Abstract: A razor blade assembly including a body member, a guard member mounted on the body member for movement thereon, a blade member mounted on the body member for movement thereon, the guard member and the blade member being independently movable in response to forces encountered during a shaving operation, spring finger biasing members integral with the body member and exercising a bias against the guard member and the blade member, a cap portion fixed to the body member, and connector structure integral with the body member for connection of the blade assembly to a razor handle.

Abstract: Shaving units as well as methods and apparatus for producing such units by using laser energy to weld a narrow elongated razor blade strip to a support member. In one form of the invention, a perforated welding mask made from a metal having high reflectance to the laser energy is employed to define the spacing of the welds joining the two members.

Abstract: A razor blade unit has a blade member, a guard member located forward of the exposed edge of the blade member, and integral adjusting mechanism operable independently of the razor handle for changing the positioning of the blade and guard members relative to one another to vary the shaving geometry.

Abstract: A razor blade assembly including a body member, a guard member mounted on the body member for movement thereon, a blade member mounted on the body member for movement thereon, the guard member and the blade member being independently moveable in response to forces encountered during a shaving operation, spring finger biasing members integral with the body member and exercising a bias against the guard member and the blade member, a cap portion fixed to the body member, and connector structure integral with the body member for connection of the blade assembly to a razor handle.

Abstract: A razor handle for a razor blade assembly adapted to be movably mounted on the handle, the razor handle having opposed and aligned journal means disposed on arm portions, the arm portions being movable toward and away from each other reciprocally and axially of the journal means to permit the journal means to engage and disengage the razor blade assembly.

Abstract: A razor blade assembly is provided with blade means mounted in a housing adapted to be connected to arms of a razor handle. The housing is provided with journal bearings for receiving journals on the arms of the razor handle. The housing is further provided with cam means at either end thereof. The journal bearing means form a pivot axis for pivotal movement of the razor blade assembly thereabout and the housing cam means is in engagement with biasing means on each arm of the handle when the blade assembly is mounted on the razor handle.

Abstract: A shaving system including a razor handle and a replaceable blade assembly, the handle having first and second arms with first and second journals thereon, the arms being movable away from each other in such manner as to cause the journals to move away from each other along a common axis, a spring for biasing the arms toward each other, and a cam disposed on each of the arms, and a blade assembly including a housing having first and second journal bearings for receiving the first and second journals for pivotal mounting of the blade assembly on the handle, and cam surfaces for complemental engagement with the handle cams, the cam surfaces and handle cams cooperating to urge the blade assembly to a neutral position.

Abstract: A razor handle for a razor blade assembly adapted to be pivotally mounted on the handle, the razor handle having first and second arm portions with journal means disposed thereon for pivotal connection to journal bearing means on the blade assembly, each arm portion having cam means thereon engageable with complementary cam means on the blade assembly, the cam means cooperating to urge the pivotally mounted blade assembly toward a neutral position.

Abstract: A scraper assembly comprising a housing having a chamber therein adapted to receive and releasably retain blade units, the housing having a head portion adapted to receive and retain a first of the blade units, and a cover member adapted to cover the first blade retained by the head portion, the cover member being releasably retained by engagement with the head portion, the cover member being further adapted to cover portions of the housing remote from the head portion, the cover member being releasably retained by engagement with a second portion of the housing, whereby the cover member may be selectively positioned to cover the first blade unit and may be removed therefrom and positioned on the housing at an end remote from the first blade unit to expose the first blade unit for scraping operations, and a lock means, comprising an integral portion of the housing, for locking the first blade unit in the head portion.

Abstract: A scraper assembly comprising a housing having a head portion adapted to receive and retain a blade unit, and a cover member adapted to cover the blade retained by the head portion, the cover member being releasably retained by engagement with the head portion and completely separable therefrom, the cover member being further adapted to cover portions of the housing remote from the head portion, the cover member being releasably retained by engagement with a second portion of the housing and completely separable therefrom, whereby the cover member may be selectively positioned to cover the blade unit and may be removed therefrom and positioned on the housing at an end remote from the blade unit to expose the blade unit for scraping operations, and may be completely removed from the remainder of said assembly.
