Specification of Letters Patent.

Application filed Ma; 3, 1909. Serial No. 493,563.

To all whom it may concern:

Be it known that I, THOMAS C. JOHNSON,

- 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 specification, and represent, in

Figure 1 a, broken view in side elevation of a tubular magazine take-down firearm constructed in accordance with my invention, the handle being shown in its normal position, 2'. 6., the position which it has preparatory, to its .retractionfor opening the gun as well as preparatory to being shoved forward for taking the gun down. Fig. 2 a broken view of the gun partly in side elevation and partly in vertical longitudinal section of the gun-barrel and magazine as detached from the receiver or gun-frame or taken down,. showing. the handle .at the limit of its forward movement or inits take-down position in which it is frictionally held so as to hold the magazine and the action-bar in their take-down positions. Fig. 3 a view in vertical section on the line ab of Fig. 1, showing the handle in its normal position. Fig. 4 a corresponding View onthe line 0-65 of Fig. 2, showing the handle and magazine in their take-down positions and therefore at the limit of their forward movement in which they are frictionally held. v

My invention relates to an improvement in tubular magazine take-down firearms of that class in which the mechanism of the gun is operatedby. a sliding handle having a rearwardly extending action-bar which is detachably connected. with the mechanism of the 'un when the gun is assembled. In guns of this class it is desirable to provide for holding the magazine and handle at the extreme limit of their forward movement or in their so called take-down positions so that the rear end of the magazine and. the rear end of the action-bar may be held entirely clear of the receiver to facilitate screwing the barrel into and unscrewingit therefrom.

The object ofmypresent invention is to provide improved means of extreme simplicity for holding the handle and magazine in these so called take-down positions.

Vith these ends in view my invention consists in a gun having certain details of construction and combinations of parts as will be hereinafter described and pointed out in the claims.

In carrying out my invention as herein shown, I employ a wedge-like holding cam 2 which I locate upon the lower face of the gun-barrel 3 at a point to one side of the longitudinal center thereof. The said cam 2 is formed at one side of its center with a cam-face & which is engaged by an inclined face 5 forming one of the, side walls of a transverse slot 6 in the upper edge of an annular cap or ferrule 7 applied to the forward end of the wooden handle-grip 8 of the sliding operating-handle which is provided with a sheet-metal reinforce in the form of a shell 9 which extends throughout the length of the grip and rides upon the tubular magazine 10. The upper face of the handle-grip 8 is formed with a deep longitudinal groove 11 located in line with the slot 6 in the cap 7 to permit the grip 8 to fit over the lower face of the gun-barrel 3. The rear end of the reinforcing shell 9 receives a sheet-metal sleeve 12 brazed or otherwise secured in place and provided at its rear end with an annular flange 13 enteringatrecess 14 in the rear end of the handle-grip 8. The said sleeve also provides for the attachment to the sliding handle of the rearwardly extending actionbar 15 adapted at its rear end in the usual manner for connection with the action-mechanism of the gun which is located within the gun-frame or receiver 15 At its rear end the barrel has interrupted threads 16 which provide for its attachment by a quarter turn 1 to the receiver the forwardv end of which is formed with a socket l6 having corresponding interrupted threads. The rear end of the sliding tubular magazine 10 is also provided with corresponding interruptedthreads 17 by means of which it is secured by a quarter turn to the receiver which is also provided with a socket 1O having corresponding interrupted threads. Ne'ar its rear end the barrel is furnished with a fixed band or yoke 18 the depending lower portion of which has an opening 19 supporting the rear end of the magazine which slides back and forth through the said opening, the band 18 being also provided with a transbar 15 slides back and forth. The opening 18 corresponds in cross-sectional form to the Z cross-sectional form of the bar, but is sufficiently larger than the same to permit the, free movement of the bar back and forth At its forward end the m aga-. zinc is supported in a clip 20 depending through it.

from the barrel 3 to which it is secured by a clamping-screw 21. At its forward end the magazine is furnished, as shown, with a transversely arranged longitudinally movable pin 22., forming a handle for the rotation of the magazine in being turned the quarter turn required for screwing it into the 71'6- ceiver and unscrewing it therefrom.

To limit the forward movement of the sliding handle in the normal operation of the gun, I locate upon the magazine 10 a stop in the form of a collar 23 and .a spring in the form of a split-ring 2i encircling the magazine at a point just to the rear of the said collar with which it engages. The said collar 23 and spring 24 are properly placed upon the magazine for the engagement of the rear edge of the spring by the forward edge of the sleeve 12 aforesaid just before the handle reaches its so called normal position,

whereby the handle is stopped as by .a buffer,

and without undue shock to the hand of the user or to the gun. The magazlne 10 is also provided with a stop-lug 25 which engages with the rear face of the clip 20 so as -.to

limit the forward sliding movement of the.

magazine when the .same is detached at its rear end from the receiver whereby the rear end of .the magazine is prevented from being drawn forward out of the band or yoke 18.

hen the gun is assembled, the rear end of the action-bar 15 is connected in the usualmanner with the action-mechanism contained within the gun-frame or receiver 15 and the handle is prevented from moving forward of its normal position in which it is shown in Fig. 1 by the engagement of the sleeve 12 with the spring 24 and collar 23. This position is called its normal position because it is from this position that it is retracted to operate the mechanism of the gun for opening the gun.

Preparatory to taking the gun down, the magazine 10 must be rotated a quarter turn by the pin 22 so as to disengage its interrupted threads from the receiver after which the magazine is slid forward so that its rear end will entirely clear the rear face of the band 18. The sliding handle may now he slid forward on the magazine until the rear end of the action-bar 15 has been moved forward far enough to also .clear the rear face of the band 18. As the handle is slid forward as described to the limit of its forward excursion and into its take-down position so called, it carries the magazine along with it into its take-down position, so called,

since the sleeve 12 of the handle is abutting upon the spring 24: of the magazine when the handle begins to move forward from its so called normal position. Now just before the handle reaches the limit of its forward excursion, the holding-cam 2 on the gunbarrel ,3 engages with the inclined face 5 of the slot 6 in the cap 7 of the handle, whereby the handle is caused to revolve slightly on the magazine which in turn causes one of the .side faces .of the actionbar :15 to engage with one of the side walls of .the opening 18 in the band 18, whereby the action-bar is converted for the time being into a torsion spring so as to bind the cap 7 upon the wedge 2 which thus frictionally holds the handle at the limit .of its forward excursion while the handle being also the rear end of the magazine .and the rear .end of the action bar are held in their clearance positions forward of the rear face of the band 18 upon the barrel 3 which is now free to :be turned into or out of the receiver. When the gun has been taken down the barrel and magazine are handled with greater convenience on account of the fact that the magazine and handle are prevented ;by the said cam '2 from shocking back and forth. After the gun-barrel has been again screwed into the receiver, a slight rearward pull upon the handle causes it to ride off the holding-cam 2, permitting the magazine to be slid back into the receiver into which it is screwed by being turned a quarter turn by the pin '22. The handle is now slid back for the connection of the rear .end of the action-bar 15 with the actionmechanism within the receiver.

I claim 1. In a take-down firearm, the combination with the barrel thereof, of a sliding handle, an action-bar extending rearward -therefrom,'and means located upon the barrel for .coaction with the handle for holding the same at the limit of its forward excursion or in its take-down position.
