T0 ALL-WHOM IT MAY corvonnrv:

Be it known that we, DEWEY PHILLIPS, of Shaftsbury, in the county of Bennington, and State of Vermont, and WILLIAM REID, of West Arlington, in the county of Bennington, and State of Vermont, have invented-a new and useful Method of Securing the Heads in Seamless Kegs or Casks, or bottoms in tubs, bn'ckotaand other like articles; and we'do hereby declare that the following is a full, clear, and exact description thereof, reference being bad to the accompanying drawings making part ..of this-specification, in which-.

Figure 1 is an elevation of a cask completed according to our improved method; and

Figure 2, a section thereofrtaken in the plane of the axis of the cask.

Oursaid invention relates to a methodof securing the heads in seamless kegs and c asks, or the bottoms in tubs, pails, and other like articles that are made by cutting cylindrical shells from .tolid blocks of wood.

Prior to our said invention the heads or. bottoms were put into such seamless articles by making the heads or bottoms of a diameter a little greater than the inner diameter of the shell where the crozewas -formed,and then steaming the end of the shell to admit of stretching or expanding jitsuificiently to permit the head or bottom to be inserted, relying upon the shrinkage of the wood afterwards to close around. and hold it. This method, however, was found to be so defective that it could not be successfully introduced into practice. The

w-ood-,--after having been-so steamed-and expanded, was very liable to leak, and the head or bottom to drop out,

if exposed-to the drying influence of the atmos'phere without a liquid inside. According to our improved method we make the heads, a a, or the bottom, of less diameter than the inner diameter of the shell 1 at' the craze, so that'they can be'readily introduced without stretching or expanding the shell, and, whilst theheads (or bottoms) are held in place by the application of pressure to the outside of the shell at or near the ends and all around, we compress the wood until the croze is brought into close contact with'the edges of the heads, and .beforethewood which has'been so compressed can expand, we drive on the hoops c c, .to hold the wood in the compressed condition. The compression of the shell on to the heads or bottoms may be effected by'means of a conicalmetal hoop driven on to the vessehor by means of an expandingand contracting hoop, made to expand or contract by means of a screw-bolt orvwedge, or by any other known means of concentric pressure; :do not, however, claim any method or machine for effecting said compression, but we prefer to effect it by means of machinery invented by WILLIAM REID, one of these applicants,.subsequently to our invention herein described, for which the said REID filed an application forl etters Patent the 12th day of March, 1866. After having been so compressed and held for a time, the wood has no disposition to expand and leave the heads (or bottom) even when the hoops are taken off. And the compression of the wood closes the pores so completely as toprewent all leakage. By this method all kinds of'coopers work can be produced at. less cost and of a better quality than when made of staves. V We do not claim broadly, as of our invention, the insertion of heads or bottoms in the shells of seamless casks and other vessels, but what We do claim as our invention, and desire to secure by Letters Patent, is-- The method herein described of putting the heads or bottoms in seamless casks or other vessels, by making the heads or bottoms of a less diameterthan the inner diameter of the shells at the croze, and then compressing the ends of the shell into close contact therewith,- preparatory to putting on the hoops, substantially as described.
