Abstract: 28,562. Reith, G. C., and Flade, G. Dec. 7. Coins, testing.-The apparatus may be used to detect any imperfection in the minting of coins, or to reject spurious coins from coin-freed apparatus. A pivoted coin-director 84 is freed by the insertion of a coin of correct dimensions and drops into the position shown in dotted lines, Fig. 4, so as to direct the coin into a shoot 88 leading to an alarm or indicator, while imperfect coins, being unable to free the director, pass outside the shoot 88 and are retained in the machine. The director is pivoted at 85 to a fixed frame 31, and is connected at 86 to a weighted slide 41, which works between fixed plates 39, 42 and is normally held in the raised position by the projection of a sleeve 50 and bolts 62, 62<a> into sockets in the plate 39. The inserted coin is supported on a pin 24 between circular knife - edges 23, 38 formed on a slide 22 and the frame 31 respectively. The operator pulls back a handle 13 in the direction of the arrow, thereby moving forward the slide 22 through a spring-controlled plunger 26 and link 20, the coin passing from the pin 24 on to a pin 96 mounted in the frame 31. During this movement, the raised centre of the coin engages a spring-controlled pin 34, and the knife - edges 23, 38 engaging the depressed portion of the coin inside the rim, the pin 34 is moved forwards sufficiently to bring the sleeve 50 flush with the surface of the slide 41. Simultaneously, pins 26<a>, 26 on the slide 22 engage a pin 60<a> and the rim of the coin respectively, thereby moving forwardpins 60a, 60 and bringing the bolts 62, 62<a> flush with the surface of the slide 41, which thereupon falls under the action of a weight 75, thereby lowering the director and moving a contact 92 into the coin shoot 88. As soon as the pivot 17 passes the line of centres 12, 21, the slide 22 begins to move rearwards, the pin 34 pushing the coin off the pin 96 into the director 84, whence it passes down the shoot 88 and closes, through contacts 92, 91, the circuit of an alarm 95. To prevent fraud, a lever 28 operated by the pivot 17, serves to force down the coin if adhesive has been applied. If too thick a coin has been inserted the knife-edges 23, 38 cannot approach one another sufficiently to free the bolt 62<a>; in the case of a worn coin, the bolt 62 is only partly withdrawn, and if a counterfeit of insufficient central thickness has been inserted the pin 34 is not moved sufficiently to free the sleeve 50. Two pins 67, Fig. 6, carried by a rocking frame 70 mounted in the rear plate 42, engage respectively flat and raised portions of the coin, but, if a flat disk has been inserted both pins project to the same extent and prevent the complete movement of the pin 34 and sleeve 50. On the release of the handle 13, a dash-pot 2, which is connected to the pivot 17 by a link 18, returns the parts to the normal position, the slide 41 being raised by a lever 77 operated by the nose 83 of the handle. To prevent the passage of slightly worn coins, the part 41<b> of the surface of the slide 41 is not quite flush with the surface of the plate 39, and the various parts may be adjusted by means of screws. A pin 51, passing through the pin 34, may be set to engage the raised head on the coin and thus cause the rejection of all coins inserted with the other side to the pin.
