UNITED STATES PATENT OFFICE.
JOHN BARROIV, OF COLUMBIANA, OHIO.
ANNEALlNG-BOX.
SPECIFICATION forming part of Letters Patent No. 579,946, dated April 6, 1897.
Application filed October 31, 1896. Serial No. 610,689. (No modell) To @ZZ wir/07u it nu@ concern:
Be it known that I, JOHN BARROW, a native of England, residing at Columbiana, in the county of Columbiana and State of Ohio, have invented certain new and useful Improvements in Annealing-Boxes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the saine, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.
This invention relates to improvements in annealing-boxes used in the manufacture of tin plates. In the manufacture of such boxes it is customary to' make them of sheet or wrought iron in two or more parts, the joints being welded. It has also been proposed to make annealing-boxes with corrugations or flutes to allow for the expansion and contraction of the metal.
As heretofore practiced, the annealingboxes when made of wrought metal were constructed of several pieces, and when so constructed each joint was an element of weakness, as it was essential that such boxes be made absolutely tight in order that the best results might be obtained.
In carrying out my invention I make an annealing-box from a single blank presenting a central portion forming the top and extensions which form the sides and ends, the parts being corrugated, but such corrugations do not in any manner affect the joints, which have more or less metal than the other parts of the box.
In the accompanying drawings, forming part of this specification, Figure l is a plan view of a blank from which my improved annealing-box is made. Fig. 2 is a view showing the corrugations in the blank. Fig. 3 is a bottom View showing the box formed ready for welding at the vertical corners thereof.
A designates a blank made up from a sin gle sheet of metal to present a central portion forming the top of the box and extensions a a and a a, which form the sides and ends, respectively. At the junction of the extensions forming the sides and ends of the box the blank is constructed to provide a curved portion b instead of an angle for the purpose hereinafter set forth. The side edges of the extensions a are beveled, as indicated in the drawings, and the portion which forms the top of the box is stamped or corrugated.
In making a box from the blank hereinbefore described the extensions a a and a a' are bent to be at substantially right angles with the central portion and the portions b will form rounded instead of angular corners. The edges of the extensions or sides and ends of the box are brought together so that they will lap, the beveled edges of the ends a' bearing against the inner surfaces of the sides a, thus presenting a smooth interior for the box. The corners or overlapping edges of the sides and ends are then welded together, and an absolutely tight annealing-box is formed with a preponderance of metal at the joints, which insures the requisite amount of strength at these points and presents no joints at the upper edges, which are usually the vweakest places in boxes for this purpose and receive the greatest strain.
My improved annealing-box is used with the ordinary stand and in the usual manner.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
l. A blank for use in the manufacture of annealing-boxes made of a single piece presenting a central portion'forming the top of the box and extensions a a and a a forming the sides and ends thereof, the blank at the junction of said extensions presenting curved portions b, substantially as shown and for the purpose set forth.
2. As an improved article of manufacture, an annealing-box made up of a single piece of sheet metal presenting a central portion and extensions a a and a ce with curved ortions l) at the junction of said extensions, the parts being stamped or corrugated, substantially as shown and described.
In testimony whereof I affix my signature in presence of two witnesses.
JOHN BARROW.
