Abstract

695,976. Spring balances. HARPER & CO.; Ltd., J., and CROWLEY, C. Nov. 1, 1951 [Nov. 7, 1950], No. 27135/50. Class 143 In Fig. 1 the scale pan 22 of a domestic weighing machine is supported by a stem 20 located by knife-edge 25x at one end of a cantilever spring 13. Stem 20, which is maintained upright by pivoted link 17 and by a keeper 27 attached to spring 13, moves in a vertical direction upon application of load to operate, through a link 42 and a slotted cam 47, a pointer 28 over a scale 36 which is visible through a window 41. Pointer 28 is pivoted at 30 on a bracket 31 and provided with a counterweight 29. Cam 47. is so shaped that the scale is linear. The positions of link 42, bracket 31 and scale 36 are adjustable by screws 43, 32 and 40 respectively. In a modification for heavier loads an additional pivoted link 48 is provided, knife-edge 25<SP>x</SP> and keeper 27 being dispensed with.
