UNITED STATES PATENT QEEIGE.
CHARLES H. ONIONS, OF PITTSBURG, PENNSYLVANIA.
IMPROVEMENT IN ANNEALING-BOXES.
Specification forming part of Letters Patent No. 168,408, dated October 5, 1875 application filed January 13, 1875. v
CASE B.
To all whomt't may concern Beit known that I, CHARLEs H. ONIoNs, of Pittsburg, in the county ot Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Annealing-Boxes; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters ot' reference marked there- My invention relates to an improvement in the construction of the bottom of annealingboxes; and consists in constructing it ofcastiron, with a series ot' wrought-iron rings secured wit-hin the bottom in the process of molding and casting it.
To enable others skilled in the art to make and use my invention, I will proceed to describe more fully its construction and operation.
In the accompanying drawings, which form part of my specitication, Figure l isasectional view ot' my invention, taken onthe line xm ot' Fig. 2. Fig. is a transverse section of the same at line y of Fig. 1.
In the drawings, A represents the bottom ot' the annealing box. B represents the grooved runners, which rest upon balls in the annealing-oven, which are used in connection with said runners for removing the annealing-box from the furnace with ease and facility. C represents wroughtiron rings cast in the end ot' the bottom A, t'or the purpose of attaching a. chain or rod tor withdrawing the annealing-box from the furnace.
The bottom A is constructed in all respects in the usual manner and ot' the ordinary material, (cast-imm) excepting that longitudinally in the bottom, as represented in the accompanying drawings, are two or more wrought-iron rings, which are surrounded by the metal ot' the bottom in the process of casting, which is accomplished by anchoring the rings in the mold, which operation ot' anchoring and casting is well understood by the skillful molder.
The advantage of casting rings in the bottom of the annealing-box, as herein described, consists in imparting strength to the bottom, and compensating for the expansion and contraction ot' it in the heating and cooling of it.
Another advantage derived from 4the use of rings cast in the bottom of the annealingbox, in contradistinction to the use of rods or bars, consists in affording greater facility in breaking the bottom into small pieces for the purpose ot remelting in case the bottomA should crack (which is ot'ten the case) or otherwise be rendered useless.
I am aware that it is an old and common practice to cast rods or bars of iron in castiron articles in the process of molding them, for the purpose ot' imparting strength to the casting. Therefore, I do not claim, broadly, combining wrought-iron with aV casting in the process ot' molding and casting.
I am aware that wrought-iron rods have been placed longitudinally in annealingboxes; but the additional strength thereby obtained is wholly in the direction of the length ot' the box, no addition beingI made to the lateral strength. By the use ot' rings I obtain both lateral and longitudinal strength.
Further, the rods heretofore used are embedded in projecting ribs on the bottom and sides ot' the box, while my r-ings are embedded in the bottom proper. In thet'ormer case the thickness ot' the parts is materially increased, and in consequence, when it is attempted to break up the box for recasting, considerable difficulty is metwith; whereas the rings lessen the thickness of the bottom, both above and below them, so that all the body ol' cast-iron, which is directly above and directly belowthe rings, and throughout their extent, is much thinner than other parts ot' t-he bottom ot' the box, and the bottom breaks readily at points directly above and below the rings under very slight blows.
Having thus described the nature, const-ruction, and operation of `my improvement, what I claim as ot' my invention is- In annealing-boxes, the combination of the wrought-iron rings D D D with the cast bottom A, whereby the longitudinal and lateral strength of the bottom is materiallyincreased and its vertical strength diminished, substantially as and for the purposes hereinbefore set forth.
