To all whom it may concern:
Be it known that I, Phillip H. Unsinger, a citizen of the United States, and a resident of Fremont, in the county of Sandusky and State of Ohio, have invented a certain new and useful Safety-Razor; and I do hereby 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.
My invention relates to safety-razors, and has for its object the provision of a razor of this class which is simple and inexpensive in its construction and manufacture, composed of a minimum number of parts, and capable of having its blade clamping parts easily and quickly engaged or disengaged to facilitate the insertion therein or removal of a blade therefrom.
The invention is fully described in the following specification, and a preferred embodiment thereof is illustrated in the accompanying drawing, in which,—
Referring to the drawings,
The clamping plate or part
With this form of safety-razor it is exceedingly simple to remove the blade for cleaning or other purpose and to replace it er substitute another therefor, as a withdrawal of the clamping plate
I wish it understood that my invention is not limited to any specific construction or arrangement of the parts except in so far as such limitations are specified in the claim.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is,—
A safety-razor comprising a plain holder-plate the forward edge of which is turned laterally to form a guard and provided with an elongated opening, a handle projecting from said holder-plate, a blade, a blade clamping-plate having ears projecting laterally in the same direction and inwardly from its ends to slidingly engage under the ends of the holder-plate to clamp the clamping-plate and interposed blade thereto, said clamping-plate having a part angling from its rear edge in the same direction as said ears to coact with the holder-plate to limit the movement of the clamping-plate thereon and having spurs projecting from its forward edge over the blade corners and inwardly in advance thereof, said spurs acting to with draw the blade from the holder when the clamping plate is withdrawn therefrom and the clamping-plate serving to hold a blade preparatory to clamping the same to the holder, substantially as described.
In testimony whereof, I have hereunto signed my name to this specification in the presence of two subscribing witnesses.
Phillip H. Unsinger.
