VACUUM TUBE ELECTRODE SOCKET William B. Wilson, Huntington Park, Calii'., assignor, by mesne assignments, to Metlox Corporation, Ltd., a corporation of California Application July 5, 1929. Serial No. 376,052

1 Claim.

and a coiled spring contact element within the casing formed by the insulating elements, all arranged for perfect contact, for ease of installation, and for eflicient functioning under all conditions.

Another object is to simplify the construction of the socket, and the method of its application to a socket holder, and to function with various forms of gas and vacuum tube terminals.

One form in which my invention may be embodied in practice is shown in the accompanying drawing wherein- Figure l is a sectionalelevation of the socket applied to a vacuum tube terminal. Fig. 2 is a plan view of the clamping ring for securing to the holder. Fig. 3 is a side elevation of the socket. Fig. 4 is a detail view of the spring contact member. Fig. 5 is a side elevation of the threaded clamping member which supports the container. Fig. 6 is a detail view of a modified form of vacuum tube electrode which may be applied to my improved socket.

In the embodiment illustrated, a container 11, of glass or porcelain, has screwed thereto, a metalclamping member 12, which has a flange 13 adapted to project over the surface of 'a holder wall 14, which is pierced with a hole 15 to receive the same. A clamping ring 16, is disposed on top of flange 13, and is firmly held in engagement therewith by means of cap screws which extend through the ring 16 and the holder wall 14, thus serving to maintain the rubber cap 26 in position at the top of the container.

The container is provided with drainage apertures 17 at the bottom thereof thereby preventing moisture from accumulating in the container.

ing post 18, disposed The bindcentrally in the bottom of the container, is provided with a washer 19, which clamps the contact spring member 20, in

position. Contact member 20 is fashioned in the form of a double truncated cone thereby affording perfect contact with electrode terminal 21, and

permitting perfect contact with various forms of terminals, affording a large tolerance in manufacture, providing for expansion and contraction of the vacuum tube, and allowing an elastic limit in inaccuracies in the installation of the vacuum tube.

The service termin post 18, by a nut 23,

al 22, is secured to binding having an insulating cover 24. Clamping member 12 and clamping ring 16, are secured in position by screws 25, engaging with the holder wall The device as herein described and illustrated, provides more perfect electrical insulation and more perfect contact for and with the terminal electrode of a gas or electrode from insect life, and from inclement vacuum tube, protects the weather, and the other advantages set forth.

What is claimed is In a luminous tube mounting, a threaded ring adapted to be supported on the edge of an aperture, a container threaded to the ring, a separable connection device in the container, a resilient,

ring, including a number of screws that serve also to hold the ring in pl ace on the mounting.

WILLIAM B. WILSON.
