Abstract

245,878. Levi, S. J. Oct. 30, 1924. Two-part couplings.- A set of parts for use in wireless apparatus includes two or more spring contacts d with screws c and nuts d for securing them below a panel p and a template for use in and drilling the panel. Each of the springs is L-shaped with one leg curved concavely to the other leg, which is formed with a hole to receive the screw. Soldering lugs g are clamped to the springs and panel by the nuts. The holes b in the panel are of larger diameter than the pins a and are arranged eccentrically to the pins so as to prevent rotation of the valve &c. Reference has been directed by the Comptroller to Specification 222,545, [Class 39 (i), Electric lamps, Arc &c.].
