Abstract

308,246. Toledo Scale Co., (Assignees of Beard, J. H. and Hem, H. 0.). March 20, 1928, [Convention date]. Weighing-apparatus; coin action, mechanical - connection; coin-discharging mechanism.-In a coin-controlled weighing scale in which h the weighing mechanism is normally locked against operation by mechanism releasable by a coin engaged and moved member, the coin itself being engaged and moved by a manually actuated element, the coin engaged member is connected to the weighing mechanism and is displaced, on movement of this mechanism, to discharge the coin. The draw-rod 8, Fig. 5, connecting the platform to the counterbalancing mechanism is normally locked against movement by being connected at 13 to a lever 12 having a toothed portion 15 which is engaged by a toothed pawl 16 pivoted at 17. After prepayment, the pawl 16 is released by the upward movement of a lever 20 which is actuated by a bell-crank lever 23, Figs. 2 and 6, connected to a movable frame 24. The frame 24 is connected by an adjustable link 25 to the lever 12 and is formed with a pair of toes 26 on which the coin 36 inserted through a slot 28 rests. The slot is guarded by a pivoted baffle 30 which prevents the coin, when dropping down a slope 29, from overshooting abutments 27 on the frame 24. A plunger 33 is then pressed in against spring action and a finger 35 thereon engages the coin pressing it against the abutments 27 to push back the frame 24 and cause the lever 23 to release the weighing mechanism. When the weighing mechanism moves under the action of the load, the link 25 rocks the front end of the frame 24 downwards to discharge the coin to a shoot 37. The toes 26 on the frame 24 may be moved apart so that small coins will drop betweem them, or they may be pressed together so that the scale may be operated by small as well as large coins.
