To all whom it may concern:
Be it known that I, William Greenfield, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Safety-Razors; and I do hereby declare the following to be a full, clear, and exact description of said invention, such as will enable others skilled in the art to which it most nearly appertains to make, use, and practice the same.
Safety-razors, so far as I am aware, have heretofore uniformly been made with the razor-blade and its guard permanently arranged across the end of the handle, with the razor-blade at right angles to the handle, so that they could only be used for shaving by moving the razor across the face lengthwise of the handle.
My invention relates to a novel construction for safety-razors by which the implement can either be used with a longitudinal movement, like the ordinary safety-razor, or, if desired, it can be adjusted to either side, so as to throw the razor and a portion of its handle to a right angle to the lower portion of the handle, and thereby carry the razor edge to a position parallel with the lower part of the handle, so that the implement can be grasped and used in shaving like an ordinary razor.
It also consists of a novel arrangement by which the razor-blade can be adjusted and secured to the end of the handle with its edge parallel with the handle, so that it can be honed or stropped like an ordinary razor.
Referring to the accompanying drawings,
The handle of my improved safety-razor I make in two principal parts, which are hinged together at their ends, so that they may be adjusted either in a straight line or shifted to a position at right angles to each other, as shown at
The lower part of the handle (marked
The upper part of the handle, as above stated, is composed of two parts, the upper part being the tang proper, while the lower part, which is marked
The razor or safety guard
A combined finger and latch bar
In order to hone or strop the razor, the razor-blade is first put in the position explained above and shown at
By this construction and arrangement I provide an exceedingly simple and convenient safety-razor that can be used by any person and by the same movement, if desired, as is used with an ordinary plain razor.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, is—
1. In a safety-razor; a jointed handle; and means for clamping and rendering the joint rigid when the jointed parts are in line; in combination with a razor-blade adapted to be secured either transversely across the end of the handle so as to be operated by a direct movement, or lengthwise with the handle so as to be operated as an ordinary razor; and means for fastening the blade to the handle in either position, substantially as described.
2. In a safety-razor; a jointed handle; means for clamping and rendering the joint rigid when the parts are in line; and means for latching the parts at a right angle to each other when the parts are thrown to a rectangular position; a razor-blade adapted to be secured either transversely across the end of the handle or lengthwise with it; and means for fastening the blade in either position, substantially as described.
3. In a safety-razor, a razor-blade having a portion of its back extending to the middle of the blade cut away and recessed on each side of the shoulder, in combination with a bifurcated tang or shank, which is adapted to fit against the shoulder in either a rectangular or parallel position, and means for securing them together in either position, substantially as described.
4. In a safety-razor, a razor-blade adapted to be removably secured to the end of a handle in a position parallel with the handle, means for fastening the blade to the handle, and means for preventing lateral displacement of the blade during the operation of honing or stropping, substantially as described.
5. In a safety-razor, a jointed handle; latching devices on each side of the lower part of the handle; and lever-arms on the upper jointed part of the handle adapted to engage the latching devices on the lower part of the handle when the parts are adjusted at a right angle to each other in either direction, substantially as described.
6. In a safety-razor, a razor-blade adapted to be secured to the end of a tang or shank at right angles to or parallel with the handle; a short tubular section adapted to receive the opposite end of the tang or shank; a spring inclosed in said short tubular section; means for holding the end of the tang or shank in contact with the upper end of the spring and permit the pressure on the tang or shank to act upon the spring; a handle or lower section connected with the short tubular section by a joint; means for rendering said joint rigid, and latching devices, which secure the parts at a rectangular position when the jointed parts are adjusted to a right angle, substantially as described.
In testimony whereof I have hereunto signed my name, in the presence of two witnesses, this 18th day of June, A. D. 1897.
