` between the container and the spigot.

Another object is to provide a spigot of this character which, though simple in construction and economical to manufacture, is nevertheless rugged and durable as well as highly efficient in use.

Other objects and advantages reside in certain novel features of the construction, arrangement and combination of parts which will be hereinafter more fully described and particularly pointed out in the appended claims, reference being had to the accompanying drawing forming a part of this specification, and in which:

The gure is a view partly in longitudinal vertical section and partly in side elevation showing a metal spigot embodying my invention and applied to a beer barrel or the like.

Referring to the drawing, the numeral I desig- -nates a portion of a beer barrel which has a bung hole 2 closed originally by a plug or cork 3.

Before the barrel is tapped the plug 3 is irnperforate and provides a complete closure for the bung hole 2.

The spigot embodying the present invention is designated generally at S and has a tubular body 5 provided at one end with a spout or nozzle 6. To the other end of the body 5 a penetrating stem 'I is secured, preferably by having one of its ends threaded into the adjacent end of the body 5 as indicated at 8. The stem 'I is hollowed out for a portion of its length as indicated at I0 and at its outer end is provided with a tapered solid portion II provided with a spiral rib or screw I2. The extreme cuter end of the tapered portion II terminates in a bit or point I3. Adjacent the tapered end II, the penetrating stem is provided with lateral openings I4.

A valve designated generally at I5 is provided in the adjacent the vspout 8. Preferably, this valve is in the form of a rubber thimble I8 which has one end flanged and fastened against a shoulder I8 by means of a follower I9 and washer 20. Ordinarily the sleeve I5 closes the opening through the body portion 5 and prevents discharge of the beer or beverage through the spout 8. However, this valve thimble I5 may be (Cl. 22S-43) elongated or stretched to reduce its cross sectional area and allow the beer to flow past it and out through the spoutA 6. This may be accomplished by means of an operating knob 2i provided on the outer end of an operating rod 5 22, the latter being slidably fitted in an opening 28 provided therefor in the follower Il. 'I'he inner end of the rod 22 has an enlarged and rounded head 24, which is engageable with the inner closed end of the valve thimble and ef- 10 fective when the operating rod 22 is pushed inwardly to stretch the valve thimble, reduce its cross sectional area and allombeer to ow out through the spout 6.

. In order to permit of maintenance of pressure 15 onthe beer in the barrel, a nipple 25 may be integrally formed with'the bodyvportion 5 and extends upwardly therefrom. Into this nipple is threaded a coupling member. 28, the 'inner portion of which is reduced and connected to a check 20 valve 21 in the form of a slotted rubber thimble. The outer portion of the connection 26 is threaded as at 28 to adapt it to be connected to a tire pump or other source of pressure. When the device is not in use, a cap 30 may be threaded on 25 the coupling 26.

In applying the spigot S to a barrel or pony of beer the point I3 is pressed against the cord or plug 3 and the entire spigot is rotated to cause the penetrating stem 1 to pass through the cork 30 or plug 3 under the influence of its spiralrib or screw I2. This expands the portion of the plug penetrated and sets up a very tight seal between the plug, the penetrating stem and the wall ofthe bung hole 2. When the end II has passed 35 entirely through the bushing, a smooth portion of the penetrating stem may be pushed axially into the position shown in the drawing. In such position the annular flange 30 integral with the inner end of the body 5 overlaps the margin of the 40 bung hole in the manner shown. Beer may now be dispensed by holding a mug or glass under the spout 8 and pressing in on the knob 2 I.

While I have shown and described one construction in which the present invention may be 45 advantageously embodied, it is to be understood that this construction has been selected merely for the purposes of illustrationv or example and that various changes in the size, shape and arrangement of the parts may be made without 50 departing from the spirit of the invention or the scope of the subjoined claims.

The invention claimed is:

1. A metal spigot for use in tapping a container comprising a tubular body portion having a lat- 55 .e'nd. a valve in said body portion for controlling ow through said spout. an operating rod for said valve extending axially outward from the outer end of said body portion and operable to portion formed with a spiral rib and terminating in a pointed 'bit`andalso having between 'said piercing portion and the body of the spigot a cylindrical and externally smoothl hollow portion adapted to have sealing engagement with the closure of the buns Openins. the interior of the cylindrical portion communicating with the interior of the body portion, said cylindrical portion having transverse openings adjacent. its innerV end, in combination with means on the body portion .engageable with the container to prevent the closure from being pushed into the interior thereof. v

2. A metal spigot tor use in tapping a container by penetrating and having sealing engagement with avclosure of a bung hole thereof and comprising a tubular body portion having a laterally directed discharge spout adjacent its outer end, a valve in said body portion for controlling ilow through said spout, an operating rod for said valve extending axiailyoutwardly from the outer end ot said tubular body and operable to open the valve when pressed inwardly, a penetrating stem carried by the inner end oi the body and adapted to pierce the bung closure, and an annular flange on the inner end of said body portion and adapted to overlap the margin o! the buns 5 a laterally directed discharge spout adjacent its outer end, a valve in said body portion for controlling flow through said spout, an operating rod ior said valve extending axially outward from the outer end o! said body portion and operable 15 to open the valve, a penetrating stem carried by the inner endof the body and having at its inner end a tapered piercing portion formed with a spiral rib and terminating in a pointed bit and also having between said piercing portion andthe 20 body of the spigot a cylindrical and externally smooth hollow portion adapted to have sealing engagement with the closure of the bung opening, the interior of. the cylindrical portion communieating with the interior of the body portion, said 25 cylindrical portion having transverse openings adjacent its inner end for communication with the interior of the container.
