Application filed September 25, 1913. Serial No. 791,856.

To aZZ whom it may concern:

Be it known that I, EDWAR I. BRADDOCK, a citizen of the United States, residing in Viinchester, in the county of Middlesex and State of ltlassachusetts,have invented an Improvement in Wire-Bound Articles, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention relates to a wire-bound article and is herein shown as embodied in'a hollow article bound with wire hoops.

The invention is especially adapted for embodiment in a hollow, non-metallic article, such as a wooden firkin, tub, pail, loarrel, or the like, and has for its object to provide a superior article at a minimum cost. To this end, the article to be bound,

which will be hereinafter referred to as a firkin, is employed as a former upon which is wound a plurality of coils of wire in a heated condition and preferably covered with a coating of solder or like metal of a melting point which is relatively lower than the wire, so that continuous convolutions of the coil of wire may be molecularly united to form a wire hoop, which is afhxed to the firkin by the contraction of the wire hoop when cooled. As the heated wire is wound upon the firkin, it chars or burns grooves in the outer surface of the firkin, which serve to retain the wire hoop upon the tirkin against movement longitudinally of the firkin, and the wire hoop may also be retained on the firkin against movement, by means of spurs formed by bending the wire at the ends of the coil and driving them into the firkin. These and other features of this invention will be pointed out in the claims at the end of this specification.

Figure 1 is an elevation of a firkin embodymg this invention. Fig. 2, a vertical section of the firkin shown in Fig. 1. Fig. 3, a like section of the firkin wlth the wire hoops removed to illustrate the embedding of the wire. Fig. 4, a cross section on the line 44, Fig. 1. Fig. 5, a detail of one of the hoops, and Fig. 6, a detail in vertical section to illustrate the holing spurs, the section being taken on the line 66, Fig. 1.

In the present instance, I have illustrated a preferred form of the invention, which comprises a firkin aof wood or other nonmetallic material and such as now commonly made, which is provided with one or more Wire hoops Z), herein shown as three in number. Each of the hoops b is composed of preferably a plurality of convolutions of iron, steel or other wire, having thereon a coating of solder of like non-corrosive metal or alloy of metals of relatively lower melting point than the wire, and said convolutions are preferably arranged so that the coatings on adjacent convolutions contact for the length of the convolutions and unite and thereby molecularly join the convolutions of the wire coil together to form a hoop.

The first and last turns or convolutions of the wire hoop are provided with bent and preferably pointed ends 0, d (see Fig. 6), which are driven into the firkin' and form spurs or *mechanical holding devices, by which the Wire hoop is secured to the firkin against movement circumferentially and longitudinally. The wire hoop b is also secured on the firkin against longitudinal displacement by means of grooves 6, (see Fig. 3), Which are formed by the wire being wound in a heated condition upon the firkin, and allowed to cool thereon.

As the heated Wire cools, the firkin and grips the same firmly, so that if desired the contraction of the wire alone could be depended upon to secure the wire hoop thereto, especially when the convolutions of the wire are molecularly united as above described. 011 the other hand, the spurs c, d, may be depended upon to secure the hoop on the firkin, in which case an uncoated wire may be used, but it is pre-' ferred to employ both methods of securing the hoop on the firkin.

In the manufacture of the hooped firkins commercially, a suitable machine will be provided in which the firkin is secured so as to be rotated, and the wire will be led through a bath of molten solder contained ina heated vessel, and either the said vessel or the firkin will be'given a longitudinal motion, one with relation to the other, to cause the wire to be properly fed longitudinally on the firkin so as to lay the convolutions in contact with one another. Provision will it contracts upon also be made for forming a spur at the beginning of the wire, which is driven into the iirkin, and for cutting the coiled wire from the straight portion, bending it to form a spur and driving this into the firkin.

The machine is not herein shown as it forms no part of the present invention and is not necessary for a proper understanding of the same.

It will thus be seen that automatically coopered.

It will further be observed that a strong firkin is obtained, inasmuch as it is bound by wire hoops, which are retained on the firkin by the contraction of the wire and by the spurs or holding devices, which are integral with the hoops. Furthermore, the wire hoops are materially strengthened by the union of the coating of solder on contiguous convolutions.

B the term iirlrin as used in the claims, I desire to be understood as including not only the article commonly called a firkin, but also pails, tubs, barrels and like non metallic hollow articles. I

The staves comprising the firkin are temporarily held together by a metal band or ring, which is removed after the wire hoops have been wound thereon.

lin coopering the firkin, the hoops may be formed simultaneous y or individually.

Claims 1. A firlrin comprising a hollow non-metallic member having thereon a wire hoop composed of a plurality of convolutions soldered together and embedded in the outer surface of said member with the convoluthe firkin may be tions of the wire set and substantially relieved from tension.

A firki'n comprising a hollow non-metallic member having thereon a wire hoop composed of a plurality of convolutions soldered together and embedded in the outer surface of said member with the convolutions of the wire set and substantially relieved from tension, said hoop having bent portions which are embedded in the said member.

A firkin comprising a hollow, non-metallic member having thereon a wire hoop composed of a plurality of convolutions secured on the said member by the contraction of the wire into a set condition substantially free from tension, substantially as described.

4:. A fir-kin comprising a hollow, non-metallic member having thereon a wire hoop secured thereon by the contraction of the wire into a set condition substantially free from tension and provided with bent ends which are embedded in said member.

5. An article comprising a hollow member having thereon a wire hoop composed of a plurality of convolutions soldered together ant secured on the said member by the contraction of the wire into av set condition substantially free from strain, substantially as described.

In testimony whereof, I have signed my name to this specification in the presence oi two subscribing witnesses.
