Pivotally actuated speed control means of an apparatus

In apparatus having a power source, an accelerating element, and control means connected to the accelerating element for varying the speed of the apparatus in response to movement of the accelerating element, said control means having a start switch having an actuating means, a bypass switch having an actuating means, and a potentiometer having a pivotally movable control element, each of said switches and potentiometer being associated with the accelerating element and controllable in response to movement of the accelerating element, the improvement comprising:

• an actuating element being pivotally movable between a first position at which the actuating element is spaced from the bypass switch, in contact with the actuating means of the start switch, and the actuating means of the start and bypass switches are open and a second position at which the actuating element is spaced from the start switch, in contact with the actuating means of the bypass switch, and the actuating means of the start and bypass switches are closed, said actuating means of the start switch being at the closed position and said actuating means of the bypass switch being at the open position in response to the actuating element being at intermediate positions;
• means for connecting the actuating element to the accelerating element, said actuating element being pivotally movable in response to movement of the accelerating element;
• and
• a tie bar having one end connected to the pivotally movable control element of the potentiometer and the other end connected to the actuating element at locations sufficient for controllably moving the control element and controlling the potentiometer in response to movement of the tie bar by the actuating element.
