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.

  • Patent number: 7703210
    Abstract: A blade driving assembly for an adjustable hair clipper of the present invention comprises a movable blade holder, a spring, a spring holder and a push lever. The spring is disposed with a coiled portion secured on the spring holder, a first portion which exerts pressure upon the movable blade holder to bias the movable blade towards the stationary blade and a second portion which biases the spring holder towards a retracted position. The push lever is driven to move forward or backward by an external force, and a front end of the push lever abuts against the rear end of the spring holder in such a way to push the spring holder forward when the push lever is driven forward, and when the push lever is driven backward, the spring holder is biased by the spring to retract until the rear end thereof abuts against the push lever.

  • Publication number: 20090133264
    Abstract: An electric shaver has a pivotally mounted longhair cutter unit that is pivoted outward into an operating position by motion of an operating switch of the shaver via an actuator that also causes the cutting blades of the longhair cutter unit to extend from the longhair cutter housing. Because the longhair cutter retracts into the longhair cutter housing when the longhair cutter unit is folded shut, the sharp edges of the blades are protected.
