IMPROVEMENT IN ADJUSTABLE BARREL-HEADS.

tro ALL WHOM I'LMAY coNcERN:

'Be it known that we, PETER RINK and JAMES DOGHERTY, ofv Wertsvillc, in thecounty of Hunterdon, and State of New Jersey, have inventeda new and improved Mode of Securing Heads in Barrels; and we do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the.

art to make and use the same, reference being had tothe accompanying drawings, forming part of this specification. Y i

This invention consists in securing heads in barrels in such a. manner that the heads may be seeured'in barrels and removed therefrom without disturbing the hoops, and, in .case of shrinkagethe heads rendered capable of being expanded in order to insure a tight adjustment'of them in the barrels at all times.

In the accompanying sheet of drawings- Figre 1 is an outer side or face view ofi my invention.

Figure 2, a section of the' same, taken in the line :v 2:, iig. 1.

Figures 3 and L@sections ofthe same, taken respectively in the lines y y, z z.

Similar letters of reference indicate corresponding parts.

A represents one end of a barrel, and a the croz e, cut, as usual, in the inner surfaces ofthe stoves, (see iig. 2.)

B represents the head ofA the barrel, which may be constructed of two or more parts; Two parts, aX 6,`are shown in the drawings. I

The inner edges of these parts are not parallel with cach other, but oblique, to receive a taper wedge, C, the cdges of which are grooved longitudinally, as shown at c, to receive ,the inner edges of theparts: aX bofthe head, :is shown clearly in iig. 3.

D is a wedge, which may be considered as a continuationv of C, but instead of being grooved at its sides, is rebated, as shown at d, so as to form shoulders, e, on D,whieh bear or press on the uppersurfaecs of the two parts ax b of the head, (see iig. 4.).

The adjoining ends of the Wedges C D are rebatcd to form a dove-tail to reccivea key, E, which, when driven between C D, moves them longitudinally, and expands the two parts LX ofthe head, causing the latter to fit tightly in the crozej. and ifthe head should shrink, it may be erpanded by driving the key E still further between C D Y In order to loosen the' head,4 all thatis required is toj drive out the key E and remove C D. The parts a IJ of the head may then be taken out without any diiliculty, and without disturbing the hoops.

In order to prevent key E from slipping ont 4between the parts C D, a pin, f, is inserted through it, as shown in fig. 1.

We claim as new, and desire to secure by Letters Patent- The bevclled wedge O, grooved upon cach side to receive thc edges ofthe parts aX of the barrel-head, the short bcvelled wedge D, rebated upon its under side to fit between said parts, and rest upon their upper sides, both wedges secured together and tightened in thc head by means of the bevellcd wedge E. all constructed, arranged, `and operating as herein described, for the purpose specied.

PETER RINK, JAMES DOCHVERTY.
