PAY-OFF GUIDE FOR COIL HOLDER Earl J. Romig, Monongahela, Pa., assignor to United States Steel Corporation, a corporation of New Jersey Application February 11, 1955, Serial No. 487,550

Claims. (Cl. 242-129) This invention relates to a guide for supporting a coil of rod or wire on a holder from which it pays off.

Rose Reissue Patent No. 22,172, dated September 1, 1942, shows a coil holder which has three sets of radially extending upper and lower arms, each set being adapted to support a separate coil of wire or rod in an upright position. The wire or rod from one coil pays oif to some other equipment, for example a wire drawing machine, and the trailing end of this coil is attached to the leading end of the next to permit continuous operation. The guide of the present invention is especially suited for use on a coil holder of such construction, although obviously it can be used on holders whose details vary from this patent.

An object of the invention is to provide a guide which is adapted to support a coil on the upper arm of a coil holder of the foregoing type and to prevent tangles and assure that the wire or rod pays off smoothly.

A further object is to provide a guide in the form of a saddle which rests on the upper arm of such a coil holder and has a curved coil supporting surface conforming with the inside surface of a coil and ribs adapted to separate the coil convolutions.

In accomplishing these and other objects of the invention, I have provided improved details of structure, a preferred form of which is shown in the accompanying drawing, in which:

Figure l is a side elevational view of a coil holder similar to that shown in the Rose patent equipped with a guide constructed in accordance with my invention;

Figure 2 is a side elevational view of my guide on a larger scale; and

Figure 3 is a top plan view on a scale similar to Figure 2.

Figure l shows a coil holder which comprises a pedestal 10, an upright shaft 12 supported on the pedestal, and a sleeve 13 journaledon this shaft. The sleeve carries a plurality of sets of radial upper and

lower arms

14 and 15 which are of U-shape in plan and are pivoted thereto on horizontal axes. Links 16 extend between the upper and lower arms of each set, being pivotally connected to the respective arms. The pivot of each link to its upper arm 14 is located outwardly of the pivot of this arm to the sleeve 13, while the pivot of each link to its lower arm 15 is located inwardly of the pivot of the latter arm to said sleeve. Thus the arms tend to pivot in opposite directions to enable them to be brought together so that a coil W can be mounted thereon, or spread to hold the coil. Counterweighted pawl levers 17 are pivoted to the sleeve 13 and carry pawls 18 which normally engage notches in the links 16 to hold the arms in their spread position. The upper end of sleeve 13 carries a bracket 19 to which flipper members 20 are pivoted, one above each upper arm 14. Guards 21 extend downwardly from the lower arms 15. The flipper members 20 and guards 21 cooperate to guide the wire so that it pays off one convolution at a time. Reference can be made to the Rose patent for a more complete showing of a holder of this type.

2,819,854 Patented Jan 14, 1958 The guide of my invention is interposed between an upper arm 14 and a coil W. Although Figure 1 shows only one such guide, it is contemplated that the arms all would be similarly equipped. My guide comprises an elongated'sheet metal saddle 22 which has inner and

outer extensions

23 and 24 at its respective ends. The saddle has a smooth upper face and is of arcuate cross section diverging outwardly. The inside faces of the U-shaped upper arm 14 carry keepers 25 and the saddle carries downwardly extending legs 26 which fit within said keepers. The inner portion of the saddle and the inner extension 23 fit within the U-shaped arm to cooperate with the legs in positioning the guide. The saddle covers the outer portion of the arm and slopes upwardly and outwardly at a relatively small angle, for example about 15. The outer extension 24 is of arcuate cross section and slopes at a steeper angle, for example about 30. The saddle carries a plurality of pivotally mounted wire or rod ribs 27 which extend across its upper face. These ribs extend outwardly from their pivotal mountings and are of a curvature to conform with the saddle. The ribs enter the coil between convolutions thereof and assist in preventing the convolutions from tangling.

In operation, guides of the foregoing construction are installed on each of the upper arms 14 of a coil holder. The coils W are placed around the upper and

lower arms

14 and 15 in the usual manner, and the flipper members 20 lowered against the saddle. The inside of the coil rests on the saddle 22, and the curvature of the portion paying oil conforms with that of the saddle. Thus the wire is guided smoothly over the saddle and its outer extension 24. The ribs 27 further assure that the convolutions remain in order as they pay off.

While I have shown and described only a single embodiment of my invention, it is apparent that modifications may arise. Therefore, I do not wish to be limited to the disclosure set forth but only by the scope of the appended claims.

I claim:

1. A guide for supporting a coil on a holder in an upright position to enable it to pay off comprising an elongated saddle of arcuate cross section diverging outwardly, means on the underside of said saddle for positioning it on a holder, a plurality of ribs on the upper face of said saddle adapted to fit between convolutions of the coil, and an extension of arcuate cross section projecting upwardly and outwardly from the outer end of said saddle.

2. A guide for supporting a coil on a holder in an upright position to enable it to pay ofi comprising an elongated smooth-faced sheet metal saddle of arcuate cross section diverging outwardly, means on the underside of said saddle for positioning it on a holder, a plurality of ribs pivoted to said saddle and extending across the upper face thereof and adapted to fit between convolutions of the coil, and a smooth-faced sheet metal extension of arcuate cross section projecting upwardly and outwardly from the outer end of said saddle.

3. The combination, with a coil holder which includes an arm adapted to support a coil in an upright position to enable it to pay off, of a guide for the coil comprising an elongated saddle of arcuate cross section diverging outwardly, means on the underside of said saddle positioning it on the top of said arm, a plurality of ribs on the upper face of said saddle adapted to fit between convolutions of the coil, and an extension of arcuate cross section projecting upwardly and outwardly from the outer end of said saddle.

4. The combination, with a coil holder which includes an arm adapted to support a coil in an upright position to enable it to pay off, of a guide for the coil comprising an elongated: smooth-faced sheet metal saddle of arcuate 7 cross section diverging outwardly means onthe under side of said saddle positioning it on the top of said arm. a plurality of ribs pivoted to said saddle and extending across the upper face thereof andadapted tobetween convolutions ofaoil and a smooth-faced sheet metal extension of arcuat'e cross section projectin'gupwardly and outwardly from the outer end ofsaid saddle.
