Simpson ABSTRACT: A safety razor' in which top and bottom cooperating pressure members between which the razor blade is gripped have cooperating outwardly and downwardly extending lips extending between opposite ends. The bottom lip has a uniform radius of curvature. The top lip has a varying radius of curvature, and the top lip is tapered in its width from one end of the razor head to the other. The top lip is arcuate in cross section having different radius of curvature therealong, said radius being at a maximum value at the end of the razor top lip where the lip is narrowest, and having maximum radius of curvature at the opposite end of the razor head where the top lip is widest.

AFETY RAZOR SUMMARY OF THE INVENTION A safety razor wherein the top and bottom cooperating pressure members between which the razor blade is gripped are so constructed that the angle at which the blade edge is held as measured with respect to the horizontal has a minimum value adjacent one end of the members and increases linearly with increasing distance from the one end until it attains a maximum value adjacent the other end.
The bottom member has oppositely disposed outwardly and downwardly extending lips which extend between the two ends and has a uniform radius of curvature. The top member is similarly constructed except that the radius of curvature of the top member lip has a value adjacent said one end of the.
member and increases linearly with increasing distance until it attains a maximum value adjacent the other end.
With this structure, the blade is positioned as indicated, and a user can use different blade portions to shave different areas of the-face and obtain maximum comfort accordingly.
BRIEF DESCRIPTION OF THE DRAWINGS DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS Referring now to. FIGS. l6, atop pressure member has a flat elongated-horizontal rectangular central region 12 with I oppositely disposed lips 14 extending outward and downward between opposite ends. Each lip has a radius of curvature 'which has a minimum value adjacent one end and which increases linearly with increasing distance from the one end until it attains a maximum value at the otherend. A threaded shaft 16 extends vertically downward from the center of the bottom surface of region 12.
A bottom pressure member 18 has a flat elongated horizon tal rectangular centralsection 20 with oppositely disposed lips 22 extending outward and downward between opposite ends.
Each lip has the same uniform radius of curvature. The section 20 has a central hole-24.
In use a conventional safety razor double-edged blade 26 is disposed between members 10 and 18 with shaft 16 extending While I have described my invention with particular 7 reference to the drawings, such is not to be considered as limiting'its actual scope.
l.'In a safety razor:
a top member having a flat horizontal center section with at least one linear side, said at least one side having a lip extending outward and downward between opposite ends, said lipliaving an outer edge disposed at a distance from said linear side which increases from a minimum value adjacent one end to a maximum value adjacent the other a lf om member having a like center section with at least one lip extending outward and downward beyond said top member lip outer edge between opposite ends and underlying said top-member lip, said bottom member lip having a guard portion disposed parallel to said at least one linear side; and
means for'gripping a razor blade between said top and bottom members.
2 A razor as set forthin claim 1 wherein the distance of said outer edge from said at least one linear side increases linearly
