IMPROVEMENT IN BREECH-LOADING FIRE-ARMS.

Specification forming part of Letters Patent No. 208,889, dated October 15, 1878; application filed April 5, 1878.

To all whom t may concern:

Be it known that I, JOHN D. OOON, of Centreville, in .the county of Lake and State of Colorado, have invented certain new and useful Improvements in Fire-Arms, and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it appertains to make and Ause the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specifica-tion, and in which- Figure 1 is a top view vof my improved lire-arm with its breech closed. Fig. 2 is a similar View, showing the breech open. Fig. 3 is an elevation of the same. Fig. 4. is a detail view of a spring-bolt used for locking the breech. Fig. 5 is a bottom view of the same. Fig. 6 is a vertical central longitudinal section ot' the nre-arm in the line .fc x of Fig. l. Fig. 7 is a vertical longitudinal 'section in the line y y of Fig. 1. Fig. 8 is a detail view ofthe shell-extractor turnedbottonl upward. Fig. 9 is a section in the line z z of the same. Fig. 10 is adetail view of the muzzle-portion of my fire-arm, and` Fig. 11 is a front view of the same.4 l

This invention relates to improvements in breech-loadingre-arms; and consists in the construction and combination of parts, as hereinafter more fully described and claimed.

In the drawings, A represents a gun-barrel fastened or screwed to a breech-frame, B, of gutter shape. The front part b of the frame B is at the top provided with hinges c, to which a breechblock, C, is attached. The breech-block C has at its rear end a straight slide, D, with an inclined face, d, and a tension-spring, d1. A transverse pin, E, having a square portion, e, is inserted into the breechblock O below the slide D, and has an arm, c', fitted onto its square portion, which arm opcrates the slide by means of a notch, d2, in the side of the slide, the notch being of such shape that the arm c operates the slide without lost motion. The ends of the pin E are provided with thumb-levers F, which are inserted into the sides of the breech-block so as to enter the breech-frame B with it. The said thumb-levers have concentric shields f, which pass over the broken corners of the breechblock and over the rear ends of the ring-pins G of the gun, so that when the thumb-levers F are pushed forward the ends of the firingpins are covered by the said shields, and when the thumb-levers are left to themselves the shields are down and off the said firing-pins, leaving their ends exposed. Thus, in locking the breech-block, if the slide D is not completely moved back into its retaining-notch in the breech-frame B, the thumb-levers F are not in their normal position, and the shields j' cover the ends of the firing-pins G and prevent the hammers H of the gun from accidentally operating them. The tiring-pins Gr are of square shape, soas to prevent them from turning, and they have needle-points g' snugly'ftted in the forward end of the breechblock, and they are also provided in a cavity, c, of' the breech-block with retractor-springs, which keep the points g within the breechblock and the rear ends of the firing-pins within the range of the hammers H. The breech-block O is provided with a cam-plate, I, which operates a spring-catch, j, of a sliding frame, J, suitably inserted into the bottom of the breech-frame B. To the sides of the frame J two semi-cylindrical carriages, jl, are attached, which are provided with hooks jz at the front corners. The said hooks are diametrically opposite each other, and take hold of the rims of the inserted cartridges at two opposite points, so that even when the cartridgeease should lit tightly into the gun-barrel, it will not jam while being extracted, as is often the case when the extracting-hook only takes hold at one side of the cartridge-shell. The forward end of the frame J is provided with a tension-spring, js, suitably fastened in the stock of the gun, whereby the carriages jl are kept against the breech ends of the gun-barrels.

The remaining parts of the fire-arm maybe necessary to describe.

Operation: When the gun isftofbe loaded the operator pushes the thumb-levers F forward and swings the thereby unlocked breechblock O over toward the muzzles of the gun.

The cam-plate I is thereby swung backward, and pushes the spring-catch j before it, whereof ordinary construction, which I do not deem by the frame J and the carriages j are a-lso moved back, causing the hooks jL to extract the cartridge-shells from the barrels. B y holding the muzzles of the gun up the extracted shells slip down in the carriages jl and are easily removed therefrom. Before the breechblock is swung` quite back the cam-plate I leaves the sprin g-cateh j, and the frame J, with the carriages j, is moved forward into its old position by the spring j. Fresh cartridges are now inserted into the breech ends of the barrels, and the breech-block C is moved down again. The straight part of the cam-plate I comes now in contact with the spring-catch j, pushes it aside, and finally passes it, the spring-catch then resuming its former position. Previous to this operation, and during the same, the hammer H must be in the safety or iirst rest, as shown in full lines in the drawings.

When the gun is to be tired the breech-block C must be in its normal position, and the bolt D must be fully back in the retaining-notch in order that the shields f do not cover the ends of the firing-pins Gr. The hammer is moved into the second rest and the gun discharged, which is effected by the hammer striking the ring-pin G and driving the needleend g into the cartridge, thereby exploding the fullninate and the powder therein.

Having thus described my invention, what I claim as new, and wish to secure by Letters Patent, is-

lhe combination of the breech-block C, having cam-plate I, and the shellextractor Jy`1j2, having tension-spring j and spring-catchy, substantially as set forth.

In testimony that I claim the foregoing as my own I hereunto afx my signature in the presence of two witnesses.
