Title: Improvements in or relating to machines for sorting and totalling coins
IPC: G07D3/06
Filed: 1922-06-02
Abstract: 207,628. Lithgow, J., and Greenhalgh, H. June 2, 1922. Coins, separating and sorting.- In a machine for sorting and counting coins a rotatable disc 2 mounted in a casing 1 has pockets 3 to which coins are fed by a shoot 6 from a hopper 5. Each pocket 3 has a spring-pressed plunger 7 to push the coins outwardly against the casing 1, a curved bar 11 on the casing 1 engaging projections 12 on the stems of the plungers 7, holding them back against the springs as they approach the shoot 6 so that coins can be fed to the pockets 3. Coin shoots 13 .. 13f of different diameters are placed beneath the disc 2 to receive coins of different sizes from the pockets 3 as the disc rotates, each shoot being fitted with a counting device 15 comprising recessed discs placed side by side and marked to represent pounds, shillings and pence. The device 15 is actuated by a spring-controlled shutter 16 placed in the path of, and moved by, the coins falling down the shoot. Transfer mechanism comprises a pawl on each disc which engages a stop on the adjacent disc once in each revolution. To overcome the resistance of the shutter 16, a shaft 20 carries cams 25 which depress spring controlled rods 26 to actuate, through arms 28, fingers 29 behind the coins to force them past the shutters. The shaft 20 and the disc 2 are driven by the handle 21. In a modification, instead of a hopper 5 of V-shape, the hopper has an inclined bottom and is rocked by link mechanism between spring buifers, the coins passing through a V-shaped channel to the disc. The springs control the plungers through a pin and slot mechanism and are mounted exteriorly of the pockets, the coins passing from the pockets to the receiving shoots through coin slots which are normally covered by spring controlled shutters. As a pocket 3 approaches the requisite shoot for the coin it carries, a cam-bar of which the action is controlled by the size of the coin, moves the shutter tc uncover the shoot.

Apparatus for measuring variations in magnetic flux comprises a search coil 1 (Fig. 1), connected in series with a resistor 3 and the moving coil 2 of a torsion-free galvanometer, the current produced by the induced voltage in coil 1 due to a change in flux causing rotation of the moving coil 2 and the mechanically coupled moving plate 5 of a variable condenser, thus varying the A.C. volts drop across a resistor 11 from an H.F. oscillator 8, this A.C. voltage being rectified by detector amplifier 13 to oppose the voltage induced in the search coil 1, and bring the system to rest. The output current of the detector amplifier 13 is measured by a meter 20 having a heavily damped, torsion-free moving system comprising a metal disc 31 (Fig. 2), rotatable between two circular rings of prism-shaped magnets 21, 21<SP>1</SP> mounted on soft iron yokes, adjacent and opposite magnets being of opposite polarity. The rotation of its shaft is proportional to the quantity of electricity traversing the moving coil during the measurement, and therefore to the change in flux. Specification 587,459 is referred to.
