UNITED STATES'l j 1,560,692 PATENT OFFICE.'
WILLIAM G. HOUSKEEPER, NEW YORK, N. Y., ASSIGNOR T WESTERN ELECTRIC COMPANY, INCORPORATED, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK.
nnncrnoN-DISCHARG DEVICE.
Application led June 13, 1923. Serial No. 645,053.
To all whom at may concern:
Be it known that I, WILLIAM G. Hors- KEEPER, a citizen of the United States, residing at New York, in the county of New York, State of New York, have invented certain new and useful Improvements in Electron-Discharge Devices, of which the following is a full, clear, concise, and exact description.
This invention relates to' electron discharge devices and has for its object a strong, eflicient and inexpensive vacuum. tube capable of being opera-ted from asmall4 -source of power.
This object is attained by providing a fiattened cylindrical electrode supported from the stem of a containing vessel by a collar integral with the anode, providing an insulating member4 supported by the anode and .supporting the grid and cathode by said member.
Referring now to the drawings:
Fig. 1 is an elevation, partially broken away, of a-vacuum tube-embodying theinvention; Fig. 2 is a vertical section of the lower portion of Fig. 1; Fig. 3 is a section transverse to the axis of the electrodes, and Fig. 4 is an enlarged elevation of a portion of the anode. j
An enclosing vessel is provided with a reentrant stem 11 terminating in a'press 12. An anode 13 is supported within the vessel 10 from a collar 14, surrounding the stem 11 and Aheld in place thereon by friction. The anode comprises a'pair; of plates 15 having their ends bent substantially at right an les to their main portions, one of the en s ,being substantially longer than ythe other, the long end of one plate being welded to the short end of the other as at 16. An integral projection 17 extendsfrom. one edge of eachz plate in alignment with the longer bent end and terminates in a substantially semi-circular crimped member 18. The ends of the semi-circular crimped members are welded together as at 19 to form the cylindrical collar 14. A short projection or tab 20 extends from the opposite edge of veach plate 15 in alignment withy the longer bent end portion thereof and is formed into a tubular member 21 near its end. A stren hening rib 22 is pressed outwardly on eac plate 15 from and including the pro; ection 20, through the projection 1 and colar portion 18.' The arrangement of the collar 14 relative to thestem l11 is such that the projections 17 p'ass along the ends of the press and are t erefore in contact with the glass for approximately half their length, thereby adding to the rigidity of the anode support.
A block 28 of lavite o'r other insulating material receives in apertures, provided at either end thereof, the members 21 and rests on the shoulder provided by the projection 20, the ends of the members 21 being fiattened to clamp the member 23 in position. Within the anode'13 is arranged-a grid elec'- trode 24 which com rises a pair of frame members 25 and a ateral wire 26 wound around them to form a flattened helix, one end of each frame wire projecting slightly beyond opposite ends of the helix, the helix being symmetrical with respect to the plane of the frame wires. rlhe projecting end of one of the frame wires is welded to a supporting wire 27 Sealed in the press 12 and the projecting end of the other frame wire is loosely mounted in an aperture in the insulating block 23 whereby the grid electrode is free to expand when heated during the operation of the device.
A resilient helix 28 has one end resting on the block 23 and has attached to the other end a suspension member '29 which passes through the helix 28 and an aperture in the block 23 terminating in a hook. A filament 30 isstrung over the hookof the suspension member 29 and has its ends welded to the supporting wires 31 sealed in the press 12.
The supporting wires 27 and 31 also act as the leading-in wires for their respective electrodes, and a leading-in wire 32 sealed in the press 12 is attached to one of the projections 17 to .establish connections for the anode.
lThese leading-in wires are led down through the interior of the stem 11 to contact terminals 33 mounted in an insulating disc 34,
tions of each plate being of unequal length and connected to dissimilar portions of the other plate, and a projection from each plate in alignment with the longer end and terminating in a semi-circular member, said members being joined together to form a collar.
2. In an electron discharge device, a flattened cylindrical anode comprising a pair of plates, the main portions beingparallel and their ends bent substantially at right angles to the main portions, the end portions of each plate being of unequal length and connected to dissimilar portions of the other plate,.a projection from each plate in alignment with the longer end and terminatingin a semi-circular member, sai'd members being joined together to form a collar,
and a strengthening rib traversing said longer end portion, projection and collar.
. 3. In an electron 'discharge device, a fiat tened cylindrical anode comprising a` pair of plates, the main portions being paralleland their ends bent substantially at right angles to the main portions, the end p0rtions of each plate being of unequal length and connected to dissimilar portions of the other plate, aprojection from each plate in alignment with the longer end and terminatlng ,inr a semi-circular member, said members bein joined together to form a collar, a strengt ening rib traversing said longer end portion, projection and collar, said rib terminating in a post, an .insulating member having apertures to receive said post, and another electrode supported from said insulating member.
4. In an electron discharge device, a fiattened cylindrical anode comprising a pair of plates, the mainportions being parallel and their ends bent substantially at right angles to the main portions, the' end portions of each plate being of unequal length and connected to dissimilar portions of the other plate, a projection from each plate in alignment with the longer end and terminating in a semi-circular member, said members being joined together to form a collar, and a strengthening rib traversing said longer end portion, projection and collar, sai rib terminating in a post, a tab pro'- jecting from each plate and providing a shoulder adjacent said post, aninsulating member having apertures to receive said post, and means to clam said insulating member against said shoul ers. j
In witness whereof, I hereunto subscribe myname this 2nd day of June A. D., 1923.
