the slide mounted in the carrier and adapted to slide therein for the purpose of conveying the mold from casting; to ejecting` position.v

The mold proper consists of tour members, viz: the lower jaw or' body l; the upper jew or cap 9.; and the two springinipelled, spring-yielding, side pieces 3 and 5 housed, the one,3,in the lower ian',:ind the other, 5, in the upper jew, and termin the side walls ofthe slot. They :ire spring pressed, by springs i. and (3, each toward the fece ot the y 'opposite jaw, forming' tight fitting side wells which are self-adjusting to variations mdis tance betweenthe upper and lower jaws. rlhe upper `inw is capable of vertical movement to and from the lower jaw in orderto vary the width o'l the slot, and pressed upward by the sido pieces 3, 5, which tend to open the mold, it moves up and down in guides 1G in the slide-there being a tongue and grooveyor equivalent., connection tween the slide and the inw, whereby the letter, as it moves up and down, is held in its proper relation to the lower jaw. T he lower 'uw l is seated in al ugreove in the lower portion of slide l and is held in place .between the back of the slide and the trent plate S, which term a guideway wherein the jaw can more lengthwise. This movement of the lower jaw will, according lo itsdireo tion7 cause the side piece 2% which it. carries te apln'oach or recede irom the other side piece 5, thns varying the length of the slot as desired. '.lhe slide lr held and `guided in its movements in the carrier G, by :i longitudinal rib 30 on its top', which enters a corresponding groove inthe carrier; and by a rib 2L). on its bottom, which enters a. cor'- respondingguido slot or groove in the carrier. The slide may be moved at propel' intoi-vals, from casting to eje'cting` position 'and return, by'any suitable means-tyliilied in the drawing (Fig. l) bythe connected by link 5l to the slide, said pitman rod being actuated by any proper means. ln lieu of this arrangement for actuatingl the slide l :an use the rack and pinion arrangement illustrated in my aforesaid application Serial No. 308,522. rlhe parts aS thus far described are substantially similar in general construction and operation to the pnrtsidentitied by like reference characters in my application Serial No. 303,522.

l come now to th ose portions of the mechfm'ism wliich'ennbody my improvements..

The side piece 3, which Jorms the lei-l.

.bearing upwardly hand side wall of the mold Islot' in Fig. l. is prolonged in the form of a lengthwise extendiug'sirijp oi' bar c solid with the piece l andthe other end of this bar a is supported and upwardly pressed by a second spring l,

similar in construction.` arrangement and function to the spring il which supports and upwardly presses the side piece tl. This liar of the jaw a is so arranged and formed that when the length of the slot is decreased by moving the lower jaw l. and consequently the side piece the uinised portion of of the melting pol, he exposed. '"llie bar f/ is vertically slotted lower I ,serving as a guido tosteady and hold the .spout 'closing barfor prolongation a, in propel' position during its up alid down movements. ',lhe upperjaw also has a tail or prolongation "c which extends through/a the left hand guide slot orv opening Ai i standard I6 in the slide F, and .bears upon the upper face of the bar u when the parts are-iii the'position sliownin Figxll. In this way the side piece/3 gets a broatLeXtended against the upper-sjaw. *whichl permits it the side piece) to be -niorcd to contract the length ot' 'the mold space oi"3slotfwitliout any danger of the ofthe upper jaw which point between the two. To adjlls't 'the u per jaw for the purpose of varyingthewit th of the slot, I make use preferably on the jaw, and the latter on the slide in whlch the jaw is'mounted. And with this niechanlsin I combine means by which the pinion carrying shaft, before the ejceting the drawing in the of the cast slug, is automatically rot-ated iii afdirection and far enough to relieve the pressure of the upper jaw upon the slug; .and also-means by which the shaft is autoniafticallyA returned to-its original position a er the operation of ejecting lthe cast slug a d beforel the o eration ofcasting another s-ie'. Devices fdr. these purposes ca n be widely varied. They ai'e represented in form in which I now prefer to .employ them.

Upon the back of the upper jaw, are

"-fornied or'attached two vertical toothett racks d, and meshing with these racks are two pinions e, is niountcdvto revolve in bearings g on the slide, and is provided at one end with any suitable' operating 1neans-for example the handle L-as shown more clearly in Figs. 1, 2, 6.- By turning the. handle to'rotate the shaft in one d' ection or the other, it will be' seen that t e upper jaw can be raised t lowered so asjto be placed at the desired tance from /the lower jaw. The upper Jaw of a rack andpinion inechanism--tlie former.

fast upon a shaft f which is secured in adjusted position by any proper means-in this instance by a :spring pressed deteiit pin z' in the handle which will enter the selected one of a a suitable portion of the mold. vide forythe automatic opening and closing Q, the holes j are formed in the arc of a circle in the outer portion of an arm It: mounted loosely on a hub f on shaft 7", on which it can move, and connected with y shaft f' by a helical spring Z which tends to 3, to the right. it will cover and close the month in the spout which otherwise would l turn the arm le, and consequently the shaft f,

1n the direction indicated by the arrow 1n F 10s. 5 and G that is to sav 1n a direction j' which will tend to cause the pinions c to deas at n, Fig. 'EL to receive a tongue on the jaw which extends up into the slot. f

. 4. t5 combined.

limited by a press the upper jaw against the stress of the opposed springs l, (S of the lside pieces 3, 5, the spring Z being-stronger'than the springs '.lhe movement of arin 'f in th/e direction of the arrow (Figs. 5 and 6) is stop m, on the slide against whichit brings up and normally rests.

In Figs. (3 and 7 is shown one means of automatically eti'ecting the slight .lift-ing of the upper jaw I leferrnig to these figures, n is a stud or projection with rounded end, extendingrearwardly from the outer end of arm and o is an incline secured to the ejeeting end of the -oarrier fi'aine G in such position that j ust before the slide F in its travel from casting position reaches ejecting position the stud n. will meet the incline o and by the continued movement of the slide F will be caused to travel over the inclined surface of o with the resultof forcibly turning the arm 7n, and consequently the shaft f, against the stress of spring l, in a direction to lift the upper jaw, so that by the time the slide reaches ejecting position, the mold will have been automatically opened to the desired extent. j. 1 l A j ln Fig. 7 the stud 4is represented in dotted lines in thel position it occupies when the parts are in ejecting .position-liaving travei-sed the incline. alid resting against a Hat surface beyond' the incline where it is held vso long as A s soon', however, asthe mold. on its returni the mold is in ejecting position.

to casting position'lnoves far Venough to disengage the stud from the incline, the mold will automatically close and the parts will resume normal position. Iii lieu of this mechanism, I ma v use a plunger p (indicated diagranimatically iniFi l and 5) which `will reciprocate in a gulde 1'2 on the carrier frame, and be operated by zr'rocker arin s2 (Fig-5) for example, connected and deriving its motion from some suitable part of the machine; and vill o eratpi at the ro er time afrainst a epen ing4 nger' IFiu- 5) on thte arm c,'l pushing that `iigir and consequently the arm k back far enough to lift the upper jaw the requi `l distance before the ejector acts. I have not deemed series of holes y' in prior to ejectiiig the cast slug.

lic

il i5 vfro movement of the mold.

` justed position of ing position w ermee it necessaryT to represent the actuating mechanism here. Any suitable mechanism of the kind can be employed, as for example that. shown in my Patent llo. 834,971 or November 6, 1905.

lt remains `to describe the mechanism for moving the lower jew lengthwise for the purpose of changing the length of thc slot and for automatically opening` and closing the slot in this direction during the to and lily mold in this respect, is characterized by the combination with the member which is longitudinally movable in relation to the others for the purpose of changing the length of the slot, ot stops i'or automatically and positively opening and closing the mold to one length or another during its movement to a nd irc. This feature is not here broadly claimed, inasmuch as it is the subject (among others) of my application ior a vpatent for improvement inline casting i. achines Serial No, 432,605, filed May 13, 1.988. ln said last.- named application one o' the stops is a fixed stop which automatically opens the ,mold al: ways to maximum length, and the other is an independently adjustable stop which art-y tomatically closes" the mold to one length or another as desired.

ln my present application, the twostops are placed at e dist-ance apart slightly less than the length of traverse of the mold, and are so connected asto be adjustable bodily and together, the distance between them being invariable, so that the automatic opening movement of the mold will always be the same in extentwhatever may be the zid-v the stops. ln the drawing the two stops are shown at r, rf; are attached to opposite ends ot ti e slotted. bar s Jfrom the face of which they project in the pathxof a vertical bar t attached, et. its ends .to the carrier G and extending down in front ot the mold. yThe bar .9, which on top of front plate 8, is arranged horizontally on the front face of the lower jaw i,

ejector or its -passing between it and the vertical barI t.

w il by set and is adjustably secured to the ja slot in the screw s which passes through the bar into: the lower jaw. Thebar s can be adjusted back and forth vto change the relation 'of-the stops 7', r to the intermediate vertical bar and can then, by tiglitoniuig; the set screw, be held firmly in its adjuster position. A, scale can be formed on the bar s, a. shown, to facilitate adjustment as usua in devices of this character.

The closingstop is r; fr is the opening stop. ln Fig. l the mold is shown'in cast-- ith its members in position to forni :t slot of maximum dimensions in both directions. ln movingv from casting` to ejectingposition, stop 7, just before the mold reaches'lejectink position, brings up against bar t, thushol ing bach the lower jew while' they.

i l l l the rest of the mold moves forward. and consequontly increasing the distance between the side. pieces 3, 5, or in other words the length ot' the slot. Un the-return movement of the mold the reverse action takes place; the closing stop i' brings up against the bar 1, and holds the lower jaw motionless, while the remainder oi" the mold moves 'back `to casting position. To decrease the lengthof the slot, the bnr s, while the mold is in ejecting` position, is adjusted to the left, so as to bring' the stop fr' sooner into contact with -the bar t' during the return movement of the mold, es will be understood without further explanafrigm. I
