CHARLES M. STAFFORD, OF MILWAUKEE, VISCONSIN.

-HVIPLEMEINT FOR CLEANING GUN-BARRELS.

SPECIFIGATION forming part of Letters Patent No. 514,514, dated February 13, 1894.

Application filed April 25,1893. Serial No. 471,798. (No model.)

To all whom it may concern:

Beit known that I, CHARLES M. STAFFORD, a citizen of the United States, and a resident oflllilwaulreain the county ofMilwaukee, and in the State of Wisconsin, have invented certain new and useful Improvements in Implements for Cleaning Gun-Barrels, &c.; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to new and useful improvements in the construction of devices for cleaning gun barrels or analogous tubular articles, and consists inthe matters hereinafter described and pointed out in the appended claims.

In the accompanying drawings yillustrating my invention Figure 1 is a view partly in l side elevation and partly in central longit udinal section on line 1--1 of Fig. 3, of a gun barrel with my improved cleaning device applied thereto. Fig. 2 is a tcp plan view of one end of my improved device. Fig'. 3 is a cross sectional View taken on line 3--3 ot Fig. 1.. Fig. 4 is a cross sectional view of the wiper, on line 4 4. of Fig. 1. Fig. 5 is a detail view of a different form of wiper.

In said drawings, A designates the gun barrel and B a wiper secured to a suitable cord C, and arranged to be moved back and forth within the bore of the gun barrel. Suitable pulleys D D are arranged to be supported in any suitable manner adjacent to the ends of the barrel A and the cord C is passed around said pulleys and arranged to extend through the bore of the barrel A in the manner illustrated in'Fig. l of the drawings.

Any desired form of devices may be employed for supporting the pulleys in position, the particular form of said devices shown 1n the drawings comprising suitable plates E E arranged to be engaged -with the outside Yot' the barrel at opposite ends thereof and each provided with a shoulder e arranged to engage with the end ot the barrel as shown. Suitable curved arms E E are pivotally engaged with each other and with the plates E E, as at e e and are arranged to embrace the barrel A in the manner shown more particularly in Fig. 3. These arms are provided at their free ends with transversely entend'- ing arms e2 e2 preferably covered with a cornparatively sott material, such as rubber. A

suitable device is provided for causing said arms to firmly clasp the barrel A between its transverse end pieces e2 e2, as for instance, as shown in Figs. 2 and 3, more particularly, in which one oi' the said arms is prolonged beyond the pivotal connection e', and is carried downward adjacent to the free end of the other arm E', and a suitable thumb screw E2 is threaded through said end, and is arranged to engage with the free end of said other arm. By adjusting this screw so as to bear forcibly against the free end of said arm, the two arms may be adjusted in an obvious manner so as to grasp the barrel firmly between their free ends, and by loosening said screw, the arms will be allowed to spread so as to permit them to be removed from the barrel.

In the particular form of construction shown in thedrawings I have shown the pulleys D D as journaled at the free ends of arms F F, which are pivotally supported upon the plates E E, as at f j', suitable standards F F being arranged to extend upwardly from the upper side of the plates E E at the sides of the arms F F, and set screws f f arranged to secure said arms to said standards in their adjusted positions. These standards, and the adjacent faces of the pivoted arms F are conveniently roughened or corrugated as shown at f2, in Fig. l, so as to enable the said arms to be tightly clamped in position. By this construction, the arms F F may be adjusted so as to bring the pulleys D D into position to cause the cord C to travel centrally within the bore of the barrel A, in an obvious manner.

As shown in Fig. l, of 'the drawings, one end ot the cord C is detachably engaged with the wiper so4 as to enable it to be disengaged therefrom in order to allow the wiper to be drawn out of the gun barrel when desired, and to this end I provide the end of said cord with a suitable snap book G adapted for engagement with an eye o, at the end ofthe wiper B. I tind it convenient to construct the Wiper B from a spirally coiled wire, the convolutions ot which are preferably made smaller in diameter at the ends of the wiper than at the center. A rod Z2 extends centrally through the inside of the coil B, and is provided at one end with a collar b with which one end of the wire forming said coil is engaged. The other end ot' this rod b is screw IOO j usted so as to fit within gun barrels of different diameters of bores.

As a further improvement, l may provide suitable slots B and B2 in the opposite ends of the rod b, through which a strip of cloth may be passed, and twisted around the outside of the coil B.

When i-t is .desired to clean the gun barrel of an accumulation of dirt and rust which adheres strongly to the inside of the barrel, the

- spiral Wire cleaner may be used in the manner shown in the drawings, Without anycover of cloth but when it is simply desired to Wipe the inside of the barrel clean, it is preferable to apply a strip of cloth to the outside of the spiral, so that the Wire will not ,come ydirectly into `contactvvith the inside of the gun barrel.

ln using my improved cleaner, the supporting devices which carry the pulleys D D, are secured to the muzzle and breech ends of the barrel, and the cord O slipped through the barrel and the snap hook C at the endof the cord, .engaged with the .eye cin the end of the rod h, when the operator may grasp the cord upon the outside of the barrel, and by a longitudinal movement of said cord, may move the cleaner B, back and forth upon the inside of the barrel. When the gun barrel has been sufficiently cleaned, the cleaner may be readily removed therefrom by simply detaching the hook C from the eye c, and slipping the wiper from the end of the barrel.

If desired, a handle may be provided `upon the cord C as shown by the dotted lines at G, in Fig. l, said handle serving to facilitate the operation of cleaning the gun-barrel in an oblique manner.

lf desired the form of cleaner shown in Fig. 5, of the drawings, may be employed, said cleaner consisting of a bar l-l, slotted as at H and provided at opposite ends with eyes h h one for engagement with the end of the cord O, and the other for engagement with the snap hook.

I would have it understood that I do not wish to limit myself to the exact form of construction shown in the drawings, and that the construction of the supporting devices which engage With the ends of the gun barrel may be modified as may be found necessary to adapt them to various styles or makes of guns.

My improved cleaner is at once simple andl strong in construction, easily operated, effective in its operation, and readily applied to or detached from the gun barrel.

Having thus described my invention, what l claim as new, and desire to secure by Letters Patent, is

l. The herein described implement for elcaning gun barrels, comprising suitable pulleys journaled in suitable supporting devices adapted for engagement with opposite ends of the barrel, a cord arranged to run over said pulleys, and a suitable Wiper or cleaning device secured to said cord and arranged to travel longitudinally Within the gun-barrel, substantially as set forth.

2.
