Definitions

  • the invention relates especially to the provision of means whereby when the sender has finished sending a message an alarm will automatically be sounded until the main switch is moved to throw the transmitting instrument out of circuit.
  • FIG. 1 isabroken plan view of a transmitting instrument constructed in accordance with the invention.
  • Figs. 2 and 3 are detail Views, on an enlarged scale, showing one of the pen-arm supports and connections, looking in the direction of the arrows 2 and 3, respectively, of Fig. 1.
  • Fig. 4 is an enlarged detail showing the connections of the two pen-arms and pen.
  • Fig. 5 is a detail looking in the direction of the arrow 5 of Fig. 4.
  • Figs. 6 and 7 are detail views, taken on the line 6 7 of Fig. 4, showing the parts in different positions.
  • Fig. 8 is a diagrammatic view showing the alarm-circuit connections.
  • Fig. '9 is a view similar to Fig. 8, partly broken away and showing a modification.
  • A represents the writing-platen on which the paper rests; B, the hand or arm rest; O, the transmitting pen or pencil, and D and E the two pen-arms.
  • the adjacent ends of the pen-arms are connected together, and the pencil is connected thereto near its point by a swivel connection, and the pen-arms are connected to pendrums 10 by means of cords 11, passing around the pen-drums, and are supported by means of slotted guides 12, all as usual.
  • connection between the ends of the penarms is formed so that when the pen is in the position of rest a member carried by one arm will be in electrical contact with a member carried by the other arm; but when the pen is moved into writing position these two members will be moved out of contact with each other.
  • This result may be secured in any suitable manner, but, as shown, one of the arms E is provided with a non-conducting sleeve 15 and the arms are secured together by means of a strap 16 of conducting material carried by the other arm D and extending about the sleeve 15.
  • the strap 16 is provided with a lug or shoulder 17, in position to be engaged by a yoke 18, carried by the arm E, and which forms a part of the swivel connection between the arm E and the pen.
  • the lug 17 is so positioned that it will be engaged by the yoke 18, as shown in Fig. 7, when the pen is in the position of rest or lying on the arm-rest B, as shown in Fig. 1.
  • the yoke 18 will be turned away from the lug 17, as shown in Fig. 6, so as to break the electrical connection between them.
  • the strap 16 and yoke 18 are in electrical connection with the brackets 20, and this connection is preferably through the penarms D E, a good electrical connection between the pen-arms and the brackets being preferably secured by means of a pair of spring-rods 21, adapted to bear on either side of the pen-arm.
  • the complete alarm-circuit is as follows: starting from a local battery G, by wire a to a contact-plate b of the master-switch H, contact-spring 0, wire cl, to connecting-springs 21, then through the penarms E and D to the other connecting-springs 21, and thence by wire e through a buzzer I and back to the battery.
  • the contact-spring 0 When the master-switch is in transmitting position, the contact-spring 0 will be in contact with the plate I); but the circuit will be broken between the lug 17 and yoke 18 when the pen is in position for writing.
  • the pen is dropped to its position of rest, the lug 17 and yoke 18 will be brought into contact-and the alarm-circuit wil-lbe-completed, and-the alarm will consequently sound until the master-switch is moved to throw the transmitting instrument out of circuit, by which movement contact between the spring. 0 and contact b will be destroyed and the alarm-circuit opened.
  • What I claim is 1.
  • telautographic transmitting instrument havinga transmit -tingpen and pen-arms substantially as deting-pen and pen-arms substantially as described, and devices for connecting the ends of the pen-arms and the pen including two contact members which are in contact when the pen is in the position of rest and are not in 'contact'when 'the'pen is in the position for writing, and an alarm-circuit including said contact members, substantiallyas-described.
