US Patent:

53886801, Feb 14, 1995

Filed:

Feb 25, 1992

Appl. No.:

7/841379

Inventors:

John A. Hird - Dallas TX
Mark E. Kerr - Wylie TX

Assignee:

Intellicall, Inc. - Carrollton TX

International Classification:

G07F 104

US Classification:

194345

Abstract:

A coin handling system comprising an improved coin chute (115) for guiding coins in a coin operated machine is provided comprising a first chute piece (122) and a second chute piece (123), each forming an opposite sidewall of the chute (115). An internal bevelled surface (129) is formed on the backwall (140) of one of the chute pieces (122, 123) so that foreign objects forced into the chute (115) and impacting the backwall (140) will cause the chute (115) to separate into the chute pieces (122, 123) and thereby cause the foreign object to leave the chute (115). Additionally, external bevelled surfaces (144, 148) are formed on the chute pieces (122,123) so that if a foreign object impacts the outside of the chute (115), the chute (115) separates into the chute pieces (122, 123) and allows continued movement of the foreign object. Thus, the foreign object does not become caught in the coin chute (115). In another aspect of the invention, ridges ( 130) are formed on the backwall (140) of the chute (115).

International Classification:

G07F 104

US Classification:

194345

Abstract:

A coin handling system prevents jamming of the coin chutes of coin operated machines and keeps foreign objects out of coin validators and other internal mechanisms of coin operated machines. A coin chute 15 guides coins into the coin validator 24. An exit end of coin chute 15 is moved from a rest position above the coin validator 24 to a position above a return chute 25. Coin chute 15 then separates into two pieces, causing large foreign matter to fall out of the coin chute 15. Foreign objects that are pushed into coin chute 15 are forced out of coin chute 15 by slots 30 formed on the back edge of coin chute 15. Foreign objects are thus prevented from going further into coin chute 15 and coin validator 24. A bevelled edge 29 is formed on an edge of chute piece 23, one of two pieces forming coin chute 15. Foreign objects are pushed into coin chute 15, it impacts bevelled edge 29, causing coin chute 15 to separate into two chute pieces.

Intellicall, Inc. - Carrollton TX

International Classification:

G07F 104

US Classification:

194345

Abstract:

A coin handling system is provided to prevent the jamming of coin chutes used in coin operated machines and to keep foreign objects forced into coin chutes out of coin validators and other internal mechanisms of coin operated machines. The invention comprises a coin chute 15 for guiding coins into a coin validator 24 in which the exit end of coin chute 15 can be moved from a rest position above the entry to coin validator 24 to a position above a return chute 25. The coin chute can then be separated into two pieces, causing lodged coins and foreign matter to fall out of the coin chute. In another aspect of the invention, foreign objects like coat hangers that are pushed into coin chute 15 are forced out of coin chute 15 by slots 30 which are formed on the back edge of coin chute 15. Coat hangers or other objects are thus prevented from going further into coin chute 15 and coin validator 24. The same objective is accomplished by a bevelled edge 29 formed on an edge of chute piece 23, one of the two pieces forming coin chute 15.
