Referring to the draw the breech-piece, which has hex which is pivoted to'said-part and=4 ithe Adlfof It part/sare capable of sliding@,olla-r1d'frlongitiidina channeled-part 5 ofthe h dle-or'sto vof the hammer andas extending over the spur or lug 6b .on the' hammerv side, with which its notches are intended to engage to retain the hammer 1n full or half-cocked positions, as best shown in Fig. 2. The free .endof the sear extends forwardly ofthe 'the trigger 7 is provided with a safety-finger 10, 'which 'is pivoted at its lower end to the. rear of the trigger-head, as shown, and eX- tends upwardlytherefrom to the rear of the spur or projection 9 of thesear with which it is normally held in engagement byl the action thereon of a coiled spring l0', ,which is carried within a socket in the trigger-head, as shown.in Figs. land 6. The finger 10 is provided on its `forward surface with a tooth 10, which is intended to engage and lift the sear from engagement with the hammer lug 6b at a` predetermined point in the pulling movement of the trigger, and has sits upper end projected in position to be engaged by the breech-piece 1 and moved out of coacting relation with the sear on the re'rwardmovement of th`e breechpiece, as shown in 'F ig. 10, thus preventing a release bf the hammer from cocked position until the sliding parts have returned to their'normal forward position andthe cylinder 4 llas been rotated to place the next cartridge in position for tiring. It is thus apparent that the finger 10 serves as an intermediary between the trigger and Sear and only stands in position to trip the sear on a pulling of the trigger when the sliding parts 'are in normal or firing position.

The sliding-parts have their forward movement limited by the stop-piece 11, which Vis pivoted to the stock part 5', as at 11, and

has its ^`forward end turned upward in the path otmovement of the boss 22L at the forward end of the part 2 of the breech-piece. The side edges of said upwardly turned portionare bent around the opposite sides of the stock part 5 to form finger-grips to facilitate a lowering of the stop-piece against the tension of the compression- Spring 12 vwhen it is desired to remove the` sliding-parts from the stock, as shown in Fig. 2. The stop-piece 11 has an inturned lip. 13 at its upper end adapted-to project within a groove 13 in the end of the boss 2a to prevent a lowering of the stop-piece except when the sliding-parts are moved rear` wardly from normal position to disengage said lip and groove.

The "slidinff-parts are normally held at their'lmit ofD forward movement by the acl which is carried`=by a pin 15 projecting rear- 'tion 'of the,coiled compressioli-spring 14,

and t'he'triggerto yieldingly maintain them in normal positions, as shown.

To adapt the-revolver to automatically repeat its tire until all of thecartridges in th'e'cylinder have been discharged, I pivot a llever 16 within the stock part 5 to 011e side thereof, as at 17 (see Figs.2 and 11), and j have its rear 'end terminating beneath the forward end of the seal' 9 in contiguous position thereto and its forward end terminating adjacent to the forward end of the stock Vpart 5 and turned upas shown at 16. Carried within the stock 5 by a pivot or pin 18,

which movably projects through a slot 19 in the stock nside and carries a thumb-button 20 at its outer end, (see Fig. 8), is a finger 21, which has its forward end tapered and resting on the rear end of the lever 16. lVhen the button 20 is pushed forward the nose or tapered end of the finger21 is intended to Work between the rear end of the lever 16 and the sear end and effect a raising of the forward end of the lever so that its 'upturned end stands in the path of movement of the lug 2b which is formed on the contiguous side of the boss 2 on the lbreechpart 2. It is thus apparent that on the return of the sliding-parts to their normal forward positions after a recoil, the lug 2b engages and forces the upturned end of the lever 16 down and eects a consequent raising of the rear end ofthe lever, which acts on the sear through the interposed end of the linger 21 to release the same from engagement with the hammer and permit a discharge of the next cartridge in the cylinder. The recoil of the sliding-parts from i this discharge recocks the liammer,.which is agam released 1n the same n'taypasbefore as soon as the sliding-parts return to ,their normal forward positions, thus causing the discharge of the cartridges in the cylinder to be automatically repeated with great rapidity. y

Projecting upward y from one side of the trigger-head in advance of its pivot is a finger 22, the nose of which, whenV both the breech-part 2; and the trigger are in normal positions, is intended to stand in position to engage the shoulder 23 on the contiguous side of the breech-part 2 to prevent a rearward movement ofthe sliding-parts until the trigger has been pulled suilicienlly to draw the finger down out of engaging position with said shoulder. Vith this form of lock it is possible to stop'the automatic repeating of the fire at any time by simply releasing the trigger to permit it to return to normal position.

The cylinder 4 is caused to partially rotate at each recoil movement of the sliding- Wardly from the boss 2a on the breech Yevtension part 2 and has its rear end in abutment with a lug 7a on the triggertop, thus `adapting it to act both on the sliding-parts parts to succesf-ivelyl move the chambers thereof in register with the barrel, due to a, zig-zag groove formed circumferentially thereon working over a pin 24,' which is posedportions 27, which successively con- Iicttlieopposite'ends of the portions 27, as

shown. The portions. 27 are equal in length 'to thereeoilfmovementjof the slidingl parts,

and ,have their bottoms forwardly inclined and terminating-in abrupt depressions 'which form "the Ishoulders 27EL lin the planes 'of the rear,- walls of the diagonal portions; 27. It

' is' thusk apparent that on 'the rearward movement of the sliding-parts the pin 24 will be depressedby fthe incline of the associated Way 27 to ,permititto passl over-the shoulder gammer 6 on the pivot thereof and 'has its' .50

27a, and at the' limit of such rearward movement Willbe forced outwardly by the action4 of its spring Iinto the' associatedway 27 in vabutment with said shoulder, so that on the forwardmovement' of the sliding parts the ,cylinder will be constrained to turnv due to fthe fcpe'ratingi-ation of thepin and diagonal way 27 Y lnFigs, 2`andj10, 28 designates a roller,

wardly entende'dsides l of the breech-piece andf intended 'to' .coact .with the forward Sand 1'0. The lowerend ofthe plate is'pro-l vided with a spring-catch 32, vthe outer end [of which is intended to engage a registering depression-in the stock end. To facilitate a removal of the plate from the stock, an external spring-button 33.is providedat the base of the depression and 1s adapted to be ,pressed to eii'ect a compression of the catch 32 against the tension of its spring.

-In Figs.

iece, which iscarried at the side of the earwend turned to engage the back of the jhamx'ner to limit the relative pivotal movement thereof. The forward end of the tumbler is extended in position to coact with the under sideof the tail-piece 7 of the trigger,

,as shown in Fig. 1, whereby-to cause a cock.- ing movement of the hammer to move the trigger on its' pivot so that when .r the hammer i'sin full cocked position thetrigger will have-a fixed pulling Aposition dilierent `from its .nor'mal position, thus shortening the length of pull of theI trigger to release thefsear and making a rapid firing possible. 35 designates an adjustable stoppin for `the main-spring 8'. The inner end of this pi'n is in abutment with the free end of the `1 and 10, 34 designates a tumbler spring and its outer end is threaded through the rear wall of the. stock toenable the spring'to be adjusted relativetothe hammer as `the rebound of the' hammer tosafety- 'cocked position may require, or in other words v,it is necessary 'to adjust'thespringstop softhat thespring-tension ivill'not be -brought-to bear on `the-hammer until it has rebounded to safety-cocked position.

In practice therevolver embodying -my pullingthe trigger to ycause the tail-piece7 thereofA to act on vthe hammer-piece Ga; to

which point-the tail-piece 7 releases the hammer-piece 6a to permit the discharge, as in the self-cooking revolver.' On the recoil of the sliding parts, occasioned bythe discharge, the hammer 6 is automatically recoclred and the safety-linger l0. movedv out 'of engagement-with the sear 9 to prevent a release vof the hammeruntil the .slidingparts have returned to their normal positions.y On the recoil and forward n-.ovements of the sliding-parts thefcylinder 4 is also rotated to bring the next cartridge in position to be fired, due to the `.coperating action of the yielding pin 2-landy cylinder groove, as. 'above' described. Should the thumb-button 20 and' its attached finger vil be in'rearward position vthe fire-will not be repeated until the trigger is pulled to release the sear' from the hammeigbut should"said thumb-button and finger be in forward posi= tion the lug 2a on the vbreechpartv2 will coactwith the uptur'ned'end 16 ofthe lever I6 at the limitj of forward movement of the sliding-parts, after a recoil action' thereof, and etfect an automatic'rele'ase'of the sear from the hammer,-thus 'causing the lire to be repeated as many times as there are cartridges in the cylinder, provided, of course, the trigger is maintained in pulled position. Should the trigger be released the tiring will be stopped due to the nose of the llinger Z2 thereon engaging 'the shoulder 23 on the breech-part 2 toA prevent a recoil movement of the sliding-parts. The. sliding-parts may stock by bneakmg the breech, bar-rel and cylinder groove from engagement with the down to permit the sliding-parts to be drawnoutwardly from* the stock part 5', as shown in Fig.v 2.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is,-

'1. Ina recoil ire-arm,the combination of the stock,a recoil part, a sear, a member disposed longitudinally of the stock'and pivoted thereto, said member 'having one end disposed to coact with and be moved by the recoil part at a predetermined polntnin its raise` the hammer to cocked position at- -invention-is tired inthe first instance by be easily and quickly removed from the' cylinder. in the usual manner to release the pin 24, and then drawing the stop-piecell' with the sliding breech-part, the stock, and' the sear, of a lever pivoted tothe stock in reclininer position beneath. the sliding breechpart and having its forward end fashioned to be engaged and'moved by a coperating portion of the breech-part at a predetermined point in its sliding movements and its. rear end positioned adjacent the Sear, and means actuated by a 4movement of said lever to impart a releasing movement to the Sear.

4. In a recoil lire-arm, the combination with the sliding breech-part and. the Sear, of a lever adapted to be moved by said breechpart at a predetermined point in its sliding movements and having `its rear end disposed in contiguous position to the scar, and a manually controlled member adapted to be moved intermediate the sear andrear end of I the lever to communicate a releasing moveman of the guide to coach with one of the recoil parts to limit the, forward movement of said parts relative to the; ide: and provided with'an'inturned lip W ich coacts; with one of the recoil parts to prevent. a. movement 45 of the member on its pivot to permit a withdrawal of the recoil parts from the guide e'xcept when the recoil parts are moved slightly rearwardly from normal po sition.

6..In a recoil re-arm, the combination with the sliding 'recoil parts and the stock guide therefore, of an L-sha edmember pivoted to the stock guide'an v'htinally serving as a stop for limiting the rblntive movements of the recoil parts and ,guide in one direction and coperating with one of the recoil parts when both said parts and the. member are in normal A positions whereby to. prevent a releasing movement of the member to permit a withdrawal of the recoil parts from the guide.

7 In a fire-arm, the combination ,with they hammer and trigger, said trigger having a tail-piece, of a tumbler-piece carried at the side of the hammer on the pivot thereof and 'having its rear endbent to therear 'of the hammer to limit the relative movements thereof and its forward end projected in positiontoengage the under side of the trigger tail-pieceto effect a pullingmovement of the trigger when the hammer is cocked.

' In test mony whereof I have vhereunto signed my name to this specification in the presence of two subscribing witnesses.
