Definitions

  • This invention relates to coin collectors for use at telephone pay stations and more particularly to an electro magnetic coin handling and switching mechanism therefor.
  • a coin or token is deposited by the customer.
  • the coin in its passage operates certain mechanisms which cause the operation of a switch which completes a circuit to the central office to operate a signal thereat to indicate that communication is desired.
  • the mechanism includes an electromagnet which may be operated in one direction to collect the deposited coin and in the other direction to return the coin to the refund compartment.
  • the operating circuit for this electromagnet includes the switch contacts which are closed when the coin is deposited.
  • the present invention has as its principal object the simplification of the operating mechanism used in coin collectors of the prepay type and to insure their reliability and contemplates the use of a single electromagnet having associated therewith an armature operatively connected to a selector card and a cam member operated thereby.
  • the selector card is slidably and pivotally mounted and is constructed of insulating material, preferably nylon.
  • a permanent magnet Imbedded in the upper edge of the selector card and extending substantially the full width thereof, is a permanent magnet.
  • This permanent magnet is in spaced relation with respect to a pair of pole pieces which extend from the core of the electromagnet.
  • the selector card will thus tilt either to the right or to the left depending upon the direction of the current flow through the electromagnet, and at the same time will move downwardly under the influence of an operating bar and lug connected to the armature.
  • This combined action causes the cam member, operatively connected to the selector card, and also to a coin diverting vane, to operate the vane either to collect or refund the coin depending upon the'direction of the current flow through the electromagnet which is under the control of the operator at the central office.
  • Fig. 1 is a view in perspective illustrating the general form of the improved coin collector mechanism of our 2,951,635 Patented Sept. 6, 1960 taken on line 33 of Fig. 6 illustrating the selector card and its associated cam in their normal positions;
  • Fig. 3B is a view similar to Fig. 3A, but illustrates the selector card and the cam in the positions they assume when operated to collect;
  • Fig. 3C is a view similar to Fig. 3B, but illustrates the selector card and cam in the refund position;
  • Fig. 4 is a fragmentary side elevational view of the mechanism with its operating components in normal POSI- tion;
  • Fig. 5 is a view similar to Fig. 4 but shows the upper hinged shelf member or gate operated by the passage of coins, with the coins resting on the lower gate and the contact springs, which control the circuit to the central office, closed; and
  • Fig. 6 is a view similar to Fig. 5 but illustrates the upper gate restored to its normal position and the lower gate operated with the coins being directed to their proper channel by the vane which is controlled by the selector card through the cam.
  • an electromagnetic device comprising a single electromagnetic coil 10 which is supported on an E-shaped core 11 with the coil positioned over the center leg 12 between the outer legs 13 and 14.
  • a yoke member 15 as shown in Fig. 2 is secured to the rear side of the core 11 and serves tosupport the assembly by being secured to the arms 16 which extend from the coin chute casting 17, by means of screws 18.
  • a spring 27 is provided,one end of which is secured to the yoke 25 and the other to an extending ear 28, which forms part of the core 11.
  • ear 26 Associated with the armature 19 and adapted for movement therewith, is the ear 26 on the yoke member 25 heretofore referred to.
  • the free end of the ear 26 is positioned in an enlarged aperture 29 in the selector card 30 as shown in the various figures and with particular reference to Figs. 3A, 3B and 3C, and is thus operatively connected thereto as shown in more detail in Fig. 2.
  • the selector card 30 which is preferably constructed from an insulating material such as nylon, is slidably and pivotally mounted adjacent the downwardly extending ear portion 31 of the yoke 15, and has operatively associated therewith a cam member 32.
  • the cam 32 is pivotally mounted on the stud 33, parallel with and in spaced reltion with repeat to the card 30 and is adapted to tilt either to the right or the left as shown in Figs. 3B and 30 by virtue of the protuberance 34 and the teeth 35-35a.
  • Pole pieces 37 and 38 are of the same polarity with respect to one another but reverse their polarity with change in direction of current flow through the electromagnet.
  • the direction of current flow through the electromagnet is under thecontrol of the central office operator either to collect or refund a coin or coins.
  • the tilting of the card 30 to the right or left causes the card to assume a position with respect to the cam 32 and with respect to the protuberance 34 and the teeth 35-35a on said cam so that the downward travel of the card 30 under the influence of the ear 26 on the yoke 25, as shown, will cause one or the other of the teeth 3535a to be struck by the corresponding one of the teeth 54 or 53 on card 30 respectively.
  • the rotationof cam 32 due to the engagement of these teeth causes the protuberance 34 to engage and slide over the hump 39 in the apertured portion of the card 30 and come to rest either against the portion 40 or 41 thereof.
  • the direction in which the card 30 is tilted for example in Fig.
  • a coin chute casting 17 Pivotally mounted on the bracket member 44 and extending into the choin chute 17 at its upper end, as shown in Figs. 2, 4, 5, and 6, is a gate member 45.
  • This gate is so biased that the weight of a coin will cause it to tilt and to remain tilted until it is restored to normal by the operation of the armature 19, which upon being actuated, causes the ear 20 thereon to strike the slidable member 46, associated with the contact springs SP, which extends through the plate 47 of nonmagnetic material, secured to the core 11 and which controls the circuitry of the mechanism for collecting or refunding coins, completing a call or transmitting signals to the central office operator.
  • Latch member 52 then rotates under downward pressure of card 30 on ear 51 and strikes cam 55 on gate 48 to produce rapid movement of gate 48 to the open position. 'When the coins are released from the gate 48, as shown in'Fig. 6, the path they will take is determined by the vane 49 which is pivotally mounted in the coin chute 17 and diverts the coins either to the coin box for collection or to the refund receptacle.
  • the operation of the gate 48 and the vane 49 is controlled by the actuation of the relay RL and its associated parts, the vane tilting in one direction or the other depending upon the direction of the current flow through the electromagnet which causes the card 30 to tilt to the right or left and move downwardly and cause the cam 32 tomove to the right or left and carry with it the arm 42 secured to the vane 49.
  • a suitable terminal block TB is provided for establishing electrical connections to the contact springs SP and the coil '10 of the electromagnet.
  • a coin collector for telephone pay stations, an electromagnet, an armature therefor, a yoke member extending from said armature and having an apertured selector card operatively connected thereto, an apertured cam member in operative engagement therewith and having protuberances thereon extending into one of the apertures .of said card, a pair of spaced apart pole pieces extending from the core of said electromagnet and having their end portions in spaced relation with respect to the upper edge of said card, a permanent magnet imbedded in said card adjacent said upper edge and adapted to be influenced by the direction of the current flowing through said electromagnet and the resulting polarity of said pole pieces to selectively tilt said card either to the right or to the left and move it downwardly under the influence of said yoke member thereby causing said cam to swing in a clockwise or counterclockwise direction, a coin chute for the reception of coins in juxtaposition with respect to said electromagnet, a coin deflecting gate piv- .Otally mounted in said chute and
  • an electromagnet for telephone pay stations, an electromagnet, an armature therefor, a spring-biased yoke member extending from said armature and having a slidable and rotatable apertured selector card operatively connected thereto, an apertured cam member in operative engagement therewith and having protuberances thereon extending into one of the apertures of said card, a pair of spaced apart pole pieces extending from the core of said electromagnet and having their end portions in spaced relation with respect to the upper edge of said card, a permanent magnet, imbedded in said card, adjacent the upper edge thereof and adapted to be influenced by the direction of the current flowing through said electromagnet and the resulting polarity of said pole pieces to selectively tilt said card either to the right or to the left and move it downwardly under the influence of said yoke, thereby causing said camto swing either in a clockwise or counterclockwise direction, a coin chute for the reception of coins in juxtaposition with respect to said electromagnet, a coin de
