SPECIFICATION forming part of Letters Patent No; 409,713, dated August 2'7, 1889.
Application filed June 1, 1889.
T0 aZZ whom it mag concern.-
Be it known that I, lVILLIAM H. SUNDAY, a citizen of the United States, residing at Scranton, in the county of Lackawanna and State of Pennsylvania, have invented certain new and useful Improvements in Bungs for Barrels, Kegs, or other Vessels; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a partof this specification.
The special object of my invention is to make an elastic bung for barrels, kegs, or other vessels, as hereinafter fully described.
Figure 1 of the drawings is an elevation in perspective of my elastic valve provided with a central core. Fig. 2 is a vertical section on dotted line 00 0c of Fig. 1, showing it in connection with the bush; and Fig. 3 is abottom view of the bush.
In the drawings, A represents part of a bar rel, in which is secured the bush B.
G is my elastic bung, tapering downwardly and fitting the taper a of the bush B. The for- Th e Serial No. 312,851. (No model.)
arms (1' (Z pass down through the vertical grooves a a, and are turned against the cams a a so as to lock the elastic bung B-perfectly air-tight.
The air-channel (Z is provided with a valve 61 which shuts out all air until a faucet or some other outlet is opened, when air is admitted, so as to allow the liquid to flow freely at the outlet.
A light spring may be used to hold up the valve (Z so that as soon as a vacuum is produced by drawing out any of the liquid in the barrel the valve will open and admit air.
Having thus described all that is necessary to a full understanding of my inventiomwhat I claim as new, and desire to protect by Letters Patent, is
A doWnWardly-tapering elastic bu ng C, combined with a bush downwardly tapering on the inside and having the opposite vertical grooves a a, and provided with the cams a a and the core D, having wrench-arms (Z (Z at the top and arms cl d at the bottom,whicl1 are adapted to pass through the grooves a a and engage the cams a a substantially as and for the purpose set forth.
In testimony whereof I affix my signature in presence of two witnesses.
