To all whom it may concern:
Be it known that I, Walter J. Smart, a citizen of the United States, residing in the borough of Brooklyn, in the city of New York and State of New York, have invented a new and useful Improvement in Cutting-Blades for Razors, of which the following is a specification.
This invention relates to safety razors of the type disclosed in my pending application, Serial No. 241,129, filed January 14, 1905, of which the present application is a division.
The objects of the invention are to improve and simplify the construction of the razor frame and blade; furthermore, to increase their efficiency in operation, and to decrease the expense attending their manufacture and use.
With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of the following claims without departing from the spirit of the invention.
In the accompanying drawing forming part of this specification,
Like reference characters indicate corresponding parts in the different figures of the drawing.
The improved blade which I prefer to use in connection with the razor of the present invention is designated by the reference letter
The razor construction which I prefer to employ comprises a curved razor frame
The means for holding the pivotal retaining member
The end projections of the blade
Having described my invention, I claim,
1. As a new article of manufacture, a thin, flexible, approximately-rectangular blade having a forward cutting edge and end projections located close to said cutting edge, substantially as described.
2. A safety razor having a guard, a clamping member provided with downwardly bent lugs pivotally connected with said guard and a flat blade having end projections abutting against the lugs of said clamping member, substantially as described.
3. A safety razor having a guard, a clamping member provided adjacent the forward edge thereof with downwardly bent lugs pivotally connected with said guard, and a flat blade having end projections extending beyond the ends of said guard and resting against the lugs of said clamping member, said blade being fitted between said guard and said clamping member, substantially as described.
4. A safety razor having a guard, a clamping member having downwardly bent lugs adjacent the forward edge thereof, said lugs being pivotally connected with said guard adjacent the guard teeth thereof, said clamping member having a rearwardly extending finger-piece, a coil spring interposed between said guard and the finger-piece of said clamping member, and a thin flat blade interposed between the clamping member and the guard and having end projections extending beyond the ends of the guard and engaging the downwardly bent lugs of the clamping member.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
Walter J. Smart.
