Definitions
- l ment consists in casting the pipe-box upon a cast-iron core inadein segments and bound together by iron bands, so that before the metal cools and contracts said core can be taken to pieces and extracted from the box, leaving it to cool gradually Without any danger of breaking and imparting to the interior surface of the box a hardness that will resist the action of the file or chisel.

UNITED 4STATES PATENT OFFICE.
JOHN HUNTINGTON, OF ZANESVIIJLE, OHIO.
IMPROVEMENT IN THE MODE OF MAKING METALLIC CORES FOR CHILLING CAST-IRON PIPE-BOXES FOR THE HUBS OFCARRIAGE-WHEELS, &c.
Specification forming part of Letters Patent No. 3,929, dated February Q4, 1345.
l ment consists in casting the pipe-box upon a cast-iron core inadein segments and bound together by iron bands, so that before the metal cools and contracts said core can be taken to pieces and extracted from the box, leaving it to cool gradually Without any danger of breaking and imparting to the interior surface of the box a hardness that will resist the action of the file or chisel.
In order to cast the core, I prepare a set of patterns in wood of shapes corresponding to those representedin Figures 1, 2, 3, 4, 5, 6, 7, the central piece, 7, being atapered polygon. 1With these patterns I form the impressions in the sand to cast corresponding figures. These being east, I put them `together and bind them with rings,forrning the core, as represented in Fig. 8, R being the rings. A is the tapered polygon. B C D E F G are the segment-patterns. I
With the patterns H I, Figs. l0 and 12, for the hub, I form the drag and cope. I then place the castiron core, Fig. l0, in the drag and put on the cope. I then pourin the melted is cool I drive ont the tapered polyonal center piece, A. I then drive inward toward the center one of the segment-pieces, B. The other pieces, C D E F G, will then fall asunder and must be removed from the interior of the box. The box J is then suffered to cool, and when cool it will be found to possess great accuracy of form, a good finish, and an extraordinary.
degree of hardness, Which will resist friction a great length of time, and of course will have all the depressions and protuberances on its interiori surface corresponding with the depressions and protuberances on the outer surface of the aforesaid metallic core, Fig. 10, necessary for admitting the lubricating Inatter introduced through an aperture, K, in the box, and an internal hook, L, fastened to the axle-tree M and reaching to near the middle of the box for holding or securing the box to the axle-tree without the use of a linchpin, screw, or cap, or any other fastening.
XVII-at I claim as my invention, and which desire to secure by Letters Patent, is-
The mode or manner of casting pipe-boxes for carriage and other Wheels by the use of the segment-core, Fig. l0, constructed and arranged and used in the way described, for chilling or hardening and iinishing the interior surfaces of the boxes.
JOHN HUNTINGTON.
