HVHTATION TWlSTElD WIRE.

SPECIFICATION forming part of Letters Patent No. 299,285, dated May 2'7, 1884.

Application filed December 17, 1883. (N model.)

To all whom it may concern.-

Be it known that I, J AMES SPRUCE, of Waterbury, in the county of New Haven and State of Connecticut, have invented a now Improvement in Imitation Twisted IVire; and I do hereby declare the following,when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

Fignre 1, a perspective view of the wire as drawn; Fig. 2, aperspective view of the wire as twisted-both figures enlarged for conven- 1 ience of illustration.

This invention relates to an improvement in the article commonly known as twisted wire, and such as used for the manufacture of various articles, useful and ornamental, as

for table-service, card-receivers, frames, bas

kets, and the like. The material for themanufacture of these articles has hitherto been made by twisting together several small round wires. Great care is necessary in the use of 2 5 these twisted wires in the manufacture of such articles, from the fact that in making short bends the convolutions of the wire are liable to separate, and to reduce theliability of such separation the wires are required to be very o closely twisted because it would be impractical to bend long twists so short as in many cases is necessary.

The object of my invention is to produce an article which shall have the appearance of several small round wires twisted together but in one solid piece, whereby not only is the article having the same appearance as the twisted wires produced much more cheaply than the twisted wire can be, but better, in that it is 0 impossible to separate the convolutions, and

the twist may be shortor long, according to the requirements of the trade.

The invention consists in a wire drawn solid to represent two or more round wires twisted 5 to give to it the appearance of several round wires twisted together, and as more fully hereinafter described.

In illustrating my invention I show a wire composed of three ribs that is, to represent threesmall round wires twisted together. In

transverse section the drawn wire a is trefoil shape, as seen in Fig. 1. This wire is drawn through dies of corresponding shape in the usual manner of drawing wire. Then this ribbed wire is twisted, as seen in Fig. 2, and when so twisted has the appearance of several round wires twisted together, and such as commonly used in the manufacture of articles, as before mentioned. a

As but asingle wire is required to be drawn, instead of three to produce the same result, the cost of drawing is therefore very much re duced. Again, the cost of twisting the single wire is much less than that of twisting severalwires together.

Because of being a solid wire, instead of several wires, the length of twist may be long or short, as occasion requires, for by no possibility can the several convolutions be separated, no matter whether the bend be long or short. The article is therefore not only cheaper but better than the several wires twisted together which have the same appearance as the solid article.

The description as applied to trefoil wire will be sufficient to enable those skilled in the art to adapt the invention to represent a greater or less number of round wires twisted together, it only being essential to my invention that the wire shall have substantially the ap- 8o pearance of separate strands or convolutions of drawn round wire.

I am aware that an angular wire or rod has been twisted to give to its surface a spiral appearance; but I am not aware that a wire has been made in imitation of several round wires twisted together.

I claim- As an article of manufacture, the herein-described wire inimitation of twisted wires, con- 0 sisting in a single or solid wire the surface of which represents two or more round wires laid together, the said wire twisted to give to it the appearance of several round wires twisted together, substantially as described.

JAMES SPRUCE.
