' 1:: Claims. (01. 263-47) This invention relates to new. and useful improvements in apparatus to be used, in the heat treating of wire and has particular relationto a combination pot and loading stand for use when annealing wire.

An object of the invention is to provide a combination pot and loading. stand so constructed that itis not. necessaryto invert the stand to unload it. v r a A further object is to: provide an apparatus as stated and which does not require that the hood or cover do other than exclude gasestand since it is only required to. support. its own weight may be madewith a thin. wall to reduce .its bulk and weight and to have it more readilytransmit heat. N a 1.

Another object is to providean apparatus hav.- ing the characteristics indicated and which will have long useful life, v 1 v Other objects and advantages willbecome ap-. parent from a consideration of gthe. following detailed description taken. in connection with the accompanying drawing,.whe rein a satisfactory embodiment of the invention is shown. However, it will be understood that the invention is not limitedto. the details disclosed outincludes-yall such variations and modifications as fall within the spirit of the invention, and the scope of the appended claims.

In thedrawinga.

Fig. 2 is a view, partly in elevation and partly in section showing the loading stand alone; 7

Fig. 4-. is a sectional view takensubstantially along the line 4-4 of Fig. 2i, j r

Referring in detail to the drawing the im: proved combination pot and loading stand as here shown includes a relatively heavy base l0 constructed to support the weight of the wire bundles with which the stand to be loaded and such base is provided centrally with a thickened or raised portion I l providing a shoulder [2 the upper corner [3 of (which is preferably rounded as shown in Fig. 2 so as to prevent wire catching thereon. Rigid with the portion II and extending upwardl therefrom is a, tubular piece or collar [4 shown as fastened to the base in'any suitable manner although it will later become apparent that this coil'ar l4 might beintegral withthebase. l I

Through its thickened portionthe base is provided.- with a key shaped opening l5 and ad-- jacent. its outer edge it is provided in its upper surfacewith a groove IS the purpose of which will later be described. In order to reduce the weight of the base its under side may be ribbed as suggested at H, the said ribs being arranged to engage a supporting surface to prevent crushing of the base under the load and also pro viding a structure wherein the base is of less weight due to the fact that it is not solid but has spaces between its ribs.

A centering sleeve l8 (the outside diameter of which. should beapproximately the same as the diameter of the hole through a bundle of wire) is provided. and this sleeve is mounted on the base by. telescoping the lower end of the sleeve over the collar l4, whereby the sleeve is properly locatedand is prevented from moving or tilting out of its proper position. Whenbundles of wire are-tube loaded onto the stand the sleeve I8 is disposed over the collar I4 as describedand a lifting rod l9 extends through the sleeve and through the opening l5 in the base and the bundles 26 are disposed about the sleeve as shown. At its upper end the lifting rod is provided with an eye 20 for the passage of a book of a crane, and at its lower end the rod is provided with a lug 2| shaped to pass through the opening IS in the base when properly aligned therewith. Also, on the rod I 9 and within the sleeve. I8 are centering or locating discs 22 and 23..

' Within and secured to the sleeve (8 above the upper locating disc 22 are a plurality of lugs 24 which lugs project into the sleeve to such an extent as to prevent the disc 22 being drawn upwardly through the sleeve. When the lifting rod l 9 is within the sleeve as shown in the drawing, the lug 2! at the lower end of said rod is disposed at the under side of the thickened or raised portion of the base It! in position out of 'alignment with the opening I 5. This is best shown by the dotted lines in Fig. 4:.- Therefore,

about the stand or on the stand in a manner to enclo e bundles of wire 28. This hood as shown is" of relatively thin walled heat resisting steel and has no part in supporting the load of wire bundles being heat treated. When the hood is in place the lower edge of its side walls is within the groove I 6 of the base and sand or the like 36 may be placed in the groove so as to form a has an upper end wall 26 provided with a central opening and the portion of the hood about said opening is bent or flared downwardly as shown at 21 and. rests on the upper end of the sleeve I8 partially entering. the sleeve and therewith forming a reasonable seal to exclude gases from the bundles of wire 28. At opposite sides the hood .is provided with lifting lugs 29 by means of which the hood may be lifted'onto and off the base.

In the use of the present apparatus when bundles of wire are to be heat treated the sleeve 18 is. positioned over the collar [4 with the lifting rod 19 positioned as shown; The bundles of -i'st-ry with the opening H5 in the base, the hook of a crane may be passed through the eye of such rod and the entire apparatus lifted into a furnace. I

After the required heating the crane may again be connected with the eye 20 and the entire apparatus lifted out of the furnace and deposited on the floor. After the required cooling a hand bar is passed through the eye 20 and the rod 19 is turned to-bring itslug 2|v into registry with theopening l5 in the base. This'is preferably done after the hood 25 has been lifted off and then, by a crane or other means engaging in the eye 20 of the rod IS the latter is lifted up-out of the base and through the pile ofbuhdles on-the base. As the rod is picked up the top centering disc 22 thereof will engage thelugs 24 on the inner surface of the sleeve l8 and the sleeve will be lifted up with the'rod and carried out of the stack of bundles on the base. Thereafter, there'being no center means 'or sleeve l8 through theubundles of wirethey may simplybe pushed oif the base. a 1 In addition to the hood 25 being of heat resisting steel whereby it will not warp or get out of shape itwill also be appreciated that this hood is not requiredto support any of the weight of the bundles on the stand and so does not lose its proper shape and has long life. Rod [9 is also of special heat resisting steel whereby-lit will not be stretched out of shape particularly during the lifting of the apparatus out of a furnace, at which time therod is hot.

When the bundles of wire are piledwithin a receptacle the latter must beheavy and strong to support the weight imposed .on it and resists the transmission of heat to its contents when in theifurnace and also has a tendency to elongate and warp. ,In addition with such a pot it is necessary to handle it with a crane in order topick it up and dump it at the end of a heat treating operation. Since the sleeve [8 and rodl9rof the present device may be lifted vertically out through the bundles on the base ID at the end {of a heat treating operation itis not necessary to pick the stand up by a crane and dump it. ;The bundles may simply be pushed off the stand.
