My invention relates to that class of firearms that are commonly supported at arms length with the butt resting against the shoulder when being red, and an object of my invention, among others, is to provide a rearm of this class that shall be particularly simple in construction as well as effective in operation, the simplicity of construction enabling the firearm to be produced at an exi@ tremely low cost.

Oneform of rearm embodying my invention and in the construction and use of which the objects herein set out, as well as others, may be attained, is illustrated in the accompanying drawings in which- Figure 1 is a view in side elevation of my improved rearm with the front end of the brrel and the back end of the stock broken o ga Figure 2 is a similar view, scale enlarged and with parts broken!V away in centrai lengthwise section, the mechanism being shown as cocked.

Figure 3 is a view similar to Figure 2 but showing the tiring mechanism in its uncooked condition.

Figure 4 is a view in horizontal lengthwise section through a portion of the firearm on a plane passing through the axis of the barrel,

` tlie upper end of the magazine being broken Figure 5 is a detail side view of the guard. Figure 6 is a bottom view of a portion of the receiver and the action yoke.

Figure 7 is a detail isometric view of the breech block.

Figure 8 is an isometric view of the front end of the receiverlshowing the action yoke projecting therefrome In the accompanying drawings the nuvmeral 10 denotes the frame or receiver of my improved firearm that is formed of any suitable material. This receiver has a groove of uniform depth extending from end to end thereof, the opening of said groove being on the under side of the receiver. This enables the receiver to be produced in a very simple and inexpensive manner. l

The trigger guard 11 1s also formed of U- v shape in cross-section, it being composed of 'thereof to the outside and underneath the any suitable metal that is, in a manner similar to the receiver, grooved from end to end enabling it to be formed in a very economical manner. It is of a width substantially the width of the groove in the receiver into which groove it its and is secured in any suitable manner, as by means of rivets or screws. Lugs 12 are formed on the side pieces of the trigger guard, these lugs being secured to the receiver in the groove therein. A block 13 is secured within the groove in the receiver at the front end thereof, rivets or screws being employed for the purpose of securing said block in place, and a barrel 14 is secured in an opening in the block in' a e: manner common to firearm construction, as

herein shown screw threads bein employed for securing the barrel to the blocli. A stock `15 of any suitable material is secured to the rear end of the receiver or frame in any suit- 7 able manner, as herein shown a bolt 16 extending through the stock from its rear end and engaging a block 17 secured in the rear end of the groove in the trigger guard, and as shown in Fi re 2 of the drawin s.

A breech olt 18 is mounted or sliding movement in a breech bolt chamber 19 constituted b the bottom of the groove in the receiver, t e front end of the chamber being closed by the block 13 and the rear end by the lugs 12 and the stock 15. The breech bolt has an action lug 20 at its rear end projecting from its under side, said lug having shoulders to rest upon the upper edges of the side parts of an action yoke that in turn rests upon the utpper edges of the sides of the trigger guard or slidlng movement thereon. A groove 21 is formed in the bottom of said lug to receive a in 22 connecting the rear ends of the brano es 23 of said action yoke, which yoke comprises a cross piece 24 at the front end thereof uniting said branches. The action yoke extends from within the chamber 19 through suitable openings at the front barrel 14 said openings being formed b reducing the width of the lower part o th block 13 thereby locating shoulders on said block spaced from the upper edges of the sides of the trigger guard and asshown in 13u Fig. 8. A forepiece is secured to the front end of the frame or receiver in any suitable manner and a spring supporting rod 26 projects into the end of said forepiece and through a hole in the cross piece 24 of the 'action yoke and into the block 13. An action spring 27 is supported on said rod and thrusts against the cross piece 24 at its front end and against a pin 28 extending through the rod at its rear end, and as shown in Fig. 6 of the drawings.

A magazine 29 is insertable into a magazine chamber through a hole in the bottom of the trigger guard and within the breech bolt chamber 19. A magazine catch 30 of any suitable construction may be employed to engage a notch in the front edge of the magazine to hold it in place.

A hammer 31 is pivotally mounted between the side parts of the trigger guard and is urged forward to its striking position as b'y means of a spring 32 mounted on a firing rod 33 pivotally attached to the rear end of the hammer and extending backwardly through the block 17, and as shown in Figure 3 of the drawings.

A sear 34 is pivotally mounted between the side parts of the trigger guard and is of pe,

culiar construction, having an angular recess 35 in its side within which a disconnector 36 is located. This disconnector is pivotally attached to the upper end of a trigger guard, extending forwardly in line with the sear and then being bent around the sear and extending through the recess 35 and upwardly therein. The upper end of the dis'- connector is positioned to engage within a notch 37 in one of the branches of the action yoke, and as shown in Figs. 2 and 3 of the drawings, when said yoke is in its forward position. When thus engaged in said notch the bend in the disconnector will engage the back edge of the sear and a pull upon the trigger will thereby disengage the sear from the hammer. When, however, the action yoke is in its rearward position, as shown in Fig. 2, the disconnector is forced downwardly and the bend therein will not engage the back of the sear if the trigger be pulled, and it will therefore at this time be impos' sible to disengage the sear from the hammer. The sear is thrust toward the hammer by means of a sear spring 39, the upper back edge of the sear being shaped with an edge to engage notches in the hammer in a manner common to firearm construction generally. The disconnector 36 is forced upwardly by means of a disconnector spring 40 and t-he trigger is forced forward by a trigger spring 41.

The breech bolt 18 has grooves 42-43 formed in opposite sides thereof, a firing pin 44 being located in one of said grooves and an extractor 45 being located in the opposite groove. The firing pin and extractor co-operate in extracting a cartridge shell in a mannercommon to firearms of prior construction, and as shown in Fig. 4 of the drawin s. In this structure, however, a tail 46l is ormed extendinglaterally from the back end of said pin and a spring 47 is arranged to exert its force against the beveled end of the extractor 45 and against the tail 46, as shown in Fig. 4, for the purpose of normally holdin the firing pin in its rearward position an for normally forcing the extractor in position to engage its nose with the .rim of a cartridge shell, the spring 47 therefore serving a doui ble function.

It will be noted that by thus constructing the parts the firing pin may be stamped out from a flat piece of metal as may also the ex" tractor and the formation of the grooves in.

the breech bolt'to receive these flat elements greatly simplifies the construction both of t-he means in the breech bolt for receiving the elements and in the structure of such elements.'

It will sbe noted that throughout the entire structure I have made use of parts that are formed from flat metal and that the openings in different members are grooves which may be readily made at a minimum expense within the members in which said parts are i to be located.
