Appnctin mea December 12, 1924. seriarNo; 755,585.'

The inventionrelat to racks or boxes in which a coil of strip steel or the like may be carried. for unwindinggto pass contlnu.- ously througha rolling mill, an anneallng apparatus, or for other endwise o erations on the strip; and the object of the lmprovement is to connect a plurality of coil carryso that either one of the boxes may be moved alternately into and out ofalinement with the o rat-ind a aratus. v

A Edil ofbstrri; steel is very heavy and cumbersome to handle and tol properly position by manualmeans, especially, when the coiled strip has a length ofa hundred feet or more'gand a width of some twenty inches, as in recent practice; and before proceeding with a continuous endwise operation upon the strip, the coil must be properly positioned in exact aline'ment w1th the operating apparatus, and it is frequently necessary to cut or trim' or otherwise work upon the forward end of the-strip before 1t can properly enter the apparatus.

Furthermore a series of strips are frequently woun one upon another, which makes a very heavy coil and whenv the 'suC- 'cessive strips aren unwound forrolling it is frequently necessary to cut the fish-tail from the next coil before it can be processed.

For the purpose of facilitating the han- .dling of such a coil, and for rapidly bringing it in proper position and exact condition for aV continuous operation upon the strip, the' present improvement consists in joining tworor more individual boxes side by side to form a common carrier, and in mounting the same upon a track or bearlng for alternately shifting either one of theboxes into proper position for unwinding a coil therein, and another box in.A proper position for receiving a `fresh coil and preparing it for a continuous operation.

' A preferred form of the invention and some modifications thereof are illustrated in the accompanying drawings, forming part hereof, in which- Figurel is a plan view of the improved box carrier in conjunction with a train of rolls; Fig. '2, of the coil box carrier; A

a side elevation partly in- .section-Y fFig.' 3, a plan view of the same with the .i i

pit cover removed;v

Flg. 4, a plan view of a modified arrangement of the box carrier; and

F 1g. 5, a side elevation of the same.

ySimilar numerals refer to similar parts throughout the drawings.

The carrier A or A may Ainclude'two or more co1l boxes 6 or 6 connected together by a suitable web or frame plate 8 Aor 8; and the side walls 9 or 9 of the boxes may open on the rear for receiving a trunnion bar or splndle 11 or 11 located in the axis of the bundle.

'be' provided with. journal bearings 10 or 10 The carrier is preferably mounted in a pit'V B or B with the-normal bottom 1 2 or 12` in the' plane. of the factory floor; .and a coverplate 13 or 13 may be secured to the carrier as in Figs. 1 and 2 or to the floor as in Figs. 4 and 5 to close the opening of the pit; and in either case the cover plate forms a platform upon which a coil can -be rolled for entering it into one of the boxes.

The bottom of each box may be formed as a hopper vwith an opening therein for freely receiving the coil when its-.trunnion bar ismounted in the bearings; and the side walls of the boxes are preferably in. elined upwardand rearward from the bearings, so as to form skids upon which the trunmons may bear and may be yguided into the bearings when a Acoil is rolled into the box from the factory'loor through the rear open end of the-box.

A's shown in Figures 1 andZ, the forward end of the carrier is provided with flanged wheels 14 riding on an arcuate track l5 and the rear end of the carrier is provided with a radial'beam lrpivoted to a pintle. post 17 at the center of the arcuate rail, 4so that the carrier may ride to and fro upon the rail by turning on the p intle post.

-r as shown in'Figures 4l and 5 the carrier may be provided at front and rear with parallel pairs of4 wheels 14 riding lon a track formed by straight rails 15; upon which the carrier may ride fro.

A'cylinder 18 may be mounted for turning on-a pivotal post 19 with a piston rod laterallly to and i 2O pivotally connected to one side of the carrier for moving the same to and fro by compressed a1r, steam or the like in Well vknown manner.

boxes, While another coil 21 is being unstri Wound in a laterally adjacent box for rolling through a mill C, as shown in Fig. l; and the yend 21 of the one coil can be cut or otherwise made ready While the other coil is being processed.

Furthermore, when a series of strips are wound on one coil, the carrier can be moved laterally when one strip is unwound for preparing the next strip; and at the same time another coil in another box is brought into position for unvvinding and rolling a therefrom. e claim:
