Application filed April 19, 1904. Serial No. 203,936-

To (all 7071 0772 it may concern:

Be it known that I, CARMI L. GLovER, a citizen ofthe United States,residing at Newcastle, in the county of Lawrence and State of Pennsylvania, have invented certain new and useful Improvements in Molten-Metal Conductors for Cupolas, &c.; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of my invention is to obtain greater speed and economy in handling molten metal drawn from cupolas or other furnaces or vessels, and particularly to save time, labor, and crane service in conducting ofi the hot metal and pouring it into molds or other receptacles. This is accomplished by means of a pivotal conducting vessel located for receiving a continuous flow or outpour from the furnace or supply vessel, but adapted to be turned during such inflow so as to pour the hot metal from its discharge-spout into different molds orreceptacles without interrupting the flow from the main source of supply, means being also provided for tilting the conducting vessel, so as to raise its dischargespout as said vessel is turned to change the pouring from one receptacle to another for the purpose of avoiding waste, and the capacity of the conducting vessel being suflicient to prevent overflow during the periods of interruption of its discharge or pouring.

With the ordinary mode of operating cupolas and similar furnaces, especially in foundries, the molten iron or metal which collects at the bottom of the cupola or on the furnacehearth is drawn off through the tap-hole into receiving vessels, and when one vessel is filled the flow of the molten metal must be stopped until the full vessel is removed and an empty receptacle put in its place.

My present invention provides for the direct filling of a number of vessels, molds, or ladles one after another, without loss of time in removing and replacingthe full and empty vessels and without the necessity of stopping the continued flow of the molten metal from the cupola or other furnace, or from the direct metal ladle or main supply vessel.

1n the accompanying drawings, which are to be taken as a part of this specification, I have illustrated simple and eflicient apparatus embodying my invention in connection with an ordinary cupola-furnace, though it will be understood that the invention is not limited to this or any specific embodiment, and that the hot-metal-conducting apparatus is susceptible of various modifications in particulars of construction and arrangement and is adapted for use to receive and convey away the metal from different kinds of furnaces or vessels. Hence without restricting myself to the specific construction illustrated the invention will first be described with reference to said drawings and then more particularly pointed out in the claims following this description.

Figure 1 is a side elevation of the lower portion of a cupola-furnace and molten-metalconducting apparatus embodying my invention with an underground compartment for the slag-receiving pan represented in vertical section. molten-metal-conducting apparatus. Fig. 3 is a top plan view of the support for the pivotal base on which the conducting basin or vessel is mounted. Fig. 4: is a'front view of said conducting apparatus.

The numeral 1 denotes the cupola, 2 the slag-hole, and 3 the tap-hole. From the taphole at the bottom of the furnace is shown extending outward a discharge-spout 4L. The molten metal flowing from the tap-hole is discharged by the spout 4 into a conducting basin or vessel 5, having a laterally-projecting discharge spout or trough 6, which is preferably inclined downward toward its outer end, while the basin 5 rests normally hori- Zontal. This basin and its discharge-spout, like the discharge-spout from the furnace, are preferably lined inside with fire clay, brick, or other suitable refractory material. The basin or vessel 5 is supported by trunnions 7, the bearings of which are in standards or uprights 8, rising from a pivotal base 9. This base, which is usually of circular form, is supported on a suitable table, platform, or like support, here shown on a bracket 10, projecting from the operators stand. Said base 9 is preferably supported on rollers 11, arranged in a circle around the central pivot axle or journal 12 on the bottom of the base. It will thus be seen that the base, together with the basin or vessel 5 supported thereby, can be turned on its vertical axis, so that the Fig. 2 is a side view, enlarged, of the discharge end ,of the spout 6 can be made to describe an are or circle around such axis or central pivot 12. The weight of the trough or discharge-spout 6 tends to tilt that side of the basin on its trunnions; but the base 9 has an upstanding flange or projection l3, ;,Wl1lCl1 forms a rest for the said trough or spout, and

thus normally keeps the basin horizontal or practically so, in which position, however, the trough slopes downward to facilitate the discharge of molten metal therefrom. Fulcrumed to the flange or support 13 is a lever or levers 14:, by means of which the basin can be tilted to raise the discharge spout or trough. Two levers are shown, having long arms for manipulating them and short arms bearing up against the under side of the trough. By pressing down upon the long arm of either lever the trough will thus be raised to prevent the flow of molten metal therefrom.

In operation the diflerent vessels or receptacles for receiving the molten metal are arranged on the floor or ground within its are described by the outlet end of the discharge spout or trough 6. The molten metal is drawn from the cupola into the basin 5, from which it is poured into any one of the receiving vessels from the spout 6, and when one receptacle is filled the basin is turned to carry the spou t around over the next empty vessel. At the same time, if necessary, the outer end of the trough or spout can be raised by the tilting lever or levers 1st to stop the flow of the metal during movement of .the trough from one vessel to the next, but without any stoppage of the flow of metal into the basin. The basin is sufficiently large to hold all the metal flowing into it during the brief period while it is tilted to change from one vessel to another. As shown, the discharge spout or trough projects out from the vessel below its top and above its bottom, and the top of the vessel is inclined downwardly from the back toward the front or discharge end of the spout, which construction provides the requisite internal capacity of the vessel during the backward tilting thereof to interrupt the outpour.

For conducting the slag from the slag-hole I have provided an inclined slag-trough 15, which is shown having a central vertical pivot on a bracket 16, attached to one of the rear supporting-columns of the cupola. The slag when running from the cupola drops into this trough and runs down into a receiving pan or vessel 17, which is sufliciently large to hold one days run of the slag. Said receiving-pan is arranged on rollers 18, so that it can be pulled by a crane (not shown) through the medium of a chain or cable 19 and picked up by the crane and dumped into a car or other place for disposal of the slag. In this instance the receiving-pan is shown located in an underground compartment beside the cupola.

sometimes happens that there is difficulty in tapping and the molten metal continues to accumulate till it reaches the slag-hole and runs out at that point. By means of my pivoted slag-trough in case the molten metal runs out through the slag-hole the receiving end of the trough can be pushed away from the cu pola and allow the metal to drop into a receptacle placed for it. thus preventing loss of metal by allowing it to mix with the slag which has previously run from the cupola.

I claim as my invention and desire to secure by Letters Patent ot' the United States- 1.
