`epccilcation forming part of Letters Patent No. LiL/178., dated J une 2, 1871i; application filed May l, 1874.

l'o all whom it may concern Be it known that we, J OIIN DEELEY, oi' Yardley, in the county of Worcester, England, manager of works, and JAMES SIMEON EDGE, thrl younger, of Yardley aforesaid, mechanical engineer', have invented certain Improvements in Breech-Loading Small-Arms, of which the following is a spcciieation:

Our invention has reference to breeclrloadin g small-arms called vertically-slidin g-bloek guns and consists of the arrangements hereinafter described, and illustrated in the accompanying drawings, of mechanism for raising and lowering the block, for cooking the striker or hammer, and for extracting the empty case ot the cartridge from the barrels of the said guns.

Figure l is a longitudinal vertical section et the breech end of a sliding-block gun, the parts ot' which are constructed and arranged accord ing to our invention. Fig. 2 represents the sai ne alter the tri ggerguard has been depressed and the breech opened and the gun cocked. Fig. 3 represents the opposite side of the gun to that represented in Fig. 2, and shows the arrangement for operating the extractor. Fig. t represents the breech-block and parts connected with it detached from the body of the gun.

a is the body of the gun, in which the vertical sliding block b works to open and close the breech. The said block bis hollow, and contains the discharge and coeking mechanism. c is the trigger-guard, turning on a joint at d on the body c, so that the said triggerguard may be raised to, or lowered from, the said body. The said trigger-guard c is furnished with a thumb-plate, c2, for operating it, and is connected to the sliding block b by the hooked arm ,c taking into a recess, b2, in the side ofthe sliding block, so that when the trigger-guard is 'aised or lowered the said block b is raised or lowered. fis the striker, sliding horizontally in the block, and urged forward by the coiled spring g. his the tum bler of the gun, turning on the center hZ at the t'ront of the sliding block b. At the front of the said tumbler is a projecting arm. h3, the said arm bearing upon the knuckle d2 of the joint of the trigger-guard c. By means of the said projecting arm h3 the tumbler l1, is cocked and i is the trigger-spring. 'which engages with the bent or notch in the on depressingl the block b, as hereinafter explained. On the head or upper side oi' the tumbler his another projection, h4, which, on the lowering of the trigger-guard and block, withdraws the striker f by bearing against the inclined shoulder f2 on the said striker. Then the tumbler h has been brought to the fullcoeked position its further motion is arrested by the stop h5 coming against the body of the gun. i is the trigger, turning on the center i2, i4 is the scar,

tumbler h, and holds it at full-cock. 7c k2 is the extractor, consisting of a lever situated and workin g in the side of the brecclrbody a. (Sec Fi fr. 3.) The lower arm k2 ofthe extractor is curved, and above it is a hooked arm, I., on the trigger-guard c. After the breech has been completely opened by the descent of the bleek b, the said hooked arm l, by acting on the arm kl of the extractor, gives motion in the proper direction to the ripper or extracting arm k, and causes the latter to extract the empty cartridgecase from the barrel of the gun.

The action ot' the gun is as follows: When the gun has been discharged, the several parts occupy the respective positions represented in Fig. l. In order to open the breech to reload the gun, the trigger-guard c is lowered from the body c, as illustrated in Figs.v2 and 3. The first action of the trigger-guard c causes its knuckle d2 to act upon the projecting aigu lr* of the tumbler, and turn the said tumbler on its center h2. By this motion the projection h4 on the upper part of the tumbler bears against the inclined shoulder f 2 on the striker f, and withdrawsthe nose of the striker into the block b, and permits the said block to descend. On the continued motion of the trigger-guard c, the bent in the tumbler h is brought opposite the scar fi", and the said scar engages therewith and cocks the gun-that is, the striker f, by the action of the parts f2 h4, has 'been pushed back and its spring compressed, the striker being held in its with drawn position by the tumbler h. During the coeking of the gun, the block b has been lowered in the body by the hooked arm c on the trigger-guard, and the breech opened, as illustrated in Fig. 2. As soon as the block I) has been lowered sufficiently to open the 2 LSL/E78 breech, the hook l on the oppositel side of.' the trigger-guard operates the extractor 7c k2, and causes the empty cartrid ge-case to be extracted from thc barrel. Thus, by the lowering of the trigger-guard c, the striker j is withdrawn and cocked and held in a cocked position, the breech opened, and the empty cartridge-ease extracted. After the introduction of a fresh cartridge into the barrel, the trigger-guard e is lifted to the body, when the sliding block Z) is again raised in the body a and the breech closed, and the gun is ready i'or discharge. 0n pulling the triggeri the sear i is liberated from the bent in the tumbler h, and the striker fis advanced by its coiled spring, and, striking the cartridge, discharges the gun, as illustrated in Fig. l. lhe trigger-guard c may be held in its raised position under the body e by a snap-fastening.

Fig. 5 represents a section, and Fig. 6 an end elevation, of a modification for connecting thejointcd triggerguard to the sliding block and for cooking the hammer. Fig. 7 is a side elevation of the block and trigger-guard detached from the body ofthe gun.

In this modification the trigger-guard c c2 is furnished with knuckles ci cf, which, are iliade to embrace the hammer m., and are jointed to the sliding block b by the center-pin m, on which the hammer m turns. The guardlever c c2 is jointed to the body a of the `gun by thejoint-pin d* and slot c5, the said slot c5 permitting the said trigger-guard to have a slight play upon the said pin c. The projecting part m4 at the front ot' the hammer my is shorter than the correspomling part in the ar- .rangements beforedescribed. \Vhen the triggerguard c c2 is first depressed it turns on the center m3. The part c7 of the said trigger-guard is thereby raised, and, by bearing against the projection m4 of the hammer in., lifts and partly cocks the said hammer. This raising oi" the short arm of the trigger-guard causes the bottom ofthe slot c5 to engage with thejoint-pin c, and the said joint-pin now constitutes `the center on which the trigger-guard turns. As

the trigger-guard 1s further depresml the block b is lowered in the body and the gun is opened for charging, the hammer m being fully cocked by the engaging ol the scar if with the bent in the said hammer.

Having explained the nature of our invention, and the manner in which the saine is to be performed, we Wish it to be understood lthat We claim as our invention oii' improve ments in those kinds of breech-loading smallarms called Vertically-slidiiig-block guns,-

l. rllhe combination, with the \'ertieally-slid ing breech-block and the jointed lever for raising and lowering said block, ot' the hammer or hammertuinbler, pivoted in and car ried by said block, and operated by tl 5 said lever to effect the coekin of the piece during the vertical descent of the block, as herein shown and set forth. y

2. Thejointed trigger-guard connected with the body ofthe gun by a loose joint, and with the sliding breech-block by the pin or center on which the hammer turns, substantially z s described, and shown in Figs. 6 and 4" ot' the .lrawings- The combination, with the 'verticallysliding breecltbloek and hammer piroted to and carried by the same, of the tri gger-guanl jointed to the body of the gun by a joint-pin, c4, and slot e5, connected with the breech-block by knuckles c, mounted and working on the center-pin. or axis ot' the hammer, and provided with a knuckle or shoulder, 0"', to operate against the projection m4 oi the hammer, substantially as described,- and shown in Figs. 5 and 6 of the dran-'ings y 4. In combination with the extractingvlever k, ther jointed trigger-guard having hook l, adapted to operate on the lower arm ot' said extracting-Jever, as shown and set forth.
