2 Claims.

The present invention relates to improvements in firearm structures and relates more particularly to means for absorbing recoil shocks between the receiver and the complemental stock 1. of a given firearm.

One of the objects of the present invention is to provide a firearm structure having a superior construction and arrangement of parts whereby the connection of a receiver and a stock is of such character as to minimize or eliminate the splitting of the stock occasioned by recoil shocks or stresses incident to the discharge of the firearm.

Another object of the present invention is to provide a superior firearm construction wherein means is provided adjacent the receiver-cavity in a stock for holding the walls of such cavity or recess from spreading under recoil stresses and without requiring the use of transverse screws or the like.

With the above and other objects in view, as will appear to those skilled in the art from the present disclosure, this invention includes all features in the said disclosure which are novel over the prior art and which are not claimed in any separate application.

In the accompanying drawings, in which certain modes of carrying out the present invention are shown for illustrative purposes:

Fig. 1 is a view of the central portion of a firearm structure embodying the present invention and shown partly in side elevation and partly in vertical central-longitudinal section;

Fig. 2 is a horizontal sectional view taken on the line 2-2 of Fig. 1;

Fig. 3 is a transverse sectional view taken on the line 33 of 1;

Fig. 4 is a broken view in vertical central-longitudinal section of the central portion of the stock;

M Fig. 5 is a top or plan view thereof;

Fig; 6 is a view in side elevation of the triggerplate member detached;

Fig. 7 is a top or .plan View thereof; and

Fig. 8 is a broken underside view of the re ceiver-member detached. together with a portion of the barrel.

The particular firearm herein chosen for purposes of illustrating one form which the present invention may assume. comprises in the main a stock Ill, a receiver-unit H and a barrel l2. The stock H3 is pre erably made of wood or other suitable heat-insulating material and the receiver-unit H, in the instance shown, comprises a receiver-member l3 and a trigger-plate memher l4. Both of the members I3 and I4, as well as the barrel l2, are preferably formed of highgrade steel.

The two complemental members l3 and Id of the receiveror frame-unit ll may be secured together in any suitable manner such, for instance, as by providing the receiver-member IS in the lower portion of its hollow interior with a pair of longitudinally-extending coupling-ribs I5-l5 laterally spaced apart and projecting respectively inwardly toward each other from the respective opposite side-walls of the member it, as is especially well shown in Fig. 3. Resting respectively upon the upper surfaces of the coupling-ribs lli-l5 just referred to are couplingribs l$lfi projecting outwardly respectively in opposite directions from the opposite sides of a lug ll upstanding from the trigger-plate member l4 about midway the length thereof.

The lower portion of the receiver-member l3 and the major portion of the trigger-plate member I4 is normally accommodated in a vertical longitudinal recess l8 formed in the stock Ill before referred to, and intersecting both the upper and lower surfaces thereof.

It will be noted by reference to Fig. 5 in particular that the vertical recess 18 in the stock It] is wider at its forward portion than it is at its rear. At the junction of the narrow and wide portions of the recess l8, each of the side-walls is formed with two forwardly-facing recoil-seats l8l9 respectively located adjacent the respective opposite sides of the recess l8. Inwardly of each of the seats is, the material of the stock is extended forwardly beyond the vertical plane of the adjacent recoil-seats 9 to provide a stabilizing-rib or lip 28, one of which latter is located adjacent each of the recoil-seats Ill-l9, and which act in a manner as will hereinafter appear to stabilize the respective opposite sidewalls of the recess H3 in the stock U3.

The trigger-plate member l4 before referred to of the receiver-unit H, is relatively narrow transversely at its rear portion and relatively wide at its forward portion to fit the respective narrow and wide portions of the vertical recess H3 in the stock Ill. The said trigger-plate member is provided adjacent its rear end with a depending guard-loop 2i housing the finger-piece of a trigger 22. The rear portion of the trigger plate member It also mounts a firing mechanism which, however, requires no detailed description herein other than possibly to note that the said firing-mechanism includes a hammer .33, a sear 24 and a hammer-sprin 25.

The relatively-wide forward portion of the trigger-plate member M is provided with a vertical magazine-receiving passage 26 adapted to receive a box-magazine (not shown) in a manner well known in the firearm art. On each of its respective opposite sides and about midway of its length, the trigger-plate member I4 is provided with one of two corresponding stabilizing-ribs or lips 21. Eachof the stabilizing-ribs 2'! just referred to, projects rearwardly and overlaps the outer face of the adjacent one of the stabilizingribs 20 of the stock I 0, as is especially well shown in Fig. 2. Preferably, therear face of each of the stabilizing-ribs 21 of the trigger-plate mem ber l4 bears'against the adjacent one of the forwardly-facing recoil-seats 19 of the stock I0.x Preferably also, the forward face of each of the spects as illustrative and not restrictive, and all changes coming within the meaning and equivalency range of the appended claims are intended to be embraced therein.

I claim:

1. A firearm structure including in combination: a stock having an interior vertical longitudinal recess therein which is relatively wide at its forward end-portion and relatively narrow at its rear end-portion, the said stock being formed in each of the opposite side-walls of the said recess at the junction of its two said end-portions with one of two vertical stabilizing-ribs each'having an outwardly-facing surface; a receiver-member extending into the upper part of the recess in the said stock; a trigger-plate member having a relatively-wideforward end-portion and a relativestabilizing-ri-bs of the stock lfl also engages a with the rear face of the adjacent wide front portion of the trigger-plate member, Hi to assistiin absorbing recoil shocks,

The central lug ll of the trigger-plate member I is formed centrally at a point above the coupling-ribs |6'l6 thereof, with an abutment-rib 28 having its forward face normally in engagement with the rear face of. an integralweb 29' extending transversely across the hollow interior of the receiver-member 13 adjacent the lower end and'aboutmidway the length thereof.

The respective rear portions of the members I73 and I4, may, if desired,rbe coupled to the stock In in a suitable manner such, for instance, as the manner shown in my co-pending application Serial No. 473,11 filed January 21, 1943.

C When the firearm is discharged, the receivermember I3 will, of course, violently recoil under the shock and such recoil will be transmitted to the trigger-plate member I4 by way of the web 29 of the receiver-member f3 and the abutmentrib 28 of the trigger-plate member 14. The recoil shocks thus received by the trigger-plate f member 14 will, in turn, be transmitted by the rear faces of the stabilizing-ribs 2'i--2l and the adjacent portions of the trigger-plate member M, to' the stock In. I

When the recoil shocks are received by the stock Win the manner'as above'described, there is a natural tendency for the relatively-thin sidewalls of the vertical recess I8 in the stock Ill, to

spread laterally outwardly and eventuallyjto weaken the stock and cause the splitting thereof, unless such tendency is ofiset. The outward flexing of the side-walls of the recess I8 is prevented or so minimized as to be substantially harmless,

by the engagement of the inner face of each of the stabilizing-ribs 21 of the trigger-plate member M with the outer face of the adjacent one of the two stabilizing-ribs 2B of the stock Ill.

By means of the present invention, the tendency of the'stock to split under the shock of recoil strains its overcome or minimized without requiring the use of special bindingor couplingscrews or the like-passing laterally through the stock.

Thus, not only is the cost of such bindingscrews-obviated, but more space is left free in thefirearm structure for the accommodation of various features of the firearm mechanism, magazine, etc.

The invention may be carried out in other specific ways than those herein set forth without departing from the spirit and essential characteristics of' the invention, and the present embodiments are, therefore, to be considered in allre-- ly-narrow rear end-portion respectively extending into the lower parts of the respective forward and rear end-portions of the recess in the said stock, the said trigger-plate member being formed on each of its respective opposite sides at the junction of its relatively-wide forward end-pore said trigger-plate member and'constructed' and arranged to transmit the rearward recoil shock of the said receiver-member to the said triggerplate member.

.2. A firearm structure including in combination: a stock having an interior vertical longi-' tudinal recess therein which is relatively wide at its forward end-portion and relatively narrow at its rear end-portion; the said stock being formed ineach of'the opposite side-walls of its saidrecess at the junction of its two said end-portions with one of two vertically-extending and forwardly-proje'cting stabilizing-ribs each having an outwardly-facing surface; a receiver-member extending into the upper part of the recess in'the said stock; a'trigger-plate member having a relatively-wide forward end-portion and a relativelynarrow rear end-portion respectively extending into the lower parts of the respective forward and rear end-portions of the recess in the said stock,

the said trigger-plate member being formed on each of its'respective opposite sides at the junc-f tion of its relatively-wide forward end-portionand its relatively-narrow rear'end-portion with one of two vertically-extending and rearwardly projecting stabilizing-ribs, each of, the last-mentioned stabilizing-ribs having an inwardly-facing surface engaging with the outwardly-facing surface of the adjacent one of the said vertical and forwardly-projecting stabilizing-ribs of the said stock to thereby hold the side-wallsof the recess in the said stock against undue outward fiexure; and coupling-means coupling the said receiver-' member to the said trigger-plate member and constructed and arranged to transmit the rear' ward recoil shock of the said receiver-member to the said trigger-plate member,
