BUNG FOR BARRELS, 8w. N0.-248,347. Patented Oct. 18,1881.

BUNG FOR BARRELS, 84c.

SPECIFICATION forming part of Letters Patent No. 248,347, dated October 18, 1881.

Application filed March 28, 1881. (No model.)

To all whom it may concern:

Be it known that I, TITUS POWERS, of the city and county of New York, State of New York, have invented a new and useful Improve inentin Bungs forBarrels, of which the following is a specification, reference being bad to the accompanying drawings, forming part of the same, in which Figure l is a plan or upper-face view of a bung containing my invention. Fig. 2 is a central longitudinal sectional view of the same. Fig. 3 is a similar sectional .view of the casing of the same, with the central plug reversed. Fig. 4 is an external side view of said plug. Fig. 5 is a top view of the same. Fig. 6 is a face view of the lower end of said plug. Fig. 7 is a view of the screw-up valve; and Fig. 8 is a section of said plug, cut on the line a 00, Fig. 4.

My invention relates to a hung provided with a vent that is controlled by a valve, which permits the admission of air into the cask to which it is applied and prevents its escape therefrom.

My bung consists of four principal parts-- viz., first, the case or bushing fitted to be secured tightly in the bung-hole of the cask; second, a main plug fitted into said case and forming an air-tight joint therewith, and removable at pleasure; third, a vent-plug within the main plug; fourth, valves connected with the vent-plugfor controlling the vent, the same being a screw-up valve at the lower end of said ventplug, the stem of which extends through the plug, and the upper end being provided with a screw-thread, and a broad-faced nut, which constitutes a disk-valve that controls the upper end of the vent-hole in the plug, and also a flexible automatic valve in the said vent-plug intermediate with the said screw-up valve and said disk-valve.

A is a case or bushing provided with a screwthread on its outer surface, and preferably made tapering, adapted to be screwed tightly into the bung-hole of a barrel or keg. At the upper end are two segments, a a, of an in wardly-projecting annular flange. At the lower end of this case there is an inwardly-projecting flange, b, that forms a seat for the main plug B, which is itself a shell or case provided with a perforated diaphragm, c, and a shoulder, d,

that sets down upon the flange b, and, with suitable packing, 6, forms a tight joint therewith when the plug is pressed forcibly upon it. At the the upper end of said plug are laterally-1: rojecting lugsff with inclined upper surfaces, as seen in Fig. 4, adapted to pass down between the segments a a when the plug is insertedjn bushing A, and to pass under the segments when the plug is turned, and thus lock the plug firmly down on the packing e.

O is a screw-up valve, the stem at of which passes up through a central opening in the di-v aphragm c, a screw-thread being cut on the upper end that is provided with a nut, 9, that has a broad flange, b, which rests on the diaphragm c and constitutes a disk-valve thereon. A small aperture, t', is made through the said diaphragm, and the said flange his provided with a corresponding aperture, 45, the two apertures, where they coincide, constituting a vent-opening through the'said plug, such "out being closed by turning the flange It so that the two apertures do not coincide. The lower end of the bushing A constitutes the seat of the valve 0, an air-tight joint being formed between them by suitable packing,j. The motion of the flange h is limited by a stop-pin in, fixed in the interior of the bushing A, near its upper end, and 'a projecting segment, I, on the perimeter of flange h. These parts are so made and proportioned that when the nut g is turned so thatoneend ofsaid segment lstrikes against the pin k the said nut is screwed down, thereby drawing up valve 0 and closing the joint atj, and at the same time closing the aperture t', and when turned so that the opposite end of said segment strikes against said stop-pin the vent i is opened and the nut g is.run back on the stem on, so thatthe valve 0 drops down, thus opening thejoint atj.

The screw-up valve 0 and its stem at are prevented from turning in the main plug B,

with the nut g, by means of the notches s in the central opening, 75, in the main plug B, as seen in Fig. 5, and radial projections s on the base of the stem m, as seen in Figs. 6 and 7,

that fit into said notches.

n is a flexible valve, preferably a disk of rubber having a central opening, permitting it to be put onto the stem of valve 0 and be held in an annular groove, 0, Fig. 7. An annular projection,s, ontheunder side of the diaphragm 0, forms a seat for this flexible valve, so that pressure on the upper side will throw it down onto the upper face of valve 0, and thus permit air to pass down through the jointj, when that joint is open.

Fig. 8 shows several recesses, 12, made in the inner face of the plug 13, to receive a suitablyformed winch to be used in turning'said plug in the bushing A.

The application and operation of this bun g are as follows: A bung-hole of suitable size being made in the barrel or keg, the bushing A is screwed into it, so as to form an air-tight joint. The plug B not being yet inserted the barrel may be filled through the bushing. Then the plug is inserted and secured, and the nutg, with the disk h, is turned so as to draw up the valve 0 and close the joint j, and also close the vent 1'. Then, when the contents of the barrel are being drawn off and a vent is required, the nut g is turned back, so as to allow the valve G to fall away from its seat and at the same time open the vent-hole i, thus permitting air to pass through the said vent-hole and joint Then, if the pressure ofair or gas in the barrel overbalances the pressure of the external atmosphere, the flexible valve or will be closed by such interior pressure and the cs 0 cape of gas prevented.

The bung which Ihave described is an improvement on that for which United States Letters Patent No. 232,903 were granted to me October 5, 1880.

What I claim as new, and desire to secure by Letters Patent, is-

1. A hung in which are the bushing A, the plugB,provided with thediaphragmc,provided with a vent-hole, i, the valve (J, the stem m of which is provided with a screw-thread, the nut 9, having flange h, provided with a vent-hole, i, and the flexible valve n, all constructed and combined to operate as and for the purpose described.

2. The combination, in a hung, of the plug B, having the vented diaphragm a, valve G, nut 9. having the vented flange h, provided with the segmental projection l, and the stoppin it, all constructed and arranged to operate as and for the purpose described.

In witness whereof I have hereunto set my hand, March 7,1881.
