EDWARD W. ROBINSON, OF SAVANNAH, GEORGIA, ASSIGNOR, BY MESNE ASSIGN- MENTS, TO INTERNATIONAL BARREL COMPANY, OF SAVANNAH, GEORGIA, A
CORPORATION OF GEORGIA.
To all whom it may concern Be it known that I, EDWARD W. ROBIN- SON, a citizen of the United States, residing in Savannah, Georgia, have invented certain Improvements in Barrels, of which the following -is a specification.
My invention relates to barrels composed of staves interwoven with properly spaced pairs of wires which take the place of the usual hoops for retaining the staves 1n proper relation to one another, and my nvention relates particularly to a barrel of this type intended mainly for the storage and transportation of powdered and granular material and technically known as a slack barrel in contradistinction to one which is technically known as a tight barrel and which is intended for the storage and transportation of liquids.
One object of my present invention is to so construct the barrel as to prevent leakage of the powdered or granular material therefrom, and another object is to provide for the firm and rigid support of expansion heads in the opposite ends of the barrel. These objects I attain in the manner herelnafter set forth, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation of a barrel constructed in accordance with my present invention; Fig. 2 is an edge view of part of one of the staves to be used in the manufacture of the barrel; Fig. 3 is a sectional view showing said stave after it has been interwoven with a pair of wires and the latter have been twisted between adjoining staves; Fig. 4 is a horizontal sectional view of the edge portion of the stave; Fig. 5 is a horizontal section showing two adjoining staves interwoven with a pair of wires which have been twisted together between the staves; Fig. 6 is a similar view illustrating another embodiment of my invention, and Fig. 7 is a vertical sectional view of part of one end of the barrel, and part of the expansion head employed in connection therewith.
The barrel is composed of staves 1 which are preferably narrower at the ends than at the center so that when the staves are drawn together until their edges meet, the barrel will present the desired bulged form, the edges of the staves being preferably beveled slightly in order to insure their close fitting to one another. The staves are confined in position by as many pairs of wires 2, 2 as Specification of Letters Patent.

it may be desired to employ, the stave being inserted between the wires of each pair and the latter being twisted together, as at 3, between the staves, which are thus firmly held in the desired relation to one another.
In order that the staves may fit closely one to another provision must be made in the staves for the reception of the twisted portions of the wires and such provision constitutes one of the features of my invention. In one edge of each stave I form a closed mortise 4:, closed in this connection meaning that the mortise does not extend completely through the stave from the inside to the outside of the same but has walls 5 on each side of the mortise, or, at least, a wall 5 on the inner side of the same. When, therefore, a stave is inserted in the 'open shed of wires and said shed is closed and the wires twisted together, the wires will bear firmly on the inner andouter sides of the stave and, owing to the tension upon them, will cut through the center portions 'of the walls 5' so that the twisted portions 3 of the wires will occupy the mortise 4, the size of the mortise being so proportioned in respect to the size of the twisted wires that thelatter will practically fill the mortise, the walls of the latter partially inclosing the twisted wires, so that the only channel of communication between the inside of the barrel and the mortise in that provided by the displacement of the center portion of the inner wall by the inner wire 2*, and the only channel of communication between the mortise and the outside of the barrel is that caused by thedisplaoement of the center portion of the outer wall by the outer wire 2 and these displaced portions of the wood being jammed between the twisted portions of the wires so as to close any channel of leakage through the latter which might otherwise exist. When the mortise l is formed entirely in one edge of the stave the wires 2, 2 engage the unmortised edge of the adjoining stave as shown in Fig. 5, the body of the stave at the base of the mortise and at the corners of the unmortised edge of the stave being indented by the wires,
owing to the tension under which said wires are twisted.
Instead of providing at one edge of each stave a mortise deep enough to receive the entire extent of the twisted wires, I may provide a shallower mortise in each edge of the stave, as shown for instance in Fig. 6,
the mortises of adjoining staves in that case serving to contain the twisted portions of the wires.
In connection with my improved barrel I employ an expansion head of any suitable type, the outer members of this expansion head having peripheral grooves for engaging the inner wire 2 of the pair at the end of the barrel, and in order that this wire may provide a firm and rigid support for the head of the barrel I differentiate the wires of each end pair, the inner wire be ing considerably heavier than the outer one, as shown in Fig. 7, and I, preferably, so twist the wires between the adjoining staves that the heavy wire 2 will always lie 011 the inside of the staves.
1. A barrel consisting of closely fitting staves having edges with closed mortises,
said staves being interwoven with pairs of wires which are twisted between the staves, the twisted portions of the wires being located in said mortises, and the wires passing through the side walls of the latter.
2. A barrel consisting of closely fitting staves each having one edge plain and the opposite edge provided with closed mortises, said staves being interwoven with pairs of wires which are twisted between the staves, the twisted portions of the wires being located in the niortises and the wires passing through the side walls of the latter.
In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
