Abstract

1,162,425. Weighing apparatus. SARTORIUSWERKE A. G. Jan. 12, 1967 [Jan. 28, 1966], No. 1812/67. Heading G1W. A bearing assembly for a weighing apparatus comprises knife edge members 6 mounted on one part of the apparatus and co-operating V- bearings 8 mounted on another part of the apparatus, the knife edge members 6 being restrained from movement in the direction of the knife edge relative to the bearings 8 by elastic elements 13 whose longitudinal axes are aligned with the line of contact between knife edge members 6 and the bearings 8. The elastic elements may be in the form of a pair of tension or compression springs Figs. 3 and 4 (not shown), each having one end connected to a bracket (26) which is fixed to one of the parts of the apparatus and the other end connected to a bracket (24) which is fixed to another part of the apparatus. Alternatively, the elastic elements may be in the form of a single torsion strip or wire, or in the form of a pair of torsion strips or wires Fig.2. Spring strips 14 may be provided to tension the elastic elements 13. The weighing apparatus provided with such bearing assemblies may comprise a beam (4, Fig. 1, not shown) to which knife edge members (3) and 6 are secured and a pan carrier 7 having a pivoted link arrangement (9, 10, 11). A scale (5) provided at one end of the beam (4) may be projected on to a screen.
