My Invention pertains to a safety razor in which the blade is of the type known as a straight razor, the blade including a thick heel or back portion and tapering therefrom towards the cutting edge, the faces of the blade between the heel and the cutting edge being of hollow ground contour. The blade is associated with a safety guard which will be presently described. The object of my invention is to provide a razor in which the blade is associated with a guard and a handle, the blade with the guard being adapted to be mounted either endwise or crosswise upon said handle, as desired. A further object of my invention is to provide a razor including a blade to be used in the manner of a straight razor but with a guard thereon, which guard may be frictionally held upon the blade without any special additional means.
Another object of my invention is to provide a razor in which the relative position of the cutting edge of the blade with respect to a part of the guard extending along said cutting edge may be conveniently regulated by a turn of the handle. A further object of my invention is to provide a razor blade which, when mounted on the handle endwise, may be honed or stropped in the manner of a straight razor.
I shall now describe my invention with reference to the accompanying drawings, in which:
Similar numerals refer to similar parts throughout the several views.
The razor comprises three separate elements: the blade, best shown in
The blade, generally indicated by numeral
The guard, generally indicated by numeral
When the razor is to be used in the manner of a conventional straight razor, the threaded end
When the blade is to be disposed transversely to the handle, the guard is first slipped over the blade in such a manner that the opening
For stropping the razor the blade is simply affixed endwise to the handle, as shown in
It will be understood that some changes may be made in the structure of my razor without departing from the inventive principle disclosed herein.
What I, therefore, wish to claim is as follows:
A safety razor comprising a blade having a thick heel portion defined by a flat back, a flat top, and a flat under side, said blade tapering from the heel portion to a cutting edge, the blade being provided, midway its length and transversely thereto, with a threaded opening, a guard frictionally retained over the heel portion and including an apron on the under side of the blade, the apron extending in the direction of the edge of the blade and being in a yieldable progressively expanding spacing to said blade, the guard being provided with an opening for alinement with the threaded opening in the blade and including an outwardly extending lip along the edge of the blade and in a normally spaced relation thereto, and a handle having a threaded end for engagement with the threaded opening in the blade and a shoulder below its threaded end for abutment with the apron at a point where the apron is spaced from the blade to adjust the spacing between the lip of the apron and the cutting edge of the blade.
