TAKE-DOWN FIREARM.

Specification of Letters Patent.

Patented Sept. 10, 1907.

Application filed May 3,1906. Serial No. 314,934.

To all whom it may concern:

Be it known that I, FRANK C. CHADWICK, of Utica, in the'co'unty of Oneida and State of New York, have invented certain new and useful Improvements in Take-Down Firearms; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art t0 which it appertains to make and use the same, refer ence being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

The object of my invention is to provide a takedoWn construction for fire arms which is simple and effective in its construction, easily and conveniently operated and not liable to get out of working order.

In the drawings Figure l shows a side elevation of a hre arm wherein the take-down construction of my invention is embodied. Fig. 2 shows on an enlarged scale from Fig. l a partial side elevation of the barrel removed from the receiver or frame and having the fore arm replaced in position on the barrel and shown mostly in section. Fig. 3 is a longitudinal section of the fore arm removed from the barrel, showing particularly the catch by means of which it is secured to the barrel and other details. Fig, 4 shows in perspective section a portion of the barrel and a portion of the fore stock showing details hereinafter referred to. Fig. 5 shows on an enlarged scale partially in section the frame and parts of the barrel and fore stock illustrating details of the construction. Fig. 6 shows the frame with the barrel removed and a portion of the frame shown in section. Fig. 7 shows a side elevation of the rear end of the barrel removed from the frame. Fig. S shows a bottom view of the same. Fig. 9 shows a rear end view of the barrel and the fore stock when it is detached from the frame and reassembled. Fig. l0 shows a similar view of a modified form of construction.

Referring to the reference letters and figures in a more particular description7 l indicates the frame of the gun, 2 the barrel, and 3 the fore stock which are the main parts with which we have to deal. The frame l is provided with a barrel socket 4 having interrupted screw threads 5 therein. The socket 4 is adapted to receive the rear end of the barrel 2 which is sized to be received therein and is provided with an interrupted screw thread 6 adapted to engage and cooperate with the screw threads of the barrel socket. The lower portion of the frame l in the form of construction illustrated, includes a magazine chamber, the forward open end of which forms a socket 7 of circular form which receives the projection 8 on the rear end of the fore stock 3. This projection 8 is preferably formed on a collar piece 9 employed or provided on the rear end of the fore stock which fore stock is preferably of wood except as to the collar 9 and other details hereinafter mentioned. The collar 9 is provided with wing-like portions 9l1 adapted to extend up on either side of the rear end of the barrel and fore end of the frame, and is also provided with a bit l0 adapted to engage in a recess 2l in the under side of the barrel, and may also engage, as shown in Figs. 5 and 6, in a recess 4a in the forward end of the wall of the socket 4, This latter feature of engaging in a recess in the wall of the forward end of the socket 4 maybe omitted, however, in which case the bit l0 would only be made of sufficient length to engage in the recess 2 in the under side of the barrel forward of the end of the socket 4.

At a suitable point forward of the frame on the under side the barrel 2 is provided with a rigid stud or projection ll, which is provided with an inclined catch shoulder adapted to be engaged by a catch bolt l2 provided in a small casing 13 secured in a suitable recess in the forward portion of the fore arm 3. The bolt 12 is impelled towards a locked position by a spring 14 and adapted to be moved to unlocked position by a thumb piece l5 connecting with the bolt. The forward portion of the catch frame I3 is provided with an inclined face as indicated at 13, which serves to draw or move the fore stock toward the rear as the same is moved toward the barrel, and the recess in the fore stock which receives the catch stud or projection ll is also arranged to fit quite closely the forward side of the stud projection in order to prevent relative longitudinal movement of the fore stock and barrel when detached from the frame and reassembled. It will be noted that the inclined shoulder on the bolt l2, cooperating with the inclined shoulder on the catch stud ll, serve to draw the fore stock against the barrel and take up any looseness which might otherwise exist. The fore stock is grooved longitudinally to fit the under side of the barrel and in the bottom of this groove to the rear of the catch before described there is provided a socket 1G also adapted to receive and quite closely surround the stud or catch projection ll before mentioned,

In order to take down the gun from the assembled position shown in Fig. l the breech bolt 17 is first withdrawn more or less, more particularly to disengage the forward end of the extractor 18 from the recess 19 in the rear end of the barrel provided to receive it. The operator then withdraws the catch bolt 12 by forcing it to the rear by means of the thumb piece l5 and forces the forward end of the fore stock away from the barrel. When freed from the stud or catch projection l1 the fore stock is then moved forward disengaging the rear projecting portion 8 thereof from the socket in the is employed. When entirelyvv 'freed the foreA stock isv moved forward on the barrel and the stud or projection ll is engaged in the socket 16. The lore arm then serves as a wrench by means of which the operator c an. give the barrel ahalfdrevolution with reference vtov the" frame to disengage the .interrupted screw Ythreads 5' and (l. When these are disengaged the barrel can'be withdrawnlongitudinally out othesocket 4; whereby the gun becomes completely taken-down. For conveniencef in handling thc fore stock 3 will preterably'be reappliedto the barrel, being secured in position by the catch bolt l2. When so reapplied .the parts will appear as shown inFig. 2 ofv the draw-ings. To assemble the parts or set up the gun alter removing the ore stock from the barrel in obvious manner, the operations belore described are performed in the reverse order. In Fig. lO. there is shown a modiiied form of construction wherein an interrupted thread of three sections, namely, a, b and c, is employed in lieu of the two section. thread ot'the previously described construction. y

What l claim as new and'dcsire to secure by Letters Patent is: f

1. In a take down mechanism for a iire arm the combination of av frame having a barrel socket with interrupted screw threads, a barrel having interrupted screw threads adapted to enter said socket, a removable fore arm having means for dctachably securing the same to thc barrel and having a portion adapted to engage the frame when assembled and a bit y10 adapted to engag a suitable recess in the undersideof the barrel at a point cbntiguous to the socket and protected by the fore stock and lock it from rotation, substantially as set forth. p y A 2. In a take down mechanism for iire arms the combination of a frame having a barrel socket with interrupted screwA threads, a barrel having interrupted screw threads `adaptedto-enter said socket, a removable fore arm having means for .detachably securing the same to the barrel and vhaving' a bit 10 adapted to engage in suitable alining recesses'4i'nllie 'socket and barrel respectivly`aiid`lo`ck the VVlun-rel from rotation, substantially as set forth.

3'. In a take down mechanism for rire arms the combination of a frame having a barrel socket with interrupted screw threads and the fore arm/socket under Athe barrel socket, a barrel havinginterrupted screw. threads adapted to enter said barrel socket, a removable fore arm having means for detachably securing the same to the barrel and having a portion received in said fore arm socket and 'a' bit projecting from the side fitting the barrel engaging a suitable recess in the barrel and adapted .torlock the barrel from rotation with reference to the frame, substantially as set forth. l

4. In a fire arm the combination ot a'frame' having a barrel socket with interrupted screw threads, a barrel' adapted to be received in said socket and having interrupted screw threads and having a lstud or projection, a tore-arm grooved to fit the barrel and having' a socket to receive said barrel stud or projection 'whereby when the fore-arm is placed and` saidY socket Yengaged with said stud or projection it is adapted to serve as'a wrench for the barrel, substantially as set forth. v y

In witness whereof, I have aixed my signature, in presence of two witnesses.
