Abstract

648,076. Holders for discharge tubes. FOOT, V. A. Nov. 17, 1948, No. 29898. [Class 38 (i)] A holder for thermionic valves of the type in which the valve pins lie in a line, such as miniature valves for deaf aids, comprises a block of insulating material formed in one piece or in two parts A, B as shown, with holes B<SP>1</SP> extending therethrough, each containing a contact bent up from wire or strip to form a closed elongated figure which extends through the hole and has enlargements at its ends to retain it therein. Conveniently the holes B<SP>1</SP> are rectangular and each contact comprises part-cylindrical end portions C, C<SP>1</SP> forming the said enlargements, joined by a straight portion C<SP>2</SP> with which overlapping ends C3, C<SP>4</SP> of the contact lie parallel when in position in the block. A valve pin is received between the ends C<SP>3</SP>, C<SP>4</SP>, the latter end being extended and bent parallel with the outer face of the block to form a connecting tag. A circular rod of insulating material may be passed through the portions C after the contacts have been inserted in the block.
