United States Patent Office 3,520,493 Patented July 14, 1970 3,520,493 GUIDE FOR A MOVING TEXTILE STRAND Robert L. Carroll, 408 McIver St., Greenville, S.C. 29601 Filed Oct. 18, 1968, Ser. No. 768,731 Int. Cl. B65h 57/00, 57/24, 57/26 U.S. Cl. 242157 4 Claims ABSTRACT OF THE DISCLOSURE This invention relates to a guide for a moving textile strand useful on a creel and the like, which employs a loop for easy threading.

Heretofore, on creels and the like, such as employed on beamers and Warpers, a bar has been employed having closed eyelets constructed of wear resistant material therein. It has been necessary for operators to draw in broken ends through the eyelets in a number of succeeding bars in the creel. Such is very laborious and time consuming, resulting in considerable machine down time. This simple operation thus occasions inordinate difiiculty and expense.

Accordingly, it is an important object of this invention to provide a yarn guide for a creel which may be easily threaded in a single motion.

Another important object of this invention is the reduction of labor and down time in operating textile strand manipulating machines, such as beamers and warpers.

Still another important object of this invention is to re duce down time and expense in the creeling of a loom beam and the like.

Another object of the invention is the provision of a yarn guide which may be easily adjustable laterally.

The construction designed to carry out the invention will be hereinafter described, together with other features thereof.

The invention will be more readily understood from a reading of the following specification and by reference to the accompanying drawing forming a part thereof, wherein an example of the invention is shown, and where- 1n:

FIG. 1 is a schematic side elevation illustrating a creel used in connection with a beamer, equipped with a strand guide constructed in accordance with the present invention,

FIG. 2 is a perspective view taken on the line 2--2 in FIG. 1 illustrating a strand guide constructed in accordance with the present invention at an enlarged scale,

and

FIG. 3 is a transverse sectional elevation of the strand guide taken on the line 33 in FIG. 2.

The drawing illustrates a guide for a moving textile strand useful on a creel and the like including a bar A. The bar has a strand guiding surface thereon, disposed across the strand and being constructed of wear resistant material. A support B is carried by the bar. A strand guiding loop C is disposed across each of the strands and is constructed of wear resistant material, said loop being open at one end thereof and being fixed at the other end ot the support. A longitudinal trackway D, illustrated in the form of a slot, is carried by the bar. A guide E is carried by the support for longitudinal adjustment on the trackway, and means is provided for spacing the loop from the bar. Fastening means F are provided for fixing the support on the bar. The loop is preferably hookshaped, presenting a strand opening on one side of the strand guiding surface. One end of said loop extends across the strand guiding surface.

A creel, broadly designated at 10, is illustrated as carrying yarn packages 11. The yarn guides of the present invention are mounted on vertical frame members 12 on each of the sections of the creel 10. A vertical frame member 13 is illustrated as being positioned on a succeeding section of the creel 10. The strands of yarn Y are illustrated as being carried to a conventional eyeboard 14 of a beamer, carried by a forward extension of the frame 15 of the beamer. The yarn then passes through a comb 16 and over a roll 17 to a section beam 18. Motive power is provided for driving the beamer by a motor 19. If desired, the yarn guide of the present invention may be adapted to replace the eyeboard 14.

The bars A are best illustrated in FIGS. 2 and 3, and each includes a face 20 for carrying the supports B, as well as an upper surface 21 which serves as a strand guiding surface on the bar disposed across the strands Y. The upper surface 21 may be plasma coated as illustrated by the stippling 22. While plasma coating is preferred, any other suitable Wear resistant material may be employed.

A strand guiding loop C is disposed across each of the strands constructed of suitable wear resistant material, preferably ceramic material, such as Heanium. Heanium is the trademark of Heany Industries, Inc., 915 Whitney Ave., New Haven, Conn. Each of the loops C is hookshaped and at one end has a depending leg 23 connected by a curved portion 24 to a second depending leg 25 at the other end which is secured to its respective support B. Thus, the loop is substantially U-shaped. The loops C are preferably integral with respective supports B which are also constructed of Heanium.

A longitudinal trackway D is carried by each of the bars, and is formed by a plurality of slots having uppper and lower surfaces 26 and 27, respectively.

A guide E is formed by a protuberance on each side of the support B having parallel upper and lower surfaces 28 and 29, respectively. Each support has a bore 30 in the central portion thereof for accommodating a threaded shank 31 of a screw. The fastening means, including the screw, is designated by the letter F. The head of the screw is illustrated at 32, and an internally threaded nut 33 secures the screw carrying the support B to the bar A. A washer 34 may be provided, if desired, between the nut 33 and the bar A on the back 20a opposite the face 20. The support has a portion 35 on each side thereof which projects outwardly beyond each of the loops C forming a means spacing each loop from its respective bar.

It will be noted that the bars on each side of the creel carrying loops opening outwardly toward the adjacent aisle so threading can be accomplished by a single inward movement of the strand over the bar, and under the freeend of the loop. Since the portions 35 are on each side of each support, any support and loop unit may be used on either side of the creel with the loop opening outwardly. If desired, the bars may be inverted at the upper portion of the creel and threaded from below. As will be noted in FIG. 2 the strands run in some instances on the guiding surface 21 and in other instances in the loop, depending on the direction of the strands.

While a preferred embodiment of the invention has been described using specific terms, such description is for illustrative purposes only, and it is to be understood that changes and variations may be made without departing from the spirit or scope of the following claims.
