ANNEALING-BOX.

Specification of Letters Patent.,

Patented Jan. 26, 1909.

Application led .Tune 13, 1908. Serial No. 438,320.

To all whom it may concern.'

Be it known that I, FRANK CORDES, of Pittsburg, Allegheny county, Pennsylvania, have invented a new and useful Im rovement in Annealing-Boxes, of which tllie 'following is a full, clear, and exact description, reference being had to the accom anying -drawin s formln art of this s eci cation,

g P P showing another modication.

My lnvention has relation to annealing boxes, and is designed to provide a novel con,- struction of box adapted to withstand the severe heat to which it is subjected in service, and which by reason of its peculiar construction as hereinafter described, will be more durable in service than the boxes heretofore used.

To this end my invention comprises a box which is cast in a single, integral piece, prcferably of steel, and which has its top arranged in the form of a series of arched domes of 4such form as to be self-supporting.

A further feature of the invention consists in corrugating those portions of the sides of the box which are most likely to give away in service.V

Referring first to the form of box shown in Figs. 1, 2 and 3, the numeral 2 designates the body of the box, which is cast in a single, integral piece, consisting of side and end portions and having a closed, integral top composed of a series of domes 3. These domes are in the nature of groined arches, being arched in both directions as shown, thus forming a dome which is self su orting against any tendency to collapse. he top may be further strengthened by means of the exterior ribs 4, which act as inverted trusses. These ribs are placed between adjacent arches, and extend transverse] of the box With lateral branches 5, which -)ein the adjacent exterior walls of the arches.

6 designates a separate base or support for the box. i l

In the form of my invention shown in Figs. 4, 5 and 6, the to of the box consists of a plurality of simp e transverse arches. The central portions of the side walls of the box are also corrugated as indicated at 7. l

This corrugation gives additional strength to the sides oi the box, and is applied to the central portions, which are the portions which are most likely to give away in service. Fig. 7 shows a plan view ofthe box in which the sides are corrugated and the top is formed by groined arches or domes similar to those shown in. Figs. 1 and 2. While I prefer to ein loy these corrugated sides in connection wit the domed arrangement of` the top as be `applied with shown, yet this feature mayr ox having a difadvantage to any form of ferent design for its top.

While I have shown the boxes, as havin three domes or arches, I do not limit mysell thereto, as the top of thc box may have only two of the deines or arches, or more than three.

Iolaim:

1. An annealing box formed as an interal casting, and havin its top portion ormed into a plurality o groined'arches or domes; substantially as described.

2. A cast steel annealing box having an integral top formed by a plurality of domes, and having exterior supporting ribs or trusses intermediate the domes; substam tially as described.

3. A cast steel annealing box, having an integral top formed by a plurality oi domes, and exterior strengthenin ribs or trusses eX- tending transversely of tie box and intermediate the domes, said ribs or trusses'having longitudinal branches joiningr adjacent domi-l".` substantially as describe 4. An' integral cast metal annealing box\ having its top formed by a plurality of domes, substantially as described.

5. An integral cast metal annealing box having its top formed by a plurality of domes and having thc central portions of its sides formed with vertical corrugations, substantially as described.

6. A cast steel annealing box having the central portions of its sides vertically corrugated and its top formed by a plurality of groincd arches; substantially as i ascribed.

7. I cast metal annealing box having an integral to formed by a plurality of groincd arches or emes and having portions of its sides formed with ivertical corrugations, sub- In testimony whereof, I have hereunto set stantially as descibed. l b my hand.

8. A cast meta annee ing 0X havin en A integral top formed b a plurality of arces, BRANK CORDES' 5 and exterlor strengt ening ribs extending Witnesses:

transversely of the top intermediate adjacent GEO. B. BLEMING,

arches; substantially as described. GEO. H. PARMELEE.
