IMPROVEMENT lN MACHINES FOR DRESSING YARN.

Speciiication forming part of Letters Patent No. 33,222, dated September 3, 1861.

To @ZZ whom it may concern.:

Be it known that I, HUGH WHITEHILL, of Newburg, in the county of Orange and State of New York, have invented certain new and useful Improvements in Machinery for Dressing Yarn; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l represents a plan or top View of my invention. cal section of the same. dinal section of theslotted dressing-cylinder.

Similar letters of reference indicate corresponding parts in the three figures.

This invention consists, first, in the employment of a reed of peculiar construction, being made of a solid longitudinal center bar which keeps the two sections of the yarn separate, and being provided with spring-bars on top and bottom to prevent the yarn jumping over the upright rods of the reed; second, in a mode of regulating the speed of the dressing-brush by the speed of the yarn itself, so that the disadvantages generally arising from a varying speed of the yarn in regard to the brush are avoided; third, in the employment of afluted steam-cylinder for the purpose of avoiding the baking or overheating of the yarn if the dressing-frame is stopped.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

The yarn as it is delivered to the dressingframe from the rollers A B passes through a reed O, provided with a longitudinal central rod ct, which separates the two sections of the yarn. Each section of the reed is protected by a spring-bar b, which rests on the partition-rods c of the reed, and which prevents the yarn from one partition passing over to the other. l If one of the strands breaks While the frame is running, it can easily be lifted over the partition-rod by pushing the spring-bar up for the upper and down for the lower section of the reed, and said springbars always resume their original position by the force of the springs acting upon them. In leaving the reed the yarn goes over the roller D, around the size-rollers E F, and over the dressing-brush G to theroller H, the several Fig. 2 is a longitudinal verti- Fig. 3 is a longitu strands being kept apart by means of a reed C', similar in its construction to the reed C, but without the spring-bars. rl`he brush Gis made out of several sections attached to arms d, as clearly shown in Fig. 2 of the drawings, and as the brush rotates one of its sections after the other is brought in contact with the yarn passing along over the same. Bythese means the yarn has time to recover between the successive actions of the several sections of the brush, and it (the yarn) is therefore less liable to break and become deranged than when eX- posed to the continuous action of the usual brush-cylinder. In passing over the roller H the yarn imparts to the same a rotary motion, and a pulley c, which is secured to the axle of said roller, serves to transmit its motion to the brush G by means of a belt f, which extends from the pulley c over a pulley g on the axle of the brush. By this arrangement the speed of the brush is regulated entirely by the speed of the yarn, so that a uniform action of the brush on every portion of the yarn is effected. From the roller I-l the yarn is conducted to the slotted dressing-cylinder I, which rotates on stationary flanged disks J, and which is furnished with a steam-coil K. This coil passes through the disks J to the interior of the cylinder, and it occupies the space near to its inner surface, as clearly shown in Fig. 3 of the drawings. In the center of the cylinder and attached to the shaft L is the fan-blower M, to which an independent and quick rotary motion is imparted by means of a pulley N on one end of the shaft L. By this arrangement a blast of hot air is thrown against the yarn stretched on the out` side of the cylinder I. From the cylinder I the yarn passes over a roller I to the cylinder O, which is heated by steam in the usual manner; but instead of making the surface of this cylinder smooth I employ a tluted cylinder, so that the currents of cold air are allowed to pass between the yarn and the heated surface of the cylinder, thereby preventing a baking of the yarn if the dressing-frame is stopped.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The arrangement of the reed C, consisting of alongitudinal central rod ct and vertical partition-rods c, in combination with sprng- 3. The employment of a steam-cylinder O bars b, substantially as and for the purpose with a fluted surface, as and for the purpose described. set forth.
