TUBE-EXPANDER.

SPECIFICATION forming part of Letters Patent No 350,701, dates". October 12, 1886.

(Model.)

To all whom it may concern:

Be it known that we, WILLIAM Senonnnn- LEN, WILLIAM KLEIN, and AUGUsT SeHoEN- DELEN, ot' Davenport, in the county of Scott and State of Iowa, have invented a new and useful Improvement in Bang-Bush Expanders, of which the following is a specification, rei erence being had to the annexed drawings, forming a part thereof, in whichd Figure l is a longitudinal section. Fig. 2 is a transverse section taken on line x .fr in Fig. 1. Fig. 8 is a transverse section taken on line y yin Fig. l.. Fig. 4 is a transverse section of a part of a barrel-stave and t-he bung-bush in position in the stave.

Similar letters ot' reference indicate correspending parts in the different figures oi' the drawings.

The object of' our invention is to provide a simple and easlymanipulated tool for expanding bushes in the bung-holes of barrels and kegs, to retain the bushes in their place, and also to tighten them should they beeomeleaky after along use.

Our invention consists in the construction and arrangements of parts, as will be hereinafter fully described and claimed.

In the circular head A of the vyoke B is jonrnaled a sleeve, D, in the sides ot' which, at equally-distant points, are formed mortises a, for receiving and retaining rollers C. The sides ot' the mortises a are convergent, and the rollers C, being larger than the outer ends of the mortises, are retained loosely in the mor tises. An annular cap, E, secured to the end of the sleeve D, retains the rollers C in the mortises a. The end of the sleeve D, which projects into the yoke B, is provided with a eollar, F, between which and the circular end of the yoke are placed two washers, b and b, between which are placed convex rollers or balls c. The rollers@ retain their position bya hoop, d, which surrounds the series of rollers and the washers b and b. The end e of the yoke B is threaded internally to receive the threaded portion of a tapering spindle, G. The tapering spindle G extends through the sleeve D and passes between the rollers C, and the opposite end of the tapering spindle G receives a handle or wrench, H, by which itis turned.

Upon the threaded portion of the spindle G,

between the yokeB and thehandle H, is placed a Split internally-threaded ring, f, which may be tightened upon the threaded part of the spindle by a tangent screw, g, passingthrough one of a pair ot' ears formed on the split ring f and into the other ear.

Upon the Al'ace of-the circular end A ofthe yoke Bis formed a toothed flange, 7i, which engages the wood of the kegl or barrel in connection with which the expander isto be used, and prevents the yoke B from turning, while the spindle G is revolved by means ofthe handle H. The rollers C are slightly rounded at one end to facilitate their entrance into the bung-bush, and are made approximately hemispherical at the opposite end, to give the desired form to the bushes as they are forcedontward by the spindle.

In applying a bung-bush to a keg or barrel by means ot' our improved device, the bush is first inserted in the bung-hole ot' the keg or barrel, when the end of the sleeve D which projects beyond the lace ofthe circular end A ot the yoke B is inserted in the bush, as shown in Fig. l, the tapering spindle G having been withdrawn to allow the rollers C to retreat within the sleeve D, to admit of inserting it-in the bush. By pressing the yoke B forward againstthe stave in which the bush isinserted, the teeth L enter a short distance into the wood and offer resistance to the turning of the yoke B, permitting the spindle to be turned. The turning of the spindle G by virtue of the engagement ol' the threaded portion thereof with the internally-thrcaded end c ot' the yoke, advances it so that the portion passing between the rollers C is of a constantly-increasing diameter. By this means the rollers C are forced outward radially into contact with the bush, and. their Contact with the smooth surl'aee of the tapering portion of the spindle G causes them to revolve, while they are at the same time being forced outward laterally by the ta pering spindle. The rolling contact and the outward pressure of the rollers expands the inner end ol' the bush, as shown in Fig. Il. The ring F is adjusted upon the threaded portion of the spindle G, so as to limit the forward movement of thel spindle tothe amount necessary to expand the bush to the required extent. After the bush is expanded a reverse motion ICO of the handle withdraws the tapering part of the spindle from between the rollers more or less, allowing the rollers to retreat into the mort-ises a, when the expander may be removed from the keg` orbarrel and applied to another.

Bung-bushes may be inserted by means of our improved expander in a muchl more satisfactory way than by the usual method of screw'- ing them in, and when. a bush applied by means of our expander after long use or by accident becomes leaky, an application of the expander will enlarge it, so that it again becomes tight. Having thus described our invention, what We claimas new, and desire to secure by Letters Patent, is- 1. The combination, with the yoke B, having one end, e, provided with a longitudinal screw-threaded aperture, and a circular head, A, at the opposite end, provided with an aperture in alignment with that in the end e, of sleeve D, projecting through the head Aiuto the yoke and having a longitudinal aperture, the rollers C, aud an external shoulder abutting againstthe'outer face'of the head A, the collar F on the sleeve within the yoke, a ring, d, between 2 5 the collar F and the inner face of the head A, a series of loose rollers or balls, c, in the space between the collar, ring, and head, and the tapering shaft G, screw-threaded to engage the end e, substantially as set forth.

42. The combination, With the yoke B, having the circular head A at one end formed with a series of penetrating teeth on its forward edge, and the internally-threaded opposite end, e, of the shouldered sleeve D, extending through the circular head and provided with the rollers C and the retaining-collar F, and the tapering threaded shaft G, substantially as set forth.
