APPARATUS FOR EXTRACTING INGOTS FROM MOLDS.

SPECIFICATION forming part of Letters Patent No. 667,577, dated February 5, 1901.

Application filed November 29. 1898. Serial No. 697,766. (No model.)

To LtZZ whom 't may concern:

Be it known that I, GEORGE K. ROBERTS, a citizen of the United States, residing at Joliet, in the county of Will and State of Illinois, have invented certain new and useful Apparatus for Extracting Ingots from Molds, of which the following is a specification, reference being had therein to the accompanying drawings and the figures thereon, which form a part of this specification.

My invention relates to the manufacture of steel ingots, and it has for its object to provide a serviceable and efficient apparatus for handling the molds and their cars or buggies and removing the ingots from the molds.

In steel manufacturing and converting plants the molten steel is poured into molds which are stationed in an upright position on cars orbuggies, and When the steel has cooled sufficiently to form a solid mass the ingot is removed from the mold, the removal being effected as soon as possible afterthe metal becomes solidified in order to retain and utilize the heat therein in the further working; of the steel. My invention is designed to effect such manipulation of the cars, molds, and ingots as will most fully meet the requirements of economical and efficient steel-manufacturing plants, and it accordingly consists of means which will be now described, reference being had to the drawings, in which- Figure 1 is an end elevation of the appa-` ratus embodying my invention, the supporting masonry being shown in section. Fig. 2 is a side elevation of the apparatus shown in Fig. l. Fig. 3is a plan view of a pair ofingotmolds and their retaining-arms.

In the apparatus shown in the drawings the railway-trackl, upon which the ingot-cars 4 are transported from the point where the molds are filled, terminates at one side of an elevator-well, a similar track 2 being located in a lower plane and terminating adjacent to the elevator-well on the opposite side from the track 1. The elevator-platform 3, which is located and operates in the well, is provided with a section of track of sufficient length to receive thereon a plurality ofingotcars and is so arranged and, operated by means of the piston 5 of a hydraulic cylinder 6 as to be moved vertically the necessary distance to bring its track into alinement With either the track l or the track 2.

Journaled in suitable bearings at the sides of the elevator-well are two rock-shafts 7, having rigidly fasiened thereto upwardlyprojecting arms 8 and downwardly-projecting arms 9, the latter of which are connected to the pistons of hydraulic cylinders 10 for the purpose of moving the upper ends of the arms 8 inward to engage the elevator-platforn 3 and serve as supports therefor when said platform is in the position shown in Figs. 1 and 2 and for the purpose of moving said arms outward when it is desired to lower the platform.

J ournaled in suitable bearings at the top of the elevator-well and at right angles to the shafts 7 are two. rock-shafts 11, to each of which are rigidly fastened the lower ends of a set of upwardly-projecting arms 12 and the inner en ds of one or more laterally-projecting arms 13, the outer ends of the latter being connected to the pistons of hydraulic cylinders l l. Two rock-shafts 15, located substantially parallel to and above the rock-shafts 11, are journaled in suitable bearings supported by cross-beams 19, forming paris of a framework 20. Each of the rock-shafts 15 is provided with a plurality of pairs of in wardlyprojecting and approximatelyhorizontal arms 16, there being one pair of these arms for each mold to be handled by my apparatus. The rock-shafts 15 are actuated by means of arms 17, the inner ends of which are rigidly attached to the said shafts and the outer ends of which are connected to the pistons of the hydraulic cylinders 14 by means of rods 18.

Supported by the bars 19 of the framework 20 are hydraulic cylinders 21, so located and arranged that their pistons 22 will operate vertically and be in position to severally enter the molds handled by my apparatus.

As indicated in the drawings, each ingotcar will support one pair of ingot-molds 23 and the elevator-platform 3 will accommodate three cars. It Will be understood, however, that my invention is not limited as regards the number of cars handled at one time or the number of molds per car. In order that my apparatus maybe operated in the manner intended, each mold should be provided with position to support the molds.

some means with which the free ends of the arms 12 may engage When said arms are iu I have shown each mold as provided with lugs 24: on two of its opposite sides, so located as to perform the desired function; butit will be underslood that other means might be employed.

In utilizing my invention for haudling ingot-cars and their loads and extracting ingots from the molds the loaded cars are received by way of the track l from the location where they Were filled with molten steel and are run upon the elevator-track, the elevator being in the position indicated in full lines in the drawings, the upper ends of the arms 8 being in engagemeut with the platform, so-as to hold it securely in that position, and the nolds being located directly under the corresponding pistons 22 of the cylinders 21. The elevator will then be preferably raised a short distance and the upper ends of the arms 12 moved inward into contact with the molds by means of their Operating mechanism, so that said ends will be located beneath the lugs 24. The arms 10 will be simultaneously lowered, as indicated in the drawings, so that their ends will rest against the sides of the molds, near their npper ends, in order to serve as retainers to prevent the molds from swayin The elevator will then be lowered to the position indieated in the drawings, and since the molds are now supported by means of the arms 12 the ingots are supported solely by the cars. In case any of the ingots stick to the molds to such an extent that the action of gravity does not efiect their separation the pistons 22 of cylinders 21 may be actuated to force the ingots out of the molds and onto the cars. After all the ingots have been separated from their molds the arms 8 will be moved away from the elevator-platform and the latter lowered by means of its Operating mechanism, so as to bring its track into the plane of track 2, in which position the tops of the ingots are beneath the bottoms of the molds, and the cars on which the ingots are supported may be run out upon the track 2 and the ingots unloaded theref'om by suitable means and at the point desired. After the cars are unloaded they may be returned over the track 2 to the elevator and again elevated to receive the molds, the arms 12 being moved away from the latter, so as to permit them to rest upon the cars. The cars hearing the molds may now be run out upon the track l and hauled to the location of the ladle, to be again filled. If desired, the apparatus may be of such dimensions that the cars may be raised to such height above the track l, in ordertobring the supporting-arms for the molds into operative engagement therewith, that when the cars are again lowered to the level of the track 1 the tops of the ingots will be beneath the bottoms of the molds.

The apparatus may also be so constrcted and arranged as to dispense with the elevation of the cars above the track l for the purpose of enabling the free ends of the arms 12 to pass beneath the lugs on the molds.

Other Variations in the form and a-r'augement of parts may be made without departing from the spirit and scope of my invention, and I therefore desire it to be understood that my invention is not limited as regards the specific number, location, or form of parts utilized in practicing my invention.
