TRANSFER SPOUT.

To all whom t may concern.' i

Be it known that I, FRANK B. MCKUNE,

a citizen of the Dominion of Canada, re-

siding at Hamilton, in the Province of On-K 5 tario, in the DominionL of Canada, have invented certain new and useful Improvements in Transfer Spouts, 0f which the following is a specification.

This invention relates to the art of pouring metal in ingot molds by the cascade or continuous flow method disclosed in my ap- Briefly, in 'carryingout that method the molds are preferably arranged in stepped series. T e metal is poured into one mold continuous y until it overflows and fills, successively, all the remaining molds in the series.' In passing from one mold to the next mold the metal flows over the transfer spouts.

I have found, in practice, that with the use of small molds i. e. molds having small openings, the stream of molten metal flow# ing across the transfer s out from a pre ced ing to a succeeding mold) sometimes extends oyer the farther edge of the succeeding v mold, and in timedestroys the usefulness ofthe mold as well as causes the ingotto hang in the mold when the spilled or extended metal has solidified. .My present )invention therefor has'for its primary object to provide a transfer spout which will avoidthe objections stated fas well as to provide means for delivering he molten stream of metal from a preceding mold directly-downward into the succeeding mold instead of in a curved stream, thus simulat` ing the stream that flows from the ladle (or the distributing boX if such is used) Athereby effecting more uniformity in the lintroductionfof the metal to each mold, and tending .to amore uniform cast in each mold.

Another object of the invention is to provide a transfer-spout which can be made at minimum expense; one having adequate provision for receiving a refractory lining or brick and one which can be used over and over again without the necessity of re-lining the same forfsome time. L, In its more subordinate nature the invention also resides in those novel details of construction, combination and arrangement y lining brick being omitted. plication Serial No. 600,942, tiled November Application filed November 21, 1923. Serial No. 676,192.

l In the drawings, in which like numeralsy of reference indicate like parts in all of the figures, 1 represents the car on which the moids are conveyed to and from the furnace room where the metal is poured2 represents the mold stools, 3 the molds, 4 the lugs, 5 the mold slots in which the transfer spouts are set, 6 the collars, feeders orfhot top bricksof the .molds, 7 the distributing troughs having legs 9, and 8 the outlets `of the distributing troughs, all of which may be of any desired construction.

The transfer spout constituting the present invention is indicated by the reference numeral 10 and is shown in its preferred form in Figures 2 to 4 inclusive, by refer- `tends on two sides and one end by usng ence to which it will be seen that this transfer spout consists of anv elongated troughlike body having upright side walls 11 and. a bottom 12 which slants downwardly from the open or receiving end toward th closed or discharge end. j The upright wall 11 exof the spout as shown. v

f 13 designates side Ulugs with lifting eyes 14, by means of which the transfer spout can be put in place or removed as desired, the location of the lugs 13 with relation to the center of gravity of the structure as a such that when lifting the trough olf t e mold the receiving en will tend` to raise rs't and clear the metal of the o d in whose slot it sets while causing the fl id metal remainingl in the spoutv to flow toward the dischar e end vof the same. 15 is the discharge en of the spout which is referably laterally enlarged and is pro'- v'fFed with a recessed bottom 16 for the disc` arge hole 17. The recess A16 is provided to receive the bottom brick 18. This brick may be made of one or more pieces and assembled before placing in position in the trough, or it may be built'upcin the trough to building brick.- Frthernioreit may be made of firel clay, hot top brick. material' or any other suitable refractory material, and

when I use the term brick in this apvius lication I do not wish to be understood as limiting that term to any particular brick material or to any articular size of brick. The-enlarged disc arge end of the s out i-s alsopreferably provided with vertica refractory lining 19 which also may be made of onepiece or built up of several piecesmgf/present t invention whether the same 1s ma if desired, ithbeing immaterial to e of one or more'pieces and inserted in the assembled statein the spout or fwhether it be built up in the spout. Y c

The bottom brick 18 maybe a simple flat brick as showhin Figures 3 and 5 or 4it mayv be a flanged brick, as showninl Figure 6, in. which event the fiange/.20will set-into the hol'e\17 -and protectftheedges of the metal of the. spout there.

In the embodiment'of the `invention shown that t e upright wall llrconstitutin'gthe discharge end of the spout is lowered, as at 2l, in order to reduce weight' and save material of the spout, the required height being ,obtained by ythe lining. brick used, Ihthis embodiment of the invention thjos'e parts corresponding-to similar parts in the preferred embodiment bear the same reference-characters plus the index letter Wa.

In the embodiment shown in 4FiguresvlO to 12'inclusive, the parts which 'correspond in lirpose and function tol similar. parts .65

in t e preferred form ofthe invention bear ordinary brick, similar in s ize llarl be readil end having the res'7, 8l and 9 it will be observed kwith the hole `in` said bod having the end \wall, the bottom ,ofthe .that with' the hole,l

From the foregoi it'4 willbefseen that by the use of my new orm of' transfer s ,out the flowing stream of metal in passin om a higher to a'lower moldis-cau ht y the end wall of the out andgheld ack from spillin over the urther edge of the-mold t roug which it discharges and it also serves to directthe molten stream straight down from the transfer spout into the mold instead of throu h a curved trajectory as with the use of y formery out.`

Thesize' of the discharge ho will be regulated to permit the fiow of metal through the `same at a proper rate yto prevent the metal rising to an unsafev depth in the spout and the diameter of the Somewhat on the 'diameter of the discharge hole of the ladle or transfer box as will be clear to 'those skilled `in the art. f

AI may also provide the spout with a stopper`22 carried on an arm 23 of ya leverv which 1s pivoted at 24 to a bracket 25 on the side of the spout and which'has a'socketed larm 26' for; receiving a long rod by which the lever mayr be operated to raise and lower the stopper, whose construction is particu- -disclosed in Figures 13 to 15, inclusive. rom the foregoing description, takenin cpnnection with the accompanying drawings, it is thought-the complete construction,

uses and advantages of, my invention will Vclear to those skilled in Vthe art. What ,claim ,is:-
