. #Vif/WWK(J GAML tv rgfwgff Mmm UNITED STATES PATENT Cinrro'Eo JAMES OLIVER, OF SOUTH BEND, INDIANA.
`IMPROVEMENT IN CHILLS FOR CASTING MOLD-BOARDS.
Specification forming part of Letters Patent No. 150,882, dated May l2, 1874; application filed February 26, 1874.
To all whom it may concern:
Be it known that I, J AMES OLIVER, of' South Bend, in the county of' St. Joseph and State of Indiana, have invented certain new and use-y ful Improvements in Device for Heating Ohills for Casting Mold-Boards; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.
rlhe nature of' my invention consists in a device for heating chills to be used in casting mold-boards by steam, as will be hereinafter more fully set forth.
In order to enable others skilled in the art to which my invention appertains to use the same, I will now proceed to describe an apparatus whereby my process maybe carried out, referring to the annexed drawing, in which the figure is a longitudinal. section of' a device e1n-l bodyin g my invention.
A represents the ordinary ehll-pan as used in the hot-water device. On the top of this pan I bolt a cast-iron cover, B, packed with rubber or other suitable material to make the joint steam tight. Through the cast-iron cover B, at any desired point, is inserted a nipple, C, iliade of iron tubing, three inches long, more or less. Steam is brought from an ordinary steam-boiler to the chill D by means of steampipe E, laid under ground or overhead. From this main steam-supply pipe I bring a branch pipe, G, provided with a shut-oft' valve, H, to within three feet, more or less, of the chill to .be heated, and connect this branch pipe with the nipple O in the pan-cover by means of a rubber tube, I, which allows the pans A to be placed in any convenient position in relation to the steam-pipe E, owing to the iiexibility of the tube I.
Previous to connecting the chill with the branchvpipe the iiask J is molded up in the usual manner, and a few minutes prior to pour ing in the melted iron steam is let into the chill-pan by opening the shut-off' valve. Steam then enters the chill-pau, a portion of' which is condensed by coming in contact with the cold iron. As the chill becomes heated the condensation of steam lesseiis, until, in a few minutes, the chill-pan is about half filled with boiling Water and the remaining portion is filled with live steam.
By this means the chili is heated much hotter than is possible with the use of hot water applied in the usual manner; the sand is kept dry, as no sloppin or boiling over occurs, and much time and labor are saved over the hotwater process. The foundry is not filled with steam-vapor as when hot water is used.
Any number of' these flasks and pans may be set in a row and heated by means of'bra'nches from the pipe E.
I ain aware that chills have been before heated by steam, and I do not, broadly, claim such device; but
Having thus f'ully described my invention, what I elaiin as new, and desire to secure by Letters Patent, is
The chillpans A, provided with metal covers B, having nipples C, in combination with flexible tubes I, branch pipes G, with valves II, and the steam-pipe E, substantially as and for the purpose specified.
In testimony that I claim the foregoing as my own I aftix my signature in presence of two witnesses.
JAMES OLIVER.
