Abstract

378,734. Coin - freed apparatus. HARPER, P. S., Adelaide House, Ashurst Walk, Croydon. Dec. 4, 1931, No. 33582. [Class 27.] Testing coins.-Relates to magnetic coin detector mechanism, applicable to coin-freed machines, of the kind wherein eddy currents are set up in the coins when these pass through a magnetic field, thereby causing the coins to leave a shoot with different trajectories, according to their materials, and pass to different receptacles. According to the invention, the eddy currents are set up by a pair or pairs of permanent magnets 2, Fig. 1, one of each pair being located wholly on one side of the coin shoot 1, with its poles opposed to the other magnet fixed on the other side of the shoot, the opposed poles being on the centre line of the coin path. As shown, the magnets may be arranged in staggered formation. The poles 3 of each magnet are turned at rightangles, as shown in Fig. 3, to take into holes in the sides of the shoot 1.
