No. 416,461.Patented Dec. 3, 1889.
United States Patent Office.

Robert M. Keating, of Springfield, Massachusetts. Safety-Razor.
SPECIFICATION forming part of Letters Patent No. 416,461, dated December 3, 1889. Application filed March 15, 1889. Serial No. 303,445. (Model.)

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, Figure 1 is a rear view of my improved safety-razor. Fig. 2 is a cross-sectional view of the same. Fig. 3 is a top view of the same.

Similar letters of reference indicate corresponding parts.

The two side jaws A are made integral with the spring-shanks B of the handle C,and each side jaw is provided on its top edge with an inwardly-projecting flange D. To the inner side of each side jaw a plate F is secured, forming a shoulder F′, on which the under side of the blade E rests, said shoulders F′ and the under sides of the flanges D forming grooves W for receiving the ends of the blade E, said grooves tapering from the rear toward the front of the blade-holder; so as to about conform to the cross-section of the blade E. Each side jaw A is provided at the front end with a slot G, extending from front to rear, and through the said slots the end lugs H of the L-shaped notched or slotted guard J are passed. Said end lugs also pass through slits or notches G′ in the front parts of the plates F, and said lugs and the guard can be locked in place by means of the screws L, passed through the bottom parts of the plates F at their front ends. The guard J is provided on its top with the longitudinal gage-mark M, for adjusting the guard to the edge of the blade E.

A spindle N is passed through the two side jaws A, the left-hand end of the said spindle being screw-threaded, and the aperture in the left-hand side jaw, through which the spindle is passed, is also screw-threaded. The right end of the spindle is smooth and passes through a smooth aperture in the right-hand side jaw, and on the right-hand end of the spindle a thumb-piece O is secured and rests against the outside of the said right-hand side jaw. A blade-retaining hook P is secured on the spindle N between the side jaws.

The spindle N is turned so as to swing down the hook P, and thereby the screw-spindle is screwed or moved toward the right—that is, screwed out of the left-hand side jaw—permitting the side jaws to separate under the action of their spring-shanks. The ends of the blade E are then passed into the grooves W, formed at the inner surface of the side jaws, and then the spindle N is turned to swing the hook P against the back or rear edge of the blade, which is thus held and locked in place.

By turning the spindle so as to swing up the hook P it is screwed farther into the left-hand jaw A, and thereby the jaws are moved toward each other and pressed against the ends of the blade, so as to prevent all longitudinal shifting of the same.

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 A, having the slots G, the plates F, having the notches G′, the screws L in the plates F,and the guard. J, having the end lugs H passed through the slots G and notches G′, substantially as herein shown and described.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.

Robert M. Keating.
