Abstract

665,607. Weighing apparatus. BERKEL AUTO SCALE CO., Ltd. Feb. 18, 1948 [June 5, 1947], No. 4843/48. Class 143 Inaccuracies in the check links 11, 12 guiding the platter of a weighing scale are prevented from deranging the weigh beam knife edges and their supports by means of self-aligning knife edge bearings. The knife rest 17, Fig. 1, is slidable relative to the platter support 10 along a line substantially parallel with the axis of beam 8. In Fig. 4 the knife rest 25 is pivotally mounted on the platter support 10 which again is free to move relative to the beam. In Fig. 3 the self-aligning bearing is the beam fulcrum knife edge 23 which is slidable on the flat rest 24, and in a further modification, Fig. 5, similar adjustment is effected by a V-knife edge rest 26 mounted on rollers 27 for movement along the fixed block 22. In another modification (not shown), the check link 12 engages the beam in place of the platter support, and the beam fulcrum is supported as in Fig. 5.
