ABSTRACT:
A weighing device is disclosed which comprises a frame, a pan element for supporting a load to be weighed, a channel member connected to the pan for retaining a plurality of weight elements in a vertically movable manner, a motor supported within the frame, a shaft member operatively connected to and extending from the motor and a plurality of support members having top end portions adapted to receive and lift one of the weight elements. Two arms are secured to the shaft member and each extends in a direction toward the support members. A switch is provided for energizing the motor when the pan is depressed by a load. The motor turns the shaft member and guides each of the arms alternately into contact with successive support members in a step-by-step manner and thereby lift a corresponding number of the weights substantially equal to the weight of the load.
