2 SHEETSSHEET 2- GEORGE 'r. BARB, or YOUNGSTOWN, 1110.-
'PRESSED conrwearnn SHEET-METAL ANNEALING-BOX.
To all whom it mail concern: v
Be it-known that I, GEORGE. P. B RD,-a
' citizen of the United States, residing at Corrugated Sheet-Metal Annealing-Boxes, of which the following is a specification',ref-
Youngstown, in the county of Mahoning and State of Ohio, have invented certain new and useful Improvements in Pressed erence being had therein to the accompanymg drawing. his invention relates to improvements in pressed corrugated sheet metal annealing boxes, and the primary object of the invention is to construct a practical pressed, corrugated sheet metal annealing box whereby I a cheap structure is produced.
The specific object of the invention is to construct thebox ofa body portion composed of two corrugated end portions and the main corrugated body portion so shaped that the edges 6f the ends and main body portion fit together? to be welded, and the lower ends of the main body portion and endportions so shaped that they provide downwardly extending welding surfaces substantially flush with each other to receive an L- shaped strengthening and supporting base rim welded to the said lower welding portions of the body and ends, making a simple, cheap and effective structure.
Other specific objects of the invention will appear from the following description.
In the accompanying drawings ,Figure 1 is a side elevation of my imroyed corrugated sheet metal annealing Fig. 2 is a top plan view of Fig. 1. Fig. 3 is an end elevation of the box. Fig. 4 is a detached end elevation of one of the box ends.
Fig. 5 is a sectional view on the line 55 ofF1g.3. a
My improved corrugated sheet metal anneallng box is prefera ly composed of commercial open hearth steel audit is made up of four parts, viz., a main body portion 1;
two-end portions 2 and an L-shaped com-' bined strengthening and base portion rim 3. The main body portion, as here shown, is
-made up of a single sheet of-metal, which is bent into approximatelyan inverted U-shape with transverse corrugations 4. .The ends of the corrugations 4: begin at the points 5, above the lower edge of the'main body portion, leaving a straight downwardly extending lower welding edge/6. These corruga- Specification of Letters, Patent.
. are in the same horizontal plane.

tions are uniform inwidth across the top of the body portion 1, as shown at 7, and gradually narrow or taper at the sides of the box to their lower ends 5, as shown in Fig. 1.-
" The ends 2 of the box are made .up of corrugated plates, the corrugations of theends made of different lengths, the longestbeing in the center of the plate and the cor- ,rugations at'the side of the center being made substantially shorter at their upper ends, thus bringing their upper ends in different horizontal planes at the side of the center corrugation, whilev their lower ends These ends 2, have their lower. ends 8 straight and in substantially the original plane of the sheet from vwhich the ends are pressedor stamped, which brings their ends 8 substantially flush with the straight lower ends 6 of the main body portion 1, while the sides and curved tops of the end pieces 2 are bent inward beyond the plane of their lower ends 8, as shown at 9, to provide lapping welding engaging surfaces 10 between the sides andtop' 9 and the bend of the end cor- 'rugation'of the main body 1.
By reason of this specific construction, the
lower endsof the "main body portion and its ends2 form a welding surface 11, which is substantially flush for the purpose of receiving an outside L-shaped combined strengthening'angle iron and rim12; This angle iron 12 is preferably composed of a single piece bent into a contour corresponding to and fitting outside of the end por- .tions 8 and 6 of the main body portion 1 and its ends 2, and the ends of the bent an'gle iron- 12 are welded together at the point 13.
The corrugations 14 of the end pieces 2 have their lower ends 15 above the straight ends 8, and substantially in the same horizontal plane, whereas theupper ends of the corrugations at each side of the center one are in difi'erent horizontal planes, thus con-- stituting corrugations of various lengths.
My construction of box is composed of few parts and each part is of a shape which is practical to stamp or press and shape to assemble, and when assembled, produce an efi'ective annealing box at a relative economical expenditure, while at the same time it produces a box which- Will eflectively stand up under the intense heat to whlch such boxes are subjected. It is understood, of course, by those skilled in the art that all annealing. boxes are necessarily compara tively short lived, because of the intense heat surrounding them when in use, irrespective of the material of which it is constructed. In view of the unavoidable short life of such boxes, a box which is of apractical cheap Construction is highly desirable, and. boxes of the construction here shown and described will be found to be substantially long lived to make it cheap, as compared with other types of annealing boxes and their life under practical use.
From the foregoing description, it will be noted that the main body portion and the end pieces have their lower edgesstraight, or, in other words, in the same or substantially thesame straight plane as the plates from which they are shaped, and by reason of this construction the straight surface 11 is formed to receive the inner straightwalled L-shaped angle iron rim 12, as before described. Access to the inside of the box is had through its open bottom.
The corrugations in the main body portion 1 and ends 2 are for the purpose of providing for the expansion and contraction of the box, due to it being intensely heated and y then cooled and vice versa, and also provide strengthening ribs, so to speak, for support-' ing the top of the box against undue caving in or warping.
Having thus described my invention,
what I claim and desire to secure by Letters 2. An improved annealing box, composed of corrugated sheet metal, an inverted U- shaped main body-portion having continuous transverse corrugations with their ends end pieces curved inward to fit against the curved ends of the body portion and welded thereto.
3. An improved corrugated sheet metal annealing box, comprising a U-shaped body I portion having transverse corrugations ending above. its lower edge to form a straight lower edge, end pieces having straight lower edges corresponding to the lower edge of the body portion and corrugations, the sides and tops of the end pieces curved inward beyond their straight lower ends and welded to the curved ends of the main body portion, and an L-shaped base bar fitting the outsides of the straight portions of the ends andbody and welded theretof 4. An improved corrugated sheet metal annealing box, comprising an inverted U- shaped body portion having transverse corrugations ending above its lower edge to form a straight lower welding portion,
separate end pieces having a straight lower edge corresponding to the straight lower edge of the body portion and also having vertical corrugations, the adjacent edges of the end pieces and body portion having correspondingly formed overlapping welded portions, and a strengthening base iron surrounding and welded to the straight lower edges of the bed portion and end ieces.
In testimony w ereof I hereunto a 1x my signature.
