Specification of Letters Patent.

Application filed Novemberl), 1913. Serial No. 801,818. i
To @ZZ whom it may concern Be it known that I, VILLis T. Hunsr, a citizen of the' United States, residing at Pittsburgh, inthe `county of Allegheny and State of Pennsylvania, have invente-d certain new and useful Improvements in Casting Mechanism, of which the following is a specification.
My invention has for its object to provide continuous casting mechanism for molten metal for forming it into pigs; discharging the saine at an assembling position; cooling` the assembled pigs in a receiving vat or receptacle, especially adapted to the purpose; and then removing the pigs in quantities for shipment or storage.-
rlhe apparatus is of thesame general type in common use, wherein a series of loosely connected molds in the `form of an endless conveyer are passed underneath a supplying spout from any suitable vessel containing the molten metal, `andare cooled -in their passage along tlie"conveyer,`with theaddition of water-spraying mechanism if de sired, the pigs being discharged from the molds in sufficiently cool form to retain their shape. I
In the present invention I utilize one or more continuous conveyers of suitable construction, kdischarging the pigs into a receiving vat where they are cooled by a water spray, the vat being provided with a filtering bottom adapted to allow drainage of the water, and without loss of any of the metal.
@ne preferred arrangement of the apparatus is illustrated in the accompanying drawings, in which:
Figure 1 represents a general plan-view, partly broken away, showing the distributing ladle and. trough, a pair of conveyers,
' the coolingvat, lifting crane, etc. Fig. 2 is a view ofthe apparatus in side elevation, Fig. 3 is an enlarged sectional detail view of the filtering cooling vat and its parts. Fig. 4 is a 'transverse sectional viewshowing the magnetic lifting crane and the surrounding construction with Figs. 5 and 6 are detail sectional views showing a plurality of the connected molds. Fig. 7 is a sectional detail view showing a modified construction of cooling vat.
The molten metal to be formed into pigs, as molten iron, is brought by a suitable vessel, as ladle 2, upon a buggy traveling on .tracks ,3., or by other suitable means, into yElaid molds, which are of well-known construction, and as indicated in Figs. 5 and 6, are provided with longitudinal receiving recesses 7, and each inold overlaps the neXt adjacent niolds in the manner indicated at 8,' whereby to prevent loss of surplus metal, as
is well understood.
The molds are connected together by suitable linkA mechanism which is mounted upon the driving head and supporting tail wheels, 9, 10, forming an endless conveyer, two such complete conveyers being shown in the drawings, opeiating side by side for increased capacity. I,
rllie head or driving sprocket wheels 9 ar geared in any suitable manner, as by gearing ll'with a motor 12 of any suitable type, whereby to actuate the mechanism, the series of molds being preferably slightly inclined upwardly toward the discharge points.
it the terminals of the conveying movement, the molds pass around over lhead wheels 9, the formed pigs falling by gravity upon inclined chutes 18, by which they are discharged over and downwardly into the pig` cooling vat 14. Said vat is of considerable size, having surrounding walls 15 of concrete or other suitable material and a t bottom 16, preferably sloiiinn1 toward a centrallv arranged sewer outlet 1'?. Within the walls l5, and above bottom 16, are laid a series of .filtering elements in layers ras shown, a bottom layer 18 of crushed stone, a
y it, are water spray pipes 21, 21, leading from any suitable source of supply and having proper controlling valves, etc., by which cooling water is sprayed upon the accumulating pigs as they are received in the vat, further cooling them for transportation. The water passing from the surfaces of the and downwardly through the filtering i sewer conduit 17.
beds finally 'pt'.sses'oli1 through opening 17 to the sewer, any loose particles of metal being arrested and retained in the bed of the vat upon the surface of the uppermost layer 2O of limestone or gravel. An especial advantage of such construction and operation is that any spraying of the pigs in the cars is rendered unnecessary, avoiding objectionable accumulation of water and ice, the pigs be ing delivered to the cars in dry condition, while :also protecting the cars from the burning eifect of too hot metal.
In Fig. 7v I show a modified construction of cooling vat in which the walls 15 extend considerably higher above the bottom 16 and above the uppermost layer 20 of limestone or gravel. By this construction I provide a water holding cavity or bath 3U for the ypigs of considerable depth, to which water is supplied by a supply pipe 21'r in any desired volume for maintaining a body of water within vthe surrounding walls 15. The water thus completely or practically covers the accumulating pigs, passing o' downwardly to the sewer 17 through the uppermost supporting layer 20, the sand layer 19 and 'bottom layer 18 and finally to The object in placingthe sand ffltering 'layer below the gravel or sandstone surface llayer is to prevent adherence of the sand to the pigs, while `at they same time insuringl ythorough 'filtering `of the water.
For the purpose of removing the pigs, I provide a vlifting magnet 22 of well-known construction, suitably vconnected with any source of "current as by lconductor 28. `The magnet depends from la traveling carriage or `trolley 24, mounted upon. the supporting frame-work and tracks 25 of a traveling crane, which in turn is mounted by its wheelsv 26 upon supporting tracks 27, whereby the crane. may have any desired or necessary travel. It will be 'understood that the crane, which is'of well-known construction, is provided with suitable controlling mechanism,
whereby it may be operated to raise andL lower the lifting magnet and to shift the load longitudinally or laterally to discharge into Va receiving car 28 at either side of the cooling vat, or elsewhere, as preferred.
The -advantages of Athe invention reside in 2its facility for direct, economical and rapid 'treatment of the metal, prompt and eiiicient cooling; salvage of any surplus or loose metal within the cooling vat, removal of ythecooled pigs as they accumulate in the vat, and prevention of'any necessity of delivering hot pigs to the car or other transporting vessel. The accumulated pigs in the vat, v'being closely `associated together, are in convenient position for attachment and lifting 'by the magnetic crane, thereby increas` ing the vcapacity and usefulness of the crane in fgatherimgg; and moving large numbers of sara to insure their settinO'. D
The pigs in transit may be preliminarily cooled by means of spray pipes 29, as shown in Fig. 1, such spray pipes being located at a suitable distance above the traveling mold. These are of well-lm 'own construction, having series of jet openings for delivering water downwardly over the molded pigs.
The apparatus may be builtin any'desired capacity, the length of the conveyer, the size and form of the molds being within the normal requirementsof the installation, andthe invention may be otherwise changed or varied by the designing'engineer or skilled meclianic, within the scope of the lfollowing claims. y
