519,707. Coin - freed machines. ROSSITER, F. E. Sept. 30, 1938, No. 28402. [Class 27] In coin-freed machines the coins fall down a shoot 5 and pass partly through a slot in a sliding member 2, coming to rest on the inclined surface 6. The stop 7 is moved axially on the threaded bar 8 until the correct combination of coins 24 forms a rigid bar between the stop 7 and the pawl 10 either directly or through the intermediary of a pivoted stop 9. Thus when the drawer or sliding member is moved in Fig. 1 at right angles to the plane of the paper the coins release the pawl and allow the movement to proceed. During the movement the pivoted stop 9 is engaged by the fixed ramp 21 to release the coins and the latter drop into a coin receptacle as soon as they move laterally off the shelf 6. On the return movement of the drawer a spring 17 re-engages the pawl 10. Meanwhile the movement of the drawer is used to deliver articles on the intermittently - operated - gate - and - gravity - escape - principal. The forward movement of the drawer removes the lowest article 13 from the pile and drops it through an opening 15 for delivery; a second member 16 meanwhile moving forward to support the rest of the pile. On the return movement' another article is lowered into the slide for delivery next time.
