Appl. No.:

6/513368

Inventors:

Harvey S. Gitlin - Ambler PA
John J. Duffy - Ambler PA

International Classification:

G07F 508

US Classification:

194 1G

Abstract:

The coin slide includes a fixed body with an integral flange and an integral handle and slide plate which is reciprocal on the body and through the flange. The handle is provided with a plurality of elongated openings within which are fitted interchangeable functional or nonfunctional cores. The functional cores are sized to receive coins of predetermined denomination and can be made to accommodate any size coin, even foreign coins. An interchangeable bridge includes downwardly exposed ramps or cams to accept or check coins of predetermined denomination. The interchangeable cores and interchangeable bridge are utilized to quickly and easily adjust to any desired price which can be computed when using from one to five coins. The body terminates rearwardly in a notched trailing edge whereby coins in alignment with the notches will drop first, and the drop of coins that are not aligned with the notches will be delayed.
