Fig. 6 is a plan View of one of the table driving units; and

Fig. 7 is an end elevation of one of the table driving units.

It is an object of our invention to provide an improved casting plant of the type wherein a moving table carries the molds pastthe point at which the metal is poured.

t is also an object of our-invention to provide an improved traveling table for car rying the molds past the pouring point and to provide a suitable driving means for a table of the type described. l

With these and other objects in'view our invention comprises a circular traveling table or turntable 1 enclosing an area in which are placed the drag molding machine 2, roll-over machine 3 and the cope molding machine 4. These machines are positioned so as to be supplied with sand from an overhead sand bin carried upon the foundations 5. OVVithin the area enclosed by the table there are also mounted a cope jolting machine 6 and a drag jolting machine 7, both machines being mounted so that the sand from the copes and drags will fall into a sand pit 8 formed beneath the jolting machines 6 and 7. The pit 8 extends beyond the traveling table 1 and mounted above this portion ot the pit 8 is a Wheel jolting machine 9. Between the jolting machine 7 and the molding machine 2 there are provided a plurality of gravity conveyors 10 thatprovide storage space for the drags while cooling and are served by traveling hoists on an overhead monorail 11 at one end and on an overhead monorail 12 at the other end While between the jolting machine 6 and molding machine 4 there are a plurality of 55 tracks 13 joined by transfer tracks 14 that provide a means for moving the buggies on which" the -copes -and chills' are carried. Leading 'fromonef track 13 is a `transfer grthe -loaded'bu'ggies tothe storage tracks 16".5VV The monorail"12 connects with a monorail 17 thateXtends above the center line of track :15 thatprovides ameans for convey' G0 the table for more than half'the circumfer- 65 ence of' the table and is provided with a spur or extension 18 :which goes to the rollover machine ,3; spurs`19, 20, and 21 which join fsoas to form complete loops serving the molding -*machine 4; a spur 28 extend` 70 ing without'tlie'table area; and spurs 22, 23, 24 and .25 which 'join forming loops for the routingof a pouring ladle from a' ladle hoist 26 in `ront of the bull ladle 27 to a pouring position over the traveling table 1 7 5 and back tothe ladle hoist 26.

In .the operation of the plant, a drag is taken from the conveyorlO and' placed on the molding machine 2 by means of a hoist on the monorail 12. When'filled with sand, 80

the dragis turned over on the roll-over machine then picked up by means of a hoist on the monorail 18 and placed onvthe traveling tablel1, the cores -being placed after the drag is placed on the table. A cope and 85 chill, secured together in any desired way, are brought from a storage track 16 and lifted from the buggy onto the molding machine 4 by means ot a hoist on the monorail 21. Whenilled with sand, the cope and chill are lifted from the molding machine 4 by means of a hoist on the monorail 19, turned over while supported from the monorail, the chaplets placed and the chill oiled and then moved along on monorail 17 and 95 lowered down and clamped in position-on a drag'that is being carried to the pouring position on the table 1.

The ladles, filled from the bull ladle 27 are raised by the ladle elevator 26 so as to be engaged and conveyed at a fixed height, by means of a traveling support on monorail 25, to a pouring position on monorail 17. The height of the ladle when supported from the monorail 17 is fixed so as to insure the 105 pouring of all molds with the ladle at the proper distance above the molds and the lengthbf the monorail 17 .permits of the pouring being at such a point that fthe'ca'sting Will be at the proper temperature for removal from the mold When the movement of the'table 1 brings the mold beneath'the monorail29.- With the mold in position 'beneath the monorail 29, the cope and chill are removed by means of a hoist on the mono:l

rail 29 and placed on the joltin'g"inachiiie',`

the casting is cleaned byel power/driven,

brush supported from the crane 30and then placed by the crane 31 upon a gravity conveyor 32 upon which it travels to thesoaking pits. Ahub core reamer 33 removesrthecore A.. from the hub Whilethe casting. rests upon theV conveyor 32. The drag is removed fromthe.

@able 1 to a jolting `machine ZI-from Which it is'removed, by means of a hoist on'fthe monorail 3 4, to the gravity conveyors 10,*Where it cools as it moves toward themonorail 12,

Where itis again picked up for furtherjuse.

The sand deposited in thepit 8 is conveyed by means of belt conveyors, and an elevator 75 to a main storage bin carried on thev foundations 76 froml which it is conveyed by other conveyors and elevators to the supply' bin carried on the foundations 5, the sand being tempered and conditioned while being moved. Foundations 7 7 and 78 carry partof the overheadstructure of the elevators and conveyors-but as the sand conveying apparatus forms no part of our invention 1t 1s not shown in detail.

The traveling table 1 comprises spaced

circular channel members

35 and 36 connected at regular intervals by girder members 37 that are secured to the

channel members

35 and 36 by angles 38 and gusset plates 39, additional reenforcing members 40, and a top consisting of a plurality of metal sections 41 bolted to the

channel members

35 and 36. Secured to the undersides of the girder members 37 are supporting rails 42 that travel on Wheels 43 journaled on axles 44. The axles 44 are supported in bearings 45 mounted on bearing bases 46 on a suitable foundation 47 that is in the form of a pit so as to bring the table top at the proper height above the floor level. To the undersides of the girder members 37, and between the supporting rails 42 is a member 48, substantially H-shape in cross-section, that has one leg formed into a rack 49 engaged by a drive pinion 50 and the other leg forming a guide 51l that engages guide rollers 52 carried by roller bases 53 secured on the bearings 45, the legs being 1,605,442 BEST AyAll-ABLE provided with flanges by which the member 48, is secured to the girder members 37. Blates 54, supported 4'ateach sidefof the pit by angles 55 secured to the foundation by bolts 56, are connected by angles 57 and serve to keep the pit'clear.' Secured to the outer faces of the

channel members

35 and 36 areA platesv 58 which -projectbelow the

channel members

35 and 36 and overlap the Vupper edges of the plates 54 and keep material from droppingfrom the table into the pit.

To operate the table there are provided a plurality of driving 'units 59 which are placed in a pit beneath the controland pouring platform 60. vThese units are identical except that they are designed to operate the table at different rates of speed. The units are, therefore, adapted .to serve as spare or emergency units foreach -other and, with the range for the pouring and opening points given by the monorails 17 and 29they provide means for moving'the molds from pouring point to Vopening point in the proper time forA castings differing greatly in Weight. Each unit 59 comprises an electric motor 61 'controlled 4from a :controller box 62 on the platform 60Fand connected by a coupling 63 to shaft'64l of a Weighted y-Wheel or kinetic energy device 65, the shaft 64 beingconnected at its opposite endto the sha-ft'of a spur gear speed transformer 66. The shaft of the spur gear speedtransformer 66 is connected through a reversin -clutch 67 controlled by a lever 68 from t e control platform 60. The Vclutch* 67 operates a Worm Which, in turn, operates a Worm Wheel yin the casing 69. The Worm Wheel operates a shaft 70 which is connected through a coupling 71 to a shaft 72 which operates a pair of bevel gears in the casing 73. The bevel gears in the casing 73 drive the vertical shaft 74 upon which the driving pinion 50 is secured. The parts of the coupling 71 are adapted to be disconnected so that only the drive pinion and bevel gears of the spare or idle set Will be operated during the operation of the table. lVhile We have shown the drive units mounted upon integral bases, the various elements of the drive units may be mounted upon separate bases or grouped upon a plurality of bases as desired.
