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 inoperative 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 simplified 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 description 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.

Figure 3 is a front view of the faucet and valve in closed position.

Figure 4 is a longitudinal sectional View of the Valve faucet proper.

Figure 5 is a cross section on the line 5 5 of Figure 1.

There is illustrated a dispensing device generally indicated by the reference character Il consisting of a cylindrical barrel Il of any suitable diameter and length to meet the particular` requirements for a given size of container or drum.

In the present instance we will assume that the dispensing device is to be installed in the bunghole of a standard drum, a wall I2 of which is indicated in Figures 1 and 2. The barrel II is formed with an enlarged body portion I3 at one end having exterior screw threads formed thereon complemental to threads of the bung hole. In order that the barrel II may be securely engaged in the bung, a hexagonal or similarly shaped head I 4 is formed. The head I4 is 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 mounting of a plate I8, now to be described. The plate is in the form of a disk, of the same diameter as the ange i?, suitably apertured to receive 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 ange, as indicated 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 discharge port 3! inwardly of the head 26. At the end opposite the head 26 the bore 3i! is closed, substantially by a wall 32, ported as at 33. An inlet port 34 is provided, positioned in the same longitudinalv plane and upon the same side of the body as the port 3 I, the inlet port 34 being aligned with the port 22 of the barrel in the discharging position of the faucet and valve. Diametrically opposite the ports 3I and S4, and air vent 35 is formed opening upon a concentric passage 3S which opens upon the inner end of the body.

The vent 35 is so located that in the discharge position of the faucet and valve, air will be admitted therethrough and through the passage 36 into the interior of the drum,

A breather control plate 3l is mounted upon the wall 32, in the present instance, by means of headed pins 38. The plate 3'l'is freely mounted upon the pins so that the plate may be moved to control the port 33 and the passage 35'.

A pair of longitudinalslots 39' are formed upon the sides of the body 25, located medially thereof, 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 connected by a concentric slot 42'. The slot 40 is positioned on the body 25 so as to lie slightly outward 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 opposite 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' and 4| are of slightly greater depth and width than the lug 24, so as to readily accommodate the latter, and further should be in such ratio as to permit the threaded portion 28 of the head to engage the threads 28 of the recess l5. The threads should have a pitch so that the head will be fully seated upon a rotation of the body of 180 degrees.

To assemble the faucet-valve in the barrel, the slot 4l is presented to the lug so as to receive thelatter, and the body 25 is then moved inwardly of the barrel until the lug engages the concentric slot 4l). The faucet-valve is then given a clockwise rotation until the lug engages the end of the slot and a straight inward movement of the faucet-valve will cause the lug to engage in the longitudinal slot 39 and permit reciprocatory movements of the faucet-valve as will be required.

The discharging position of the faucet is shown in Figure 1 and in normal operation liquid will pass through the aligned ports 22, 3d, the bore 39 to the discharge outlet 3|. The degree of discharge of liquid may be regulated by the location of the port 34 with respect to the port 22. The closed position of the faucet-valve is shown in Figure 2, wherein the valve body has been rotated 180 degrees so as to present the discharge port 3l at an uppermost position with the

ports

22 and 34 out of alignment. It will also be seen that the

threads

23 and 29 are engaged to maintain the body in such position against accidental opening of the valve. inasmuch as the b ody is rotated only 180 degrees, it is necessary that the pitch of the threads 2B and 29 be suchk as to permit full seating of the head 23 within the recess i5, When it is desired to move the valve from a discharging position (Figure 1) to a closed position (Figure 2), the body member 25 is moved inwardly, the lug 24 guiding the body in its longitudinal path until it reaches the concentricslot 4G. At this time. the threads 28 are in position to engage the threads 28, and by rotating the body by means of the head 23 through 180 degrees, which is permitted by reason of the fact that the lug 24 is now in alignment with the slot dll', the head 2S will be fully engaged in the recess l5.

During discharge position of the valve (Figure l), air is admitted by way of the vent 35 and passage 36 into the interior of the drum by way of the breather port 23 or through the space 2l.

In the event that an unusual pressure or vacuum condition is required within the drum, the valve is withdrawn to discharge position and then rotated counterclockwise 180 degrees so as to present the arrow 42 tothe pressure indication point 43. The port 34 is thus moved to a closed position and rotation of the valve will have aligned the lug 24 with a slot 33 on the opposite side of the body 25. The valve-faucet may now be reciprocated inwardly and outwardly. On the inward stroke the plate 31 will close the port 33 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. Passage of air in this manner obviates the need for special vent valves in the drum to insure proper ow 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.

While a preferred construction of the valvefaucet has been shown and described, this is by way of illustration only, and I consider as my own all such modifications in construction as fairly fall within the scope of the appended claims.
