Referring to the reference characters in the drawings numeral 10, re resents a casing formed of a phenolic con ensation roduct, and hollowed interiorly as at 11, an con taining a series of chambers 12, extending upwardly from the base towards the top of the casing, as shown in Fig. 3, and terminatin adjacent the top 14 of the casing, in whic there are formed a series of apertures 13, leading from the top 14 of the casing into the chambers 12, the apertures 13, being cylindrical within the top of the casing and being adapted to assume a semi-cylindrical form, alon the length of the chambers, whereby portions of the prongs 15, of a vacuum tube 16, or other electrical element, will be positioned within the cylindrical cut out portion extension of the aperture 13, while the other halves of these prongs, will project into the chamber 13 proper, for contacting with the conductors, the function of which will be later described.

A hub 17, is formed centrally of the casing,

and projects downwardly therein for a greater portion of its depth, there being adapted to be passed through an aperture 18, 1n sald hub, an eyelet here being indicated as the preferred fastening means for mamtammg the base cover 20, and carrying the conductor is observed that the carrier or cover member 20, comprises of a flat disk formed preferably of a phenolic condensation product, having a series of apertures 21 therein, through which eyelets 22, may be passed for fixing the contact members 21 thereto, in a manner to be later described.

A central aperture 23, is formed within the carrier, for providing for means, whereby the eyelet 19, may be passed through .for fastening the carrier to the casing, at the hub portion 17 thereof. A cut out portion 24, is formed on the outer periphery of the carrier 20, which aperture is adapted to have fit therein a rojection 25, formed on the inner surface 0 the casing 10, whereby the carrier with the conductor members 21 thereon, may be readily and easily positioned in the hollow portion 11 of the casing, so that the flexible contact portion of the conductors maybe properly positioned within the chambers 12, with a minimum of effort, and so that once the carrier with its conductors is positioned in assembled relationship, it cannot be ro-- tated.

Referring to Figures 3, 4, 5 and 6, it is seen that the conductor comprises a length of flexible metal, either tin, brass or aluminum, having a base portion 26, adapted to rest flat against the carrier 20, and having a plurality o apertures 27 and 28, of which 28, is adapt- 1 ed to be aligned with the apertures 21, in the carrier, and through which an eyelet 29 is adapted to be passed to fix the conductor to the carrier; the aperture 27 formed at the extremity of the flat portion of the conductor being adapted to form the contact terminal with the remaining elements, with which this device is applied. Ofi'set and angularly disposed of the base portion 26 of the conductor, there is adapted to be formed the pressure head of the conductor, comprising a prong contact portion 29, at right angles to the base 26 of the conductors, and the wall contact portion 30, the wall contact portionforming the extremity of theconductor, being bent over uipon itself to form an angularly disposed exiblep essure contacting ortion-,cooperating wit the wall of the c amber 12, as shown in Fig. 4, and the portion 29, being adapted to be contacted by the prong 15, as

' shown in Fig. 4. A cut out portion 31, is

formed in the conductor and extends for a portion of the length of the offset portion 29, and the flat. portion 26, the purpose of this aperture being to provide for facility in bending the conductor into position, and simplicity in structural formation thereof.

' When the carrier 20, with the projecting resilient conductor portions 21, is assembled as in Fig. 5, this assembled section of the deviceis forced into the hollow ortion 11, of the casing 10, asshown in Fig. 2, to provide for the structure shown in Figure 1, there being formedin the base of the casing, a series of channels 32, through which the extremities of the flat portion'26, of the conductors may pass for interconnection, to provide for the terminal connection of the socket, the said flat portion 26, of the conductor being adapted to extend considerably above the base'of the casing, so as to prevent the conductor from contactingwith any other conductors or devices within the radio receiver, which may be extended on the base or subpanel of'the same, adjacent the socket.

As seen in Figures 2 to 6 inclusive, the conductor member 26, is adapted to have the contact portion 29 of the flexible pressure portion 30, formed integral therewith, positioned Within the respective chambers 12, wherein the depending prongs 15 of the vacuum tube or other electrical devices, are adapted to be insertable with one half or equivalent fraction of the prong, being positioned in the groove 13, formed adjacent-the chamber, and the other projecting half, thereof, contacting with the contact portion 29 of the conductor, spaced from the opposing wall by the flexible pressure member 30, formed integral therewith.

The angular groves 32, formed in the base of the casing are disposed angularly of the chambers 12, so that the flat portion 26, of theeonductor 21, oflset from the contact por-- tion 29 thereof, may be retained in fixed position in the casing, for providing the terminal contacts with the remaining elements of the receiver through the apertures 27 thereof. Apertures 33 and 33' are provided in the base of the casing, for the passage therethrough of the fastening means to fix the casing to a subpanel or any part of the receiver to which the socket is desired to be attached. I

It is obvious that various changes and modifications may be made to the details of construction without departing from the general spirit of the invention as set forth in the ap pended claim:

What I claim: A socket for a vacuum tube, comprising a casing having a series of chambers formed interiorly thereof adjacent its periphery, ap-

ertures disposed in the top of said casing, forming the termination of said chambers, an aperture formed centrally in the top of said casing and merging into a smaller aperture extending to the base of said casing, a carrier late positioned at the base of said casing or enclosing the chambers therein, resilient conductor members positioned in the respective chambers for contacting with the prongs of a vacuum tube passing through the apertures leading thereto, said conductors being fixed intermediate their ends to said carrier member and extending radially from said carrier member for forming contacts with elements in a radio circuit, said conductors being adapted to rest in cutout portions along the periphery of the casing at the base thereof, an aperture disposed centrally of said carrier in line with the central aperture of the casing, and a rivet for fastening the casing and said carrier at their central apertures, and a cutout portion on the outer periphery of said carrier, and a projection in the base of said casing for positioning the carrier, so as to locate the contact members in their proper chambers, and to prevent displacement thereof.
