APPARATUS FOR MAKING AND TRANSFERRING PIG METAL.

SPECIFICATION forming part of Letters Patent No. 362,670, dated May 10, 1887.

Application filed December 9, 1886. Serial No. 221,075. (No model.)

To aZZ whom it may concern:

Be it known that we, JOHN R. SELL and LEROY A. SELL, both of Johnstown, in the county of Gambria and the State of Pennsylvania, have invented certain new and useful Improvements in Apparatus for Making and Transferring Pi g Metal, of which the following is a full, clear, and exact description.

The object of our invention is to provide an apparatus for making pig metal, and then transferring the mold or chill carrier and its molds, chills, or troughs bodily to a point adjacent to a track and then dumping the mold or carrier, so as to cause the then hardened or formed pig metal to fall into a car on the said track.

The invention consists of various parts and details, and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of our improve ment. Fig. 2 is an enlarged sectional plan view of the same on the linezz of Fig. 1. Fig. 3 is an end elevation of one of the drums. Fig. 4. is a plan view of the stationary bed and the carrier-bed. Fig. 5 is a vertical sectional elevation of the same on the line m w of Fig. 3,

and Fig. 6 is a vertical cross-section of the same on the line y y of Fig. at.

At a suitable distance from the tap-hole of a cupola or blast furnace is arranged the iron casing or bed A, in which is held the pigmetal carrier B, provided with a number of transverse brick troughs, chills, or molds, C, which open at oneend into the longitudinal brick trough, mold, or chill D, held in a suitable metal casing, D, pivoted to the stationary bed or casing A, and extending on one side thereof. The trough or chill D is somewhat higher than the series of troughs or chills C, so that when the molten metal is run from a eupola or blast furnace into said trough or chill D it will run thence into the series of troughs or chills O, as will be readily understood in connection with Figs. 4, 5, and 6 of the drawings. The pig metal will be of less thickness at the juncture of the chills C and trough D, which allows of it being more readily broken when the trough D is swung upward. Additional braces, D assist in supporting the casing D, and rest against the side of the bed A. A U-shaped frame, E, is pivoted on the ends of the casing or bed A, and can be looked over the carrier-bed B in order to hold the pig metal within the chills or molds 0 when the hinged trough D is forced upward to break the pig metal at the juncture of the trough and chills or molds by means of swivel-hooks F, secured to the bed B, as shown in Figs. 4, 5, and 6.

The top of the carrier-bed B is provided with a number of hooks or staples, G, and on the two ends are securedt-hellooksG,wl1iel1 hooks G and the hooks-G are connected by suitable rods or chains, H, (see Fig. 1,) with the crossbeam H, hung on a chain, I, passing over a pulley, J, mounted on a truck, K, running on the track L, supported in any suitable manner either from above, as shown, or from below. The chain I passes from the pulley J to the drum M, placed loosely on the shaft 0, mounted in suitable hearings on standards at the inner end of the track L, and provided with suitable means for rotation.

The drum M is provided on one end with clutch-teeth, which, when the drum is moved sidewise, engage with similar clutch teeth formed on the clutch-collar M, secured on the shaft 0. A lever, B, engages the drum M, and serves to move the latter sidewise into or out of contact with the clutch-collar M. The drum M is also provided on its other end with clutch-teeth,which engage with similar clutchteeth formed on the clutchcollar M secured to the track L.

A chain, Q, is fastened by one end to the front of the truck K, and then passes over and around a drum, Q, placed loosely on the shaft Q mounted in suitable hearings on the track L, below the shaft 0, and is rotated with the latter by suitable connections. The drum Q is provided on one end with clutch-teeth,which engage similar teeth in a clutch-collar, Q", secured on the shaft Q and on the other end of the said drum Q are similar clutel'i-tceth, which engage the stationary collar Q, secured on a standard rising from the inner end of the track L. A lever, Q serves to move the drum alternately into and out of contact with the said collars Q and Q. The chain Q passes from the drum Q to and overa pulley, Q, mounted near the rear end of the track L, and then passes to the rear end of the truck K, and is secured to the latter. a

A chain, B, is secured by one end to a drum, R, placed loosely on the shaft R mounted in suitable bearings on the standards above the shaft 0, and is rotated with the latter by suitable means. The drum R is similar in construction to the drum M, and is moved alternately in contact with the clutch collar on the shaft R, and with a stationary clutch-collar secured to the standard by means of the lever R The chain B passes from the drum R to a pulley, S, journaled in bearings at and above the outer end of the track L, and its free end hangs down. The shafts 0, Q and R are rotated simultaneously by suitable gear-wheels or other means.

The operation is as follows: The carrier-bed B rests in the stationary support or bed A, as shown in Figs. 4 and 5, and the pig metal is formed in the troughs C, which are charged by the longitudinal trough D. After the pig metal is formed in the troughs or molds G,then the trough D is swung upward, so that the metal in the trough O is loosened or breaks its connections with the trough D, the bar E serving to hold the pig metal in the molds O, as before stated. The hooks F are then removed from the U-shaped cross-bar-E, and the latter is swung to the rear upon the upper end of the stationary support or bed A, whereby the carrier-bed B becomes free, and it is now raised out of the stationary support or bed A by throwing the drum M into contact with the clutch-collar M, secured on the rotating shaft 0, so that the chain I is wound up on the said drum M, and then lifts the carrier-bed upward and out of the stationary support or bed. The drums Q and R are held in contact with their stationary collars and do not rotate. As soon as the desired height is attained, then the drum M is uncoupled fromthe collar M and locked in position by engaging the stationary collar 1W. The drum Q is then moved in contact with its clutch-collar Q, so that the truck K is set in motion on the track L and carries the carrier-bed B to a point above the track on which are the cars to be loaded with the pig metal. As soon as the truck K arrives at the desired position over the cars, then the drum Q, is disengaged from its collar Q and locked in position by being thrown into engagement with the stationary collar Q". The free end of the chain R is then hooked to the staple V at the rear of the carrier-bed B, and the drum B is connected and moved into contact with its clutch-collar on the shaft R whereby the drum R is rotated and winds up the chain R, which tips the bed B over to the front, so that the pig metal in the trough 0 slides out and into the cars. In order that the pig metal may readily slide out of the troughs or chills 0 they are formed with open forward ends, as shown in Figs. 4 and 6, which are adjacent to the inner edge or side of the feed trough or chill D, which latter trough is provided with short spouts or outlets registering with said open ends of the troughs or chills O. The empty carrier-bed is then returned to the stationary support or bed by causing the shafts O, Q, and R to revolve in an opposite direction, so that the chain B is unwound and the carrier-bed B again assumes its normal position. The drum R is then disengaged from its shaft-collar and thrown into engagement with the stationary clutch-collar, so that the chain B is held in its normal position and is then unhooked from the carrier-bed B. The truck K is then returned to its normal position by means of the chain Q and its drum Q, after which the carrier-bed B is let down into the stationary support or bed A by means of the drum M. The molds O are again charged, and the abovedescribed operation is repeated.

By forming the trough, molds, or chillsof brick instead of casting the pig metal in sand, as is customary, the bars come from the molds or chills clean and free from sand; but I may use iron molds or chills in place of brick, and, should it be found desirable at any time, the movable or carrier bed may be provided with the usual bed of sand-molds, as the pig metal could be transferred in either instance, the carrier-bed being removable and capable of being dumped, as before described.

Having thus fully described ourinvention, we claim as new and desire to secure by Letters Patent- 1. The combination, with the bed A, the trough D, and the U shaped locking-frame E, pivoted at its ends to the ends of the bed, of the carrier-bed B, having molds, and pivoted hooks F, adapted to engage the cross-bar of the locking-frame, substantially as set forth.
