Woock, Auburn, Calif. y Application March 15, 1943, Serial No. 479,280 4 Claims. 1 This invention relates to a drum valve and faucet especially adapted to use in dispensing liquids from closed containers, such as drums, and it consists in the constructions, arrangements and combinations herein described and claimed. It is a particular object of the invention to provide a valve in which an automatic control of the vacuum and air pressure conditions within a closed container may be readily controlled and eliminating the need Jfor the usual vent valve ordinarily required in containers of the kind specified, in order that a liquid may be dispensed from the container or drum. It is also an object of the invention to provide a dispensing valve in which the dispensing faucet or spigot may be fully housed, when in inopera tive position, so that it lies susbtantially flush with the wall of the drum or container, avoiding the possibility of being struck, which eventually might cause a leaky valve. It is a still further object of the invention to provide a dispensing valve and faucet of simpli fied construction, of few moving parts, and which may be wholly constructed from plastics. Additional objects, advantages and features of invention will be apparent from the following de scription considered in conjunction with the ac“ companying drawing, wherein Figure l is a longitudinal sectional View through a valve and faucet constructed in accordance with the invention, in dispensing position. Figure 2 is a similar View of the device in closed position. (o1. 222-400) ` 2 formed with a recess f5, concentric with the bore I5 of the cylinder, the recess being interiorly threaded for a purpose to be explained. The opposite end of the barrel is open and is provided with an annular iiange Il for mount ing of a plate I8, now to be described. The plate is in the form of a disk, of the same diam eter as the ñange i?, suitably apertured to re ceive machine -‘bolts I9 the latter being threadedly engaged in apertures in the flange Il; a sleeve Eil is arranged on the bolts extended through the apertures of the plate so as to maintain the plate in free» sliding relation with the ñange, as indi cated at 2|. y As shown in Figures 1 and 2, the lower side of the barrel II is formed with an inlet opening 22, and upon the opposite or upper side a breather port 23 is formed, which is located approximately intermediate the length of the barrel. Upon the bore IS of the cylinder an inwardly projecting lug 2li is formed which functions for the' guidance and retention of a combined. valve and faucet, now to be described. As shown in Figure 4, the lvalve and faucet is formed as a cylindrical body 25 of a length less thanv the barrel II and of a diameter to snugly yet slidably and rotatably fit within the barrel, The body includes an operatingfhead 25 suitably formed with a hand grip 2l and at the base of the head threads 28 are formed, complemental to the threads 2S of the recess i5. A longitudinally extending bore Si! is formed in the body of substantial diameter, having a dis Figure 3 is a front view of the faucet and valve charge port 3! inwardly of the head 26.

The head I4 is 55 the sides of the body 25, located medially there f. , I 2,405,681 3 of, and in opposed relation. The inner ends of the slots 39 are connected by a concentric slot 40 while the outer ends of the slots 39 are con nected by a concentric slot 42'. The slot 40 is positioned on the body 25 so as to lie slightly out ward of the port 34 but at the opposite side of Vthe body; while the slot 40’ is formed upon the body 25 in opposed relation to the slot 4B and iS positioned inwardly of the port 3 l . At a point op posite the inlet port 34, a slot 4l is formed in the body extending longitudinally from the slot 40 to the end of the body. The slots 39, 4t, 4B' 4 and passage 36, creating a pressure on liquid in the space 44 of the barrel. On the outward stroke, the plate 37 will be unseated and air is admitted to the chamber 44 by way of the vent 33 and passage 36, air also passing through port 33 into the chamber 44, from whence air may pass into the drum by way of the port 23. Pas sage of air in this manner obviates the need for special vent valves in the drum to insure proper ñow of liquid through the faucet. The operation may be continued until the required pressure has been attained, which will vary, depending upon the viscosity of the liquids to be dispensed. and 4| are of slightly greater depth and width While a preferred construction of the valve than the lug 24, so as to readily accommodate the latter, and further should be in such ratio as 15 faucet has been shown and described, this is by way of illustration only, and I consider as my to permit the threaded portion 28 of the head to engage the threads 28 of the recess l5.
