AUXILIARY BARREL FOR BREECH-LOADING SPECIFICATION forming part of Letters Patent No. 745,464, dated Decemberl, 1903. Application filed February 21, 190.8. derial No. 144,436. (No model) To all whom it may concern:

Be it known that I, VERNON O. TASKER, a citizen of the United States, residin g at Wash I ington, District of Columbia, have invented i certain new and useful Improvements in Auxiliary Barrels forBreech-Loading Guns; and I do hereby declare the following to be a full,

clear, andeXact-description of the invention,

, such as will enable others skilled in the art to rewhich it appertains to make and use the same. This invention relates'to auxiliary barrels 4 for breech-loading guns, or, as they are usually termed, suboaliber devices; and it consists-in the construction hereinafter set '15, forth. 7

The present invention isespeciallydesig'ned for a-gun using fixed ammunition or-a. car- Bridge and there is'iio tapered-portion of .the

large gun on which to obtairr'a bearing for no one of the adapters. Henceit is necessary to provide some means othei t an expansion pre- at the rear of the snbcaliber device-to vvent the latter from jarring forward.

In the annexeddrawings, Figure 1 represents in section andside elevation a portion of a gun and. the device within the gun; Fig.

2, an enlarged sectional View of the breechhoop; Figs. 3 and ,4, end. and sectional views of the'adapter ring; Figs. 5 and 6,end, seco tional,and partialdetail'of the adapter-sleeve;

Fig. 7, a sectional view-0f a modification of the breech-hoop; Fig. 8, a view ofthe adapterscrew.

V In the drawingsjthelet-ter A indicates the g5, auxiliary burrelorgsnbcaliber gun,which may be built up in'-tlieiusual way, consisting of the tube a, the jacket a, and the breech-hoop B. This barrel Ais provided on its exterior surface with two sets of screw-threads:a. a

40. of the same pitch and direction, one set, a being near the muzzle a and the other set,

a being about the middle a -of the subcaliber gun. Engaging the front threads a? is a front adapter 0, whichfits on its outer rim 5- c the bore of the large or main gun.

ing the threads a isthe middle adapter D,

on its outer rim d fitting the bore of the large gun. The rear end of the tube a has the usual breech-hoop 3, upon which is placed a steel ring E "having the flange-E..- .flhis ring Engag- 1 large or main gun, thus firmly holding the ving the subcslibergun from being jarred forward when the gun is fired.

is provided with a number of holes e and at one side with a screw-seat 6. This screwseat e runs obliquely fromone'face, e of the ring outwardly'to the outer periphery of the ring and has a threaded portion e at the face e and a smooth portion i At the inner and upper end e of the smooth portion e of the seat e there is a slit or open is within the smooth portion 6 of this seat, the point 9 of'the screw passing through the slit'or opening e and pressing against the 7::

tongue f of the. sleeve F.

The subcaliber gun, with the several adapters, is put in position as shown in Fig. 1. After they are .duly placed and adjusted by turning the barrel within the adapters the screw G is turned inwardly, forcing the point g thereof through the slit or opening ,6. against the tongue f of the sleeve F and binding the tongue against the inner face or bore of the subcaliber gun in place. The flange E ofthe ring E is fitted to the face of the larger gun around the inner end of the bore, occupying the place where the rim of the cartridge-case fits, and as a mushroom gas-check is not used with a gun of this caliber the flange may be used and it prevents any forward jarring of the subcaliber gun. I

If desired, the ring E may be omitted and the breech-hoop B- be made with the flange and having the screw-seat for-the adapterscrew G. a .1;

- Having thusdescribed my invention, what I'claim is- 1. Meansof securing a subcaliber gun in place provided with a. variable adjustment for holding thesubc'aliber gun tightly within the larger gun, and additional means .for prevent- 2. Means of securing a subcaliber gun in l place provided with a variable adjustment for holding the subcaliber gun tightly in place within the larger gun, and a flange fitting the face of the larger gun to prevent the subcaliber gun from being jarred forward when the gun is fired. V

3. Means of securing a.- subeal'iber gun in place and preventing its being jarred forward when the gun is fired provided with a. slitted ring having a tongue onthe outside, a screw for bearing against such tongue, and a. flange on the outer end.

4. The combination of the ring, E, having the slit or opening, e, and the flange, E, adapted to-the face of a large gun; the screw, G, held in the ring, E, and passing through the slit or opening, a; and the sleeve, F, hav- =in the ton ue, 7 cornin over the slit or b b u 3 (1 opening, 6, of the ring, E.

In testimony-whereof I aiffix my signature in presence of two witnesses.
