FIRE-ARM.

SPECIFICATION forming part of Letters Patent- No. 417,672, dated December 17, 1889.

Application filed October 12,1888- Serial No. 237,942- (No model.) I A 1'0 all whom it may concern Be it known that I, CHARLES Forum, a citizen ot' the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Fire-Arms,- which improvement is fully set forth in the following specification and accompanying drawings.

My invention consists of improvements in the class of fire-arms of such construction that when the hammer is down it is setback from the barrel and prevented from striking the same, or, in other words, when the hammer is discharged, it is caused to rebound, the novel features being hereinafter fully set forth.

It'also consists of a firing-pin pivotally connected with the hammer, so'as to properly enter the opening by which it is guided to the head of the cartridge.

It also consists of a guard or safety-catch, whereby the hammer cannot be cocked until it is released of 'the holding action of said guard.

Figure 1 represents a partial side elevation and partial vertical section of a fire-arm embodying my invention. Fig. 2 represents a vertical section of.a portion of the hammer,

1 being shown cocked. Fig. 3 represents a horizontal section of the firing-pin and adjacent parts on an enlarged scale. vFig. trepresents a front view of a detached portion.

Similar letters and numerals of reference denote corresponding parts in the several figures.

1 Referring to the drawings, A represents a pistol, to which, however, my invention is not limited, as the same is applicable tootherfire-arms.

B represents the hammer, C the trigger, and

ter bearing against the back of the hammer above the axis thereof, as at 1, and having connected'with it a plate or limb 2, formed of more rigid material than the main or spring.

portion, and extends angularly from the mainspring and accords with the face 3 of the hammer below the axis thereof. Projecting from said face is a pin 4, which freely enters an opening 5 in the limb 2. The said limb 2 has an opening'or eye 12, having oblique sides, through which freely passes the tapering end portion of the main part of the spring D, so that the said limb 2 rests loosely on the said end and is not rigidly secured thereon. 1

FIRE- ARMS MANU-" The operation is as follows: WVhen the ham- -1ner is at full-cock, the mainspring presses against the back of thesame, as will be seen in Fig. 2. When the hammer is released, it flies forward under impulse of. said spring, thus discharging the pistol. The heel end of the hammer then strikes the free or forward spring is exerted against the hammer below end of the limb 2, so that the pressure of the s caused to rebound and its nose or firing-pin accordingly set back from the barrel. It will be seen that when the limb 2 is first struck by the hammer on the rebound the impact thereof is first received by the said limb and forces the same more tightly upon the end of the spring before the contact of the limb vwith the heel of the hammer and the pressure on the main portion of the spring, so that the force is not so suddenly imparted to the spring, thus lessening the liability of the breaking thereof and also of the limb. By adding the limb to the mainspring of an ordinary pistol the same may be converted into a rebounder. It will also be seen that when the hammer is down the pin 4 enters the opening 5 of the limb as a guide, serving to prevent lateral displacement of said limb, and

' consequently of the-upper end of the mainspring. I

opening 11 in the seat or breech-plate of the pistol and is guided in a right line to and against the head of the cartridge instead of moving in a curved direction and striking case if the firing-pin was rigidly secured to the hammer, it being evident that the firing-- pin turns on its axis as the hammer advances, and thuss'trikes the cartridge in a right line, or a line parallel with the cartridge.

In order to connect the limb 2 with i the mainspring, it is formed with a, flattened eye 12, to receive the end of the mainspring, the

tapering or oblique, so as to form a lockingjoint between said parts, Y If desired, the eye may be formed in the spring, so as to receive the rearend of the limb; p

It is evident that any fire-arm having a mainsprin g of the character shown may have produce the rebounding action of the hammer. 1 Pivot-ed to the frame at the front of the dog F, whose nose 13 projects rearward and is adapted to comeain contact with a-shoulder 14 on the heel of the hammer at the forward end thereof. The handle 15, which is in rear of and below the pivotal point of the dog, and is heavier than the hook portion, so as hammer, partly occupies a slot 16 in the front pressed'by the hand when grasping the han-. dle. A spring 17, seated in a recess of the handle, also aids in. keeping the hook 13 in contact with the hammer.

- The hammer is of the order self-cocking or.

Having thus described my invention, what I claim as newfand desire to secure by Letters Patent, is h I V 1; A fire-arm having a hammer with a guidepin on the heel thereof, and a mainspring having'an angular extension or piece on its upper end provided with an opening to receive said pin, substantially as described. a 2. A fire-arm having a mainspring provided with a limb loosely fitted on the end thereof and adapted to engage the head ot the hammer on the other side of the pivot from that engaged by the body ofthe mainspring, whereby on the rebound of the hammerthe. impact thereof is received by the limb before the spring is affected, said parts being combined substantially as described. normally to force the said hook against the 3.
