CHARLES F. TERNEY, OF BUFFALO, NEW YORK.

BARREL-VALVE.

Specicaton of Letters Patent.

Patented Oct. 26, 1909.

Application led November 13, 1908. Serial No.462,399.

To all whom t't may concern:

Be it known that I, CHARLES F. TERNEY, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented a new and useful Im: provement in Barrel-Valves, of which the following is a specification.

This invention relates to a valve or bung for tapping beer or other liquids from a barrel by air pressure;

The object of this invention is to produce a valve of this character which is simple and inexpensive in construction and reliable in operation, which will securely close the barrel when the tapping rod or pipe is wit-hdrawn therefrom and which can be readily dismembered and assembled for cleaning or repairing.

In the accompanying drawings consisting of 2 sheets: Figure 1 is a vertical longitudinal section of my improved valve in connection with a tap showing the parts in the position which they occupy when the valve is opened and the tapping rod is pushed into the barrel. Fig. 2 is a vertical transverse section at right angles to Fig. 1 and taken on line 2-2 in that figure. Fig. 3 is a vertical section showing the bushing in the same position as that indicated in Fig. 1 but the tap, plug and connecting parts turned into a position corresponding to Fig. 2, which position the parts occupy when the valve is closed. Fig. 4 is a bottom plan view of the tap. Fig. 5 is a top plan view of the bushing and the head of the plug, the latter being in the position which it occupies when the valve is closed and the tap is removed therefrom. Fig. 6 is a view similar to Fig. 5 with the head of the plug removed. Fig. 7 is a the plug. Fig. 8 is a vertical longitudinal section of the bushing with the plug and connecting parts removed therefrom.

Similar letters of reference indicate corresponding parts throughout the several views.

A represents the bushing of the valve or bung which is preferably of circular form and provided on its periphery with a screw thread a whereby the same is secured within an opening in the head of the barrel and also provided at its inner or front end with a head B having a port or opening b on one side of its center. On the outer or rear side of the head around its port the same is raised slightly, forming a valve seat b1, as shown in Figs. 1, 3 and 8.

bottom plan view of the head of l/Vithin the front part of the bore of the bushing the same is provided with an internal screw thread c which preferably trends toward the left and within the outer or rear part of its bore the bushing is provided on diametrically opposite sides with tightening ribs d, d the front or inner sides @Z1 of which are inclined, as shown in Fig. 8. The ribs d are arranged outside or beyond the diameter of the screw thread c of the bushing.

E represents the plug whereby the port in the head ofthe bushing is opened and closed. The plug is provided with an external screw thread e which engages with the internal screw thread of the bushing.

In one part of the screw plug at the side of its center the same is provided with an opening f which is arranged parallel to the axis thereof and on another part of the screw plug at the side of its center the same is provided with a stopper or gate Gr. Upon turning the screw plug toward the right the same is moved axially -outward or away from the head ofthe bushing by the screw connection between these parts and the opening in the plug is brought into alinement with the port of the bushing head, while upon turning the screw plug toward the left the same will move axially inward toward the head. of the bushing and the stopper is caused to engage with the seat around the outer end of the port Z) and close the same. Owing to the screw thread connection between the plug and the bushing, the stopper engages with the valve seat only during the last part of the turning movement of the plug toward the left, and upon turning the screw plug toward the right the stopper recedes from the valve seat during the rst part of this movement, thereby enabling the valve to be operated very easily andl avoiding undue wear on the same.

The stopper may be constructed of rubber or any other suitable material and secured to the plug in various ways. As shown in the drawings, the same is constructed in the form of a flat plate which is provided on its outer or rear lside with a dove tail po-rtion g which engages with a correspondingly formed seat h extending radially inward from the periphery of the plug on the front side thereof, as shown in Figs. 1, 2,' 8 and 6. In order to prevent the stopper fromA being engaged with the valve seat with undue pressure upon closing thevalve, ythe front or inner side of the plug is provided with a stop or projection z' which is adapted to engage with a bearing surface or seat l on the rear side of the bushing head adjacent to its port, as shown in Fig. 3.

J represents a head or cover plate secured to the outer end of the plug and provided on diametrically opposite sides of its periphery with laterally projecting or peripheral lugs y', j which are adapted to engage wit-h the ribs Z of the bushing for preventing the plug from being removed from the bushing. The plug head is provided on one side of its center with an opening jl which is in line with the opening f of the plug. On its front side the plug head is provided with forwardly or inwardly projecting lugs K, K which engage with notches or seats Z, Z at the rear end of the plug, thereby interlocking the plug and its head and compelling the same to turn together. The bushing and its head are secured against displacement relatively to each other in the direction of the axes of the same by means of screws m passing through the head from the outer side thereof and entering threaded openings in the rear end of the plug. In assembling the parts, the plug is first screwed in the bushing until its outer or rear end is separated a suitable distance from the front side of the ribs of the bushing. The diameter of the coperating threads of the bushi` and plug is less than the diameter at the inner edge or bore of the ribs of the bushing. After the screw plug has been thus introduced in the bushing, the plug head is passed axially into the bushing while the lugs of the head are in alinement with the spaces between the opposing end of the ribs of the bushing and then the plug head is interlocked with the plug by engaging its front lugs with the recesses of the plug and is secured to the latter by means of the screws m. After the plug head has been thus applied to the plug the latter cannot be fully unscrewed from the bushing, inasmuch as the peripheral lugs y', y' of its head will strike the internal ribs CZ of the bushing.

N represents the tubular body of the tap which is arranged eccentrically on the rear or outer side of a coupling head O and which is provided with a laterally projecting nozzle p. The body of the tap is adapted to receive the tapping tube or pipe Q whereby the liquid is to be withdrawn from the barrel and the nozzle is adapted to receive a tube or conduit through which compressed air is delivered into the barrel for forcing or expelling the liquid therein through the tapping rod. The coupling head O is provided on its front side with a tubular shank r which is adapted to enter the outer or rear end of the bushing and around this bushing the coupling head is provided on its front side with a packing ring r1 of rubber or other suitable material which is adapted to engage with the outer end of the bushing and form a tight joint between the same and the coupling head while the tapping device is in operation.

Means are provided for compelling the tap to turn with the plug for opening and closing the valve and also detachably connecting the same with the bushing. The preferred means for this purpose as shown in the drawings consist of a pair of seats or recesses s, 8 formed within the bore of the shank r and adapted to receive outwardly projecting lugs s1, s1 formed on the outer side of the plug head and two coupling lugs t, t projecting laterally from diametrically opposite sides of the periphery of the shank and adapted to cooperate with the tightening ribs CZ of the bushing. In attaching the tap to the plug and bushing, the tap is first placed with its laterally projecting lugs t, t in alinenient with the spaces between the ribs CZ of the bushing and then moved forwardly so that its shank enters the outer end of the bushing and its laterally projecting lugs t, t pass through the spaces between the ribs and its recesses s, s receive the coupling lugs s1, s1 of the plug head. After the tap has been thus applied to the bushing and plug it is turned toward the right, thereby causing the laterally projecting lugs t, t of the shank to engage with the inclined front sides of the ribs Z of the bushing and cause the head of the tap and the packing r1 to be drawn firmly against the outer end of the bushing, thereby forming a tight connection between these parts. l/Vhile thus turning' the tap for connecting the same with the bushing, the plug is also turned by means of the interlocking lugs and recesses s, s1, thereby causing the stopper of the plug to be moved away from the port of the bushing head and the opening of the plug and plug head to be brought in alinement with the port of the bushing head. In the coupled position of the tap and plug, the body of the tap is in line with the openings of the plug and plug head, so that when the valve is opened, the port of the bushing head, the openings of the plug and plug` head, and the tubular body of the tap are all in alinement.

Before turning the tap for opening the valve, the tapping pipe or rod Q is pushed part way through the stuiiing box g at the outer end of the tap and after the latter has been fully turned toward'the right together with a plug, the tapping rod is pushed inwardly through the openings of the plug and plug head, the port of thebushing and into the barrel for withdrawing the liquid therefrom.

Vhen disconnecting the tapping device from the barrel, the tapping rod is first withdrawn from the barrel and into the body of the tap and then the latter is turned toward the left until the tightening lugs on its shank are disengaged from the inclined inner sides of thc bushing ribs and brought into alinement with the spaces between the same. Thereafter the tap may be withdrawn axially from the bushing and the plug head. Vhile thus turning the tap toward the lett for disengaging the same from the plug, the latter is also turnedkin the same direction for bringing its stopper over the valve seat of the bushing and closing the valve.

It will be noted that in the act of attaching the coupling` to the bushing the valve will be opened and that these parts can not be again uncoupled until the valve has been closed.
