1 0 all whom it may concern:

Be it known that I, CARL P. AsrR oM, a citizen of the United States, and resident of East Orange, in the county of Essex and State of New Jersey,have invented certain new and useful Improvements inHot-Metal Ladle-Cars, of which the following is a specification.

This invention relates to the handling of hot metal such as molten iron and steel and the object of the invention is to retain so far as possible the'heat of the metal during the transfer thereof from the furnace to the casting pit, or'other point. In such transfer the hot metal is usually transported in an open pouring ladle.

The invention provides a ladle or car body with. a heat retaining cover secured in position in such a way as to remain in position during the pouring and without interfering with such pouring operation, or other uses where retention of heat is not desired.

The invention will be more fully understood by reference to the accompanying drawing forming a part of this specification, wherein Figure 1 is an end view of a car showing the ladle in position thereon and equipped with a heat retaining cover, the ladle and a part of the cover being indicated as broken away and appearing in section.

Fig. 2 is a broken front View of the ladle and its cover.

The hot metal car which is designated 5 may be of any usual or preferred construction and is shown as constructed to support the ladle 6 which is provided with pouring trunnions 7 and 8 journaled in the bearings 9 and 10 provided on the car body. In addition, this ladle is shown as provided with the usual centrally disposed trunnions 11 for the engagement of the crane hooks, or other lifting device.

]2 designates the cover for the ladle which is shown as provided with a heat retaining lining 13 and is furthermore shown as cut away at its opposite edges at 14 in line with the pouring spouts 15 of the ladle.

. This cover is also shown provided with a suitable yoke or lifting device 16 by which the same may be transported and applied to or removed from the ladle.

his removable cover is detachably secured in position closing the mouth of the ladle by fastenings comprising in the present instance coupling bolts 17 engaged benor-METAL LADLn-CAR- specification'of LettersPatent. Patented lily 27 1920.

tween the flange portion 18. of the cover and the abutments or brackets 19 on the rim portion of the ladle. This construction provides a secure means for holding the cover in position on the ladle irrespective of the tilted position of the ladle, and also gets the fastenings away from the'heatj 'At the same time the cover maybe readily released by loosening and detaching the. said coupling 1 bolts.

The notch or notches 14 in the rim of the cover which register withthe pouring spout or spouts provide an easy entrance or exit for the molten metal so that'the' cover may remain in place both when the ladle is being charged and discharged. In Fig. 1 I have indicated how with this construction the ladle may be charged directly from the spout 20 of the furnace, with the cover in position.

21 is a wedge block or chock to support the frame bolster 24 during dumping so as to maintain a short pour on a fixed trunnion axis, to runner 22. 23 is a support for chock 21, the latter being operated by levers dumping.

lVhennot desired for hot metal, as for cinder, etc., the cover can be removed making an ordinary open ladle, or car body and also when cleaning or relining is desired.

The cover consists of a continuous ring frame with the opposite recessed portions at 14:, which permit expansion and contraction without loosening the brick lining. This ring has an inner flange which supports the bricks, and also fits the top of the ladle, and the bricks are protected from rough handling of the cover by the top metal plate secured to the ring outside the bricks.
