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 and a shaft member operatively connected to and extending from the motor, the shaft member including a spring for supporting the pan element. A plurality of collapsible support members are secured at one end thereof to the frame and each have at their opposite ends a device that is adapted to receive and lift one of the weight elements when the support member is in an extended and non-collapsed position. A camming arm is secured to the shaft member and 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 the camming arm into contact with successive collapsed support members in a step-by-step manner to place a number of the support members in an extended position and lift a corresponding number of the weights substantially equal to the weight of the load.
