Abstract

451,977. Weighing-apparatus. TOLEDO SCALE MANUFACTURING CO., Toledo, Ohio, U.S.A. April 26, 1935, No. 12548. Convention date, Feb. 2. [Class 143] In a weighing-apparatus employing spring load-counterbalancing means 9, 10, zero variation and variation, under load, in the movements of the indicating pointer due to the effects of temperature changes on the springs are compensated for by transmitting the movements of the spring-loading means to the indicator by a flexible member, the flexure of which is varied according to the temperature. The indicator rack 34 is mounted upon a flexible member in the form of a blade spring 29 supported at its opposite ends on a light spring 31 and on a load-actuated equalizer bar 17. A thermosensitive element 42 bears upon the blade spring to regulate the extent of its flexure. A rise or fall of temperature moves the end of the thermosensitive element to the right or left respectively to vary the point of flexure of the blade spring and thus maintain the constancy of the zero position of the pointer, and of its movements under load. The zero position of the pointer may be adjusted by a screw 45 supporting the light spring 31. Dashpots 24, 25 are connected to the equalizer bar 17.
