CHRISTIAN II. BRADY, OF MOUNT JOY, PENNSYLVANIA.
IMPROVEMENT IN IVIOLDS FOR CASTING PLOWSI-IARES.
Siecifieation foi-mimY )art of Letters Patent No. 35,all, dated Julvl 1862.
i el i To e/,ZZ whom t may concern.-
Be it known that I, GHRIsTIAN H. BRADY, of Mount Joy, in the county of Lancaster and State of Pennsylvania, have invented a new and Improved Flask and Mode of Casting and Chilling Plow-Irons in a Vertical Position; 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 of reierencemarked thereon.
Figure lis a perspective view of the flask with the pattern c within ready for molding. Fig. 2 represents the two faces of the pattern or moldboard used in this illustration. Fig. 3 is the chill-drag or nowcl forming the side B of the flask, Fig. l. Fig. 4L is the cope, (marked A) shown detached, all madeofcastiron.
To enable others skilled in the art of casting to use my invention, I will more fully eX plain the features I deem new and peculiar in the mode and flask employed.
My chill-drag or nowel B, Fig. 3, consists of a smooth casting having the face curved and shaped for the reception of the pattern of the mold-board to be cast. This drag has a broad flanged edge, F, with three snugs or ears, F2, which are perforated to receive the pins on the ears E of the cope A. There is also a box with beveled sides K, for molding the head H of C, l and 2. This box has a series of perforations in its bottom, and forms one-half of the runner M. There are also perforations G inside the flange F for the escape of gases generated while casting or lling in. This drag has also lugs L L L on its face, in order to form the holes P P P in the pattern, or, rather, castings taken therefrom. The cope A, Fig.
4t, with its lugs E', handles R, and curved cross-pieces l, 2, and 3, is also cast and corresponds in shape and cnrvings, so as to adapt it at all points to the drag and patternvhich unite and lock, forming the flask, Fig. l.
Sand is put in the box K, and the pattern is laid on the smooth face of the cast nowel, the cope put in place and well packed with sand in the ordinary way. V'Vhen properly molded, the pattern is removed and the flask secured in vertical position. The usual precaution may be employed to prevent the mold from giving way while casting, by the application oi' a i'lat board or plate against the cope, the beveled sides of which are deemed a suliicient protection, however. The metal is poured in through the runner M, formed on the top of the flask by the union of the nowel and cope B A. The smoothness and hardness of plows are highly important, and to gain this object, so much needed and partially attained by chilling mold-boards east in the ordinary wooden flasks inv a horizontal position, they are by this improved ilask chilled while cast in a vertical position, thercby making the most perfeet castings, of apolish and hardness so vastly superior to any cast in the ordinary way as to constitute the device employed as novel as the result, which latter is of the greatest utility and deemed a highly important improvement. Thus I admit that I am aware that chilling plow-irons is not new in the ordinary horizontal position.
I am also aware that cylinders, and perhaps other castings, have been east in a verti cal position; nor do I claim the mere chilling and vertical casting separately considered.
NVh-at I claim as my invention, and desire to secure by Letters Patent, is-
1. The combination of the flask formed by the chill drag or nowel B and cope C, arranged substantially in the manner set for-th.
2. Casting and chilling plow-irons in a vertical position by means of such a ilask.
CHRIST. H. BRADY.
