This invention relates to gunlocks and it consists in the novel construction, combination and arrangement of parts andcooperat* ing elements herein shown, described and claimed.
An object of the invention is to provide an improved gunlock Jfor embodiment in a gun of the overand under-barrel type having the hammers arranged and mounted in such a manner thatthey strike forwardly with central. energy instead of laterally and characterized by ease of operation in cocking. In accomplishing this object the hammers or strikers are pivoted on fulcrums near` the lower part of the gunlock and are mounted in such relationship to the sears that the ring pins are struck as the hammers or strikers are thrown forwardly by their springs located vertically in the gunlock rearwardly of the barrels.
Another object of the invention is to provide a construction, combination and relationship of parts whereby outstanding ease of operation is obtained in guns of the overand under-barrel type.
Another object is to provide an improved gunlock embodying all oit' the improved features of construction and characterized by all of the advantages herein disclosed, reference being made to the accompanying drawing in which Fig. 1 is a side elevation of my improved gunlock.
Fig. 2 is a vertical longitudinal sectional view.
Fig. 3 is a rear end elevation, the trigger plate and the upper portion oi the frame being shown in section.
Fig. 4 is a vertical sectional view showing the liring pins.
My invention is embodied in a gunlock comprising a frame or receiver 1 for a gun of the overand under-barrel type. The overand underbarrels 2 are pivotally connected to the gunlock or supported in con nection with the gunlock on a pivot 3.
For the upper barrel a firing pin 4 is provided vand for the lower barrel a firing pin 5 is located directly below the pin 4.
For the upper barrel a hammer or striker 6 is pivoted on a fulcrum 7 and is provided with a laterally extended arm 8 (Fig. 3)
arranged and designed to strike the rear end .of the upper firing pin 4 when the upper barrel is to bev fired. The hammer or striker 6 is driven by a spring 9 located vertically in a spring barrel 10 in the frame or receiver 1 between the rear ends of the barrels 2 and the hammer or striker 6. i A guide plunger comprising a stem 11 extending upwardly into the lower end of the spring 9 and a head 12 forming an abutment for the lower end of said spring 9 constitute means for actuating the hammer or striker 6 by said Vspring 9. The lower pointed end of the head 12 of the plunger guide operates in a cavity 13 in the forward arm of the hammer or striker 6. A shoulder 14 is formed on one side of the hammer or striker 6 for engagement with the sear 15.
VThe sear llis pivoted on a fulcrum 16 and has a shoulder 17 on its under side arranged to engage with the shoulder 14 on the hammer or striker so as to hold the latter retracted (Fig. 2). A spring 18 is interposed between the frame or receiver 1 and a shoulder 19 on the sear 15 above the fulcrum 16 andthe power and energy of said spring is utilized to actuate the sear in a direction to engage the shoulder 17 with the shoulder 14 to hold the hammer or striker 6 cocked.
The hammer or striker 6 is cockedby a cooking plunger 20 supported for sliding movements in the Jframe or receiver 1 and having its rear end contacting with an arcuate cam 21 on the hammer or striker 6. The cam 21 is in front of the fulcrum 7 and the cocking plunger abuts against said cam 21 above the plane of said fulcrum 7 so that when the'cocking plunger is forced rearwardly as shown (Fig. 2) the hammer or striker 6 will be cocked by engaging the -shoulder 14 thereon with the shoulder 17 on the sear 15. A return spring 22 for the cocking plunger is provided7 the same encircling said cocking plunger and having its rear end abutting against a part of the frame or receiver 1 and its forward end abutting against a shoulder 23 on said cooking plunger.
A cooking cam 24 is provided for operating when fired.
Y sear 15 as shown in Fig. 2.
the cocking plunger 20 and is pivoted on a ful-V on the same tulcrum 7 on which. the hammer or striker 6 is pivoted. This hammer or striker 29 has a lateralproiection 30 designed and adapted to strike the lower striker pin 5 lt will be understood that the sear 31 for the hammer or striker 29 is exactly like the sear 15 so that specific illustration of' the sear 81 is unnecessary, as suoli illustration would be a mere duplication ot' the p Likewise it will be understood that the hammer or striker 29 "is opera-ted by a spring mounted and otherwise in all respects similar to the spring` 9 andthat a plunger guide similar' in all respects to the plunger guide 11-12 cooperates lwith the'spring tor operating the hammer or striker 29. The hammer or striker E29 is cocked byprecisely the same form of cooking device as that shown and above described for Y'cooking the hammer or striker 6. The lower rear end ot the sear 31 is designed and adapt.
ed to be engaged by a part ot a trigger 32er) as to be released in the same mannerthat the sear 15 is released by the trigger 26.
I From the foregoing it must be apparent that the gun is cocked by operation ot the cooking cams 2li and that the gun is fired by operating the triggers 26 and 32r to release the respective sears 15 and 31 Afrom the respective hammers or strikers 6 and 29.; These hammers or strikers are mounted on horizontal pivots at'the lower part ofV the fran e or receiver 1 and are driven in tiring operations by vertical springs 9 located inv vertical spring barrels at they rear ot the gun barrelsand in Jfront of the respective hammers or strikers. Firing is accomplished by a straight-'forward striking action ot the hammers with centralvized energy and the parts Vare arranged and .cooperatively mounted so as to permit and obtain outstanding ease of operation -in guns of the type mentioned, that is to say, in guns of the over-and under-barrel construction.
While the gunlock here illustrated and described is oiC particular utility in a lgun ot the overand under-barrel type, its utility is not limited to such a combination.
I am aware that the construction, arrangement and relationship of parts may be varied within equivalent limits without departing from the nature and principle of the invention' as defined by the appended claims.
.from the hammers'orstrikers.
