JOHN C. PARRY, OF PITTSBURG, PENNSYLVANIA.
METHOD OF GIVING ROTARY MOTION TO FLUID IRON IN CASTING ROLLS.
Specification forming part of Leiiers Patent No. 7,383, dated May 2]. 1850.-
To all whont it may concern.-
Be it known that I, JOHN (J. PARRY, of Pittsburg, Pennsylvania, have invented a new and useful Mode of Giving a Rotary Motion to the Metal in Casting Chilled Rollers and other Metallic Rollers and Castings; and I do hereby declare that the following is a fulland exact description thereof, reference being had to the annexed drawings, forming a part of this specification, in whieh--.
Figure 1 is a perspective view of a chilled roller. Fig. 2 isa perspective view of a vertical section through the center of the mold and chill in which the roller is cast, representing one-half hereof, the mold and chill forming an intaglio impression of the roller, and also'representing the fan or paddle and Fig. 3 is lower journal and above the gaten'epresenthig the position of the fan or paddle, corresponding parts in the several figures being represented by the same letters.
A chilled roller (see Fig. 1) is composed of the ccnteror main part of the roll, (marked a,) the upper and lower journals, (marked I) b,) The journals are cast in molds of sand (see Fig. 2) made in the flasks ff. which are clamped or fastened to upper. and lower ends of an iron cylinder, called. a chill, (marked (2.) A long pipe or rjinner, c, communicating with the gate 1, conducts the melted metal into the lower part of the mold, either in the lower journal, 1/, or coupling (1.
The fan or paddle h, Figs. 2 and ll, is made of cast or wrought iron, and is composed of four runes or fans, which a're'placed at right angles to each other at the extremity of an iron rod, '1', which is inserted in the mold and chill through the ppcning in the top,'ealled the sinking head, to the depth of the lower journal, 1/, the end of the rod being kept in its place inthe center of the mold by a slight iron rod, -r, Figs. 2 and 3, with-a. circular ring or hole in its center, the rod 2' being sunk-its own depth in thesand at the junction of .the lower journal, 1;, and eou-pling'c; or it may be placed in the bottom of the lower coupling, 0, sunk to its own depth in the sand, in which case the paddle h must not be lowered; but the rod 23 must be lengthened, so as to enter the ring in the rod r; The upper end of the paddle-rod i rises out of the mold and passes through a frame-work, k k, which is attached to the upper flask, ff, which frame-work carries the wheel 10 and crank l. A pinion, p, which gears into the wheel 20, is attached to the rod 1 and carries it round with it. This pinion is so fixed that when requisite the rod z may be raised, so as to elevate the paddle h out of the mold, the rod slipping through the pinion without putting it out of gear. The rod is raised by a hook at the upper end, (marked 21.) The vanes of the paddle It must not he too wide for the paddle to pass through the mold at the upper coupling, 0.
' The mold and chill in Fig. 2 (if the paddle h and frame I; with its gearing were removed) would represent theordinary mode of making heavy castings or rolls. The melted metal, descending the runner c, enters the mold through the gate (1. and rises in the mold and chill till they are filled. This mode of casting has a tendency, however, to throw all the dross, slag, and lighter parts of metal to the surface or circumi'erence of thecasting, while the heavier and best portions of the metal are in the center, and, as in making chilled rolls, it is essential to have a good surface on the rolls, it becomes a matter of importance to throw the best and heaviest parts of the iron to the circumference, and to efl'eet this a rotary motion must be communicated to the metal as it rises in the mold and chill. This rotary motion was formerly obtained by simply stirring the metal by hand with a rod or stick; but this method was attended with danger, and was incom enient, diliicult in its operation, and uncertain in its results.
My invention consists in a new and useful mode of communicating this requisite rotary or swirling motion to the melted metal, which I effect by means of the paddle or fan h, (see Figs. 2 and 3,) which is fixed and attached to the rod 1' in the mold, as before described. This paddle is caused to revolve by turning the crank l, carrying the wheel 20, which moves the rod '1', to which the paddle is attached. The paddle turns round in the lower journal, I), and the melted met-aheritizring the mold in the lowercoupling, c, meets the paddle as it rises in the mold, and by the action of the v-anes turning round in the rising metal produces a complete swirl or'lotary motion which.
continues until the roll is cast.
' but \Vhat I do claim as my invention is- The combination of the paddle or fan h with the rod 5 and rod 0' and the frame-work and gearing for giving motion to the fan for the purpose of producing the rotary motion of the iron in casting chilled rolls and similar castings.
