Title: Improvements in weight totalising apparatus
Inventor: GAMBLE JOHN ANTHONY
IPC: G01G11/20
Filed: 1965-02-09
Abstract: 1,148,301. Weighing apparatus. W. & T. AVERY Ltd. May 6, 1966 [Feb. 9, 1965], No.5557/65. Heading G1W. Weight totalizing apparatus for totalizing loads transported by a conveyer comprises a first element for responding to the magnitude of an instantaneous load, a second element for responding to the speed of travel of the conveyer, an arrangement for integrating the responses of the first and second elements to totalize the total load transported by the conveyer, and a checking device comprising a third element for providing a predetermined response representative of the magnitude of a trial load, a fourth element for responding to the speed of travel of the conveyer, and an arrangement for integrating the responses of the third and fourth elements, the apparatus further comprising an arrangement by which the two integrated responses can be compared. As shown, the totalizing apparatus which is of a type similar to that described in Specification 936,933 comprises cams 12, 13 which provide an integrated reading of a load transported by a conveyer belt (not shown) and the checking device comprises a pair of cams 14, 15 which are manually settable in accordance with a known load. The known load on being transported by the conveyer belt causes the cams 12, 13 to provide an integrated reading which is compared with a reading obtained from the pre-set cams 14, 15. The comparison may be effected by arranging that the sets of cams 12, 13 and 14, 15 each drive a disc 19, 18 respectively which discs are of different diameter and are mounted coaxially. Differences, if any, in the integrated readings derived from the different sets of cams 12, 13 and 14, 15 when the known load is transported by the belt are therefore clearly indicated and adjustments, if necessary, can subsequently be made.
