Abstract:
A reversible ratcheting electric power tool adapted to be coupled to a source of electric power having two source terminals, the tool comprising:a reversible electric motor having an output and two motor terminals,a reversible ratchet assembly coupled to the output of the motor and adapted to be coupled to an associated driving device,a manually operated reversing mechanism coupled to the ratchet assembly for selectively controlling the ratcheting direction thereof,an electric control circuit coupled to the motor terminals and including two direction control switches each having a normal deactuated condition in which the direction control switches are disposed for respectively connecting both of the motor terminals to one of the source terminals, and being operable to an actuated condition in which the direction control switch is disposed for connecting an associated motor terminal to the other of the source terminals, the switches respectively controlling forward and reverse directions of operation of the motor, andtwo switch actuators carried by the reversing mechanism for respectively actuating the direction control switches one at a time substantially simultaneously with selection of the ratcheting direction, so that the motor direction is compatible with the ratcheting direction,the electric control circuit including an on-off switch connected in circuit with the direction control switches and adapted to be connected to the associated source of electric power,each of the direction control switches and the on-off switch being actuatable independently of the others.
