Abstract: 630,217. Weighing-apparatus. AVERY, Ltd., W. & T. (Bohannan, R. S.). Jan. 25, 1947, No. 2367. [Class 143] The load supporting platform 1, Fig. I, is secured to a structure 3 provided at each corner with a laterally extending bracket 4 which is supported from a top plate 35, Fig. III, of a capsule 6 by means of a U-bolt 38 and a C-shaped member 37 which embraces said capsule. The bottom plate 30 of each capsule is supported by a similar C-shaped member 42 swingably suspended from a rigidly anchored hook 5. By this arrangement the capsules each serve as a freely suspended link and are not distorted by horizontal displacement or uneven loading of the platform 1. Hydraulic fluid displaced from each capsule under load is transmitted through a pipe 8 to a receiving element 9 which converts the hydraulic pressure into mechanical force and transmits it through a strut 12 to a gathering lever 14 which is connected by a steelyard rod 18 to a steelyard 20 having an adjusting weight 23, a counterpoise weight 22 and a beam locking mechanism 26.
