Letters Patent No. 114,259, dated May 2, 1871.

IMPROVEMENT IN BREECH-LOADING FIRE-ARMIS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may conce/ru Be it known that L'HEINRICH BCHNER, of the city, county, and State of NewYork, have invented anew and improved Breech-loading-Fire-Arm; and I do herebydecla-re that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification, in which- Figure l represents a side view of my. improved re-arm without barrel and butt end.

Figure 2 is a longitudinal section, of the same.

Figure 3 is a detail .side view of the spring-tube and breech-block.

Figure 4 is a detail plan or top view of the lock.

Figure 5 is a detail side view of the same, showing the opposite face from that which is illustrated iu Similar letters of' reference parts. Y y

My invention relates to breech-loading lire-arms, and consists in certain improvements thereon, which will be fully described in connection with all that is indicate corresponding necessary to a full understanding thereof, and then.

clearly pointed out in the claim.

A in the drawing represents the stock of the fire-A arm.-

B ist-he barrel, rigidly connected therewith.

C is the cartridge-block, being a vertically-adjustable hlock fitted against the breech end of the barrel, and bored to form the caltridge-chamber a.

The block C can be elevated so that the chamber a will be clear above the upper face of the barrel to permit the inserti-onl of the cartridge, and it is then lowered to bring the chamber a in line with the bore of the barrel for the projectile.

D is the breech-block of the arm. It isl made of strong material, and secured iu the frame of the gun ls)o as to lit iiush against the back of the cartridgelock.

I prefer to make itremovable inthe manuel' shown-'- that is to say, provide it with Aa flange, b, which overlaps and abut-s against the front end of the stock at c, and with a hook-shaped recess or projection, which permits the spring-tube and needle-case E to lock into it in the manner clearly shown in fig. 3. In this manner a substantial breech-block is provided ou needle breech-1oaders.

permitting the proper discharge of The spring-tube E is fitted into the frame or stocki of the gun behind the breech-block.

It contains a sliding plug, F, from which the needle G projects, and a spring, H, behind said plug for propelling it toward the cartridge.

The back end or head d of the tube E I prefer to make -longitudinally adjustable within said tube for the purpose of regulating therebythe power of the spring, and for allowing to throw'said spring entirely out of action, by so far withdrawing the head as to prevent its compression by the inner plug F.

The functions to be performed by the arm are,

therefore, the following: The ca irtridge-blo'ck must be elevated, as in fig. 2, to permit the insertion of the cartridge; the plug F must be pushed and held back for compressing the spring and withdrawing the needle; the cartridgeblock must then beY lowered to bring the cartridge in line with the bore ofthe barrel and, finally, theplug is released and propelled forward bythe spring to carry the needle toward the cartridge and explode the charge'.

From the cartridge-block C projects downwardly au arm, e, which has a lug' or knob, f, at. its lower end.

This lug or knob enters an inclined slot which is provided on a slide, I.

The slide I is, by a link, g, connected with the crank h of 'a transverse shaft, J, which` hangs in the lower part of the gun.

fiis the crank-handle of the shaft J, by means. of which the same may be turned at will.

The slide I hasvprojecting pins, jj, which enter straight horizontal slots in a guide-plate, l, that projects from the bottom plate .or guard m.

The slide is moved horizontally by the turning of the crank-shaft J, and its motion serves to move the block C vertically.

A hook, a, projecting from the slide I, catches against a/lug, o, of the plug F.

When the handle t is turned so as to move the slide I backward the block O is elevated, and at the same time the plug F is moved back so as to compress the spring H, all parts being then in the posivtion shown in fig. 2.

In this position the'triggerL catches into a notch, p, of tbe plug, and serves to retain the same.

After the cartridge has been inserted inthe block G, the shaft J is turned to move the slide forward, thereby lowering the block O to bring the cartridge in line with the barrel.

The cartridge-block has a projecting flange or ledge, r, on top, whereby its downward motion is absolutely defined. f

u The touch of the trigger will release the plug and produce the discharge of the cartridge.

. The cartridges employed are preferably of such construction. that their shells will be ejected at the same time with the projectile, so that separate means for ejection after firing need uotbe provided.V

Whenever the head is drawn out, as i`n iig. 3, the spring will not be compressed by theplug, and the arm is, therefore, at rest .without danger of spontaneous or accident-nl discharge.

The motions for operating this gunlare very fewiirst, the crank-handle is tilrned hack; second, the cartridge inserted; third, the 'crank-handle turned forward; and, nally, the trigger touched. The breech-block D keeps the back of the cartridgechamber properly closed, and prevents the escape of gases intothe lock.v

Having thus described my invention, -I claim as new A'and desire to secure by Letters Patent- '1. The slide I, combined with the vertically-reciprocating cartridge-block C and with the horizontallyreciprocating needle-head or plug F, to operate the same simultaneously', as specified.

2. The crankshaft J, connected with the slide 1 scribed, in successively withdrawing, holding, and dis-1 charging the needle-plug F.
