Abstract

264,943. Pearse, W., and Morris, E. E. Nov. 4, 1925. Coin action, with optional use of coins of different value with change-giving, and multiplecoin.-In a combined coin-freed delivery and change-giving mechanism, the coins of lower denomination inserted for effecting delivery of articles are diverted in succession to the different reservoirs of a plurality of coin reservoirs equal in number to the number of such coins, which may have to be given as change when the apparatus is freed by a coin of higher denomination than the value of an article. As applied to a ticketvending machine taking pennies, sixpences and shillings, the pennies b, Fig. 1, are diverted in succession to five reservoirs a<1> - - a<5> by four three-armed levers c. A penny entering the reservoir a<5> depresses the tail c<1> of the fourth lever and raises its flaps c to divert the next penny to the reservoir a<4>. This next penny tilts the third lever and by acting against an arm c<2> of the fourth. lever resets it. When a penny has entered the reservoir a<1> the next penny runs over the flaps c to reservoir a<3> and the sequence begins anew. When a penny drops into a reservoir it acts on a lever a causing arms d<1> to dip into mercury baths to complete an electric circuit for actuating a ticket-delivery mechanism of the kind described in Specification 226,360. When a sixpence is inserted in a separate slot it actuates the ticket-delivery mechanism and closes the circuit of a solenoid which displaces, against the action of a returning spring, a slide e to withdraw a penny from the bottom of each reservoir, as change. The sixpences pile in a tube f, Fig 2, so that, when a shilling is inserted, another slide g actuated by a solenoid g' withdraws a sixpence while the slide e is withdrawing five pennies. The machine can be set to give tickets at a price more than one penny and less than sixpence by blocking access to one or more of the reservoirs a<1> - - a<5> by wedge pieces such as j<1>, Fig. 1. Certain of the contacts d, d<1> are cut out and also some of the reservoirs are obstructed at the bottom by shutters inserted in slots k<1>. Coin-slit closing-devices.-When any of the reservoirs a<1> - - a<5> become empty, a. lug l<1>, Fig. 2, on a spring-pressed plunger l provided on the slide e opposite that reservoir, makes contact with a bar m and completes an electric circuit. Magnets are thereby energized and release a spring-controlled shutter to close the sixpenny insertion slot. Normally the plungers l encounter the superposed pennies which prevent the lugs l<1> from contacting with the bar m. A shutter for the shilling slot is similarly released when the sixpenny tube f becomes empty.
