WITNESSES M m 6 a ATT IVEY Be it-known that I, GEORGE K HOOPER, a citizen 40f -,th e ;=Unite d States, residing at Madison,- -.in the icounty o'fvMorris and State .5 ofNew: Jersey,'-have invented new anduseful "Improvements in Duplex Spouts for Furnaces, ofwhich fication. 1

invention relates to a reversible trough for drawing molterrmetal rapidly and continuously-,from-the furnace without loss, or damage tothe mechanism. v ,.In 3the;usua l;method of drawing molten metal from the furnace in which it is melted in. quantities greater than ladles carried by hand .-.can contain, 'it is customary to place the ladles by means of cars, or overhead handling, appliances, under the end of-the spout of the furnace when no metal is flow ing therefrom, and then by suitable means to cause the molten. metal to flow down the spout into the ladle until the latter is full when the flow is stopped, the firstladle removed and a second ladle substituted. The

the fiuidmetal continuously and it has been soughttofgain this end by means of movable spoutswhich could be moved to direct the stream of molten metal away from a .filled ladle .to an adjacent empty one. Movable spouts operating or swinging in a horizontal plane have been tried, but these'are defective'because in moving from one ladle to another much molten metal is spilled, in volvinga loss, as well as the annoyance of having the metal often, lodge in t11e mechan'ismby which the larger ladles are operated,

thusinterfering seriously with their opena-, tion and damaging them, sometimes to the 40 extent of rendering them; useless.

temperature and: chemical V compositionjanei ma) FF 4mm WPBRLQF mmsoamwasm Specification of Iietters latent the following is a specidesirability has been recognized of drawing It has become the modern practice, espe: cially in melting. iron for making malle-' metal from them by more than one spout; thevmost important reason for this is that it isfessentialto remove all of the molten e I metal as rapidly as possible, when the proper attained, to avoid both a loss in-burning, through over-heating, and also to avoidka change in chemical composition. Alsoin operating plants in which such large-fur names are used, it fis "desirable to havez3-th ladles accurately spaced to conform 'with the spacing of the spouts, that these ladles may. be removed and replaced by. one carrying apparatus.

My invention comprises ameans for facilitating' the above operations and vpreventing the losses above mentioned, permitting how ever the usual method of stopping andtapping the furnaces of whatever. formf they may be:

It is particularly supplementary device between the furnacej 1 and the ladle, so that-when one'ladle isfilled, the trough may be shifted instantaneously without spilling any metal to deliver into a second ladle, while the first is being removed.

My invention will be understood by" reference'to the drawing herewith in which the reference numerals 'of" this description indicate the corresponding parts in all the figures. p I 1 Figures l, 2and '3 are respectively a side elevatiompla-n and an end elevation showing my invention embodied" in afpairgoff, double nosed reversible or-shifting trou'ghs,

arranged and connected. to be operated simultaneously, 1n connection with two adj-acenttapping spouts on one furnace. A

smgle'troughcould' beused with ais in gle' spout,':or more than two; troughs simnltw.

neously, but the latter arrangeme'utc-lwould be seldomdesirable.

First to describe the mechanism offeacli trough .and then the-means bylwh'ich two on" more are'connectedytofbe operated together! In the figures, lxin'dicates the spout, from the cupola C, or other furnace, to conduct etalintotheladleswA-or" B. on lone-side or; I ;the qther;;1 As will be'sefen the deliveryends Y of ladles already referred to.

of each trough the arranged at such an angle to eachother that when one is'de about 110 to 120 is desirable.

6 is a shield on the side of the trough opposite the spout end to prevent any possible splashing-over of metal.

One of the trunnions or axles is provided with a crank 7, and where two or more tiltfiig troughs are arranged adjacent, the

cranks are connected together and to a motor 8"or other source of power by connecting rods 9, whereby all the troughs may be shifted simultaneously.

By my special form of tilting trough or spoutconstructed as shown and adapted to be arranged in two positions and to be quickly and positively shifted from one posltion to the other, when the ladle is ful I amenabled to withdraw the molten metal very quickly from the reverberatory or other furnace when it has. reached the proper temperature, so as not to expose'it too long to the heat with danger of burning. When ladle A is filled, the trough or series of troughs are quickly tilted to deliver into ladle B while ladle A is being removed and em'ptiedand brought back for -re-filling. Thus, the furnace may beemptied entirely or partially so far as may be desirable without interruption and very fast. Such rapid handling is effected without any spill or drip. I The shifting of the trough to deliver into ladle B and the removal of the first filled ladle by an overhead carrier is indicated by dotted lines in Fig. 1. I

aces. i Having described my invention, I claim,

'1. In a mechanism for delivering molten metal from a furnace to the ladle, the combination with a suitable standard, of a.

double nosed delivery trough journaled in the standard, said trough consisting of two delivery ends oppositely extending in the same vertical plane and arranged at an angle of not more than about 140 and more than 90 to each other and of means to rock the trough from one to the other of two positions,-whereby one end of the trough is in" clined downwardly to deliver all. the metal and the other end is inclfnr-sd upwardly. at a an angle of wardly to prevent the flow of the metal, said trough being formed on its central front portion to provide a shield for the metal entering from the rear and a stop bar rest secured on the standard forwardly of the baffle, and means to rock the trough.

3. In an apparatus for the delivery of molten metal from furnaces, the combination with a furnace having a plurality of outlets, of a plurality of suitable standards set adjacent to the respective outlets, delivery troughs journaled on the standards, said troughs each being provided with delivery ends oppositely extended and having continuous sidewalls on the sides to prevent the escape of the metal except through the ends, said troughs being arranged at such an angle to each other that when one end. is in the first position inclined downwardly the other end will be inclined upwardly to prevent the a metal flowing out from the opposite side, cranks on the trough journals, and a connection between said cranks to communicate the tilting of one trough to the other. I

4. A rocking trough mechanism for delivering molten metal from a furnace to oppositely arranged ladles, comprising a suitable standard, a delivery trough journaled thereon and having delivery ends oppositely extending and arranged at such an angle to each other that when one end is inclined downwardly to delivery the metal from said end the other end will be inclined upwardly to prevent the flow ofthe metal from said second end, means disconnected from the trough to deliver the molten metal into the trough from one side and a shield onthe trough on the opposite side to prevent splashing over of the metal being delivered to the trough.

5. A rocking trough mechanism for delivering molten metal from a furnace to oppositely arranged ladles, comprising a suitable standard, a delivery trough journaled there on and having delivery ends. oppositely extending-and arranged at such an angle to each other that, when one end is inclined downwardly to deliver the metal from said end, the other end will be inclined upwardly to prevent the flow of the metal from said second end, said trough being provided with practically parallel, continuous sidewalls extending unbroken from end to end to pretestimony whereof I have signed my vent the escape of metal except through the name to this specificatlon in the presence of ends, and v a spout disconnected from the two subscribing witnesses.
