GUN CLEANER.

Application filed April 13, 1926. Serial No. 101,743.

This invention relates to a new and improved article of manufacture which may be conveniently referred to as a gun cleaner, the same having more particular reference to an especially constructed plunger rod which is adapted to be inserted in and reciprocated through the barrelof a gun, pistol, or other similar firearm for the purpose of loosening and removing powder deposits, burnt particles, and the like, to promote accurate shooting.

Briefly, the invention comprises a rod having an appropriate hand grip, a cylindrical shank extending from the hand grip, an especially shaped head or knob on the end of the shank, and a lubricated patch which is placed over the head and around the shank for literally scrubbing the interior of the barrel.

its far as I have been able to ascertain from prolonged investigation and study, the ordinary barrel cleaning rod is constructed from metal, being sometimes provided with a metallic bristle brush to facilitate in scraping the bore. Obviously, metal cleaners of this kind are injurious in that they forcibly rub the metal of the barrel and eventually distort it in one way or another. This results in an inaccurate flight of the project-ile.

It follows that one of the outstanding features of this invention is to make the entire plunger of hard wood sufliciently rigid to permit it to be properly reciprocated in the cleaning operation, but not hard enough to any way injure the wall of the bore.

An equally important advantage is derived from the use of a small lubricated cloth patch which is used in association with the plunger for softening the powder'deposit and wiping the same from the wall of the bore, and ejecting the same in lump formation.

Other structural features and advantages will become apparent from the following description and drawing.

In the accompanying drawing forming a part of this application and in which like numerals are employedv to designate like parts throughout the same:

Figure 1 is a side elevation of a barrel cleaning device constructed in accordance \vith this invention showing its association with the barrel of a tire arm.

Figure 2 is an enlarged fragmentary view showing more plainly the structural advandct chambers, the ordinarv is a perspective view of one of of a pistol. U

Consider-in now the barrel cleaning de vice, it will he seen that this comprises a body of wood which is turned toprovide an" appropriately shaped hand grip 2, from which acylindrical shank 3 extends. It will be noted that the shank is of a diameter considerably less than that of the hand grip, and a shoulder 4 is thus provided. The

outer end portion of the shank is gradually decreased in diameter as at 5 to take the approximate curvature shown plainly in Figure 2. The shank terminates however in an enlarged head 6, and it will be noticed that an abutment shoulder is provided at the juncture of the head and especially curved portion of. the shank. Particular emphasis is to be laid on the shape of this head 6. The outer end is, of course, flat, while the peripheral portion is rounded somewhat in the longitudinal direction, thus making it of convex form. To bring out the feature of construction of this convex head, it is to be stated that the line A is drawn through tliebrown portion, thus dividing the head into half-sections B and C, the features of which will be hereinafter made clear.

Used in connection with the device, as before stated, is a substantially square patch 7 which is preferably of an absorbent cloth such as flannel. This patch is of a size governed somewhat by the length of the curvature 5 so that the edge portions thereof will terminate within the curve of this portion 5. In other words, the edge portions of the patch must not extend onto the enlarged portion of the shank due to the wedging action which would result. I might call attention at this time to the fact that the length of the shank from the shoulder 4:

to the extremity o't'the head 6' is slightly greater than the length of the barrel 1 with which it is used. lt'followstha't a special cleaner is made for each particular caliber, and length of barrel.

In using the device, it is to be assumed that the patch 7 has been previously lubricated with a kind of material used for loosening powder deposits and incrustations. Now, the flat end of the head 6 is placed against the approximate of one side of the patch and the edge portion of the patch is doubled and to led back over the had, next, the patch covered head is forced into the muzzle end of the barrel, and the plunger forced through the barrel y grasping the hand grip in an obvious manner.

in forcing; theplunrger through the barrel. the riding on the interior ,willcause slight rotary or turning movement of the device. The edge portions of the patch will thus be wrapped about the curved reduced portion 5 of the shank. @wing to the thrust of the device, the patch will be drawn teutly about the head and owing to the compressible nature of the patch and also the properly proportioned diameter of the head, asnug fit; assured, but no binding will result. In Figure 2, l have shown the plunger in the act ot being forced through the barrel and indicating; how the cloti patch is conipressed. In Figure l the pl" gr is shown forced all. the way through the barrel with the shoulder lengaged with the muzzle end and cloth covered knob or head 6 projecting fraction at an inch beyond the breech.

will be noted that the projecting port ot the head is equal to the aforesaid sect on (1 (see Figure 2 and owing to the curvature of the head it will be seen that a clean- REC/35172160 exists between the patch the wall ofthe bore and during the reciprocatory action oi": the plunger, this clearance space has become packed or filled with the reroeae removed particles. Now", on the withdrawal of the plunger, the other half B provides a clearancespacebetween the cloth and the wall of the barrel in which any surplus materiel is collected, and withdrawn through the muzzle as the plunger is aulled out. These clearance spaces are of great importance as they prevent januuing and it inustl e remembered that in adevice of this kind, the proportions must be accurate with respect to the'particular caliber oi" the 9". barrel. It will be noted also that ow. to the curved portion 5, the wrapped en of the cloth will be'such as not to interfere with the free rec-iprocatory motion. and th device may be moved back and forth withou loosing the'patch. If the shank were of th :une diameter throughout, the wrapped portions of the cloth would be such to he and the patch WOUld'lJQCOHlG unduly ruinpleo,

and probably lost in the barrel.

llo doubt, the device will be clear from the description taken in connection with the drawings, and in View of this a more length description is thought unnecessary.

Minor changes coining within the lieh of invention cla med may be resorted to i desired;

Having-thus described the invention. i I claim as new and desire to secure by Letters Patent is As a new article of manufactur a a barrel cleaner comprising a hand grip, a cylindrical shank CIIfiGIlCllIlQfYOK] said hand grip, said shank being out a dizuneter less than that of the hand grip to provi-fle shoulder between the hand FQIlP'fill-il shan'zz. the outer end portion of the shank bc' gradually reduced in diameter to provide a neck, the free end of the shank heir-.gconstructed to provide a head, the outer end of the head being fiat and the peripheral portion being of convex torniation.

In testimony whereof I aiiix my signature.
