Application December 3, 1935, Serial No. 52,672

16 Claims. (.Cl. 42-69) My invention relates more particularly to that class of firearmsl which are supported against the shoulder in the act of ring, and an object ofr my invention, among others, is the production of a iirearm of this type that shall be simple in construction, particularly efficient in operation, and one that may be produced at a minimum cost.

One form of a firearm embodying my invention and in the construction and use of which l the. objects herein set out, as well as others, may be attained is illustrated in the accompanying drawings in which Figure 1 is a side view of my improved firearm.

l Figure 2 is a similar view but looking at the opposite side of the device.

Figure 3 is a detail View on enlarged scale in central vertical section through the stock, the parts in the center being shown in full.

.Figure 4 is a view similar to Fig. 3 but with the inner parts also cut in central lengthwise section.

Figure 5 is a bottom view of the receiver with the parts located thereon, the rear end of the barrel being shown and the stock being removed.

Figure 6 is a similar view but showing the parts removed from the receiver.

Figure 7 is a bottom view of the same parts in a lengthwise horizontal plane passing through the axis of the barrel.

Figure 8 is a view in cross section on a plane denoted by the dotted line 8-8 of Fig. 4.

Figure 9 isla view in section on a plane denoted by the dotted line 9 9 of Fig. 4.

.3 In the accompanying drawings the numeral I5 denotes the stock of my improved firearm, I6 the receiver and I1 the barrel secured to the receiver in any suitable manner'. The rear end of the barrel is seated in a groove in the stock 1n .i0 a manner common to devices of this class, and it is secured in place as by means of a screw I8 through the under side of the stock and engaging a lug I9 having a dovetail shaped end engaging a dovetail shaped groove formed crosswise of the 45 barrel, and as shown in Fig. 3 of the drawings.l 'I'he receiver is a tubular piece of metal having a bore 28 of uniform diameter extending entirely through it forming a breech bolt chamber which is closed at its rear end as by means of a cap 2| Il which may be screwthreadedly engaged with the inner walls of the chamber. A breech bolt 22 is located for reciprocating movement in said chamber and a breech bolt closing spring 23 extends into a hole in the rear end of the breech bolt, a

55 breech bolt strut 24 extending into said hole for a short distance and backwardly therefrom, its opposite end being seated in a recess in the cap 2I. A firing pin of any ordinary type is located in the breech bolt for contact with cartridges 25 located in the breech of the barrel I6, and as 6 shown in Fig. 4 of the drawings.

An action housing is secured to the under side of thereceiver, said housing being located in a. chamber 26 in the stock I5. This housing is of inverted trough shape `and comprises a base 21 10 and sides 28. fastening 'screws being passed through the base and threadedly engaged with the under side of the receiver, the outside of the base being curved to t the curved under surface of the receiver. u

A hammer 29 is pivotally mounted upon a pin supported in the sides 28, and a hammer strut 30 is pivotally secured at one end in a notch in the hammer. said strut supporting a hammer spring 3| which thrusts at one end against a shoulder* 20 on `the strut and at its opposite end against a retainer 32 which is secured within the housing 21 projecting from the front end thereof and having its end bent downwardly and notched to receive the strut 3B and as shown in Fig. 4 of the 25 drawings. One of the screws which secures the housing 21 to the receiver may also be employed for securingr the retainer 32 in place. A stop lug 33 projects forwardly from the lower end of the hammer to engage against the inner part of the 30 base 21 of the housing to limit the backward movement of the hammer.

A seai- 34 is pivotally mounted on a pin sup-A ported in the sides 28 of the housing, said sear being spring pressed with its lower edge into en- 35 gagement with a. notch in the hammer 29, said sear having a notch 35 to receive a lug 36 projecting from one side of a disconnector 31 pivotally mounted at its rear end on the trigger 38.

A disconnecting lip 39 extends upwardly from the 4c front end of the disconnector into position to engage the rear end of the hammer strut 30 which operates, when the hammer is thrust forward by its spring, to disconnect the lug 36 from the notch 35. A spring pressed plunger 40 en- 45 gages the disconnector to press it normally upward for engagement of the lug 36 with the notch 35.

The trigger 38 is pivotally mounted in the sides 28, the trigger being spring actuated to force the nger piece 4| normally forward. A magazine 42 of any ordinary form and construction is employed to support cartridges for delivery into the breech of the barrel by the action of the breech bolt in a manner common to devices of this class, and a magazine catch of any desired form may be employed for releasably holding the magazine in place, such catch being shown at 43 in Figure 4. The spring which acts upon the disconnector forms arest for a plunger 40 s eated upon said spring, said parts being located in a hole in the trigger and said plunger is thrust against a lip 44 projecting laterally from the lower edge of the disconnector 31, and as shown in Figure 4 and in dotted lines in Figure 5 of the drawings. Said lip projects into a hole extending laterally into the trigger and overlies the end of said plunger, thereby effecting pressure up-` wardly on the disconnector. v A firing pin 52 of at shape is located in a slot extending longitudinally along the side of the breech-bolt and as shown in Figure 4 of the drawings.

An extractor- 45 of any ordinary form is secured to the side of the breech bolt to withdraw the cartridges from the barrel and against an ejector 46 also of common construction. A cooking handle 41 is secured to the breech bolt and projects outwardly through a slot 48 extended from the ejecting opening 49 in the' side of the receiver and as shownin Figs. 3 and 7 of the drawings.

The disconnector is pivotally attached to the trigger by means of a pin 50 which projects on opposite sides of the trigger. One end of this` pin abuts one side 28 of the housing to retain-the trigger against lateral movement within 'said housing. The disconnector is pivotally mounted on the opposite projecting end of said pin.` A breech bolt stop 5I is employed for limiting backward movement of the breech bolt.

Inaccordance with the provisions of the patent statutes I have described the principles oi operation of my invention, together with the device which I now consider to represent the best embodiment thereof; but I desirev to have Ait .understood that the device shown is only illustrative and that the invention may be carried out by other means and applied to uses other than those above set out.
