AUTOMATIC STOP-VALVE BUNG.
SPECIFICATION forming part of Letters Patent No. 396,961, dated January 29, i889.
Application iiled May 2l, 1888. Serial No. 274,484I (No model.)
To all whom it may con/cern:
Be it known that I, LEVI F. SMITH, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Automatic St0p-Valve Brings; and I do hereby declare that the following' is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon', which form part of this specification, in whichd Figure l a central longitudinal section through my improved stop-valve bung. Fig. 2 is a face view of the same with the top removed. Fig. 3 is a detail sectional view showing the valve-depressing devices. Fig. 4 is a detail view of the keg. A
This invention is an improvement in valved bungs for tanks, and is especially designed for use on casks and barrels containing malt or fermenting liquors. Its objects are to pron vide a stop-valve bung and air-val ve combined, the stop valve being automatically closed by a spring and the air vent or valve being arranged in the stem of the stop-valve and adapted to be closed independently of the stop-valve.
Another object of the invention is to so constructthe bung that the valve can be held open while the cash or barrel is being iilled. This stop-valve bung is especially adapted for use on liquid-traiisporting vessels, as the vessel can be filled without removing the bung, and when filled can be hermetically closed; and to these ends the invention consists in the novel construction and arrangementof parts of the stop and air valve bung, as are hereinafter clearly described, illustrated in the drawings, and concisely stated in the claims hereto appended.
Referring to the drawings by letters,A represents a portion of a cash or vessel having' a bung-hole, in which is fitted an annular flanged bushing, B. This bushin is screw-threaded exteriorly for seeuringit in the bung-hole and interiorly for the engagement of my improved stop and air valve bung. The said bung has a cylindrical outer shell or casing, D, that is ianged at its outer end, as shown at d, and adjoining said flange the shell is exteriorly l screw-threaded for engaging the inner threads of bushing B, in which the valve is secured, l
as shown. The inner end of shell D has an annular interierlyscrewthreaded ring, E, which is connected to the main. body of the shell by legs or arms c c, as shown. The outer end of the shell is also screw-threaded intcriorly, as at f, and below said screwthreaded portion is a semi-annular partition, G, that is formed integral with the shell, leaving an opening, g, to one side thereof. Above or outside said partition G and threads f are formed a series of lugs, F Il, that project slightly inward from the wall. of the shell and which afford bearings for the engagement of a wrench, by which the stop-valve bung can be screwed into or out of place.
Below the partition G is an internal annular ring or projection, II, the inner edge of which is dressed to form a proper seat for the annular valve I. Valve I of such diameter as to move easily within the arms e, and dressed on its upper face to iit properly against its seat, as shown. The valve is mounted centrally on a stem, J, the outer end of which extends upward through an opening, fz', in partition G, which opening is in the axial line of the shell, and the rear end of the stem passes through an opening' in the center of a disk, K, which has a 4flange, 7o', preferably screw-threaded eXteriorly, by which said disk is engaged with the threaded ring E and sccured to the shell. The disk K may be secured to the ring E in any other suitable manner-such as by lugs and nuts; but I prefer employing the screw-thread, as the valve can then be more readily removed for re-dressing when it becomes worn. Said disk K is perforated. The stein and valve being' thus mounted and centered in shell D, the valve is rendered self-closing by means of a spiral conical spring, L, which is slipped on the valvestein between the valve and disk K, acting directly against the valve, as shown. The end of valve-stem J, that passes through partition G, is screwthreaded exteriorly and bored interiorly, as shown at j, said bore pass ing centrally through the stem from its outer end to a point below the valve. Said bore j is shouldered at m, above the valve, and above said shoulder is screw-threaded, as shown.
M is a screw-plug engaging the threaded portion of bore j, and of such length that wyhen screwed home its inner end, which is IOO properly dressed, will seat on shoulder on of the bore and close the latter.
N is an opening passing' laterally through the valve-stem comn'iunicating with bore ,7' above shoulder fut and the valve, and n is a similar opening communicating' with bore j below the valve, as shown.
The plug M is suitablyheaded to render its manipulation by the `Viiif g't-.i's easy.
O is a nut on the end of stem J, above partition G, which can be screwed down to lock the valve in its scat. The enlarged head of plug l\l prevents nut O being turned olii' the stem.
.'P is a slot in partiton G to one side of opening' t', and Q is a key or iiat bar of metal provided with opposite shoulders or notches, q q, on its side edges.
R is a metal cap having'an exteriorly-scrcwthreaded flange, r, which cap adapted to be engaged with threadsf of the shell and securely close the latter. Said cap may be provided with an external angular knob, S, by which it can be manilnilated, and said cap may be attached to the cask, shell, or bushing' by a chain, iff-desired, to prevent its being misplaced.
The manner of using the device is as follows: The bushing' 'B .is first secured in the bung-hole, then the bung' is screwed into said bushing, as shown, the valve being' kept closed by a spring, as is evident. If it is desired to fill the cask, the key Q is inserted through opening P in partition G and the valve depressed thereby. The key is then turned in opening P, and its notches (l q engage the lower edges of said slot, thereby locking-the key and holding the valve open. The tube through which the liquor is to be supplied to the barrel can then be passed through opening g and between two of the arms c intol the barrel. lVlien filled,the tube is withdrawn, key Q disengaged, and the valve immediately is automatically closed. Now if the cask is to be transported, nut is screwed down against partition G, absolutely locking the valve, so that it cannot become displaced, and cap R is put in place, protect ing the parts of the bung' from injury. lVhen it is desired to admit air to the cask without opening' valve I, the plug' M is partly unscrewed until it permits communication between opcning' N and bore j, and when this is done air can at once pass through said opening into the bore above the valve and from said bore through opening 'in into the cask below the valve.
llaving' described my invention, I clz'iinr- I. In a stop-valve bung, the combination of t-he cylindrical shell screw-threaded eXteriorly at one end and screw-threaded interiorly at both ends, and having' a semi-anmilar partition, an annularvalve-seat at one end, with a valve and a valve-stein carrying` sai d valve and having one end playing' through an opening' in said partition and screwthreaded, and having its other end playing through a screw-threaded disk in the lower end of the shell, a coiled spring for operatingl said valve, and the nut on the threaded end of the stem, all constructed and arranged substantially in the manner and for the pur pose described.
2. The combination of the shell, its valvescat, and valve having' a valve-stem bored longitudinally to establish communication through. the bung when the valve is closed, and having' lateral openings communicating with the bore at opposite sides of the valve, with a screw-plug', Wl, for closing said bore and cutting' off communication theretln'ough, substantially in the manner and 'for the purpose described.
3. The combination of a shell having an annular valve-seat, and a springactuated valve, with a valve-stem carrying said valve, having a central bore and openings communicating therewith on opposite sides of the valve, a screw-plug in the outer end of said stein t'or closing' communication through its bore, and a nut on said stem for regulating the movement of the valve, all. constructed and arranged substantially in the manner and for the Durpose described.
4.-. .In a stop-valve bung, the combination of the shell D, having internal partitions, G, an annular valve-seat below said partition, and an interiorly screw-threaded ring, E, at its opposite end, with the valve I, valve-stein J, nut O, disk K, exteriorly screw-threaded, and spring' Il, all constructed and arranged substantially in the manner and lfor the purpose described.
5. The herein-described stop-valve bung', consisting of a cylindrical eXtcriorly-screwthreaded shell formed with a transverse perforated partition near its outer end, and an annular val vc-seat at the inner side of said partition, in combination with a valve-stem, J carrying a valve, I, and playing' through a central opening' in said partition and through an opening' in a disk, K, secured in the inner end of the shell, the conical spring' controlling' said valve, and the setting-nut O on the end of the valve-stem outside the said partition, substantially as and for the purpose set forth.
(3. The combination of the flanged eXteriorly and interiorly screw-threaded bushing B with the stop-valve bring' having' an exteriorly-threaded portion engaging' said bushing', and a perforated partition, G, valveseat H, a spring actuated valve, I, its stem J, having bore and openings N n., the nut O, and plug' M, and key Q, all constructed and arranged to operate as and for the purpose described.
In testimony that I claim the foregoing' as my own I affix my signature in presence of two witnesses.
