'lhe structure@shown in the drawings is designed as an iri'iproveinent upon a casting machine for which Patent No. 928,246, was

.granted to me July 2t), 1909,' and in respect to general arrangement and many details ot' construction, it is substantially the same as thatshtnvn in said patent, and in respect to these 'general features and details it will be described only so tar as necessary Jfor understanding of the features constituting the vpresent invent-ion-,

apertured for, and adapted, if desired, to be journaled upo-n, the central cupola standard The means for rotating this Wheel about its vertical axis are not shown. 'It may be understood that it is rotated by any convenient means adapted for arresting it in any point in its rotation, as may be required -by the exigencies of the process of casting.

The molds, 6, of which a multiplicity are mounted upon the periphery of the Wheel, 5, are substantially of the construction shown in my said former patent, each comprising a member 7 mounted rigidly upon `the wheel, 5, and a member, 8, hinged to said rigidly mounted member for opening and closing the mold. Each of thehinged members is provided withfan anti-friction pulley, 9, for encounter With tlieffnlold-closing cams 10, of which one is shown at one side of the machine, a similar and similarly positioned device being shown at the opposite side of the machine, it being intended that the machine shall have at least these two operating stations where molds will be filled as the wheel revolves to carry the molds past said stations respectively. Each of the cams 10 is extended so as to hold a plurality of molds closed at one time. As illustrated, the extent of theI cam is such as to hold four molds completely closed while ,the fifth one is engaged andbeing closed.-

Tlis cani plate is mounted by means of a plurality of stems 11, 11,y which extend through horizontal slide-bearings in a rigid post, 13, springs-14 being coiled about said stems and reacting between the post and the cani plate for holding the cam plate thrust toward the axis of the mold-carrying-\\'heel, for pressing the hinged mold members which'are engaged by it into closed position with the amount of force determined by the tension of the springs, 14. The molds are designed to be tripped open after they .have traveled past'the cam 10, andto a sufficient distance from the point l Voyer, l5, which therefrom, and

at Whichthey were Atllled when shut by the cam, so that the casting is suflicicntly cooled to retainthe form after the inold is opened, and any convenient means not shown may be provided forthus opening the mold, the means shown in my former patent being suitable. At the point in the travel of the molds with. thel nuold-carrying` Wheel at Whichit is considered suitable to open the molds, there is provided an rendless conextends under the path of the molds for receiving the castings dropped carrying them away to a proper point for deposit.

The cupola, 4f, is supported upon the post or central standard 3, by means of a spider or .skeleton urn, 16, which is niounted upon A the top of said post, and terminales in. au

l gases, and at the lower end, in a spouts 25, which are provided and chamber Vadniiature of air and annular top Harige, l?, onto which the annular base 18 of the Crucible shell is bolted, said base ,having its central opening provided with a'trap bot-torn, 1t), adapted to be Withdrawn'to permit the dumping ol' the contents of the cupola, when so desired, such 2li dumped contents being received in the sleleton urn or spider, 16, and removed through -the openings between its skeleton arias.

The cupola comprises a cylindrical chamber 20, terminating at the upper end in a reduced cylindrical mouth 21, for discharge ont melting; chamber 22, which is enlarged in diameter intermediate its upper and lower ends, being in general comprised of two cone irustuuis .mounted with their larger b ses tiigether, as seen clearly ,in Fig. l. The entire cupola structure is lined with lire-brick 23, the bottom having such tirebrick liningl 221, being made crowning, so that the liquid metal will low ed therefrom for discharge through distrihuted about the axis of the cupola in number and position corresponding preferably to vthe number and position of thelstations at which the inoldolosing` canis 10 are provided and an operator is to be stationed.

The melting of the metal in the cupola is designed to be effected by ineans of oil burners, 26 of which four are shown (Llistributed about' the circumference of the meltingl tor iuiof said chamber. Said oil burners are all connected to an airsupply trunk, 27, and an oil supply trunk, 2S, forproducing a proper gas to edect perfect combustion without the other supply of air to the cupola. For starting the melting, it may be. desirable to use charcoal or colte placed in the ably nioistened by a combustible liquid so as to be readily ignited by r i thrown into the crumble, and for supplying air for such "combustion, one or more oli the.

l from the roof there of the cupola, and discharging rae dially and downwardly ther-cinto pingeinent upon theinetal in the lower part.

bottoni of the'cupola and suitf intersect said circle at l a lighted tane-rf mantas l burners may be employed as a blower, the oil supply being cut oil from it for thc time l being. Also, in the ordinary. operation of i' the furnace, under some circumstances it i may be found desirable to operate one or l more of the burners as blowers only-that is,

without admitting` oil thereto.

The cupola is represented as extending up through the roof 30 of the building in which it is located, for the discharge ot gases, and

.is suspended, by means ot a pipe structure 3l, anrannular platform 32 encompassing the cupola above the coinbustion chamber for accommodating the attendant who will .supply the ore to the cupola through the latter door 33.

'lhc molten .metal designed to he drawn troni the discharge'spouts into pourers 35, which are,' in etlect, crucibles adapted to be kept hot by oil burners, '36, with whichA the.' are respectively provided, such burners i being; supplied with oil and air by flexible pipe connections leading` from the trunks, 27 and 28, respectively. These metal receptacles or poul-ersl are provided in` number corresponding tothe number oli' stations, and are mounted 'lor swinging in a horizontal plane about the wheel, so that their pmlring` spouts 137 may mferlnuig'and 'follow through their swinging movement the path of the molds to be illed. For mounting these pourers, they are each connected by a radius rod 3l) with the central post or slaiulard, l, such connection being pivotal al' the center ot said lpost, as hereinafter more particularly explained. These radius rods, however, are not relied upon for holding` the weight ol: the pourers, but tor that purpose there is toi-ined on the mold-carrying wheel an annular track .flange J0, and eachfol the pourers is provided with two wheels il resting upon such track. i

The molds are each provided with flaring or fiu'inel-shaperil, but horizontally oblong receiving` mouths Itil, said mouths being rendered oblong` by elongation to other in the line of lthe cireiunfcrence of a circle about the airis oit vthe nucld-cariyingy l wheel, the radius of such circle being .less

than the distance from4 said axis to the parting` plane oli' the molds; lfrein which it re salts that the meetings olf said elongated funnebshaped mouths, being' in the circumference oit such circle are positioned on the members of thev unnelshaped inouths which axis of the niold-(auryiug -pertain to the lined members respectively of ,the molds. `lnhe discharge spouts 3'? ofthe pourei:s terminate tor .causingthe path of discharge of the inolten metal 'therefrom to ot the elongated funnel mouths ol the molds are` situated, that is, so that in." t

he poorer in a path. which said which the meetingsl l will cross ineetntags. This enables'the operator to'.

strewnA of molten int-tal will be carried theswing l aomae "pass from mold 'to mold in curing withont interrupting the flow of t e metal; and when the molds are of auch a capacity that they can beflled substantially during the length of time occupied by the molds in 'passing a given point in their travel with the carrying wheel, the operator needs only to watch the molds and swing the poorer a lit-` length'of time required lfor lling` them is materially greater than the time which they occupy in passing a given point, the operator will be able to avoid either interrupt;`- Aing the rotation of the carrying Wheel or interrupting the-flow' of metal for a''considv erable time, because there are at all times "filling, andby beginning to pour with anyfour. molds `in position and condition for 'vennioldy immediately upon its entrance `svfingthe pourer so as to remain with the -mold until it is filled. Then swinging back to the nextfollowing mold, the saine process may be re cated until the margin afforded by the lengt of travel of the molds past the Jcam is exhausted. It will then be necessary f tio-halt thecarrier while filling the remaindel f the molds which are engaged with the cam, after which it may be started and the order of operations repeated. vWhen "the capacity of the molds is such that each mold can be filled in lesstiine than is occu- ,pied by its travel past a given point, the

operator will swing the pourer so as to be-' gin filling with the'niold which is nearest to the point for passing out from behind the cam, provided it has yet sul'licient travel to permit it to be filled before escaping the clim, and will swing the poni-er from that 'point back successively over the molds which .i are engaged with the cani until lie has filled a tiiiold which has just entered behind the --Qcam and been closed thereby.

lt will then be necessary to intcrrui'it the flow of metal While additional molds enter behind the cani and are closed ready for filling. Usually iti'will be impossible to increase the speed of the carrier so as to avoid any loss of time byv reason of the molds filling in less time than they pass a given point. And sinn-4 larly, when all the molds are alike, it may .he preferred to slow up the rotation of the (it)A 'and niiiiiinn'in number of interruptions of citherthe rotation of the-carriery or the tlow ack of' the closing cam, the operator mayof the metal, when either the molds are too small or too large to permit the necessary adaptation of the speed of the carrier to the time required for filling, or when the carrier has molds of a Variety of sizes at different parts of. its circumference, so that it is y.impossible to accommodateV all of them by adjusting the speed of the carrier. Y

The particular means shown for pivotally i connecting the radius rod to the/center post,

3, consists in making init-he posts, at points corresponding to the position 'of the radius, apertures 3d of angular extent,y correspond- 'ing tothe necessary swinging of the poni-e1', insertingkthrough said slots a pivotI plate 45,r

Whoelength 'is equal td the exterior diameter df\t he post, so that its ends lodge upon the lower .marginslof the slots and are flush 'with the outside of the post. lleinfr'cing plates -16 are bolted'onto the outside of the post to make good the loss of strength caused by the slots, andv these reinforcing plates have slots 46 only snflieient in width to permit the emergence through them of the radins rods, the .slots 3 being in verti- ,cal Width' much greater than that. as the thickness of the pivot plate 45, so that the reinforcing plates lap the ends of the pivot plate, and retain it in the post. The radius rodshaving' their inner ends flattened. are inserted through the slots in the reinforcing plates and post, and the pivot pin47 Pis inserted through them and through vthe plate frointhe upper end of the post.

ln order to facilitate the cooling of the molds, and also to reinforce them against liability of warping, they are provided with exterior vertical ribs 48, which tend to form vertical channels, 'tending to induce upward circulation of the air through them, be-

tween the ribs,aiid thus increase the cooling I etl'ect, in addition to th'e ordinary increase duc to the increase of the radiating surface.

-ln order that the material flowing from the spout', ot' the porci' may be delivered ceiltrally into the inold with niininiuin liability to bc lodged upon the margin ol' theopeiiing, with thc resulting tendency to clogl the saine by cooling in thaty position, it is desirabliI that the spout [should extend a liltlc down-- ward in the flaring funnel mouthpiece, as secu in lig. il, a'nd in ordci: that itv may thus extend and still permit the molds to travel past it1 the bridge or partition between the consecutive l'unncl mouths at` thc meeting point is provided with a slight notch 4st), which makes a path for the lowcr lip of thc spout` as thc molds travel past. it, or as the illci' is swung from mold to inold, as describi-d.

Vdi" closing the spout. ol' the pouiei', there is sho-wn a device` which is also ,chown in in latent, No. 928,246, consisting of the plug o3, carried in aslide-bar (il, mounted in the bracket arin 65, and operated hy u level' 66.
