Definitions

  • invention relates to the arrangement .of apparatus at a teleprinter station.
  • An object of the invention is to provide a teleprinter station arranged in such manner as to facilitate the performance of the various duties of the operator so that the time occupied by these duties is reduced.
  • a telegraph station comprises a tape teleprinter having a paper roll holder mounted in a readily removable manner in the rear of the machine and externally to the cover and having the printing point at one side of the machine and also external of the cover.
  • the paper may be fed through the machine without opening the cover and the time taken for this and for detachment of lengths 20f tape to be :afiixed'to telegraph forms is also considerably redmzed.
  • the ink ribbon mechanism is so mounted that the ink ribbon may be replaced Without opening the cover.
  • cover of the machine is preferably so constructed as to support trafiic trays.
  • Fig. l is a perspective view of a teleprinter combined with a keyboard transmitter such as may be used :torduplex operation, with the cover in position on the machine and with the arrangements for a teleprin'ter station according to the invention.
  • Fig. '2 is a view of the machine with the cover removed. 7
  • a teleprinter station comprises a receiving 'teleprinter generally denoted by the reference numeral l and a keyboard transmitter 2 driven from a common motor 3 in well 'known manner and mounted on a common base plate 4.
  • the keyboard 5 is placed at the front of the machine, and the station is arranged for duplex operation in well known manner.
  • the receiving teleprinter is constructed and operates generally in the manner described in British specification No. 228,842.
  • the typewheel 6 is, as described in that specification constructed with movable type, st-ruck against a tape 1 passing round a printing platen 8 by a printing hammer '9.
  • the type wheel :6 is located at the left hand side of the machine.
  • a supporting plate 1 t fora tape ro'll holder H is removably mounted in the left hand portion of the rear of the machine in the manner described and claimed in co-pending U. S. application No. 592,171, filed May 5, 1945, now abandoned.
  • the printing platen 8 is mounted on the exterior of a frame l2 hinged at l3 to the base 4.
  • the paper feeding mechanism and the spools M for feeding and reversing the feed of an ink ribbon I5 are mounted on the interior of frame l2 as described in co-pending U. S. application No. 589,247, filed April 19, 1945, now Patent 2,480,165, patented Aug. 30, 1949.
  • cover 16 is provided with two apertures, one for the keyboard 5 and another for the frame l2 and is shaped with a portion [1 fitting over the upper part of the typewheel.
  • cover [6 is over the machine there is left a small aperture under the portion ll through which the selected type on the typewheel may be struck against the ink ribbon l and paper tape 1.
  • ink ribbon spools can readily be changed by the operator when sitting at the front of the machine, since the frame I2 can be swung outwards on its hinge 13, whilst the supporting plate 10 can be grasped by the left hand of the operator and pulled out in order to replace a fresh roll of tape in the tape roll holder H.
  • the front portion 18 of the cover I6 is sloped to serve as a message desk, a support [5 for matter to be transmitted being fixed to th cover.
  • the top of the cover It is flat and is formed with short vertical sides 20 so that it serves to hold a trafiic tray 2
  • 'A further tray 22 may be supported by being hooked on to books 23 in the side of tray 2
  • the right hand compartment 24 may be Wider than the other compartments and assigned to outgoing traffic.
  • An inverted V-shaped strip member 25 carrying along its top edge a station indicator may fit into this compartment thus dividing it into three receptacles, which may be allocated as follows: right hand sloping side for new traffic to be transmitted, left hand sloping side for trafiic sorted into correct order of priority for transmission, flat bottomed space between the two sloping sides for trafiic that has been transmitted and is awaiting acknowledgment by the distant station.
  • This arrangement of message trays on the cover of the machine facilitates the handling of the trafiic in an expeditious manner.
  • the inverted V strip 25 When the station is closed the inverted V strip 25 may be turned on its side thus preventing telegrams being placed into the receptacles for outgoing traffic and giving an indication that the station is closed.
  • a teleprinter machine comprising, a plurality of individually movable type face bars mounted in a circular array to form a type wheel, means to support said wheel for rotation about a horizontal axis, a printing hammer for engaging a selected type face bar with which it is in alignment to reciprocate said bar in a horizontal direction, a motor and a motor-controlled selector mechanism for said type face bars for bringing a selected type face bar into operative alignment with said hammer, a cover member for said machine substantially completely enclosing said type wheel, said selector mechanism and said motor, said cover member having a small window disposed in a, substantially vertical plane adjacent the ends of said type face bars to permit a selected type face bar to protrude horizontally therethrough when struck by said hammer, and a printing platen external of said cover and mounted adjacent said opening for rotation around a vertical axis.
  • a teleprinter machine in which said printing hammer, said motor and said selecting mechanism are mounted on a frame entirely enclosed by said cover member, means for supporting a tape supply reel external to said cover, and means for supporting and feeding the tape from said reel between said opening and said platen, said tape being located entirely external to said cover.
  • a teleprinter machine in which said printing hammer, said motor and said selecting mechanism are mounted on a frame, said frame having hingedly mounted thereon a plate which serves to complete the closure of said cover, said plate carrying on its side facing the interior of the cover a pair of inked ribbon supply spools and means to guide the inked ribbon from said spools to a point externally of the cover and between said platen and said window.
  • a teleprinter machine in which there is attached to the rear of the machine a removable plate carrying a tape supply reel, and additional means are provided for guiding and feeding said tape to the printing point located between said platen and said window, said tape being entirely external to said casmg.
