Definitions

  • Patented Dec. 27, 1938 UNITED STATES PATENT OFFICE TELEPHONE MECHANISM Application June 6, 1936, Serial No. 83,883 In Switzerland June 8, 1935 scribed which may be incorporated with charge I registering mechanism adapted to register at the local station the charge or toll for particular calls, and to transfer the charges between successive calls to a total charge register.
  • the invention as to these features may be combined with a registering mechanism such as is shown and described in our copending application S. N. 46,229, filed Sept. 12, 1935, and in certain of its aspects the present invention may be regarded as an improvement upon the mechanism shown in our said copending application.
  • an electromagnet l (which may be the same as or similar to the electromagnet l in our copending application) is connected in circuit to receive timed current impulses from the exchange, or otherwise imposed. upon. the circuit to measure and register the time charge -for calls.
  • the electromagnet may be connected in circuit to receive the same current impulses as the charge register at the telephone exchange.
  • This electromagnet may be connected with the registering mechanism, in the manner shown and described in our said copending application, and the whole is enclosed within a sealed casing in a welldinown manner.
  • the electromagnet E has apivotally mounted, rotatable armature 2, rotatively mounted on a support 3, a spring 4 acting on the armature against the attraction of the field.
  • the armature 2 has connections to the registering mechanism to accumulate charges thereon, such as the pawl 5, ratchet wheel F2, and connected mechanism, shown in our copending application and omitted licrei'rom to" the sake of clearness. These connections may be direct to the armature, or they be operated shaft it, or otherwise. These connections to the registering mechanism are not interfered with by the mechanism of the Jresent invention. All the mechanism is usually enclosed in a sealed casing C.
  • Objects of the invention are to provide means controlling local telephone stations so as to permit calling other stations only under control and by permission of a supervisory authority, usually a person responsible for the making or the collecting of tolls or charges; to provide in a mechm of the kind described means operating automatically to prevent the making of succeeding calls from a local station, such as a pay station, without separate authorizations and releases by the supervising authority; to provide such means for blocking the making of successive and un authorised calls which begins operating automatically as soon as the station called on an authorized call responds and during the ensuing conversation, and prevents further calls until the mechanism is again released by the supervisory authority; to effect the foregoing objects relating to making calls from a local station without affecting or interfering with the use of the station for receiving calls; to provide means of the character described especially adapted for local stations having dial-operated station-selecting means, such as are connected to automatic exchanges; to provide meansof the character decalls being made, that is, the dial selection of other stations, while at the same time permitting
  • a supervisory authority may release the local telephone S for the making of a single call, and as soon as the connection is established, that is the called telephone answers, the mechanism automatically prevents the making of additional calls, or dial station selections, without notification to. and a new release by the supervisor.
  • a pin I8 is fixed to and extends from armature 2 near one end thereof.
  • An arm I9 is fixed on a shaft 20, and extends into the path of the pin I3, and when the armature 2 is rocked by the magnet I against the pull of the spring 4, the pin I8 rocks the arm I9 and the shaft 28.
  • Arm 24 Fixed on the shaft 20 is another arm 2I, having at its outer end a pin 22 which projects through, and fits loosely within, an elongated slot 23 in an arm 24.
  • Arm 24 is mounted to rock about a pivotal support 25, and is impelled in clockwise direction by the spring 25, and is rocked against its spring in counter-clockwise direction, as indicated by the arrow A, when magnet I rocks the armature 2.
  • a plate-like lever 30 is pivotally mounted at 3i and is impelled in counter-clockwise direction by a spring 32.
  • a detent notch 33 on lever 24 engages beneath one end of lever 30, in a certain position of the mechanism, to hold the lever against the pull of its spring 32.
  • lever 39 Fixed to and projecting from the other end of lever 39 is a pin 34 of insulating material, the pin 34 being in engagement with the outer end of the spring terminal I2 of the circuit II), II.
  • An indicating device 36 may be attached to the lever 35, and inscribed with a legend viewable through an opening in the casing.
  • the means for actuating the releasing mechanism, so as to permit calling of other stations comprises a spring-mounted pin M, which is under the control of a proper authority, for instance, a person in charge of the telephone station.
  • a lever arm 42 is pivotally mounted at 43, and has a contact plate 44 located in the path of the pin M, the lever being oppositely acted on by a spring 45.
  • a pin 46 Fixed to and projecting from the other end of the lever arm 42 is a pin 46, adapted to contact with the edge 41 of the lever 30, when arm 42 is actuated by the projection of the pin I, and as the pin 45 rides over the edge 41, lever 35 is rocked in a clockwise direction, and pin 34 bends spring contact I 2, opening the circuit I 0, I I and putting the impulse contact J of the dial mechanism in circuit so that a call can be made.
  • Connections are also preferably provided for transferring charges from the charge register to the total register, as by rocking shaft 51, in our copending application, from lever 42 of the present case, or otherwise.
  • Means are provided for releasing the mechanism independently of the precedingly described operating mechanism just described, as for instance when an authorized call is not completed, the making of a succeeding call may be prevented, if desired. At such time the mechanism is in the position of the drawing.
  • is provided, which may be actuable at the local station or from any central station.
  • the pin BI is mounted in the casing C, enclosing the entire mechanism, and may have an external operating button 53.
  • a contact plate 56 formed on a bent lever 57, pivoted at and acted on by spring 6
  • a pin 58 At the end of the other arm of lever 51 is a pin 58 which projects into the path of an arm 59 formed on the lever 24.
  • pin Si When pin Si is moved inwardly, it engages contact plate 56, rocks lever 51 against its spring GI, and pin 58 engages the arm 59 and rocks lever 24 in the counter-clockwise direction, releasing lever 30.
  • Spring 32 rocks lever 30 in counter-clockwise direction, and the circuit is closed at the spring contacts I2, I3, and the dial-selector J is shortcircuited until again released by the actuation of the pin M by the supervisory authority.
