Abstract
412,939. Needle - - point couplings. LAMBERT, W. R., 2, Pocock Street, London. Jan. 3, 1933, No. 138. [Class 38 (i).] A lamp holder of the kind in which the contacts 4 are connected with rearwardly projecting points 7 that penetrate a cable 12 secured in a transverse groove in the holder by a cap 8, has a resilient packing ring 10 inserted between the cap and the body 5 of the holder, a diametric portion 11 of the ring 10 lying in the groove and transmitting the pressure of the cap to the cable 12. The spring contacts 4 are mounted in the pointed hollow contact blocks 13, the ends of which are hexagonal to enable the blocks to be turned by a spanner to screw them in place.
