a ,ierring to the drawings, A denotes the m-zine; B, the bz'ir'l'ei; C, the cylinder; 31 irigger, pivoted at (Z; E, the soar, and b .e firing-pin, all. of Well-known suitable action.
nciczn'aes the hammer, which is pivoted wing upon the transverse axis-pin 2 and. ccoi'dzmee with my invention is provided it-n a, sliding hammer-face 1, arranged in connection with the upper from; pal-$3 of the ho itzer-body and secured thereto by into A ching grooves or gnideways, so as to be. firmly retained in connection but cepebie of sliding movement vertically upon the simmer front. Said hammer -face is re l as at 3, or adapted to afford an open spec or the firing-pin head when bile face I depressed and to present solid material etc when the face iselevated. The face- ;ncee i is formed short, so as to stand above one end of the lifter-pawl J, and is furnished with leccreiiyprojeciiing pin or stud 5 :iii or near its iowerend. The body of the 1mm ner is formed with the rounded lower end or tumbler notched at c for engagement with the sear E and fitted. with the usual front recess, notch, or detent; G for engagement iliore'with of the lifter J for cockin The lifter J is hinged at K to the rear part of the jgeKi'lfi lfi for action in WGil-kl'lOWIl manner in the lifting and throw-off of the hamnieiu provide said lifter with a projecti ing pin or stand 6 on the side thereof} (Sec I The pawi or kind for moving the cylinder O is not shown in the present drawings, but is in practice pivoted on the end 7 of the side of the hmmner-body is best milled olf or reduced, as at h, to afford space for said oscillating" plate which is made flat and coiniiftefihinging axis K and operates in the paratively thin, as shown in Fig. This oscillating coupler-plate is provided at its up per part with a cam or slot 15, that embraces the pin 5, fixed in the sliding hammer-face I, as indicated, while its lower part has a slot orope'ning 16, within which loosely engages the stud or pin 6, that projects from the side of the lifterJ. The opening 16 is made of such form and ample dimension as will allow the pin 6, which is fixed to the lifter, sufficient play or independent movement within said opening to permit the forward swing of the lifter in its throw-off action when raised and releasing the hammer; also, to afiord' play for said pin in the direction of the oseillation sufficient to accommodate the variancein extent of movement between that required for the lifter action and the amount of oscillation required for the coupler-plate L in shiftingthe sliding hammer-face. The coupler plate-or member L can be shaped as shown or made of any convenient shape or contour, the camslot 15 and opening 16 being formed and located therein relatively to each other substantially as described. The slot 15 is relatively inclined or so disposed that the ends of its opening will respectively range on two circles (see Fig. 5) as the plate is shifted, one
circle in corresponding to the high position of the slide I and the other circle n corresponding to the low position of said slide. Hence at any part of their oscillation the re-' lation of the plate and hammer is such that when the pin 5 is at the fore end of the slot 15 the sliding hammer-face I is then raised, and when said pin is at the rear end of the slot the sliding hammer-face is then depressed relativelyto the hammer-body. In the operation when the hammer and trigger are normally down the oscillating plate L is at forward position the slot 15 is horizonal, and the pin 5 at the rear end of the slot. The sliding hammer-face is then held depressed or at position of safety. (See Fig. 1.) If the hammer is drawn back or thumb-cocked from the. position shown in Fig. 1, the pin 5 causes the plate or lever L to oscillate about its pivot, said pin 5, however, remaining at the rear end of the slot 15, and accordingly the sliding hammer face I remains relatively depressed. In such oseillative movement the lever L may cause a certain'rnovement of the trigger through the pin 6; but if the hammer should then drop, there being no pressure or resistance on the trigger, the plaie L merely oscillates to its original position, with the pin .5 standing at the inner end of the slot, thereby keeping the sliding hammer-face at such position that there will be no contact with the tiring-pin F even if the hammer accidentally becomes released from the thumb. When the hammer is cocked by pressing on the trigger D, as in self-cocking discharge, or when the trigger is pulledfor releasing the sear from the cook-notch is, itis obvious that the.
lifter-pawl will oscillate the plate 0,; lever l by its pii 6 and that said pin will engage the by the action of the mainspring M. Consequently the pin 5 is caused to slide in the inclined slot or groove 15, the pin passin to the front end of the slot, which is held raised, as
shown in Fig. 2, and said inclined slot, acting as a cam or guide in conjunction with the pin 5, forces the sliding hammer-face upward during the forward movement of the hammer, so that when the hammer-face arrives at the firing-pin head it presents its solid portion, which contacts with the firing-pin, and eifects the discharge of the cartridge. At all move- .ments of the lock mechanism, except when the trigger is pulled and held at backward position, the parts move together and the sliding face remains depressed, thus presenting the recess or vacant space 3 to the head of the firing-pin when approaching the same. In other words, the safety-piece is always down or out of line with the firing-pin, except-'- ing when the trigger is held back, and the hammer falls while the trigger is in that position, the slide then rising while the hammer drops.
From the foregoing it will be seen that a very simple inexpensive but highly-efficient safety device is produced and the safety sliding hammer-face is adapted to the operation of double-action or self-cocking firearms.
\Vhat I claim, and desire to secure by Letters Patent, is
1. A safety mechanism for double-action firearm-locks, comprising a sliding face-piece carried upon the hammer-body and adapted to move into and from a position of contact with the firing-pin head, and an oscillating coupling member pivotally mounted upon the ham'mer-axis pin, and operatively connected with said movable face-piece and with the hammer-lifter pawl, and the trigger or means for operating said lifter-pawl, for act-ion substantially as set forth.
2. In adouble-action firearm loclgthe com binatiomwith the firing-pin, the pivoted hammer, the trigger,and the lifter-pawl hinged to the rear part of the trigger; of a sliding hammer-face movably attachedto the front of the hammer, and adapted to present a recess or space for non engagementwith the firing-pin head when at one position, and a solid face for contact with said firing-pinhead when at its other position, an oscillating member pivoted upon the hammer-axis adjacent to the side of the hammer and provided with a cam-slot and an opening, a stud or pin carried on said sliding hammer-face and embraced in said cam-slot, and a stud or pin carried on the lifter-pawl and'engaging within said opening, substantially as set forth.
3. in a doublc-action firearm-lock, incombination with the liaim1ior,tl1e iiring-pin,tl1e
trigger and the lifter hinged he said trigger;-
- a sliding hammer-face carried upon the hammer and adapted to-move into and out of position of contact with the firing-pin, an oscil lating member fulcrnmed on the hammer cen* ter pivot, means for sliding said ham men-face on the hammer-body controlled by said oscillating member, and means connecting said osciilating member with'the lifter-pawl, comprising an opening and a pin engaging there- 10 in, said opening having capacity for permitof the iifter, substantially as set forth.
