Patent number: 4819330Abstract: An electric shaver having a handle, and a shaver head having a cutting blade, which is movably carried on the handle. A battery and electric motor are mounted in the handle. A drive member on the motor provides reciprocating movement to a pivotally mounted weight member in the shaver head. The arrangement is such that the weight member reciprocates back and forth at a high rate of speed and imparts reciprocatory, simple harmonic motion to the cutting blade carried by the shaver head. The cutting action is characterized by minimal movement in any direction except essentially linearly, substantially parallel to the blade. Improved shearing action of the hairs is realized, together with minimum tendency for pulling or tearing of the skin. Undesirable irritation, and the development of "nicks" are thereby significantly reduced.Type: GrantFiled: October 5, 1987Date of Patent: April 11, 1989Inventors: Lawrence E. Fenn, Leo Chateauneuf

Patent number: 4813136Abstract: A dry shaver comprises a basic unit housing together with a shaver head having a longitudinally extending upper blade and a reciprocatorily drivable longitudinally extending lower blade acting in conjunction therewith. A swinging bridge is secured in the basic unit housing and has a reciprocatory output part for driving the lower blade and a stationary base part provided with an aperture. An electric motor having an essentially-cylindrical housing has one end of the motor housing connected to the stationary base part of the swinging bridge, the drive shaft of the motor extending through the aperture in the base part into the output part of the swinging bridge. An eccentric on the drive shaft drives the output part. A frame-like motor support has a transverse U-shape, one end of such support being connected to the stationary base part of the swinging bridge.Type: GrantFiled: April 29, 1988Date of Patent: March 21, 1989Assignee: U.S. Philips CorporationInventors: Herbert Piber, Gunther Schmid, Johann Schuhfleck

Patent number: 4744144Abstract: A hand held, oscillating razor for wet shaving which comprises an internally operated eccentric for forcibly, rapidly vibrating the cutting blades. Preferably the razor comprises an elongated, generally tubular housing adapted to receive a carriage which mechanically secures a rotatable eccentric, a motor for rotating the eccentric, and an associated angularly tilted battery which powers the motor. A receptacle integrally associated with the neck of the housing is adapted to removably receive a standard blade cartridge for shaving. The razor exhibits a characteristic resonant frequency, and its center of mass lies apart from its central axis, so that the razor characteristically displays a dynamic couple in operation. The motor rotates within a speed range of between 1.414 and two times the natural resonant frequency of the razor so as effectuate as comfortable a shave as possible. Within this range razor shaving characteristics are substantially unaffected by the mode or manner in which the unit is held.Type: GrantFiled: April 2, 1986Date of Patent: May 17, 1988Assignee: Wellington Investments, Inc.Inventors: Charles M. Lowery, Sr., Jimmie George

Patent number: 4642892Abstract: Herein disclosed is a T-shaped razor comprising a holder, and a head attached to the holder and having at least one blade. The head is supported such that it can move in directions which are inclined generally in the longitudinal direction of the holder with respect to a plane longitudinal in the extending direction of the edge of the blade. Further comprised is drive means which is disposed in the holder for reciprocating the head obliquely.Type: GrantFiled: December 5, 1984Date of Patent: February 17, 1987Assignee: Feather Safety Razor Co., Ltd.Inventor: Minoru Ishida

Patent number: 4630933Abstract: A clock and shaver combination unit comprises a casing provided with an electric clock and a battery source therefor and a self-contained battery powered electric shaver removably received in a compartment in the casing. The shaver is in use to be removed from the casing and utilized separately from the clock, while it can be held in the clock casing when the shaver is not in use. This permits the user to always look at the time while his is shaving, yet enabling the user to carry the shaver together with the clock as one integral unit.Type: GrantFiled: March 3, 1986Date of Patent: December 23, 1986Assignee: Matsushita Electric Works, Ltd.Inventor: Sadashige Horii

Patent number: 4604801Abstract: Dry shaver with an auxiliary frame displaceably insertable in the direction of the lower cutter, said frame being retained via spring-tensioned locking means in the end cheeks of a shaver housing or of a cutting head frame, and unlocked and removed in the removal direction by unlocking buttons, which act on the up ramps provided on the locking means.Type: GrantFiled: April 17, 1985Date of Patent: August 12, 1986Assignee: Braun AktiengesellschaftInventors: Roland Ullmann, Hans E. Heintke

Patent number: 4486951Abstract: Shaving apparatus including reciprocating, rotary and endless belt blades having at least one cutting edge. The belt blade is trained around three spaced apart rollers having their longitudinal axes parallel. The blade and rollers are enclosed in a housing with the length of the blade between two of the rollers creating a flat surface cutting edge to effect the cutting operation. One of the rollers is driven thereby causing the endless belt blade to rotate continuously in a direction parallel to the cutting edge thereof. A cover fits over the cutting blade extending between two of the rollers and is provided with an opening through which the cutting edge of the blade protrudes. A protective comblike shield covers the opening in the head. A second embodiment of the cutting blade is a circular disk with its circumference sharpened to form a cutting edge.Type: GrantFiled: September 3, 1982Date of Patent: December 11, 1984Inventor: Martin N. Leibowitz

Patent number: 4420702Abstract: There is provided an apparatus such as a dry shaver comprising a housing formed by two opposing housing shells. An electric motor is mounted on at least one support extending from one housing shell. Adjacent the support a resilient hook is formed integrally with, and projects from, such one housing shell in order to secure the motor to the shell, the resilient hook engaging an edge portion of the motor and urging the motor against the support. A projection extends inwardly from the other housing shell to engage the resilient hook and thereby constitute a stop for it and position the hook relative to the motor.Type: GrantFiled: July 12, 1982Date of Patent: December 13, 1983Assignee: U.S. Philips CorporationInventor: Ingomar Mixner

Patent number: 4381604Abstract: A razor blade holder includes a base plate and a top jaw. A cylindrical sleeve is attached to the base plate by two loops on the back of the base plate going under the cylindrical sleeve and one loop on the back of the plate over the cylindrical sleeve. A holding screw extends through a hole in the top jaw into a tapped hole in the base plate. The top jaw is curved from the front to the back so that tightening the holding screw will tightly hold the razor blade located between the base plate and the top jaw. A set screw radially in the sleeve secures the sleeve to the engraving point of a vibrating engraver. Therefore, operation of the engraver will vibrate the blade to aid in the scraping action.Type: GrantFiled: May 18, 1981Date of Patent: May 3, 1983Inventor: Milton C. Horst
