Abstract
726,035. Weighing apparatus. SALTER & CO., Ltd., G. Feb. 23, 1954 [June 26, 1953], No. 17729/53. Class 143. Relates to spring-balances in which the loadsupporting part is connected to a fixed part by a parallel-motion system, and consists in actuating the indicator by a member attached to or controlled by a member of the parallel-motion system, the member tilting. As shown in Fig. 3, the goods pan 13 is supported on a column 39 coupled by leaf springs 7, 8 to a fixed column 3; attached'to spring 7 is a curved lever 23 so that as spring 7 flexes, lever 23 tilts and its tip 23a, Fig. 7, moves, the engaging pointer 30 following it under the constraining action of a light spring 36. For taring, screw 20 may be used to set the pointer to zero when an empty container is on the pan, so that a loaded container will cause the pointer to register the tare weight. Range may be adjusted by screw 32, Fig. 7, by which the point of engagement between member 25a and lever tip 23a is moved nearer to or further from the point about which pointer 30 pivots so that pointer 30 makes a smaller or greater movement for a given deflection of lever 23. In a modification, Figs. 8 and 9, the tilting lever 47 is engaged by a bell crank lever 54, 53 urged against lever 47 by a light spring 56; taring is produced by moving the base 52, on which lever 54, 53 is pivoted, by screw 57.
