To'dll whom] it 17m/y concern:

Beit known that I, ARTHUR W. SAVAGE, of Utica, in the county of Oneida and State of New York, have invented certain new and useful 'Improvements in Firearmsg'and Ido hereby.de`clare` that'the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains tornake and use the same, io reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form part of this specification: Y L

The main object of my present invention is to provide a hammer-indicator for a hanr. merless iirearm", which indicator has sundry Vadvantages in operation andeonstruction, as hereinafte'rfmore particularly set out, and hammer-operating-mechanism, also hereinafzo ter set forth.

Fig'ure 1 shou'stlongitndinal section of the mechanical parts of a magazine-firearm elnb'odying my present improvements with the parts in open position. Fig. 2 shows a partial z 5 longitudinal section showing the breech-bolt closed and the iiring-pin or hammer cocked. Fig. 3 shows the same as Fig. 2 after 1t/he trigger has been pulled and the tiring-pin or hannner is operated. Fig. l showsa partial section goin connection with a portion oflthe frame,

showing the hammer I retractcd by the retraetor. Fig. 5' shows a top' or plan view of a portion'of the breech-bolt. Fig. li'shows al perspective view of the frontend or tip of the hammer or firing-pin. Fig. 7 shows a retractor and its spring removed from the other- .parts and on a side elevation. Fig, 8 shows a plan view of the same.- Referring to the `reference letters and iigo nrcs in a more particular description of the device,1 indicates the barrel; 2,the fgorc-stockg :3, the butt-stock, and i the frame. Thebutt stock is secured to the frame by the screw 5 entering the rear end of the lowertangof the frame. The breech-bolt (i is provided with a wing-like projection 6, having a cani-groove, the position and Aiforin of which are shown' in dotted lines at 6" in Figs. 3 and 3,"and is operated bya linger-lever 7, pivotod to the frame gages with the wing portion of the breechbolt by a stud on the end of the arm 7 n, which is received in the cam-groove. The breeeh bolt 6 receives in a cylindrical opening in its body the hammer or ring-pin, consisting ot' 55 a spindle or shaft 9 anda head 9, having a point or tip 9", adapted to be projected through an aperture in thevfront end ot' the breech-holt and strike the'cartridge-primer. Therear endet' thehammer is provided with 6o.

hook or L-shaped-extension 9c, which is adapted to engage with the scar 10. The firing-pin or hammeris' seeured'in the breechbolt by a bushing 11 at'the rear end of' the breech-bolt, and on the-spindle of the firingpin are provided a coiled spring -12 and a washer 13. -Thehead of the .firing-pin is providedvvith a shoulder a, adapted to engage with the downwardlyextending projection pin vis cocked and in -the position shown .in Fig. 2. J The indicator letis-l'eeeived-in a recess in the top of the breech-bolt and is secured by across-pini5,-onwhich'it is pivoted,

so as to have a limited swinging movement. The washer 13 is also adapted to engage with the downwardly-extending projection 14 of the indicator 14. The searlO is pivoted ona cross-pin 'li-, extending transversely across the frame of the gun, and is operated by a 8o trigger 17, pivoted in the frame at 18 and acted upon by a tiiigger-spring 19, secured to the lower tang ofthe frame at 20.

. On the wing portion of the breech-bolt is pivoted at 21 the retractor 22, which is forked 8 5 at its frontend. to adapt it to engage on the cross-pin 16 in thev frame and is extended at its rear end'to adapt it to engage with the hooked portion 9c of the hammer or iiring-pin,

or, more particularly, the rear end of the re- 9o tractor engages on the cam 1),-formed in the front sido of this iiringfpin extensionat certain times and at other times-in the rounded notch c, formed in the lower end of this same tiring-pin' extension.- The U-shaped spring 95 223 is secured to the retractor by havingjts bent end engaged in a notch in the upper-side, and vthis spring operates the retractor by engagingon the under side of the breech-bolt.

5o at S and having a curved arm 7, which en- Oartridgcs in the magazine are indicated zoo of thefindicator 1 4 when the hammer or firing- 7o mediately vmovement ot the breechby A; but as the magazine mechanism is not involved in the present improvements detailed description and illustration are omitted.

The operation` of the device as to the firingpin indicator is as follows: YVhen the breechbolt is closed from the position shown in Fig. l (Where, the body of the breech-bolt lies irnunder the upper tang 4*"L of the frame) toward the position as shown in Figs. 2 and 3, the hooked position 9C of the ringpin or hammer is caught by the shoulder 10a on the seart'he sear being held in position to engage it by reason ofthe spring 19 operating on the trigger 17. The firing-pin is thus held back While the forward and breeehingup bolt is completed spring is compressed between the head 9a and washer13 on the front end of the firing-pin and a bushing 1l at the rear end of the breech -bolt. .When this movement is completed, the parts are in the position shown in Fig. 2. 'When the hammer .is drawn back with reference to the breech-bolt in the movement ivhich is described, the shoulder d on the front end of the ham mer engages with the projection 14a of the indicator and eauses'it' to swing on its' pivot into the position shown in Fig. 2, where its rear end projects above the general surface of the top of thebreechbolt, where it can be readily observed or felt. When the trigger' is pulled and the sear re` leases the firing-pin or hammer, itis projected forward by the operation of the spring 12, and the point or tip- 9b strikes the primer and explodes the cartridge at the salme time the` Washer 13 enga-ges with the projection 14a and forces the indicator into the closed positionshown in Fig. 3. The Washer 13 fits loosely 011 the spindle of the hammer or iiring-pin, as will be lnoted by an examination of the drawingspand in ease the firing-pin is not heldbach, either by the primeror something else, so as to take its complete forward position,l as the same is shown in Fig. 3, the Washer 13 Will be held back slightly at its upper side by the projection on the indicator, While the lower side of thewasher may follow1 the headrof the firing-pin. In case the firingpin is held back or after its blow is forced back in a slight degree by the primer orfrom any other cause the Washer 13 will still engage with the projection of the indicator and hold it in closed position.

In order to enable the liring-pin to be reand 'the ned, as shown at d, so'ihat when the bushing 11 is unfastened and the firing-pin, with its spring and head, is drawn back until the shoulder a strikes on the indicator projection it may then be given a partial rotation to bring the flat portion CZ on the upper side, when the firingpin may be completely withdrawm the vfia-t portion (Z affording no point of engagement With the projection on ihe indicator. The ringnin may be replaced by performing operations in the reverse order.

moved Without removing the indicator 14 the lfront end` of the head 9 is ilatte The object of the ret-ractor 22 draw the point 9 of theiiring`pin from projecting at the front end of the breeph-bolt after the firing-pin has operated land so asnot to-interfere with the movement of the cartridges from the magazine or in loading the gun and so as to avoid any danger of premature explosion', by reason of the firing-pin engaging with the primer of a loaded cartridge. Starting with the parts in the position in which the)T are shown in Fig..3, immediately after the shot has been discharged the first movement of the breech-bolt is downward to disengage the shoulder S on the rear of the breech-bolt from theshoulder S'on the frame. In making this movement the retractor 22 is rocked from the position shown in Fig. 3 to the position shown in Fig. 4 by reason of the forked end of the retractor engaging with the cross-pin 16, which is stationary. As the retractor 22 makes this movement the'rear end operates on the cam b, retraeting the ,ringpin slightly from the position shown in Fig. 3 to that shown in Fig. 4, andthe retractor nallycomes to rest, ivith the end engaging in the notch c. The breech-bolt then cornpletes its movement, sliding under the upper tang 4 of the frame; as illustrated in Fig. 1. As the breech-'bolt is closed again just before the completion of its vmovement the forked end of the retractor -22, then being in the position shown in Fig. 4, engages with the 'cross pin 16, and as the rear end of the breech-bolt finally rises in completingits movement and the vretractor is swung from the position shown in Fig. 4 to that shown in Fig. 2, where it is ont of the way of the firing-pin when the trigger is pulled. It Will be noted that in the closing movement of the breech-bolt there is an interval of time When'the rear end of the retractor is not engaged with the notch c in the end o'f the hammer and when the forked endis notengaged with the cross-pin 1.6. The main office of the spring 23 is to prevent at such timev the front or forked end of the retractor (which is heavier than the rear end) from dropping down into a position to not engage With the cross-pin. At other times than during such interval the retractor is held is to'with- IOO either by the cross-pin 16 or the notch c. The

spring 23 is also useful in causing the retractor 22 to assume its proper position when the parts are being assembled and the bolt is Withdrawn from the frame.

A friction device which would prevent the accidental movement of the reti-actor 22, eX- cept when it is movedin the opening or closing of the bolt by reason of the forked end engaging with the cr0ss-pin 1(3,Would answer substantially all the useful purposes ot' the spring 23.

If through any-*defect of parts or rusting or binding the indicator l14 fails to operate and close when the gun istired, the same will be rubbed down and forced into the closed position as it passes under the shoulder S and the tang 4a. The indicator 14 is prevented from opening too far by reason of thc front end cngaging with the breech-bolt at the front ond of the recess which contains the indicator, as shown particularly in Fig. 2, Fig. 3 showing the slight clearance which allows the necessary swingingl movement of the indicator, The rear end of the indicator is preferably made on an incline,affordin g a shoulder which wilf limit its .movement in closing.
