BUNG. No. 298,265. Patented May 6', 1884.
ANTON G. ANDERSON, OF CHICAGO, ILLINOIS.
SPECIFICATION forming part of Letters Patent No. 298,265, dated May 6, 1884.
Application filed January 11, 1584.
To all whom it may concern.-
Be it known that I, ANTON G. ANDERSON, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Bungs; and I do declare the following to be afull, clear, and exact description of the invention, such aswill 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 part of this specification.
My invention relates to bung-bushings for casks, barrels, 850., and has for its object a bung-bushing formed of metal and provided with an innerlining of wood, compressed wood, paperpulp, vulcanized fiber, or other suitable material, said inner lining being so secured to the bushing as to remain firm under any and all circumstances.
The invention relates more particularly to the manner in which thelining is firmly seated 'within and between the upper and lower flanges and against the inner surface of the bushing without breaking, crushing, weakening, or otherwise injuring the lining, which would be the case were it forced into the bushing through the upper flanges thereof. Again, when the lining is inserted into the bushing in the manner above set forthto wit, by forcing it through the upper flangesthe bung stopper or plug is liable, when pressed downward into the lining, to split the lining, inasmuch as the lining (when inserted into the bushing through the upper flanges) does not bear against the inner surface of the bushing, in which case the lining isliable to be split by the strain exerted upon it by the plug, and to thus cause leaks about said plug, as will be readily understood.
To obviate the above-named objections my invention has been made; and, as stated above, it consists in a lining so formed as to be inserted into a, bushing without breaking or crushing the outer surface of such lining; and it further consists in the means employed to firmly fix and secure the lining in the bushing, so that the outer surface thereof shall bear against the inner surface of thebushing, and thus prevent any strains (tending to split said (No model.)
lining) being exerted upon the bung-stopper of said lining. I
In the drawings, Figure 1 represents a top plan view of a bung-bushing provided with my improvement. Fig. 2 is a transverse'section view of my improvement in position in a cask-0r barrel. Fig. 8 is a top plan view of the lining and its ti ghtening-wedge. Fig. 4 is a top plan view of my bushing provided with my imprdvement, and having a portion of its upper inner flange cut away for the insertion of a wedge. Fig. 5 represents a top plan view of the lining, having ribs or projections on the sides of its tightening-wedge.
Similar letters of reference in the drawings denote like parts.
Referring to the drawings, A represents the metallic-bushing, having the usual tapering form and screw-threaded outer surface, and top and bottom flanges, a a a, and also with a V-shaped flange, a surrounding its inner surface at a point preferably equidistant from its top and bottom. 13 represents a lining formed of wood, paper-pulp, or vulcanized fiber pressed into shape.
structed as described may be easily inserted intd a bushing, inasmuch as it is only necessary to compress the lining, such compression being rendered possible by the cut-away portion of said lining; and it will be also readily seen that the outer surface of the lining will bear against the inner surface of the bushing when in position, and that the wedge b will, when driven down, prevent any displacement of said lining.
In Fig. 4.1 have shown a bushing provided with a cut-away portion, a", in its upper inner flange, for the easy insertion of the wedge b.
In Fig. 5 I have shown the sides of the wedge provided with ribs b b, that enter corresponding recesses in the sides I) of the lining B,
w'hereby is obtained an additional resistance to the withdrawal of the wedge; and in said Fi g. 5 I have shown an additional modification of the cutaway portion of the lining,such modification consisting of a straight cut or slit, b. As will be understood, the purpose of the cutaway portion of the lining is that said lining may be introduced easily into the bushing, such lining corresponding in diameter with the distance across the bushingupon theinner side thereof.
\Vhat I claim is 1. In abung-bushing, the combination of the metallic bushing A, provided with flanges a a a, and a ridge, a, with a lining formed of wood, or compressed wood, paper-pulp, or
