UNTTED STATES PATENT JOSHUA MERRILL, OF BOSTON, MASSACHUSETTS.

IMPROVEMENT IN CASKS, BARRELS, AND KEGS.

Specification forming part of Letters Patent No. 58,451, dated October 2, 1866.

To all whom it may concern:

Be it known that I, JOSHUA MERRILL, ofthe city ot' Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Gasks, Barrels, and Kegs suitable for Heldin g and Transporting Liquids 5 and I do hereby declare that the following is a full and correct description thereof, reference being had 'to the annexed drawings, and to the letters ot' reference thereon.

My said invention consists of certain improvements upon an improved cask, barrel, or keg, having its joints ton gued and grooved and cemented, for which Letters Patent of the United States were granted to me, bearing date the 29th day of May, A. D. 1866.

First, in an improved cask, barrel, or keg suitable for holding and transporting liquids, A

having the joints of the staves and heads (when the head is of more than one piece) made with two or more tongues and grooves to each joint, in contradistinction to the single tongue-and-groove joints in the patent above referred to.

Second,in combining,with the tongued-andgrooved joints of cask, barrel, or keg made with two 0r more tongues and grooves to each joint, a coa-tin g or stung of glue or similar gelatinous cement, applied before the cask is set up, whereby the joints are rml y cemented by a cement suitable to resist petroleums, alcohol, and similar fluids that are resisted by glue and similar gelatinons substances.

Third, in combining', with the tongued and grooved joints of a cask, barrel, or keg made with two or more tongues and grooves to each joint, a coating or stuffing of shellac, rosin, or other-similar resinous cement, applied before the cask is set up, whereby the joints are cemented when the staves are driven up by a cement suitable to resist leakage of beer, molasses, or other watery iluids.

But more particularly to describe my said invention I will refer to the drawings, of which- Figure lis a top view of the eask. Fig. 2 is a cross-section. Fig. 3 is a vertical section through the heads and stavcs, and Fin'. 4 is a section of a stave.

The staves n are each made with two or more tongues, b b, and two or more corresponding grooves, o, as shown in the drawings. The heads d are also jointed with two 0r more tongues, c o, and two or more correspond-ing grooves, ff, if desired. Dowelpins g may be used in putting the head-pieces together.

The staves may be made in the ordinary way, and'tongued and'grooved with a suitable tongue-and-grooving plane, or by machinery which I have devised, and which I intend to describe and show in another application for Letters Pat-ent for the same; but the casks may be made sufficiently well by steaming the staves and bending them by rollers and plain-jointin g by machinery prior to tongning and grooving them, as practiced in large coopera-ges.

I prefer to make the grooves of a V form or a rounded V form 5 but I do not intend to contine myself to the V form of tongues and grooves. Although casks joint-ed as above described are tighter than with plain joints or with single tongued-and-grooved joints, I preferto cement thesedoubletongued-and-grooved joints with a suitable cement applied to the joints before the cask is set up, so that the driving up of the hoops squeezes the cement into the pores of the joints, thus resisting leakage and imparting great strength to the cask.

When the casks are to be used for holding and transport-in g petroleums, alcohol, or similar fluids that do not dissolve glue or similar gelatinous cement-s, I apply to the joints a solution of hot glue by dipping or with a brush, and set them up as quickly a-s possible.

When the staves are properly made and jointed, there is very little difficulty in trussing the casks before the glue sets, especially when the staves have been bent by machinery.

WVhen the casks, barrels, or kegs are to be used to hold and transport boer, molasses, or other watery fluids, I `cement the double tongued-and-grooved joints together with s hellao or rosin, or other similar resinous cements. In making the shellac solution, I prefer to mix together in about equal proportions alcohol, ninety-ve per cent., and coal tar, naphtha, or benzole of about '320 Baums hydrometer; and to one pint of this mixture I put in a pound or a pound and ahalf of FFICE.

common gum -shellac. rlhis makes a good thickvarnish, and does not dry so rapidly as shellao dissolved in alcohol alone, thus giving more time to set up the cask after the cement is applied to the joints. Shellac will, however, answer, if dissolved in alcohol alone or in causticammonia. Rosin cementmay be made by dissolving in a pint of common naphtha one and a half pound of the rosin of commerce; or gumdammar will answer as well.

The casks made as above described maybe coated inside by a coating of glue or shellac, according to the liquid the cask is designed for. The coating ot' the inside is well known, and not necessary to be described, except to say that it may readily be done with glue by pouring into the cask a few gallons of -hot glue solution, and then, by putting in the bung tight and rolling the cask about, the air within, being heated by the hot glue, forces it into the pores of the interior surfaces ofthe heads and staves.

I claim as of my invention and improvement in casks, barrels, and kegs used for holdingwand transporting liquidsi1. The improved Cask, substantially as described,'having its joints made with two or more tongues and two or more corresponding grooves at each joint, substantially in the way and forthe purposes hereinbefore described.

2. In combination with the joints, a cask having its joints made with two or more tongues and two or more corresponding grooves to each joint, and a ooatin g or stufling of glue or similar gelatinous cement applied to the said joints, substantially as and for the purposes described.

3. In combination with the joints of a cask having its joints made with two or more tongues and two or more corresponding grooves to each joint, a coating or stuffing of shellac, rosin, or similar resinous cements applied to the said joints, substantially as and for the purposes described.

JOSHUA MERRILL.
