To all whom it may concem: I

Be it known that I, THOMAS C. JOHNSON, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in One-Piece- Stock Takedown Firearms; and I do hereby declare the following, when taken in connection with the accompanying drawings and the characters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this application, and represent, in a Figure 1, a view in right-hand side ele= vation of a fire-arm embodying my invention.

My invention relates to an improved onepiece stock take-down firearm, the object being to provide a simple and convenient arm constructed with particular reference to provision for throwing the recoil and the counter-recoil upon the stock and so protecting the take-down screw from strain.

With these ends in view my invention consists in a one-piece stock take-down firearm characterized by having a recoil-collar mounted upon the receiver and isolated from the barrel, and by certain details of construction and combinations of parts as Wlll'bQ hereinafter described and pointed out in the claims.

In carrying out my invention as herein shown, I employ a recoil-collar 17 having a depending recoil-taking lug 18, an upwardly-projecting si 'ht-projection 19 and internal threads 20, which latter receive the responding external threads 21 of a stem 22 located at the forward end of the receiver 23 and separated therefrom by a stop-shoulder 24, whereby the said collar is mounted upon the forward end of the receiver rather than upon the barrel 25 of the arm as has heretofore been proposed. The rear or recoil face 26 of the In 18 of the collar is located in the plane 05 the rear face thereof, while the forward face of the lug is beveled as at 27 to facilitate the assembling of the arm.

For the reception of the recoil-collar 17 which in the preferred form, is larger in diameter than the body of the receiver, the one-piece stock 28 is formed with a transverse groove 29 corresponding in width to the width of the said collar. The rear shoulder 30 of this groove coacts with the rear face of the collar in taking up the recoil, while the forward shoulder 31 of the groove coacts with the forward face of the collar in taking up the counter recoil.

and centrall For the reception of'the recoil-taking lug 18 of the collar, the stock is formed with a recess 32 leading out of .the bottom of the groove 29. The rearwall of the said recess coacts withthe recoil face 26 of the lug in taking the recoil.

The stem 22 of the receiver is formed with internal threads 33 which receive responding threads 34 formed 'upon the stem 35 of come in contact with the forward face ofthe collar, whereby the barrel is guarded against being deformed by any tilting tendenc of the collar at the time of recoil.

or fastening the receiver 23, the collar .17 and the barrel 25 to the one-piece stock 28, I employ a take-down screw 37 having a slotted and knurled'head 38, a threaded end 39, and a circumferential groove 40, which latter receives a retaining-rin 41. For-the. reception of the screw 37 emloy a take-down bushing 42 having-a anged head 43 and retaining-threads 44, this screw being forced or screwed into a hole 45 entering the lower face of the stock intersecting the recess 32 formed therein for the rece tion of the re coil-taking lug 18 as descri ed. The stock is also formed with a recess 46 concentric with the hole 45 for the reception of the flanged head 43 of the bushin and the knurled portion of the head 38 o thescrew 37. The bushin is rovided at its outer end with threa s 4 responding to the threads of the threaded end .of the screw 37 and permitti the take-down screw to be passed throug the bushing 42, after which the retaining-ring 41 is fitted into the circumferential groove 40 of the screw. The ring then coacts with the threads 44 to prevent the screw from drop ing out of the bushing which is also provi ed with a counter-sink 48 and a slot or kerf 49.

The recoil-taking lug 18 is formed with a threaded screw-hole 50, the threads of which respond to the threads'of the threaded end 39 of the take-down screw 37 As the screw 37 is turned home into the lug 18,

the lower faces of the receiver 23 and bar-- rel 25 are firmly seated upon the bottom of the semicircular groove 51 formed in the stock 28.

Under the construction described, the recoil of the arm falls entirely upon the recoilface 26 of the lug 18 and the rear face of the collar, the former bearing against the rear face of the recess 32 in the stock and the latter bearing against the rear shoulder of the barrel in w 30 of the groove 29 in the stock. The tend-' ency of the collar 17 to tilt under the shock of the recoil, is reduced to the minimum by the engagement of the rear face of the recoil-collar with the shoulder 30 of the groove 29, whereby the recoil-taking suraces are carried u ward toward the axis hieh the recoil is generated. Moreover, by mounting the recoilcollar directly upon the receiver instead of upon the barrel as has been done before the tendency of the collar to tilt is resisted by the relatively heavy receiver rather than by the relatively light barrel, which is thus protected against deformation. On the other hand, the counter-recoil is entirely taken up by the impingement of the forward face 0 the collar upon the forward shoulder 31 of the ove 29 in the stock. Therefore, the entire shock of recoil and the entire counter-recoil is removed from the takedown screw 37, upon' which no transverse strain is thrown. Incidentally, the collar is concealed within the stock except as to its up er portion, whereas in the guns of the prior art, the lug'has been made of the same diameter as the stock, thus necessitating the use of a two-piece stock in which no provision can be made for taking the counter recoil by the stock itself.

The si ht-projection 19 of the collar 17 lifts the ine of sightjabove the heated barml and virtually takes the lace of a ventilated sight-rib which is and cumbersome. However this sig t-projection will only be used when my invention is embodied in shot-guns as herein! shown, m invention being equtll a 'plicable to ri es as I would have it c ear y understood. v

In Figs. 13 to 15 inclusive I have shown a modified construction in which the recoilcollar 52 corres nds to the collar 17 except in so far as it 15 secured to the receiver b means of a locking-pin 53 passing throu -a transverse ove 54 in the stem 5510f t 0 receiver 56.- n this case, the stem 55 is not provided with external threads nor is the collar rovided with internal threads.

In 1g. 16 another modification isshown, in which the collar 57 and the receiver 58 are of the same external diameter, there being no groove in the stock to receive the collar 57; the recoil will be taken entirely by the lug (not shown) of the collar.

My improved gun, broadly viewed, comprises a one-piece stock-unit, and a rigid receiver-and-barrel unit, the latter bein separable as one piece from the said stoc -unit and provided with a recoil-taking collar the faces of which coact directly with the faces of the stock so as to take the shocks of the employed to secure the receiver-and-barrel th ex 've unit and the stock-unit together is prevented from being hammered and deformed by the shocks of recoil and counter-recoil.

I claim:

1. In a onepiece stock take-down firearm, the combination with a one-piece stock, of a receiver, a recoil-collar mounted thereupon and transmitting the shocks of recoil directly to the said stock, and a barrel rigidly mounted in the receiver without contact with the said collar, whereby the barrel is protected against injury.

2. In a one-piece stock take-down firearm, the combination with a one-piece stock having a transverse groove, of a receiver, a recoil-collar mounted thereupon and entering the said groove and coacting directly with the walls thereof to take the shocks of recoil and the counter-recoil, and a barrel rigidly mounted in the receiver without contact with the said collar, whereby the barrel is protected against injury.

3. In a one-piece stock take-down firearm, the combination with a one-piece stock having a recess leading out of the bottom thereof, of a receiver, a recoil-collar mounted thereupon and formed with a de ending recoil-taking lug the rear face 0 which engages with the rear wall of the said recess;

and a barrel rigidly mounted in the receiver without contact with the said collar, whereby the shocks of recoil and the counter-recoil are transmitted by the said collar di-v coacting directly with the one-piece stock to take the shocks of recoil and the counter-recoil and making no contact with the said barrel; and fastening means mounted in the stock and engaging with the said collar for securing the receiver to the stock, whereby the shocks of recoil and the counter-recoil are transmitted by the collar directly to the one-piece stock and whereby the said barrel and fastening means are protected from injury.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
