This invention relates to safety razors, and more particularly to a safety razor of the type wherein the blade is reciprocated longitudinally during the cutting operation.
Heretofore, in safety razors of the type herein disclosed, the blade has been mounted on a carriage and the latter reciprocated by various means. Such a structure is objectionable in that the weight of the razor, due to the carriage is increased, and the reciprocating action of the blade is not positive.
It is an object of this invention to provide a safety razor in which the blade is directly reciprocated, no carriage for the blade being necessary.
A further object is the provision of a reciprocating device in such a razor, wherein the number of actuating elements is reduced to a minimum, thus greatly simplifying the action of the razor and reducing the cost of manufacture.
These and other objects are attained by the novel construction, combination and arrangement of parts hereinafter described and shown in the accompanying drawing, constituting a material part of this disclosure and in which:
Referring to the drawing, the safety razor is shown to include a handle
The plate
The retaining plate
In operation, the blade
In
The blade is provided with an aperture
It will be seen that the blade, in addition to the usual cutting action, has a transverse cutting action, which insures a positive cutting of the hairs. This feature is especially desirable for tough beards in which the usual blade has a tendency to slide over the hairs. With the razor herein disclosed, the transverse cutting action prevents the sliding of the blade over the hairs, and insures a smooth and satisfactory shave. The foregoing disclosure is to be regarded as descriptive and illustrative only, and not as restrictive or limitative of the invention, of which obviously an embodiment may be constructed including modifications without departing from the general scope herein indicated and denoted in the appended claims.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is :
1. In a safety razor, a handle, a razor blade support attached to the handle, a plate for retaining the blade on the support, a saddle slidably mounted on said plate, a pin projecting from the saddle, and cam means rotatably mounted on the plate for cooperating with the pin to reciprocate the saddle.
2. In a safety razor, a handle, a razor blade support fixed to the handle, lugs projecting upwardly from said support to position a razor blade thereon, a plate for retaining the blade on the support, a saddle slidably mounted on the plate, a pin fixed to the saddle, said pin having a head adapted to pass through a central aperture in a blade carried by the support, and cam means carried by the plate for cooperating with the pin to reciprocate the saddle.
3. In a safety razor, a tubular handle, a razor blade support attached to the handle, said support having an aperture directly above the tubular handle, a plate for retaining a blade on the support, a saddle slidably mounted on the plate, a pin fixed to the saddle, said pin having a head passing through the aperture in the support, and cam means carried by the plate for cooperating with the pin to reciprocate the saddle.
4. In a safety razor, a handle, a razor blade support attached to the handle, means on the support for positioning a razor blade thereon, a plate for retaining a blade on the support, a pin slidably mounted on the plate, and cam means carried by the plate and cooperating with the pin to reciprocate the latter.
5. In a safety razor, a handle, a razor blade support attached to the handle, a plate for retaining a blade on the support, a pin slidably mounted on the plate, and cam means carried by the plate and cooperating with the pin to reciprocate the latter.
6. In a safety razor, a handle, a razor blade support attached to the handle, a plate for retaining a blade on the support, a pin slidably mounted on the plate, and a roller carried by the plate, said roller having a cam slot cooperating with the pin to reciprocate the latter.
7. In a safety razor, a handle, a razor blade support fixed to the handle, means on the support to position a razor blade, a plate for retaining a blade on the support, a saddle slidably mounted on the plate, a pin fixed to the saddle, said pin having a head adapted to pass through a central aperture in a blade carried by the support, and means carried by the plate for cooperating with the pin to reciprocate the saddle.
8. In a safety razor, a handle, a razor blade support attached, to the handle, a razor blade having a central aperture, means to position the blade on the support, a plate for retaining the blade on the support, a saddle slidably mounted on the plate, a pin fixed to the saddle and having a head passing through the aperture in the blade, and means carried by the plate cooperating with the pin to reciprocate the saddle.
9. In a safety razor, a handle, a razor blade support attached to the handle, a razor blade having a pair of slots, a plate for retaining the blade on the support, a pin slidably mounted on the plate, said pin engaging the razor blade, cam means carried by the plate and cooperating with the pin to reciprocate the blade, and a pair of projections on the support cooperating with the slots to guide the blade.
In testimony whereof I affix my signature.
John L. King.
