clearly understood the type of double barrel gun to which the invention relates is that .in which the barrels are breech loading and are opened at their loading ends by breaking them from the stock.

1928. Serial No. 286,398.

The drawings represent so much of the mechanism of this character of gun as isin the form of a plate 16, the forward end of which is provided with two upstandng ears 16, which are pivotally mounted in a recess 17 formed in an upstanding block 18 mounted on the lower tangQO and carrymg the horizontal pivotal pin 19 upon which the trigger rocks.

The trigger plate 16 includes a tail port1on 19 which projects upwardly and rear wardly above the tang 20 beyond the edge of the trigger opening and has projecting from one side a pin 21, constituting part of the safety mechanism of the gun.

The numeral 23 designates the usual ham mer and sears 24, the pivoted sears co-acting therewith. There sears have the usual forward ends 24 urged upwardly by springs 25 for engagement with shoulders on the hammer to maintain the latter-in a cooked position. The sears 24 extend rearwardly inverted T-shaped comprising a horizontally, and longitudinally pivoted block, oomprising the upstanding finger or stud 26 and the laterally extending arms 27 which latter overlap the edges of the trigger open ing through the lower tang 20. Figure 4 1s a plan view of the devices It has been'customary heretofore, in guns of the type under consideration to form the p,

trigger plate 16 with acove or recess withever, the trip is not directly pivoted to the trig r, but is eat d n a tra W or recess formed ina separate horizontally extending bar 31, which, at its forward end is mounted on the pin 19, of the recessed In its normal or inoperable position the p s endswith its l tera ly. p pj c ng ears.

To opera e 27 resting on the lower tang 21. in theselective firing of the barrels, the upstanding part of the tripis thrown to;

, .Arra-nged' real wardly. o fthe tail ioffthe trigger is a vertical. plate 32', supported on the lower tang 2O andprovided with aprojecting arm 34 on which is pivoted a lever 85. The uppergend of this lever engages spring 36 which r ests on a pin projecting laterally from the elongated and fiattenedw stem 38 of the safety slide or: buttom 39 and has its freeendformedwith a tooth orprojecti'on39" which engage withnotches I 39 in the unders de of the tang 23, and

controlled by a spring 52, one end of which:

I coact ,witlithe's prin g to indicate right, left or safety positions. -The spring fi, has an upturned lip at its forwardend, slotted for the passage of, a tenon el en the rear endof a har42, thezclatterjbeing connected the gun is' brolzen for. loading; purposes, the spring 36]' w 1ll be moved rearwardly by the rearward longitudinal 'niovement of theplate flZ, and will operate the l e'ver 3 5 and throw its lower end acr oss the pin 21 projecting from the tail of the tri gger thus locking thetrigger against firing operation of pulling closing the barrels to a firi ng position Be foreunlocking canvbe efiected, thesafety position. 1 V I:

Pivoted to the tail of the trigger is a cam havinga'forward face terminating at its lower end in a forwardly progectlngi shoulder 6L6. The rear portion of'the upper surface of'the cam indicated at l'fprov ldes a stop surface,'having its forwardl edge of slightly lessdi stance spaced fronrthe pivot point of the cam, than its rear edge."

The cam operates against the pro jecting from theinner sidejof the plate The upper; edge of the suppOrtingTplate'SQ is proyided with an angul'arly extending flange 3 2, the forward edgeff' of which is spaced from the pin l9 a distance slightly greater than the distance between the front and rear faces of the cam, so that the upper portionof the cam may operate between the two surfaces.

The lower rear edge of the cain is pro- 'VlClClWltil a stud 5O whichis connected to the flange 32 by a spring 51 which'normally urges the cam upwardly and the upper edge forwardly so that the cam. will h in eontactwiththe stop pin l9.

The function of this cam and spring 1s to normally maintain the rear end of the trigger in an elevatedrpositionso thatthe pin .21

is norinallyinaintained at a position above thelower end of the lever 35 when in a neutral position, so that this lever when moving to neutral position inust'depressthe trigger. hen the trigger is in the neutral position, and depressed the upper end of the trip'is spaced below the undersurfaces of the overhang ng portions of the sears. f

Then released'from neutral position, the

spring 51 elevates the rear end of the ..triggei' and brings the trip n contact with" '5 s the sears.

s The, selective inovements ofthe; trip are.

is fixedly attachedjto theplate132, and the 7 other end secured to the upper part of the I ,trip it. is to be 'u'nde'rstood that the main 'object and function of the cam 45 is camf frearwardly and under the projection 325011 tliejsupporting plate 32 which blocks the trigger for' an instant'be fore the trigger Assuming the gun to have been loaded,

Cockd and Placed-in afe P s t e trip will be centrally located below the sea-rs'as,

shown in lfig. 5, The spring 52 is of such l V I t construction that'it tends" to swing the upbutton must be moved forwardto disengage thelever 35 from the pin21. This moveme nt restores the plate 42 to its normal standinglink 26 of the trip beneath one of ;the sears, inthe present instance beneath the left hand soar to the position shown in 4 Fig. 6, but suchmovement is preventedi by spring 52. will throw the trip to the position shown in Fig. 6, which will cause to ele- .to' prevent doubling or premature firing of the secondbarrel after discharge of the first. when the first barrel is fired andthe trigger drops dow11,',the ,recoil for'ces the top, of the 1 vategthe left hand memberlo f thesear and ,thu's' ensurethe firing 10f the are h rd barr'lf If however the secondor righthan'd bar-'- reljis to be firechthe'fsafety button 39 will be moved to its second position, causing the lever 35 to press the 'spring52 sidew i se and throwingthe trip to the r ight, in which position it will, when the trigger is operated,

ensure the selective firing of the right hand barrel. To provide for the movement of spring 52 the forward edge of the plate 32 may be notched as indicated by the nu meral 53.

As before described, the present invention comprises the element 31, which is pivotally mounted on the pin '19 upon which the trigger is also mounted. The element 31 has therefore a small amount of motion independently of the trigger and is more sensitive in its actions.

In order to readily displace the trigger and the element 31, it is only necessary to take out the pin 19, to allow of the removal of the trigger and associated device.

This facility of disassembling and reassembling the parts is very advantageous in view of the necessity of frequently removing and replacing the parts in the manufacture of the gun, and in view of the desirability of having easily accessible and removable parts where interior changes or adjustments are required to meet the requirements or desires of the users.

What I claim as new is v In a single trigger mechanism for double barrel guns, the combination with a trigger operating through the usual trigger opening, a stationary block to which said trigger is pivoted, a bar having a width topass through said opening and being pivotally and independently mounted on the trigger pivot, said bar being formed with a transverse recess, a trip pivoted to said bar within said recess and having a lateral'length tobridge the trigger opening, means for selectively adjusting said trip, a pair of sears operatively connected to the firing mechanism, and means for selectively effecting the operation of the sears through the pulling of the trigger.

In testimony whereof I aflix my signature.

HARRY E. HOWLAND.
