75g: 4 HUGH MILL EA BY E Patented Nov. 14, 1950 2,529,563 STRETCH TUBE onmcn Hugh Miller, Meadville, Pa., assignor to American Viscose Corporation, WilmingtomDeL, a corporation of Delaware Application December 24, 940, Serial No. 718,182
' Claims. (Cl. (st-212)- This invention .relatesto apparatus for the treatment of'filaments, yarns, threads and the like, and relates more particularly to an improved orifice'device. adapted tobe used as an entrance or exit for yarns or the like to fluid treatment chambers, such as stretch tube assemblies.
In the prior art there has been used as an outlet orifice a cock or plug valve with a transverse slot cut in it to permit wide opening for lacing and allow the thread to continue through the orifice when it is partially closed. These cocks or plug valves also had stopson them, so that when they were new they all theoretically had the same size opening. However, this ideal result could never be achieved due to difilculties imposed in machining an elliptical groove in a tapered surface on' the side of the-cock and also the location of a stop accurate enough to permit the opening always to occur at the same point. These cocks wore rapidly because of the impracticability of making them of materials which are sufiiciently resistant to the rubbing action of the yarn, especially in the presence of treating fluids such as steam, having erosive and/or corrosive action upon the cocks. This wear changed the orifice area and thereby caused an increase in the escape of treating fluid from the chamber and rendered it difflcult to maintain constant, treating conditions in the chamber.
The disadvantage of the prior art is overcome in the present invention which provides two relatively rotatable oriflced discs which can be made practically of a hard wear-resistant material such as sapphire, ruby, or other gem stones, or Alsimag, lava, glass, porcelain, etc.
The main object of the present invention is to provide a complementary mating means between two orificed discs for maintaining constant registry between a predetermined area of each orifice at all times.
Another object of the present invention is to avoid the practical difliculties inherent in the machining of a cook or other flow-regulating device to be used as an orifice for the passage of filamentary material.
Other objects and advantages will become apparent from a study of the description of the following drawings.
In the drawings,
Figure 1 is a side view of the present invention in section,
Figure 2 is a top view of the lower of the two discs employed,
Figure 3 is a sectional view of Figure 2 taken along the section lines A-A of Figure 2,
Figure 4 is a bottom view of the upper of the two discs employed, and,
Figure 5 is a sectional view of Figure 4 taken I I along section lines B-B of Figure 4.
As shown in Figures 1 to 5 and more particularly in Figure 1, reference character 2 indicates a supporting member suitably mounted and surrounding the lower end of the treating chamber' or tube I. The supporting member 2 is bored out just below the treating tube I to accommodate two relativelyrotatable elements which may take the form of discs. As specifically shown herein,
. reference character 3 indicates a stationary disc pressed therein and a rotatable disc 4 rotatably mounted therein. Means are provided for rotating disc 4. Thus, pins 5 project from the rotatable flanged body 6 into suitable bores in disc 4. The flanged body 6 has a longitudinal bore therethrough to accommodate the thread, strand, yarn orother filamentary material as it passes through the device.
The handle I attached to the body of the flange facilitates operation outside the treating chamber. The flanged body 6 is held in place on the supporting member 2 by a threaded coupling 8 screwed to the outside of the supporting member 2 and locked in place by a lock'nut 9.
There are complementary mating means between the two discs for holding part of the orifice in registry at all times as shown in Figures 2 and 5. Rotatable disc 4 has a tongue I3 concentric with the circumference of the rotatable orifice. This tongue fits into a similar concentric groove in the stationary disc 3.
The large eccentric, semi-circular portion I5 of the orifice in the rotatable disc 4 is opposed to a portion I4 and is connected therewith by a passage between two opposite lateral walls. The large eccentric, semi-circular portion I2 of the orifice in the stationary disc 3 is opposed to a concentric semicircular portion II and is connected therewith by a passage between two opposite lateral walls. It can be seen that by rotating rotatable disc 4 in such a direction that the large orifices I2 and I5 on discs 3 and 4 respectively are apart, it will form acircular orifice made of orifices I I and I4. By rotating the rotatable disc another 180 it will bring the orifices I2 and I5 into an overlapping position forming a much larger orifice. The larger orifice allows for lacing and the smaller maintains constant treating conditions in the chamber, such as proper steam temperature.
When the large orifices I2 and I5 are in an opposed position so that the small circular orifice is 3 formed, there is a spaced portion between them. due to the passage between the two walls connecting each with its respective smaller orifice.
The spaced portion prevents any leakage oi the trceating fiuids except through the circular ori- The longitudinal bore in the fiange body is of such a diameter that it is larger than the small circular orifice formed and smaller than the area oi the large orifices when they overlap. This prevents any clogging or Jamming oi the filamentary material during the treating or lacing operation.
It is to be understood that changes and variations may be made without departing from the spirit and scope of the invention as defined in the appended claims.
I claim: I

Yarn guiding apparatus comprising supporting means, two relatively rotatable adjacent orificed discs having a common axis mounted on the supporting means, the orifice in each disc having a central area communicating with an eccentric area, means for rotating one of the discs relative to the other, complementary mating means between the opposed faces of the two discs for holding the central area of each orifice in registry in all relative positions of the two discs.
