Abstract
8906. Davy, W. J., and Thomas-Davies, G. April 7. Couplings for arc and other lamps that have to be raised and lowered. Fig. 1 shows one construction. The hood or mautle a is screwed to the supporting arm or bracket and is fitted with a flange p to which an insulating-block f is secured. The block carries two concentric conducting-rings r, r<1> to which the conductor is connected. They carry depending spring contacts g. On the top of the lamp is fitted another disc e fitted with concentric rings s, s' adapted when the lamp is raised by the cord d to engage the springs g. The rings s, s<1> are connected to the lamp terminals. The cord d is connected to an insulating - block which passes through an opening in the upper disc and so forms a guide. The pulley b is fitted within the mantle, and the cord passes through an inclined tube c to prevent the ingress of rain &c. In a modified form, the helical springs g are replaced by curved plate springs, and additional elasticity may be given by mounting the disc e on springs.
