Rogovin, Milwaukee, Wis., assignor to Myron E. Schwartz, Inc., Milwaukee, Wis., a corporation of Wisconsin Application June 1, 1954, Serial No. 433,414

2 Claims. (Cl. 15-10416) This invention relates to a gun cleaner rod and particularly has reference to the construction of the rod for gripping the cloth that is forced through a gun barrel to clean the barrel.

In general, the invention is directed to an elongated jointed rod having a handle at one end and gripping means at the other end to grip and securely hold a gun cleaning cloth. The gripper means is formed of two complementary members of conical shape to provide enlarged gripping surfaces for engagement with the cleaning cloth. One of the members is recessed and the other member carries a plurality of grooves facing the recessed gripper member. The recess and grooves cooperate to provide relatively sharp gripping surfaces to grip the cleaning cloth in a manner to securely hold the cloth against slippage when the cloth is rotated within a gun barrel by the cleaning rod.

Other objects and advantages of the invention will appear hereinafter in connection with the following description of the drawing illustrating an embodiment of the invention.

In the drawing:

Figure 1 is an elevational view of the gun rod of the invention showing a cleaning cloth in section as gripped by the rod;

Fig. 2 is a longitudinal enlarged sectional view of the gripper parts gripping a cleaning cloth;

Fig. 3 is an end elevational view of the grooved gripper means;

Fig. 4 is an exploded view of the various parts of the gun cleaner rod; and

Fig. 5 is an elevational view of the cleaning cloth.

Referring to the drawing there is illustrated an elongated jointed gun cleaner rod 1 having a handle 2 at one end for manipulating the rod. At the other end of the rod is the gripping means of the invention for securely holding a cleaning cloth 3 that is employed to clean a gun barrel.

The gripping means is of two parts. One part comprises a stud 5 which is threaded at the inner end 6 for threading into the end of the body portion of rod 1. The stud is also threaded at the outer end 7 to receive the nut 8 which carries an abutment 9 of generally conical shape. The abutment 9 is formed complementary to a conically shaped abutment 10 provided generally centrally of the stud 5.

The cleaning cloth 3 has a central aperture for slipping the cloth over the outer threaded end 7 of stud 5 and is securely gripped between abutments 9 and 10 when nut 8 is threaded home. The conical shape of the abutments 9 and 10 at their complementary ends provides greater surface area for engagement with cloth 3.

In order to insure that cloth 3 will not slip when rod 1 is rotated in a gun barrel a plurality of grooves 11 of semi-circular shape are provided in the face of the conical shaped abutment 10 on stud 5. The grooves extend from the threaded end 7 of the stud to the outer periphery of 2,798,238 Patented July 9, 1957 abutment 10. The grooves shown are four in number and each groove is at right angles to the next adjacent groove around the circumference of the face of abutment 10. More or less grooves may be employed and at different angles than that shown. When nut 8 is threaded home to clamp cloth 3 between abutments 9 and 10 the cloth tends to move into the grooves 11 as shown in an exag gerated manner in Fig. 2 and is gripped against abutment 9 by the relatively sharp radial edges of grooves 11.

To further prevent slippage of cloth 3, a recess 12 is provided in the inner face of the abutment 9 of nut 8. The cloth tends to move down into recess 12 at the inside of grooves 11 and is clamped between the circular edge defining the recess 12 in nut 8 and the radial edges of grooves 11.

By clamping the cloth securely under the construction described the cloth is held against turning when the rod is rotated in a gun barrel. A better and more efiicient cleaning job can thus be done with the cloth.

The rod is jointed so that it can be disassembled into relatively short parts and the gripping means can also be disassembled to permit ready storage and transportation of the rod parts.

Various modes of carrying out the invention may be employed within the scope of the following claims which particularly point out and distinctly set forth the subject matter regarded as the invention.

I claim:

1. The combination of a cleaning rod and a patch holder connected to said rod to hold a cleaning cloth at the end of the rod for manipulation by the rod for cleaning a gun barrel or the like, said patch holder comprising a stud having an abutment and threads provided on the outer end of said stud outwardly of said abutment, a nut threaded onto the threads at the outer end of the abutment with said nut having an abutment thereon with a working surface complementary to the working surface of the abutment on the stud, one of said abutments having a recess encircling the stud and an outer rim for clamping the cleaning cloth against the opposite abutment when the nut is threaded home, and the other of said abutments having groove means provided in the working surface of the abutment with said groove means extending radially from the stud to the peripheral edge of said last named abutment and with the surface between the groove means being of substantial area and lying in a plane perpendicular to the stud, said cloth being drawn into said recess and into said groove means when the nut is threaded home with the edges of the groove means gripping the cloth and the substantially extended surface between the groove means preventing tearing of the cloth when the cloth is manipulated in service.

2. The combination of a cleaning rod and a patch holder secured to said rod to hold a cleaning cloth at the end of the rod for manipulation by the rod for cleaning a gun barrel or the like, said patch holder comprising a stud having threads on the inner end securing the stud onto the end of the rod and additional threads on the outer end, an abutment provided between the inner and outer threads of the stud, four grooves provided equidistant from each other in the surface of the stud facing outwardly of said rod with said grooves extending radially from the stud to the peripheral edge of the abutment and with the surface of the abutment between the grooves being generally extended and fiat and lying in a plane perpendicular to the stud, and a nut threaded onto the threads at the outer end of the stud and having an abutment thereon complementary to the abutment on the stud with a recess therein encircling the stud and an outer rim to clamp the cleaning cloth against the abutment on the stud when the nut is threaded home, said cloth being References Cited in the file of this patent UNITED STATES PATENTS Palmer Sept. 29, 1885 10 Lonsdale May 8, 1906 Howell Aug. 6, 1907 Hughes Apr. 9, 1912 Whoolery Nov. 5, 1912 Sebenius May 21, 1918 Arntz Oct. 9, 1923 Olberding Feb. 10, 1925 FOREIGN PATENTS Great Britain of 1903
