299,826. Automatic Scale Co., Ltd., and Blich, E. L. Aug. 2, 1927. Pendulum-weight apparatits.-In an automatic or semi-automatic weighing - apparatus the lever mechanism, resistant mechanism, indicating mechanism and the housings or casings therefor are mounted on or supported directly from a metal bar which constitutes a base and support for the whole of the apparatus. The bar 10 constituting the base of the apparatus is supported at each end on an adjustable foot 11<a> and has secured to its upper surface two brackets 21, 9, supporting respectively a pendulum lever 23 with pointer, and the fulcrum knife-edges 6 of the scale beam 7. The pendulum lever 23, which may be formed of pressed sheet metal, is actuated through a flexible band 18 and cam 19, and is adjustable relative to the cam by means of screws 24. A screw 26<a> screwing into the pendulum weight 25 is provided for adjusting the effective movement of the pendulum. The scale pan 14 is supported on the beam by a U-shaped strap 13<a> formed as a pressing and connected by oppositelydirected arms to the dash-pot 15 and to a check arm 34. The bracket 9 is provided with lateral ears for adjustable feet 11 and also forms a support for the dash-pot. Casings.-The housing 12 for the base lever mechanism is attached by screws 12<a> and 22 to the brackets 9 and 21.. The indicator casing 29b which is divided vertically into two parts secured together by screws 30, Fig. 5, and distance pieces 31, fits over a flange 12<b> on the base housing. The indicator casing and the base housing are made from sheet metal pressings. The two parts of the indicator casing may be connected together and to the base housing by spot welding. A base plate 38 secured to the bar 10 closes the under side of the scale.
