The guidance nite angular"relationf to ltheJcarfnia'ge rTandV prevents Sit "from swinging when. thefcarriage is moved, or the turret support B turned with a full ladle thereon.

The pouring ladle, support B .is rotatably mountedon the portion 25, and comprises kwhich is'held in placeA by a gasket 35. The 'gasket 35 is provided with a. projecting flange 36 spaced from the portion 25 of the yoke 24 and providing a space in which is placed a packing 37 held in place by a pack- Y ing gland 38. The gland and the gasket 35 are secured in placeby bolts 39 and 40. The lower portion of the sleeve 26 is provided with an annular flange 41 forming a shoulder on. the sleeve against which is placed a gasket 42 which serves to hold in place a lower roller journal bearing 43 and which engages a sleeve-supporting ball bearing 44 mounted on the plate 45. The plate 45 is provided with a spherical recess having an opening at its center to receive a bolt 46 which is passed through an opening in the closed end of the portion 25 and receives a spherical. washer 47 and nut 48 which hold the plate 45 in place and the sleevel 26.0n the cylindrical portion 25 of the yoke 24. The opening in the annulailange 41 is closed by a covei` 60 held in place by screws 61. A.

yFrom the foregoing description, it will be seen that the sleeve 26 together with the arms formed by the outward extensions of its flange 27 and the members 29 constitute a strong supporting frame for the pouring ladles, by lvirtue of the fact that the radially projecting supporting arms. are braced with reference to the sleeve both horizontally and vertically, by the flange 27 and the ie-en-.

forcing rib or web members 28 and 29. This fra-me is anti-frictionally journaled about the lower portion 25 of the upright 21 by the rollerbearings 34 and 43, and is anti-frictionally supported by said upright through the ball-bearing 44:

The elevator a is raised and lowered by means of the electrically operated hoisting VVdevice 13, which operates the drum 14 to wind and unwind the cable 15 which passes from the drum 14 down through the carriage 7 and the guide frame Vformed by the parts 16, etc., to and around the pulley and has its end secured to an angle bar 49 carried by the members 12. As the cable 15 thus takes hold yon the upright 21 at the ed on a shaft 52 journaled in the side plates Y 9 of the carriage 7. On the sha-ft 52 there is Secured a pinion 53 which engages with a gear 54 secured on the adjacent axle 8.

n operation, an empty ladle .32 is positioned infront of the source of supply or bull ladle 55 and shifted back and forth by operation of the chain 51. When this ladle 32 is filled, the elevator a is raised by means of the hoisting device 13, bringing the lugs 30 up so as to engage the trunnions 31 of another empty ladle 32 held by the hooks 56 of the monorail carrier 57. The elevator t is raised further so asv to lift this empty ladle from the hooks 56 and is then rotated so as to place the ladle 32 already filled adjacent the hooks 56, whereupon the elevator is lowered to deposit this filled ladle 32 on the hooks 56. This filled ladle 32 is then conveyed to the pouring station bythe monorail carrier or traveller57, and the elevator a is lowered to bring'a second empty ladle 32 into filling posit-ion before the bull ladle 55.4 Inpractice, a plurality of ladles 32 are used, so that all. of the ladle positions but one on the ladle elevator are lilled with ladles. Under this condition, the vacant position filled by an einpty'ladle taken. from the monorail carrier 57, and when .the elevator is rotated tobi-ing the lilledladle in line with the .hooks 56 of the menor-ail carrier 57, an empty ladle is brought into position in front of the bull ladle. lillhen the-filled ladle is deposited onv the hooks, avacant position is made on the elevator to receive the next returned empty ladle. Lowering the elevator then places aneinpty ladle before the loull ladle in' position for filling, the pouring` ladle being shifted Yback-and forth by the operation of the chain 51 in order that it may be proporly positioned before the bull ladle as the bullladle is tipped to lill the pouring ladle, the tipping lof the bull ladle varying with the amount of molten metal it contains.
