vention being an improvement in the struc- :5 Hire and organization of the safety and actu ating means, having for its object the simplification of the mechanism and processes of its manufacture, and to provide a safety slid-- i'ng hammer-face that is;directl y engaged and 3c operated by the hammer-lifter pawl, the engaging detents, lugs, or surfaces being portions of said slide and lifter, acting upon each ether by immediate contact or without any intervening separable member or members, 5 as more fully hereinafter explained. I attain these objects by the mechanism shown in the "drawings, wherein- Figure 1 is aside 'view of a double-action revolver embodying my invention, the side of the frame beingbroken away to reveal the leak devices. Fig. 2 is a sectional view showing the front of the hammer, the lifter-pawl, &c., with dotted. lines indicating the relative positions of the frame and cylinder. Fig. 3 5 is a vertical sectional view illustrating the positions of the parts at the instant, of discharge. Fig. 4 illustrates the manner in which the lifter retains the hammer-face at the position of safety. Fig. 5 shows side and front detail views of the sliding hammerface separate from other parts; and Figs. 6, 7, and 8,

An example illustrate{modifications in I the form of the safety parts. y t

In practice my invention is-applicahle to a revolveror double-action firearm, whichin.

its general construction may be of well-known form and character, as shown in the drawings. v 7,

I, A indicates theframe; B, the barrel; 0, the

cylinder D,the trigger pivoted atd for swing- 6o ingaction; E, the pivoted sear,'and F the fir-' ing-pin.- j l I 'l H indicates the hammer pivoted ata' andhaving the usual lifter-engaging recess Gand sear-notch e, and .T designates the lifter or 55 pawl hinged to the head of the triggerat2 and having the lug or rearwardly-ofiset top end,,w hichengages atthe recess G for"cock,' ing the hammer by pull of thetrigger.

Kv indicates the handor pawl forturning 7o thelccylinder, which pawl may be pivoted in,

the side of the lifter and M denotes the 'mainspring, which aetuatesthe hammer-in the manner heretofore practiced. v i The part marked I represents the safety member or sliding; hammer-face, which in accordance with my inventionis providedat its front with an upper engaging lug, offset,

or shoulder 3 and alo wler engaging lug, off- .set, or shoulder 5, formed directlyin or upon the sliding face p'ieceisee Fig. 5) and having a recess or space 4: between said lugs orshoulders. Saidsliding face-piece is also formed with a straight rear edge and'a suitable cou-' tact-face for impingement on the firing-pin head. t The hammer-body has the groove h formed in its front edge and extending down to the tumbler, and said sliding hammer-face is fitted and secured in said groove to slide up and down therein and in such relation that the aforesaid lugs, offsets, or shoulders 3 and 5 immediately coact with the end or lug of the lifter-pawl J for operation of the sliding facepiece Without any intermediary member or 5' separate coupling part, thereby rendering the operation of the sliding hammer-face direct from and by the lifter, and the construction simple and of the least number of parts.

The sliding member I is provided with a longitudinal slot 11 and is retained in slidable connection with the hammer-body by a pin 6,

inserted transversely through the parts, as

\ illustrated, the slide being otherwise independent and free for control by the lifter.

' The lower offset or shoulder 5 corresponds with the bottom of the recess G in the hammer-body, or is so located as to be engaged by the lug or nose on the lifter 3 when the trigger and said lifter are at normal position, and in the event of the hammer being drawn back (see Figs. 1 and 4:) the part I is thereby kept at a position of safety should the hammer fall unintentionally. hammer-face is at depressed position, the

front of the hammer presents a space into which the head of the firing-pin is received without effecting contact therewith; but when elevated the hammer-face presents a solid portion that contacts with and forces forward the firing-pin to discharge the cartridge.

When the trigger is pulled back, as for regular discharge, and reaches the point at which the hammer is released, the lug or end of the litter is at such elevation that it impinges I against and beneath the upper lug or shoulposition for contact with the firingrpin head,

der 3 on the sliding hammer-face and as the hammer drops forces said sliding face 1 into as illustrated in'Fig. 3.

Figs. 6, 7, and'S illustrate a modified form of the sliding member-in which the lower porand 5 with each other, which bar may in some instances be desirable, as it can limit the forward swing of the lifter as it throws from the hammer in a quick self-cocking action.

I do not herein claim, broadly, the idea of When the sliding a sliding hammer-face controlled from the trigger, since such an idea in a difierently organized construction is disclosed in the Letters Patent hereinbefore noted; but my in vention comprises the improved construction whereiirthe lifter directly actuates the sliding-face member without an intermediately disposed member.

What I claim, and desire tosecure by Let ters Patent, is

1. A sliding hammer-face provided with per and under lugspifsets or shoulders adapted for direct engagement with the lug or end of the litter; in combination, with the pivoted hammer-body having said sliding hammerface mounted thereon for moving into and from contact position with the firing-pin, the lifter adapted for im pingement on said hammer-face lugs or shoulders, byits upward and downward movements, and the trigger carrying said lifter.

2. The sliding hammer-face fitting within the vertical groove in the front of the ham mer-body, and adapted for moving into and from position of contact with the firing-pin, said hammerface provided with a transverse longitudinal slot and with upper and under engaging lugs, offsets or shoulders, the latter coinciding with the bottom of the lifter recess, when depressed, in combination with the hammer-body, a fastening-pin through said body and sl0t,.the firing-pin, the swinging trigger, and the lifter hinged to said trigger and adapted for operative contact directly with the engaging lugs or shoulders on said sliding hammer-face, substantially as set forth. g
