' J12, a citizen of the llnited States, residing.

following is a specification.

in Philadel' hia, Pennsylvania, have invent: ed: certain provements in .Me l-Pouring Apparatus fo'rjGastin'g Plants, '0

M inventionirelates to certain the metal used in casting.

: he' vention isparticularly'adaptedfor rial stood that it can be use in other apparatus especially those'in which the flask is carrie by an intermittently movable conveyer.

w The object of my invention is to so conj struct the.,pouring ladle and the Carrying ladle thata'lar e-qua'ntity-of the molten. y and accurately handled, and the molten metal in the pouring ladle' kept at the proper temperature during the metal can be'qui P ns Pl The invention also relates to certain imrovements means whereby the pouring adle can' be readily removed when repairs are needed and another ladle quickly substituted for it.

In the accompanying drawings :Figure 1, is a-view showing my improved pouring ladle .with the carrying ladle located directly above itand in position to dischargethe wheelsbeing on one side and mounted in bearings on brackets 3, while the other wheel is mounted at the center on the other side.

.F our wheels may be used, if desir 4, 4 are the tracks upon which the Wheels are mounted and u on which the pouring ladle can be moved om its position to one Specification of Letters Patent.

'which the improvements' in the means for'carrying and'pour- 10' the 1ilghth dayj of January, 1910, under Se- 0. 587,076, 'althou h it-will be underpouring hole stead.

The pouringladlejis made, in the present instance, of an inner crucible 5'and an "outer shell '6. "There is' ,a space I between the crucible' and the shell 50' as to allow for products of combustiomfrom'aflgas 'or'oil urner to play around the crucible to kee' it hot. In the i resenfiins'tance the shell is another pouring ladle can" placed in its made ofa meta lie casing 8 a tire clay lin-- use in connection-with the continuous casting apparatus such-as shown and described 2 in the application'fo'r patent filed bylmeon 5 ing 9 and an asbestos fillin 10.

11 is the cover of the la le, also havin a metallic casing 12, cliigi'lining l3 and a lling of asbestos 14; yes 15 are secured to Patented A1ig.i6, 1912. A ucaumi med-m s, 19 10. Serial Nana-114.

I side, in the event of'its beingminjured so that the cover so that a crane hook can be readily V n the cover off the ladle.

i coupled to the eyes for thepu'rpose of liftxtendin'g through the'cover of the ladle is a sto V 'r 16, which-seatsiitself against a nipple 1 in the bottom-40f the crucible. 5, and in'the casting directlynnderthis nipple is an openingjls. the stopper is raisedthe metal will 'freelysflow through the nipple andthr'ough.the opening 1,8.into the 19 of. the mold. 20, which is located directly under the-ladlel L The stopper isjreducd at upper end and passes] throngh a fctoss'l'hea-d 2L On each end of this cross'headiare depending arms 22, which pass through guide s 23vin the shell 6 and have pins24'wh1cli are swiveled on a yoke frame 25 ivoted at 26. This yoke frame has ahand e 27 'by which the valvecan be 0 rated: r

A spring 281s mounted between a head on the stopper and-'the'cross head, so that,-1n the event of the stopper sticking'in the bottom, a pressure can be exerted which will first compress the springand then lift the .sto per.

e stopper is preferably provided with a projection '29 which enters a nipple 17 so as to'insure'the vstopp'er properly seating itself against the nipple. Y

In the' cover 11 is an opening 30 through which the crucible can evsupplied with molten metal this opening is directly above the crucible and the carrying ladle 3l' can be moved to" o'sition directly over the opening 30, as in 'cated in Fig. 1. The valve of this carrying ladle can be actuated so as to V allowthe molten metal :to. discharge from the carry g 'ladle' through the opening directly in the crucible 5. i f v The stopper of the carrying ladle, may be actuated by;any..suitable mechanism but I have shown in the .drawin mec anis'm similar to the operating mec anism of the stopper of the pouring ladle. 33 is a cap for closing the opening 30, and this cap is adapted to slide on ways34 and is actuated by a treadle 35 on a fixed floor 36 of the building. Pivoted to the cover 11' is a lever 37,-and' one-arm-of this lever is connected to the cap by a link'3'8, while the other arm of the lever enters a jaw 39, when in the position, illustrated in Fig. 3, of a weighted arm 40 which is ivoted on a shaft 41. On one end of this s aft is an arm 42 directly under .the tappet 43 and on the other end of the shaft 41 is a weighted lever 44, so as to normally hold the ea in its closed position, as illustrated in ull lines, Fig. 3. When theyfoot is placed upon the tappet 43 the cap is moved over to the position shown by dotted linesin'Fig. 3. By this construction the ladle can be moved away from the floor and placed back in position, or a new ladle placed in osition, and one arm of the lever 37 will a ine with the jaw 39 of the arm 40.

When the ladle is used in connection with a continuous casting apparatus, where the flasks are connected together in an endless chain, I mount the rails 4 upon ties 45, as

shown in Fig. 2, and these ties are slotted at 46, in the present instance, and pins 47 project through the slots from base plates and attached to the frame, consisting of the rails 4 and ties 45, is a screw 48 and on the screw is a handled nut 49 confined between bearings 50, so that on turning the handled nut the pouring opening in the ladle can be adjusted so as to aline positively with the pouring opening in the molds, as in molding machines of the continuous t pe theflasks may difler in size and this di erence in size will throw'the pouring opening to one side or the other, but by having the rails adjustable, as shown, the outlet opening in the ladle can always be brought into line with the pouring opening.

The carrying ladle 31 in the present instance is hung by rods 51 from a trolley 52 having wheels 53 which are adapted to an overhead track 54, and this track leads from the cupola furnace to a point above the pouring ladle and, in plants where there are a number of pouring ladles, the track extends over all of these ladles so that one carr ing ladle can supply molten metal to all 0 the pouring ladles.

In order to bring the carrying ladle uickly in alinement with the opening 30 of t e pouring ladle, I provide a stop 55 on the rail against which comes in contact a pin 56 on-alever 57 pivoted at- 58 to the trolley so that when the pin is in contact with the stop 55 the mouth of the pouringladle is in line with? the opening in the carrying ladle. i i.

In. order to prevent the, ladle swaying while being carried, I provide angle clips 59 which rest back of the rail, as shown in Fig. 4, so that while the ladle can be moved rapidly from one point to another it cannot sway and cause the ladle to spill.

In order to keep the molten metal in the pourin ladle hot, I provide a burner 60 which. IS COIIDGCtGd toa gas or oil pipe 61 and an air supply pipe 62, 'and a valve 63 is provided for regulating the flow of gas through the burner. When the gas is ignited the flame and productsof combustion will play over and around the crucible.

It will thus be seen thatI provide an apparatus for pouring molten metal especially adapted for continuous'casting machines, in which the carrying ladle can be brought quickly and accurately in line with the pouring ladle so as to discharge its contents into the pouring ladle, and that this single carrying machine can feed any number of pouring ladles, and that the metal in the pouring ladle is kept in a heated condition by the flow of products of combustion around the crucible.

The stopper can be uickly and mom rately operated so as to discharge any quantity of metal desired into the pouring opening of the flask.

In Fig. 6, I have illustrated a modification of my invention applied to a tilting ladle. 1' is a pouring ladle provided with a cover 11, having a central opening 30, which is closed by a cap 33. The spout of the crucible 5 extends through an opening in the casing of the ladle, as'shown.

I claim:

1. The combination of a pouring ladle having a casing, a crucible within the casing, a channel for products of combustion surrounding the crucible, the crucible having a pourlng opening, a casing'havmg an opening alining with the pouring openin in the crucible, a plug arranged to close said pouring opening, and means for supplying heat to the ladle.

2. The combination of a ouring ladle, a crucible within the ladle, said crucible having a pouring opening, a stopper for the said opening, a cover secured to the ladle, said cover havin an opening directl above the opening for t e introduction of t e molten metal, a sliding cap for the said opening, a two-armed lever having one arm connected to the cap, and operating means connected to the other arm for opening and closing the 0 318.

3. e combination of a pouring ladle havlng wheels; a track for said wheels, 9.

' movement of the ladle on the track, the lever can be moved into or outof the jaw.

4. The combination ofa pouring ladle having a cover,,sa1d cover having an opening, a sliding cap for the opening, a lever pivoted to the cover and having one arm connected to the cap, a shaft, an arm on the shaft connected to the other arm of the lever, a weighted arm, a tappet arm on the shaft, and a tappet in line with the arm so or moving the cap to its open or that when the tappet is depressed the cap will be opened.

5. The combination of a pouring ladle, a frame carrying the pouring ladle, a flask 20 under the ladle, and means for adjusting the pouring ladle and its flame so as to bring the pouring opening of the ladle in line wlth the pouring opening of the flask.

In testimony whereof, I have signed my 25 name to this specification, in the presence of two subscribing witnesses.
