To all whom it may concern:
Be it known that I, Leonard B. Gaylor, a citizen of the United States, and a resident in the city of Stamford, county of Fairfield, State of Connecticut, have invented a new and useful Improvement in Safety-Razors, of which the following is a specification, reference being had to the accompanying drawings, in which—
The new features of my invention are its exceeding simplicity, durability, and inexpensiveness, together with the fact that the great advantage of the shearing cut in either direction, which may be had at any desired angle, as well as the square cross-cut, are additionally obtainable.
The blade, as shown, is three-cornered, conforming to the shape of the guard-plate, and is preferably made of such thickness as to be rigid without elasticity, because since it has no backing plate or other means to support it it should have the requisite stiffness to withstand the pull of a coarse beard when in use. I therefore wish to avoid flexibility. I also prefer non-flexible blades, because I gain the advantage that they can be manufactured from a thickness of sheet-steel, which is not only easily procured, but can be uniformly hardened or tempered without unusual manufacturing difficulty, which obtains in the manufacture of thinner sheet-steel.
The corners of my blade, as shown at
From the above description the operation is obvious. To remove a dull and insert a sharp blade, all that is necessary is to unscrew the knurled thumb-nut, whereupon the parts will immediately separate, as shown in
Furthermore, as illustrated in
It will be obvious to those who are familiar with this art that modifications may be made in the details of construction without departing from the essentials of the invention. I therefore do not limit myself to such details.
1. A safety-razor embodying a handle, a centrally-perforated guard-plate, a blade having a single perforation therein and a thumb-nut adapted to pass through the perforations in the blade and guard-plate and thread into the handle, the guard-plate having protecting devices at its corners engaging with the corners of the blade, whereby the edges of the blade are registered with the edges of the guard-plate.
2. A safety-razor embodying a handle, a triangular guard-plate provided at its corners with protecting and registering devices for the corners of the blade, a triangular blade adapted to coact with the guard-plate and registering devices thereon, and means to detachably connect said members together.
3. In a safety-razor, a triangular guard-plate having at each corner protecting and registering devices for the blade which project laterally beyond the plane of the guard-plate and a triangular blade which lies against said guard-plate, its corners being received within and protected by said registering devices.
4. A safety-razor having a triangular flat guard-plate, a triangular flat blade, lying one against the other, the blade having three cutting edges, and the guard-plate three comb-like edges, and also upturned corners registering with the corners of the blade and means to detachably connect the parts together.
5. A safety-razor comprising a handle, a triangular guard-plate, a triangular blade having its edges adjacent to the corresponding edges of the guard-plate, and means for movably securing the guard-plate and blade upon the handle to enable the handle to be adjusted at varying angles with respect to all the edges of the blade and guard-plate.
6. A safety-razor comprising a handle, a triangular guard, a triangular blade located against the guard, means to register the blade upon the guard-plate to maintain the edges of the blade in correlation to the corresponding edges of the guard-plate, and means for movably securing the guard-plate and blade upon the handle to permit the handle to be adjusted to various angles with respect to the edges of the blade while the corresponding edges of the blade and of the guard-plate are maintained in operative relation to each other.
7. A safety-razor comprising a handle, a guard having three edges located at angles to each other, a blade having three edges located at angles to each other and corresponding to the edges of the guard, means to register the blade upon the guard to maintain their edges in operative correlation and means for rotatably connecting the guard and blade with the handle.
8. A guard for a safety-razor having three edges at an angle to each other provided with comb-like teeth and protecting devices at the corners of the guard, in combination with a triangular blade the corners of which coincide with and are protected by said protecting devices on the guard.
9. In a razor a blade, a triangular guard having comb-like edges and having also at its corners protecting devices which engage the blade and hold its edges in operative position relative to the edges of the guard.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
