Definitions

  • This invention relates to telegraphic receiving apparatus of the kind, known cornmercially as anundulator, comprising a s1- phon recorder carried by a polarized armature arranged vertically between the upper and lower pairs of poles of two vertically arranged electro-magnets the windings of which are traversed by the electric signals the nature of whichis to be recorded by the siphon recorder on an endw'ays movable tape, one end of'the siphon recorder dipping into a vertically adjustable ink receptacle.
  • the present invention has for its object to improve the construction and working of such telegraphic receiving apparatus and to enable adjustment of parts thereof to be made in a quick and effective manner to suit requirements.
  • the levers connected by springs to the armature and the adjusting screw associated therewith are carried by a. support that is cap-able of being adjusted laterally, as by a set screw, against the action of a spring.
  • Armature adjusting means of the kind described can be variously constructed.
  • Figs, 1 and 2 are elevations at'right angles to one another and Fig. 3 a plan, with parts removed, showing apparatus of the kind referred to embodying the present invention.
  • Fig. 4 is a horizontal section on the line IV-TV of Fig. 1.
  • a and B are the vertically arranged electro-magnets between the upper and lower pairs of poles A B and A B of which the vertically arranged polarized armature C is mounted oscillate about a-vertical axis in the usual way.
  • the armature adjusting means comprises, as hereinbefore stated, two levers a, b connected through coiled springs 0, c to a lever arm d fixed to the spindle e of the armature C.
  • the levers a and b in the example shown, consist of two flat bent arms arranged in the same horizontal'plane as the lever arm (Z and pivoted at a b to a laterally movable support f, their longer arms being connected to the springs c, c and their other and shorter arms a 6 extending towards one another and terminating near together.
  • the support f is carried by the upper end [L of an upwardly extendinglever arm h pivoted at k to a, lug 2 or extension carried by a base plate is, to which the pair of vertical electro-magnets A and B are fixed at their lower ends.
  • the lever arm h is connected by a spring a to'a pin n fixed to a vertical support 0 extending upward from the base plate 70, the said lever arm being adapted to be moved against the action of the spring by a set screw p extending through a bearing 29 carried by the said vertical support 0.
  • the receptacle 7' is the ink receptacle for the siphon recorder T which is fulcrumed, as usual, in a V shaped bearing e at the top of the armature spindle 6.
  • One end of the siphon r corder dips into the ink receptacle and the other end bears against a tape 1 which is supported by a platen 0 and is drawn forward by feed wheels 1", in the usual manner.
  • the receptacle which may be, of circular shape, as shown, is carried by a vertical rack 8 arranged to slide in a vertical groove 6 formed inthe said vertical support 0 and to be raised and lowered by a toothed pinion'u,
  • the spindle r is preferably journalled, as shown, in one of the side walls of the vertical groove t between the outer side of which and a knob 12 on the spindle o is interposed a spring washer w, or a. coiled spring, that normally holds the pinion it against the opposite side of the wall and in gear with the rack s.
  • the opposite wall of the groove if is formed with an aperture w through which the pinion a with its spindle Q) can be pushed, when assembling the parts for use.
  • y is a hood carried by the upwardly ext-ending lever h and covering part of the mechanism described.
  • the vertical support 0 may advantageously be cast, as shown, in one piece with the base plate 72 which, as usual, is adapted to be pivoted at one end at to a table or other.
  • the tape feeding mechanism which. is or may be of known kind, may be driven as usual heretofore, from an electric or other motor through mechanism of the friction type comprising a friction disc against which revolves a friction .wheel adapted to be moved across the face of the wheel to obtain a variable speed.
