is claims. (ci. s7-sa49) The present invention relates to spindles and, more specifically, to two-for-one twisting spindles or double twisting spindles. In connection with this type of spindles, it is known to subject the thread or yarn to a moistening treatment by contacting the thread or yarn directly with a liquid or a vaporous medium. In addition thereto, it is known to treat the thread or yarn with a finishing or brightening agent over which the thread passes and from which the thread or yarn absorbs the substance. These heretofore known treatments are intended to improve the sliding property of the thread or yarn during the processing thereof and to hold said thread or yarn smooth and flexible to thereby prevent thread breakage and the formation of dust.
It is an object of the present invention to provide a two-for-one spindle which will make it possible to treat the thread withdrawn from a bobbin with a wetting agent or with a finishing or brightening agent at a particularly suitable section.
It is another object of this invention to provide a twofor-one spindle, which will permit subjecting the thread or yarn to a moistening treatment prior to the starting of the twisting operation and specifically, where the thread is reversed in its direction of movement.
These and other objects and advantages of the invention will appear more clearly from the following specification in connection with the accompanying drawings, in which:
FIGURE 1 diagrammatically illustrates partly in section a two-for-one spindle with a cylindrical body composed of a hard moistening or brightening agent (Hartavivage);
FIGURE 2 illustrates partly in section a two-forone spindle with a cylindrical body forming an annular cup adapted to receive and store a wetting agent;
FIGURE 3 shows partly in View and partly in section the upper end of a hollow spindle shank with a paraboloid of rotation placed on the upper end of a hollow spindle shank and adapted to release a wetting agent, a finishing or brightening agent, or the like;
FIGURE 4 illustrates partly in view and partly in section a paraboloid of rotation similar to that of FIGURE 3 but somewhat modified thereover inasmuch as the spindle shank is, in contrast to that of FIGURE 3, not straight;
FIGURE 5 represents a further embodiment of the present invention equipped with a relling means;
FIGURE 6 shows the arrangement of a material adapted to exert a suction and located on the dish-shaped disc of the paraboloid of rotation according to FIGURE 5.
A two-for-one spindle according to the present invention is characterized primarily in that a cylindrical body or the like adapted to release a wetting agent, a nishing or brightening agent or the like, is mounted on that end of the hollow spindle shank which is located above the bobbin. The upper end face of said cylindrical body is shaped in conformity with the body of rotation which is described by the thread which, while being withdrawn from the bobbin, enters the hollow spindle shank. When the thread or yarn is wound olf from the bobbin in upward direction and is then deviated downwardly into the hollow spindle shank, the thread or yarn automati- Patented Jan. 3, i967 cally at a certain pressure at the deviating point contacts the end face of the wetting agent or finishing or brightening agent whereby the thread or yarn absorbs a certain quantity of the said wetting or finishing agent, with the result that an electrostatic charge of the thread or agent and the parts contacted thereby will be avoided while the thread or yarn itself is made more flexible.
In conformity with the invention, the cylindrical body placed upon the hollow spindle shank may consist of a hard finishing or brightening agent. Such cylindrical body may when used up, be replaced by a new similar body. For purposes of protecting the cylindrical body consisting of a hard nishing or brightening substance, and for purposes of guiding the thread or yarn over the upper end face of the cylindrical body, the latter may be surrounded by a bushing extending up to the upper end face, said bushing being connected to the hollow spindle shank.
According to a further development of the present invention, the cylindrical body may be in the shape of an annular cup adapted to be filled with a liquid wetting agent or the like while being provided at its upper end with an absorbent closure member and wick means extending into the interior of said cup and the wetting agent stored therein. The upper end face of said closure member is adapted to the shape of a body of rotation described by the thread or yarn withdrawn from the bobbin and deviated into the hollow spindle shank.
According to a further development of the invention, the said cylindrical body releasing the wetting agent or finishing or brightening agent may additionally release wetting substance to the thread or yarn passing substantially vertically through the hollow shank of the spindle. More specifically, in such an instance the cylindrical body may in the form of a hollow paraboloid of rotation be placed upon the hollow spindle shank and have its jacket provided with a helical groove provided at least at its upper third with passages through which a wetting agent, a finishing or brightening agent or the like received by the hollow paraboloid of rotation may be released onto the thread engaging the paraboloid of rotation.
When the helical groove rises in the direction of rotation of the entering thread or yarn, the helical groove aids in the withdrawal of the thread, while the threads absorb the wetting agent or the like which passes through said passages in the jacket within the range of the helical groove. The helical arrangement of the passages assures a uniform thread weight, whereas the helix itself brings about a uniform movement of the thread and thereby also a uniform wetting of the thread.
In particular instances it has proved advantageous to provide the helix of the jacket of the paraboloid of rotation so that the helical groove runs counter to the direction of rotation of the thread in a rising manner. This likewise improves the movement of the thread. A certain braking of the thread will occur which improves the engagement of the thread with the paraboloid of rotation and thereby also improves the absorption of wetting `agent or the like.
According to a further development of the invention, the hollow paraboloid of rotation may be provided with a transverse wall and in the plane of said Wall may have a protruding step with partial annular slots on the surface. Wetting agent or the like may be filled into the container through said partial slots whenever the supply in said container runs low. Thus, each paraboloid of rotation may have associated therewith a supply nozzle connected to a central conduit for filling wetting agent, finishing or brightening agent or the like into the container.
A still further development of the invention consists in placing the paraboloid of rotation in an axially resilient manner upon the hollow shank of the spindle so as to be able to yield somewhat in case of differences in the thread tension whereby the thread tension will remain substantially uniform. This likewise contributes to a uniform movement of the thread and permits the paraboloid of rotation which releases the wetting agent, finishing or brightening agent or .the like, to aid in an improved manner in the smooth movement of the thread.
Referring now to the drawings in detail and FIG. 1 thereof in particular, the arrangement shown therein comprises a two-for-one twisting spindle in which the bobbin disc 3 supports a bobbin 4 placed upon a bobbin spindle or bobbin sleeve 5. Bobbin disc 3 is in customary manner located above the turntable (not shown in the drawing). Bobbin 4 is located within a protective basket 6. As will be seen from the drawing, bobbin sleeve 5 is provided with an axial thread passage 7 and has a cylindrical recess 8 at its upper end. Inserted into said upper widened end of passage 7 is a tubular member 9 forming the spindle shank. Tubular member 9 forms that end of spindle shank generally designated 10, which extends above bobbin 4.
In conformity with FIG. 1, a slidable bushing 11 is placed upon the hollow spindle shank 9 and is provided with a radially extending liange 12. Bushing 11 is supported by a pressure spring 13 which extends downwardly into the cylindrical recess 8 of bobbin sleeve 5 and rests upon the body 14 of said recess. Flange 12 supports a cylindrical body 15 consisting of a finishing substance, brightening substance or the like, said cylindrical body 15 surrounding tubular member 9. The upper end face 16 of cylindrical body 15 has `a conical contour so that said contour corresponds approximately to the shape of a body of rotation described by the thread or yarn 17 being withdrawn from bobbin 4. Cylindrical body 15 is surrounded by a bushing 26 extending downwardly into recess 3 and by means of step 27 resting upon the upper edge of bobbin sleeve 5. The upper edge of bushing 26 is rounded and serves in guiding thread 17 passing thereover while primarily determining the conical shape of end face 16 of cylindrical body 15.
When thread 17 is being withdrawn from bobbin 4 in upward direction in the manner illustrated in FIG. 1, it will at the upper end face 18 of tubular member 9 be deviated downwardly and move through the axial bore 7 downwardly to the thread storage disc. During this operation, thread 17 will contact the upper end face 16 of cylindrical body 15 consisting of hard finishing or brightening substance and will absorb said substance whereby the thread is smoothed and made more flexible. Cylindrical body 15 will continuously be raised to the extent to which finishing or brightening substance or the like is absorbed by thread 17 from cylindrical body 15. In this way, cylindrical body 15 consisting of finishing substance, brightening substance or the like can approximately be entirely used up. Cylindrical body 15 will assure a thread treatment over a long period of time and has relatively only seldom to be replaced by a new cylindrical body of hard finishing or brightening substance.
It is, of course, to be understood that the body 15 composed of hard finishing or brightening means may also be screwed onto the upper end of bobbin sleeve 5, and this screw connection may be changed manually from time to time in conformity with the withdrawal substance from said body.
While FIG. l shows cylindrical body 15 as being supported by spring 13 so that said body 15 will automatically rise in conformity with the consumption of body 15, it is, of course also possible to arrange the cylindrical body 15 stationarily and to make the upper end of spindle shank 9 axially displaceable by supporting the same by a spring or the like. In this way, the upper end of spindle shank 9 will be pressed downwardly against the thrust of spring 13 by the thread tension in conformity with the consumption of the end face 16 of body 15.
Referring now to FIG. 2, the arrangement shown therein differs from that of FIG. 1 primarily in that the cylindrical body generally designated 25 forms an annular cup 24 placed upon spindle shank 10 and forming a part of bobbin sleeve 5, and also placed upon hollow shank 9 forming an extension of spindle shank 10. Cup 24 has a shoulder 20 by means of which it rests on bobbin sleeve 5. As will be seen from the drawing, cup 24 extends downwardly into a cylindrical recess 8i. The interior of cup 24 contains a liquid wetting substance or liquid finishing or brightening substance 23. Cup 24 has its top closed by a closure member 21 of absorptive material such as natural sponge material, natural porous material, felt, felt mate, felt cushion, polyurethane foam, foam plastic material, synthetic porous material, plastic foam, expanded plastic material, and the like. Partly located in and extending from closure member 21 is a plurality of wicks 22 which extend to the bottom 19 of cup 24. Wicks 22 absorb wetting substance or finishing or brightening substance so that closure member 21 is continuously saturated therewith and is adapted to yield wetting substance or finishing or brightening substance or the like to thread 17. Upper end face 16 of closure member 21 is of a conical contour similar to the upper end face of cylindrical body 15 of FIG. 1. Thus, also the upper end face of closure member 21 is in conformity with the shape of a body of rotation as will be described by thread 17 being withdrawn from bobbin 4. It will thus be assured that the closure member 21 is saturated continuously with a wetting substance and that the wetting substance is transmitted to thread 17 passing over end face 16 of closure member 21. It will also be appreciated that in addition to continuously suppling a wetting, finishing or brightening agent to thread 17 being withdrawn from bobbin 4, the supply of said substance is effected at the most sensitive portion of the thread path, viz. where the thread is greatly deviated and enters spindle shank 9.
When the wetting agent or the like in cup 24 has been nearly consumed, no difficulty exists in refilling said cup. Due to the fact that the wicks extend approximately to the bottom of cup 24, the wetting substance can practically be used up completely.
Referring now to FIG. 3, only the upper end of bobbin 4 is shown. In the arrangement of FIGS. 3 to 6, hollow spindle sleeve 9 extends axially through bobbin 4. A hollow paraboloid of rotation generally designated 28 is placed upon hollow spindle shank 9. The outside of said paraboloid 2S, and more specifically, its jacket 30, is provided with a helical groove 29 which rises in a direction opposite to the direction in which the thread 17 circulates. At about the upper third of said jacket 30, the paraboloid 28 is within the range of helical groove 29 provided with passages 31. The interior of paraboloid 28 is by means of a transverse partition 32 subdivided into a lower chamber 33 and an upper chamber 34. Upper chamber 34 is filled with an absorptive material 35, for instance an absorptive foam material or the like, as described above in connection with FIG. 2. The lower chamber 33 contains a liquid wetting substance 36 which by means of one or more wicks 37 is drawn upwardly through partition 32 so that the absorptive material 35 will be currently saturated with a wetting substance of a finishing substance, brightening substance, or the like. Lower chamber 33 serving as storage -chamber for the wetting agent or the like thus currently conveys wetting substance or the like through passages 31 onto the circulating thread 17 which engages jacket 30 at least along the upper curved surface of paraboloid 28. At the same time, the circulating thread 17 causes a suction effect thus aiding the discharge of wetting substance or the like from the interior of chamber 34 through passages 31.
In conformity with FIG. 3, jacket 30 of paraboloid 28 extends uniformly and step-free from the top toward the bottom. The bottom is provided with a depression 38 having an opening 40 covered by an elastic valve hose section 39. Hose section 39, while covering opening 40, still permits the entry of wetting agent or the like by means of a pump into storage chamber 33 for filling the same.
The arrangement shown in FIG. 4 differs from that of FIG. 3 in that the spindle shank 9a is within the range of upper chamber 34 curved in opposite directions a plurality of times. Furthermore, radial bores 49 are provided in shank 9a to establish communication between the interior of hollow spindle shank 9a and chamber 34. Wetting agent or the like passes through bores 49 from the wetting agent permeated material 35 into spindle shank 9a and distributes itself along the inner surface thereof while this distribution is aided by the vertically moving thread 17. This is particularly so because thread 17, due to the curvatures 9b and 9c of shank 9a, will positively engage the inner wall surface of shank 9a at a plurality of places and will thus pick up wetting agent or the like from said inner wall surface of shank 9a and will at the same time distribute said wetting agent uniformly over said wall surface.
According to the embodiment of FIG. 5 paraboloid 28a is along the plane of partition 32 provided with a step 41 which at the upper side has partial annular slots 42 through which wetting agent 36 or the like can be filled.
Furthermore, according to FIG. 5, below paraboloid 28a there is provided a disc 43 spaced from the bottom of said paraboloid. The outer marginal portion of disc 43 protrudes beyond the outer circumference of paraboloid 28a. Within the plane of disc 23 there is provided at least one radial bore 44 which communicates with the interior of spindle shank 9 so that wetting agent or the like received by disc 43 will be able through passage or passages 44 to pass into the interior of spindle shank 9 and to additionally moisten thread 17 vertically passing through shank 9.
As will be evident from FIG. 5, the filling of lower chamber or reservoir 33 with wetting agent or the like, and the charging of wetting agent or the like onto disc 43 is effected by means of a pigtail-shaped tubular thread guiding member 45. The free end of member 45 forms an eccentrically downwardly directed drip-nozzle 46 releasing the wetting agent or the like. The drops 47 released by member 45 first hit the curved outside of paraboloid 28 and flow partly on said outside surface and partly in helical groove 29 `downwardly to step `41 where they pass through slots 42 into the interior of chamber 33 thereby supplementing the wetting agent or the like in reservoir 33. A portion of the wetting agent or the like passes over step 41 `or through helical groove 29 further downwardly to the lower outer marginal portion of paraboloid 28. From he-re the said substance drops onto disc 43 which passes the wetting agent or the like through radial bores 44 into the interior of spindle shank 9 where an additional wetting of the thread passing vertically through shank 9 will occur.
The embodiment illustrated `in FIG. 6 differs from that of FIG. 5 primarily .in that it lacks step 41, Vand that between disc 43 and the bottom of paraboloid 28 is filled with an annular disc or the like 4S of absorptive material. This disc is adapted to store the wetting .agent or the like which collects on disc 43 and to release said wetting agent or the like uniformly through bores 44 into the interior of spindle shank 9 and thereby to thread 17 in the interior of shank 9. This arrangement makes the entry of wetting agent or the like into the interior of the spindle shank more uniform.
The arrangement of the protruding step as well as the arrangement of disc 43 with or without absorptive material below paraboloid 28, 28a makes it possible at a standstill of the spindle automatically to refill reservoir 33 with wetting agent, finishing agent, brightening agent or the like.
It may also be mentioned that the pigtail-shaped mem- 6 bers `45 of all or a plurality of spindles may be supplied from a common supply pipe. In this instance, each member 45 would have associated therewith metering valves.
As will be evident from FIGS. 3 to 6, paraboloid 28 greatly raid-s in the smooth movement of thread 1`7 being withdrawn from the bobbin, and furthermore forms a body furnishing wetting agent or the like to thread 17 while in conformity with FIGS. 4 to 6 an additional wetting of thread 17 may be effected while said thread passes through the interior of hollow shank 9.
It is, of course, to be understood that the present invention is, by no means, limited to the particular embodiments of the invention illustrated in the accompanying drawings, but also comprises any modifications within the scope of the appended claims. Thus, if desired, paraboloid 28, 28a maybe axially resiliently located on spindle shank 9 in order to be able to yield to a certain extent when differences in the tension of the thread should occur. In this way, the `thread tension will remain approximately uniform. Moreover, such an arrangement also contributes to a uniform passage of the thread.
It may also be added with respect to FIGS. 1 and 2 that the upper end contour of bodies 16 and 21 need not precisely be predetermined in conformity with the contour of the body of rotation described by thread 17 being withdrawn from .bobbin 4, but that the said upper end contour will shape itself in view of thread 17 carrying off the material of bodies 16, 21.
lt is furthermore to be understood that the term thread treating means as it appears in the claims covers any solid as well as liquid thread treating means employed in connection with the tre-ating of threads being spun.
