Abstract: 21,683. Burdick, C. L. Sept. 23. Counters for coins. -In an apparatus for counting coins of various denominations, and registering their total value, there is a conveyer with a series of pockets for seating the coins in particular positions, depending on their size, and for taking them past the registering- point, where the coins engage an abutment-lever and impart a differential movement, corresponding to the value of the coin, to the counting-mechanism. An elevation of the apparatus is shown in Fig. 1. The coins are placed in a tray m and fed into a hopper n. When the handle is rotated, the coins fall into one or other series of pockets r of the conveyer f as it moves upwards, and a spring 66 ensures that only one coin enters a pocket at a time. The upward movement brings the notches, in the advancing edge of each pocket, in turn over the projections 11 on one or other of the spring-controlled abutment-levers 12 ; the projections enter the notches and lie in the path of the coins to transmit the movement thereof through the lever 12, cross-head 9, connecting-rod 8 and crank 7 to a sleeve 5 or 6 provided with an arm 33 or 34 respectively, which strike a pin 35 on an arm 36 and through a pawl 37 actuate the ratchet-wheel 39. The sleeve 5 is fixed to a spindle 4 and the sleeve 6 is mounted loosely thereon. To the ratchet wheel 39 is attached a star-wheel 43, marked with graduations to show increments of sixpence through an aperture in the casing 48. A pin 50 on the star-wheel 43 is adapted to engage a star-wheel 51 once every revolution, and through bevel-wheels to advance a counter 54 by one unit. The instant after the coin has moved the abutment-lever to its full extent, a cam 30 on the conveyer rocks a pivoted lever 22 and causes the rollers 26 to eject the coin down the shoot 32. The counter-actuating parts are returned by a spring 21. The projections 11 of the levers 12 are prevented from entering the pocket, from which the coin was ejected, by cams 18 on the conveyer which engage the rollers 20 mounted on an arm attached to the levers 12. An automatic adjustable stop is provided to arrest the mechanism after a certain sum of money has been counted. A pinion 55 fixed to the spindle of the star-wheel 43 gears with a disk 57 having a series of holes 58 and a hole 59 nearer the centre of the disk. A rod 63 is provided with a pin to engage one or other set of holes, and is pivoted at its lower end to a double-armed lever 60 having a detent 61 for engaging the ratchet-wheel 2 on the main shaft. When the pin on the rod 63 engages one of the holes, the rod is raised, the detent locks the main shaft, and the counter is arrested. The machine may be stopped during the process of counting a coin when the value of the coin is such that only a fraction of its value is required to make up the desired amount. The amount to be added is shown by means of a pointer, attached to the arm 36, moving over the scale 68, Fig. 7. The lower part of the conveyer passes over a plate j which is provided with holes to allow three-penny pieces to fall without being counted.
