An, object of the invention resides in pro;
viding an anode,v grid, and cathode of a special form, arranged-inn co-related man-- men for providing mcreasedieificiency over other tribes of this t a.
Another object of t e invention resides in providing an audion wherein the anodeand the grid are of helical form. arranged, in concentric relation with similar points .in
each convolution in the same radial relation, and the filament cathode is arranged inf, cylindrical form with the filament wire 'ex-- tending in zig-zag relation forming the cylinder, so that the wires are arranged at substantiall right angles to those of the helical grid. an anode, for increasing the efiiciency, of a tube of this character, oversimilar tubes" now in use, and at the same time providing a relation of elements whereln the current necessary'to produce this increased efficiency 1 is comparatively small in relation to the current consumption of tubes now in use. A further object of the invention resides in providing aconvenient supporting element adapted to mount all of the tube elements.
The invention also comprehends' other objects and improvements in the details'fof' construction and arrangement -'of parts which is described in the following description and claims, directed to a. preferred form of the invention, it being understood, however, that variations may be made from this structure within the scope of the claims.
In the drawing: I Figure 1 is a sectional view through a tube constructed according to the invention showing the coils in elevation.
Figure 2 is atransverse sectional view II taken onthe'line 2-2 of Figural.
1 indicates the base of a supporting memher having a stem 2 extending from the central portion thereof and provided with a pair of spaced annular flanges 3 above the ase as clearly shown in Figure 1 of the drawings, between which are a pain of.
smaller annular flanges, which are also arranged in spaced relation with each other and from the flanges 3. The smaller annular flanges are provided adjacent the edge.
thereof with a plurality of spaced hooks 5 adapted to receive and support the filament cathode 6, which it will be noted. extends around the edges of the flanges 4 and beit to incandescence; I I I 1 I Arranged in concentric "relationwith the cylindrical cathode and the periphery of the tween said flanges in a zigzag relation to form a cylindrical shaped filament element, thezterminals of which extend throughthe stem 2and the base 1 for attachment to the 60 contact 7 through which the source of en- I .ergy is supplied tothe filamentfor heating I flanges 4, area plurality of vertical sup-v porting rods. 8, which extend and are embed= f ded in the spaced flanges 3; Another set of supporting rods indicated at 9 are arranged.
.1n concentric relation with the supporting rods 8 adjacent the outer edge of the flanges 3; as clearly shown'in Figure 2 of the draw ings, the free ends of the supporting rods I 9 beingalso embedded in the flanges 3.'t-he' i I supporting rods 8 and 9 being of a'suitable I insulating material, the reason for which will follow; I I
A grid is, mounted on the supporting rods 8 between the flanges 3 and is composed of a wire member arranged inhelical form, the
convolutions of which are equally spaced throughout the length of the wire, one end of the'same being secured in the uppermost flange 3 as indicated at 11, while the other 'end extends through the lower flange 3 as indicated at 12 and is secured to a terminalwire 13 connected with the contacts 14 with which the proper circuit connection may be made." X
The anode indicated at. 15 is of helical I form, beingformedof a wire member, hav
'ing one end embedded in the upper flange 3 as indicated-at 16 and wound helically on the outer supporting. rod 9 with the con 'volutions in equal spacedrelation correspending to the convolutions of the grid 10,
and; having the lower ends extending through the lower flange 3 as indicated at 17 and connected with a terminal member 18,
providing a circuit connection-with the con- I tact 19, so'that theanode may be intercom nected at a desired point in a circuit.
It will be noted from the description of Figure 1, that the convolutions of the anode and grid are arranged to form cylindrical elements arranged in' concentric relation with COIIBSPOIKllDQ, points of each convolution arranged 1n the same radial relation. 1 i
It will be noted from an inspection of f Figure 1., that the filament extends substan- I tially at right angles tothe direct-ion of the helical grid and anode, so that a thorough penetration of the grid and anode will result from the electrons discharged by the cathode.
By the arrangement of the cathode, the grid, and the anode as above described, a more efiicient cooperation between these elements will result so that amplification will be increased as well as the range of eitectiveness of the tube as compared with other tubes of this character now in use.
The construction of the support with the base 1 also provides for the convenient mounting of the tube on the annular iiiclined edge thereof as indicated at 21, so that a strong joint will be provided, which will withstand the pressure after the tube or container 20 is evacuated. 'A suitable protecting element, 21 is provided on the lower end of the tube 20 and the base 1, which also mounts the usual ring member 122 for fitting and holding the tube in a socket.
What I claim as new is 1. An audion tube, including a supporting element having a base member of annular form, a stem extending upwardly from the central portion of said base member and formed with a pair of spaced disc-like fian 'es above the base, a cylindrical anode carried by the flanges, a cylindrical grid arranged in concentric relation to said anode and carried by the flanges, supporting means on said stem between the flanges, and a cylindrically arranged filament cathode mounted on said means in concentric rela tion with the grid and anode between the flanges, leads extending through the base of the support for the anode, grid and the cathode. and an evacuated container mounted on the periphery of the base and cooperating therewith to house the sup ortinp' member and the elements carried t ereb i 2. An audion tube, including an evaciiated container, 2. suppi'irting member mounted in said container and having a stem extending axially thereof, a pair of substantially large annular i; tegral flanges mounted in spaced relation on said stem, a pair of small annular integral flanfles mounted on said stem between said largeiianges, and in spaced relation with respect to each other and said large flanges, an anode ef'cylindrical form and a grid of cylindrical form mounted in concentric relation on said large annular flanges, and a cylindrioally arranged filainentary cathode mounted on the small annular flanges having a filament wire extending in zig-zag relation throughout the cylinder from end to end thereof, and directly connected to said small flanges. t In testimony whereof I aflix my signaure.
