International Classification:

B08B 304

US Classification:

134 26

Abstract:

A machine for removing oil, dirt and grinding debris from a metal surface comprises a plurality of wash, rinse and dry stations separated to prevent contamination carryover from one station to the next. Razor blades in stacks are passed through the stations, the stacked blades being mounted on rods supported by a fixture and the nozzles or jets within the machine being so oriented as to cause a riffling of the blades due to water or air pressure. A purified water rinse and preferably an aqueous cleaning solution are employed in the machine and are circulated through the stations by a flow system which provides efficient and economical usage of the cleaning solution and rinse materials.

Abstract:

An oscillating wet shave razor with a battery powered motor rotating an eccentric element within the head portion of the razor handle to generate an oscillating vibration signal which is transmitted to the razor blade cartridge to desensitize the facial nerves from the discomforts of shaving. The vibration which is transmitted to the cartridge is partially damped in the direction perpendicular to the surface of the cartridge that engages the user's face so that the blades mounted in the cartridge tend not to chop at the whiskers of the user's beard during shaving.
