Application filed Decemberlfi, 1856. Serial No.221,593. (No model.) Patented in France March 2, 1886, No. 161,833; in Belgium March "2, 1886. No. 53,252; in England March 12, 1886, No. 3,543, and in Brazil March 13, 1886, No. 334.

To aZZ whom it may concern:

Be it known that I, ATHANASE GnUoHU, of Bahia, Brazil, have invented new and Improved Breech-Loading Fire- Arms, (for which Letters Patent have been granted by the following countries, vizz Brazil, No. 334, dated March 13, 1886; France, No. 161,833, dated March 2, 1886; Belgium, No. 53,252, dated March 2, 1886, and England, application No.

3,5i3, March 12, 1886,) of which the following is a full, clear, and exact description.

My invention relates to an improvement in breech-loading fire-arms, and has for its ob ject to provide a quick, simple, and convenient means for loading, firing, and extracting the cartridge-shell from the barrel, and wherein, by the upward movement of a hand-lever pivoted to the breech-block, the hammer and operative parts contained in said breech-block will be positioned for firing, and by a continued lateral movement of said block in the shoe the old shell will be extracted, admitting a speedy insertion of a loaded shell, and wherein, further, although the breech-block be again carried to its normal position within the shoe, the hammer and operative parts be ing still positioned for firing, the hammer cannot be tripped by the trigger until the aforesaid hand-lever is carried down again to its first position.

The invention consists in the construction and combination of the several parts, as will be hereinafter fully set forth and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of a rifle having my improvement applied, partly in section, illustrating the position of the operative parts in dotted lines immediately after firing. Fig. 2 is a plan view of the same illustrating the breech-block carried out from the shoe partly in section, the operative parts positioned for firing, also showing the detachment of the trigger from the hammer. Fig. 3 is a longitudinal horizontal section, on line 00 w of Fig. 1, through the shoe, the breech being removed. Fig. 1 is a transverse vertical section on line 31 y of Fig. 1; and Fig. 5 is a side elevation,

partly in section, of the breech-block detached. Fig. 6 is a transverse vertical section on line 2 z of Fig. 2, and Fig. 7 is a section taken on line a a of Fig. 6. Fig. 8 is a transverse vertical section on line o o of Fig. 3, and Fig. 9 is a forward end view of the breech-block shown in Fig. 5.

In the application of my invention I attach, by screws or otherwise, to the stock 1 and barrel 2 a shoe, 3, which shoe is provided with a recessed portion, 4, upon the right-hand side, as shown in Fig. 1, and an opposite curved upper central edge upon the left-hand side, as shown in Fig. 2. \Vithin the said shoe, centrally the top, I also provide a recess, 5,while at the base, upon top the shoe, to the left, an L-shaped slot, 6, is cut, in which slot, at its upper end, is pivoted, at 7, a similar-shaped latch, 8, provided upon the inner face of its short arm with a spring, 9, and upon its upper face with a grip, 10.

Centrally in the shoe, upon the under side, a trigger, 11, is pivoted, the said trigger being provided in the upper rear edge with a notch, 12, and from the outer left-hand side of the shoe 3, near its under edge, a slot, 13, is cut, (shown in Fig. 4,) through which slot an angle-lever, 14, is entered from the outside and pivoted, as illustrated in dotted lines, Fig. 3. The short arm 15 of the said lever 1 1 is adapted to extend transversely through the shoe, engaging in its passage the notch 12 in the trigger, and the said short arm is provided upon its inneredge, near the angle of thelever, with a notch, 16. The upper end of the longitudinal arm of the said lever 14 is provided with a rounded inwardly-proj ecting head,17,adapted to extend within the shoe 3 a short distance within a recess, 18, in the bottom of said shoe, immediately over said head, whereby it is exposed to View from the interior, as shown in Fig. 3, for a purpose hereinafter set forth. The entire angle-lever 14 is actuated in one direction by a spring attached thereto and bearing against the wall of the lever-recess, the tendency of this spring being to retain until otherwise acted upon the short arm 15 in contact with the trigger, so that the said trigger may not be operated. A breech-block, 19, is now provided, adapted to fit into the shoe 3 in a longitudinal direction, so that in operation it may be moved a quarter-turn laterally, the said breech-block being also adapted to contain internally the cocking and firing mechanism. About centrally the upper forward end of the block 19 an integral pin, 20, is formed, adapted to enter the upper end recess, 5, in the shoe, the body of the said breechblock being made of a contour best adapted to fill the recessed shell of the shoe, while the rear portion of the block is provided with a tubular shank, 21, having a beveled end, 22, the said shank being less in diameter than the width of the block, with its under side in substantially the same longitudinal plane with the under side of said block, the sides of the shank and block being ordinarily made continuous.

The breech-block is readily entered in position within the shoe by raising the pivoted catch 8 with the left hand, while with the right the shank of the block is entered the lower tubular portion, 23, of the shoe. The pin 20 is then entered into the recess 5 and the catch again closed in its slot, the spring 9 thereupon pressing against the beveled end of the shank, holding the block securely in place. The spring now acts as a pivot for the shank end of the block, the said pin 20 constituting the pivot for the forward end. Thus the block may be turned outward to the right easily and at pleasure, and as readily extracted from the shoe by simply raising the pivoted catch 8. About centrally of the breech-block, near the forward end thereof, apin, 24, isjournaled, to one end of which pin, projecting through the right-hand side of the block, a hand-lever, 25, is secured, adapted, when in its normal position, to extend longitudinally in the direction of the barrel and rest in ashield, 26, made in tegral with the side of the shoe. Within the breech-block, upon the journaled pin 24, a three-armed lever, 27, is keyed by a screw, 28, extending transversely through said-lever and pin, as shown in Fig. 2. Each of the said arms a, b, and c has a separate function, which will be hereinafter stated.

To the upper and outer right-hand side of the breech-block 19 aspring, 29, is secured by ascrew, '30, which spring, extending at an angle downward, is provided at its lower end with a knob adapted to travelin a semicircular groove, 31, cut in the under face'of the hand-lever 25, to one side of and above the lever-connection with the pin 24. The said groove is formed with recesses at each end, whereby the said hand-lever is held in either a horizontal or vertical position, as desired, and illustrated in Fig. 1.

About centrally of the upper edge and forward end of the breech-block 19, andin alignment with the center of the barrel, when the said block is in its closed or normal position, a recess, 32, is made about the diameter of an ordinary firing-pin, having an enlarged inner portion, 33. Into this recess 22' the point of a firing-pin, 34, is inserted, provided at asuitable distance from its point with an annular flange, 35, adapted to have play in the enlarged inner recess, 33, and find abearing upon the shoulder formed by reason of the two connecting recesses 32 and 33 when the pin has been projected for firing. The inner end of the firing-pin 34 is provided with an annular head, 36, a space intervening between thesaid head and the annular flange 35.

To the rear and slightly below the pin 24 a second pin, 37, is journaled transversely in the breech-block 19, having keyed thereon,within said block, a hammer, 38, having a centrallyconcaved front edge, 39, teeth 40 cut in its lower edge, and a curved guide-arm, 41, integral with its upper rear edge, adapted to engage the inner top surface of the block 19 to steady the movement ofsaid hammer. A downwardly-curved integral arm, 42, is also provided the rear edge of the hammer located about centrally of the guide-arm 41, and the base of the hammer having pivoted thereto a roller, 43. 4

Within the beveled end 22 of the tubular shank 21 of the breech-block a screw, 44, is inserted, adapted to extend up parallel with one side and attached thereto. The said screw is provided at the end of the shank 21 and below the head of the screw with a curved recess, 45, into which the bent end of a U shaped spring, 46, is made to rest, as shown in Fig.5. One member, 47, of the said spring, as shown in Fig. 2, is made to bear against the roller 43, attached to the hammer, while the other member, 48, is made to bear against the upper side of a pawl, 49, pivoted within the breech-block, the forward end of which pawl is adapted to engage the teeth 40 in the hammer 38, while the other end, having a slight rounded projection, 50, (shown in Figs. 1, 2, and 5,) is adapted when the breech-block 19 is in its normal position to rest upon the upper surface of the trigger 11.

Within the upper portion of the shoe,in diagnal alignment with the base of the barrel 2,an

extractor, 51, is pivoted in a recess made to receive it, the said extractor being provided with a semicircular upper portion,71, adapted to partially encircle the barrel-orifice intervening between the rim of the cartridge and the barrel. The under portion of said extractor is centrally projected and provided with a recess, 52, as shownin Fig. 8. Through this centrally-projected portion of the extractor and its recess 52 a pin, 53, is passed at an incline from the outer right-hand side ofthe shoe (see Fig. 1) into the inner solid portion, 54, thereof,. as shown in Fig. 8. A spring, 55, is now entered through a slot, 56, cut in the shoe below the head of said pin 53, as shown in Fig. 1, one end being secured by a screw, 57, near the lower edge of the right-hand side of the shoe 3, the said springibeing provided with an upper angular portion, 58, adapted to project inward and upward, as shown in Fig. 7, engaging the outer face of the lower projection of the extractor, and also bearing against the under face of a lever, 59, pivoted inthe recess 52 of the extractor by its pivotal pin 53. The said lever is more or less triangular in form. The upper end,beingmoreorlesshooked, engages the upper curved surface of theextractor, while the inner edge, 61, is made to project beyond the normal plane of the extractor and travel in a semicircular groove, 62, cut centrally in the outer edge of the breech-block 19, the said groove having at one end, centrally situated therein,a pin, 63, which pin is adapted as the breech-block is carried outward laterally to engage the inner end, 61, of the lever 59, and in its passage bear the said lever down, causing the hooked end 60 thereof to turn quickly backward the extractor upon its pivot and thereby extract the shell 64., the spring 55,after the pin has passed the lever, restoring the extractor to its normal position (see Fig. 7 and retaining it in place, likewise the lever 59, until again acted on by the pin 63.

The operation of the gun is as follows: Atter having been fired, as shown in Fig. 1, the hand-lever 25 is carried upward from a horizontal to a vertical position, as shown in dotted lines, same figure. By this movement of the hand-lever 25 the parts are positioned as shown in Fig. 2that is to say, the rollercarryingarm a of the three-armed lever 27 carries the hammer back to a cooked position,

compressing the spring 46 in the shank of the block between the roller upon the hammerarm 42 and the pawl 49, now in engagement with the notches 40, at the base of said hammer. Simultaneously with the above movement of the arm a the hooked arm b engages the annularIc-ap 26 of the firing-pin 34, carrying it back into position for firing while the lower arm, 0, is withdrawn from the slot 18 in the shoe and engagement with the lever 14, pivoted in said shoe, whereupon the short arm of said lever is carried back to its normal position, locking the trigger. Thus all danger of premature firing is avoided. The operative mechanism remaining in the position above described, the breech-block 19, containing said mechanism, is by means of the said hand-lever 25 carried over laterally to the right. The pin 63 in the groove 62 of said block in the passage thereof engages the angular lever 52, which, operat-' ing upon the extractor in manner described, throws out the old shell. A new cartridge being inserted, the breech-block is returned to its normal position within the shoe. When ready for firing, the hand-lever is carried down to its normal or horizontal position within the shield 26, the roller-carrying arm a-and the hooked arm I) of the three-armed lever 27 being carried forward out of contact with the hammer 38 and firing-pin 24, while the lower arm, 0, of said lever is simultaneously carried down to a contact with the shoe-lever 14, causing the notch 16 in the short arm of said lever to register with the trigger-arm, leaving the said trigger to trip the hammer by engagement with the enlarged lower end, 50, 0f the pawl 49.

It will be seen from the above that when the hand-lever is in a vertical position, although all the parts are positioned for firing, no communication is had between the said parts and the trigger, but that when the said hand-lever is placed horizontally no obstruct-ion to immediate firing is offered. Itwill be also observed that all the operative parts, which are few in number, are contained in the breech-block, and that when desirable for cleaning or other purposes the said breech-block may be quickly and readily removed from the shoe, and, therefore, from all connection with the arm.

My invention is equally as applicable to pistols as to rifles.
