Definitions

  • the present invention relates to a dial-operated telephone adapted to be rendered inoperative when certain numbers are called and in order to block certain calling numbers, a device is coupled A p to the impulse dial which, after inserting a coin and on setting one of the blocked numbers, shortcircuits the impulse contacts.
  • the apparatus is also arranged so that the calling of certain numbers may be eiiected without insertinga coin.
  • Thetelephone apparatus is provided with con;- tacts which can be blocked to render the above mentioned device withoutflefiect and to change the apparatus into an ordinary telephone, that is one for establishing connections without the insertion of a coin.
  • the apparatus is further provided with. devices which break the connections in the case of improper manipulations or insuflicient payment, and eject the coin to show the, person using the apparatus that he hasnot o handled it correctly.
  • the current enteringlthe apparatus at the terminal a passes successively through the contacts Kl associated with the impulse disk U, through the conductor c to the terminal (1 and through the Wire e and the primary of the transformer Tn
  • the current then passes through the microphone M2, the contacts K2 and the switch indicatedat Kg. operably associated with the receiver hook Ga. and leaves. the apparatus at the terminal 22.
  • the coin balance includes a beam W pivotally mounted at O1 and provided with a counter- Weight Ge.
  • the end of the beam opposite the counterweight is provided with a cup GS for receiving a coin and the beam is provided with an arm H adjacent the pivot 06.
  • a push button D is provided for actuating a wedge-shaped member Sic which is maintained in an elevated position by means of a spring engaging the buttonD.
  • a money box Ka serves for receiving the coins when a call has been completed through the apparatus.
  • a coin inserted in. the apparatus first passes through a magnetic coin tester which includes a graduated slot E and a coin chute Mu having magnets S and N associated therewith.
  • the coin tester is provided for the purpose of preventing counterfeit coins or slugs from entering the apparatus.
  • Counterfeit coins or slugs made of brass are ejected in the direction of the arrow B because such coins are not attracted by the magnet S.
  • Coins formed of iron move in the chute Maas a result of. the magnetic attraction of the magnet S- and an iron coin will drop and move inthe direction of the arrow F as a result of the deflection created by the magnet N.
  • a genuine coin of the proper dimension will pass downwardly through the chute Ma and move therefrom in the direction of the arrow L intothe cup GS.
  • the weight of the coin in the. cup GS moves the beam W downwardly to the position indicated atII.
  • the coin is preventedfrom rolling out of the cup GS in this position of thebeam by means of. a plate P carried by a lever He.
  • the lever He is pivotally mounted at O2 and held in the position illustrated in full lines by means of a detent carried by the armature of the relay R. If the relay is energized the armature is attracted and thelever He is released and the end thereof carrying the plate P drops to the position indicated at P. If the lever He should move to the position P .the coin carried in the cup GS and held in the position indicated at II would roll from the cup through the chute A.
  • the switch represented at Kg is of a mercury type and is operatedby movements of the receiver hook Ga.
  • the switch Kg When the receiver (not illustrated) is suspended on the hook Ga the switch Kg is open and when the receiver is removed from the hook Ga the spring Fe closes the switch Kg.
  • the switches K4, K5 and K5 are operated by disks Schi, SchZ and Sch3 which are provided with peripheral projections. These disks are coupled with the impulse disk by means of a shaft W2. Thus the position of the disks carrying the peripheral projections are moved and the positions thereof are determined by the number called.
  • the disks Sohi and S0713 and the driving means thereof constitute the subject-matter of an application filed August 18, .1937, Serial No. 159,790 and the driving arrangement is not the invention herein claimed and these elements are disclosed only for the purpose of completing'the present invention.
  • the disks Schll and SchZ are turned when the first digit of a number has been dialed at the same angle as that of the impulse dial U and remain in this position until the end of the conversation.
  • the selection of further digits of the called number do not further influence the disks Schl and SchZ.
  • the disk S0113 rotates only when the second digit of the called number is dialed and this disk moves through the same angle as that of the impulse dial U and remains in that position. If further disks are required they may be similarly arranged to successively receive a setting by'other digits of the called number.
  • the projections carried by the disks are so arranged that one or more of the switches K4 or K5 or K6 will be closed upon a certain setting of the disks whereby one or the other of the blocking circuits is closed as hereinafter'more fully described and such a function will always take place when the call number does not represent a free call.
  • the number of teeth carried by the starwheel StR and the closing of'the switch K8 depends on the number of digits of the numbers to be called which are required for establishing connections to difierent exchanges. numbers to be called include four digits the'starwheel StR is provided with five teeth and when the number to be called includes five digits the starwheel will be provided with seven teeth and so on. Every further turn ofv the impulse dial after the dialingv of a calling number turns the starwheel StR by a further tooth and causes the closing of the switch K8 and the short circuiting of the impulse dial contacts Ki whereby all further impulses thereof are prevented.
  • every charge unit requires a sepa- When the rate combination of'disks and switches. Every combination requires as many single disks as there are digits of the called numbers. These digits are often referred to as characteristics and only the first one, two or three digits of a telephone number are characteristics even though the number itself may have four to six digits. Thus all telephone numbers of a town with 20,000 subscribers at the highest are within the range of numbers 20,000 to 39,999. Thus all numbers which present as first digits a digit 2 or 3 belong to subscribers of the same town and may be made accessible bypayment of the same charge.
  • each setof disks are connected in parallel and constitute together one blocking circuit.
  • the number of blocking circuits is determined by the number of the diiferent charges. Every blocking disk then becomes effective unless the amount provided for it has been inserted in the apparatus which must correspond to the proper charge. digits outside of this zone.
  • the apparatus functions in the following manner.
  • the receiver is lifted from the hook Ga the connection to the exchange is established.
  • a genuine coin is then inserted in the slot E. This coin passes the coin tester and drops into the cup GS and moves the beam W from the position I to,
  • the disk SchZ has a projection at 3 so that theswitch K5 will be closed which however is without effect, because the contacts K! have al-
  • the disk then blocks all v 2,206,147 ready been opened by the coin.
  • the digit 3 therefore will be transmitted to the exchange by three openings of the impulse contacts KI caused by the return of the impulse dial.
  • the disk Sch3 with the -projection I will close the switch K6 but the-circuit through the relay R will not. be completed beand the called person cannot hear the calling person. Therefore the calling; person must press the button D whereby the coin will be cashed.
  • a third operating sequence is possible and if a genuine coin is inserted in the slot E and a digit is chosen outside of the above described example such as a number beginning with 5, such a setting on the impulse dial U moves the projection 5 of disk Sch-l overthe finger of the switch K4 andcloses the same. Now the shunt circuit con-1 heated in parallel with thelcontacts Kl is closed. The five interruptions of the contacts Kl compel the current to pass through the relay R by impulses. The relay will thusrelease the lever He and the contacts K2 are thereby opened. The line is interrupted and the coin rolls from cup GS through thechute A to the outside of the apparatus since the plate P drops to the position P when the lever He is released. Thus the,
