BREECH-LOADING GUN.

SPECIFICATION forming part of Letters Patent No. 341,751, dated May 11, 1886.

Application filed March 15, 1886.

.To all whom it may concern.-

Be it known that I, Dinnnnion W. JANSEN, a citizen of the United States, and a resident of Joplin, in the county of Jasper and State of Missouri, have invented certain new and useful Improvements in Hammerless Breech-Loading Guns; and I do hereby declare 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 to make and use the saine, reference being had to the accompanying drawings, which form a part of this speciiication, and in which- Figure 1 is a perspective view of my improved breech-loading hammerless gun. Fig. 2 is a view of the upper side of the gun. Fig. 3 is a view of the under side of the gun. Fig. 4 is a view of the upper side of the gun, showing the lock-casing opened. Fig. 5 is a longitudinal vertical sectional View of the gun. Fig. 6 is aperspective detail view of the trigger-plate and the triggers removed from the gun. Fig. 7 is a longitudinal sectional view of one of the lock-chambers. Fig. 8 is a view of the gun with the barrels removed and the lock and barrel seat removed and shown above the stock, and Fig. 9 is a perspective detail View of the guard and its bolt with the eccentric disk.

Similar letters of reference indicate corresponding parts in all the figures.

This invention relates to breechloading guns in which the hammers are concealed; and it consists in the improved construction and combination of parts, as will be hereinafter more fully described, and pointed out in the claims.

In the accompanying drawings, the letter A indicates the stock, which may be of any suitable construction, and which is formed with a recess, B, in its upper side for the reception of the lock and barrel seat D. The rear end of this seat is provided with a block, Gr, the rear face of which is formed with a heavy upwardly-pointing hook, E, which engages a recess, F, shaped for its reception in a block, G, having a rearwardly-projecting curved tongue, H, which is secured to the upper side of the stock by means of a screw, I.

The barrels J J are connected in the usual manner, and are provided near their breech Serial No. 195,190. (No model.)

ends with a downwardly-proj ecting perforated tongue, K, which is secured in the recess Lin the stock by means of a pin, M, passing through the stock and through the recess and perforation of the tongue. rlhe breech ends of the barrels rest upon the forward end of the seat, which is thus held in place by them atits forward end, while the rear end is held in place by the hook at its rear end. The side of one of the barrels is provided with a long cylindrical eye, N, through which passes a long pintle, O, the forward end of which is provided with a head, P, which bears against the forward end of the eye, and the rear end of the pintle is inserted through an eye, Q, projecting from the side of the block at the rear end of the lock and barrel seat, where it is provided with a nut, R, which bears against the rear end of this eye.

A tube, S, is secured to the side of one of the lock-casings, T, which are shaped similarly to the barrels,and fill the space between the breech ends of the barrels and the block at the rear end of the seat, and this tube turns' wardly-projecting outer end, W, of an arm,

X, projects into this slot. The arm slides below the forward end of the lock-seat, and has the lower end of a pin, Y, secured to its inner end, which pin slides in a longitudinal slot, Z, in the forward end of the lock-seat.

The portion A which connects the barrels is formed with a groove, B', in its under side, corresponding to the longitudinal slot, and a bar, C', slides in this groove and has a cartridge-extracting lip, D', projecting upward from its rear end, portions of the said lip projecting into the breech ends of the barrels and forming portions of the cartridge-seats at the said ends of the barrels. rllhe twist of the slot in the tube of the lock-casings is such that when the lock-casings rest in their seat the pin in the slot and the extractor will be in its forward position, the lip of the extractor resting in its notches in the breech ends of the barrels, and when the lock-casings are swung out to the side the pin will be forced rear- ICO Q @4197er ward, drawing the arm and extractor rearward with it, throwing out the empty shells from the breech ends of the barrels.

The outer lock-casing, or the casing which is not hinged, is provided with a laterallyprojecting lip, E,which projects out th rough a notch in the edge of the lock-seat, and the said easing is also provided with asmall notch or recess, F', to the rear of the lip, into which notch the inwardly-projecting stud G upon the free end of a fiat spring, H', secured to the block of the lock-seat, may project, holding thelock-casings in place when they are turned down in their seat, and allowing them to be tilted out to the side when the lip upon them is engaged.

The lock-casings are tubular, and havelongitudinal slots I in their under sides, extending from the rear ends to slightly past their 2O middles, and screw-threaded caps J t in the forward screw-threaded ends of the casings, and are formed with central perforations, K, the rearends of which expand. Coiled sprin gs L fit with their forward ends upon the rear reduced and screwthreaded portions, M', of the screw-caps, and the rear ends of these spl'ings lit upon the forward reduced and screw-threaded ends, N of two blocks, O', which fit and slide within the lockcasings.

These blocks are formed with axial perforations P', in which slide the smooth inner portions of two screws, Q', which are provided with small coiled springs R', wrapped around them and placed between their heads and the rear ends of the blocks, while the forward screw-threaded ends of the said screws fit into axial screw-threaded perforations S in the rear ends of the firing-pins T. The reduced forward ends tit into and may project slightly 40 through the perforations of the screw-caps. Pins or sears U project from the sliding harn mer-blocks through the slots in the lock-cas ings, sliding in the same.

The rear end ofthe bottom of the lock-seat is formed with two longitudinal slots, VV, which register with the slots in the lock-casings, and the forward ends of these slots are formed with enlargements XV toward the free side of the lock-casings, allowing the sears to enter the slots when the casings are tilted into the lockseat.

The trigger-plate X is secured to the under side of the gun stock, and is formed with an upwardly-projccting post, Y', through the upper end of which passes a pin, Z', having its ends projecting at both sides of the post. The upper ends of the triggers A are pivoted ppon the ends of this pin and project forward,while the rear or lower portions, B, of

6o the triggers are bent at right angles, or nearly so, to the upper portions and project downward through longitudinal slots C in the trigger-plate, one trigger projecting down slightly behind the other, so that each trigger may be drawn without disturbing' the other.

rlhe forward ends of the triggers are formed with upwardly-projecting lips D", beveled at their forward faces, so that the lower beveled ends of the sears may be drawn over the said lips and thereupon be engaged by the same, the forward ends of the triggers having springs E forward of their fulcra, which springs force the lips of the triggers upward.

A shaft, F", is journaled with its upper end, which is provided with a nut, G, in the lockseat at the forward ends of the longitudinal slots between the same, the nut bearing against the upper side of the said seat, and immediately below the under side of the seat this shaft is provided with a round disk, H seO cured to the shaft by a lip, l, projecting from its periphery, and this disk or arm is capable of being turned with the shaft to both sides toward the beveled lips of the triggers. The lower end of the shaft projects through the forward end ofthe trigger-plate, being journalcd in the same, and the forward end of the trigger-guard J is secured by means of a nut, K", to the said lower end. The rear upwardly and forwardly curved end, L, of the said guard is formed with apcrforation, M, which may fit over around stud, N, projecting from the rear end of the triggenplate, so as to hold the guard in its position, the springiness of the metal in the guard forcing the perforation upon the stud and allowing it to slip off from the stud when the guard is drawn 4to either side.

It will now be seen that when the guard is turned to one side, and thereupon to the other side, the disk or round arm, which projects forward when the guard is in its normal position, will be forced against the ends of the sears, which project down through the slots in the lock-casings and in the lock-seat, and the sears will be forced back sufficiently against the springs of the hammer-blocks to engage the lips of the triggers, which will hold them back cocked. W'hen now the triggers are pulled, lthe sears and hammer-blocks will be drawn forward by the springs, and the impetus given to the blocks land the firingpins by these springs will cause the firing-pins to ily out through the perforations inthe screwcaps, striking the fulminate orcap of the cartridges, which have been inserted into the barrels, and firing them, whereupon the small spiral springs between the heads of the screws in the rear ends of the liring-pins will draw the said screws back, and the firing-pins with them, drawing the forward ends of the firing-pins into the perforations of the screwcaps, so that the lock-casings may be tilted out by the lip upon them turning with the tube upon the hinge-pintle. This opening of the breech end of the barrels by turning the lock-casings will cause the cartridge-extractor to be forced rearward, drawing the empty shells with it, and the gun may be reloaded and the firing-pins and blocks cooked by means of the guard and the round disk or arm after the lock-casings have been closed down into the seat.

It follows that the barrels may be rifled or smooth, as may be desired, and that the mechanism may as well be'employed to a singlebarreled fire-arm as to a double-barreled firearm as long as the principle remains the same, and various changes may be made in the construction of the several parts, as well as por` tions of the mechanism may be used in connectionwith portions of other similar mechanisms without departing from the spirit of my invention.

The triggers and the sliding ham nier-blocks, with their downwardly-projecting sears, may be used with different means for forcing the blocks back, and hammer-blocks with downwardly-projecting sears may be used with different firing-pins, and all such changes maybe made in the construction of the mechanism without departing from the general principles of the mechanism.

The coiled spring at the rear end of the tube, which projects from the lock-casings and is hinged upon the pintle, serves to allow the lock-casings to be moved slightly rearward while being closed, for the purpose of yielding to any slight obstruction which might be met with from the inserted shells in the breeclles of the barrels, or to enable the lock-casings to yield if the cartridge extractor should meet with resistance in withdrawing the cartridgeshells.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United Statesl.
