Abstract: 115,093. Higgins, A., and Cattle, P. S. April 26, 1917. Counters for articles; registration of selected values upon assembly of separate counters. -A series of separate electro-magnetically actuated counters or recorders is employed to register or record the number of articles passing through a weighing or measuring machine according to different ranges of weights or measurements. The movement of a part of the machine positions a multiple-contact switch to select and complete one of a series of circuits, according to the range o: movement of the part. Each counter or recorder recives unit actuation when the article passes from the machine, so that articles of value under 5, say, are registered on counter No. I, these of under 10 on counter No. II, and so on. The separate counters J<1>, J<2>, J<3>, J<4>, Fig. 1, are actuated by electro-magnets G', G<2>, G<3>, G<4> when a multiple switch A, after having been set to make contact through one of the several switches I. II, III, IV by the movement of the machine, returns to the position shown and completes circuits through switches H<1>, H<2>. The closing of switch III, for example, causes enervation of a magnet B<3> and the closing of the maintaining circuit for the counter-actuating magnet. G', and at the same time the breaking of the return circuits of the relay magnets B<1>, B<2> for the counters of lower ranges. A series of quick-break switches K<1>, K<2>. K<3>, K<4> having a slow-motion re-making device are arranged in the main current supply 4. They arc normally closed, but are opened by the armatures of their respective magnets G' &c. after the corresponding counter has received unit actuation. A counter J, magnet G, and switch li are shown in Fig. 4. The armature M of the magnet is mounted on a pivot i and is provided with an arm e adapted to rock a forked arm a on the counter spindle. The switch K is opened by a projection f<1> on a pivoted lever f, the other end of which is engaged by the armature M to rotate the lever against the resistance of a coiled spring j. A delay device, such as weights h at the ends of the lever to increase its inertia, is provided. One form of multiple-switch is shown in Fig. 3. An arm Q insulated from an arm T on a spindle R carries a number of pins Y of gradually increasing length adapted to dip into mercury cups. A second arm Q<1> carries two zero contact pins H<3>. The spindle R also carries an arm S connected by a link O with the steelyard of a weighing-machine, for example, and with an opposing spring or weight by a link P. A shell Z filled with shot, or other form of balance weight, may be fitted to the spindle R, and it may also be provided with a dashpot in the form of a paddle X moving in a mercury bath. In place of. or in addition to, the counters. apparatus for punching or typing a strip fed uniformly or after each operation may be employed. or the record may be made on the articles themselves. A bell signal may be fitted to the registering-device.
