Abstract

517,972. Change-giving apparatus. BRECKNELL, MUNRO & ROGERS (1928), Ltd., and DOLMAN, H. J. Aug. 6, 1938, No. ' 23256. [Class 27] In change-giving vending apparatus means is provided to keep the change coin reservoir adequately filled. Fig. 1 shows a reservoir 4 in which change coins are stored in pile formation, a pusher 50 being automatically operated to eject coins 5 as change into a tray 7. When the reservoir 4 becomes nearly empty, an endless conveyer belt 11, furnished with claws 14, is moved to lift coins from a bulk container 9 and drop them into'the top'of the reservoir 4 by way of an inclined channel. When the correct purchase money is inserted a delivery shaft 3 is rotated to eject the article bought, and when change is required the shaft 3 is coupled in known manner to mechanism associated with the pusher 50. The means for actuating the conveyer belt 11 consists of a pawl 20 pressed by a spring 23 into engagement with a ratchet wheel 19 on the shaft 3, so as to couple a disc 18 carrying the pawl to a sprocket wheel over which passes the conveyer operating chain 17. In its rotation the pawl 20 strikes against a spring-lifted detent 27 pivoted at 29, and is not freed till the detent is drawn down by a solenoid 31 energized by the closing of contacts 32 controlled by -a feeler 35 swinging into the coin reservoir 4. A plurality of reservoirs 4 may be provided, each having its conveyer 11, and in a modification the conveyers may be driven by a separate motor, instead of from the shaft 3. The feeler 35 may be duplicated, the conveyer 11 being started only when the lower feeler closes its contacts, and being stopped only when the upper feeler is moved by the accumulated pile of coins to opens its contacts.
