Abstract: 452,169. Weighing-apparatus. ASHWORTH, SON, & CO., Ltd., ASHWORTH, W. S., and ASHWORTH, E. F., Midland Iron Works, Dewsbury, Yorkshire. May 3, 1935, No. 13167. [Class 143] Loose-weight apparatus.-Relates to weighing- apparatus of the kind wherein capacity weights are added to or removed from a weighing lever or steelyard in order to increase or decrease the weighing capacity of the apparatus, the depositing or removing mechanism being connected to a movable chart to change the major weight units of the indicating mechanism. The invention consists in depositing or removing the capacity weights by the rotation of a shaft acting through a radially displaceable member, the shaft being overbalanced so that the actuating means cannot be left in a position other than that required to be occupied when a capacity weight is definitely in or out of operation. The load is applied by a rod 3 to a steelyard 4 fulcrumed on a knife-edge 5 and connected by a rod 7 to the indicating mechanism. A balance weight 9 is suspended from the steelyard and is adapted to receive one or both of two capacity weights 10, 11 to increase the weighing range of the machine. The capacity weights when out of action are suspended by plates 12 supported by a slidable cross-head 14 resting upon a cam 18 secured to the actuating shaft 19. The shaft is rotated to deposit the capacity weights by means of a hand lever 20 co-operating with a notched gate 21. The shaft carries a weight 22 which tends to rotate the shaft to a position where the hand lever 20 abuts against one of the notches of the gate, that is, prevents the inadvertent setting of the hand lever and the capacity weights to a midway position. A flexible cable 24 connecting the shaft to an annulus 25 bearing major weight numerals changes the numerals appearing at apertures 27 as the capacity weight are changed. Specification 452,168 is referred to in the Provisional Specification. Locking-mechanism.-The steelyard 4 is locked by means of a locking-lever 29 pivoted coaxially with the steelyard. The locking-lever may be raised by a crank and handle 33 so as to clamp the steelyard between an adjustable stop 30 and the end of the locking-lever.
