LADLE CONSTRUCTION.

To all whom 'it may concern: handling the ladle is easily and quickly se- Beit known that I, RICnARD H. STEvEKs, cured in place, and is removed after placing of Munhall, Allegheny county, Pennsylvania, the ladle in place on the trunnion supports. have invented a new and useful Ladle Con- -A lug l1 1s provided on each side of the I :IPdIQ, to which any suitable tilting device may be'secu'redwhen tilting or dumping the car'in the ladle supports 4 on the car body. In dumping the ladle on the car, a chain hook or other device is attached to one of clear, and exact description, reference being bad to the accompanying drawings, forming part of this specificatiomin which- Figure l is a longitudinal side elevation of a ladle car having a ladle and ladle supports constructed and arranged in accordance with my invention; Fig. 2 is an end elevation of the same showing the arrangement of the trunnions and trunnion supports, and showing the lifting means by which the ladle is handled in being removed from and placed on its supports.

My invention relates to the construction in either'direction. At the beginning of'the tipping operation, he ladle is supported the trunnions 6 and 7 a in the seats 6 and 7 tipped about the axis of the trunnion 6 or 7 until the trunnion 5" or 8, depending on the direction in which the ladle is :being tipped, engages with its trunnion seat 5 or 8, and on continuing the dumping operation the ladle is then tipped about the axis of the trunnions 5 or 8.

After the ladle is emptied, the direction of 'movement is reversed and the ladle again assumes the position shown by full lines in such as molten iron and blast furnace cinder, and it more particularly relates to ladles which are arranged to be tipped or tilted in emptying them of their contents. The object of my invention is to provide require them'to be body. I I The advantages of my invention will be apparent to those skilled in the art. The aparms 10 being employed to handle the paratus is simple, and is easily kept in r ladle when the ladle is removed from its pair.
