To all whom it may concern:
Be it known that I, Ernest N. Humphrey, a citizen of the United States, residing at New Britain, Hartford county, State of Connecticut, have invented certain new and useful Improvements in Safety-Razors, of which the following is a full, clear, and exact description.
This invention relates to so-called “safety razors,” and is designed to provide a simple and efficient structure of this character. An efficient blade-clamping means is provided which will afford ready access to the blade and razor parts when it is desired to remove the blade or cleanse the razor.
It is my aim to provide an effective structure of this character which readily lends itself to afford substantial economies in manufacture.
To this end my invention consists in the relative arrangement and combination of parts more fully described in the following specification, taken in connection with the accompanying drawings forming part thereof and illustrating preferable embodiments of the invention.
In these drawings:
Referring to the drawings by numerals,
It will hardly be necessary to describe the operation of the razor in detail, as the locking function of the clamping plate
The provision of wedging means affords a very efficient frictional clamp which will maintain the razor blade in adjusted position during use. By providing a pivot point for the clamping arm which is offset from the plane of the supporting plate, the clamping arm may overlap and engage substantially the entire length of the razor blade and in addition it may be swung absolutely clear of the razor blade to facilitate removal and replacement thereof as well as to permit perfect cleansing of the parts.
While I have herein illustrated and described a specific embodiment of my invention, it should be understood that the same may be altered in detail and relative arrangement of parts within the spirit of the invention and the scope of the appended claim.
What I claim, therefore, and desire to secure by Letters Patent is:
In a safety razor, a handle, a blade-supporting plate rigidly connected thereto at an angle and having a guard at its forward edge and stop shoulders adjacent said edge for a razor blade, said plate also having a longitudinally extending offset adjacent its rear edge and having integral lugs extending upwardly from its sides intermediate its forward and rear edges and overlying the upper face of said plate, the under faces of said lugs being formed with a bevel, a clamping arm pivoted at one end and adjacent its rear edge to said longitudinal offset and arranged to extend longitudinally of said plate for substantially its entire length and in a plane parallel therewith, said arm being arranged to swing toward and from the rear edge of said plate and being constructed to engage with its upper face the beveled under faces of said lugs whereby the under face of said arm may be wedged in frictional clamping engagement with the upper face of a razor blade seated over said supporting plate.
Ernest N. Humphrey.
