7 Claims. '(ol. 42-1) .It further has for its object a firing, trigger "-1'0 and safety mechanism wherein the trigger is .shifted transverselyof the hammer of the firing mechanism to unlock the safety mechanism and vice-versa.

It further has for its object a triggerwhich 11-5 is exposed on opposite sides of the grip handle of the fire arm or billy and operable from one side to disengageit from safety position and from the other side to retract and release the hammer when out of safety position. r

" It further has for its object an arrangement of the trigger mechanism wherein when in safety .position, the outside ofthe grip handle is practically smooth" or unobstructed from projecting parts of the trigger mechanism.

= It "further has for its object a particularly sim- .ple assembly of the parts associated. with the grip handle.

Other objects will appear throughout the specification.

' The invention'consists .in'the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had 'to'the accompanying drawing in which like char- 7 acters designate corresponding parts in all the "views.

Figure .1 is an elevation of this fire arm with the handle and barrel separated and the handle shown in section.

40 Figure 2 is a fragmentary elevation illustrat- "ing the slot in which the trigger moves, the trigger being shown in its retracted position just prior to being released.

Figure 3 is a fragmentary view illustrating in 5=elevation the opposite side of the grip handle from that shownin Figure 2.

This fire arm orbilly comprises a body including a griphandle and a barrel detachably mounted on one end of the grip handle and in line z5 therewith, firing mechanism located within the grip handle including a -spring pressed hammer -'and trigger mechanism including a trigger extending transversely through the hammer and movable therewith and also shiftable endwise arsitransversely of the hammer and the handle in order to release it from safety position to permit the operation of the trigger to fire the gun or to replace the trigger in safety position and lock it from being operated.

l designates the grip handle and 2 the barrel 5 constituting the body of the gun. The grip handle is formed with a threaded countersink or recess 3 at its breech end which receives a reduced threaded portion 4 at the inner end of the barrel 2, the threads forming means for detachably securing the barrel to the handle, the breech being detachable for the purpose of removing and inserting the cartridge 5. V

The barrel is a metal tube with annular collars 6, l at its ends between which are snugly placed fibrous material, as leather or raw-hide. The fibrous material is usually in the form of coils'or rings.

The handle I includes a metallic body portion. 8 and an internal tubular portion 9 which fits into a bore ll near the inner end of the handle at the inner end of the recess 3 fiush with the surface 3 of the recess at the inner ends of the threads, the surface 3 being in effect an internal annular shoulder at the bottom of the recess.

i2 is a breech block or plug threading into the upper end of the tube 9 and having an annular 'fiange or head it overlying the end of the tube between the collar I6 and the lower end of the body 8. A cap l8 threads on the threaded end of the tube 9 against the collar.

The firing mechanism comprises a hammer 2| 740 movable rectilinearly in the cavity formed by the tube 9 within the body 8, this being cylindrical in general form and slidably fitting the tube 9,

the firing pin'l5 being carried by the hammer at one end thereof and being preferably integral 5 therewith.

. 22 is the hammer spring. 23 designates the trigger, this being carried by the hammer and slidable or shiftable transversely thereof in a passage 2% provided in the hammer and when in one of its shifted transverse positions, is interlocked with the grip handle or body 8 thereof to hold it from movement intended to operate the hammer, and when in the other of its shifted positions, is out of safety position so that the trigger can be operated to actuate the hammer. The trigger is held in either one of its shifted positions by impositive locking means, here shown, as a poppet 25 coacting with recesses or grooves 26 formed in the trigger, the poppet being pressed by a spring 2?. The poppet and spring are located within a lengthwise chamber 28 formed in the hammer and opening through the lower end thereof, the spring being interposed between the poppet and a spring abutment 29 closing the lower open end of the passage of the hammer. The hammer spring 27 thrusts at its inner end against this abutment 29 and at its outer end against the cap i8.

The billy is provided with a strap 3! for carrying it extending through a hole in the cap and being anchored to the spring by a key 32 extending through the strap and between the end coils of the spring 22.

The body 8 is provided with a lengthwise slot 33 in one side thereof for permitting the operation of the trigger to retract and release the hammer and also with an opening 33 in the side thereof diametrically opposite the slot, this opening being in the bottom of a depression 35 in the body 8 of the grip handle. The trigger is provided with heads 36 and 3'5 at its opposite ends and the slot 33 is provided with an enlargement 38 for receiving the head 36 when the trigger is set in safety position, this enlargement 38 being located in alinement with the opening 34. When the trigger is shifted transversely of the hammer in one direction, the head 3? enters the opening 3 3, while the head 36 enters the enlargement 33, thus the trigger and hammer are locked against retracting movement or locked in' safety position and when in such position, the heads are substantially flush with the outer peripheral surface of the grip handle, the head 31 being located in the recess 35 and the head 36 in the enlargement 38. The tube 9 is formed with slots 50, ll alined with the slot 33 with its enlargement and the opening 34.

To unlock the trigger from safety position, the head 3'! is pressed through the opening 34 to the inside of the handle into the slot 5!, thus shifting the trigger 2d transversely of the ham mer so that the poppet is forced out of one groove and enters the other groove 26, and the head 33 moves out of the enlargement 38. The enlargement 38 is slightly offset laterally relative to the median line of the slot 33 and hence upon pressing laterally on the head 36, the trigger 24 is brought into alinement with the slot 33 in which position it can be slid along retracting the hammer against the spring 22. When retracted to nearly its fullest extent, the head 36 may be released, whereupon the hammer is impelled forwardly causing the firing pin to fire the cap of the cartridge. During the lateral manipulation of the trigger to carry the trigger in line with the slot 33, the hammer rocks slightly and the slot 4! in the sleeve 9 in which the head 3? slides during the operation of the hammer is wide enough to permit this rocking movement. To reset the trigger in safety position, it is merely necessary to shift it until the head 3'! again passes through the opening 34 above the bottom of the depression 35. To reload, the barrel 2 is detached from the grip handle, the old cartridge allowed to fall out, a new cartridge placed in the barrel, and the barrel replaced.

When the trigger is in safety position, the outside of the grip handle is substantially smooth so that the hilly can be used as a club without danger of unintentionally firing the cartridge. When it is desired to fire the cartridge, the trigger is readily released from its safety position by depressing the head 31 by the index finger of the hand gripping the handle and the trigger can then be retracted by the thumb.
