[Class 27.] Coin action, thrust, with delivery proportionate to value of coin.- In meter prepayment mechanism, a plate u, connected through free - wheel mechanism with differential quantity mechanism (not shown), is provided with abutments w, x, y set at different angular and radial positions and adapted to be engaged selectively according to the diameter of the coin inserted in the rotable coin-pocket b by a driving member d pivoted to the coin-pocket, the arrangement being such that the movement imparted to the plate u, and consequently the amount of the commodity, is determined by the diameter of the coin inserted. A further abutment z on the plate u is engaged by the driving member d, when the coin is discharged, for return of the coin pocket to its initial position. Specification 374,877 is referred to. Coin-slit closing-devices.-The coin-pocket b is mounted on a plate g loose on a boss h of the operating handle j, and has an arcuate slot o engaged by a pin n on a plate k fast with the handle j. Plate g is held by a latch p during initial rotation of the handle so as to permit the plate k to close the coin slot c, the latch being subsequently disengaged by a ramp r on plate k. Coin-discharging mechanism.-A pivoted closing member 2 on the holder b is deflected to release the coin, upon completion of movement of the holder, by engagement with a fixed stop 4.
