EMIL RITTER VON SKODA, OF PILSEN, AUSTRIA-HUNGARY.

BREECH-LOADING ORDNANCE.

SPECIFICATION forming part of Letters Patent No. 458,505, dated August 25, 1891.

Application led October 4. 1889. Serial No. 325,987- (No model.) Patented in September 11, 1888, No. 192,922; in England September l1, 1888I Switzerland November 15, 1888, No. 64; in Italy January 8, 1889,

February 15, 1889,No. 36,730, and No. 522.

To all whom it may concern.-

Be it known that I, EMIL RITTER voN SKo DA, a subject of the Emperor of Austria, re-

siding at Pilsen,in the Province of Bohemia,

in the Empire of Austria Hungary, have invented certain new and useful Improvements in Breech-Loading Guns, (for which I have obtained Letters Patent in Austria-Hungary, No. 36,730, and No. 522, dated February 15, 1889; in Germany, No. 47,362, dated September 11, 1888; in France, No. 192,922, dated September' 11, 1888, and Additional Patent No. 192,922, dated November 20, 1888; in England, No. 13,142, dated September 1l, 1888; in Belgium, No. 83,911, dated November 12, 1888; in Switzerland, No. 64, dated November 15, 1888, and in Italy, Reg. Gen., Vol. XXII, No. 24,486, and` Reg. Att., V ol. XLVIII, No. 119, dated January 8, 1889;) and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon,which form a part of this'speciiication.

Referring to the drawings, Figure 1 is a side elevation of so much of a gun as is neoessary to illustrate my invention, a portion of lsaid gun in rear of the breech being broken away to show the breech-block and a portion of the actuating mechanism therefor. Fig.2 is a view similar to Fig. 1, a portion of the breech-block being also broken away to show the central cartridge way or channel thereof, said breech-block being shown in its position when the breech-chamber is open. Figs 3 and 4 are views similar to Figs. 1 and 2, the breech-block being therein shown in axial vertical section on the line 1 1 of Fig. 5, the firing-pin in Fig. 3 being shown as released Fig. 5 is a section on line 2 2 of Fig.

The invention relates to that class of guns known as rapid-firing guns, in which center or rim re metallic cartridges are used, and in the drawings and in the following description the invention is shown and will be Germany September 11, 1888,1To.47,362;in France No. 13,142; in Belgium November 12, 188B, No. 83,911; in XXII, 24.486, and XLVIII, 119, and in AustriaHnngary described in relation to the former class of cartridges.

The invention has for its 'object to increase the rapidity of tire, in that the movements of the breecl1blockthat is to say, what is called vthe "breech-action -is so constructed as to be operated with great speed, and in that the firing-pin is controlled by the movements of the breech-block in bringing it to a full-cook. To these ends the invention consists, essentially, in the construction of the breechaction or breech-block actuating mechanism also in the combination, with the firing mechanism and breech-block, of devices for automatically controlling` the firing-pin through the movements of the breech-block to bring the said pin to a full-cock, and, lastly, in structural features and combinations of parts substantially as hereinafter described, and as set forth in the claims.

In the above-described drawings, B indicates the breech end of the gunbarrel,n which is formed a vertical slot b. Near the rear end of slot b are formed guidegrooves l), Fig. 2, for the guidance of the breech-block A, that is provided on opposite faces with tongues or ribs cl, that fit into said grooves Z). The breech-block .Alias a straight vertical rear face and two faces as als, inclining rearwardly from a front straight vertical face that is provided with the striking-plate a. In its upper face in the plane of the axial line of the gun-barrel the breeelrblock has a semi-cylindrical recess a2, Figs. 2 to 5, that forms a guide for the insertion into the breech-chamber of a cartridge when thel link D, fulcrumed to the breech-block at ctt, as shown in Fig. l.

The relative arrangement of the lever C, arm c', and link D is such that when the breech-block A is in a position to close the breech and the lever C in the position indicated in full lines in Fig. l the axis of c and the axes of the pivotal connections between c and D and between the latter and the breech-block will not lie in a straight line; but, on the contrary, the axis of the pivotal connection between o and D will lie outside and in front of a line intersecting the axis of c and that of the pivotal connection between the link D and breech-block A. The arm and link thus form such an angle as to firmly support the breech-block against accidental motion within its chamber, such as might result from the recoil of the gun. be readily understood that the breech-block is not at the limit of its vertical movement when the lever reaches the position shown in full lines in Fig. l, said block reaching this limit before the lever C reaches the limit of its` movement, the breech-block moving slightly downward, again reaching its proper position to close the breech when the lever C has reached the limit of its motion, the reverse taking place when the breechblock is moved to open the breech-that is to say, when the lever is moved into the position shown in dotted lines in Fig. 1 the breech-block moves slightly upward during the first portion of the movement of lever C, then downward, under the action of arm c and link D, to the position shown in Fig. 2.

The movements of the breech-block A are limited by a stop E in the left-hand wall of the breech-block chamber, said screw projecting into a vertical groove c5, Fig. 5, in the lateral face of the breech-block.

A spindle F, that has its bearings in the breech-block, carries withinthe central Vertical recess a of said block a lever f in4 perpetual engagement with a shoulder g2,'forined on the head of the firing-pin G, Figs. 3 and 4, and within the recess a3 of the' breechblock the said spindle carries a radial arm or lever f', that is held in contact with the link D by the spring g of the firing-pin exerting its power on the lever f on said spindle F when said firing-pin is not cocked. When the firing mechanism is therefore in the position shown in Fig. 3 and the breech-blockactuating mechanism in the position shown in Fig. l-that is to say, in the positions said mechanisms assume immediately after the firing of the gun-and the lever G is moved fromright to left, the breech-block A will rst rise slightly as the arm c and link D straighten out, then as the links move into the position shown in Fig. 2 the lever or arm f Will be rotated, thereby rotating the spindie F and lever f from right to left, forcing the firing-pin in the saine direction to a point at full-cock, in which it is automatically locked by the arm 71. of a sear H, engaging a It will therefore locking-shoulder.7L12 on the hub of leverf, (see Fig. 4,) the arm h of sear H being heldin permanent engagement with a shoulder on a trigger J by means of a spring h2. The relative arrangement of the arm f and link D is such that as the breech-block moves down the said arm f is depressed to a greater extent than is necessary to insure the engagenientof the Sear-arm h with the full-cock shoulder f2, so that what is termed an over-cock is here provided, as in all other percussion-locks. During the last portion of the downward movement of the link D the arm-ff will rise again slightly, remaining in constant contact with said link. In closing the breech, should the sear become accidentally disengaged from the shoulder f2, the firing-pin would not be' suddenly thrown forward by its spring g, owing to the fact that the radial-arm f is held in Contact with the link D by said spring,so

that the motion of the firing-pin will correspond with the motion of the link, and will therefore move forward gradually instead of suddenly, thus' preventing injury to the liring-pin. As'stated above, the radial arm f is depressed to a greater extent than is necessary to its engagement with the sear; but should by accident such engagement not take place at the time it can take place when ythe lever C is moved from the position shown in Fig. 2 to that shown in Fig. l, for the reason vthat the radial arm f, as the lever is moved,

is again depressed to such an extent as to permit the arin h of the sear to engage the notch f2. In view of the fact that the arinf is in contact with the link D until theA breechblock has reached a position to nearly close the breech-chamber, at which time. said link moves away from thc said arm, which had been tilted or depressed during the downward movementof the breech-block and locked into position by the Sear, it follows that the. liring-pin cannot be released until said link has left the arm, or when the breech-chamber is closed.

As shown, the ring-pin G is arranged within a perforation in the b reech-block, the outer end of which is closed bya perforated screwplug g', that serves as a guide for the pin G, the ends of the actuating-spring@ bearing against said plug and against the head of the firing-pin, respectively. l

The shell-extractor K consists of two levers or radial arms 7c on a transverse spindle K', said radial arms having at their upper end a recessed portion k2, Fig. 2, for the rim of the cartridge-shell. The spindle, on which the extractor-arms 7c are formed or to which they are secured, is also provided with a short radial arm k3, that lies in the path ot the breech- IOO IIO

IIS

as the recess d2 in the breech-block comes opposite the breech the arm k3 will also have reached the shallowest part of the groove d3 and the cartridge-shell will be thrown out.

In loading' the gun the cartridge is inserted so that its rim lor flange will lie in the recesses k2 of the extractor-arms lo', as shown in dotted lines in Ifig. 2, and as the breech-block moves up 'to close the breech the inclined face as of the block moves the cartridge fully into the breech-chamber.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-
