Patented Apr. 29, 1947 UNITED STATES PATENT OFFICE APPARATUS ronpnuvnamc MEASURED QUANTITIES or LIQUID BY VOLUME FROM BOTTLES on SIMILAR VESSELS Norman F. GottschalkfSouth Euclid, Ohio Application April 27, 194aseria1 Nate's-596 1 Claim. 1

This invention relates to an apparatus for delivering a measured quantity of liquid from a bottle or similar receptacle and consists in the construction, combination and arrangement of parts associated therewith whereby th flow of liquid through the delivery pipe from the measuring chamber is cut off While being filled with liquid passing from the receptacle through the supply conduit thereinto, and subsequentl cutting off the liquid passing through the supply conduit while the measuring chamber is being emptied of its contents.

Reference is to be had to the accompanying drawing forming part of this specification in which like reference characters indicate correspending parts throughout the several views, and inwhich:

Figure 1 is a vertical sectional view of the apparatus constructed according to the invention on the vertical center line of the complete onehalf of the apparatus, and showing the control valve 20 installed in operative position therein.

Figure 2 is a complete side view in elevation of the control valve apart from the apparatus.

Figure 3 is a sectional view through the complete apparatus on the line A A in Fig. 1. The control valve is shown in position in the apparatus in the cross section at 20 in the Fig. 3.

Figure 4 is a front view in elevation of the control valve apart from the apparatus illustrating '1 into the measuring chamber previous to the dispensing thereof.

Adjacent the supply conduit there is provided an air pipe 8, the upper end of which is provided with a notch 9 registering with the arcuate channel ill. The lower end of the air pipe 8 is tapered, the taper decreasing as it approaches the end, which is indicated in the drawing by the numerals ll. Obviously a restriction may be incorporated in the end portion of the air pipe to partially close the end thereof if desired.

In the arcuate channel there is provided an internal flange l2 having an opening I 3 therethrough, and beyond the flange there is formed (01. sea-442) 2 a segmental slot l4 in which the handle crime control valve operates, and which limitsit'siextent of operation therein.

Beyond the aforementionedsegmental slot there is provided a trap 15 having an opening Hi there:- in, open to the atmosphere, an air space I! and an orifice 18 that leads to the port is in the control valve 20 which has limited rotatioi'ial movement in the measuring chamber. When the 'aiorenamed port is in alinement with the orifice i8, the measuring chamber is in communication with the air space in the air trap, and hence with the atmosphere through the opening 16 as illustrated in Figure l. I

When wecommi valve "is moved toclose the supply conduit, it is moved counter-clockwise as indicated by the arrow Bin Fig.1, the handle 21 of the control valve is then in the position as indicated by the dotted lines as at 22, and the port 23 in the control valve is then in alinement with the orifice [8, hence the measuring chamber is again in communication with the air space in the air trap and the atmosphere through the opening l6 therein. The helical spring 24 is adapted to hold the control valve in the position shown in Figure 1 that is closing the delivery pipe, and to return it to that position when the supply conduit is relieved from its controlling infiuence.

The supply conduit and the air pipe pass through the cork 25, and the cork is inserted into the neck of the receptacle.

The two sections constituting the body portion may be held together by a tongue-and-groove joint as illustrated in Fig. 3, the groove is shown at 26, the tongue at 27, the relative position of the grooves is shown at 2-8 in Figure 1. The portions are held together in liquid tight engagement by cement impervious to the liquid.

The collars 28 and 29 are provided to reenforce the apparatus after it is assembled.

To dispense a measured quantity of liquid from the bottle or receptacle the bottle is tilted so as to bring the delivery pipe into a vertical position so that the liquid may flow through the supply conduit into the measuring chamber and be drained therefrom when the control valve is moved to open the delivery pipe. As the liquid fills the measuring chamber, the air therein is forced through the port I9 thence through "the orifice l8 into the air space I! in the trap l5 thence through the opening 16 into the atmosphere. When the chamber is filled, the valve is moved to release the liquid through the delivery pipe. When the delivery pipe is free, the supply 3 conduit is closed, and the port 23 is in alignment with the opening l8 hence in communication with the air space in the trap and the atmosphere through the opening 16, with the result that air is sucked into the measuring chamber in the dispensing operation.

Air enters the receptacle as follows, through the segmental slot M thence through the aperture I3 into the arcuate channel I0, thence through the notch 9 in the air pipe thence through the air pipe and out the restricted end into the liquid.

It will be understood that the above description and accompanying drawing comprehend only the general and preferred embodiment ofmy invention and that minor detail changes in the construction and arrangement of parts may be made within the scope of the appended claim without sacrificing any of the advantages of my invention.

Having thus described my invention what I claim is:

An apparatus of the class described, comprising, in combination, a body having a measuring chamber therein, a supply conduit for said chamber, a delivery pipe leading from the chamber, an inclined plane surface interposed between the supply conduit and the delivery pipe to direct the flow of material from the measuring chamber, a control valve located in the measuring chamber and having limited rotational movement therein, said control valve being of interrupted ring configuration and having a plurality of spaced ports, a handle connected to the control valve to operate it, an air pipe adjacent the supply conduit having a notch at its upper end and terminating in a restricted lower end, the notch registering 4 with an arcuate channel having a perforated internal flange therein and having therebeyond a segmental slot in which the handle of the control valve operates, the aforementioned slot providing an ingress for air to the arcuate channel and hence to the air pipe, a helical spring mounted in the arcuate channel its lower end supported on the upper surface of the internal flange, its upper and engaging the handle of the control valve, the ports in the control valves being movable out of and into registering position with an orifice leading to a trap having an air space and an opening leading therefrom to the atmosphere, one of the aforesaid ports being adapted to release air from the measuring chamber when the delivery'pipe is closed by the control valve in the filling operation of the measuring chamber, the other of the said ports adapted to permit air to be sucked into the measuring chamber when the supply conduit is closed by the control valve in the emptying operation of the measuring chamber.
