To all whom it may concern:
Be it known that I, Robert M. Keating, of Springfield, in the county of Hampden and State of Massachusetts, a citizen of the United States, have invented certain new and useful Improvements in Safety-Razors, of which the following is a specification.
The object of my invention is to provide a new and improved safety-razor, which is simple in construction, in which the blade is held securely, and can be adjusted very nicely on the guard.
The invention consists in the combination, with spring side jaws, of a screw for drawing them toward each other and a blade-retaining hook or catch on said screw.
The invention also consists in the construction and combination of parts and details, as will be fully described and set forth hereinafter.
In the accompanying drawings,
Similar letters of reference indicate corresponding parts.

Having thus described my invention, I claim as new and desire to secure by Letters Patent—
1. In a safety-razor, the combination of two spring side jaws, a guard, a screw for drawing the guards toward each other, and a retaining-hook on said screw, substantially as herein shown and described.
2. In a safety-razor, the combination of two side jaws having grooves for receiving the ends of a removable blade, a guard held on said side jaws, a spindle having a screw-threaded end passed through a threaded aperture in one jaw, and its opposite smooth end passed through a smooth or plain aperture in the other jaw, a thumb-piece on the one end of the spindle, and a retaining-hook secured on the spindle between the jaws, substantially as herein shown and described.
3. In a safety-razor, the combination of two side jaws having slots, a guard having end lugs passed through said slots, and screws screwed through the bottom edges of said jaws for locking the guard in place, substantially as set forth.
4. In a safety-razor, the combination of side jaws having slots, a guard having end lugs passed through said slots, screws for locking the guard in place, said guard having a longitudinal gage-mark on its upper surface, substantially as herein shown and described.
5. In a safety-razor, the combination of the side jaws
In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
Robert M. Keating.
