MULTIFLE TAPPING-SFGUT.

l. ping-Spouts, of which the following is a specification.

in the operation of furnaces,especiai1y those of the open-hearth type, it is necessary or desirable that when they are once tapped the iioiv of molten metal shall. continue uninteriniiteriijv'. in some cases, however, it isl desirable t ne ahie to switch the iiov iriiin one receiving receptacle to another "Without stopping or interrupting the discharge of molten nietai,'ai1d it is the provision of a ctevice of this character which forms the subject mattei' oi this invention, the leading aim and object of the latter heing the construction of a multiple tapping spout which xviii effectively aecompiish the desired. result, which may he easilyr operateii, and which iviii eon'iparatively@ economical to inannfaotuie.

an open-top trough having at its inner end a single admission' mouth 'and at its other end a pair of discharge mouths Between the furnace spout il and the bifurcated spout 14:, and adapted to convey the molten metal from the former to the latter, provide a curved connector 17 into one end of which the spout l1 delivers the metal, While the other open end of the same is adapted. to be shifted so as to convey the 'metal to either one ofthe pair ot'

dischargetroughs

15 and 16. In reality this connector 17 constitutes a curved hoiiovv pipe, the purpose ot which is 'to shift the delivery of molten metal from one discharge inout-h to other of the hiflneated tapping spout 1.4. At its outer enti, as indicated perhaps moet cieariy in Figs. 3 and 5, this connector 17 is supplied with a trunnion 18 itt-ing inZ a cylindrical hearing 19 provided on the upper end oi the yoke '13., which iorinsi the support for the two snouts -1- rThe hearing 19 has a cap 2t) anti a hiess oir other relaxt-ii eiy sott metal iining The other end of this lconnector, that is, the end into vwhich the spout ii p has on its outer surface a gear 2.2, anc. on opposite ies of theteeth of the saine a pair oie ey 2?; r'nd ifhis gear anti icings are covereff hy divide@ casing 25, the two s which are hoiteci t C. 1 er at '126 anc.v which early a ninnber ami-friction h hearings in the tivo siti of t ingi rihese rollers, as is dear-ty indici ceri .n Fig. 6, have two eniargeci c5' i portions 29 which heer on the parte anti- 24, 'the section oi? the roller between such eniargeoi portions being of reduced diameter so as to escape contact withithe gear This fear casing aiso {iii/'idool transverseiyy the upper and lower haives 'being joined through the tian'ges 25h, hy ineens of lthe boite A fitter each pouring operation, connector 17 Wiii retain on its inner surface a coatingr or i shizii of ste'ei and siag, eine to the eooi'- ing of the niet-ai as it pass'e through the eihow. in order to remove this 'simil to "e, the connector 1'? should he eihow l? may he easiiv iitteti out of piace i'etnined thereto when desired.

its associated parte to a more 1 Below the gear end of the connector and on suitable standards 30-30, a compressed air cylinder 31 is mounted, the same being provided with a piston or plunger, not shown because the same may be of the usual and ordinary construction. The cylinder has associated therewith the connecting pipes 32 for the admission and discharge of the compressed air, as is usual in a device of this kind. The reciprocatory piston of such cylinder is connected by a piston-rod 33 with a rack 34C, having a down turned end 35 for such connection and supplied with a plurality of teeth 36 meshing with those of the gear 22, it being understood, as is shown in Fig. 4, that the casing of the connector is cut away to permit the proper reciprocation of this rack.

The operation of this appliance is substantially as follows; 'Ihe compressed air is admitted to the cylinder or chamber 3l so as to force the unclosed piston or plunger to one end of its linut of travel, such movement of the plunger or piston causing a corresponding sliding of the rack 36, the movement of the latter rotating the gear 22 and the connector whereby to bring its outer mouth into direct communication with one or the other of the spouts l5 or 16. The furnace is then tapped and the Amolten metal flows down the spout ll through the connector 17 and through one of the spouts, such for example as 15,into a receptacle or ladle 37 placed beneath the same for the reception of the metal. lVhen the desired 0r proper amount of the liquid metal has been received by such ladle or the like, the supply of compressed air to the cylinder 3l is manipulated so. as to shift the piston or plunger to the opposite end of its travel,

lthereby through the rack and gear connection rotating the connector in its two roller bearings so as to establish communication between the spout l1 and the other mouth of the bifurcated trough. As will be readily understood, the metal now iows into the receptacle 88, and while so doing the ladle or other container 37 may he removed and another put in its place, so that when the receptacle 38 has received its proper quantity of metal the connector may be again shifted so as to establish the flow of metal` detailed construction of the parts which I have describcdwithout departing from the spirit of my invention.

I claim: f

l. In a device of the character described, the combination of a relatively stationary spout with a plurality of discharge mouths, a movable connector adapted to convey the molten metal from the furnacel to said spout, and means whereby said connector may be shifted to'have the metal issue from any one of the mouths of said spout without inter.- ruption of the llow, substantially as 4described.

2.
