VACUUM-TUBE-ELECTRODE ASSEMBLING JIG.
Application filed August 29, 1919. Serial No. 320,576.
To all whom it may concern:
Be it known that I, WALTER J. Lnvnmoon, a subject of the King of Great Britain, residing at Mount Vernon, in the county of Westchester, State of New York, have invented certain new and useful Improvements in Vacuum-Tube-Electrode Assembling J igs, of which the following is a full, clear, concise, and exact description.
This invention relates to an assembling jig for vacuum tube electrodes and has for an object the provision of a unitary structure that may be employed for holding and spacing the electrodes while they are being, fastened to their supporting stem which is to be sealed in the bulb of the vacuum tube.
This invention is particularly adapted to.
be employed in connection with vacuum tubes, the electrodes of which are supported from a vertical stem which arises from the glass squash or press in the lower portion of the tube. Since it is important that the electrodes of a vacuum tube be spaced accurately with respect to each other and aligned properly'with respect to the stem and squash of thetube, the assembling jig of this invention has been provided.
- This asembling jig comprises a main body member havin two pivoted side portions or plates which, by suitable spring means are adapted'to be held at times in parallel relation with each other. contain spaced grooves for the electrodes of such depth that when the plates are in the parallel relation with each other, the electrodes are held rigidly therebetween. Spacing members are also provided at both ends of the main body member for maintaining the jig in the desired relation with respect to the glass stem. The jig is supportingly fastened to the glass" squash by suitable spring means such as a spring clip between the arms of which the squash may be inserted.
This invention will be better understood by reference to the following detailed description taken in connection with the accompanying drawings in which Fig. 1 represents the preferred form of this invention; Fig. 2 represents the assembling jig supporting a plurality of electrodes which are to be fastened to an electrode support; Fig. 3 is a cross-sectional view of Fig. 2, taken through'the main body portion of the assembling jig; and Fig. 4 represents a. vacuum These side portions tube-having an electrode structure of the contains a plurality of parallel grooves 10,
11, 12 and 13 which are spaced with respect to each other according to the distance desired between the various parts of the electrode structure to be held by the jig. The inside face of plate 8 contains similar grooves 15, 16, 17 and 18. Plates 7 and 8 are adaptedto be held in parallel relation with respect to each other by means of a spring 20 which is mounted on the back face of the main body member 6. The depths of grooves 10 and 15 are such that'when the plates 7 and 8 are in parallel relation with each other, the plate electrode 21 is held tightly therebetween. Similarly grooves 13 and 18 are of such a depth that the plate electrode 23 when inserted in the groves, is held rigidly between the plates 7 and 8. In case it is desired to have less tension on the two parts 24 and 25 of the grid electrode than on the other electrodes supported by the jig, it may be necessary to provide pockets in thebottoms of grooves 16 and 17 in each of which a steel ball 27 may be placed. These balls f'ma be pressed tightly against the edges 0 the grid in grooves 16 and 17 by means of the two springs 30 and 31.
The assembling jig may be rigidly fastened to the squash of the stem on which the electrodes are to be mounted, by means of a spring clip 33. This spring clipalso serves to align the electrodes with respect to the squash. Pivoted to the upper end of the main body portion 6 is a spacing member 36 which determines the position of the jig with respect to the stem 32. Member 36 is shown slotted on accountof wires 37 which would otherwise interfere with the positioning of the member. The length of arm 36 should be such that when its .free end is in contact with stem 32, the electrodes held by the jig are spaced properly away from the stem. The thickness of arm 36 should be such that when it rests on the top edges of plates 21 and 23 and the two bars 39 and 410 of the grid, the electrodes are the proper distance away from the squash 29. 'A lower spacing arm 41 is also provided of such a two electrodes are spaced properly with respect to the lower end of the stem 32.
In case it is desired to have additional means besides the spring clip 33 for holding the jig to the stem, a resilient latch-plate 4 may be provided which may be pivoted to plate 8 and adapted to hook over the end of plate 7. Spring arms 45'and 46 of this plate serve to keep the ends of the spacing arms 36 and 41 in contact with stem 32. Plate 44 also aids spring 20 in keeping plates 7 and 8 pressed tightly against the electrodes.
After the plates .21. 23 and grid portions 24 and 25 have been spaced in the jig. the
Fig. 4 shows the electrode structure assembled in Fig. 2, embodied in a vacuum tube 50 of thewell-known audiontype.
