L. HAYNES, OF BURLINGTON, JERSEY, ASSIGNOR 'IO UNITED STATES CAST IRON PIPE @a FOUNDRY COMPANY, A CORPORATION F NEW JERSEY.
CENTRIFUGAL CASTING APPARATUS.
Application led September i9, 1922. Serial No. 589,062.
To all whom t may con-cera:
Be it known that I, WILLIAM L HAYNES, a citizen of the United States of America,
and resident of Burlington, county of Bur-VV lington, State of New JerseyVhave invented certain new and useful Improvements in Centrifugal Casting Apparatus, of which the following is a true and exact description, reference being had to the accompanying 30 drawings, which foim a part thereof.
My invention vrelates to centrifugal cast! ing apparatus, in which the melted metal is introduced into the rotating mold through a trough and in which the mold and trough 515 are relatively retractable so that the trough can be fully entered in the mold or entirely retracted therefrom. More particularly, though not exclusively, my invention is intended for use in the de Lavaud type of apparatus in which the trough is used as a runner delivering melted metal from its open end while the mold is being retracted.
In centrifugal molding apparatus as heretofore constructed time is lost owing t0 the necessity of cleaning out the trough or runner between successive molding'operations and 'it is the obj ect of my invention to provide an improved apparatus which will provide for the cleaning of a used trough or a0 runner while the machine is in use and under more convenient conditions than has 'heretofore been the case.
- Generally speaking, my invention consists in providing in connection with a centrifut gal mold, longitudinally movable with 'rela'- tion to its feed trough, a transversely movable trough supporting carriage on which are secured two -parallel feed troughs spaced apart so that one can enter the mold and eo the other extend outside the mold and its su ports.
y invention will be bestunderstood as described in connection Awith'the drawings in whichl Figure 1 is a plan View of my improved molding apparatus, and f Figure 2 a sectional elevation on line 2-2 of Fig. l.
mdicates the framing supporting the .molding apparatus and A tracks orguide- .ways on which the casing enclosing and upporting the rotatable mold moves to and ro. and mold, B being a piston in said cylin- B is a cylinder for moving the casing der; B2 the piston rod and Ida the head b E, IE, are supporting guides secured to the framlng and running at right angles to the axis of the mold and F is a trough supporting carriage' transversely movable on said guides and supporting two troughs or runners, one indicated at G G and the other at g g. G2 and g2 indicate the open ends of the runner trough through which the metal enters the mold. The troughs are parallel to each other and spaced as shown so that one can enter the mold and the other extend alongside the casing.
I-I, H, arey supports for the supply ladle I which is pivotally supported on thetuds H H through its arms I', I' to one of which is secured a pin I2 to which is connected the piston rod J of a piston moving in cylinder J.
K is a cylinder for moving the carriage F through its piston rod K.
The dotted line P, Fig. 1, indicates a position of the left hand end of the mold and casing to which they must move to clear the ends of the runner trough.
In operation and with the illustrated apparatus, a trough or runner as Gr, is shifted ,with its carriage so that it' registers with the mold and with the ladle I. The mold is moved over the trough to the position shown and set in rotation and molten metal poured into the trough from the ladle and as the metal enters fthe mold through the open end G2 of the trough the mold is moved towards the right until it is fully charged with the casting and, after perhaps a rest, the mold is still further retracted until the end of the trough is entirely cleared. The casting is removed from the moldbut before pouring again the carriage F is moved until the trough g, g registers with the mold and ladle and while a new casting is being poured the trough Gr, Gr', can be conveniently cleaned preparatory to re-use. In this way the troughs are prepared for e-use without dela-ying the casting opera- Having now described my invention, what I claim as new and ,desire to secure by Letters Patent, is:
'1. In a centrifugal casting machine, a rotatable mold in combination with a trough supporting carriage movable in a plane transverse to the axis of the mold, two parallel troughs secured to said carriage at a distancefapart which 'will permit one trough to enter the Inold and the other to clear the mold supporting mechanism, and means for giving a relative longitudinal movement to the mold with reference to the troughs whereby the trough in registry with the mold can be fully inserted in or fully withdrawn from the mold.
2. In a centrifugal casting machine a lon# gitudinally movable rotatable mold in c0111- bination with a transversely movaible carriage a-nd tWo parallel troughs secured tol carriage spaced apart so that one trough can enter the mold and the other clear the mold supportsand a ladle for melted meta-l located to register with the trough in registry with the mold.
WILLIAM L. HAYNES.
