Abstract

A coin chute adapted to receive interchangeable coin slides. One type of slide may have one or more coin sockets fitted with one or more knock-out plugs to accommodate differently sized coins in each of the sockets. Another type of slide has either one, two, three or four open coin sockets of different sizes. The chute carries a blocking device with a plurality of sizing dogs biased against the coin slide. The sizing dogs are adapted to engage with the coin receiving sockets of the slide to jam continued projected movement of the slide in the absence of predetermined sized coins therein. The position of the dogs relative to the sockets of the slide and the spacing between the dogs is pre-set to similarly engage with differently sized socket openings of replacement slides without further adjustment of the sizing dogs to permit interchangeable use of coin slides whereby the coin chute is operable to accept a variety of differently sized coins and coin combinations by changing slides.

Claims9

Dependent claims

In a coin chute device wherein there is, in combination, a lower assembly portion;

an upper assembly portion releasably connected to said lower portion and defining therewith a longitudinal guide track passage;
and a coin slide having first and second coin sockets to carry predetermined sized coins;
said guide passage being operable to receive said coin slide for reciprocal movement between projected and retracted positions therein;
and blocking means mounted on said chute to block movement of said slide in the absence of the predetermined sized coins in said sockets;
the improvement comprising:
said first coin socket defining a first path upon reciprocal movement of said coin slide;
said second coin socket defining a second path upon reciprocal movement of said coin slide;
said second coin socket being larger than said first coin socket;
and
said first socket being so located with respect to said second socket as to define said first path within said second path;
said blocking means including;
a first sizing dog biased against said coin slide and disposed along said first path, said first sizing dog being operable, in the absence of a first sized coin or other filler in said first socket, to project into said first coin socket to jam said coin slide;
and
a second sizing dog biased against said coin slide and disposed along said second path, said second sizing dog being operable, in the absence of a second predetermined sized coin or other filler in said second socket, to project into said second socket to jam said coin slide
to permit interchangeable use of coin slides having said first socket or said second socket without requiring adjustment of said sizing dogs for their operation.

In a coin chute device wherein there is, in combination, a lower assembly portion;

an upper assembly portion releasably connected to said lower portion and defining therewith a longitudinal guide track passage;
and a coin slide having sockets to carry predetermined sized coins;
said guide passage being operable to receive said coin slide;
said coin slide being disposed for reciprocal movement between projected and retracted positions in said guide passage;
and blocking means mounted on said chute to block movement of the slide in the absence of the predetermined sized coins in the sockets;
the improvement comprising:
said blocking means including;
a first sizing dog biased against the coin slide and disposed along a first path defined by the movement of an edge portion of a first predetermined sized coin carried in a first predetermined sized coin socket when the coin slide is reciprocally moved, whereby the absence of a first sized coin or other filler along said first path in the socket will permit said first sizing dog to project into the first predetermined sized coin socket to operate to jam said coin slide;
and
a second sizing dog biased against the coin slide and disposed along a second path defined by the movement of an edge portion of a second predetermined sized coin larger than said first coin carried in a second predetermined sized coin socket larger than said first socket and including said first socket within its extent when the coin slide is reciprocally moved, whereby the absence of a second predetermined sized coin or other filler in the socket along said second path, will permit said second sizing dog to project into the second socket to operate to jam said coin slide;
to permit interchangeable use of coin slides with either said first socket or said second socket, in conjunction with said coin chute, without requiring adjustment of said sizing dogs for their operation;
said coin slide comprising:
a first knock-out plug;
and
a second knock-out plug, said second plug forming a ring about said first plug;
the removal of said first plug forming said first socket and the removal of said second plug forming said second socket, whereby the coin to be carried in said coin slide can be predetermined.
