Abstract

249,048. Lampl, A. May 9, 1925, [Convention date]. Controlling lighting systems.-In devices for automatically inserting an equivalent resistance into a series circuit upon failure of one of the lamps &c. therein, and of the kind comprising a shunt. g of packed particles that serve to pass the current only when the lamp &c. connected to the terminals e, f fails, these particles are formed of metal. The shunt may be formed in a lamp-holder, as shown, or be placed across the leading in wires inside a lamp bulb.
