Abstract: 11,612. Hampson, F. G., and Swales, H. June 6. Measured quantities, delivering.-Relates to apparatus for use on counters, tables, and the like in which by turning a handle or pushing a knob, or by equivalent mechanism, a receptacle is filled with a liquid such as beer, wine, or water, the liquid is aerated, and the aerated liquid is delivered as required. The receptacle in which the aeration takes place may be of such a size or be provided with a graduated gauge glass so that a measured quantity of liquid can be drawn off. In one form of apparatus, shown in Fig. 3, the receptacle C is normally empty but can be filled by rotating a milled head or the like F" which operates a spindle F" which acts first to close a snifting valve G<3>, to close by the cam F<7> the discharge valve I<2>, and then to draw back a valve F so as to allow water to pass through the pipe E and chamber E', gas through the pipe A' and chamber A<2>, beer, wine, syrups, &c. through the pipe B<1> and chamber B<3>, and all thence into the receptacle C. The head F<14> then remains locked in place until a pressure has been created in the receptacle C sufficient to force back the spindle F" which releases the head F<14> so that the spindle under the influence of the spring F<16> returns to its original position. The rearward motion of the spindle F" causes the valve F to be closed and then the valve G<3> to be opened which allows excess of gas in the receptacle C to pass away through the pipe G<1>, after which the cam F<7> turns into such a position that the spring I can open the discharge valve I<2>. This apparatus can be arranged so that the receptacle C, instead of being normally empty, is normally filled with liquid which will be discharged by operating the handle or push piece. In the modification shown in Fig. 11, the liquid is subjected to the operation of a jet of the gas at the nozzle L, so as to spray or atomize the liquid, or to suck the liquid so as to introduce it into the apparatus. The gas and liquid entering the chamber C push back a non-return valve M which is connected by a flexible cord M<5> to a piston N. When it is desired to draw off the liquid, a cam P<1> is turned so as to raise the piston N whereby the valve M is forced back on its seat, and ultimately the head of the valve 0<1> strikes against the top of the chamber C and is thereby opened allowing the excess of gas to escape into the air. The continued turning of the cam raises the tube C<3> and compresses the spring I' whereby the discharge valve P is opened. In the modification shown in Fig. 12, the receptacle C is normally filled with aerated liquid, and the pushing-in of a knob R<1> causes the supply of liquid and gas to be cut off and at the same time opens holes Q<3> which allow the excess of gas to escape, and the reduction of pressure enables a spring to act to open the discharge valve. Pressure gauges.-Fig. 13 shows a pressure gauge for attachment to the chamber C. It consists of a spring-regulated piston J' having an indicator J<3>. Fig. 14 shows a form of pressure-reducing valve K<1> is the gas inlet. The valve K<4> is normally kept open by the action of a spring K<12> on a flexible diaphragm K<10>, but any excess of pressure causes the valve K<4> to be closed until the pressure is reduced to the required degree. The operating handle or push-button may be set in motion by any well known automatic coin-freed mechanism.
