Abstract: 17,653. Lake, H. H., [Gates, C. E.]. Aug. 14. Measured quantities, delivering.- A dispensing-apparatus, for sodawater fountains and other purposes, consists of a series of syrup containers C, which may be open at the top or closed by suitable covers d, arranged in compartments A, each one preferably closed by a panel a hinged on a continuous rod B. The container consists of a main chamber C and a measuring-chamber E below it, from which the syrup is delivered through an opening in the thimble e<1>. On pulling down the actuating-handle F, forks e<5> attached to a pistonrod d<3> are raised, and with them the piston also. This raises a valve e<3> from a seating e<2> on the thimble e', allowing the liquid in the chamber E to be discharged, and at the same time a plate e is raised and covers the connecting-holes c<2> between the main chamber and the chamber E. The upward motion of the piston-rod d<3> causes recesses d<8>, in the walls of a thimble d<2> which is fastened to the base of the main chamber, to communicate with openings d<6> from the hollow interior of the piston, so that air passes in at apertures e', up the hollow piston, and into the chamber E by way of the recesses, thereby assisting in the delivery of the syrup. On releasing the handle F, the action of a spring d' upon a collar d<5> loose on the piston-rod d<3> causes the valve e<3> to engage the seating c<2>, thus closing the discharge chamber, and at the same time the plate e is removed from the holes c<2>, allowing the chamber to be refilled. The collar d<5> presses on packing d<7> upon the base of the thimble d<2>, preventing any back-rush of liquid into this thimble. Two modifications are described, in which the container is connected by a conduit with a small chamber above the measuring-chamber, these two chambers forming an approximately - spherical casing. In one case, the actuating-valve is of the same construction as above, while in the other the spring d' is dispensed with and the return motion of the piston obtained by means of the pressure of the liquid upon the plate e, the orifices c<2> in this case being a continuous or divided circumferential opening in the bed-plate. In another modification, Fig. 7, the container is connected with the measuring-chamber E by means of a conduit M and a plug valve N. The valve is so constructed that, when the conduit is filling the chamber by way of an inlet x, the connections to the outlet n by way of a duct y, and to the air by way of a passage z<1>, are shut. When the valve is rotated by a handle p, which is fitted with a square socket p fitting over the extension n, and the passage x thereby closed, the duct z leading to the air is put into communication with the passage z<1>, and the two ends of the duct y into communication with the chamber E, so that the contents are discharged through a tube connected with the centre of the duct y and passing down through the end n. A spring O may be provided to lessen the wear, and an additional nozzle Q may be screwed on the extension n and provide a shoulder for the spring to work against.
