Abstract
497,765. Valve-discharge water-wastepreventers. KJAERSGAARD, M. A. June 28, 1937, No. 17966. Convention date, June 27, 1936. [Class 26] In a water-waste-preventer in which a valve returns to its closing- position under the action of gravity or a spring or both and against a resistance ceasing after a predetermined time, the quantity of the discharge is varied by moving the valve predetermined distances from its closing- position. The valve 7 can be moved in a cylinder 5 from a position in which it seats upon the cistern-outlet 4 by one arm 17 of a double-armed lever ; the other arm 18 of the lever is connected to chains 19 fitted with stops 20 coacting with a slotted member 21, whereby the arm 17 and therefore the valve may be moved to the extent required. The descent of the valve is opposed by the partial vacuum which tends to form in the cylinder above it, the amount of such vacuum being controlled by a preferably adjustable aperture 22, or by the fit of the valve in its cylinder or of a one-way closure-valve 11 in the upper part of the cylinder. An aperture 23 in the cylinder-wall serves to break the vacuum after the valve has travelled a certain distance, while apertures 8 in the lower part of the cylinder place the cistern and outlet in communication. The cistern is filled at 12, air escaping by a pipe 13 until the latter is closed by a pivoted float 14, whereafter the supply continues until the pressure in the mains and the cistern become equal.
