F. F. BURTON.

TAKE-DOWN FIREARM.

APPLICATION FILED JULY 3. IBM.

Patented Aug. 22, 1916.

FRANK F. BURTON, OF EAST HAVEN, CONNECTICUT, ASSIGNOR TO WINCHESTER REPEATING ARMS CO., OF NEW HAVEN, CONNECTICUT, A CORPORATION.

TAKE-D OWN FIREARM.

Application filed July 3, 1916.

T 0 all whom it may concern:

Be it known that I, FRANK F. BURTON, a citizen of the United States, residing at East Haven, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Take-Down 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-

Figure 1 a broken view in right hand side elevation of a gun constructed in accordance with my invention. Fig. 2 a broken view thereof partly in side elevation and partly in vertical, central longitudinal section. Fig. 3 a detached view in rear elevation of the gun-barrel and forearm, showing my improved take-up screw in place in the latter. Fig. 4 a detached view in front elevation of the receiver-extension. Fig. 5 a detached view in side elevation of the takeup bushing. Fig. 6 a corresponding view of the take-up screw. Fig. 7 a view in elevation of the slotted forward end of the takeup screw.

My invention relates to an improvement in take-down firearms, the object being to provide simple, convenient and effective means for taking up the play or shake which may result from the wearing of the means by which the gun-barrel is removably secured to the receiver of the arm.

lVith these ends in View, my invention consists in a take-down firearm provided with a take-up having certain details of construction as will be hereinafter described and pointed out in the claims.

In carrying out my invention as herein shown, I employ a cylindrical take-up screw 2 enteriorly threaded throughout its length and formed at its rear or head end with a flat bearing-face 3 having a kerf 4. The forward end of the said screw is formed, as shown, with a deep concentric chamber 5 and with a'longitudinal slot 6, though this is not essential. The sald screw is mounted in a long internally threaded bushing 7 located in a circular chamber 8 formed in the rear end of the wooden forearm 9, the rear end of the bushing having a knurled band 10 embedded in the wood to prevent the bushing Specification of Letters Patent.

Patented Aug. 22, 1916.

Serial No. 107,259.

from turning in the chamber 8. Preparatory to mserting the take-up screw 2 into the bushing 7, the forward end of the screw, if slotted as shown, is very slightly spread apart so that when screwed into place it will be compressed and so held under tension against rotation. The flat bearingface 3 of the screw impinges against the fiat forward face 11 of a receiver-extension 12 formed with a threaded opening 13 adapting it to be screwed over the reduced forward end let of the receiver 15 which may be of any desired construction, and which, as shown, has an internally threaded opening 16 for the reception of the threaded shank 17 of the removable gun-barrel 18 which is secured in place against rotation by means of a locking-screw 19 passed upward into the shoulder 20 of the barrel through an opening 21 leading upward from the lower face of the receiver-extension 12.

The forearm 9 is rigidly secured to the barrel by means of a screw 22 passing upward through it into a lug 23 extending into a recess 24: formed in the upper face of the rear portion of the forearm, the said screw 22 having its upper end reduced as at 25 to enter a hole 26 in the cylindrical portion 27 of the barrel. The said portion 27 of the barrel is provided for the application of the forearm-lock which comprises the lug 23 aforesaid and a band 28 with which the said lug is formed integral and from which it depends. The said band 28 is clamped upon the portion 27 of the barrel by means of a transverse clamping screw 29 passing through the split rear end of the lug 23. The upper face of the band 2S'is formed with a transversely arranged undercut groove 30 for the reception of a dovetail upon the lower face of the sight base of the rear sight of the arm. As herein shown, the forward end of the tang 31 of the magazine is secured to the receiver-extension 12 by means of a screw 32 passing upward through the tang into a lug 33 projecting rearward from the rear face of the receiver-extension 12. The butt-stock 34 extends forward to the rear face of the receiver-extension.

It will be observed that the forward end of the bushing 7 engages directly with the rear end of the depending lug 23 which is clamped solidly upon the barrel by the screw 29. Under this construction the bushing is held against forward thrusts imparted to it through the take-up screw 2.

In using the term receiver in the claims, I intend to cover, broadly, the receiver whether formed with a removable receiver extension, or otherwise.

I claim 2- 1. A take-down firearm characterized by having the rear end of its forearm provided with a take-up screw mounted in a bushing located in the rear end of the forearm and adapted to engage with the forward end of the receiver for taking up wear in the connection between the same and the removable gun-barrel.

2. A take-down firearm characterized by having the rear end of its forearm provided with a take-up screw mounted in a bushing located in the rear end of the forearm and slotted to adapt it to be spread open so as to be frictionally held in place.

3. A take-down firearm characterized by having the rear end of its forearm provider with a take-up screw for co-action with the forward portion of the receiver of the arm, the said screw being cylindrical and having its forward portion chambered and longitudinally slotted to adapt it to be spread open so as to be frictionally held in place at. In a take-down firearm, the combination with the receiver thereof, of a gun-barrel removably secured thereto, a forearm, a bushing located in the rear end of the said forearm, and a cylindrical take-up screw mounted in the said bushing in position to have its rear face engaged with the front face of the said receiver, and slotted throughout a portion of its length to adapt it to be spread open so as to be frietionally held against rotation in the said bushing.

5. In a take-down firearm, the combination with the receiver thereof, of a gun-barrel removably secured thereto, a forearm, a forearm-lock applied to the said gun-barrel and formed with a depending lug entering the upper face of the said forearm, a bushing located in the forearm and having its forward end engaged with the said depending lug, and a cylindrical take up screw mounted in the said bushing for engaging with the receiver to take up the wear inthe connection between the gun-barrel and the receiver.
