To all whom it may concern:
Be it known that I, Louis Heckel, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented a new and useful Safety-Razor-Blade Holder, of which the following is a specification.
This invention relates to safety-razors, and has for its principal object to provide a novel form of blade holder or clamp formed of a number of sections which when assembled with the blade in position will present a composite blade of the same shape and size as the blades used in the well-known “Star” and “Gem” type of safety-razor.
A further object of the invention is to provide a holder of this class which may be readily opened for the purpose of adjusting the position of the blade proper or for the renewal of the blade, and, further, to so arrange and construct the device that it may be employed as a substitute for the usual razor-blade employed in the frames of the type above mentioned and which may be placed in position in the ordinary stropping devices generally employed in connection with this type of razor-blade.
With these and other objects in view, as will more fully hereinafter appear, the invention consists in certain novel features of construction and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions, size, and minor details of the structure may be made without departing from the spirit or sacrificing any of the advantages of the invention.
In the accompanying drawings,
Similar numerals of reference are employed to indicate corresponding parts throughout the several figures of the drawings.
In one type of safety-razor now in common use the blade is formed of a short section of an ordinary razor-blade, its opposite sides being hollow-ground, and the back of the blade is arranged to slide within a suitable frame having guards to prevent accidental cutting of the skin while shaving. In another type of razor now in use the blades are formed of short flexible sheets or strips of steel having two cutting edges, and these blades require a special form of holding and clamping mechanism.
It is the object of the present invention to provide a means whereby the flexible two-edged blades may be used in connection with the frames and stropping devices of the first-named type.
In the drawings,
When the several parts are assembled, the device as a whole may be placed in any form of holder or frame that will receive a blade of the type used in the “Star” or “Gem” safety-razor, and it may be removed therefrom and placed in the stropping mechanism and holding mechanisms ordinarily employed for such blades.
It will readily be seen that by the employment of a clamp or holder of this type the thin two-edged blades now on the market may be successfully employed in frames of existing types and without the necessity of employing any special form of holder or carrier.
Having thus described the invention, what is claimed is—
1. In a device of the class specified, a pair of clamping-strips of gradually-increasing thickness from the front toward the rear edge, and provided with interfiling pins and openings, the outer faces of the strips being recessed, and a channeled back-piece fitting over the recessed portions of the strips, the outer surface of the back being practically continuous with the outer faces of the strips, the device as a whole being of a contour similar to that of a short section of an ordinary razor-blade.
2. A sectional clamp comprising a pair of blade-engaging strips, and provided with interfitting pins and openings to secure the blade to the strips, the outer faces of which are tapered from front to rear, the rear portions of the outer faces of the strips being recessed, defining a pair of shoulders extending lengthwise of the strips and parallel with the edges thereof, and a channeled back-piece fitting over the rear edges of the shoulders and having its opposite edges bearing against said shoulders, the outer face of the strip being continuous with the outer faces of the blades.
3. A sectional blade-clamp of a contour in cross-section similar to that of an ordinary razor-blade and comprising a pair of strips tapered in thickness from outer edge toward their rear edges, and provided with interfitting pins and holes, the outer faces of the rear portions of the strips being provided with recesses terminating in shoulders that extend from end to end of the strips and parallel with the two edges thereof, the lower walls of the recesses being disposed at a slight angle to the plane of the inner faces of the strips, and a channeled back-piece fitting over the recessed portions of the strips and provided at one end with a flange or wall to limit movement of said back-piece with respect to the strips.
In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
