To all whom it may concern:
Be it known that I, John H. Hilton, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Razor and Guard, of which the following is a full, clear, and exact description.
The object of the invention is to provide a new and improved razor and guard arranged to permit convenient adjustment of the guard relative to the cutting edge of the blade and to allow removal of the blade when worn down too far for the guard to be effective and the substitution of a new blade for the worn-out one.
The invention consists of novel features and parts and combinations of the same, as will be more fully described hereinafter and then pointed out in the claims.
A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.
On the handle
The guard for the razor is provided with sets of clamping-jaws
The clamping-jaws
Now when the cutting edge of the blade
Having thus described my invention, I claim as new and desire to secure by Letters Patent—
1. A razor provided with a back having a longitudinal recess, a pin in the back, extending across said recess, a blade received into said recess and having an inclined slot extending from the back of the blade toward the edge thereof, through which slot said pin passes, whereby a longitudinal movement of the blade in said recess in the direction of the open end of said slot will bring the top edge of the blade into abutting engagement with the upper wall of said longitudinal recess, and means for locking said blade and back together when in that position.
2. A razor provided with a back having a longitudinal recess, a pin extending transversely in the back through the said recess, a blade having an inclined slot for engagement by the said pin, and a catch on the end of the back, for locking the blade against outward movement, the said catch having a threaded shank screwing longitudinally in the back, as set forth.
3. A razor provided with a back having a longitudinal recess, a pin held in the back and extending transversely through the said recess, a blade having an inclined slot and a rounded-off forward end at the back portion, the cutting portion of the blade extending beyond the outer end of the blade's back, the said inclined slot engaging the said pin, and a catch mounted to swing on the outer end of the said back and adapted to engage the outer end of the back of the blade, as set forth.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
John H. Hilton.
