Signal Clocks Solve Emergency Guard Problem in West's Largest Hospital
By LUCIUS S. FLINT
Electric clocks, which are scattered through the building corridors, solved the call problem. These clocks have light bulbs behind the faces for illumination. By replacing white bulbs with red ones and re-wiring the sockets in series, connecting the special circuits with a single pushpull on switch in the telephone operator's booth, the management had an almost instantaneous call system.
The hospital is normally equipped with hundreds of telephones. Since the war emergency arose, scores of additional ones have been installed-some out on the grounds, some on the building roofs and others at equally strategic locations. Thus, should need for a guard arise, the operator, being informed, has only to push a switch which turns on the red light in every clock in the hospital. In a matter of seconds one guard would come within visual range of a clock.
