PENNSYLVANIA, ASSIGNOR OF ONE- HALF TO ALVIN C. SPINDLER, OF EDGEWOOD, PENNSYLVANIA.

SPECIFICATION forming part of Letters Patent No. 614,191, dated November 15, 1898.

Application filed March 2, 1898.

To all whom it may concern:

Be it known that I, ISAAC M. WEILLS, a resident of Washington, in the county of Vashington and State of Pennsylvania, have invented a new and useful Improvement in Devices for Cleaning Tubular Articles; and I do hereby declare the following to be a full, clear, and eXact description thereof.

My invention relates to a tool for cleansing or polishing the interior of tubular articles.

The object of my invention is to provide a tool of such form that the cloth or cleaning material employed therewith will so gather and wrap itself around said tool when forced into the tube to be cleaned as to form a close compact cylindrical wad which will fit tightly within the bore of the tube, so that when moved up and down therein the said Wad will rub all points on the interior and remove all foreign matter therefrom.

To these ends my invention comprises, generally stated, a tool for cleaning or polishing the interior of tubular articles having aspindle with a series of concentric rings formed thereon with beveled peripheries, each of said rings being of smaller diameter than the preceding one, and with spaces formed between the rings, the largest circumference of said rings being at their upper or inner edges, so that when the cleaning-cloth is forced linto the tube by said tool said cloth will adjust itself in and around said rings in such a way as to form a Vcompact cylindrical cleaningwad.

To enable others skilled in the art to make and use my invention, I will describe the same more fully, referring to the accompanying drawings, in which- Figure lis a perspective view of my improved tool. Fig. 2 is la view of same in a tube in the act of cleaning, the tube being in longitudinal central sect-ion for purposes of illustration. Fig. 3 is an end view of the tool. l

Like letters indicate like parts in each of the figures.

As my invention can be used to great advantage in the cleaning of gun-barrels I will describe it with special reference to that particular class of tubular articles, although it Serial No. 672,292. (No model.)

is to be understood that I do not limit myself to this particular use.

In the drawings the letter c designates a spindle formed of brass or other suitable material, with a series of rings b b b2 b3 formed thereon concentric with each other. The ring b at the upper or outer end of the spindle is larger than the succeeding one b', and b than ythe one b2, and so on throughout the series. Any number of said rings may be employed, according to circumstances. The peripheries of the rings b 19'192 b3 are beveled, as at c, for the purpose more fully hereinafter set forth, the largest circumference of each ring being at its upper orinner edge. Where the tool is to be employed for cleaning gun-barrels, it may be threaded at its inner end, as at d, so as to be screwed int-o a threaded seat in the end of the rod e, or, if desired, it may be formed integral therewith. For convenience in screwing up the tool the inner ring b8 may be milled on its periphery, as at b4, so that the operator can obtain a tight hold and screw it up tight.

When in use, the tool is screwed into the rod e, and the cleaning-cloth f, of one thickness, if sufficient, or of several ply, if need be, is forced down into the gun-barrel h. As the outer ring b carries the cloth down into the barrel the surplus cloth, which collects in folds as it passes into the barrel, will wrap and entwine itself around the succeeding smaller rings b b2 b3 of the series. The spaces between the rings, as well as the graduallydiminishing diameters of said rings, permit this excess of cloth to wrap itself around the spindle in such a way as to form a dense compact cylindrical wad. Enough cloth is employed to cause the tool to enter the barrel with some resistance, so that the cloth will rub and scrape the walls of the barrel with suflicient force to remove all foreign matter. To aid in this is the purpose of the beveled peripheries on the rings. Oil or other lubricant may be employed to saturate the cloth. By working the rod up and down the interior of the barrel is thoroughly cleaned and polished, as the cloth adjusts itself to form a cylindrical wad which will rub the entire inner circumference of the barrel and no portion ICO escapes. The cloth so entwines itself about greatest circumference of each ring being at the spindle that it will not become disengaged its upper or inner edge, and each of said therefrom during the rubbing operation, so rings being of smaller diameter than the prethat there is no danger of leaving the cloth ceding one and with spaces between the rings.
