ZINNO, OF WATERBURY, CONNECTICUT, ASSIGNOR TO THE CHA SE COM- PANIES, INCORPORATED, OF WATERBURY, CONNECTICUT, A CORPORATION APPARATUS FOR POURING MOLTEN METAL Application filed December 30, 1929. Serial No. 417,333.

This invention relates to an improvement in apparatus for pouring molten metal or other molten material and particularly to an apparatus for pouring molten metal into flasks or molds in connection with casting operations, though not so limited.

Heretofore, it has been the practice when pouring molten material into flasks or molds to carry the said material to the molds or flasks from a furnace or other large storagecontainer by means of portable hand-manipulated ladles in order to effectively and properly control the flow of material as it is delivered into such molds or flasks.

The above procedure has been laborious, wasteful and otherwise ineflicient for many reasons, among which may be mentioned the cooling of the molten material before it could be poured into the flasks or molds, thereby necessitating an excessively-high initial temperature, with the result that oxidation was increased, the molds oftentimes eroded, or the material cooled to such a degree as to imperfectly spread in the mold.

The main object of this invention is to provide a convenient and reliable apparatus of the type referred to constructed with particular reference to conveniently and effectively controlling the flow of molten metal, etc., from a large container, such as a meltingfurnace or other relatively large container, into smaller containers, such as flasks or molds.

With the above and other objects in view as will become apparent fromthe following, my invention consists in an apparatus for pouring molten metal, etc., characterized by the employment of a delivery-container mounted in a plane below the spout or discharge-opening of a relatively-large storagecontainer with capacity for independent tilting movement with respect thereto and positioned intermediate the said dischargeopening and the flasks, molds, or other receiving-containers, into which it is desired to pour the contents of the storage-container, so that the molten material is delivered from the storage-container to the receiving-containers through the intermediary of the said 50 tilting delivery-container, whereby the flow of molten material from the storage-contamer into the receiving-container may be readily and conveniently controlled.

My invention further consists in an apparatus for pouring molten metal, etc., charactermed as above and having certain other details of construction and combinations of parts as will be hereinafter described and particularly recited in the claims.

- In the accompanying drawings:

Fig. 1 is a top or plan view of an apparatus for pouring molten metal, etc., shown in conunction with a melting-furnace;

Fig. 2 is a view thereof in front elevation;

Fig. 3 is a view thereof in side elevation;

Fig. 5 is a broken, vertical, sectional view taken on the line 55 of Fig. 2, but on a larger scale; and

Fig. 6 is a vertical sectional view taken on the line 6-6 of Fig. 5, but on a larger scale.

In the embodiment herein chosen for the il lustration of my invention I employ a ladleshaped container 10 which I shall for convenience of description hereinafter refer to as a delivery-container and which is provided 0 with a lining 11 of refractorymaterial and fernlinates at its forward endin a pouringip The said delivery-container is mounted for tilting movement in a plane below-and preferably with its inner portion directly beneaththe spout 13 of a tiltable meltingfuriiace 14 or other relatively-large storagecontainer by providing it on its respective opposite sides, near the upper edge thereof, with outwardly-projecting

bosses

15 and 16, respectively receiving trunnion-studs 17 and 18 projecting therein respectively from the upper ends of the complementary

curved arms

19 and 20 of a mounting-yoke 21, which 5 latter is enlarged at its central portion as at 22 for the purpose as will hereinafter appear.

It will be noted from the drawings and particularly in Fig. 5 thereof that the delivery- 100 container 10 is so mounted that its inner and most capacious portionlies to the rear of the trunnion-studs 17 and 18, so that when charged with molten material there will be no tendency for it to ti forward b gravity.

For the purpose of ti ting the sai deliverycontainer as required to cause its contents to flow into a mold or flask 23,1 rovide the said container with a fork-shape hand- 10 and comprismg a pair of complementary L-

shaped arms

25 and 26 inclined slightly forward as shown and respectively perforated as at 27 and 28 for the reception of the bosses and 16 and secured at their lower ends by means of rivets 29 to the opposite side-faces of the said delivery-container. The upper ends of the L-shaped arms and 26 just; referred to are united as shown and terminate in' an upstanding handle 30.

To provide for bodily moving the deliverycontamer 10 radially a limited distance toward and away from the melting-furnace 14 and to provide for swinging the said container laterally for the purpose as will hereinafter appear, I pass downward through the central portion 22 of the yoke 21 a stud 31 upon which the said yoke 15 free to turn and which has its lower end threaded into a reciprocating carriage 32 mounted in the horizontal arm of an L-shaped bracket 33 to which it is secured by

plates

34 and 35. The said bracket 33 is secured to the central portion of a cross-bar 35 secured at its respective opposite ends to

standards

50 and 51.

The stud 31 is mainly designed to position the yoke 21 upon the carriage 32 with capacity for horizontal swinging movement but the load is intended to be mainly taken by an anti-friction bearing comprising an upper-race 36 hearing against the underside of the central portion 22 of the yoke 21, and a bottom-race 37 located in an annular recess 38 in the said reciprocating carriage. The said races have interposed between them a series of balls 39 in the usualmanner of antifriction bearings.

Secured in a longitudinal groove 40 in the underface of the carriage 32 is a rack-bar 41, the teeth of which are meshed into by the teeth of a pinion 42 mounted upon the inner end of a horizontal laterall -extending shaft 43 hearing of the bracket 33 and having an upstanding hand-lever 45 secured-to its outer end.

It will be seen from the foregoing that the delivery-container 10 is mounted for vertical tilting, lateral swinging, and bodily rectilinear movement, toward and, away from the melting-'furnace-14, which latter is, as shown, of the tilting type, being provided near its respective op osite sides with forwardly-extending brac et-

arms

46 and 47 respectively provided with heavy studs 48 and e5 49 respectively bearing in the upper ends of lever generally designated by the numeral 24 in a boss 44 in t e horizontal arm.

standards

50 and 51 upstanding from the foundation 52 on opposite sides of the furnace, as clearly shown in Figs. land 2 of the drawings.

As shown, though forming no part of my present invention, the flasks or molds 23 are preferably mounted upon carriages 53 provided with flanged wheels 56 riding upon rails (Figs. 3 and 4) so that successive flasks may be presented beneath the pouringlip 12 of the delivery-container 10 in rapid succession.

Coming now to the operation of my improved pouring apparatus, let it be supposed that a flask or mold 23 has been positioned beneath the pouring-lip 12 of the deliverycontainer 10. The melting-furnace 14 will be tilted forward in the usual manner ofsuch furnaces to cause the molten metal therein to flow outward through the spout 13 and into the delivery-container 10 preferably in a steady stream. The said delivery-container will now be rocked by means of the handle 30 to depress its pouring-lip 12 and permit the molten metal. to flow into the flasks 23 preferably as rapidly as the metal is received by the said container.

When any given flask has been fully charged with molten metal, the delivery-container is returned to its normal position until another flask has been positioned beneath its pouring-lip, meanwhile continuing to receive and store the metal pouring from the spout 13 of the melting-furnace. When the newlypresented flask is in position, the deliverycontainer will be again tilted forward and downward to pour its contents into the flask in question, together with the molten metal which continues to flow into it from the furnace or other relatively-large container.

The delivery-container 10 as before stated may be swung laterally also by means of the handle 30 to align its pouring-lip'with the various openings in a flask such as 23. In the event that the pouring-lip of the container 10 projects ins ufliciently or excessively so as not to align itself with the openings in the flasks as they are presented, the said container may be bodily moved in and out with respect to both the furnace 14 and the flask 23 by means of the hand-lever 45 acting through the pinion 42 and rack 41.

It will thus be seen from the foregoing that by means of my invention- I have provided a convenient. reliable and effective apparatus for controlling the flow of molten material from the furnace 14 or other relatively-large container into receiving-containers, such as the flasks 23, with a minimum loss of time, effort, etc., since the deliverycontainer 10 acts as an intermediate storagecontainer and provides for the intermittent delivery of molten material into the receiving-containers while permitting the storagecontiainer to discharge continuously if desire It will also be understood that it is not necessary that my improved apparatus be used in connection with a melting-furnace,

since it is often desired to deliver molten material from storage-containers which are not in themselves melting-furnaces.
