To all whomit may concern:

Be it known that I, GEORGE I. WASHBURN, of the city and county of Worcester, in the v State of Massachusetts, have invented a new and Improved Machine for Straightening Wire; and I dohercby declare the following to be a full and exact description of the same, reference bcin g had to the accompanying drawings,

making part of this specification, in which- Figure 1 is a plan of my improved machine. Fig. ,2 IS a side elevation of the same; Fig.3

This invention relates to a certaiu'novel arrangement of devices whereby wire may be much more readily andeffectually straightened than by machines hitherto employed for this purpose.

The chief or essential feature of my inven-,

tion consists in causing the wire itself to revolve while being drawn between fixed points or rollers, the instrumentality heretofore resorted to to effect the object in view being a a defective arrangement of rotating rollers through which the 'wire is drawn by pinchers.

In order that others skilled in the art to whichmy invention appertains may be enabled to fully understand and use the same, I will proceed to describe its construction and operation.

In the accompanying drawings, A may represent a table or bed, which supports upright standards B B. p v p 0 represents a reel secure] y pivoted within a yoke, D, and adapted to rotate therein and be revolved simultaneous] y therewith, for the purpose to be explained. The yoke D is journaled in suitable boxes in the upper ends of the standards B B, and is designed to be revolved at a veryhigh velocity by steam orother power transmitted from the pulley H on the The rod F passes through apertures in the standards B ll, which constitute bcarin gs therefor, and has an additional bearing in a bracket or car, J, which is rigidly secured to a frame, K.

M M M represent a series of pulleys sccurcd upon the ends of short shafts m m m; and L L L L represent another series of pulleys or wheels secured upon the opposite ends of'thc shafts m, all of said pulleys being adapted to rotate with the shafts m, the latter'passiug transversely through the frame K. The pulleys M may be rotated so as to impart a like motion to the pulleys L by a band, N, from a pulley, O, secured upon the shaft 1*.

drepresents an aperture in the yoke, through .which the wire is drawn from the reel 0 to the wheels L L L L P represents a ball or weight employed to counterbalance the-yoke D while the apparatus is in operation.

The following is the operation of my improved apparatus. The bent wire is first coiled around the reel 0 in customarymanner. One end is then passed through the aperture cl and disposed over the wheel L, under the wheel L, and between the wheels L L as indicated in red lines in Fig. 2. Power being then applied as described, the yoke D, together with the reel (J, is revolved in a vertical plane and the wheels L L L L rotated through the respective bands G N,and these wheels,between which the wire, in passing, is straightened, are designed to constitute feed-rollers, so that the employment of pinchers for drawing the wire between the straightening-points may be dispensed with. Pinchers may,however, if desired, be employed for drawing the wire through the straighteningpoints. By this arrangement it will be seen that the revolution of the yoke D causes the wire to revolve'upou its It is designed toattach to or employ, in

connection with the above 'described apparatus, an automatic device for cutting the wire into lengths as it comes from .the machine.

Having thus described my invention, the

following is whatI claim as new and desire to secure by Letters Patent: i.

l. Causing the wire to rotate upon its own axis as it passes bctwccn'tho straighteningpoints in any manner, substantially as set forth.

2. As an improvement in machines for straightening wire, the combination of the reel 0, yoke D, and wheels L L L L, arranged and operating substantially as and for the purposes set forth.
