ent invention.
Referring more particularly to the drawing, I have indicated at 1 an evacuated receptacle provided with the usual base portion 2 and a reentrant portion and stem 3. A cathode 4 is mounted in the tube and connected to a pair of leading-in wires 5 and 6 which extend through the stem 3. A control electrode or grid 7 surrounds the cathode 4: and is connected to aleading-in wire 8. A second rid 9, which may be used as a screening grid, surrounds grid 7 and is supported from a collar 10 which surrounds stem 3-. Grid 9 comprises a plurality of supporting wires 11 which carry at their outer ends a metal plate 11'. Short angular wires 12 are welded to the end portions of wires 11 and carry a pair of oppositely disposed, insulating glass rods or beads 13 at their outer ends. The anode or plate electrode 14 is also provided with short angular wires 15 which are welded to rods 16, the latter extending through radiating fins 17 on the anode mem- The novel features which I believe to .be characteristic of my invention are set forth with particularity in the appended claims. My invention itself, however, will best be understood from reference to the following specification when considered in connection with the accompanying drawing in which the single figure is a perspective view partly broken away of a vacuum tube or discharge device embodying the features of the pres- GOMPANY, A CORPORATION OF NEW YORK.
