  • Patent number: 8341846
    Abstract: The hair clippers use a self-contained motor-driven adjustment mechanism to adjust the relative position of the stationary and reciprocating blades of a common type of blade set. Two momentary switches operable by the thumb of the hand holding the clipper afford a barber total automatic adjustment with the clipper itself in an on or off condition. Since the small gear motors used for the adjustment are brush type or brushless permanent magnet motors which are operated by direct current, the adjustment feature is most compatible with cordless clippers already using an on-board DC source in the form of a re-chargeable battery to drive the reciprocating blade. The invention will be described as a modification of a cordless clipper, although AC driven corded type clippers can also be modified with this feature by the addition of an on-board AC to DC power supply for the adjustment motor.

  • Publication number: 20030079351
    Abstract: A deflectable safety shield extends transversely across a cutting plane in a protective guard position completely overlying the cutting edge of a utility knife. A portion of the shield extends over-center with respect to the cutting edge, thereby tending to hold the shield in the guard position in response to contact of the shield against the operator at the normal angle of engagement during follow-through that accompanies rapid slicing hand movements. The shield is resiliently biased for movement to the guard position by a torsion spring. An outwardly-turned flange portion of the shield provides an angularly offset leverage point for reacting the torsion spring when the operator desires to perform a cutting operation. The shield swings away from the cutting plane automatically in response to pressure engagement of the offset flange portion against the box surface, thus exposing the cutting edge.

  • Patent number: 5237750
    Abstract: A hair clipper includes, in addition to a cutter head, a hair entrapping member and a hair pressing member which are both movable relative to a cutting edge of the cutter head. The cutter head comprises a toothed stationary blade and a toothed movable blade. The movable blade is driven to reciprocate in shearing engagement with the stationary blade for shearing hairs therebetween. The hair entrapping member is movable between an open position and a closed position. In the open position the hair entrapping member is spaced away from the cutting edge of the cutter head, thus permitting hairs to enter between the hair entrapping member and the cutting edge. In the closed position, the hair entrapping member is held close to the cutting edge to thereby seize the hairs therebetween for shearing the hairs.
