7 Claims.

My invention relates to improvements in combined faucets and air pumps for liquid containers, and the object of the invention is to incorporate a faucet and air pump into a single unit, in which the pump and faucet will be alternately operable and simultaneously inoperable to prevent leakage, in which the faucet, when secured in the container, can be tightened in any position desired in relation to the tap, which may be used in any depth of container, which can be sealed to render it impossible to remove the container contents without breaking the seal, and in which the pump, when the pump and spout are sealed in the closed position, coacts with a half cover to form a handle grip, and it consists essentially of the arrangement and construction of parts as -hereinafter more particularly explained.

Fig. 1 is a sectional elevation of my device taken through the pump.

Fig. 2 is a sectional view on line 2--2, Fig. 1.

Fig. 3 is a sectional plan view on line 3-3, Fig. 1 or 2.

Fig. 4 is a sectional view through the upper portion of a cask and showing my device in. ele- 5 vation.

Fig. 5 is a plan view of a cask showing my device on a reduced scale with the half cover broken away from the most part.

Figs. '7 and 8 illustrate a modified form of sealing means.

5 Fig. 9 is a sectional view of the lower end of the liquid discharge pipe showing the strainer sieve. Figs. 10, 11, and 12 indicate alternative structures for preventing the use of the spout as a handle and the consequent breaking of the same.

40 In the drawings like characters of reference indicate corresponding parts in each figure.

1 indicates a cask provided with the usual end head 2 having an orifice 3 in which is screwed a cylindrical bung 4 having an externally threaded 45 head 5 having a tapered lower face countersunk in the surface of the head 2 and a circular recess 5 in the upper face. 6 is a nut which is recessed on its lower face at 6 and internally threaded and provided with a central orifice 6. I is the 50 body of the faucet provided with a circular base 1 slightly thicker than the depth of the recess 5 so that its upper face is above the upper edge of the recess wall permitting of the base 1 being clamped between the top wall of the nut and the 55 base of the recess 5 8 is a transverse tapered orifice in the body I forming a seat for the valve plug 9. 8 is an air port extending from the orifice 8 to the bottom of the base l within the open centre of the bung 4 and 8 is an orifice also extending from the orifice 5 8 to the bottom of the base 1 and in which is secured the upper end of the liquid discharge pipe l9, passing through the open centre of the bung 4 into the liquid container such as the cask l and extending adjacent the bottom thereof. The 0 plug 9 is provided, at its outer or large .end, with a cylindrical enlargement l I forming an annular shoulder l bearing against the wall of the body 1 around the orifice 8.

The small end of the plug 9 projects from the 15 small end of the orifice 8 and is threaded as indicated at l2. I3 is a nut which is screwed onto the threaded portion l2 and l3 is a compression spring extending between the nut l3 and. the opposing wall of the body I to resiliently hold the 20 plug 9 from free rotation. is a boss extending from the periphery of the plug enlargement II. The boss is provided with an internally threaded orifice H 9 is a duct leading from the orifice l l and located, at its opposite end, in the periphery of the plug 9 at a point in circumferential alignment with the air port 8 9 is a liquid discharge duct extending from the periphery of the plug 9 in circumferential alignment with the adjacent end of the liquid discharge pipe l0. 9 is a'lateral extension of the orifice 9 extending centrally through the small end of the plug 9 and in which is secured the inner end of a spout I4.

It will thus be seen that there is an angle of 90 between the position of the port orifices 8 and 8 of the body and the normal position of the discharge end of the air duct 9 and also an angle of 90 between the normal position of the discharge end of the air duct 9 and the liquid 40 discharge orifice 9.

M is a pump base member having a reduced exteriorly threaded portion Hi having a central orifice l5, one end of which is enlarged at IS to receive a ball valve I6 coacting with a seat I6 at the inner end of the enlargement, the opposite end having a slightly burred edge to retain the ball therein. The opposite end of the orifice i5 is also enlarge-d at 15 to receive the tubular piston rod I! which is secured therein carrying a piston II I8 is a pump cylinder open at its inner end to slidably fit the reduced exterior portion I5 Within the cylinder is screwed. an inner head IB 55 having an orifice I 8 through which the piston rod ll slidably extends.

From the foregoing it will readily be seen that when the pump cylinder I8 is swung through 90 together with the spout M to a vertical position that the outer ends of the ducts 9 and 9 will travel down 90 so that the duct 9 registers with the upper end of the port 3 the duct 9 leading to the spout remaining closed. The pump is then operated to pump air into the top of the container over the liquid to produce a pressure thereon.

If it is desired to draw the liquid, the pump I8 is swung together with the spout a further 90 carrying the spout and duct 9 into position to register with the upper end of the discharge pipe ID at the same time carrying the duct 9 to a closed position. The liquid, by means of the air pressure previously created in the container, forces the liquid up the pipe l0 through the duct 9 and the spout M. The parts, during the liquid out-flow, assume the dotted position shown in Fig. enabling the discharged liquid to be received in a suitable receptacle. When the pump is swung back to the normal position shown in Fig. 1 both ducts 9 and 9 are in the closed position, the pump and spout being then in position ready for sealing.

i9 is a half cover formed preferably of sheet metal bearing at its edge against the rim of the container as shown in Figs. 4 and 5 and bearing also against the pump cylinder l8, the edge of the cover being curved downward at [9 to follow the contour of the pump cylinder.

To secure the cover in place, I provide a looped bracket 20 depending from the cover and a bracket 2| secured to the container head 2 and forming a tongue 22 engaging the bracket 20. 23 is an orifice adjacent the opposite end of the cover through which a stud 24 forming part of the valve body 1 projects. Around the orifice 23 the cover is depressed as indicated at 24 to provide room for a perforation 24 through which a sealing wire 25 extends without projecting above the rim 2 of the cask or container. 26 is a seal for sealing the ends of the wire 25.

The cover l9 not only protects the faucet and pump from injury, but prevents its operation by an unauthorized person and also serves in conjunction with the pump cylinder as a comfortable and strong hand grip for lifting the container from place to place.

In Figs. 7 and 8 I show an alternative form of sealing means. In these figures the'stud 24 is provided with a peripheral notch 26. 2'! is a plate pivoted at 28, an edge of the plate extending through the notch 26 after being sprung over the head of a rivet 29. A sealing wire 33 passes through a perforation 3i and a corresponding perforation formed in the cover l9.

The pipe I!) is formed of bendable material so that its length may be accommodated to any depth of cask by off-setting it as indicated in Fig. 4. The pipe is also provided with a sieve 32 to prevent any sediment or other foreign matter passing up the pipe with the liquid.

In Fig. 10 I have shown a modified form of spout connection which will allow of the spout being secured in a stationary position during pouring and at the same time prevent it being used as a handle for lifting the keg or container from place to place. If the spout was rigidly connected to the valve plug 9 as in Fig. 3, the operator might attempt to lift the can by carelessly gripping the spout and breaking it. To

avoid this result, I couple the spout 33 to the externally threaded discharge end of the valve plug 34.

35 is a nut screwed at one end upon the thread of the valve body and freely surrounding the spout at the opposite end. An internal shoulder 35 is formed between which and the end of the valve plug the annularly flanged end 33 of the spout 33 and a packing washer 35 is clamped forming a leak proof joint which will allow the spout to turn freely in the nut 35 so that no lifting strain can be put on it tending to break it off.

In Fig. 11 I show another modified form which achieves the same result as that of Fig. 10. In this form the spout 36 is made of flexible metal tubing secured to the discharge end 31 of the valve plug by welding or other suitable means.

In Fig. 12, if any lifting strain is exerted on the spout, it automatically separates from the valve plug. In this form the inner end of the spout is provided with a bayonet slot or slots 38 with which a corresponding pin 39 engages, the pin extending from the plug discharge end 40. Any upward lift on the free end of the spout engages the curved portion of the slot 38 with the pin 39 producing a cam action which forces the spout outward longitudinally from the discharge and clear of the pin 39.

In the forms shown in Figs. 10 and 11, the free end of the spout may be secured to the container so that it will remain in a stationary position and not move back and forth every time the device is operated to shut off the liquid and thereby make it more convenient to draw liquid from the container.

From this description it will be seen that I have devised a device, particularly adaptable to beer casks, in which a faucet and pressure pump are incorporated in one unit, in which it is ensured that when the port of one of the aforesaid devices is open for operation the port of the other device is positively closed or when both devices are not in operative position the ports of both devices are positively closed so that under nocondition can leakage occur, and in which the position of the spout is not controlled by the final position of the bung in the bung orifice so that the spout, in its inoperative position, will lie adjacent the inner side of the container rim and in the operative position will project, at its pouring end, over the container rim in position for pouring, and in which the parts may be effectually sealed from use, protected from injury when sealed and form a convenient means for lifting the container from place to place, and which may be readily adapted for use in any depth of cask or container.
