WITNESSES X [NYE/17?? may " Enema. ousrnn, or PHlLADELPHIA, P NNSYLVANIA.-

' m mps non normme AND rdauam am mt".- Be it known that I, EDGAR A. Cus'rnn, a citizen of v the United 'States, residing in the city of -Philad elphia; in the c'ounty of Philadelphia and State of Pennsyl;

Vania, have invented certain new and useful improvements in Apparatus for Holding and Pouring Metal'in to Molds for (lasting Operations, of which the following is aspecification. i I

My invention has relation to an apparatus for holding and pouring molten metal into molds for casting operations; and in such connection it relates more particularly .toladles containing the molten metal and means I "for supporting and tilting the ladles.

.The principal obiects of my invention are first,

or spouts, during the tilting to discharge the molten metaltherefrom is or are held and maintained at substantially fixed position with respect to a mold; second, to so support the ladles that the same are held with their spouts in the same horizontal plane, and thus at a uniform height above'a mold located beneath the ladles; third, to provide ladles with substantially the same shaped outlet spouts to insure discharge of equal quantities of molten metal therefrom, and fourth, to provide means for supporting and uniformly tilting the ladles during the discharge of the molten metal therefrom.

' The nature and scope of my invention will be more 7 fully understood from the following'description taken in connection with the accompanying drawings forming part hereof, in which,

Figure 1, is a 'vie'w illustrating in top or plan, a movable trnck, bearings for shafts carrying supports for two sets of oppositely arranged ladles mounted thereon, and

forming thecontinuations of the shafts, means for positively actuating oneof the divided shafts, and means for transmitting the movements of one shaft to-the other, all embodying main featuresof my said invention. Fig. 2 is a view, illustrating partly in lo'ngitudi- 40 ml section and partly in elevation, the truck and one of the series of ladles supported by the same; and Fig. 3 is a 'view enlarged, illustrating partly in cross-section and partly in elevation, the truck, the support for the ladles andthe ladles in a tilted position for pouring molten metal into a mold placed beneath the truck.

7. way, not shown, or may be minus such flanges to permit of the shifting of the truck to any place desired. Upon theplatform 4, are arranged bearings 9, supporting respectively, shaft sections 11, over an opening 10, in the platform, which sections in the present instance, are

united to each other by supports 12, each having a subof Letters Patent. V Application mad 1 m 26. 1901. Serial No. 370.444.

stantially semi-circular v depression l3, e'xtending be- 'yond the central longitudinal axis of the shaft-sections 11, held in alinement to each by the supports 2. Each of the supports 12, is provided 'witha ring-shaped extension'14", serving as a seat for a ladle 15. As shown in Figs. 1 and 2, the ladles 15, rest uponthe platform 4, and

are held by'the bearings 9, shaft-sections 11, and supports 12, in staggered relationship with respect to each other, and with their discharge spo'lutslfi, over the depressions 13, in such a position as that their supports 12, terminate in the longitudinal iceneia axis of the shaft sections 11. It must be-borne mind, however, that the sectional shafts 11, supports 1:2,ai1d their extensions 14, may be replaced by a single or solid shaft so shaped as to form the necessary seats for ladles 15, while at the same time so arranged as not to obstruct the discharge spouts lfi, thereof.

One of the sectional shafts'llgisprovided; with a handcrank 17, adapted to permit iof the manual rotation of the shaft 11, carrying the crank and thus of a tilting of the sets of ladies 15, supported by such shaft.

In order to insure the uniform tilting of both sets of remiss-mass, r907.

to the shaft 11, carrying the second set of ladles 15.

Thus the movement of one shaft 11, is transmitted to the other of the shafts 11, and both sets of ladles are tilted at exactly the same time, and with exactly the same speed, As the spouts 16, of eachofthe two sets of ladles 15, terminate in the longitudinal central axis of the shafts 11, it follows, that during the tilting and over which the truck 7, has been shifted, so as to bring the pour-holes 23, of the cope 21, thereof, directly below the discharge spouts 16, of the ladles l5. As the spouts 16, of the ladles are of substantially the same size, equal quantities of molten metal will be discharged from the same, due to the-maintenance of the spouts velocities. The molten metal entering the pour-holes 23, of the cope 21, of the mold will thus reach the depressions 24, forming the mold proper, in the cope 21, and drag 22, under the same pressures and velocities and the flow of each portion of themolten metal in the depressions 24,,will be uniform, thereby insuring a casting of 'anarticle perfect in outline and shape. To impart a smooth surface to the article cast, the

mold is preferably formed of a permanent unyielding material, such as metal, which is adapted to retain in a fixed position with respect to the mold 20, and

such discharges will be at thesame pressures and heat absorhed from the molten metal and which heat thereby aids in the formation of a perfect pipe having a smooth-external surface. To form a. harbor-for the Y gases, the cope 21, is provided with a channel 25, while 'as long as. their spouts 16, are of uniform size,-and terminate and are maintained during the tilting thereof insubstantiallya fixed position and at the same horizontal plane, with respect tothe pour-holes 23, of the mold 26. Moreover, the ladies 15, may be arranged? in a single row and caused to assume asta'ggeredposition in respect to each other, if desired.

Having thus described the nature and objects of my invention, what I claim as new and .desire to secure by Letters Patent is:-- I

1. The combination, in an apparatus for pouring'molten metal, of a mold. a ladle adapted to contain molten metal having a spout and means for supporting the ladle so as to hold and maintain said spout in substantially a fixed position with respect to said mold and with the pouring point for the metal at about the point of support otsaid ladle.

2. The combination, in an apparatus for pouring molten metal, of a mold, ladies adaptedto contain molten metal having discharge spouts, and means for supporting said ladiesand holding the'spouts in the same horizontal plane amass holding and actuating said support to maintain the spout of such ladle in substantially a fixed position with respect to said mold at and during the discharge oi! the metal therefrom.

4. The combination in an apparatus tor-pouring molten metal, of a mold, two series oi ladies, each having a spout, means for supporting each of said ladies so that the spouts thereof at and, during discharge of the metal are held in substantially a fixed position with respect to said mold.

5. in an apparatus of the character described, a movable truck, bearings supported thereby, shafts and supports carrled by said bearings, ladies each having a spout, said ladies adapted to receive molten metal carried by said supports and held with their spouts in the longitudinal central EDGAR A.
