Description

'. 1, 1942. F, N. LUCIANO RAZOR SHARPENER Filed June 13, 1942 Inventor Attorneys Patented Dec. 1, 1942 UNITED STATES PATENT QFFICE RAZOR SHARPENER Frank N. Luciano, Jersey City, N. J.
Application June 13, 1942, Serial No. 446,926
1 Claim.
The invention relates to improvements in sharpening means for straight razors or any similarly edged tool requiring stropping action for production and finishing of the desired cut ting edge, and the primary object of the invention is to provide sharpening means of this character which enables more uniform, accurate, and quicker stropping, the said means being relatively unaffected by climatic changes or by changes in temperature.
Other important objects and advantages of the invention will be apparent from a reading of the following description taken in connection with the appended drawing, wherein for purposes of illustration preferred embodiments of the invention are shown.
In the drawing Figure 1 is a general top perspective view of a two-ply embodiment.
Figure 2 is an enlarged end elevational view of Figure 1,
Figure 3 is a top perspective view of a threeply embodiment of the invention.
Figure 4 is an enlarged end elevational view of Figure 3.
The device of the invention can be used in place of a leather strop such as is usually used to sharpen and finishing cutting edges of straight razors and similar tools. In using the device of the invention the razor is stropped in the same manner as with a leather strop, several light back-and-forth strokes across the top of the device usually being sufficient to restore and finish the dulled cutting edge of the razor. The device of the present invention is not intended for honing a razor or other similar tool.
Referring in detail to the drawing and first to Figures 1 and 2 thereof constituting the two-ply embodiment of the invention, the device, generally designated 5 consists of an elongated rectangular plate 6 of hardwood, to the top of which is glued or otherwise cemented a similar block or plate 1 of balsa wood.
The relative porosity of the balsa wood not only acts to resist agencies otherwise producing warping and swelling, but also provides excellent anchorage for a coating 8, on the balsa wood block of suitable abrasive and lubricating material such as a mixture of zeolite and tallow.
Referring to the three-ply embodiment of the invention shown in Figures 3 and 4, generally designated 5a, the device consists of a hardwood block 611. to the upper and lower sides of which are glued or otherwise cemented the coated balsa wood blocks la, whereby two separately usable stropping surfaces are provided.
The coating material is a paste made from substantially one part of a mixture of tallow and'zeolite, now marketed as Zeolithe, and one part of alcohol.
Although there are shown and described herein preferred embodiments of the invention, it is to be understood that the invention is not limited thereto except as may be provided for in the subjoined claim.
Having described the invention, what is claimed as new is:
A device of the character described comprising a relatively dense, rigid and imperforate base plate, at least one stropping block secured along the side of the base plate, said block being of relatively soft, substantially porous wood, and a coating on said block of combined abrasive and lubricant, said base plate being formed of hardwood and said block being formed of balsa wood, said combined abrasive and lubricant consisting of a mixture of zeolite, tallow and alcohol.
