H. D. ARNOLDV- VACUUM TUBE Original Filed Nov. 2, 1915 V' HM/ llllllllll ll ing Patented June 9, 1931 UNITED STATES PATENT OFFICE HAROLD D. ARNOLD, OF MAPLEWOCD, NEW JERSEY, {KSSIGNOB TO WESTERN ELECTRIC COMPANY, INCORPORATED, OF NEW.YOBK, N. Y.,
A CORPORATION OF NEW YORK VACUUM TUBE Original application filed November 2, 1915, Serial No. 59,210. Divided and this application filed February 8, 1919. Serial No. 274,751.
The invention relates to electron discharge devices such as may be employed for repeaters, amplifiers, detectors, etc.
of a pair of inverted U-shaped end frames connected at top and bottom by relatively heavy wires and at intermediate oints on the depending portions by relative y fine wires forming the grid surfaces. The 'd surfaces are inter osed between thecat ode and the correspon ing anode surfaces. All of the electrodes are supported in position on the press or squash by means of a laterally disposed glass arbor.
This application is a division of application Serial No. 59,210, filed November 2, 1915.
The invention will be explained in the following detailed description and claims taken in connection with the accompanying drawwhich shows in perspective, partly brolien away, a vacuum tube embodying the invention. I
The vacuum tube 10 has sealed into its base a press 11 in which are sealed the leading-in wires for the electrodes. Extending .laterally and then upwardly from the press is a glass rod or arbor 12. The filamentary cathode 13 is supported at its upper end from the arbor 12 by means of wires 14, and at its lower end is connected to its external circuit b means of wires 15, its midepoint being furt or supported from the press by wire 16. The grid electrode indicated at 17 com rises the inverted U-shaped' frames 18 whic are rigidly connected at their u per and lower ends by wires 19. The depen ing side fr 05 These discharge devices commonly employ thus formed have connected thereacr oss the wires '20 which as shown are smaller than the wires forming the frames 18. The grid 17 is supported at its upper end from the arbor 12 electric signals (not shown) is receivedthrough a transformei'27, and the output'of the repeater is trans itted through a transformer 28. The secolili lary of the input transformer is shunted by a high resistance 29. Certain features of the repeater circuit shown herein are described and claimed in my Patent No. 1,448,550 of March 13, 1923.
It is to be understood that while the preferred embodiment of the invention has been illustrated, the invention is not limited to the exact form shown but includes variations thereof within the scope of the appended claims.
What is claimed is:
1. A vacuum tube device comprising an arbor, a Cathode, anode surfaces on op osite sidesofsaid cathode and a unitary ouble grid electrode having a plurality of substantiall parallel grid-surf aces, each of which lies between sald cathode and one of said anode surfaces, a rigid-metallic member connecting said anode surfaces, and supportin connections from said arbor to each of sai electrodes.
2. A gridelectrode for vacuum tubes comprising two U-shaped frames and a lurality of members connected at spaced mtervals therebetween. 7
3. A grid electrode for vacuum tubes comprising two U-shaped frames and a lurality of members connected at spaced intervals therebetween, certain of said members be ing smaller in cross-section than the members composing said frames.
4. A grid electrode for vacuum tubes comprising two U-shaped frames connected at single arbor substantially coextensive with said .electrodes carried by said column,- all of said electrodes being supported from said arbor.
7 A vacuum tube device comprising a neck, a double anode, a double grid electrode withm said anode, a cathode within said grid electrode, a single arbor substantially coextensive with said electrodes extending from said neck, and connections whereby said electrodes are supported solely by said neck and arbor.
8.A vacuum .tube comprising a plate, a second plate in parallel relation tosaid first plate, a supporting connection from said first plate to said second plate, parallel grid elements between said plates, a cathode between said grid elements, a single vertical arbor substantially coextensive with said electrodes, and supporting connections from said arbor to said electrodes.-
9. A vacuum tube device comprising a press, an M-shaped filamentary cathode, an
:arbor substantially coextensive with said cathode extending from said press supporting wires extendm from said press to the base of said cathode, supporting wires extending from said arbor to said cathode, and means for passing current serially through said cathode.
10. A vacuum tube device comprising a glass arbor, an M-shaped filamentary cathode extending in a plane parallel to and outside of said arbor, said filament being substantially coextensive with said arbor and supported thereby, and. means for passing current serially through said cathode. A
11. A vacuum tube device comprising a glass arbor, an M-shaped filamentary cathode extending in a plane parallel to and outside of said arbor, said cathode being substantially coextensive with said arbor and supported thereby, and another electrode supported from said arbor.
12. A grid electrode for vacuum tubes comprising twoU-shapedframes and a member of conductive material connected from one frame to the other.
13. A grid electrode for vacuum tubes comprising two U-shaped frames and a l-urality of parallel members connecting said frames.
14. In combination, a pair of parallel plate anode members, and a nd electrode comprising a air of U-shape frames disposed adjacent t e edges of said plates and at right angles thereto, and a member connecting saidv U-shaped frames.
electrode having a plurality of substantially parallel grid surfaces, a pair of frames, oneon each side of said cathode and each supporting one of said grid surfaces and a support for suspending said cathode between said frames.
In witness whereof I hereunto subscribe my name this 15th day of January, A. D. 1919. HAROLD D. ARNOLD.
