To all whom it may concern:
Be it known that I, Thomas C. Durham, a citizen of the United States, residing at New York, in the county and State of New York, have invented a new and useful Razor, of which the following is a specification.
This invention relates to an improvement in razors and one of the objects thereof is to provide a device in which a thin, replaceable blade is used and which may be used in the same manner as one of the usual type.
Another object is to provide a device of this character in which devices are employed for locking the blade in position, these devices being located beyond the ends of the blade.
With these and other objects in view, the invention consists in certain constructions and combinations which will be hereinafter fully described and then specifically pointed out in the claims hereunto appended.
In the drawings which form a part of this specification and in which like characters of reference indicate the same parts,
In the device selected to illustrate the invention there is provided a thin blade
Means are provided for locking the blade in position, this means being carried by the clamp and located beyond the ends of the blade, engaging the support and having a sliding movement thereon to lock the blade in position. In the best constructions and as shown, the clamp
It will be readily understood that the blade is positioned by bringing the studs
Changes and variations may be made in the structure by which the invention is carried into effect. The invention, therefore, is not to be restricted to the precise details of the structure shown and described.
What is claimed is:
1. In a razor, the combination with a support, of a clamp, a detachable blade, means for positioning the blade between the support and clamp, and means carried by the clamp beyond the ends of the blade engaging the support and having a limited sliding movement thereon to lock the blade in position, substantially as described.
2. In a razor, the combination with a support having a plurality of slots, of a clamp, a detachable blade, means for positioning the blade between the support and clamp, and a plurality of headed studs carried by the clamp beyond the ends of the blade and having a limited sliding movement in the slots of the support to lock the blade in position, substantially as described.
3. In a razor, the combination with a support having two countersunk slots, of a clamp, a detachable blade having two perforations, studs carried by the clamp and engaging the perforations to position the blade between the support and clamp, and two headed studs carried by the clamp beyond the ends of the blade and engaging the slots in the support to lock the blade in position, substantially as described.
In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
Thos. C. Durham.
