1 Claim. (Cl. 26347) This invention relates to a spool or coil holder, and more particularly to a device for supporting a plurality of spools or coils of wire for transportation from one place to another or for other purposes such as during annealing operations, for example.

In the handling of wire it is common to wind the wire upon spools or wind it in coils and handle the wire in this manner. When transporting spools or coils from place to place, it is desirable to have some supporting device which will hold the spools or coils in relatively fixed position so that one spool will not come in contact with and damage the wire upon an adjacent spool.

Moreover, it is sometimes necessary to anneal wire, and it must for this purpose be transported to the annealing oven and removed therefrom. The holder of the present invention is designed for such purpose as it will so support the spools that there will be a free flow of hot gases around the wire in addition to the fact that the spools are supported in spaced relation so that the wire on one will be maintained out of contact with that on another.

In addition the holders are so constructed that they may be stacked one upon the other, and the hollow pipes upon which the spools are placed will in such case combine to form a continuous flue so that the annealing gases will be carried through these pipes when the holders are stacked one upon another.

One object of the present invention is to provide a new and improved spool or coil holder of relatively simple construction and which is economical to manufacture.

A still further object of the invention is the provision of a spool or coil holder which will be provided with all of the essential parts necessary for a device of this character, but in which unessential parts have been omitted so as to provide a structure of most simple form and of relatively light weight, and one which is economical to manufacture.

Still another object of the invention is to provide a spool or coil holder of the character described which is so designed that one may be stacked or superposed upon another for use in an annealing oven, for example, and so designed that provision is made for the free passage of annealing gases around the coils supported upon the stacked holders.

To these and other ends the invention consists in the novel features and combinations of parts to be hereinafter described and claimed.

In the accompanying drawings:

Fig. 1 is a side elevational view of a spool or coil holder embodying my improvements;

Fig. 2 is a top plan view thereof; and

Fig. 3 is a broken sectional view on line 33 of Fig. 2.

To illustrate a preferred embodiment of my invention, I have shown a spool or coil holder comprising a base plate which in this instance is of circular form and serves as the main supporting plate of the device. This plate is normally made of suitable metal and may be of Patented Aug. 20, 1957 any desired dimension as to thickness so as to be able to support the required weight.

This plate is provided with a central opening 11 (Fig. 3), and in this opening is secured a central relatively large tubular member or pipe 12 which serves as the lifting or carrying member by which the holder is transported from place to place. Within the upper end of the tubular member 12 is welded a plate 13 having an opening 14 therein so as to provide an annular member or flange extending inwardly from the wall of the pipe. It will be understood that lifting tongs can, for example, be dropped into the opening 14 and, by engagement with the lower surface of the flange or plate 13, be employed to lift the device so that it may be moved from one place to another. Also it will be noted that the openings 11 and 14 provide for the free passage of annealing gases, for example, through the central tubular member 12 so that the latter in effect forms a flue for such gases.

Also secured in openings in the plate 10 are an inner row of upstanding tubular supporting members 15 and an outer row of such members 16. As shown in Fig. 3, these members are disposed in openings 17 and 18 respectively of the plate 10. These members are left open at their upper and lower ends so as to provide gas flues when used in connection with annealing operations.

The

tubes

15 and 16 are designed to serve as central supporting or holding means for the spools or coils of wire, the latter being shown in dotted lines at 19 on Fig. 2. From this figure it will be noted that while any desired number of

tubes

15 and 16 may be employed, they are preferably so arranged that they will be sufliciently far apart so that the wire of one spool will not engage or foul that on another spool even though there must be some play or looseness between each spool and its supporting tube. That is, some clearance must be left between the outside diameter of the supporting

tubes

15 and 16 and the inner diameter of the spool, so that the latter may be freely received upon the tubular support and, while this clearance will permit some movement of the coils with respect to the support, the coils should be prevented from coming into contact with each other. As shown, the tubular supports are arranged in an inner annular series about the central supporting tube 12 and an outer annular series, the latter containing approximately double the number of supporting tubes as the former. The lower ends of these tubular members are inserted into the openings 17 and 18 and are welded to the plate 10.

Below each of the tubular members 15 and 16 a guide or stacking ring 20 is secured to the base plate 10, these rings being of suflicient size to receive therewithin the upper ends of the

tubular members

15 and 16 of a second holder when one is stacked upon another.

Such a disposition of a plurality of holders is shown in dotted lines in Fig. 3 where the rings 20, shown in full lines, receive the upper ends of the

tubes

15 and 16 of a lower holder while the upper ends of the

tubes

15 and 16, shown in full lines, are received in the rings 20 of an upper holder, the latter being shown in dotted lines. It will be apparent that this nesting of the holders one upon the other will align the

tubular members

15 and 16 as well as the central tubular members 12 so that these members will provide through lines for the passage of the annealing gases.

The plate 10 may also be provided with a plurality of openings 21, these openings being arranged between the rows or series of

tubular members

15 and 16 and are so proportioned that they are substantially tangent to the coils of wire upon the supporting

members

15 and 16, as shown in Fig. 2. These openings also provide for the passage of annealing gases upwardly about the outside of the coils.

the entire device will be lifted by the central tube 12. It

will also prevent warpage of the plate 10 at that point at which warpage might occur due to the fact that this plate is subject to the heat of the annealing oven during annealing operations.

While I have shown and described a preferred embodi ment of my invention, it will be understood that it is not to be limited to all of the details shown, but is capable of modification and variation within the spirit of the invention and within the scope of the claim.

What I claim is:

A spool-holding structure comprising a circular disklike base plate, a plurality of open-ended tubular members, each secured at one end to the plate and projecting upwardly therefrom in substantially parallel spaced relation, one of said members being disposed substantially centrally of the plate to serve as a lift member, and the others of said tubular members being arranged in circular series around said central member and serving as 4 spool-holding members, said plate having openings therethrough below and leading into each of said tubular members, guide rings secured to the lower surface of said plate below said spool-holding members, the openings in said rings being dimensioned to receive the upper ends of the spool-holding members of a second structure when one is superposed upon the other to align and locate the spool-holding members of both structures to provide a continuous flue therethrough, said plate also being provided with additional openings between said spoolholding members, bracing members of triangular form secured at one edge to the lower end of said 'lift member and at another edge to the upper surface of the plate, and said lift member having an inwardly projecting flange at its upper end by which the structure-may be lifted.
