1. A weighing apparatus comprising:
- a housing;
a weighing mechanism carried by the housing;
the housing having a viewing region;
a load receiving platform operatively associate with the weighing mechanism for receiving a load to be weighed;
a dial, including a face associated with the viewing region, the face of the dial bearing indicia for indicating the weight of the load received by the platform;
indicator means for moving relative to the dial in response to the weight of the load received by the platform and for providing, in cooperation with the weighing mechanism and the indicia of the dial, an indication corresponding to the weight of the load; and
magnifying means operatively associated with and movable with the indicator means for magnifying only a limited portion of the face of the dial in proximity to the indicator means.

Abstract
A weighing apparatus including a load receiving platform, a dial, and a moving indicator. The dial includes a face bearing various indicia for indicating the weight of a load placed upon the platform. A magnifier is operatively associated with the indicator for magnifying only a limited portion of the face of the dial in proximity to the indicator. A lamp, carried by the indicator, illuminates a limited portion of the face of the dial in proximity to the indicator. A switch actuates the lamp upon placement of a load upon the platform.

17. A weighing apparatus comprising:
-
a housing; a weighing mechanism carried by the housing; the housing having a viewing region; a load receiving platform operatively associated with the weighing mechanism for receiving a load to be weighed; a dial, including a face associated with the viewing region, the face of the dial bearing indicia for indicating the weight of the load received by the platform; indicator means for moving relative to the dial in response to the weight of the load received by the platform end for providing, in cooperation with the weighing mechanism and the indicia of the dial, an indication corresoonding to the weight of the load; illumination means for illuminating at least a portion of the face of the dial in proximity to the indicator means; switch means for actuating the illumination means upon the load being received by the platform; the switch means including a first member operatively associated with the indicator means and a second member operatively associated with the housing; the first and second member being in a non-connected, non-conductive orientation relative to each other when the weighing aooaratus is in a non-load bearing state; the first and second member being in a connected, conductive orientation relative to each other upon movement of the indicator means from the non-load bearing state in response to the load received by the platform; the indicator means including a rotating member, the rotating member rotating in response to the load received by the platform, the degree of rotation being dependent upon the weight of the load received by the platform; the first member comprising a partially open conductive ring including an open region; the partially open conductive ring being attached to the indicator means in a position substantially surrounding the rotating member; the second member comprising a conductive arm including a first end and second end; the first end of the conductive arm being attached to at least a portion of the housing; the conductive arm being spring-biased and positioned such that at least a portion of the conductive arm proximate to the second end remains in electrical contact with the partially open conductive ring when the apparatus is in a load-bearing state; and the partially open conductive ring being oriented relative to the conductive arm such that the open region aligns with the second end of the conductive arm when the weighing apparatus is in the non-load bearing state, wherein an open circuit is created between the conductive arm and the partially open conductive ring. - View Dependent Claims (18)
