Abstract

594,872. Delivering measured quantities of liquid. BERWICK, A. G., and NON-DRIP MEASURE CO., Ltd. July 3, 1945, No. 16925. [Class 106 (v)] In a device for delivering measured quantities of liquids comprising a housing formed at the upper end to engage the mouth of a bottle or container and a base wherein a valve operating member is movably mounted, a single threaded device serves to secure the entire assembly in operative condition and a stop device is embodied in the base so that the pressure of operation is taken by a robust portion of the housing. The housing comprises parts 1, 2 and 3, made, in common with most of the parts, of plastic material, a socket 4 substantially of the form described in Specification 455,269 being formed in the part 1, which also carries a plate 5 with a projecting portion 6 for fixing detachably in a supporting stand, the plate 5 engaging a resilient ring 7. The cut away portions 8 of the section 2 exposes the transparent wall 9 of a measuring chamber which is joined by sealing washers 50 and 51 to the section 1 and to a flange 13 of the base 3, the whole being secured together by the nut 11. The axially movable operating element 14 has a central passage 15, terminating in an outlet 16 and a lateral port (or ports) 17, and also a detachable head 19, the flange 20 on its upward stroke striking a spring loaded grooved air valve stem 21 which carries a sealing washer 23. A valve member 33 co-operates with a spring 36 and a supporting ring 37 to make it selfaligning on the seating surrounding the inlet 34. A sleeve 39, formed in the base member 3, is sealed by a resilient member 40, having an inner edge free to move slightly within the annular space formed by chamfered surfaces 41 and 42. A sleeve 44 vented at 53 carries a spring 45 and comes into contact with a ring 43 before the head 20 strikes the valve member 33 thus transferring the operating pressure to the base member 3. The operating member 14 terminates in a drip catching device essentially similar to that described in Specification 455,271, [Group XXVIII], but which in this case has a metal casing 46 and metal arms 47. In a modification, Fig. 4, the housing parts 1 and 2 are formed in one piece and the components are held together by a nut 53a. Specifications 455,266 and 455,347 also are referred to.
