Abstract: 1,220,123. Weighing apparatus. T. SCHMIDT May 3, 1968 [May 12, 1967], No.21039/68. Heading G1W. In weighing apparatus comprising a pre-setting pointer 23 which can be set at an optional position according to the weight of material to be supplied and a weight pointer 4 which, in accordance with the weight of material supplied, moves until it cooperates with the pre-setting pointer 23 to cut-off the supply of material to the apparatus, the presetting pointer 23 is drivable according to a predetermined velocity function and the apparatus is provided with a device for determining the time period during which the pre-setting pointer 23 is driven. As shown, the pre-setting pointer 23 is arranged to be driven, under the control of a manual switch 31, simultaneously with a clock 32, the drive being stopped when the clock hand 33 is at a predetermined position corresponding to a required position of the pre-setting pointer 23. Then by manually operating a switch 35 supply of material is initiated from one of a plurality of silos 6, 7, 8 to a weighing receptacle 2 which is connected to the weight pointer 4 and when the pointer 4 cooperates with the pointer 23 supply of material is automatically terminated. Further materials may subsequently be directed to the receptacle 2 from the other silos after suitably re-positioning the pre-setting pointer 23 by means of the clock 32 and manual control switch 31. The pre-setting pointer 23 which may be driven by a synchronous motor may be rotatably mounted on a shaft co-axial with a shaft of the pointer 4 and may be provided at its end with a pair of adjacent units each comprising a light source directing a beam of light towards a photo-sensitive member. In operation of the weighing apparatus when material is being supplied from one of the silos, the pointer interrupts the light beam of one unit which causes the supply of material to be reduced to a continuous or intermittent dribble and then subsequently interrupts the light beam of the other unit which causes complete cut-off of the supply. Instead of manual control, the weighing apparatus may be provided with a program control which is arranged to drive suitably the pre-setting pointer 23. The silos 6, 7, 8 may be provided with hydraulically or pneumatically actuated closure flaps 9, 10, 11 which are controlled automatically by the pointers 4, 23. An arrangement for effecting tareing of the weighing receptacle may be provided and in a further embodiment the pre-setting pointer may be driven for a time period which is pre-set on the clock 32.
