Abstract

190,930. Guerin, W. L. Jan. 23, 1922. Signalling any of a number of possible indications. -A portable apparatus for signalling the location of vacant theatre seats has two differently coloured sets of electric lamps 16, 25 to indicate groups of seats and isolated seats, controlled by switches in such a way that closing of the third switch of a set, say, to indicate three vacant seats involves the closing of the first and second switches, illuminating three lamps. Each of the spring contact members 8 on a hinge 7 common to the set co-operates with a contact 9 connected to a lamp 16, and has a right-angular extension 29 overlying the main portion of the preceding contact member. Closing of a switch bridges the corresponding lamp across the battery connections 6, 13.
