Referring to the drawing in detail it will be seen that the numeral 5 denotes Ia car platform mounted on wheels 6 adapted to ride on rails l. The platform is provided with an oblong opening 8 with an annular ball bearing race 9 disposed thereabout. Numeral I denotes a mold base the bottom of which is provided with an yannular race il of such a size to register with the race 9 and from the center of the bottom projects a pintle I2 with oppositely ldisposed ribs I4. The pintle with its ribs extends into the oblong opening. Ball bearings l are mounted in the races 9 and Il. Thus the base may oscillate on the platform 5 and is limited by the abutment of the ribs i4 iof the opening 8 ias vis b'e'st illustrated -re V6'. The yi;1atfflni is provided with a Eve Il'fl.

Cables 40 may be engaged by eye bolts 4I with the connecting rods and extended over suitably mounted pulleys 4| and weights 42 may be mounted on the ends of the cables to hold the connecting rods in a raised out ofthe way position when desired.
Numeral 43 denotes the mold which at its bottom is provided on opposite sides with outwardly extending lugs 44 disposed between lugs 45 rising from the base I0 in pairs, one pair for each lug 44 and Wedge pins extend through openings in the lugs 45 over the lugs 44 thereby securing firmly the mold to the base.
When the machine is started, it oscillates the mold and the hot metal is poured into the mold. All the impurities are forced to the top and the machine is kept in motion until the metal is solid. in Figure 3 I have indicated the ingot formed in the mold 43. Numeral 46 denotes the ingot and numeral 41 indicates the defect at the top thereof.
It is thought that the construction, operation,
utility and advantages of this invention will now be clearly understood by those skilled in this art without a more detailed description thereof.
The present embodiment of the invention has been described in considerable detail merely for the purposes of exemplication since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description.
It will be apparent that changes in the detalls of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed or sacricing any of its advantages.-
Having thus described my invention, what I claim as new is:
1. A machine of the class described including. a platform, a. mold-carrying base mounted on the platform for oscillatiCn thereon, a shaft, a pair ofcams mounted on the shaft and disposed in opposite directions, connecting rods, rings on the connecting rod circumjacent the cams, said conrnecting rods having ends terminating in pins, and said base having eyes to receive said pins, a pulley, a cable trained over the pulley, a weight on one end of the cable, and means forl engaging the other end of the cable with one of the connecting rods.
2. In combination, track rails, a car movable on said track rails and including awheeled platform provided with an annular racein the upper surface thereof and having an elongated opening therein centrally'of the race, a mold carrying base having a second race in the bottom surface thereof and provided centrally of said second race with a depending pintley received. in said opening of the platform, lugs on the pintle coacting with walls of the opening to limit oscillation of the base about the vertical axisY of said pintle, ball bearings interposed between 'the platform and the mold base and disposed in said races, and oscillating means for the base including a connecting rod detachably connectedto the base and means for reciprocating said connecting rod mounted beside the track rails.
3. In combination, track rails, a car movabl on said track rails and including a wheeled platform, a mold-carrying base mounted on said platform for oscillation about its vertical axis, `and oscillating means for the base including a connecting rod detachably connected to the base and means for reciprocating said connecting rod mounted beside the track rails.
4. In combination, track rails, a car movable on said track rails and including a wheeled platform, a mold-carrying base mounted on said platform for oscillation about its vertical axis, and oscillating means for the base including a connecting rod detachably connected to the base and means for reciprocating said connecting rod mounted beside the track rails, said connecting rod being swingable upwardly when disconnected from the base, and yieldable means to hold the connecting rod in upwardly swung position.
r5. In combination, track rails, a car movable on said track rails and including a wheeled platform, a mold-carrying base mounted on said platform for oscillation about its vertical axis, and oscillating means for the base including a connecting rod detachably connected to the base and means for reciprocating said connecting rod mounted beside the track rails, and manually releasable means to prevent oscillation of the base relative to the platform. v
6. In combination, track rails, a car movable on said track rails and including a wheeled platform, a mold-carrying base mounted on said platform for oscillation about its vertical axis, and Oscillating means for the base including an extensible connecting rod detachably connected to the base and means for reciprocating said connecting rod mounted beside the track rails.
