Abstract

449,815. Vacuum pipe lines. BOOTH, R. N., Neasden Court, Neasden Lane, Neasden, London. Feb. 21, 1935, No. 5604. [Classes 99 (i) and 99 (ii)] [See also Group XXIX] In a vacuum cleaning system for theatres &c. in which pipe lines leading to a vacuum cleaning machine e.g. in the basement are permanently installed and hose connection points are provided, the points are provided with flaps a pivoted to be swung edgewise across the bores and to be returned to obstructing position by springs e. The flaps may have bevelled cutaway portions h engaged by lugs on the connecting nozzles of the hose pipes which are then turned to swing the flaps aside. Holes a<1> may be formed in the flaps enabling the suction in the system to retain the doors D of the points in closed position.
