Definitions

  • This invention relates to a method of mounting the electrode system for electric discharge to and fro till they engage in the corresponding apertures of the second centering membenwhereupon the latter member is slipped on the electrode extremities.
  • moving the extremities to and fro in order to make them engage in the said apertures takes much time and requires much routine whilst involving the danger of the supporting wires and electrodes being bent. More particularly the lower grid turns are in this case frequently damaged.
  • the said diificulty may'be somewhat reduced by providing that the extremities of the supporting wires are of different lengths to enable them to be introduced successively into the associated apertures, but in this case also the danger of damage of the electrodes is considerable, especially also on account of the fact that the electrodes, instead of being pinched at one extremity, are loose in the apertures of the first centering member.
  • the electrodes are thus unstable and may consequently contact with one another and be damaged.
  • the electrodes to be mounted are first placed with one extremity in the apertures of a centering member andclamped, for instance below that centering member by pinching means more fully described herein below.
  • the other electrode ends are aligned with the apertures of a second centering member in position to be introduced into said apertures. For the purpose of aligning these ends,
  • a centering jig which has two jaws cooperating with. each other .for holding said ends in place.
  • the upper extremities of the electrodes are pinched in position between toothed jaws of a centering jib, which is removed after .the extremities have been: in troduced into the corresponding apertures of the upper centering -mern-ber, whereupon the said member may be-slippedonthef electrode extremities.
  • the electrodes .are pinched also atthe lower-extremities, for example at the extremities,projectingabelow the lower centering member preferably, a short time beforethe toothed jaws engage the upper extremities.
  • Figure 1 shows an arrangement of an assembly jig according to the invention
  • Figure 2 shows a detail of such a jig.
  • reference numeral l designates a holder consisting of a thin plate which comprises a recess to accommodate the lower centering member 2, as a rule in the shape of a mica disc.
  • the holder l is secured to a stand 7.
  • lhe lower extremities of the electrodes 3 are introduced into the apertures of the member 2 and may be pinched in position at the portions projecting below member 2 by means of a pinching device.
  • the jaws 4 and 5 are closed whereby the upper extremities of the electrodes 3 are fixed in position; in a centered manner to enable them to be introducedwithout difficulty into the apertures of the upper centering member 6, whereafter the jewel and 5 are removed.
  • the member 6 is slipped on the electrode extremities and fixed in position in the usual manner.
  • each of the jaws 4 and 5 may be provided with a toothed edge, it generally suffices if one of the jaws exhibits a toothed edge and the other a straight one.
  • the electrode extremities projecting below the lower centering member may be pinched in position by means of a rubber pinch, but preferably by means of a pinching device of the type shown in the figures.
  • the stand 1 exhibits a plane portion 8, provided in such manner that, when it is engaged by the electrode extremities [4, the electrodes extend vertically through the apertures ofthe holder l and the centering member 2.
  • the electrode extremities I4 are immovably urged against the plane 8, the knife-edge ll slightly cutting into the extremities of the supporting wires.
  • the movement of the arm 8 is determined by the abutment l2 and is adjustable by means of an adjusting screw I3.
  • the electrodes are immovably held in position by the knife II also in the vertical direction so that the lower grid turns no longer run the risk of being damaged by pressure exerted on the upper extremities of the electrodes when the upper centering member is slipped thereon. Owing to the fact that the knife-edge ll cuts into the supporting wires M, the pinching operation cannot be affected by differences in the thickness of the supporting wires.
  • a method of assembling an electrode system for an electric discharge tube in two centering members having apertures for receiving the ends 4 of said electrodes comprising the steps of placing one end of each electrode in the apertures of one of said centering members, clamping and cutting into each' oi', the assembled ends of the electrodes to' iigidly'hold then'i against displacement in vertical and horizontal directions, aligning the other ends of said electrodes in position for entering the apertures of said other centering ,m'ember, temporarily clamping said other electrade endsto'hold them rigidly in said aligned position, and sliding said second centering member over said aligned other ends.
  • Adevice ror assembling an electrode system for an electric discharge tube in two centering members having apertures for receiving the ends of said electrodes, and a support for said first centering member, said support including clamping mea-ns for rigidly holding one of the ends of the electrodes against vertical and horizontal displacement, said clamping means comprising a plane-faced element and a knife-like element adapted to cut into the electrodes and rigidly clamp themagai nst the plane-faced member.
