To all whom it may concern:
Be it known that I, Clifford E. Dunn, a citizen of the United States, residing in the city of New York, borough of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Safety-Razors, of which the following is a full, clear, and exact specification.
This invention relates to safety razors, such as are adapted particularly for use in connection with flexible blades, although they can be used with other kinds of blades if desired.
The objects of the invention are to improve and simplify the construction of such devices; furthermore, to increase their efficiency in use, and to decrease the expense attending their manufacture.
With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter set forth, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of the following claims without departing from the spirit of the invention.
In the accompanying drawings forming part of this specification,
The reference numeral
A cam construction is illustrated for adjustably forcing the clamping members
The modified construction shown in
The improved razor of the present invention is strong, simple, durable, and inexpensive in construction, as well as thoroughly efficient in operation.
What is claimed is:
1. A safety razor having a pair of blade clamping members, a rack connected with one of said members, and a pivotally-mounted locking device connected with the other of said members and having its free end located in position to engage said rack for locking said members together.
2. A safety razor comprising a guard having a central opening therein, a handle having a yoke-shaped portion connected with said guard and provided with a curved rack, a cap having a pair of lugs and a locking device pivotally mounted between said lugs having a cam portion, said locking device being adapted to extend through the opening in said guard and to be engaged with its free end with said curved rack.
3. A safety razor having a pair of clamping members adapted to flex a thin razor blade, one of said members having an opening therein, a pivotal locking device connected with the other of the said members extending through said opening, and a rack fast with one of said members and located in position relatively to the free end of said pivotal locking device so as to be engaged thereby.
In testimony whereof, I have hereunto set my hand in the presence of two subscribing witnesses.
Clifford E. Dunn.
