Lakewood, Ohio, assignor to Wire Company of New 13 Claims. ((71. 242-128) The present invention provides an improved apparatus for continuously supplying wire to various processing treatments, such as galvanizing, tinning, or annealing, the apparatus being designed to supply the wire smoothly and free from kinks, twists, or other distortions.

In wire processing, such as those mentioned above, and also in the production of wire products, such as wire fencing and other wire products, considerable time may be lost by the processing equipment being shut down during replenishing of bundles of wire thereto, thus resulting in low machine efficiency. In accordance with heretofore practice, the actual machine shutdown time has been approximately 30% to 50% of the operating time, and from approximately 60% to 80% of the machine down time was caused by replenishment of bundles of the wire being processed. For operation of the machines, one of the requisite requirements for a continuous supply of wire is that the last and of the preceding bundle must be welded to the first end of a successive be a continuous supply of wire for processing thereof.

One of the objects of the present invention is to provide an improved type of continuous payoff reel, which permits the above-mentioned welding of the bundles and thereby eliminates the period of shutdowns caused by the necessity of restringing the processing equipment for each bundle of wire used.

A further object of the invention is to provide such a payoff reel which can be located readily and from which the wire is drawn free from kinks or other distortions.

Other objects of the invention will become apparent as the description proceeds, and the features of novelty will be pointed out particularly in the appended claims.

The invention will be understood more clearly by reference to the accompanying drawings in which:

Fig. 1 is an elevational view of one form of the reel in unloaded condition, but with a bundle of wire in position to be lifted onto the reel.

Fig. 2 is a view similar to Fig. 1, but showing the reel with a bundle of wire partly positioned thereon.

Fig. 3 represents a fully-loaded reel, with wire from the bundle ready to be used at a remote processing station.

bundle in order for there to Referring more particularly to the drawings, reference character A designates a hanger or reel which is adapted to be suspended vertically and to receive a coil or bundle of wire which is fed to the processing machine by means of feeding means B. p

The" reel A comprises pairs of fixed .arms i, which are secured to, and depend from, arms it of a top spider 9 beneath a top plate Iii, which arms may be secured at their bottom endsby a cup-shaped holder ii, Figs. 5 and 8, and between which pairs of arms are hung swinging arms iii, which are hung freely on pivot shafts l3 which are mounted in the opposite fixed arms of each pair thereof. Three of these arms are illustrated, although the specific number thereof is not critical, and each one of the swing arms is provided with an outwardly extending lug or fin I! which is cam-surfaced, each lug flaring outwardly from its bottom to its top, so that the bottom is almost pointed and the top is a web of sufiicient width to hold a bundle of wire i9 positioned on the reel.

A sleeve M ,of a mounting bar 21a projects centrally through the plate l0 and well into the interior of the reel to receive a spider 20 having

arms

22, 2d, and 26 extending radially thereof,

r each of the arms having a pair of branches, such as indicated at 2B, 30, which have "enlarged heads- 32, 34 for reinforcing the fixed arms I of the reel, which are secured to the

heads

32 and 36 by screws 36. The swinging arms i5 swing freely between these heads, or brackets, 32 and 35. A nut 23 is threaded onto the inner end of the bar 2m and bears against the underside of the spider casting 20.

The sleeve 2| maybe hollow, and projects outwardly to a substantial extent beyond the plate I ID, the outer end of the an eccentric planetary arm tary arm 3| is a part of bar 2ia being capped by a nut 25.

The outer by a revolving sleeve-shaft 21, projecting bracket arm 29 to which is mounted 2| of the feeding portion of the bar 2: is enclosed mechanism B.

The shaft 21 is provided I between its inner wall and the bar 2la, the inner wall of shaft 21 being'recessed suitably to seat the bearings. retaining member for the top bearing 35.

Shaft 21 is a casting which is cast with one end of the shaft flaring outwardly at 31 into a bell-shaped opening, and then into the flanged portion 39, which receives a self-aligning bearing ",this being held in place by retaining means 43 bolted by bolts 45 to a flange 41 in a hanger 40 which encloses the end of the shaft assembly described above, This hanger 49 is bolted to flange 1 by bolt 45, and to a plate which substantially closes the bottom of the frame, but which has a hole therethrough for the passage of the shaft 21.

The hanger 49 serves also as a mounting for a sheave. 53 over which wire from the bundle on the reel is passed on its way to the processing machine.

It has been said above herein that the planethe wire feeding means. The arm 3| is provided with a series of'spac'ed loop carriers 55 through which the wire, indicated at 51, is threaded. The feeding means are completed by a block thereof, the mounting being effected by a bolt 83. The block 59 extends into the bell-mouth of the shaft 24 and has a conical opening therethrough, the apex hole being on the vertical axis of the block, and is at the center of rotation of the arm 3|; and the sheave 53 is positioned sd as to be tangent to the center line of this hole. Therefore, the wire 51 does not become disengaged from the sheave 53 as the arm 3| revolves around the reel.

The entire apparatus is suspended suitably, such as, for instance, from a beam 81 by a hanger 49.

In operation, suppose, for example, two 300 lb. bundles of wire are welded together on a cradle 1| on a loader truck 13. The truck and loaded cradle then are taken to a position beneath the empty payofl' reel A, as will be seen from Fig. 1. The bundle of wire I 9 is placed on the reel A by raising athe cradle H by means of hydraulic piston 15. a

In the modified form of the reel as shown in Figs. 5, 6, 7, and 8, and which is the preferred form, the cup-shaped or conical nose ll of the reel enters the central hole of the bundle of wire, and guides the bundle onto the hooks or fins H, as the cradle H continues to be raised. The

cam contour of the hooks I! forces the swinging arms l5 inwardly, thereby allowing the bundle to be seated on the hooks or flns II, which then return by gravity to their natural supporting position. The cradle then is lowered and' the bundle rests on the supports (Figs. 3 and 4) is inserted to prevent rotation of the entire reel. The top end of the bundle then is threaded through the loops 55 on the arm 3|. thence over sheave 53 and then to the processing machine which then is-started. Tension on the which carries a with bearings 33 and The nut 25 also serves as a 59 which is mounted on the planetary arm 3| adjacent to the upper end 6i 1 I1, and a brake 11" illustrated in Figs. 1

strand of wire 57 as it is pulled by the machine through the loops 5! causes the arm 3| and its mounting assembly to turn, so that the arm 3| revolves around the reel A, paying oil. the wire from the bundle as the arm revolves.

As the amount of wire on the reel A becomes depleted from the bundle is, say, for example, after about 400 to 500 lbs. of wire'have been .used by the processing machine in order to recradle beneath the reel. The last end 18 of the bundle I9 on the payoil reel is welded to the top end 80 of the bundle 82 on the loader, as is indicated at 19 on Fig. 4, and the cradle then is raised. The bundle in the cradle forces inwardly the swinging bundle supports I! and releases the brake 17, thereby allowing the remainder of the bundle on the payofi reel to rest on the buntion.

As the bundle is lifted onto the supports H, the conical member I l acts as an entry nose. it entering the hole in the center of the bundle of wire and guiding the convolutions of the wire onto the supports I 1. The member II also assures the proper guidance of any bundle onto the swinging supports l1, preventing thereby the points of these supports entering the bundle of wire between the turns of the strand of the wire if the bundle should happen to be loosely wound, which possibility tends to make the form of the device to 4, inclusive, somewhat less desirable'than the other modification shown on the drawings. I

It will be seen, therefore, that the device of the present invention provides a simple carrying and unwinding mechanism for coils of wire, which mechanism greatly facilitates joining together the ends of successive bundles of wire to provide a continuous supply thereof, without requiring shutdown of the equipment for reloading.
