ONE-TRIGGER MECHANISM FOR DOUBLELBARREL IBREECH-LOADING-SMALLARMS.

' "To all whom it 'may concern:

@Be itknown that I, LESLIE BOWN TAYLOR, a subject o-f thexKing of Great Britain, residing at Grange Road, Bournbrook, near 5 Birmingham, England, have invented cer'-y tain new and useful Improvements in O ne- Double-Barrel 'xBreech-Loading SmalLArms, -of which the,

'Trigger Mechanism for following is a s'pecication.

`the new construction and arrangement or combination vof'parts hereinafter described 'whereby a ring mechanism is obtained which isfactuated by the pulling of one triggertoieffect the alternate release of the sears of the double barrel gun, the same 'two being required pull `motion ofthe trigger forthe successive release of the sears of the Y 3ha`rgedv or loaded, asthe firing mechanism lnew construction and arrangement or compulll maybe obtained without gagement with the cocked hammers, or subaoY f ,o Sipremature' v orv involuntary disturbancel "causedbyrecoilor other effect arising from' the :explosion of the cartridge.

4charge of the right hand barrel. Fig. 5 -represents a portion of the mechanism, look* ing at the right hand side of the gun, sho-wing the parts in the positions which they oc cupy after the movement of the push piece or slide of the selective mechanism of the firing mechanism to provide for the firing of the right hand barrel on the first pull of the trigger. Figs. 6 to 18 both inclusive y[My inventionrelates to one trigger mechj ranism forjdouble barrel guns and consists of lin Fig. `1) andv o are the sears; o is the single trigger, shown separately in side elevation in Fig. 6, which is jointed at c1 to the fixed or stationary block cl as is usual. Pivoted at o2 to the trigger o is a vertical lever e, shown separately in side and edge view in Figs. 7 and 8 respectively. The'said lever e is capable of a slight rocking motion on the pivot c2 but the spring f on its back edge tends to preserve it in the position represented in Fig. 1, `the acting end of the said spring bearing on the heel c3 ofthe trigger o. The rocking lever' e is providedl with side projecting studs e1, e2, e3, et.

Pivo-ted at g to the trigger plate 7L, at the rear of the rocking lever e is an upwardly i projecting clutch arm shown separately *II'will describe my invention in connection in side and edge view in Figs. 9 and 10 i respectively, the said clutch arm being re- 1of which represents partly in elevation andy tained against .too free movement by the spring pressed arm lo.

mf is a block, shown separately in side and yend elevation in Figs. 11 and 12 respectively, capable of a limited sliding motion on the'trigger plate h the -said block being moved by the push piece Z and retained in one or other position by the spring n best seen in Fig. 5. The push piece Z is lshown separately in side and end elevation the first pull on the trigger c, the rocking lever e is lifted on Athe pull on the trigger and the stud e1 acting on the heel p1 or the sear lifter p the sear lifter and lefthand sear b are raised and the lett hand hammer a released, the released hammer being actuated by the main spring s in the ordinary way. The pressure of the stud el of the rocking lever e on the heel p1 preserves the upper end of the rocking lever in close contact with the jointed clutch armz' and in the raised position of the rocking lever e' its upper end is jammed or clutched into iirm contact with an overhanging'part l of the :clutch arm i so that the two parts are temporarily interlocked Ias is represented in Fig. 2, and remain so until the pressure of the finger is positively removed from the trigger, any involuntary release of the trigger due -to recoil of the gun on firing being accompanied by a simultaneous swinging of the two parts in clutch engagement in the same direction, which preserves them interlocked. On the release of the trigger a second pull thereon brings the stud e2 into contact with the heel r1 of the right hand sear lifter 7 (see Fig:y 4) and effects the lifting of the said right hand sear lifter and the right hand searand the release of the right hand hammer. When it is desired to discharge the right hand barrel on the first pull on the trigger the shooter has only to press forward the push piece Z in the direction of the arrow in Fig. 3 when the sear lifters p, 1' are brought into the ositions with respect to the studs of the roc ing lever e represented in Fig. 5; in thisosition of the parts the trigger when pulle the first time brings the stud e3 against the heel r2 of the right hand sear lifter 1" and thereby effects the lifting i'irst of theright hand sear Z). On the second pull on lthe trigger the stud e4 is brought against the heel p? of the left hand sear lifter p which effects the lifting of the left hand sear b.

From the description hereinbefore given it will be understood that the requisite safety against 4a premature discharge of the second barrel results from the construction and arrangement of the several parts of the iiring mechanism and the same does not depend upon any extraneous and separate bolting device or devices.

For safety when carrying the gun loaded the arrangement admits of the use of nearly any of the usual safety mechanisms in connection therewith and for this reason I have not shown any one in connection with the said gun.

Having now described my invention what I claim as new and desire to secure by Letters Patent is i 1. A one trigger mechanism for double barrel breech loading small arms, consisting essentially of a trigger, a rocking lever .jointed to the rear end of the blade of the trigger, a clutch arm jointed to the trigger plate behind the rocking lever, said clutch arm having an overhanging part with which the rocking lever engages when the trigger 1s pulled for the discharge of the first barrel, and a pair of jointed arms or sear lifters which are raised by studs on the opposite sides of the rocking lever acting on heels on the rear ends of the sear litters, one only of the Sear-litters being raised on the first pull on the trigger, the sear lifters having projections with which the rear or tail ends of the sears contact or nearly so when the hammers are in their cocked positions.

2. A one trigger mechanism for double barrel breech loading small arms, consisting of the combination with one trigger of a rocking lever jointed to the rear end of the said trigger, a clutch arm jointed to the trigger plate behind the rocking lever, said clutch arm having an overhanging part with which the rocking lever engages when the trigger is pulled for the discharge of the iirst barrel, and a pair of jointed arms or sear litters which are raised by studs on the opposite sides of the rocking lever acting on heels on the rear ends of the sear lifters, only o-ne of the sear-lifters being raised on the I irst pull on the trigger, the sear lifters having projections with which the rear or tail ends of the sears contact or nearly so when the hammers are in their cocked positions and means for adjusting the sear lifters with respect to the studs on the rocking lever so as to permit the discharge of either barrel first at the will of the shooter.

3. A one-trigger mechanism for doublebarrel breech-loading small arms, consisting essentially of a trigger; a rocking lever actuated by the trigger; a pair of jointed arms or Sear-litters; and studs or projections on the rocking lever disposed to act on the searliiters when the rocking lever is actuated by the trigger, said studs or projections being so arranged that one only of the scar-litters is raised on the first pull onthe trigger, the sear-lifters having projections with which the rear or tail ends of the sears contact or nearly so when the hammers are in their cocked positions.

4. A onestrigger mechanism for doublebarrel breech-loading small arms consisting 4of a trigger; a rocking lever actuated by the so arranged that one only of the scar-litters is raised on the first pull on the trigger, the

scar-lifters having projections with which the rear ends or tails of the sears contact or nearly so vwhen the hammers are in their cocked positions; and blocking mechanism for engaging with the rocking lever on the first pull on the trigger and thereby preventing an inadvertent firing of the second barrel.

6. A one-trigger mechanism for doublebarrel breech-loading small arms, consisting of a trigger; a rocking lever actuated by the trigger; a pair of jointed arms `or scar-lifters; studs or projections on the rocking lever disposed to act on the sear-lifters when the rocking lever is actuated by the trigger, said studs or projections being so arranged that one only of the sear-lifters is raised on the rst pull von the trigger; means for adjusting the sear-lifters with respect to the studs or projections on the rocking lever so as to permit the discharge of either barrel first at the will of the shooter, the scar-litters having projections with which the rear or tail ends of the sears contact or nearly so when the hammers are in their cocked positions; and blocking mechanism for engaging with the rockin@ lever on the first pull on the trigger and thereby preventing an inadvertent discharge of the second barrel.

-7. A one-trigger mechanism for doublebarrel breech-loading small arms, comprising a trigger pivoted at its forward upper end to a Xed portion of the arm; a rocking lever pivotally connected to the upper rear portion of the trigger; a block mounted on the upper portion of the trigger and slidable thereon to one or another position to set the mechanism so as to iirst discharge the right lor the left-hand barrel; a pair of Sear-lifters, one for each Sear, pivotally connected to the block, each lifter beingprovided upon its rear face with two heels or projections, one above the other; a pair of studs projecting from each side of the lever and adapted to coperate with the heels upon the scar-lifters; a clutch-arm pivotally mounted upon the trigger plate and adapted to coperate with the lever aforesaid; and a spring carried by the lever and adapted to position the same with reference to the clutch-arm.

8. A one-trigger mechanism for doublebarrel breech-loading small arms, comprising a trigger pivoted at its forward upper end to a fixed portion of the arm; a rocking lever pivotally connected to the upper rear portion of the trigger; a block mounted on the upper portion of the trigger and slidable thereon to yone or another position to set the mechanism so as to rst discharge the right or the left-hand barrel; a pair of Sear-lifters, one for each sear, pivotally connected to the block, each lifter being provided upon its rear face with two heels or projections, one above the other; a pair of studs projecting from each side of the lever and adapted to coperate with the heels upon the scar-lifters; a clutch-arm pivotally mounted upon the trigger plate and adapted to coperate with the lever aforesaid; a spring carried by the lever and adapted to position the same with reference to the clutcharm; and a spring-pressed arm serving to prevent the too free movement of the clutch-arm.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
