To all whom it may concern:
Be it known that I, Alonzo A. Warner, a citizen of the United States, residing at New Britain, county of Hartford, Connecticut, have invented certain new and useful Improvements in Safety-Razors, of which the following is a full, clear, and exact description.
My invention relates to improvements in shaving appliances, and particularly to “safety razors,” so called.
The object of the invention is to provide simple and effective means whereby the cutting edge of the blade or blades may be adjusted relatively to the guard portion. The construction comprises but few parts, all of which are easily assembled for use or separated for cleaning.
In the drawings,
As shown in
In the preferred form of construction the abutment
From the foregoing it will be seen that to adjust the blades it is merely necessary to let up slightly on the thumb-nut
What I claim is—
1. In a safety-razor, a guard or backing member, guard-tongues at opposite edges thereof, two independent blades providing cutting edges adjacent to the guard members at each edge of the backing member, means for moving simultaneously said blades toward or away from each other for causing said cutting edges to project more or less, as desired, relatively to the guard-edges, said means consisting of an adjusting member positioned between the guard member and clamping-plate and provided with a series of pins engaging in slots in each of said blades.
2. In a safety-razor, a backing or guard member, an abutment thereon and extending transversely thereof, a blade notched to engage said abutment and laterally movable relatively to said backing member, an adjusting device longitudinally movable relatively to said backing member, a guide-pin carried by said adjusting device, a cam-groove in said blade into which said guide-pin projects, all arranged whereby when the adjusting member is moved longitudinally the blade will be moved laterally to expose more or less of its cutting edge, and means for clamping said parts rigidly in any desired position of adjustment.
3. In a safety-razor, a handle having a backing portion with guard-teeth arranged along opposite edges and disposed on opposite sides of the longitudinal axis of the handle, and a longitudinal groove, an adjusting member located in said groove, and means for clamping a blade to the backing portion.
