SAVES WASTAGE OF LIGHT

Device That Automatically Turns Off Power Has Been Found to Be of Real Value.

One of  the considerable sources of fuel waste is the unnecessary burning of electric lights.  A large percentage of lights are used chiefly for limited periods, as for instance in cloak rooms.  They are turned on and then heedlessly left burning.  Thus we are constantly recommended to shut off needless lights as a matter of national saving.

An invention designed to remedy this condition is the work of J.E. LEWIS of New York.  By pushing a button the light is turned on and glows for a predetermined period * say, five or ten minutes * and then is automatically cut off.  The device has been tested and found practical and seems useful in the way of checking electric light waste.
