Smith AttorneyFidelman, Wolffe & Leitner [57] ABSTRACT An improved safety razor is disclosed having a body provided with a base portion and two opposed side portions. The base portion is provided with an operating slot and the base portion and the side portions define an operating cavity. Biasing means connect a longitudinal portion of the bridge member to the base portion of the body for normally biasing the bridge member and a pair of toothed members (which are pivoted adjacent the longitudinal portion on wing portions of the bridge member) from a blade loading open position toward the base portion of the body and for causing the second operating lugs on a pair of blade retaining members (which are pivoted adjacent the teeth on the toothed members on the wing portions) to move away from the first operating lugs on blade retaining members and toward the base portion of the body to secure the blade between the toothed members and the blade retaining members in a blade operating closed position.
A pair of crossed levers are pivotal on each otherinside the operating cavity and each has its inner end pivotally connected to a depending arm on a toothed member and its outer end extending through the operating slot in the base portion of the body. The outer ends of the crossed levers may be moved toward each other thereby causing the inner ends of the toothed members to move on the resilient body mounting lips away from the base portion of the body and the bridge member on which the inner ends of the toothed members are pivoted to move away from the base portion of the body, so that the second operating lugs on the blade retaining members move into engagement with the first operating lugs on the toothed members to cause the inner ends of such blade retaining members to move outwardly from their blade operating closed position for retaining the blade against the toothed members to their blade loading open position where the blade may be removed from the razor.
20 Claims, 7 Drawing Figures PAIENIE JUL3 I915 SHEHIBFZ INVENTOR BARTHOLOMEW A. row-I BY g d E Kit/km L im ATTORNEYS SAFETY RAZOR BACKGROUND OF THE INVENTION l-leretofore, conventional safety razors for the removal of unsightly, unwanted hair on the legs and on the underarm portions of the human body have not removed such hair swiftly, gently and safely. In addition, each blade edge is not protected from contact with the body portions. Further, it is not possible with such conventional safety razors to shave these body portions in any desired direction without cutting, gashing, nicking or pulling the human skin on these body portions being shaved. conventional safety razors are usually operable in a longitudinal direction and do not operate satisfactorily in a circular direction. Also conventional safety razors do not quickly open widely to permit the removal or replacement of the double-edged blade and to permit thorough rinsing and cleaning of the razor. Again, conventional safety razors are not tarnish proof and if carelessly cared for, do not return to their luster. Yet again, when the double-edge blade is inserted in the conventional safety razor, the blade is not automatically locked in position by the opening mechanism of the conventional razor and in perfect shaving position.
OBJECTS OF THE INVENTION It is the general object of this invention to avoid and overcome the foregoing and other difficulties of and objections to prior art practices by the provisionof an improved safety razor for the removal of unsightly and unwanted hair on the legs and underarm portions of the human body by the circular movement of the improved safety razor on such legs and underarm portions, which improved safety razor:
a. removes such hair swiftly, gently and safely,
b. protects each blade edge of the conventional double-edged blade employed therein from contact with the legs and underarm portions,
c. shaves these body portions in any desired direction without cutting, gashing, nicking or pulling the human skin on the body portions being shaved,
d. operates preferably in a circular direction rather than the conventional longitudinal direction,
e. quickly opens widely to permit the removal or replacement of the double-edged blade, and the thorough rinsing and cleaning of the safety razor,
f. is tarnish proof and retains its original luster, and
g. automatically locks the double-edged blade in perfect shaving position by release of the opening mechanism of the improved safety razor.
BRIEF SUMMARY OF THE INVENTION The aforesaid objects of this invention, and other objects which will become apparent as the description proceeds, are achieved by providing an improved razor having a body provided with a base portion and two opposed side portions. The base portion is provided with an operating slot and the base portion and the side portions define an operating cavity.
Biasing means connect a longitudinal portion of the bridge member to the base portion of the body for normally biasing the bridge member and a pair of toothed members (which are pivoted adjacent the longitudinal portion on wing portions of the bridge members) from a blade loading open position toward the base portion of the body and for causing the second operating lugs on a pair of blade retaining members (which are pivoted adjacent the teeth on the toothed members on the wing portions) to move away from the first operating lugs on blade retaining members and toward the base portion of the body to secure the blade between the toothed members and the blade retaining members in a blade operating closed position.
A pair of crossed levers are pivotal on each other inside the operating cavity and each has its inner end pivotally connected to a depending arm on a toothed member and its outer end extending through the operating slot in the base portion of the body. The outer ends of the crossed levers are movable toward each other against the action of the biasing means to move the inner ends of the crossed levers toward each other thereby causing the inner ends of the toothed members to move on the resilient body mounting lips away from the base portion of the body and the bridge member on which the inner ends of the toothed members are pivoted to move away from the base portion of the body, so that the second operating lugs on the blade retaining members move into engagement with the first operating lugs'on the toothed members to cause the inner ends of such blade retaining members to move outwardly from their blade operating closed position for retaining the blade against the toothed members to their blade loading open position where the blade may be removed from the razor.
BRIEF DESCRIPTION OF SEVERAL VIEWS OF THE DRAWINGS For a better understanding of this invention, reference should be had to the accompanying drawings, wherein like numerals of reference indicate similar parts through the several views and wherein:

FIG. 2 is a perspective view of the improved safety razor shown in FIG. 1 wherein the razor has been turned upside down and moved into the blade loading position and having the left hand end cover moved downwardly for clarity; I
FIG. 3 is a bottom view similar to a view taken from the bottom of FIG. 1 showing a double-edged blade secured between the toothed members and the blade retaining members in the blade operating closed position;
FIG. 4 is a view similar to FIG. 3 showing the blade retaining members and toothed members in the blade loading open position preparatory for the loading of a double edged blade'into the improved safety razor;
FIG. 5 is a vertical sectional view taken along the line 5-5 of FIG. 3 in the direction of the arrows;
FIG. 6 is a vertical sectional view taken along the line 6-6 of FIG. 3 in the direction of the arrows showing the improved safety razor in the blade operating closed position;
FIG. 7 is a vertical sectional view taken along the line 7-7 of FIG. 4 in the direction of the arrows showing the improved safety razor in the blade loading open position.
Although the principles of this invention are broadly applicable to safety razors, this invention is particularly adapted for use in conjunction with an improved safety razor which is operable in a generally circular direction and hence it has been so illustrated and will be so described.
DETAILED DESCRIPTION With specific reference to the form of this invention illustrated in the drawings, and referring particularly to FIGS. 1,2 an improved safety razor for the removal of unsightly and unwanted hair from the human body, particularly the legs and underarms and the like is indicated generally by the reference numeral 10.
This razor l utilizes a conventional double-edged blade 12 (FIG. 3) having opposed longitudinal outer cutting edges 14 (FIG. 3).
Said razor has a body 16 (FIGS. l-7) provided with a base portion 18 (FIGS. 1-2, 6,7) and two opposed side portions 20 (FIGS. 1-4,6and 7) projecting from the base portion 18. As shown, particularly in FIGS. 6,7 each side portion 20 tapers inwardly toward the vertical axis of the body 16 and then flares outwardly to terminate in a resilient body mounting lip 22 (FIGS. 6,7). Said body 16 is formed of stainless steel or the like and plated with a luster proof, corrosion resistant coating (not shown) such as varnish, wax or the like.
