SPECIFICATION forming part f Letters Patent No. 693,314, dated 4February 11, 1902. l
Application filed November 16, 1,899. Serial No. 737.201. (No model.)
To all whom it may concern: y
Be it known that I, SIMON SCHLANGEN, a
resident of Chicago, in `the county of Cook and State of Illinois,` have invented certain new and useful Improvements in Bungs, of
which the following is a specification.
X My invention relates to bungs; and its object is to provide a bung automatic in operation-that is, one which is normally in closed 1o position and which must be opened whenit is desired to either insert or remove the bung from the bung-opening. Y
In the drawings, Figure l is a section, partly in elevation, of my bung and operating-key;
l Fig. 2, an elevation of such bung and a portion of the key; Fig. 3, a plan view of the bung, and Fig. 4 a plan of the top plate removed.
My bung may be used in connection with 2o either a bung-bushing or with a simple bungopening in the barrel,keg, orthe like, as de= sired, and in this application I have preferred to show it in the latter waythat is, in connection with the simple bung-opening-for thereason that with my bung a bushing lis not necessary, although it may-be used if it should be so desired. v l
The stave l of the .barrel is provided with a bung-hole2, preferably having its outer 3o and inner edges or faces beveledor reamed out; In generalvterms the bungcom'pris'es several'sections, whichl are movable with respect to each other, but which are normally held in compact relationship'by means of a 3 5 spring, and whichwhen in such compact form press an elastic member outwardlyto seat in the lower part of the bung-openin g, and thereby seal the same.y The tendencyof the bung is to automatically seat itself, and it can be 4o unseated and! removed only by. changing this compact relationship-that is, -by moving the parts on each other bypressure applied by a key or otherwise;
As shown, the bungk proper comprises the following parts: A shell 3 has a lower cylindrical portion and an annular portion 4, provided with a lip 5, extending over the rabbeted margin of a circular top plate 6. This plate has a cylindrical portion 7, received by 5o .an inner cup or cylinder 8, which is provided at its top margin with an annular flange 9, fitting, preferably, closely, but operatively, within the shell 3. A packing-nut 10, pressed or threaded into the cylinder 7, so as to be flush with the top plate, presses against suit- 5 5V able packing 11, resting in the bottom of such cylinder and through which passes a movable rod or plunger l2, having a head 13.
A shoulder 14 is riveted over onto a washer 15, so as to secure to the plunger the cylinder 6o 8, as'Well as an expanding-ring 16, having an inwardly-turned marginal iiange 17. .A coiled spring 18 lies in the annular space between the cylinders 3 and'8 and bears, respectively, against the flange Sand a ange 65 3 on the lower end of the cylinder 3. The tendency of this spring is to hold the cylinder 8 within the 'cylinder or shell-3 and also to hold the expanding ring or plate 16 up as closely as possible,' so that'all the parts will 7o be in compact relationship. A ring 19 eX- 'tends around-the outside of shell 3 and is provided with a liange 20.' The shell 3 is beaded at 2l and '22above and below this ring, so as to hold it in'proper position. The 75 l elastic member which I prefer to'use consists of acup or sack 23, having a thickened side portion 24 and thin end or bottom portion 25,and the same-may be secured to the ring-19 by means of a wire 26 or in any other suitable 8o manner. y The rubber mayhave a groove molded in it toreceive ange 20. This elastic member may consist of rubber and is preferably in the form of a sack, so as to seal all the parts of thebung, both to' prevent the (escape vofany 85 gas and also to protect the bung from the action of the contents of the barrel. VY hen the bung is innormal position, as shown, it automatically closes the bung-hole,inasmuch as the spring draws an expanding-ring against 9c the thickened `part of the rubber, throwing it outward against the beveled face or surface of the bung-hole, vso that not only is the hole sealed, but the bung is prevented from being withdrawn or blown out. pressure in the barrel the tighter the vfit. It is obvious that the bung will remain in this normally-closed condition until the plunger 12 is depressed or forced inward, so as to relieve the pressure of the expanding-ring .roo
The `greater the l against the elastic member, which will not only unseat the same, but permit the whole bung to be withdrawn.
The instrument or key for opening and withdrawing the bung contemplates in general terms a plunger for forcing the rod 12 inward. The key which I have shown as i suitable for this purpose comprises a body portion erstem 27, having a right-angled halfhandle 28. A half-handle 29, which with the other half-handle makes a handle complete in form when the parts are brought together is pivoted in the upper part of this stem and provided with a canrhead 30. This cam is adapted to bear against the plu nger 3l,movable longitudinally in the stem, and to depress it against the tension of spring 32. To accommodate and attach the remaining parts to be described,a pin 33 is screwedinto the lower end of the plunger,although it is obvious that the plunger itself may be extended and pointed for the same purpose of depressing the plunger 12 in the bung. The stem 27 has two downwardly-extending portions 34, which may rest on the top ot the bung when in position, as seen in Fig. 2. A plate 35 is screwed or otherwise secured to the stem 27, as shown in Fig. 1, and provided with downwardly-extendin g fingers or hooks 36, having a slot or notch 37, which hooks are adapted to be inserted through openings or slots 38, extending through the plates i and 6 of the bung. A plate 39 is secured to the pin 33 byY means of an integral nut 40 and is movable therewith. On its diagonal corners it has downwardly-proj ecting fingers 41, preferably having their lowerouter faces beveled,as at 42.
In operation the hooks 36 are first inserted in the slots' 38,and the handle 29 is thereupon swung closed upon the handle 28, which is made slightly shorter, so that the parts may be easily separated. This handle movement depresses iingers 41, whose beveled faces striking the ends oi' the slots on either side of the hooks act as wedges to partially rotate the entire key, thereby causing the slots 37 to engage the other ends of the slots 38 and locking the key and bung together. Simultaneously the pin 33 forces rod 12 inward and forces the expanding-ring away from engagement with the thickened portion of the rubber cup and also forces such ring against the lower portion of such cup, so that by pulling on the key the entire bung is free to be removed from the barrel. To insert the bung, the handle parts are first brought together to l1old the bung-sections in their open position, just as they were when withdrawn. The bung is then inserted in the bung-hole, and handle 29 is then raised to the position seen in Fig. 1, whereupon the spring will automatically expand the rubber cup, and the key is then free to be withdrawn, the tingers 4l being automatically withdrawn by means ot' the plunger 3l to allow the key to be manually partially turned to permit withdrawal of the hooks 36 from the slots. The function ot' the fingers Lil is to till the spacesl oit' the slots 3S that would otherwise remain open after the key had been partially turned to cause engagement between the bung and notches 37. The iilling of these spaces permits the key and bung to be securely locked together when the plunger 3l is depressed, so that the key may be turned in either direction for any purpose and as an accommodation to the operator. In case such fingers t1 were not used it would obviously be necessary to always turn the key and bung in the withdrawing operation in one and the same direction or otherwise the key would slip out of the bung. These fingers thus hold the notches 37 in engagement with the bung-body, and such engagement cannot be broken until the handle 29 is raised, so as to permit the plunger 31 to be restored to normal position.
By the use of my invention I provide a bung which obviates many of the objections to devices of this class. The automatic feature is particularly valuable,because it is impossible to force the elastic member too tightly or too loosely upon its seat. The pressure on the seat is determined by the tension of the spring, which may be of any desired tension. In the form of bungs in which members screw upon each other to close the bung there is danger of too tight seating and the destruction and inr y These objections, among jury of the parts. others, are avoided in my type of bung, which is automatic in action. Moreover, by the use of the peculiar construction of elastic member, which is in the form of a sack, the gas is prevented from escaping, because the same completely envelops the lower portion of the bung, so that the bung is protected from the contents of the barrel.
Although I have described more or less precise forms and details of construction, I do not intend to be understood as limiting 1nyself thereto, as I contemplate changes in form, the proportion of parts, and the substitution of equivalents as circumstances may suggest or render expedient and without departing from the spirit of my invention.
I claim- 1. A bung comprising a shell or casing, a
cylinder normally spring-pressed therein, a plate secured to the shell and having a cylindrical portion received by such cylinder and forming a guide and stuffing-box, an expanding ring or plate having an upwardly-turned flange, an elastic member secured at its top to the shell and normally expanded against the bung-openingandarod or plunger secured both to the cylinder and ring and passing through such stuffing-box.
