16 Claims. (Cl. 8-151.1)

Another object of the invention is to provide improvements in apparatus for subjecting traveling yarn, thread, and the like to successive liquid treatments without substantially mixing the liquids during the operation.

A further object of the invention is to provide improvements in apparatus for subjecting traveling yarn, thread, and the like successively to treatments with diflerent liquids.

These and other objects of the invention will be apparent from the following description and accompanyin drawing.

In the drawing, v

Figure 1 is a vertical sectional view of a preferred embodiment of the invention taken on the line 1-1 in Figure 2.

Figure 2 is an end elevational view of the embodiment of the invention shown in Figure 1.

Referring to the drawing, reference character 2 reference character I.

is supported on the reservoir, in contact with the upper extremity of the inner wall of the drum, with portion ll of the wiping blade in contact with the upper extremity of the inner wall of the annuiar chamber. The lower portion of the wiping blade comprises a plurality of depending members it. The sides of the depending members, which are adjacent the inlet end 01' the drum. extend at an angle downwardly and toward the discharge end of the drum. The upper extremity of the wiping blade has projecting portions l 9 which engage the portions of the inner wall of the drum between the ridge members. A liquid receiving tank In is positioned beneaththe discharge end of the drum.

Various means may be used for passing the.

yarn, thread, or the like 34 through the drum. The means shown in the drawing comprises the thread advancing reel generally indicated by The reel is composed of a plurality of pairs of pulley members 26 and 21 which are pivotally mounted to rotate in the same plane between the pairs of outwardly extending arms 23 and 24 on the spiders 2| and 22 which are 25 fixed to the rotatable shaft 25. Continuous belt indicates generally means for applying liquids to traveling yarns, threads, and the like. The liquid applying means comprises a cylindrical drum 9 mounted to rotate about its axis which is substantially horizontal on the rollers I mounted on the drive shaft 6, and the rollers l9 mounted on the shaft 29. The drum is rotated about its axis by the gear 8 fixed to the drive shaft 8 which is in mesh with the gear 5 mounted on the periphery of the drum. An annular liquid receiving chamber.

comprising a cylindrical portion 4 and inwardly extending annular flanges l1 and I8 isattached to the liquid receiving end of the drum by the flange H. The radial dim'ension of the flange I9- is less than that of the flange l1 and the inner diameter of the flange I8 is greater than the outer diameter of the drum. A reservoir 9 forthe liquid to be applied to the yarn, thread, or the like is positioned at the receiving end of the drum into which a portion of the annular liquid receiving chamber extends. Liquid is maintained in the reservoir at alevel above a portion of the inner extremity of the flange l8 so that liquid will flow from the reservoir into the annular chamber.

The inside of the drum is provided with a plurality of parallel ridges l5 which extend all the way around the inside of the drum and at right angles to the axis of the drum. A wiping blade member I I is mounted on the standard l2, which members 33 for supporting the yarn, or the like pass over each pair of pulleys. Worm wheels 28 a are iixed to the pulleys 21 and rotate about the same centers and in engagement with the worm gear 29 flxed to the sleeve 39. The sleeve is mounted in a suitable bearing and is rotated relative to the reel supporting shaft 25 by the gear 3| fixed to the sleeve and driven by suitable driving means which are not shown. The reel shaft 25 is rotated by-the gear 32 flxed to the shaft and in mesh with a suitable driving gear which is not shown. The shape of the teeth on the worm wheels 28 and on the worm gear 29 are such and the relative rotation of the spider and the worm gear are such that the outer pass of the belt members 33 moves towards the liquid inlet end of the drum as shown by the arrows in Figure 1.

In the operation of the invention, yarn, thread. or the like 94, to be subjected to liquid'treatment is directed onto the reel member adjacent the liquid discharge end of the drum and the helix of yarn or thread that is formed on the reel is advanced towards the liquid inlet end of the drum. Liquidfrom the reservoir flows into the annular chamber which is rotating with the drum and the liquid that adheres to the walls of the chamber is carried upwardly to the wiping blade.

The portion ll of the wiping blade removes the inclined side of the depending portion of the wiping blade and drips oil the point of the depending portion into the drum. The rid e members in the drum confine the liquid that drips off the depending portions of the wiper blade to a relatively narrow region below the portion of the wiper blade 03 of which the liquid drips. By means of the inclined sides of the depending portions oi. the wiping blade, the liquid progresses through the drum in successive steps from the inlet end to the discharge end. As liquid is maintained in the annular chamber the liquid will drip from the depending portions of the wiper blade in substantially steady streams. The annular chamber in eiTect serves as a metering device and the liquid is introduced into the drum at a uniform rate. The liquid will flow out of the drum at the discharge end 'after being applied to the yarn a. plurality of times as the yarn moves on the reel through the drum. The yarn is moved through the drum in a direction counter to the direction in which the liquid flows through the drum. Where yarn containing chemicals such as acid, sulphur, and the like which will contaminate the treating liquid is processed, the yarn will be first treated with liquid that is contaminated and then with purer liquid as the yarn approaches the inlet end of the drum until it is treated with pure liquid at the inlet end of the drum. The ridges in the drum prevent the liquid from mixing to any great extent in the drum.

This invention may be used with a single drum, but where it is desired to treat the yarn with different kinds of liquids, a plurality of axially spaced drums, one for each treatingliquid, may be used. In Figure 1 of the drawings is shown such an arrangement with two liquid treating drums in which the drum 40 and associated parts are the same as in the drum 2. i

In order to treat a plurality of yarns a plurality of drums may be arranged in side by side relation with the annular chambers on the drums extending into the same reservoir, which is of sufllcient length to supply liquid to all the drums.

While preferred embodiments of the invention have been disclosed, it is to be understood that changes and variations may be made without departing from the spirit and scope of the invenhollow member mounted to rotate about a sub--.
