Abstract
Abstract The system may use 48 volt battery reversal and is programmable or adaptive to all known systems. Closure of the paystation hookswitch (termed ''''off-hook'''') applies power of one polarity, (L1 negative) which is shunted around the motor during transmission, deposit of the coins, and dialing. Upon answer, the power is reversed and the motor operates sequentially to place the vane in a collection position first, and then, release the coin trap so that the escrow money is collected. At the moment of reversal (L1 negative becomes L1 positive), the magnetic flux field build-up around the motor coil effects the closing of a switching arrangement designed to shunt all other apparatus within the paystation, normally employed for transmission, coin annunciator, restoring relay and dial. An actuation circuit for an SCR shunting the motor coil but with the SCR oriented to allow current flow only when triggered and L1 positive so that triggering is made possible when both vane and coin trap sensing switches (in series to the SCR trigger) are closed, causing current to flow through the SCR causing the motor coil to be bypassed, and therefore de-energized. The now conducting SCR releases the shunt switching circuit to open and thereby remove the transmission and other equipment shunt to enable communication, while at the same time shunting the motor out of the circuit thereby eliminating associated insertion losses. Refund is effected by on-hook through a mechanical back-up failsafe connection, and refund control is accomplished by: (a) Mechanical linkage from the switchhook to the coin distributor device. (b) Manually operated electromechanical refund lever accessible to the station user. (c) Tone control causing the breaking of continuity of the motor shunting diode . . thereby allowing current to flow through the motor coil. (d) A negative L1 voltage exceeding 63 volts will be seen by the motor thereby effecting refund in either ''''on-hook'''' or ''''off-hook'''' condition. (e) Pulsing a delayed gate wherein the SCR gate turn on can be delayed to effect temporary flow through the motor for approximately one-tenth of a second after current turn off and on.
