To all whom it may concern:
Be it known that I, James W. Leslie, a citizen of the United States, and a resident of Wakefield, county of Middlesex, State of Massachusetts, have invented an Improvement in Safety-Razors, of which the following description, in connection with the accompanying drawing, is a specification, like letters on the drawing representing like parts.
This invention relates to safety-razors and it has for its object the production of a simple, easily and cheaply constructed and efficient razor of the class referred to, the cutting blade being held in its operative position in a positive and accurate manner while permitting the ready removal from or insertion of the blade in the holder.
The various novel features of my invention will be fully described in the subjoined specification and particularly pointed out in the following claims.
I have herein shown the blade-holder as comprising a rigid back plate
On the back face of the blade I form a longitudinal rib or lip
The plates are rigidly and permanently connected by screws
The extremities of the blade are exposed at the back of the holder by the notches
When a blade becomes dull it can thus be readily removed for sharpening, and a fresh blade inserted in the holder, no setting or adjustment of the latter being required and hence I eliminate the chance of any part getting out of order or failing to perform its proper function.
The whole device is very simple, compact, and efficient, and it will be manifest that the two-part blade-holder can be made easily and cheaply and readily assembled.
The back of the blade rests against the shoulder
When the razor is in use the spring pressure of the lip of the front plate upon it holds it securely upon its seat on the back plate, preventing any accidental longitudinal displacement of the blade.
As the front plate extends across the notches
In the modification illustrated in
Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:—
1. A safety-razor having a rigid back plate provided with a transverse blade-seat and having teeth at its lower edge, a front plate rigidly secured to the back plate and having its lower edge pressed yieldingly toward the seat, said front plate being reduced in thickness transversely at its outer face to increase the resiliency of its lower edge, and a thin blade slidable sidewise between said plates onto the seat, the pressure of the lower edge of the front plate on the blade from end to end adjacent its cutting edge retaining the blade in place on the seat.
2. A safety-razor having a rigid nack plate toothed at its lower edge and provided with a transverse blade-seat having a recess adjacent thereto extending the length thereof, a rigidly attached front plate having its lower edge pressed yieldingly toward the back plate along its toothed lower edge, a thin blade slidable sidewise between said plates onto the seat and pressed upon the seat by the lower portion of the front plate acting thereupon adjacent its cutting edge and lugs on the blade to enter the recess adjacent the seat and position the blade thereon.
3. A safety-razor having a rigid back plate toothed at its lower edge and provided with a transverse blade-seat having a recess adjacent thereto and extending the length thereof, a rigidly attached front plate having its lower edge pressed yieldingly toward the back plate, a handle fixedly secured to the back plate, a thin blade slidable endwise between the plates, and lugs on the blade to enter the recess adjacent the seat as the blade is pushed into place, the cutting edge of the blade extending below the lower edge of the front plate, the pressure of the latter upon the blade adjacent its cutting edge holding it firmly on its seat.
4. A safety-razor comprising a blade-holder consisting of a rigid back-plate having a blade-seat, and a rigidly and permanently attached front plate extended over the seat and having a resilient lip adapted to press against the face of the blade adjacent its cutting edge and retain it on the seat, a blade movable sidewise into position on the seat, means to guide the blade in its sidewise movement on the seat, and a handle connected rigidly and directly to the back-plate.
5. In a safety-razor, a blade-holder consisting of a rigid back-plate having a toothed lower edge and a blade-seat on its front face, a handle attached to and substantially at right angles to the back-plate, and a fixedly attached front plate overhanging and completely covering the seat and having a resilient lower edge or lip adapted to press yieldingly upon the blade adjacent its cutting edge when the blade, is seated.
6. A safety-razor comprising a blade-holder consisting of a rigid back-plate having a blade-seat, a fixedly attached front plate overlying the seat and having a resilient lower edge to yieldingly press upon the face of the blade adjacent its cutting edge and force the blade onto the seat, a blade movable sidewise into position on the seat, and a longitudinal lip or rib on one of said parts to enter a guide groove formed in the other part, to govern the side-wise movement of the blade into operative position.
In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
