RING CLEANING APPARATUS Filed March 6, 1968 INVENTOR. BOBBY L. PITTS F/G.-4- Mam ATTORNEY United States Patent f Int. Cl. D01h 11/00 US. CI. 57-57 3 Claims ABSTRACT OF THE DISCLOSURE Apparatus for automatically removing accumulated fibers from the traveler on a ring spinning frame by creating an area of differential pressure to suck and remove the fibers from the travelers.

Prior to this invention considerable effort has been expended on methods and apparatus to clean lint, waste, etc., from the travelers on a ring spinning frame, twisting frame or the like. A number of these methods involved mounting a device in the path of travel of the traveler as it rotates around the ring to physically contact the lint accumulated on the traveler. These devices, in some instances, performed satisfactorily but also had some undesirable features. One of the basic undesirable features was that the device had to be critically located with respect to the rotating traveler and in many instances was not properly located or was accidentally moved resulting in either not cleaning the traveler at all or being too close to the traveler and being hit, thereby bringing the yarn end down and/or causing damage to the traveler.

Therefore it is an object of the invention to provide a traveler cleaner which will efficiently clean the traveler without damage thereto.

Another object of the invention is to provide apparatus to clean the traveler of a ring spinning frame which does not depend on direct physical contact with the accumulated lint on the traveler.

A still further object of the invention is to provide a means to automatically and pneumatically clean the accumulated lint on the traveler of a ring spinning frame.

Other objects and advantages of the invention will be clearly apparent as the specification proceeds to describe the invention with reference to the accompanying drawing in which:

FIGURE 1 is a schematic partial perspective view of a ring spinning frame;

FIGURE 2 is a blown-up perspective view of the preferred traveler cleaner;

FIGURE 3 is a modification of the traveler cleaner shown in FIGURE 2; and

FIGURE 4 shows a modified method of forming the negative pressure chamber.

Looking now to FIGURE 1 the new and improved traveler cleaner is shown in operative relationship with a conventional spinning frame 11 in which roving 12 is delivered from roving bobbins 14 to a drafting system 16 wherein the fibers are drafted. The drafted fibers are then delivered to the rotating take-up bobbin 18 through pig tail guide 20 and rotating traveler 22. Twist is inserted in the yarn between the nip of the front rolls 24 and 26 of the drafting system 16 and the rotating traveler 22. Bobbin 18 is mounted on a conventional spindle 28 which is driven by a drive tape (not shown) which contacts the whorl 30.

In the preferred form of the invention shown in detail in FIGURE 2 the traveler cleaner 10 consists of a ring holder portion 32 and an annular upstanding wall por- Patented Dec. 9, 1969 ice tion 34 which provides an annular chamber 36 between the inside of the wall portion 34 and the ring 38 snugly secured in the ring holder portion 32. The traveler 22 is snapped over the flange 40 of the ring 38 and is guided thereby in its rotary path.

The traveler cleaner 10, preferably, is molded as a unit and has an annular projection 42 molded thereon to engage the bottom of the ring rail 44 when the traveler cleaner 10 is snapped into an annular opening in the ring rail 44. If desired the annular projection 42 can be a separate member such as snap ring or annular spring which is placed around the circular portion 46 of the ring holder portion after it is projected through the annular opening in the ring rail 44.

In operation in conventional manner, the traveler 22 is pulled around the ring 38 by the rotation of the bobbin 18, thereby putting twist in the yarn between the front drafting rolls 24, 26 and the traveler 22. As the traveler 22 rotates around the ring 38 it causes the yarn to form a balloon 48. The centrifugal forces created by the rotation of the balloon in turn pulls air through the opening 50 between the bobbin 18 and the traveler cleaner 10. As this air passes over the top of the ring flange 40 and the top of the annular cavity 36 a negative pressure is created in the cavity 36 which causes air to be pulled into the cavity 36 at points 52 and 54 and pulled out by the action of the centrifugal forces created by the rotation of the balloon 48. It can be readily seen that any lint or waste which accumulates on the traveler will be sucked off when the traveler enters the cavity 36 because of the differential pressure or suction effect created in the cavity by the air flow across the top of the upper wall portion.

It should be noted that the outside side wall of the upper portion 34 of the traveler cleaner is tapered outwardly from the top to minimize the accumulation of lint, etc., thereon.

Looking now to FIGURE 3 a modified traveler cleaner is shown. The principle of operation of FIGURE 3 is substantially the same as that of FIGURES 1 and 2 except instead of the upper wall portion being in one continuous piece to form one continuous differential pressure cavity, the upper wall portion is composed of a plurality of members 56 forming a plurality of cavities 58. Each of these cavities perform in a manner similar to cavity 36 in that lint, etc., on the traveler will be cleaned therefrom because of the suction effect created in the cavities 58.

FIGURE 4 shows a further modification of FIGURES 1 and 2 which also can be applied to the modification of FIGURE 3. Rather than have the upper annular wall members integral with the ring holder, holes 60 can be drilled or otherwise formed in the top surface of the ring holder and pegs 62 formed on the bottom of the upper annular wall member which conform to the size of the holes formed in the ring holder.

Looking at the above disclosure it can readily be seen that the herein disclosed traveler cleaner cleans the traveler without actually contacting the traveler. Furthermore, once the disclose-d traveler cleaner is properly installed there is nothing attached thereto which can be accidentally dislodged by an operator to cause a malfunction. Also, it is readily obvious that the herein disclosed traveler cleaner is relatively simple to fabricate or mold at a nominal price.

That which is claimed is:

1. Apparatus to clean lint from a traveler on a ring and traveler frame comprising: a ring holder having openings in the upper surface thereof, a ring secured in said holder, a traveler operably associated with said ring and means separate from said holder surrounding a portion of said. ring to form a chamber therebetween and having projections on the bottom thereof projecting into said openings in said ring holder to thereby hold said means in proper position.

2. A ring and traveler textile frame comprising: a frame, a ring rail in said frame, a ring holder projecting through an opening in said ring rail, a ring mounted in said ring holder, a traveler operably associated with said ring, an upstanding annular Wall member integral with said ring holder and surrounding a portion of said ring and spaced therefrom to form a chamber therebetween and locking means operably associated with said ring holder to hold said ring holder in position in said ring rail.

3. The structure of claim 2 wherein said locking means is integral with said ring holder.
