The invention is shown as appliedfor the purpose of supplying metal to amelting pot 10 and is illustrated in double form, so, that the tails cut from plates on two casting machines or units can be introduced into the same melting pot by these conveyers in a convenient manner. Itwill be understood thatthe melting pot is intended machine.

to supply the metal to the two casting machines. This invention does notrelate to any other part of the casting machine and therefore the drawings do notv illustrate any part of the casting inA Astantally the saine.

one meshing with a bevel gear 20 1oeated=on shafts,2l. These..shaf-ts. ,21. are locatedatiaconsiderable, `angle to theshaft "17 ',i-These -twokr shafts 21. therefore'.mai/...flue-,located vat-ian f ,angleof about E 90 Vdegrees'. apart. .on-f. at.\any,- eother;con venient "angle,- and they are supported in bear-7,10 ings 22 carried by aframe 23 which is supported in'inclined` position,` as indicated in Fig. o

The two driving,"` shafts 21` are located over`4` a side edge vofthe meltingpot. At opposite ends 'W5 n o of the two 'frames23 are similar shafts carry-` ing Vthe other end ofthe device. On each of these flour shafts 21 are located a pair of sprock. ets 25 which mesh with sockets 26 extending inwardlyjfr'om a series of slats 27 constituting .twormgg Y conveyers. i Each shaftat the opposite -end is also provided with idler sprockets for the same 'v purpose, vbut the sprockets 25 ofcourse arel keyed to the. shaft 2l, so that the conveyer is positively driven. This conveyer being 'composedi of 'cross-slats constitutes a moving platform ln'y each case `which moves out over the `melting pot and deposits all'loose objects on it vdirectly l into the melting pot and into the body of molten j metal'therein. VIt will Ab efobserved, from the position of the two conveyers shown, Ithat they are" adapted to receive the severed tails and `imper` fect plates from two units of an automatic stereotype casting plant and deliver al1 of them to the same melting pot.` n f i The purpose of slanting'the conveyer is to prevent the displacement of the Vtails and plates, thereon over the upper edge of the conveyer. By

xhaving `this slanting arrangement, the tails and plates-gradually work downto the lower edge .Modo

and there is no danger of their being `discharged over the higher edge. At the .lower edge is a` buler plate `29 which may be integral with the frame 1,23 or secured in any desired way, which extendsl clear out into a position'v over the molten metal in the melting pot 10, and thusthe plates and tails will be moved along substantiallyrin contact with this buffer plate and discharged in a position near the iniddle of the melting p'ot.

i y -lzwsl aus l ensjff" elo For kthe purpose of adjusting the tautness of the conveyers, the shaft 21, which constitutes the idler shaft to support the idle end of each' endless apron, is supported in a pair of brackets 32 having slots 33 and adapted to be tightened by screw 34 for each bracket. secured in positionby bolts 35. passing through the slotsv 33 and into the solid part of the frame 23. v

It lwill be obvious that the adjustment of the endless aprons or conveyers for taking up any slack in them is conveniently reached from oppositesides of the conveyers. It will `be seen also thatv each conveyer is so Vconstructed with a minimum of expense;th`at the plates andtails will move along one 'edge' thereof and-be de` posited out into the middle of the melting pot, Where molten metal will not be likely to splash lup on the machinery, and that two conveyers are shown as arranged for receiving tails and `platesvfrorn the" two casting machines spaced `apart as previously stated.
