To all whom it may concern:
Be it known that I, Lyman H. Cobb, a citizen of the United States, residing at Fitchburg, in the county of Worcester and Commonwealth of Massachusetts, have invented a new and useful improvement in a Safety-Razor, of which the following is a specification, accompanied by drawings forming a part of the same, in which—
Similar reference letters and figures refer to similar parts in the different views.
My present invention relates to an improved means of holding the cutting blade in a safety razor by which the cutting blade may be instantaneously released, and I accomplish this result by the construction and arrangement of parts as hereinafter described and pointed out in the annexed claims.
Referring to the accompanying drawings
The end of the handle is cut away on opposite sides as shown in perspective view in
In
In order to insert a cutting blade it is held by the wings
I claim,
1. In a safety razor, the combination with a handle, of a bed plate for supporting a cutting blade, a clamping plate for holding the cutting blade against the bed plate, said clamping plate being provided with a lug parallel with said bed plate, and a spring between said lug and said bed plate.
2. The combination in a safety razor, of a handle, a head supported on one end of said handle, and comprising a spring actuated clamping plate, and a bed plate for holding a cutting plate, said handle having a curved section between the body portion of the handle and the head.
3. The combination in a safety razor, of a handle, a bed plate attached to one end of said handle for supporting a cutting blade, said handle having a curved section adjacent to said head, whereby said head is held at an oblique angle to the axis of said handle, and with the axis of said handle extended passing through said head between the cutting edge of the blade and the end of the handle.
4. The combination, in a safety razor, of a handle, a bed plate attached to the end of said handle, a clamping plate, bent over one edge of said bed plate and having a lug parallel with said bed plate, and a spiral spring between said lug and said bed plate, with its tension applied to draw the clamping plate toward said bed plate.
5. In a safety razor, the combination of a bed plate for supporting a cutting blade, a clamping plate for holding the cutting blade against the bed plate, and a spring operatively connected with both of said plates and arranged to draw said plates together.
6. In a safety razor, the combination of a bed plate, a clamping plate on one side of said bed plate, a lug carried by said clamping plate and extending on the other side of said bed plate, and a spring interposed between said lug and said bed plate to draw the clamping plate toward the bed plate.
7. In a safety razor, the combination of a bed plate, a clamping plate bent downwardly over the rear edge of said bed plate, then rearwardly and forwardly to form a lug parallel with the clamping plate, and having an increased surface to receive pressure in releasing the cutting blade, and a spring interposed between said lug and said bed plate to draw the clamping plate toward the bed plate.
8. In a safety razor, the combination of a handle, a bed plate attached to said handle, guard teeth on one edge of said bed plate, prongs at the ends of said bed plate, a cutting blade having notched ends engaging said prongs to hold the edge of the blade in registration with said guard teeth, a clamping plate and a spring applied to hold said clamping plate against the cutting blade.
Dated this twenty sixth day of September 1906.
