I, James Clarence Friel, a citizen of the United States of America, of Great Northern Hotel, 118, West 57th Street, New York, United States of America, do hereby declare the nature of this invention and in what manner the same is to be performed, to -be particularly described and ascertained in and by the following statement:—
This invention relates to safety razors of the type which carries a hone in operative proximity to the blade, normally retracted from the shaving edge but arcuately reciprocable in surface contact with said edge when the razor is shaken for sharpening the blade.
One of the objects of the invention is to provide a razor of the type described, in which the forward portion of the blade, positioned at proper honing angle rests against the hone, just back of the bevel of the shaving edge when the parts are in shaving position, with means bearing resiliently against said blade close to the region at which the blade rests against the hone, for bringing the blade into continuous contact with the hone from end to end so that when the hone slides out beneath the edge of the blade, the latter will make continuous contact with the hone. This provision is necessitated through the fact that more often than not, razor blades are not truly planiform but have a “wind,” so that only a portion of a longitudinal element of a blade will touch a straight edge.
A further object of the invention is to provide a razor equally adapted for use with a blade either of the conventional single edge or double edge form and having blade positioning means for either type of blade, coacting therewith to prevent forward, backward, or lateral displacement of the blade, but permitting free upward movement of the rearward portion of the blade responsive to depression of any longitudinal portion of the forward part by the said resilient means, thereby avoiding distortion of the blade, which distortion would create uneven pressure between the edge of the blade and the hone.
A further object of the invention is the provision of means for adjusting the pivot about which the hone swings, so as to compensate for wear which would cause the hone to fail to make contact with the blade.
With the above and other objects, the invention comprises the several combinations set out in the claims.
Such combinations are embodied in a preferred and practical embodiment thereof which will now be described :—
In the drawings, which accompany and form a part of the following specification, and throughout the several figures of which the same characters of reference have been employed to designate identical parts :—
Referring now in detail to the several figures, the numeral
The head
The hone
The length of the lever
The subject razor is devised to take either a single edge blade, such as is shown at
The subject invention provides means for holding either of these blades at the proper shaving and honing angle and in such a manner that they will not become displaced in a forward, backward or sidewise direction. This is an important feature when it is considered that the razor is honed by shaking it back and forth so that in the absence of suitable restraints the blade would readily become displaced.
Now referring to the head construction, as shown in
The end flanges
The inclination of the bottoms
It will be observed in
Referring once again to
The fact that the carrier plate
In operation, when the razor is grasped for shaving, the thumb is placed over the slot
Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is:—
1. Safety razor comprising a head including a base plate having upstanding side flanges, a stem secured to said base plate, a lever pivoted relative to said stem, a hone at the upper end of said lever reciprocable in a forward and backward direction between said flanges close to said base plate when said razor is shaken, said side flanges being formed with blade positioning seats inclined downwardly and forwardly and terminating rearwardly of the forward portion of said blade permitting the forward portion to rest against said hone, a resiliently actuated cover clamp engageable with the forward portion solely of the blade for bringing it into continuous longitudinal contact with said hone from end to end.
2. Safety razor as claimed in claim 1, said blade positioning seats being constructed to permit free rise of any longitudinal part of the rear of said razor responsive to the depression of any longitudinal part of the forward portion of said razor by said cover clamp.
3. Safety razor comprising a head including a base plate having upstanding side flanges, a stem secured to said base plate, a lever pivoted relative to said stem, a hone member at the upper end of said lever including a hone and a shaving guard forwardly of said hone, said hone member being reciprocable in a forward and backward direction between said flanges close to said base plate when said razor is shaken, said side flanges being formed with blade positioning seats inclined downwardly and forwardly and terminating rearwardly of the forward portion of the blade permitting the forward portion to, rest against said hone, a resiliently actuated cover clamp engageable with the forward portion solely of the blade for bringing it into continuous longitudinal contact with the hone from end to end, said hone member having a retracted position in which the hone is rearward of the shaving edge of the blade and the guard is in operative position relative to said edge.
4. Safety razor according to any of the preceding claims adapted for alternative use with a conventional double edge or single edge blade.
5. Safey
6. Safety razor according to any of the preceding claims including a head and a hollow stem secured to said head, means for supporting a blade in shaving and honing position in said head, a longitudinally adjustable cross head in said stem, a lever pivoted to said cross head swingable through a slot in said stem, a hone at the free end of said lever reciprocable when said razor is shaken into honing engagement with said blade, and means accessible at the free end of said stem for moving said cross head to adjust the contact of said hone wth
7. Safety razor according to any of the preceding claims, comprising a head including a base plate having upstanding side flanges, a stem secured to said base plate, a lever pivoted relative to said stem, a hone at the free end of said lever reciprocable in a forward and backward direction between said flanges close to said base plate when said razor is shaken, said side flanges being formed with blade positioning seats, a pair shaped to receive and position a conventional double edge blade and a pair shaped to receive and position a conventional single edge blade, said recesses being inclined downwardly and forwardly and terminating rearwardly of the forward portion of the blade permitting the forward portion of the blade to rest against said hone, the respective pairs of seats being so relatively placed in a front to back direction as to bring the forward edge positions of both blades into coincidence, a resiliently actuated cover clamp engageable with the forward portion solely of either blade for bringing it into continuous longitudinal contact with said hone from end to end.
8. Safety razor according to any of the preceding claims, comprising a head having side flanges, each side flange being formed with an inner and outer recess, the outer recesses of both flanges being adapted to receive the extended intermediate end portions of a two-edge blade, the inner recesses of both flanges being adapted to receive the thick portion of a single edge blade, a stem secured to said head, a lever pivoted relative to said stem, a hone at the upper end of said lever reciprocable in a forward and backward direction between said flanges below said recesses when said razor is shaken, both the inner and outer recesses having bottom blade supporting walls and being of such relative depth as to position the forward portion of the respective blades in substantially the same plane, said outer recesses having front and back walls forming stops limiting the forward and backward movement of the double edge blade, said inner recesses having front walls adapted to engage the adjacent front edge of the thick back of the single edge blade to limit forward movement of said blade, said inner recesses having rear walls extending inwardly and above the plane of the bottom walls of the outer recesses, functioning as back stops for the single edge blade and as lateral stops engageable with the ends of the rear relatively short portion of the double edge blade, said recesses terminating rearwardly of the forward portion of either blade, permitting the forward portion to rest against said hone, a resiliently actuated cover clamp engageable with the forward portion solely of either blade for bringing it into continuous contact with said hone from end to end, said recesses being formed to permit free rise of any longitudinal part of the rear of said razor responsive to the depression of any longitudinal part of the forward portion of said razor by said cover clamp.
