GUN-WIPER.

SPECIFICATION forming part of Letters Application filed October 20,1886. Serial No. 216,708. (No model.)

To all whom it may concern:

Be it known that I, J AMES D. SMITH, a citizen of the United States, residing at Springfield, county of Hampden, and State of Massachusetts, have invented a new and useful Improvement in Gun-Wipers, of which the following is a specification.

My invention relates to an improved mopholder and ferrule for the rod of a gun-wiper; and it consists in the combination and construction, as hereinafter described, and. more particularly pointed out in the claim.

My invention is fully illustrated in the accompanying drawings, in which- Figur'es I, II, and III are partial longitudinal sections of my device in ditlerent stages of construction. Fig. IVis a perspective view of the complete device, and Fig. V shows the device combined with a rod and mop.

A tube, B, adapted in size to enter the gunbarrel, .has a link, D, of the diameter of the bore of said tube, passed into one end of the tube until ithas a. goodbearing upon the inner sides of said tnbe'B, as seen in Fig. I. Apin, to extend from-side to side of it and within the link D, as seen in Figs. I, II, and III. The link is pulled up to bear against the pin. A plug, 0, filling the tube B, is inserted therein to a point a. little distance below the link end within the tube, as seen in Fig. III, and molten metal is run into the tube above the end of plug 0 to fill said space flush to the top of the tube.

. The link D, I form of drawn metal, such as stout wire having its grain parallel with its length. Any soft metal may be used for the filling H. (Shown in Fig. III.)

The plug 0, when withdrawn, leaves a ferrule, which may be provided witha screwthread to better enable it to be combined with a rod, I; or the ferrule may be pinned to the rod, as shown in Fig. V, or only fitted to the rod to be held by friction, its large inner diameter enabling it to be combined imany of these three ways firmly with the rod. The

metal filling H, uniting with the tube B and Patent No. asst-inflated January 4,1887.

' embedding the pin b and recessed end of link D, makes the link, in effect, integral with tube B, and the pin 1) efi'ectually prevents the link from pulling out, and under a torsion strain from rotating with the filling in the end of the tube.

The end of rod I within the ferrule, by coming against the filling H, prevents the link from being driven within the tube; but the the staple made by the projecting part of link D relieves the link of all strain in pushing the wiper through a barrel, and cannot wedge the waste or rag used as a wiping material within the barrel so as to jam it fast, as frequently ocours in a wiper having wedge-shaped sides to the bottom of the slot therein, as the wide shoulder in this wiper at right angles to the axis of the barrel enables my mop to be pushed ing substance than the wipers in general use. Now, having described my invention, what I claim is-- consisting of a tube, B, drawn-metal link D, pin b, and metal filling H, run in when molten to combine with the tube, link, and pin, ar ranged as shown, and to leave a staple with a solid shoulder for its base, and a ferrule in the tube adapted to be combined with a rod or handle, substantially as shown and described.
