ANNEALING SPIDER Y Filed Sept. 23, 1955 ATTORNEYS ANNEALING SPIDER John P. King, North Haven, Conn., assignor to The Alfred B. King Company, North Haven, Conn., a corporation of Connecticut Appiication September 23, 1955, Serial No. 536,079

3 Claims. (Cl. 263-47) This invention relates to an annealing spider or arbor for supporting coils of wire or rod during annealing or similar operations or in transporting the coils from one place to another.

In a device for this purpose it is desirable to provide an arbor or spider which will be sulficiently strong for supporting a number of coils of rod or wire so that they may be handled expeditiously by a hoist or like mechanism and which will be of such structure that it will withstand the rather severe usage to which such a device may be put and also stand the heat to which the coils may be subjected without warping or losing its shape. Also it is desirable to so construct the spider that there will be a free flow of hot gases around the material supported upon it so that the coils will be evenly and efficiently heated. At the same time the coils should be so supported that they will be maintained in circular form and not be distorted from their round shape.

It is also contemplated by the present invention to provide a relatively short stacking spider which is so constructed that one may be supported on top of another with a coupling pipe between the two spiders to hold them in alignment.

As illustrated, the spider or arbor comprises a bottom plate having a loading stem or core rising therefrom, this core being formed of a plurality of formed metal sections of substantially V-shaped form, the adjacent edges of these sections being joined together to form a hollow ribbed cylinder with the vertices of the sections extending outwardly from the seams between the sections. This in effect provides a reinforced core of hollow generally cylindrical form by providing a point or line contact with the coils when placed upon the core. Such a construction forms a veryrigid core which will withstand the stresses to which it is necessarily subjected and at the same time provides a minimum area of contact between the core and the coils, keeping the coils round and at the same time preventing sticking of the coils to the core.

One object of the invention is to provide an annealing arbor or spider of improved construction and design.

A further object of the invention is to provide an annealing arbor or spider which will be so constructed as to maintain at a minimum the metal-to-metal contact between the spider and the coils and at the same time provide a rigid construction which will not be likely to be warped or distorted when in use.

Still another object of the invention is to provide an annealing arbor or spider of the character described which will have provision for free circulation of the hot gases through the various elements of the spider itself and also around the coils so that the latter may be evenly and efficiently heated.

Still another object of the invention is to provide an arbor or spider constructed of plate-like sections of substantially V-shaped form in cross section and so join the sections together that they will be properly braced States Patent Patented May 13, 1958 Fig. 1 is a side elevational view of an annealing arbor or spider embodying my invention;

Fig. 2 is a top plan view of the device;

Fig. 3 is an enlarged sectional view on line 3-3 of Fig. 1;

Fig. 4 is a sectional view on line,4-4 of Fig. 3; and

Fig. 5 is a view partly in section and partly in elevation of the coupling member employed for joining one spider to another when one is superposed upon the other.

To illustrate one embodiment of my invention I have shown in the drawing an annealing arbor or spider comprising a base plate 10 which in this instance is of substantially circular form, this plate being secured to the lower end of a core designated generally by the numeral 11, this core being hollow and of generally cylindrical form and of a construction to be described hereinafter. the base plate 10 is provided with an opening 12 (Fig. 3), this opening permitting the hot gases to pass upwardly through the hollow interior of the core 11 and the diameter of the opening being such that it is substantially circumscribed within the sections of the core.

As shown more especially in Fig. 4, the core or stem 11 is formed of a plurality of substantially V-shaped sections 13, these sections being constructed of metal plate formed as shown so that they are substantially of V shape in cross section. The vertices or ridges 14 of these members are directed outwardly and at their inner edges one section abuts the inner edge of an adjacent section, as shown at 15, and these edges are welded together, thus forming a reinforced ribbed or rigid generally cylindrical structure of hollow form.

It may be noted that with the vertices or ribs of the sections projecting outwardly, the coils when placed upon the arbor will abut these ridges and only contact the core at these points. There will, therefore, be a minimum of contact between the coils and the exterior surface of the core although the coils will be maintained in their round shape as a sufficient number of sections will be provided for this purpose, eight as shown in the drawings.

This core formed as explained above is placed upon the base plate 10 and secured thereto by welding or the like. As shown in the top plan view of Fig. 2, the base plate is also provided with a plurality of through openings 16 to permit circulation of gases therethrough and around the coils, all of these openingsbeing disposed between adjacent sections 13. Thus the hot gases may rise through the openings 16 on the outside of the core as well as through the opening 12 upon the inside. It will also be understood that the base. plate 10 is of larger diameter than the outside diameter of the core so that the coils of wire indicated at 17 in Fig. 1 will rest upon this projecting portion of the base plate.

A cover plate 18 may be provided upon the core,'this plate being of substantially the same shape and size as the shape and size of the cross section of the core itself so that the sections will be braced at the top and held rigidly in place, this cover plate also being welded to the sections of the core. This plate'is provided with an opening 19 to permit exit of the (gases passing through the center of the core.

3 It is noted that the diameter of the opening 19 is less than the distance across the interior or" the core between opposite edges thereof so that the portion of the cover plate around the opening 19 will overhang the interior of the core to provide for the lifting of the arbor by crane books or the like inserted through the opening.

Secured within the core, as shown more especially in Figs. 3 and 4, is a receptacle or socket member comprising ahollow cylinder body 20 and

end flanges

21 and 22, the periphery of these flanges being secured by welding or the like to the inner edges 15 of the sections 13 so as to secure this member in place and also serve to some extent to brace the sections 13.

A coupling member,-shown in Fig. 5, consists of a pipe or stem 23 to which .is-Vsecured an-enlarged body portion 24. These members are .hollow and the top of the body portion is provided with van opening 25so there will be free circulation of gases ,upwardly through the coupling member. As shown in dotted lines in Fig. 3, the coupling member may be .placed uponthe-cover plate 18 with the I stem 23 extending-downwardly through the opening 19 and fitting snugly within the body portion 2% of the receptacle while the body member 24 rests upon the plate 18.

When it is desired tostack a second arbor upon the first, the coupling member is put into place,-as shown in Fig. 3, and the second arbor lowered upon the first. The body portion 240i the coupling member which, as shown, is tapered upwardly and inwardly will be received in the opening 12 in the .base plateof the upper arbor and will hold the two in alignment. It will be noted that when two or more of the arbors are stacked one upon the other in this manner, a continuousopening is provided therethrough by reason of the opening through the coupling members and the hollow interiors of the cores 11.

By the above construction there is provided an arbor which may be economically made and which at the sam time will be of rigid and strong construction to withstand the stresses to whichit may be subjected. At the same timea minimum area-of contact is provided between the arbor and the coils .17 due to the fact that thereis substantially a .linecontact between the vertices 14 and the coils andat the same time the vertices will contact the coils to maintain-their round shape. Also thereis provided a freecirculationof hot gases through the interior of the core within the hollow sections 13 and also around the coils on theoutside of.the core by reason of the openings 16.

While I have shown and described one embodiment of my invention, it will he understood that it is not to be limited'to all of the details shown, but is capable of modification and variation within the spiritof the invention and within the scope of the claims.
