VENTED FLUID CONTROLLING VALVE Filed Nov. 2, 1934 35 INVENTOR.

p27 ORNEY Patented July 7, 1936 STES PATENT OFFICE 12 Claims.

My present invention relates to a fluid controlling valve, and more particularly to an improved valve for withdrawing fluids from a sealed container, such as a barrel or the like, wherein it is necessary to provide an air vent to facilitate a withdrawal of the fluid therefrom.

An object of my invention is to provide a new and novel form of valve for withdrawing a fluid from a sealed container having means for'venting the container when fluid is being withdrawn from the container.

Another object of my invention is to provide a new and novel form of vented valve having means wherein'the vent may be optionally rendered operable and/or inoperable when the valve is opened.

Other objects and advantages of my invention will be in part evident to those skilled in the art and in part pointed out in the following'description taken together with the accompanying drawing wherein there is shown, by way of illustration and not of limitation, a preferred embodiment thereof.

In the drawing, wherein like numerals refer to like parts throughout the several views;

Figure 1 is a vertical sectional view of valve constructed in accordance with a preferred embodiment of my invention,

Figures 2 and 3 are fragmentary sectional views taken from Figure 1, showing two positions of the parts when the valve is open,

Figure 4 is a view similar to Figure 1, showing a modified form of my invention,

Figures 5 and 6 are fragmentary sectional views taken from Figure 4, showing the relation of parts thereof when the valve is in its open position and the vent respectively opened and closed, and

Figure 7 is a vertical sectional view of a further modified form of my invention showing the parts of the valve in their valve closing positions.

As a preferred embodiment of my invention, I have shown in Figure 1 of the drawing a valve bcdy member Iii having a screw threaded extension that is adapted to be turned into the outlet of a barrel or the threaded outlet of a similar container. The valve body l0 also has a discharge outlet spout I2 over the inner end 01' which a valve member I3 is disposed. The valve member I3 is biased into sealing engagement 'with the inner end of the discharge outlet l2, by

means of a spring l4, and connected to the valve member l3 there is a valve operating stem IS. The valve operating stem l5 extends through the spring l4 and out of the valve; body ID at a point opposite the discharge outlet l2. At its upper end the valve operating stem I5 is provided with an operating lever l6 that is adapted to raise the stem l5 by compressing the spring l4 and thus opening the discharge outlet when pressure is applied thereto.

Extending through the wall of the valve body Ill there is a vent forming passageway I! which terminates at one end adjacent the inlet to the valve and at its other end adjacent the valve member operating stem l5. Cooperating with the vent forming passageway 17 there is a vent aperture l8, which is formed in the valve operating stem l5, where it will align with the vent forming passageway I! when the valve member I5 is raised to its valve open position. The vent aperture I8 is shown as extending diagonally and diametrically through the valve operating stem I5, so that when the valve operating stem I5 is in the position as shown in Figure 2 of the drawing, a vent passageway will be established from the atmosphere to the inlet end of the valve body l0.

At this point it should be stated that the operating valve lever I6 has a heel-like portion 1 9 that is adapted to be thrown over center to hold the operating lever IS in its depressed position when the operator has released same. The heel I9 upon the operating lever l6 engages an annular boss 20 upon the valve body I0 and, as a result, it is possible to rotate the operating lever l6 and the valve operating stem l5 into the position illustrated in Figure 3 of the drawing, without necessitating or permitting a closing of the discharge outlet l 2 of the valve. In this manner it is possible to optionally open and/or close the vent passageway formed, as above described, without closing the discharge outlet l2.

In Figure 4 of the drawing, the valve body I0 is similar to that illustrated in Figure 1, except that it is provided with a screw threaded portion 2| through which a threadedvalve operating stem 22 is adapted to extend. The threaded valve operating stem 22 has an operating handle 23 and at its lower end it carries a valve member 24 that is adapted to close the discharge outlet l2 when the threaded valve operating stem 22 is turned downwardly into the valve body Hi. In this em- .bodiment of my invention, like the one previously referred to, the body member I0 has a vent forming passageway I! that communicates with the threaded opening through which the valve operating stem 22 projects.

In order to provide for an opening of the vent forming passageway I! to the atmosphere, when the valve member 24 is in itsdischarge outlet opening position, the threaded valve operating stem 22 is provided with a cutaway portion 25 that is adapted to align with the vent forming passageway l1 and thus establish a communication with the atmosphere externally of the valve body ID. This cutaway portion 25 is provided by slotting the threaded valve operating stem 22 for a. short distance at a point adjacent the end of the vent forming passageway l1. Such a slotting will destroy only a very small portion of the screw threads at this point and, as a result, it will be possible, after the valve member 24 has been moved into its open position, to optionally open and/or close the air vent provided by the vent forming passageway l1 and the cutaway portion 25 upon the threaded valve operating stem 22. The position of thescrew threaded operating stem 22, when the valve and the vent are opened, is clearly illustrated in Figure 5 of the drawing, and the position of the threaded valve operating stem 22, with the valve open and the vent closed, is clearly shown in Figure 6 of the drawing.

In Figure '7 of the drawing, I have shown an embodiment of my invention, having a valve body 26 that is provided with a threaded inlet extension for attachment to a barrel or like container.

In addition to this threaded inlet extension, the body member 26 also has a discharging outlet spout 21 at its outer end. Located within the valve body 26 there is an annular valve seat 28 against which a valve member 29 is adapted to engage to close the valve. The valve member 29 is mounted upon a tubular valve stem 30 and it is biased against the annular valve seat 28 by a spring 3|. This tubular valve stem extends through a thickened portion 32 at the outer end of the valve body 26. At this point the valve body 26 is providedwith a bushing 33, in which the tubular valve stem 30 will snugly fit and permit it to be both rotated and moved axially therein. Extending radially through the thickened portion 32 of the valve body 26 and the bushing 33 there is a vent forming passageway 34 that is adapted to cooperate, as will hereinafter appear, with a vent aperture 35 formed at a properly located point through the tubular valve stem 30. Mounted upon and closing the outer end of the tubular valve stem 30 there is an operating push button 36 by means of which the tubular valve stem 30 may be moved axially against the action of the valve member biasing spring 3|.

With this last above described embodiment of my invention, it will be seen that by pressing inwardly upon the operating push button 36, it will be possible to move the valve member 29 into its valve opening position and at the same time open the vent forming passageway 34 to the interior of the tubular valve stem 30 and permit the entrance of air to the interior of the container from which fluid is being withdrawn. It will also be noted, since the vent aperture 35 comprises only a small opening in one side of the tubular valve stem 30, that by a slight rotationof the operating push button 36 it will be possible to move the valve member 29 into its-valve open position without establishing a venting communication with the atmosphere through the tubular valve stem 30.

From the above it will be seen that I have provided a novel vented valve, which, in addition to controlling the discharge of fluid from the container, will also control the admission of air to from the container will be admitted thereto and also provides against contamination of'the fluid when the valve is closed.

While I have, for the sake of clearness and in order to disclose my invention so that the same can be readily understood, described and illustrated specific devices and arrangements, I desire to have it understood that this invention is not limited to the specific means disclosed, but may be embodied in other ways that will suggest themselves to persons skilled in the art.
