APPARATUS FOR CASTING AND HANDLING PIG METAL.

SPECIFICATION forming part of Letters Patent No. 548,188, dated October 22, 1895.

Application filed January 10, 1895. Serial No. 534,459- (No model.)

To aZZ whom it may concern.-

Be it known that I, HARRY REID GEEK, a citizen of the United States, residing at J ohnstown, in the county of Cambria and State of Pennsylvania, have invented a new and useful Apparatus for Casting and Handling Pig Metal, of which the following is a specification.

This invention relates to apparatus for easting and handling pig metal; and it has for its object to provide a new and useful apparatus of this character essentially consisting of a rotating pig-bed, to provide for receiving the molten metal from the furnace, for casting and cooling such metal in separate blocks or pigs, and for delivering the cooled blocks or pigs onto cars or other desired point of deposit.

To this end the main and primary object of the present invention contemplates a pigmetal-handling apparatus that will obviate the many objections to the ordinary method of solidifying pig metal in separate stationary molds by providing means for effecting the solidification of the molten metal during the transit thereof from the furnace to cars or .other point of deposit.

With these and other objects in view, which will readily appear as the nature of the invention is better understood,'the same consists in the novel construction, combination, and arrangement of parts hereinafter more fully described, illustrated, and claimed.

In the drawings, Figure 1 is a side elevation of an apparatus for casting and handling pig metal. Fig. 2 is a transverse sectional view on the line :rscof Fig.1. Fig. 3 is an enlarged detail transverse sectional view of the endless roller-chain and one of the chills or molds detachably secured thereon. Fig. 4 is an enlarged detail side elevation, partly in section, of asection of the endless roller-chain and the chills or molds thereon. Fig. 5 is a top plan view of a short series of the detachable chills or molds.

Referring to the accompanying drawings, 1 l designate oppositely-located pairs of parallel truck-beams that have secured to the under side, at the opposite ends thereof, the depending bearing-hangers 2, in which are journaled the flanged wheels or travelers 3 that are adapted to run on the track-rails 4, that are suitably arranged on the floor of a casting-house in front of a series of blast-furnaces, so that the herein-described apparatus may be readily shifted from one furnace to another to provide for casting and handling the molten pig metal.

The wheeled truck-beams 1 support therebetween the oppositely-located upright-supporting frames 5, consisting of parallel frameuprights 6, connected at suitable points by the transverse frame-bars 7, and the parallel frame-uprights 6 of the frames 5 are secured in position between the parallel truck-beams of each pair so as to extend both above and below said truck-beams. The parallel frameuprights 6 of the upright-supporting frames 5 have secured to the inner upper and lower ends thereof the angle track-rails 8, which are also secured to the inner upper and lower ends of-the intermediate frame-uprights 9, that are located intermediate of the opposite upright-frames 5, and which are securely braced in position by means of the V-shaped brace-rods 10, that are passed around the lower ends of the frame-uprights 9, as at 11, and are secured at their extremities, as at 12, to the plates 13, connected to the upper ends of the frame-uprights 6, for the purpose of properly securing the upper pair of rails 8 to the said uprights 6.

The uprights 6 of the upright-supporting frame 5 have extended, from the outer sides thereof the offstanding braced bearing-brack-' ets 14,0n the outer ends of which are mounted the bearing-boxes 15, in which are journaled the shafts 16. The shafts 16, by reason of being mounted at the outer ends of the brackets 14, are located at the opposite ends of the frame composed essentially of the connected upright-supporting frames 5 and the wheeled truck-beams 1, and the said shafts 16 have mounted thereon the opposite-end pairs of chain-wheels 17, that are provided with spaced peripheral notched roller-lugs 18 to receive the flanged rollers of the endless roller-chain 19, and motion may be communicated in any suitable manner to either of'the end set of Wheels, in order to provide for imparting a slow motion to the said endless roller-chain.

The endless roller chain 19 consists of aligned pairs of link-platesfZO, overlapping each other at the ends and pivotall y connected at such overlapped ends by the cross-bars 21, that are extended beyond the outer sides of the retention of the rollers on the track-rails S and in the notched lugs of the chain-wheels while the chain is in motion, and the linkplates 20 of the chain are provided near their ends with longitudinally-disposed slots 25, that are adapted to removably receive the transverse tie-bolts 26, that are also adapted to be passed through the perforated attaching-lugs 27, projected from the lower sides and near the opposite ends of the detachable metal chills or molds 28.

The chills or molds 28 are adapted to be arranged on each pair of the link-plates 20, and the attaching-lugs of said chills or molds are projected therefrom in from their side edges, in order to fit inside of the link-plates to receive the tie-bolts 26, while at the same time not interfering with the free movement of the endless chain and the travel of the rollers thereof on the upper and lower pairs of track-rails. By reason of the specific manner of attaching the chills or molds to the endless roller-chain it will be obvious that said chills or molds may be readily removed or replaced at any time, and the said chills or molds are of substantially the same length as the link-plates, so that the chills or molds will be closely aligned to provide for the proper handling of the metal. The chills or molds 28 are provided in their upper sides with a series of mold pockets or recesses 29, that may be either longitudinally or transversely disposed of the body of the molds, and are of a shape to provide for casting the molten metal into the usual shaped blocks or pigs. The said chills or molds 28 are further provided at one end with integral transversely-disposed and triangularlyshaped joint-ribs 30. The trian gularly-shaped j oint-ribs 30 are projected above the plane of the molds and beyond one end thereof, so as to overlap one end of the adjacent mold to provide for substantially closing the joints or spaces between the ends of the molds to prevent the molten metal from working its way in between the chills or molds.

The wheeled support for the frame that carries the endless rollerchain allows the apparatus to be readily wheeled from one furnace to the other, so that one end of the up per side of the roller-chain may be brought under the metal spout-or trough 31, that provides for delivering the molten metal from the blast-furnace into the chills or molds of the apparatus. With the apparatus thus positioned the metal passes from the spout 31 into the chills or molds 28, which are thereby filled, and are then carried slowly forward by the roller-chain, so that by the time the chills or molds reach the chain-Wheels opposite the metal spout or trough the pigs will be sufficiently solid to be automatically dumped onto a car 32 or other point of deposit as the chills or molds pass around the chain-wheels referred to.

From the above it is thought that the construction, operation, and many advantages of the herein-described apparatus will be readily apparent to those skilled in the art, and it Will be understood that changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described the invention, What is claimed, and desired to be secured by Letters Patent, is-- 1. In an apparatus of the class described, oppositely located wheeled truck beams, upright supporting frames secured on said truck beams, upper and lower pairs of track rails fitted within said upright supporting frames and disposed at right angles to the truck beams, oppositely located chain wheels carried by the upright frames, an endless-chain engaging with the chain wheels and carrying rollers traveling on the track rails, and an endless series of chills or molds fitted on said chain, substantially as set forth.

2. In an apparatus of the class described, the combination of a suitably supported frame carrying upper and lower pairs of track rails, an endless roller chain consisting of aligned pairs of link plates provided near their ends with slots, cross bars pivotally connecting the overlapped ends of said plates and extended beyond the plates into spindles, and rollers mounted on said spindles and traveling on said track rails, a series of aligned metal chills or molds provided with opposite pairs of depending perforated attachinglugs fitting inside of the link plates of each pair, and transverse tie-bolts passed through the slots of said link plates and the perforated lugs of said chills or molds, substantially as set forth.

'3. In an apparatus of the class described, oppositely located wheeled truck beams, oppositely located upright supporting frames secured on the truck beams between the wheels thereof, upper and lower pairs of track rails fitted within said upright supporting frames at the upper and lower ends thereof, offstanding bearing brackets projected from the outer sides of said upright supporting frames, end chain wheels mounted on said bearing brackets, an endless chain carrying rollers traveling on the track rails and engaging with said chain wheels, and an endless series of metal chills or molds detachably secured on said endless chain, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

HARRY REID GEER.
