MECHANISM FOR PREVENTING A MOLDED BARREL-BODY FROM SHRINKING.

SPECIFICATION forming part of Letters Patent No. 339,064, dated March 30, 1886.

Application filed September 19, 1885. Serial No. 177,567. (No model.)

To all whom, it may concern.-

Be it known that I, GEORGE WAsHING'rON LARAWAY, of Boston, in the county of Suffolk,

of the Commonwealth of Massachusetts, haveinvented a new and useful improvement in mechanism for preventing a molded barrelbody from shrinking in diameter in the mouth of either end of it while such barrel-body is being dried; and I do hereby declare the same to to be described in the following specification,

and represented in the accompanying drawings, ot'which- Figure 1 is a top view, Fig. 2 an edge elevation, and Fig. 3 a transverse section, of a barrel-body supporter of my invention, the nature of which is defined in the claim hereinafter presented.

Barretbodies molded from paperpulp are now extensively made and used. In dryinga body of such kind afterits formation in a molding-machine it is important that each month or part that receives the barrcthead should retain its proper size and shape to fit such head, and this is the purpose of my invention or barrel-body-end supporter, which, on the barrel-body being taken in a moist state from the molding-machine, isinserted init (the said body) at its end and kept there until the body may have become dry. The said body in becoming desiccated shrinks in size; but by having in the mouth or opening at each end of it one of the said supporters while the drying operation is taking place the mouth is preserved in its proper condition and size to re ceive a barrel-head. 5

In the drawings, A denotes a hoop or cylindrical ring. of metal or other proper material,

having a flange, a, extending inwardly from it at top to strengthen it. Across the flange and fastened down upon it is a cross, B, each of whose arms extends a short distance beyond the outer periphery of the ring A. This cross answers not only to further strengthen the ring, but to support it in the open end of a barrel-body by the parts of it that extend beyond the ring resting on the end of the body.

It is important that a ring he used. or, what would be an equivalent, a perforated disk, in order that air may circulate freely through the device to effect the drying of the internal surface of the body.

I claim- As a new article of manufacture, for the purpose described, the pulp barrel end supporter substantially as represented, consisting of the cross and the flanged ring, substantially as set forth.

GEORGE WASHINGTON LARAWAY.
