IMPROVEMENT IN CASTING CHILLE D ROL LS.
specification forming part of Letters Patent No. 1 39,798, dated J mm 10, 1873 application filed January 21, 1873.
Improvement in (lasting Chilled Rolls, of
which the following is a specification The object of my invention is to prevent the breaking of the necks of chilled rolls during the process of casting the same, and to readily adjust the mold so as to cast rolls of difl'erent lengths. This object I attain by a sleeve, D, lined with sand or loam b, and adapted to' the interior of the chill A, substantially as shown in the vertical section, Fig. 1, so that it can be adjusted vertically in the chill, and can yield and accommodate itself to the shrinkage of themetal poured into the mold.
A is the upper .portion of the chill, in which the body of the roll is cast, and on the top of this chill is placed a box, B. D is a metal sleeve or cylinder, shown'detached in Fig. 2, the upper portion of which is contained in the box B, and the 10We1 portion in the chill, in which it can slide freely. The. inside of this sleeve is lined with sand, or its equivalent,
molded to the desired shape of the neck b of the roll.
When this sand lining has been properly dried it is placed with the sleeve D in the chill in the position which the length of the roll to be cast requires, the upper portion of the sleeve being contained within a body of runners into the lower end of the mold, rises 7 roll, thereby preventing the separation of the same at the neck,which is liable to occur when the upper neck adheres to a fixed portion of the mold.
I prefer to perforate the sleeve, and, also, the box B with small holes, as shown, so as to permit the free escape. of gases generated by.
the molten metal, these vents insuring the soundness of the neck of the roll.
One of the most important advantages of my invention is the facility which the sleeve afl'o'rds for making rolls of different lengths, the length of the roll being determined by the simple adjustment of the sleeve in the chill.
I claim as my invention- 1. The sand-lined sleeve D, applied to the mold so as to be movable and adjustable there- I in, as set forth. 2. The sand-lined sleeve, suspended in the chill by rods m m, or their equivalent, as spec- 3. The combination. of the perforated sleeve D with the perforated box B and its prepared lining.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
