Apparatus for weight setting weighing devices

968, 608. Automatically manipulated loose weight weighing apparatus. BAKER PERKINS Ltd. Nov. 20, 1962 [Sept. 11, 1961], No. 32473/61. Heading G1W. Relates to an apparatus for automatically setting or changing the setting of the weight loading particulars of continuous feed weighers wherein different combinations of individual weights having different values may concurrently be deposited or removed from a weigh beam, each individual weight being added or removed with a cyclic periodicity which is directly proportional to the weight value, by means of a pivotal lever, one for each weight, pivotal between a depositing and a removing position by a means operative at said periodicity. The desired loading may be set remotely by manually operated switches or by punched card means (not shown). As shown, Fig. 1, a weighbeam 1 has a transverse bar 2 to carry weights 5 comprising a binary system of seven weights from 1W to 64W units, giving a total of 128 settings. Weight lifting levers 4 (e.g.4rW which is associated with weight 51W) are raised and lowered by respectively associated cams 8(Fig. 4) on shaft 9. The cam 81W (associated with the lowest weight unit 51W) is rigidly attached to the shaft 9, while the other cams 8 are rotatably mounted thereon. Each cam 8 has attached rigidly a pair of gear-wheels 11, 12 which respectively engages gears 13, 14 on a shaft 15. As shaft 9 is driven, via an electromagnetic clutch by a motor 10, the cam 81W and its gears rotate thus driving a cam 82W which in turn drives a cam 84W and so on down the line of cams. As gears 12 are half the diameter of gears 13 and gears 14 and 11 are equal each cam 8 rotates at half the speed of its preceding cam. Detector means are provided comprising a micro switch 24 associated with each weight lever and disposed so as to be operated by a switch cam 26, rigidly attached to each associated weight cam 8 to rotate with it, whereby a switch is closed when its associated weight is transferred to the weigh beam. (Alternatively photo-electric means may be used instead of switches). A remote control device (not shown) is provided which can be pre-set or conditioned (e.g. by punched card) to represent any desired weight loading within the weighing range of the system. When pre-set the device starts the motor 10 which rotates the cam shaft 9 so that weight levers 4 are raised and lowered concurrently to load and unload the weigh beam until the pattern of'closed switches 24 matches the pre-set pattern of t
