Definitions

  • the invention relates to an automatic tele phone paystation in which the subscriber at the paystation hasan impulse sender or calling device by means of which a switching arrangement in the exchange is operated to extend a. talking circuit and which also determines the toll to be charged for the connection and sends back impulses to the paystation for automatic collection of the corresponding toll, switching operations being effected in the telephone paystation corresponding to the charge for the connection.
  • Respecting telephone paystations it is known to include a coin chute or receptacle to hold a plurality of deposited coins and a magnet controlled by impulses from the exchange by means of Which single coins are removed at particular time intervals from said receptacle in which they have been inserted by the talking party at the beginning of the conversation.
  • a coin chute or receptacle to hold a plurality of deposited coins
  • a magnet controlled by impulses from the exchange by means of Which single coins are removed at particular time intervals from said receptacle in which they have been inserted by the talking party at the beginning of the conversation.
  • the time interval between successive operations of the magnet can be varied according to the rate of charge for the connection.
  • the magnet should be operated a number of times in succession according to the charge for the connection whereby a coin is transferred from the first coin receptacle to the cash box each time the magnet is energised and further conversation prevented should the number of coins transferred be smaller than the number of impulses transmitted. Since in such systems the coins transferred are immedi ately collected, the calling party loses his money when the amount inserted is not sufficient to meet the toll.
  • United States Patent No. 1,480,403, granted January 8, 1924 and also the general structure of telephone paystations is shown in United States Patent No. 1,043,219, granted November 5, 1912, and in United States Patent No. 917,742, granted April 6, 1909.
  • Figure 1 represents diagrammatically th mechanical arrangement in the telephone paystation.
  • Figure 2 is a view of the coin channel which serves as the first receptacle.
  • Figure 3 shows a circuit arrangement of the telephone paystation in connection with the exchange apparatus.
  • Figs. 1 and 2 show a coin chute I in which the coins are first deposited by the subscriber, an intermediate receptacle 8 to which the coins are transferred one at a time from receptacle I, and a magnet ZM for transferring the coins.
  • the magnet ZM is mounted near the base of chute I, having the usual heel piece 2a supporting the armature 2 pivoted in the usual manner at 4 on the end of the magnet heel piece and carrying a lever 3 by means of which the coins are transferred.
  • a spring for maintaining the armature 2 in retracted positions.
  • the springs Zm are normally out of contact and caused to make contact when magnet ZM is energized.
  • the switch hook I3 is mounted rigid with a pivoted arm I5 at pivot point l3a so that when the receiver hook I3 is raised by spring l3b, upon embodiment of the invenremoval of the receiver (not shown), the upper end I51) of arm I5 acts as a closure for the lower end of coin chute I as shown.
  • a chute I6 is provided below this opening I5a to guide the released coins into the usual refund chute I4.
  • a platform 9 is provided at the lower side of intermediate receptacle 8 on which the coins fall when transferred thereto.
  • a collect magnet KM is provided below this platform and is arranged to tilt the platform about its pivot point I I, when the magnet is energized, to cause the transferred coins to be dumped from receptacle 8 into the coin box via chute I2.
  • the platform 9 is also tilted in the opposite direction about its pivot point I when the receiver (not shown) is placed on the hook to cause the coins in receptacle 8 to be refunded via chute I4. This operation is caused by the switch hook moving the lower end of arm I to the right about pivot Ita to lower the right side of platform 9.
  • circuit arrangement of Fig. 3 is only shown as one method of operating the transfer magnet ZM and the collect magnet KM and is of known type it being understood that any similar circuit arrangement could be-utilized.
  • This figure shows the paystation above the dotted line in the upper a corresponding number of times.
  • a repeater K in the central part thereof and indicates diagrammatically an equipment ZZZ in the exchange for sending back charging impulses.
  • the equipment ZZZ may be of any desired type similar to that shown in Patent 1,480,403 wherein impulses are returned to a calling line varying in number in accordance with the charge for extending a particular connection.
  • the subscriber at a paystation Prior to the extension of a connection the subscriber at a paystation lifts his receiver (not shown) and deposits as many coins as he believes will be sufficient for the connection which he intends to extend and these coins are held in receptacle I (Fig. 1) as described.
  • the lifting of the receiver from hook I3 operates the usual hook switch springs EU to complete the line circuit and energize the usual line relays A and B in the repeater K which feed battery to the paystation.
  • the circuit of relays A and B extends from ground through battery, relay A, springs I-IU, sender springs nsi, transmitter Mi, induction coil winding, springs Ir, springs 22, springs Id, and relay B to ground.
  • Relay A closes springs 2a in the line circuit, closes springs Ia to prepare a circuit for a second winding of relay A, and relay B closes the circuit of slow acting relay V at springs b.
  • the subscriber now operates the usual impulse sender or calling device which opens its springs mi in the line circuit to thereby control line relays A and B to repeat impulses via contacts 2a of relay A to the selecting devices in the exchange (not shown) to extend the connection.
  • the rectifier GL is so poled that a current from this circuit passes freely through it and it thus acts as a short circuit for collect magnet KM so that said magnet is not energized at this time.
  • the magnet ZM is thus energized to transfer a coin from chute I to receptacle 8 as shown in Fig. 1.
  • contacts Iz were first closed, relay I operated and closed its contacts II, H and II and opened its contacts 31.
  • Contacts 21 complete a circuit for slow relay D which operates and operates its contacts Id.
  • contacts Iz restore to the position shown, although relay I still has its circuit closed through contacts II, the contacts 4I are also closed and when the back contacts I a close the relay I is short circuited from ground over contacts Ia and AI and the relay I falls back.
  • Contacts ZI of relay I are therefore opened and contacts 31 are closed.
  • Contacts 2I open the circuit of relay D which is slow to release and before it releases a circuit is completed momentarily from any 50 cycle alternating current source as indicated through resistance Wi, contacts 3i, contacts Id, contacts 22, contacts Ir, through magnet ZM and condenser F in parallel, and magnet KM and rectifier GL in parallel to ground.
  • Magnet ZM is short circuited in this circuit to alternating current by the condenser F.
  • the cash magnet KM is energised by this alternating current and, as explained in connection with Fig. 1, transfers the money in the receptacle 8 to the coin box.
  • relay R associated with the paystation which is energized over a circuit from ground through the contacts em and the rest contacts m through relay R, contacts HU, and relay A to battery.
  • relay R When relay R is energized the relay B is disconnected by contacts Ir opening the original line circuit While the relay A holds over the above circuit through relay R.
  • the slow relay V which was energized by contacts b of relay B when the line circuit was first closed and which does not restore during the impulse transmission when'the circuit of relay B is opened by contacts nsi now deenergizes and connects an indicating signal (not shown) over contacts V and contact la to a second winding AII of the relay A.
  • a coin chute for holding deposited coins, means for extending a connection therefrom and for transmitting toll assessing impulses thereto, a receptacle therein for receiving coins transferred from said chute, means operated responsive to the impulses received at the paystation for transferring deposited coins from said chute to said receptacle to assess toll for the connection, means for collecting the transferred coins in case the number of coins transferred is equal to the number of assessing impulses received, and means for preventing the operation of said last means in case there are more assessing impulses received than there are coins deposited.
  • a telephone paystation such as claimed in claim 1 wherein the means for preventing comprises a relay for opening the circuit of said collecting means, a circuit for said relay and contacts in the circuit of said relay operated each time a coin is transferred.
  • a coin chute containing a plurality of deposited coins, means operated intermittently for moving said coins one at a time from said chute into a receptacle, a collect magnet for collecting the coins from the receptacle, a relay for preventing operation of said magnet, said relay only operated when said first means is operated a greater number of times than the number of coins deposited.
  • a coin chute carrying deposited coins, a receptacle, a transfer magnet, means for transmitting toll assessing impulses to said magnet to operate it to transfer the coins one at a time to said receptacle, a collect magnet operated at times to collect the coins transferred to said receptacle, a relay for preventing operation of said collect magnet, a circult for said relay, contacts controlled by each operation of the transfer magnet in said circuit, and contacts controlled by each coin when transferred, and means for refunding the transferred coins in case said relay is operated.
  • a telephone paystation having means for extending connections therefrom, a supply of deposited coins, an intermediate receptacle, a magnet, means for transmitting toll assessing impulses to said magnet to operate it for transferring deposited coins one at a time from the supply to said receptacle, a collect magnet, a circuit for the collect magnet completed after the toll assessing impulses are received, a relay for opening said circuit, contacts controlled by said transferring magnet for closing a point in said circuit each time the transfer magnet is energized, other contacts in said circuit opened each time a coin is transferred to said receptacle,
