comprising means4 forautomatically stripping the inold from the ingot at the strip- As is well known to those skilled in the art, it is ordinarily the practiceto employ :a non-sectional or solid mold arranged in an u right position upon the 4car platform. l T 's car isi'irst run -tothe point Where the Inoldwill Vreceive the molten metal as it flows fromthe ladle, and when the mold is filled 'the car is runalong the track to the strippingstation, that i-s, to a point opposite `215 .what is called the soaking pit-.v At this point, the mold is stripped orlifted olf the ingot bythe usual appliances employed for that purpose,4 but as is also well known, this stripping process, with 4the ordinaryfacilitiesand with'4 the ordinary non-sectional Iniold, is frequently-attended with difficulty, inasmuch as the ingot is liable to stick .to the mold and under such circumstancesit often becomes necessary -to shatter the mold tol effect its se aration from 'the in ot.

V It is there ore thepurposeoft e present y invention-to providean improved ingot mold so constructed and operated as to eifect an fautomatic stripping' of the mold fromthe 40 ingot at the stripping point, thus obvi'ating al1 of vthe d-iiiiculties heretofore existing to. the common stripping methods and -atv the same time providing reliable means foralways leaving the ingot free from the'inold,

in itsl general organization a body 7 carrying the wheel axles Sonfiwliich are mounted .the

-wheels 9 that travelo'ri the track rails 1D.

' The platform of tlegjcar carries thereoifa mold base '11, that isa-base upon which is Supported the ingot 1110141(3a-signmed` i; its .entiretr by the lptter M` @ll-.This mold base 11 preferably consists of affseparate 'platede-A tachably mountedv 0r securedbn top ofthe-j car platform. The detachable vmounting o f` 85 the mold base maybe eifet'xted-A in a variety of ways, but a simpleexpedient-fthat may be resorted' to is suggested in the drztwinga viz':` the feature ofvproviding the sai-dbase at its corners or other suitable point'swith depending holdingv lugs l1 engaginginkeeper' sockets 11.h in the car platform, but it will be understood that equivalent `fastenings may In this connection, it will be observed that the idea of'using a detachable and replaceable mold base' is to permit the same to bel readily re placed when-burned out witlioiit'in any vwise interfering with the bed of the car or the i mechanism carried thereby.

. The ingot mold M is preferably vof the ulpwardly tapering type, but according to'v t e present invention', consists of a pair ofI matching sections l2, suitably hinged, Aas shown at 13, to the base. The lower edges of these mold sections 12 are preferably conv-' vexed, as indicated at 12, to register in c0rV respond' ly concaved seats 12b provided in'- .l the mold ase, thus forming an interlocking il() ilar4 joints, for a similar purpose, are' provided between the meeting edges of the. separate mold sections.

thereof are crank shafts 16, the cranks 17 of which operate vthrough openings 18 formed in the car body. These cranks have pitmen connections 19 with .the mold sections 12, the pitmen'. being pivoted to ears 20 projecting' from the outer sides of the sec- A driven' shaft 21, journaled longitudinally upon -the under side of the car body, has bevel gear connections 22 22l with the crank shafts, so that their simultaneous rotation in opposite directions effected. A driving shaft 23, journaled in suitable boxes 24 upon the under side of the car body transversely thereof, has a worm 25 that meshes with a worm wheel 26 mounted on the Shaft 21. It will thus be clear that if i the driving shaft 23 is rotated, the shaft 21 will be turned, thereby rotating the crank shafts 16 and the cranks 17, forming parts thereof. As these cranks swing away from yeach other, the mold sections will be swung apart, and consequently stripped from the ingot cast in the mold. Upon th'e rotation of the shaft 23 in an opposite' direction, the mold sections will be swung together or into assembled relation.;

Different means may be employed for rotating the driving shaft 23. In the form of construction, which is probably preferred, a

' rack 27 is mounted between the track rails at or adjacent to the stripping point, and a gear 28, fixed to the driving shaft 23, is so positioned that it will engage the rackwhen the car is moved over said rackpthus the separating mechanism will be operated and the mold automatically stripped from the ingot. When the mold is opened, the ingot can be readily removed from the car, as will be obvious, and upon the return of the car from the stripping point, the mold will automatically c ose. The worm gear connection between the driving and -driven shafts is important, as it constitutes a lock for holding the said sections against accidental By way of -illustrating the .wide range of modification'that may be resorted to in carout the invention, there is suggested in Fig. 6' another form -of operating mechanism that may be employed. 'j According to this suggested construction, a suitable motor 29 may be arrangedalongside of the track providing means for driving a longi- -tudinally shiftable shaft 3() carrying a gearchanical means (not shown) to provide for shifting the gear Wheel 31 into and out of mesh with the gear wheel 28. Hence, when the cai' is moved to the stripping station; the sha-ft 3() is shifted into engagement with the gear wheel 2S, as shown in Fig. 6, whereupon it will be obvious-that the mold can be opened and closed as described.

Freni the foregoing, it is thought that the construction, operation, and. many advan tages of the herein described invention will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size, shape,

proportion, and minor details of construc-v tion may be resorted to wvithout departing from the spirit or sacriiicing any of the ad vantages of the invention.
