ABSTRACT:
A motorized shingle removing hand tool comprising a blade assembly shiftable between a normal extended position and a retracted position. The blade assembly is biased to its normal extended position and is shifted to its retracted position by a motor driven cam which thereafter allows the blade assembly to be driven to its extended position by the biasing mechanism. The tool comprises a base on which the motor is mounted. The blade assembly comprises a blade and its support mechanism which is mounted in bushing blocks affixed to the base. The base is provided with an openable cover to keep the motor, the cam, the blade support mechanism, the biasing elements and the bushings free from dirt and foreign material. The tool includes an adjustable handle and an actuating trigger with an associated variable speed control switch, and a carrying strap.
