To all whom it may concern:
Be it known that I, Henrie Clauss, a citizen of the United States, residing at Fremont, in the county of Sandusky, State of Ohio, have invented certain new and useful Improvements in Safety-Razors; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.
This invention relates to new and useful improvements in safety-razors; and it consists in the construction and arrangement of parts hereinafter fully set forth, and pointed out particularly in the claims.
The objects of the invention are to produce a razor of the class described wherein the parts are all connected, obviating the liability of losing any of said parts.
A further object is to provide for quickly opening and closing the razor for the removal and insertion of the blade.
A further object is to provide for locking the razor open, permitting all of the parts to be easily cleaned.
A further object is to provide for locking the razor closed and for bringing any desired pressure upon the blade to hold it firmly in place.
A further object is to provide for employing a thin or a heavy blade in the razor, as desired.
The above objects are attained by the structure illustrated in the accompanying drawings, in which—
Referring to the characters of reference,
The top plate
The lower end of the rod
Projecting from the plug
To lock the razor closed and to place additional stress upon the plate
To press the blade properly into place against the stop-lugs
Having thus fully set forth my invention, what I claim as new, and desire to secure by Letters Patent, is—
1. In a safety-razor, the combination with the support and guard, a handle attached to said support, a hinged top plate adapted to clamp the blade to the support, a vertically-reciprocatory rod for manipulating said hinged plate, and means for locking said rod against movement.
2. In a safety-razor, the combination of the blade support and guard, a hollow handle attached thereto, a hinged top plate adapted to clamp the blade to the support, means located in the hollow handle and attached to said hinged top plate for actuating it, and means for locking said plate-actuating means.
3. In a safety-razor, the combination with the blade-support and handle, of a hinged top plate adapted to clamp the blade upon said support, a vertically-reciprocatory rod pivoted to said hinged plate and lying within the handle, a spring engaging said rod to normally hold said plate closed, means for moving the rod longitudinally to open and close said plate, and means for locking the plate open.
4. In a safety-razor, the combination with the blade-support and handle, of a top plate hinged to the blade-support, a reciprocatory rod passing through the handle and pivoted to said hinged plate, a spring engaging said rod to exert a downward pressure thereon, and means for locking said rod to hold said plate closed.
5. In a safety-razor, the combination with a blade-support, of a handle, a hinged clamping-plate adapted to hold the blade upon said support, a rod passing through the handle and pivoted to said clamping-plate to actuate it, means for moving said rod vertically, and means for locking said rod to hold said plate in the open and in the closed position.
6. In a safety-razor, the combination of the blade-support, the handle attached thereto, the top plate hinged to said support, a vertically-reciprocatory rod lying within the handle and hinged at its upper end to said plate, a plug rotatively seated within the lower end of the handle and threaded to the lower end of said rod, a spring engaging said rod, a pin projecting from said plug, the lower end of the handle having a slot in which said pin is adapted to travel.
7. In a safety-razor, the combination of a blade-support, a handle attached thereto, a top plate hinged to the support and adapted to clamp the plate thereon, a rod hinged to said top plate and extending downwardly through the handle, means for actuating said rod, a spring mounted upon said hinged plate and adapted to bear against the back of the blade when said plate is closed into contact therewith.
In testimony whereof I sign this specification in the presence of two witnesses.
