Definitions

  • This invention relates to the manipulation of multiple yarns or tows and more particularly to the propulsion of and liquid recovery from a running tow of viscose rayon.
  • Another object of this invention is to provide a sheave having suction means for withdrawing liquid from the tow groove which is characterized by a high degree of pump ing economy in the maintenance of the desired suction.
  • Figure 1 is a view in elevation of a tow propulsion Wheel according to the present invention in a typical position of use;
  • Figure 2 is a view in section of the tow wheel of Figure 1 taken on the line 22 of that figure;
  • FIG. 3 is a fragmentary view in section taken on the line 3-3 of Figure 1;
  • Figure 4 is a view in elevation of a modified type of tow propulsion wheel according to the present invention.
  • Figure 5 is a view in section taken on the line 5-5 of Figure 4.
  • Figure 6 is a view in section taken on the line 6-6 of Figure 4.
  • the feed or transfer wheel 10 of the present invention is a sheave or pulley having a peripheral groove 11 of arcuate cross section for tow and a narrow annular groove 12 at the bottom of the tow groove 11.
  • a series of radial passageways 13 extend inwardly from the groove 12 to a common inner annular space or manifold 14 located in the hub of the wheel 10.
  • the wheel 10 is fixed on hollow hub portions 15 and 15a which define between them an annular space registering with the inner manifold 14 of the wheel 10 and placing that manifold in communication with the hollow interior of the hub portions.
  • the hub portion 15a is a part of a hollow stub shaft 16a closed at one end.
  • the hub 15 is a part of hollow shaft 16 the interior of 2 which is served by a vacuum connection 18 which comprises a box sealed against leakage at 19 and 20 to the shaft 16 and providing an interior annulus 21 served by a conduit 22.
  • the shaft 16 is provided with ports at 23 which register with the annulus 21.
  • a suitable vacuum pump not shown, is connected to conduit 22, which together with ports 23, shaft 16 and manifold 14, provides conduit means for permitting application of suction to passageways 13.
  • the load on this pump would be very high indeed for a tow extending for as short an are as is indicated in Figure 1 were it not for the sealing of the groove 12 in the portions of the arc of movement where there is no contact with the tow.
  • a sealing shoe 24 is provided to bear on the bottom of the groove 12 in the portion of the arc of movement where there is no tow.
  • the shoe is provided with a slot through which it may be adjustably bolted to a stationary part of the machine.
  • the guide wheels 25 and 26 may be ordinary pulleys or may be of the type of the present invention.
  • a typical tow path is shown in Figure l and the effect of it, due to the suction created, is to make a good positive drive for the tow at the same time to extract considerable residual treating liquid or other moisture therefrom.
  • Shaft 16-1641 is, of course, provided with ordinary bearings, not shown. It is to be understood that the sheave 10 and the shaft 1616a turn as a unit. The propulsion of the shaft 1616a is accomplished by any convenient means, not shown.
  • the sheave bears reference numeral 27.
  • the sheave is an assembly which is made up of two cast elements or sides 28 and 29 which are mutually complementary.
  • the elements 23 and 29 each include a central space or manifold 30, 31.
  • Grooves or channels 32 and 33 extend radially outwardly from the manifolds 30 and 31. These grooves are cast or cut on the inner faces of the sheave elements 28 and 29 and they extend for less than the full radius of the half sheave.
  • Marginal complementary peripheral grooves define a tow groove 34 having an arcuate cross section.
  • This plate is so shaped that its upper half does not cover the ends of the grooves 32 and 33 while its lower half does, see Figure 4.
  • FIG. 4 Aside from the foregoing differences, the structure of the embodiment of Figures 4, 5 and 6 is not very different from that of Figures 1, 2 and 3.
  • the sheave elements are mounted on a hollow shaft 36 by hub members 37 and 38 so that the shaft 36, the hubs 37 and 38 and the sheave elements 23 and 29 turn as a unit.
  • Shaft 36 has a series of ports 39 leading to manifold 30 and another series of ports 40 leading to manifold 31.
  • Still a third series of ports 41 lead to the annular interior 42 of a suction box 43 provided with a suction conduit at 44.
  • the path of the tow to, from and over'the sheave 27 may be the same as is shown in Figure 1.
  • the shaft 36 and the sheave 27 turn as a unit, but the plate 35 is.
  • a sheave having a tow groove, a suction groove at the bottom of the tow groove and means to seal the suction groove during those parts of the annular movement in which the groove is not in radial registry with tow.
  • conduits 2-2 and 44 may be used to withdraw treating liquidswhich may then be delivered to suitable recovery apparatus.
  • a rotatable wheel for the propulsion of tow said wheel having a marginal groove of arcuate cross section for the reception of the tow, a narrower groove at the bottom of said marginal groove, circumferentially spaced ports extending radially within said wheel and communicating with said narrower groove, means to apply suction to said ports and stationary sealing means occupying said narrower groove in a part of its path of rotation, said sealing means extending beyond the periphery of the wheel.
  • a rotatable wheel for the propulsion of tow said wheel having a marginal groove of arcuate cross section for the reception of the tow, a narrower groove at the bottom of said marginal groove, a hollow shaft supporting said wheel for rotation, means to apply suction to the hollow interior of said shaft, means establishing passageways interconnecting the hollow interior of said shaft with said narrower groove at circumferentially spaced points thereabout and stationary sealing means occupying said narrower groove in a part of its path of rotation, said sealing means extending beyond the periphery of said wheel.
  • a rotatable wheel for the propulsion of tow said wheel having a marginal groove of arcuate cross section for the reception of the tow, a narrower groove at the bottom of said marginal groove, circumferentially spaced ports extending radially within said wheel and communicating with said narrower groove, means to apply suction to said ports, a plate having an arcuate edge complementary to said narrower groove, means located beyond the periphery of said wheel to hold said plate stationary with the arcuate edge in said narrower groove to seal the same in a part of its arc of movement.
  • a rotatable wheel for the propulsion of tow said wheel having complementary sides mounted for rotation about an intermediate stationary spacer plate and defining therebetween a marginal tow receiving groove of arcuate cross section, at least one of said sides having radial grooves therein extending short of said tow groove, said sides being spaced apart so that said grooves communicate with said tow groove, and means to apply suction to the radially inner end of said grooves, said plate being radially shorter than said grooves in one sector thereof and radially longer than said grooves for the remaining sector thereof whereby in said radially longer sector said radial grooves are closed.
  • a rotatable wheel for the propulsion of tow said wheel having-complementary sides mounted for unitary rotation about an intermediate spacer plate and defining therebetween a marginal tow receiving groove of arcuate cross section, each of said sides having radial grooves therein on the side facing said plate, said grooves terminating short of said tow receiving groove, said sides being spaced apart so that said grooves communicate with said tow groove, means to apply suction to the radially inner ends of said grooves, said plate being radially shorter than said grooves in one sector and in the other being radially longer than the grooves, a portion of the radially longer sector extending beyond the margins of the wheel to constitute a support.
