UNITED 'STATES- Patented March 15, 1904.

BUSHING.
SPECIFICATION forming part of Letters Patent No. 754,512, dated March 15, 1904.
Application iled February 26, 1903. Serial No. 145,252. (No model.)
To all whom t may concern:
Be it known that we, GUsTAvE STREHL and JOHN STREHL, citizens of the United States, and residents of La Crosse, in the county of La Orosse and State of Wisconsin, have made a certain new and useful Invention in Bushings; and we declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this-specification.
f Figure l is a sectional view showing the inner or bushing seat-section in position and the engaged .screw-wrench. Fig. 2 is a sectional view of theinner or bushing seat-section. Fig. 3 is a sectional view showing both parts of the bushing in position. Fig. 4: is a sectional view of the outer section. Fig. 5 is a side view of the inner or bushing seat-section.
, The invention relates to metal bushings for barrels, casks, and kegs, chiefly such as are used for holding ale or beer; and the invention consists in the novel construction and The object of the invention is to supply a strong and secure bushing which willpresent both on the outside and on the inside of the keg a smooth finish, the ianges requiring no projections, lugs, or recesses such as are made in ordinary metal bushings for use in screwing them into place.
In the accompanying drawings the letter a designates the wall of a barrel or keg having the bung-hole Z2, the surface of which is usuf ally made slightly tapering from the inside of the barrel-wall outward.
The metal bushing is made in two sectionsthe inner section or annular bushing-seat c and the outer section d. Each of these sections is provided with a smooth circular rimflange e at its exposed end, this flange being beveled or rounded o at its periphery. The outer bushing-section d is designed to screw into the inner bushing section or seat c and is therefore threaded around its exterior wall,
as at f, to engage the inner thread g of the bushing seat-section. The aperture t of this drawings.
bushing-section 0l is finished in the usual smooth tapering manner, as indicated in the The inner or bushing seat-section cis designed to engage the hole b in the wall of the barrel in a secure and tight manner and is provided with a rim-iiange which engages the interior of the barrel-wall around the hole. This iiange is usually provided with an under bevel or swell le, surrounding the neck or threaded portion in order that when screwed into the hole Z2 this part will be forced into the wood of the barrel-wall at the margin of the hole in such wise as to make a tight joint on the inside of the barrel. This bushing-seat is designed to be screwed into the hole b and is provided with an exterior sharp thread l of coarse pitch, which will forcibly engage the wall of the barrel-hole I) when turned with a suitable wrench and will form a secure connection with the wooden seat provided by this hole. Usually the turns of the sharp thread are separated by a broad thread bottom m, which is designed to receive and engage the fibers of the wood,` compressing the same without breaking them, so that the liability of leakage through the thread is reducedto a minimum. The interior of the bushing-seat c is provided w-ith a thread g to receive the thread of the outer Vbushing-section 0l. This thread usually terminates short of the outer edge p of the bushing-seat, and an interior annular rabbeted bearing or bevelshoulder s is provided in this end of ,the bushing-seat to receive the bearing ,of a screwwrench w, which is employed to turn the bushing-seat home. With this object in view the inner thread g, which is engaged by the holding-thread of the screw-wrench, has the same direction of inclination as the outer sharp thread Z, the latter, however, being, as hereinbefore indicated, a quick thread of coarse pitch. When the bushing-seat is properly engaged by the screw-wrench, it becomes practically solid therewith, and by its means the bushing-seat can be forcibly turned into the hole of the barrel, so as to engage the wooden bearing-wall of said hole in a secure and tight manner. The screw-wrench being removed, the outer bushing, having a line thread, can then be easily engaged with the bushing-seat.
Having described this invention, what we claim, and desire to secure by Letters Patent,-
derbeveled rim-fiange and inner underbeveled rim-ange being adapted to forcibly engage respectively the outer and inner walls of I5 a stave in which the bushing is seated, substantially as specified.
In testimony whereof we aflix our signatures in presence of two witnesses.
