Abstract
445,486. Thermionic valve holders. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A., and MILLER, R. J., 5, Bentley Way, Stanmore, Middlesex. Oct. 31, 1934, No. 31254. [Class 39 (i)] Holders for electron-discharge devices, such as thermionic valves, with terminal pins engaging sockets in the holders include a lever 19, Fig. 1, with two arms at right angles pivoted at 23 near its bend so that an outward pull on the handle 21 raises the arm 20 against the base of the valve and ejects the valve from the holder. The arm 20 and the sockets 30 for the pins of the valve are held in place by three rectangular, insulating plates 2 .. 4 in the base 5 of a brass body 1. The body 1 is slotted at 8 to engage a side pin on the base of the valve and so to ensure correct insertion of the valve. Each socket 30 comprises half cylinders 29, Fig. 5, pressed together and against a contact pin of the valve by a split collar 31, a copper wire 32 providing a circuit connection.
