NIT'ED S'rA'rns IMPROVEMENT IN REPEATING FIRE-ARMS.

Specification forming part at Letters Patent No. 11,375, dated January 26, 1864.

To all whom it may concern:

Be it known that I, JOSHUA GRAY, of Boston, in the county of Suifolk and State of Massachusetts, have invented a new and useful Improvement in Repeating- Rifles; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference be ing had to the accompanying drawings, forming a part of this specification, in which- Figure 1 represents a longitudinal section in a plane parallel with one side of the breechpin, showing a side elevation of the same and its appendages; Fig. 2, a side view of the carrierblock, and Fig. 3 a front view of the same.

"The nature of my invention consists, first, in moving the breech-pin F both at right angles and parallel with the barrel by means of a curved stationary rack, N, engaging with a small pinion, M, actuated by a sector-pinion, G, both pivoted to the breech-pin; second, in the use of a carrier-block, L, front end of the breechpin F, and actuated by means of a spring cartridge-carrier bar, 0, and a lever, J to which lever motion is communicated, at the proper time, by means of a on the sector-pinion G; and, third, in the employment of a spring-bar, O, for the purpose of carrying up the cartridge from the magazine O'to the barrel, as hereinafter described.

To enable others skilled in the art to make and use my invention, I will now proceed to describe its construction and operation. A is the stock. B is the barrel. 0 is the cartridge-magazine, of any desirable length, directly under and parallel with the barrel B. D is a lever, turning on the fulcrum d in a suitable slot in the stock, the end of said lever being bent at rightangles to it, and entering the magazine 0, as shown in the drawing, for the purpose of stopping the front cartridge from leaving the magazine until required.

E is a spring, by means of which the end of lever --l) is pressed up into the magazine, as shown in the drawing, said lever D being thrown out of the magazine at the proper timeby means of the bar 0, as hereafter explained.

F is the movable breech-pin, shape of which are shown in the drawing Fig.

sliding on the.

' block L is capable of the size. and

pin F ascends, the. cartridge,

1, and its thickness in Fig. 2. The lower half of F is about one-eighth ofan inch thinner than the rest, forming a shoulder, (represented by the dotted line 40,) the object of said shoulder being to prevent the'breech-pin F from coming out otthe slot Q, in which it slides, by coming in contact with the cleat y. F is also prevented from rising up too far by means of a similar cleat, Z. (Shown by dotted line in Fig. 1.)

G is a sector-pinion, fast to the guard-lever I, and turning on the pivot H, which is screwed 'into the pin F.

M (the size and relative position of which is l a small pinion turning on.

shown in Fig.1) is the' 'pivot m, which is'screwed into the pin FL N is a rack, confined to the stock by screws. parallel with The longer part of this rack is the body of the stock, the shorter part, a, being at nearly a right angle with the stock A, as represented in Fig. 1.

Thus, the cogs of the pinion M, engaging with those of the rack N and sector G, it is obvious that by turning the latter by means of the guard-lever I the breech-pin F will be moved first downward. parallel with the part a of the rack, and then along the part parallel with the body of the stock, or vice versa.

L is the carrier-block, the shape of whichis shown in Figs. 2, 3, and 4, the part l, Fig. 4, moving in a groove in the breech-pin F. This sliding up and down on the end of the breech-pin about one-halt of an inch. When pressed barrel B, to close the same, flush with the top of scends, the spring-bar O,(the free end of which passes through the slot 1, Fig. 3) will force L up so as to project about half an inch above F. J is a bent lever, turning on the fulcrum b, one end of said lever passing through slot-s, Fig. 3, in carrier L, the opposite end projecting over the sector Gr, so as to come in con tact with the start 9 when the lever I is thrown down from the stock toward the barrel sufficiently far, by means of which the spring-bar 0 will be forced down beyond the end of the magazine 0 and against the lever l), forcing the latter out of the inagazine and allowing a cartridge to drop into the space between the carrier L and the barrel. .Then,as the breechresting on the the top of L is against the end of the F; but as the latter deend of O, will be carried up opposite the berrel B, ready robe forced into the sa'me altv the proper time, being prevented from rising too" high by means of the spring P, which passes over the center of the breech-pin, as shown 'by the dotted lines inFig. 1.

Having thus described the construction and operation of my inventionywhat' I claim as new, and desire to secure by Letters Patent, 1s 1 The stationary curved rack N, constructed and operating as described.

2. The spring-bar O,for the purpose of carrying up the cartridge from the megaz'ineto the barrel, substantially as described.

' i 3. The sliding carrier L, in combination with the lever J and spring 0, or their equivalents,

--asend for the purpose described.
