Abstract: A hair cutting device includes a cutter having a guard moveable relative a blade carrier to vary a cutting length within a cutting length range. The cutter has an actuator moveable between first and second positions to move a follower element and the guard to vary the cutting length between two extreme length settings. The cutter is pivotable relative a housing of the cutting device between an open position and a closed position for cutting. The follower element is configured to cooperate with the actuator so that, when the cutter is in the open position with the follower element and guard in the first position, but the actuator is in the second position, pivoting movement of the cutter to the closed position causes the actuator to drive the follower element and the guard to the second position.

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.
