Lubricant-applying safety razor

Claim 2

A safety razor including a handle, a blade-supporting head carried by one end of said handle, cutting blade means supported in said blade-supporting head, a lubricant member supported by said blade-supporting head in a position in advance of said cutting blade means when said safety razor is moved along the skin of the user in a shaving motion, said lubricant member comprising an elongate cylindrical roll including a peripheral surface for engaging the skin of the user in advance of said cutting blade means and being provided to apply a lubricous film to the skin in advance of said cutting blade means for reducing the coefficient of friction between the wet skin surface and the lubricous film, said peripheral surface having a length extending throughout substantially the width of said cutting blade means and providing a guide surface initially positioning the skin surface of the user in a particular angular relationship with said cutting blade means, said peripheral surface of said lubricant member being frictionally worn away and lowered with continued use of said safety razor so that the blade tangent angle between said cutting blade means and said peripheral surface of said lubricant member is gradually increased within a limited angular range with use of said razor, shaft means extending through the center of said cylindrical lubricant roll, and stop means associated with said shaft means for normally maintaining said cylindrical lubricant roll and said shaft means in a non-rotating position.

Claim 3

A safety razor according to claim 1 wherein said stop means comprises detent means carried by said blade-supporting head for engagement with said shaft means and normally preventing rotation of said shaft means and said lubricant cylinder carried thereby.

Claim 4

A safety razor according to claim 2 wherein said shaft means includes three equally spaced and outwardly extending elongate ribs extending between opposite inner side portions of said blade-supporting head, said lubricant cylinder being molded around and between said elongate ribs of said shaft means to prevent rotation of said lubricant cylinder relative to said shaft means.

Claim 5

A safety razor according to claim 3 wherein said detent means is positioned on the inner surface of one side of said blade-supporting head and extends between the ends of a pair of adjacent of said ribs of said shaft means for resiliently maintaining said shaft means in a normally non-rotating condition.

Claim 6

A safety razor according to claim 4 wherein said shaft means extends outwardly beyond the outer surface of one side of said blade-supporting head, and including means carried by the portion of said shaft means extending beyond the outer surface of said one side of said blade-supporting head for manually rotating said shaft means over the resilient biasing of said detent means for presenting a new peripheral surface of said lubricant cylinder to be engaged by the skin of the user.

Claim 7

A safety razor including a blade-supporting head, upper and lower successive cutting blades supported in said blade-supporting head with their cutting edges in spaced parallel relationship, a lubricant member supported by said blade-supporting head in a position in advance of said lower cutting blade when said safety razor is moved along the skin of the user in a shaving motion, said lubricant member including a peripheral surface for engaging the skin of the user in advance of said lower cutting blade and being provided to apply a lubricous film to the skin in advance of said lower blade for reducing the coefficient of friction between the wet skin surface and the lubricous film, said peripheral surface provides a guide surface initially extending above a plane tangent with said cutting edge of said lower blade and said guide surface so that the skin is initially engaged by only the cutting edge of said upper cutting blade, said peripheral surface of said lubricant member being frictionally worn away and lowered with continued use of said safety razor so that the skin is engaged by the cutting edges of both of said cutting blades with a predetermined lowering of said peripheral surface of said lubricant member, and so that the skin is engaged by only the cutting edge of said lower cutting blade with an additional predetermined lowering of said peripheral surface of said lubricating member whereby the changing position of the peripheral surface of said lubricant member serves to continuously change the angular position of the skin of the user in relation to the upper and lower cutting blades as lubricant is removed from said peripheral surface of said lubricant member.

Claim 8

A safety razor including a blade-supporting head, upper and lower successive cutting blades supported in said blade-supporting head with their cutting edges in spaced parallel relationship, a lubricant member supported by said blade-supporting head in a position in advance of said lower cutting blade when said safety razor is moved along the skin of the user in a shaving motion, said lubricant member including a peripheral surface for engaging the skin of the user in advance of said lower cutting blade and being provided to apply a lubricous film to the skin in advance of said lower blade for reducing the coefficient of friction between the wet skin surface and the lubricous film, said peripheral surface provides a guide surface initially extending above a plane tangent with said cutting edge of said lower blade and said guide surface so that the skin is initially engaged by only the cutting edge of said upper cutting blade, said peripheral surface of said lubricant member being frictionally worn away and lowered with continued use of said safety razor so that the skin is engaged by the cutting edges of both of said cutting blades with a predetermined lowering of said peripheral surface of said lubricant member, and so that the skin is engaged by only the cutting edge of said lower cutting blade with an additional predetermined lowering of said peripheral surface of said lubricating member whereby the changing position of the peripheral surface of said lubricant member serves to continuously change the angular position of the skin of the user in relation to the upper and lower cutting blades as lubricant is removed from said peripheral surface of said lubricant member.

Claim 9

A safety razor according to claim 6 wherein said lubricant member comprises a solid bar formed of cosmetic grade ingredients having a skin engaging surface adapted to deposit a lubricous film onto the skin surface from said skin engaging surface.

Claim 10

A safety razor according to claim 7 wherein said solid bar is round in cross section and is of substantially the same length as the width of said cutting blades.
