IMPROVEMENT IN RAZOR-STROPS.

Spccijlcctiouformlng part of Lett-ers Patent No. 93,091, dated July 27, 1869.

To all whom lt may concern Be it known that I, JAEEZ JENKINS, of Philadelphia city and county, in the State of Pennsylvania, have invented certain new and useful Improvements in Razor-Strops; and I hereby declare the following to be a full and may be made of wo( d, or other suitable material, and upon the iiat sides of this I fasten, by cement or otherwise, sheets of cork, B B.

Ithen prepare the surface of one of'thcse sheets by the following process: Itake india-rubber varnish, made by dissolving about two ounces of pure gum lin about one gallon of benzine, and to one part,.by measure, of this varnish I add about two parts of spirits of turpentine, which prevents its drying too suddenly, so as to allow of a more even and perfect distribution' ot' it when applied to the strop. Into this liquid I stir very fine our of emery till the mixture has the consistency of cream, and then apply a coating ofit to the cork surface by means of a brush.

When this is fully dry, I take a flat piece of glass or metal, preferably of glass, having one straight edge cut off evenly and smoothly, at right angles, or nearly at right angles, to the Hat surface, so as to form an even'and sharp corner or edge, and applying the at surface of this scraper to the surface of the strop, varnished as above described, and pressing on it, I urge it forward repeatedly upon the strop, the edge or corner before mentioned being foremost, and taking off, as

a scraper, not only all projections above the general surface, but also the coarser or more prominent particles of emery, and preparing a very smooth and even surface for the delicate edge of the razor. Then, to keep this preparation in place more securely, I spread over ita thin coating of the varnish before described, either with or without the addition of turpentine, as may .be preferred.

The fine particles" of emery work through this outer coating of Varnish under the pressure of the razor, and both the varnish and cork being elastic, and giving somewhat under the pressure of the edge, the sharpening action of the material is evenly and most efficiently applied.

The obvious advantages resulting from this process are great evenness', elasticity, and efficiency, together with remarkable durability or permanence, the preparations in which grease is employed being, it is well known, extremely liable to get out of order by reason of the grease being taken off on the razor, or absorbed by the strop.

On the opposite side I leave the surface of v the cork barefor a nishing-side, upon which the strapping is to be completed after the use of the prepared side. i

Ihese strops may be made of four or any other number of sides, some covered with the preparation above described, and others not, and emery of different grades of neness may be employed-for different sides, if deemed advisable.

I do not claim, broad-ly, arazorstrop with a cork surface but A razorstrop with a cork surface, when coated with the composition described, as a new article of manufacture.
