To all whom it may concern:
Be it known that I, Carl R. Evertz, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Razor, of which the following is a full, clear, and exact description.
The object of this invention is to provide a razor stock with a detachable blade, and furnish means for a quick and secure connection of the blade with the stock or back piece, and which will also permit the blade to be removed readily and safely for interchange with any of a series of similar blades.
To this end my invention consists in the construction and combination of parts, as is hereinafter described and claimed.
Reference is to be had to the accompanying drawings forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.
The stock or back piece
Preferably the stock
On the edge of the spacing strip
The razor blade
It is contemplated to furnish a set of blades
The parts of this improved device when assembled for use, lock the blade removably in the stock, and provide a strong, neat and convenient razor, that has no projections to interfere with its free use, or catch on other articles.
The similar blades of the razor as formed, may be rapidly shaped with dies, that will cut the tongues on their edges at one stroke, so that these parts can be cheaply produced, as well as the parts of the stock that are produced in a like manner.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is—
1. In a razor, the combination with a grooved stock, a blade fitting the stock groove, hooks on the blade which interlock with projections on the base of the stock groove when slid forwardly in said groove, and a plain lever dog pivoted in the stock groove and adapted to impinge its free end on the rear edge of the blade when said blade is fully inserted, substantially as described.
2. In a razor, the combination with a longitudinally grooved stock, hooked tongues on the base of the stock groove and forwardly projected, and a razor blade having hooks formed on one edge that mate the tongues in the stock groove and adapted to interlock therewith when the blade is slid in the stock groove from the rear forwardly, of a lever dog pivoted by one end in the stock groove behind the blade and pressed by the spring back of the stock, and a handle pivoted to fold on the stock, substantially as described.
3. In a razor, the combination with a stock composed of two sides, a spacing strip between said sides adapted to form a spring back for the stock, hooked tongues on said strip that point forwardly on the stock, and a spacing strip at the heel of the stock all secured together to produce a longitudinal groove in the stock, of a razor blade fitted in the stock groove, hooks on the blade produced by spaced notches formed in the back edge of the blade and adapted to interlock with the tongues on the spring back strip of the stock when slid forwardly in the stock groove, a lever dog pivoted to fold in the stock groove at the rear of the blade and be fully embedded therein, its free end abutting upon the blade's rear end when said dog is in folded adjustment, and a folding handle pivoted on the stock, substantially as described.
