Abstract

234,935. Wollaston, H. J. Buchanan-. March 15, 1924. Pendulum-weight apparatus. - A weighing- machine comprises an eccentrically weighted roller bearing on a horizontal surface, a weighpan connected either directly or indirectly to the roller at a point on one or both end surfaces, the distance of the said point from the axis of the roller being adjustable, and a pointer and chart for indicating the weight of an object in the weigh-pan. As shown in Fig. 1, the invention comprises a roller a eccentrically weighted by an insertion b of heavy material, and connected to a weigh-pan O by a cord I' adapted to pass over one of a series of projections P. The major part of the load is balanced by a weight W movable along a graduated arm C<1> projecting from the roller. The minor part of the load is balanced automatically by movement of the roller, and is indicated by the cord I' which registers with a chart S mounted on an arm C carried by the roller. In a modification, Fig. 2, the weigh-pan O is suspended from arms C<2> projecting from the roller and forming extensions to the end surfaces. A pivoted, counterweighted pointer I<2> registers with a chart S to indicate the weight. In further modifications, the weigh-pan is suspended from a lever which is in turn connected to the roller, and the weight is indicated by some part or extension of the lever registering with a chart on the roller.
