To all whom it may concern:
Be it known that I, Oscar C. Williams, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Safety-Razor, of which the following is a specification, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon.
This invention relates to a safety razor having a plurality of cutting edges and guards therefor, more particularly a blade having a plurality of cutting edges, and a guard plate keyed to the blade and having a plurality of guard sides or edges corresponding in number to the cutting edges of the blade; the invention having reference more particularly to a safety razor provided with a plurality of cutting edges and also a frame and a handle adjustable to various positions relatively to the shaving blade to permit the razor to be variously used.
An object of the invention is to provide a safety razor that shall be so constructed as to enable the razor to perform its functions many times or for long periods without requiring re-sharpening or renewing of the blade.
Another object is to provide a safety razor which shall be so constructed as to have a single blade with the maximum number of cutting edges so as to permit of economical construction and saving of time in the changing, re-sharpening and handling of the blades.
A further object is to provide a safety razor of such construction as to permit the razor to be used in various ways, as by drawing it, or pushing it, or moving it sidewise.
A still further object is to provide a safety razor which shall be so constructed as to have a quickly-adjustable handle and a quickly-adjustable frame, of simple and inexpensive character, to enable the razor to be used in various ways, especially as may be desired on faces on which the beard or hairs lean in various directions.
With the above-mentioned and other objects in view, the invention consists in a frame of novel construction having a handle adjustable thereon, and a guard plate and a razor blade of novel construction and adjustably connected to the frame; and, the invention consists also further in the parts and combinations and arrangements of parts as hereinafter particularly described and further defined in the accompanying claims.
Referring to the drawings,—
Similar reference characters in the different figures of the drawings indicate corresponding elements or features of construction herein referred to in detail.
As preferably constructed the razor is provided with four cutting edges and also a guard plate having four guard sides or edges, the blade and the plate being keyed or locked together; and so constructed the razor is provided with a metallic guard plate
A rectangular or squared razor blade
A clamp plate
A novel frame is provided which preferably is composed of suitable sheet metal and shaped to constitute a base plate having an approximately flat and straight portion
As the various parts of the safety razor are assembled the base plate of the frame is arranged upon the guard plate
In practical use the handle
Having thus described the invention, what is claimed as new is—
1. A safety razor comprising a rectangular guard plate having four fingered guards and also a central aperture and a socket, a rectangular blade having four cutting edges and also a central aperture and a socket, a clamp plate that is rectangular in plan and having a stud central thereon and extending through the apertures in the blade and the guard plate, the clamp plate having also a dowel thereon that extends through the sockets in the blade and the guard plate, said stud having a head thereon, a frame comprising a curved base plate having a concave side arranged on the guard plate and a curved arm extending from the edge of the base plate and over the outer or convex side of the base plate, said base plate having a slot receiving said stud, the convex side of said base plate engaging the head of said stud, and a handle adjustably connected to the curved arm.
2. A safety razor comprising a guard plate having a central aperture and also four relatively rectangular fingered guards, a rectangular blade having a central aperture and also four cutting edges, a clamp plate provided with a central stud having a head on its end, the stud extending through the apertures in the guard plate and the blade, a frame having an elastic base that has a concave side seated at its edge on the guard plate and having a slot extending from one portion of its edge, the slot receiving said stud to enable it with its head to secure the frame base rotatably on the guard plate and to clamp the blade to the guard plate, the frame base being on a portion of its edge provided with a handle arm, and a handle adjustably connected to the handle arm.
3. In a safety razor, the combination with a guard plate having a plurality of fingered guards, and a blade connected to the guard plate and having a plurality of cutting edges, of a clamp plate having a stud central thereon and extending centrally through the blade and the guard plate, the stud having a head thereon beyond the guard plate, a frame comprising a curved base plate having a concave side arranged on the guard plate and a curved arm extending from the edge of the base plate and over the outer or convex side of the base plate, said base plate having a slot therein receiving said stud, the convex side of said base plate engaging the head of said stud, said arm having a slot therein, a handle adjustable on the convex side of said arm, and a securing screw extending through the slot in said arm and into said handle, said screw having a head engaging the concave side of said arm.
In testimony whereof I affix my signature in presence of two witnesses.
