STRAP SUPPORT FOR GUNS.

APILlCATION FILED SEPT.12, 1912,

1,115,787, Patented Nov. 3, 1914.

T all whom it may concern:

Be. itknown that I. OTTO Paoonzvow, a citizen of the United States, residing at Vlest Allis, county of Milwaukee. and State of Wisconsin, have invented new and useful Improvements in Strap-Supports for Guns, of which the following is a specification.

Myinvention relates to improvements in strap fsupports for guns, with especial reference to that class of strap supports shown and described in my former application for Letters Patent of the United States, Serial I tiled March 11th, 1912, and allowed July 22, 1912.

The object of my present invention is to proyide means for locking the windinc spool with the strap extended to any esired length. I

Incidentally to the above object, I also provide means whereby the spool may be manually actuated and the spring illustrated in my former patent dispensed with.

Inthe,drawingsFigure 1 is a side view of a gun embodying my invention. Fig. 2 is a sectional view of the Winding spool and casing, removed from the gun stock, and

showing also a portion of the strap partially wound thereon. 3 is a side view. partly in section, of a winding spool and casing embodying a modified form of my invention, in which a. winding spring is employed. Fig. 4 is a sectional view otthe same, drawn t a. plane exposing the winding shaft.

Like parts are identified by the same reference characters throughout the several views.

The gun stock 1 has a cylindrical casing 2 socketed therein similar to that shown and-- described in my former application? A-wind ing shaft 3 extends through the casing trans versely and carries a spool 4 upon which the gun supporting strap 5 is adapted to be wound. said strap extending through a pcripheral opening 0 in the casing, substan tially as shownand described in my former application. in the construction illustrated in Figs. 1 and 2. the projecting end (3 of the shaft is flattened and adapted to receive the head 7 of a crank arm 8. The crank arm 8 is formed in sections connected with each other by a hinged joint at 10, and the outer section of the arm is provided with a locking pin 11. preferably rigidly secured to the arm and adapted to engage in holes 12- formed in the casing-flange 13. When the pin 11 is r snares STRAP-SUPPORT reasons.

Specification of Letters Patent.

Patented Nov. 3, o

Application filed September 12, 1912. Serial No. 719,905.

inserted in one of these holes 12, the crank arm 8 is. locked against, rotation and is also held closelytothe adjacent wall of the casing 2. pin 11 is adapted to fit snugly in theholes 1:2 and to bind therein by frictional contact. The hinge-l0 is alsofpreferably formed with a tight-fitting pintle,

whereby an accidental swinging of onesection upon the other-is prevented. By manually pulling upon the pin 11, however, said pin may be withdrawn from the hole 12 in which it is engaged, and the outersection simultaneously swung to a position at right angles to the inner section, whereupon said outer section may serve as a crank handle to facilitate rei olving the shaft. 6 and winding spool 4 When the strap is extended or rewound uponthe spoolto the desired extent, the outer section of the crank arm 8 will be swung into alinemcnt with the inner section, as illustrated in Fig- 2. and the pin 11 reengaged in one of the holes 12. The outer end of the strap being provided with a fastening 15 engaging an eye-piece 16011 the gun barrel, it is obviousthat when the strap the shoulder from irritating pressure, such as'would be exerted by the gun barrel if the strappere not used. It is ob ious that the strap may be errtrndedflto desired ektent from the adjustment illustrated by full lines in Fig. 1 to facilitate carrying the gun by suspending it from the shoulder, or from a wall support, or any other desired point.

By employing a jointed crank arm 8, l am enabled to use a thin and comparatively wide arm, which will lie substantially flat against. the exposed wall of the casing, the pin 11 being provided with a broad fiat head, which projects but little from said wall. The arm, therefore. will not catch in the clothing of the user, or otl'ierwise interfere with the ordinary use of the gun. This arrangement, however, makes it highly desirable that the arm 8 should be jointed in order that the outer section may be swung ioo outwardly to facilitate rotating the crank and also to Withdraw thepin 11 from the casing holes 12. f

Referring to Figs. 3 and *4, it will beobserved that a strap Winding spool 18 is em-p ployeihand this spool is provided at one end .withpan end disk 19, provided with a series of notches 20. A shaft 21 is employed simi-, lar to the shaft 3, and a casing 22 inclo'ses the spool and is provided with ya sepa. ratecompartment 24-, snnllar to that shown: in my former application, and in which a ivindin s rin 25 'is located, the ends n P g of said spring being connected, 'with the shaft and easing respectively. A segmen-' tal locking member 26 is pivoted at 27 to the front Wall of the casin and is provided tract locking a'r1n26 and withdraw lip 28 adjustment "is reached,

Wardly against the tension of the from the notch 20 in which itis engaged. As soon as the lockmgarn s retracted, the

s rin 25 will be eflective'to vvind u the strap, but if itis desired to extend the strap,

this can be done :by pulling the same outwinding position of strap projection" 31 may be released, whereupon lip 28 willautoi'uat ical'ly ,reengage with oneof the notches 20 and lock the spool against rotation.

'Itwill be understood that'if desired, the crank arm 8 shown in Figs. 1 and 2 may be applied to the shaft used for unwinding spring. I When the desired the spring or'for looking the spool. \Vherethis is done, the lock-, ingi arm 26 may be dispensed with; in this i I I 210 f Figs. 3 and 4, and

eonstruction aswell as in the construction shown in Figs. 1 and 2. Where the gun stock is thick enough so that a socket may be provided therein of suflicient depth to readily receive the casing 22, the construction .SllOWll in Figs. 8 and -1- Will preferably be employed, for the reason that thesurtaoe of the casing will have no projecting parts eX- cept the slight projection of the member 31, but where the gun stock is thin and a deep easing cannotbe readily employedfthe'jonsti-uetion shown in Figs. 1 and 2 willbe preferred. The additional easing depth re.-

quired for the reception of the spring 25 is not required for the constructionshoivn in Figs, 1 and'2.'
