BREECH-LOADING FIRE-ARM.

SPEGFICATON forming part of Letters Patent No. 399,214, dated March 5, 1889.

Application filed November 3, 1888. Serial No. 289,920. (No model.)

To all whom it may concern.-

Beit known that 1, LEROY H. SMITH, a citizen of the United States, residing at Lisle, in the county of Broome and State of New York, have invented certain new and useful Improvements in Breech-Loading Guns; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to breech-loading hammerless double guns, and its object is, irst, to provide mechanical and durable means for withdrawing the locking-bolt; sec-- ond, to provide means for distinctly showing the safe mark, so that the position of the hammers maybe readily discovered even in a dim light, and at the same time to enable the manufacturer of the gun to easily stamp the said mark upon guns made principally7 of hardened metal; third, to provide a safety device whose operation is positively reliable and simple and which may be readily attached to or removed from the gun; fourth, to provide means for securing the locking-bolt in a retracted position when the gun is in, the breakdown condition for loading and for releasing the said locking-bolt by the action of closing the gun, whereby the resistance of the locking-bolt to closing the gun is avoided and the operation is made very much easier; fifth, to provide hidden means for securing the locking-bolt lever, so that the said lever cannot be either carelessly or accidentally loosened and removed or lost from the gun; sixth, to provide means for securing the mainsprin g and searsprin gs in the frame, and other minor objects, as will be more fully hereinafter described, and definitely pointed out in the claims, reference being` had to the accompanying drawings, in which- Figure I is a side elevation of a portion of a breech-loading double gun according to my invention, portions being broken away to expose interior parts and some portions shown in longitudinal vertical section. Fig. ll is a top view of the saine. Fig. III is a plan or top view of the locking-bolt and collar. Fig. IY is a top view of a port-ion of the under tang, showing certain parts in horizontal seetion at line Fig. I. Fig. V is a side elevation similar to Fig. I, but differentlybroken away to expose other interior parts. Fig. VI is an under side view of a portion of the samey 'gun with its under tang and one lock removed. Fig. VH shows a modification of the cooking-lever hook action.

10 represents the barrels pivoted at 13 to the frame 11,to swing up and down for loading in the usual manner of breakdown guns, and 12 is the wooden stock, secured, as usual, to the frame l1 by means of the two

tangs

14 and 15 of the frame and the screws 1G 17.

1S is the locking-bolt, constantly pressed forward bya concealed spring to engage the hook-shaped lug 1S) of the barrels 10,

2O is the locking-bolt lever, made integral with its shaft 2l, which is cylindrical and journaled vertically in the frame 1l.

22 is a screw threaded into the frame in the angle formed by the j uneture of the tang 14 with the body of the frame, and its en d passes through the frame into a circumferential groove in the shaft 2l, thus preventing the shaft from being drawn up out of its bearing. The screw 22 is covered and concealed by the stock l2 and kept from being worked out by the stock abutting against its head. It cannot be seen nor removed without first removing the stock. Furthermore, if this screw were threaded directly through the side of the frame it would either interfere with the firing-pin 23 (see Fig. V) or it would enter a curved portion of the frame at a slant difficult to drill and dit'ticult to make with a good finish externally.

24 is a square collar secured upon thelocking-bolt 1S by a set-screw, 25, and having in its upper face a transverse groove in which a shoe, 2G, is iitted to slide.

27 is a crank-pin projecting down from the end of the shaft 2l and journaled in the shoe 26. W'hen the lever 2O is swung to the right, it acts through the crank-pin 27, the shoe 2G, and the collar 24. to withdraw the bolt 1S, thus unlocking the barrels, so that they may be broken down for loading. The shoe 26 permitsthe transverse movementof the crank-pin,

IOO

"looseness or rattling.

whileit maintains a true mechanical bearing in tlie'collar 24, thus prevent-ing the lever 20 from The bolt 18 engages the lug' 1) at a slant, which gives it a drawing' hold that insures tightness and at the same time compensates for wear by pushing farther and farther forward. The set-screw 25 enables the collar to be adjusted upon and rigidly' secured to the bolt at such a point as will hold the lever in line on the tang when the bolt firmly set in the lug-hook.

28 is a pin fitted to slide vertically in the frame, and it is notched in its front side to receive the end of a spring', 29, whereby it is constantly pressed upward. ,This spring is rigidly held at its shank end to the frame 11 by the lower tang-plate, 30, and the screw 31, which latter passes through both plate and spring' and is threaded in the frame. The spring is curved up midway to press against the lug 1f). lVhen the bolt 18 is withdrawn and the barrels are tilted, the spring 20 presses the pin 28 up in front of the bolt 18, as shown in dotted lines, Fig. I, and holds it retracted against its spring', even though the lever 2O be set free. By this bolt-retaining device the bolt is held from obstructing the freeleturn of the barrels to place; but the act of thus returning the barrels presses the lug 19 upon the spring 2.() and draws down the pin 28, permitting the bolt 18 to spring into engagement with the lug 19). This construction not only insures the easy closing of the gun, but it prevents Athe wear on the lug 1S) and bolt 18 consequent to the usual wedging back of the bolt by the descending lug.

32 is the knob of the safety device, fitted to slide on top of the tang 14, and provided with 'a lug, 253, which extends down through a slot in the tang, where a reach, 34, is rigidly secured to it by a screw, 35. The reach 34 is spring-tempered, and, bearing its forward end up against the tang, it holds the knob 32 by friction at any point wherever the knob is set, the lug 33 being' of sufficient vertical height to permit the rear end of the spring to slide to and fro without binding' on the tang. This spring also keeps the knob from rattling. This reach is fit-ted to slide in a slot in the lower side of the tang, and is bent downward at its forward end to engage the stop-lever 3G, which is pivoted at 38 in a block, 37'that is secured rigidly to the lower tang, 15, by a screw, 39. The lower end of the lever 36 is provided with studs 40, projecting from its sides across the path of the triggers 41.

42 represents the sears, on which the triggers act, as usual, to set free the hammers in firing. Forward-a11d-backward movement is given. to the studs 40 by means of the sliding knob 32, acting through the reach 34 upon the horns of the lever 3e. Then in its middle position, the stud 40 will be directly over the knob of the trigger and prevent the trigger being' pulled, so that the gun cannot then be discharged but when the stud 4() is either in its forward or rear position the knob 43 may pass up byit and the gun may be discharged.

To maintain` the stud 40 in any one of the positions named, an are of teeth, 44, is provided on the side of lever 36, forming between. them three notches to be engaged by a springcatch, 45, arranged in the block 37. Then the lever is forcibly pressed either way, the catch is wedged out of 'the teeth; but before being thus thrown out the catch will hold the lever in any one of its positions with sufficient firmness to prevent its being' jarred out or otherwise accidentally displaced.

4G is a push-pin fitted to slide freely in the frame l1 in line between the collar 24 and the lever 36. Retracting the bolt 18 to unlock and open the gun pushes the pin 4G back, thereby setting the lower end of lever 36 forward with its studs 40 out of line with the trigger-knob 43. This is necessary to be done, because the act of opening this gun cocks the concealed hammers, and when the gun is elosedagain it should be ready to he fired. By thus communicating motion through the pin 4G and collar 24 to the bolt 18 the safety device always bears a fixed relation to the boltmovement, even though the bolt be set forward in the collar to compensate for wear.

At 47 the word Safe is stamped into the top of the tang to be seen through a window, 48, in the slide-knob 32 at the time when the studs 40 are over the knobs 43 of the triggers. As the triggers cannot then be pulled, the gun cannot be fired; therefore the sign Safe is then exposed. lf the knob 32 be either forward or back of the aforesaid position, the triggers are free to be pulled to fire the gun, and the word Safe is then covered by the knob.

in order that the condition of the safety device may be seen in a dim light, a piece of light-colored metal, 47such as gold, silver, or brass-is set permanently into the tang to receive the stamped letters Safe. The knob 32 is a dead dark color from case-hardening the steel or iron of which it is made, so that any shiny or light metal, 47, of about the size of the window 48, would as readily indicate the safety of the gun when seen through the window as though the word Safe could be read. Furthermore, the light-colored metal 47 is also very soft in comparison with the steel of the tang surrounding it and causes a great saving of stamping-dies used to imprint the word Safe therein.

4f) represents one hammer having a forward arm provided with an anti-friction roller, 50, which is engaged by the lower arm of the mainspring' 51. This spring is kept in place by means of the lower tang-plate, 30, and a screw, 52, which passes through the side IOO IIO

of the frame and projects across the spring- This makes a very effective and cheap spring, and it is held in place by parts required for other purposes, the screw 55 serving also as the pivot or fulcrum of the cooking-lever 53. This lever and the hook 56, which removably engages itwith the barrels, are claimed in a former patent, No. 381,088, to me, and its operation need not be here described; but in Figs. V and VII I have shown means whereby the fore-arm when in place keeps thehook engaged with the levers or with the barrels, according as the hook is adapted to engage the one or the other.

57 represents a sliding pin, here shown as made in two sections, each slotted or cut away at one side to engage screws 58 in the lug 19 of the barrels, and 59 is a spring acting between thenr f5() is a studiixed in the fore-end 62 to engage the end of the forward section of the pin 57. When the gun is closed, the stud 60 presses the pin 57 back against the upper end of the hook 5U and forces it into engagement with the cross-bar 63, and the spring 59 permits such freedom of motion as may be required of the hook to keep it enga-ged when in service. Yhen the fore-end 62 is removed, the pin 57 is at liberty to slide freely with its spring 59 either way, and the hook 56 is no longer held into engagement, and it will be removed freely from the lever 53 by the act of removing the barrels from the fra-me, as

described in the aforesaid patent.

6l represents the common cartridge-retractor finger secured to the. frame ll, and it requires to be bored through to permit the passage of the stud (50. In the modification shown in Fig. VII the hook is permanently hung at its lower end to the levers, and the upper end is free to be unhooked from the barrels when not pressed on by the spring-pin 57.
