Description
i-Nmh 'l I -UNITED STATES PATENT OFFICE.,
FREDERICK KAMPFE, RICHARD KAMPFE, AND OTTO KAMPFE, OF i BROOKLYN, NEW YORK.
RAZO R-STRO P.
SPECIFICATION forming part of Letters 'Patent No. 477,902, dated June 28, 1892. Application led August 25, 1891. Serial No. 403,654. (No model.)
To all whom t may concern:
Be it known that we, FREDERICK KAMPFE, RICHARD KAMPFE, and OTTO KAMPFE, citizens ot' the United States, and residents of Brooklyn, in the county ot Kings and State of New York, have invented certain new and useful Improvementsin Razor-Strops, of which the following is a specification.
This invention relates to improvements in razor-strops; and the object of our invention is to provide a new and improved razor-strop which gives a sharp and keen edge to the blade without makingthe same too ragged, and thus adapting said edge to shaving both when the hair ou the face is coarseand when it is flue without in any way pulling or causing pain.
Our invention consists of a razor-strop made of leather and provided with a series of groups of oblique or diagonal grooves and intermediate ridges cut into the surface of the leather, said groups of intermediate grooves and ridges being separated by smooth parts of the surface of the leather.
In the accompanying drawings, Figure l is a face view of our improved razor-strop. Fig. 2 is a face View of a modification. Fig. 3 is an enlarged longitudinal sectional view on the line 3 3 0f Fig. l. Y
Similar letters of reference indicate corresponding parts.
The razor-strop A is made of leather, and on its face is provided with a series of groups B, of diagonal or oblique. grooves a., separated by the intermediate ridges b. The groups B of grooves and ridges are separated by spaces C of the face of the razor-strop, which are left blank-that is, the smooth surface of the leather appears so that the face of the strop will show alternately smooth spaces C and groups B of grooves and intermediate ridges. Said groups of' grooves and intermediate ridges rnay all be made parallel to each other, as shown in Fig. l, and are preferably arranged at an angle of about fortyive degrees; but, if desired, the alternate groups B of grooves and intermediate ridges and the blank spaces C between them may be inclined in opposite directions, as on the strop A shown in Fig. 2. t y
On the ordinary razor-strop made of leather or canvas the microscopic teeth of the razorblade are sharpened toward the ends only, but the side edges are not affected. By making a strop with inclined alternate grooves and ridges the side edges of said microscopic teeth are sharpened in addition to the points; but if the strop is provided with alternate grooves and ridges on its surface throughout its entire length the side edges of the 1nicroscopic teeth are sharpened to such an extent that the edges become too keen for a person having a tender skin and not verythick growth of hair. In order to obviate this defect, and yet to have the advantage of the said sharpened side edges of the microscopic teeth, the smoothL portions C have been arranged on the face of the strop to alternate with the grooved portions. In passing the blade over the strop the grooved portions of the strop sharpen the side edges of the microscopic teeth of the cutting-edge and give to the cutting-y edge a certain roughness, which is a great advantage in shaving a heavy growth of hair; but the smooth portions O of the strop take out this certain roughness from the cuttingedge wit-hout entirelydestroying the sharp edges of the side of the microscopic teeth. A razor stropped on a strop of this kind is then-adapted to eut a heavy beard on account of the sharp'side edges of the microscopic teeth and at the same time does not cut or pain a tender skin, as the smooth parts of the strop have eased off the great roughness of the side edges of the said microscopic teeth.
Having thus described our invention, we claim as new and desire to secure by Letters .Patentl. Aleather razonstrop provided on its face with alternate groups of smooth portions of In testimony that We claim the foregoing as the strop and with grooved portions,substan our invention we have slgned our names 1n tially as set forth. presence of two subscribing Witnesses.
