AUXiLiARY RIFLE-BARREL AND EXTRACTOR THEREFOR.

SPECIFICATION forming part of Letters Fatent No. 282,194, dated July 31, 1883.

(X0 model.)

To a whom it may concern Be it known that I, PETER R. HowE, acitizen of the United States, residing at Fortsville, in the county of Saratoga and State of New York, have invented a new and useful Improvement on the Shelton Auxiliary Rifle- Barrel and an Extractor Thereto and Th erefor, otwhich the following is a specification.

My invention relates to improvements in Sheltons auxiliary rifle-barrel to be used in breech loading shotguns, and an extractor thereto and therefor, which extractor acts as a perfect lock to the barrel, preventing it from moving in a revolving manner, and operates as a perfect extractor of the empty shell or cartridge by the ordinary method of opening breech-loading guns. The rifle-barrel is made the full length of the shot-barrel, in which it is inserted, with a small flange-nut which screws on the end of the rifle-barrel after the same is inserted in the shot-barrel, the flange coming in contact with the muzzle of the shot-barrel, thus preventing the rifle-barrel from moving horizontally or being drawn by the extractor.

The Shelton auxiliary rifle-barrel is made as follows: The barrel is made six to ten. inches shorter than the shot-barrel in which it is inserted, with a foul protector or tube attached thereto, making barrel and foul-protector the exact length of shot-barrel. There is a centering-collar placed around the muzzle of the riiie-barrel for the purpose of centering the riflebarrel inside the shot-barrel. The breech of the barrel is made with a flange which extends around the barrel and rests on the groove or shoulder in the ordinary breech-loading shotgun-extractor, the purpose of which is to draw the barrel when opening the gun, so that itmay be readily removed from the shot-barrel. The effect, however, of this continual drawing and replacing the rifle-barrel every timethe gun is opened and shut is to wear upon the centeringcollar, thus loosening the rifie-barrel inside the shot-barrel and throwing it from its central position therein and producing a revolving motion of the barrel on firing, there being no locl; to prevent either the horizontal or revolving motion. The extractor used to eject the empty shells from this barrel is either an automatic or hand extractor.

My improvement is as follows:

In the drawings, Figure 1 is a longitudinal section of my improved riiicbarrel in position in a shotgun-barrel. Fig. a. side elevation of rifle-barre] and attachments. Fig. 3 is a rear view of shot-barrels with rifle in place; Fig. 4, a side view of the extractors detached.

The letter a designates the barrel of a shot gun of usual construction; I), my improved rifle-barrel, having an enlargement, (1, near the muzzle, whichjust fits the bore of the shotbarrel, and a screw-threaded portion, 0, forward of this enlargement. The barrel 1) extends nearly or quite to the muzzle of the shot-barrel, and is secured at themuzzle by nut c, which screws on the thread 0 of the barrel, and has a collarat the front end of greater diameter than the bore of the shot-barrel.

At the rear of the rifle-barrel there is a flange, f, cut away in part to permit the operation of the extractor of the shotgun. The barrel also has a slot, 1', for the passage of the extractor of the rifle-barrel.

The extractor got the shot-barrelsis of usual construction, except that it has a dovetail groove across its face, as shownin Fig. i. In this groove the bar 7b is held to form an extractor for the rifle-barrel. The bar 71. can be turned so as to project at either side of the main extractor, so that an auxiliary barrel may beilr serted into either one of the shotgun-barrels when properly constructed for the purpose.

The projection d on the rifle-barrel serves to center 'sai d barrel in the gun, and it is secured from endwise movement by means of nut c an d flangef. The cut-away portion of fiangef, as well as the groove 17, serves to hold the riflebarrel from rotation by engagement with the extractors, as shown and explained.

The only alteration necessary to apply my device to shotguns in common use is the cutting of the slot in the extractor, which does not change its usual mode of operation.

The whole device consists of but three parts vi z. the barrel, the retaining-nut, and the ex- 9 tractor. It is therefore simple and not liable flange at its rear end, a flange which fits the bore of the shotgun, near its muzzle, both flanges being integral with the rifle-barrel, and a nut extending in front of the shot-barrel and engaging a screw-thread on the rifle-barrel, all substantially as stated.

2. The extractor of a double-barreled' shotgun, having a dovetailed slot across its face,

in combination with the extractor of an insertible rifle-barrel, constructed substantially as described, so that said extractor may be re versible and capable of operation on either side of said shot-cartridge extractor, as set forth.

PETER R. HOWVE.
