Abstract
619,616. Delivering measured quantities of liquids. NON-DRIP MEASURE CO.. Ltd., and BERWICK, A. G. Dec. 16, 1946, No. 37033. [Class 106(v)] In a device for delivering measured quantites of liquid, of the kind in which the delivery operation is effected by application of upward pressure to an axially movable member through which the liquid flows into a receptacle, the member 11 has a chamfered upper end 29 which is arranged firstly to enter a chamber 16, in which it is a close but sliding fit, to effect substantial closure of the liquid inlet passage 7, and secondly to engage the end of the stem 20 of an air inlet valve 22 disposed externally of the measuring chamber so as to open the valve the final movement of the member causing its upper end to seat on the lower end of the passage 7 to effect complete closure of the passage and allowing discharge of the liquid from the measuring chamber through transverse ports 27 and passage 28 in the member. The measuring chamber is formed in two parts 1, 2 with an interposed sealing ring 3, the parts being secured together by a screw-threaded member 5 forming part of a bracket by which the device may be supported. The inlet passage is formed by a tube fitted with the usual baffle 9 and surrounded by a cork or other yieldable member 8 to make liquid-tight connection with an inverted baffle. The valve 22 is loaded by a spring 25 and controls communication between a post 17 leading to atmosphere and a port 19 opening into a frustro-conical portion 15 of the part 1. The flange of the valve is fitted with a sealing ring. and its stem is formed with flats or flutings 21 or is of reduced diameter over parts of its length. The valve may be arranged for horizontal movement as shown or on an axis slightly inclined to the horizontal. The member 11 is urged downwardly by a spring 36 and is fitted with arms 12 for engagement by a receptacle. The surface of the lower part of the member makes wiping contact with a resilient washer 34 to retain any liquid which tends to leak down this surface. A sealing ring 14 on the member engages the base 13 of the measuring chamber to prevent leakage when the device is inoperative.
