signorto Manenti Ho Co tio ldingr rpora n 'My present invention relates to a tap valve for withdrawing liquid from an unvented container,

and more particularly to an improvedvalve meansl for a vented tap of the character disclosed in my copending4 application for Letters Patent Serial Number 661,233,- filed March 17, 1933.

An object l.of my invention is to provide a new and novel form of ball valve for a dispensing' tap or other fluid conduit.

Another object of my invention is to provide a new and improved valve means for a tap having a controlledvent.

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 toge er with the accompanying drawing wherein th is shown, by way of illustration and not of limi tion, a preferred embodiment thereof. g

In the drawing; Figure 1 is a perspective view of a tap constructedinv accordance with my invention,

Figure 2 is' alongitudinal sectional view oi the tap illustrated in Figure 1, showing the position of the parts whenrthe tap valve is open,

Figure 3 ils a view similar to Figure 2, showing the position of the parts when the tap valve is closed,

Figurek 4 is a transverse sectional view taken,

4 tion for Letters Patent. 'Ihe tap illustrated has abody portion 10 with a vent opening 11 in its top and a spout`12 at its lower side. At the base of thebody portion 10 there is aflange 13 which A is adapted to engage a mounting gasket, and beyond theange 13 the tap has acutter 14 and a threadedportion 15, by means of which it can be attached to a metallic container.l These latter features are fully described in my copending ap- :nlication and form no part of the present invenion. y

Upon referring to Figures 2 and 3 of the draw- "ing, it willbeseen that thebody portion 10 has an A inwardly taperingbore 16, into which a tapered valve carrying and operatingmember 17 projects. The valve carrying and operating,member 17 has a handle 18r by means of which it can be rotated and it is held in thebody portion 10 by asnap ring 19. lA. packinggasket 20 is .interposed'between the end of thebody portion 10 and aange 21 upon themember 17,-for the ing the outer-end of the tap.

purpose of seal- A The valve carrying andoperatingmember 17 has aport 22 that is adapted to align with thespout 12 when themember 17 is in its open position, and Vdirectly opposite theport 22 it has apocket 23, into which a vent controllingball valve 24 may repose when themember 17 is in its closed position.vThe ball valve 26 is located in anopening 27 in the' side of themember 17 and is adapted to roll into and out ofengagement 'with avalve seat 28, of rubber or the like, mounted at the inner end of the spout 12.V As shown, thevalve seat 28 is recessed in the end of alining tube 29 that is pressed into thespout 12.

Upon referring to VFigures 4 and 5 of the drawing, it will be seen that the valve carrying and operatingmember 17 has aneccentric groove 30 which extends in one direction from-thepocket 23 and partially around its outer surface. This groove30, because of its eccentricityQ/,fnioves theball valve 24 into andvout of sealing engagement with the vent opening 11, as the valve carrying andoperating member 17 is turned to close and/or open the tap.

Upon referring to Figure 6 of the drawing, it will be seen that themember 17 also has a longi- `tudinally extendinggroove 31 which terminates at thepocket 23. The purpose of thegroove 31 is to facilitate an' assembly of the tap. When assembling the tap, thebody portion 10 is'held with the spout 12 'extending upward and theball valve 24 is then placed in the body portion adjacent the vent opening 11. The helical spring can now be placed in the valve carrying and conf trolling member 17with theball valve 26 in the opening 27 at its end. After the latter parts ofv the tap have been assembled together, as above, the valve carrying andoperating member 17 can be inserted into thebody portion 10"by holding theball valve 26 with the thumb so as to compress thehelical spring 25, as shown in Figure 4 of the drawing. As themember 17 is inserted into the body portion'io, thegroove 31 will provide a clearance for 'the-ball valve 24. When themember 17 has been moved 'into its final posi- 'metallic container 33,. into which the threaded portion of the tap has been inserted, it will be evident that when the valve carrying andoperating member 17 is in the'position shown, the contents of thecontainer 33 will be free 'to flow through theport 22 and out through thespout 12.

theball valve 24, adjacent the vent opening 11, will drop down into thepocket 23 and permit air to enter the container through the vent opening 11 and aconduit 34 leading therefrom and connecting with the interior of the container. In order to permit a complete draining of thecontainer 33, the threadedportion 15 of the tap is provided with anAopening 35 which will align with the inside surface of the container.

Now should the valve carrying and operatingmember 17 be rotated into its "closed position,

. as shown in Figure 3 of the drawing, theball valve CII 24 will be raised by theeccentric groove 30 and close the vent opening l1 and theball valve 26 will be caused to roll into alignment with thespout 12, where it will engage thevalve seat 28 and close the tap. When `theball valve 26 is in this latter position, it will be held firmly against thevalveseat 28 by thehelical spring 25 and prevent an accidental valve opening movement of the valve carrying andoperating member 17.

While I have, for the 4sake of clearness and in order to disclose the invention so that it 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 specio means disclosed, but may be embodied in other ways that will suggest themselves to persons skilled in the art. It is believed that this invention is new and it is desired to claim it so that all changes as'come within the scope` of the appended claims are to be considered as part of this invention.
