Patented July 5, 1932 UNITED STATES PATENT OFFICE ANTHONY ABRANATHY, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR OF ONE-HALI TO ANTHONY GRIGAL, F PHILADELPHIA, 'PENNS YLVANIA STROP Application filed March 13, 1930. Serial No. 435,603.

This invention relates to improvements in strops for razors and cutting blades in general, and the principal object of the invention is to provide a strop which shall be generally more eflioient than strops of the prior known forms.

The invention resides in a novel structural formation, as hereinafter set forth, affording a stropping surface, the effectiveness of which for the intended purpose exceeds that of the prior devices of the same class.

In the attached drawing:

Figure 1 is a view in perspective of a strop made in accordance with my invention;

gig. 2 is a section on the line 2-2, Fig. 1,

Figs. 3, 4: and 5 are views in perspective illustrating certain of the steps in the manufacture.

With reference to Figs. 1 and 2 of the drawing, my strop in a preferred form comprises the usual elongated strip 1 of leather affording a flat relatively smooth stropping surface. Contrary to the usual practice, however, the efiective stropping surface of the strip 1 is provided with a plurality of inserts 2, these inserts preferably being relatively small and closely arranged in uniform pattern, substantially as illustrated. The

an exposed surfaces of the inserts 2 preferably are flush with the surface of the strop so that the usual flat substantially smooth surface is afforded, this surface, however, differing from the stropping surfaces of the usual strop by reason of having interspersed areas of different textures. which greatly increases the effectiveness of the stropping surface and the efficiency of the strop as a whole.

For the inserts 2, I have found leather admirably suited. The inserts may be readily formed as illustrated in Figs. 3, a and 5, by cutting a hide 3 into narrow elongated strips 4: of substantially rectangular cross section and drawing said strip through a suitable die (not shown) in order to remove the longitudimented to the strip 1.

nal corners and to form a substantially cylindrical strip 5, see Fig. 5, the cross sectional dlmensions of which are somewhat larger than the perforations or recesses formed in the strip 1 for reception of the inserts. Thereafter, an end of the strip 5 may be force fully inserted in the various holes and severed at the surface of the strip 1 to give the general construction illustrated in Fig. 1. Thereafter, the surface of the strip 1 may be finished to substantial smoothness by rubbing or in any desired manner.

It will be noted that the insert strip 5 is so formed from the leather blank 3 that the exposed faces of the inserts 2 are cut across so the grain of the leather whereby the texture of the inserted plugs differs from the texture of the face of the strip 1 which lies with the grain, and whereby the effective stropping surface is composed of the differing textures, 5 as set forth above.

By reference to Fig. 2, it will be noted that in the preferred embodiment of the strop illustrated, the cylindrical perforations formed in the strip 1 for reception of the inserts 2 ex- I tend completely through the said strip, and that the rear face of the strip is formed by a covering strip. 6 which preferably is ce-' The cement or adhesive used in applying the strip 6 also an- 1 5 chors the inserts 2 in the strip 1, although such anchorage is not necessary where the oversize of the insert blank 5 with respect to the insert apertures is such as to afiord a strong frictional grip. EU

I have discovered that the cross-grain surface of leather is a more efficient stropping surface than the normal face of the leather as usually employed in razor and other strops.

I have found further that a judicious combination of the cross-grain and normal surfaces of leather in a stropping surface, as herein described, affords particularly satisfactory results in the stropping operation. It will be understood that the invention is not restricted to the single embodiment herein illustrated, since the principles of the invention may be embodied in strops differing materially from the particular one herein illustrated.

I claim:

1. A razor strop comprising a strip of leather affording an extended stropping surface, said surface having inserted therein a plurality of plugs of leather the exposed surfaces of which extend across the grain of the leather and are substantially flush with the surface of the holding strip.

2. A strop having an effective stropping surface having interspersed areas of normal and cross-grain leather.

ANTHONY ABRANATHY.
