bodimenta. 'it will 'he fahsesvedf that.l the known parts ofthe core and mold wherewith the saidv chaplet is associatedV and coacts have been designated by letters of reference, instead of numerals as are used to denote the presentk improvement. lThis was done it will be understood, merely to intimate that the said parts are not treated or considered as pertaining exclusively to the latter, but

are claimed herein only so far as they form therewith legitimate combinationsY of elements capable of yielding novel and useful results. Y l f Of these reference letters A identifies the Vwalls orsides of the lower part Yof a flask enclosing the sand 1n which the cast is made B the mold board whereon the flask with the packed molding sand therein, rests; C face of mold wherefrom the -pattern employed inmaking an impression in tlie'sa'nd has been withdrawn; Vand D core of sandheld at a certain distance from t-he face of the mold to afford a space E Ywhereinto the molten metal used to produce the casting, is poured.

The parts hereinbefore mentioned constitute the drag or bottom section from which the cope or upper part of the flask has been removed. The casting to be made when both flasks are fastened together, eXemplifyin'g` a six-sided hollow column. 3G

In order to carrythe core D and prevent the same from shifting' at suchtimes 'as' the fluid metal is poured into the mold space E, a number of chaplets are interposed between the core and the inner surface C of the mold at Various intervals according to its width and length. St-ructurally each of these chaplets is composed of three distinct parts, comprising a post or stud member and two similar flange elements, respectively designated bythe reference numerals 11 and 13, 15,. of which those last named are preferably alike and affixed at or adjoining the extremities of the member.

As' shown, the stud 11 consists of a piece of cylindrically shaped rod, the middle section of which may be flattened as Aat 17, so as to produce sidewise'extending comparatively sharp-cornered wings 19. The outer edges 21 of the latter, if desired, can be made relatively thin or drawn-out. As denoted at 23 there may be provided through the flattened portion or the wings, any number of openings, depending upon the size thereof. The presentexemplilication of the invention, shows one of these openings as be ing located centrally of the portion 17. By

preference, the material of the member inimity thereto rightangularly arranged shoulders 29. Intermediate .of the latter, the body of the'stud has formed thereon, one or more circumferential enlargements or annular appendages 31, the faces of which may be acutelybevelled or drawn together so as to meet in a trenchant edge or rim 33, overhanging the sides of the member, preferably all Varound the same. ln the embodiment of the invention illustrated, a pair of these enlargements are represented as disposed on either side of the flattened portion 17. Still it is conceivable that not'only a single but also a multiplicity of peripheral .protuberances may be formed with the surface of the said stud. rlhe above named necks 27,`if desired, can be recessed or cupped axially inward from their outer ends for a certain depth as at 34, in order to enable the same of being readily upset by blows or pressure applied thereon.

lTaking' over the said Ynecks below their outer extremities and abutting against the shoulders 29, are the' hereinbeforevmentioned flange elements 13, 15. Thev latter are pref erably of rectangular formation, and pro vided with apertures located substantially in the middle thereof Vandhaving Yatight or force fit engagement with the necks27. At 37 it is denoted, that the said flanges may be formed with open outwardly facing notches in the perimeters of the same. Through these Anotches are adapted to "be driven into the sides of the mold and the core, nails 39 or other headed pins capable of anchoring the combined flangeelements and stud memberconstituting the chaplet, firmly in assigned position to resist the onv rushingy sweep or force of the molten metal flowing around the same. lnstead ofV pushing the nails through thenotc'hes, the former may be placed as Adepicted in -lig. l, in paired relation around the opposite corners of a'flange, depending upenconditions and space available therefor.

lOl)

Before the Ycore D is placed in position Y within the mold C, the number of chaplets deemed necessary to support the former, are fastened to the side and bottom of the latter, by nails of suitable lengths stuck into the packed sand through or around those of the y elements serving as basal flangesv for the chaplets, inV accordance with the arrangement depicted 1n Fig. V. Next the core D is put in place within the mold, resting upon f the cap-flanges 13 lof the chaplets, which flanges are thenv anchored to the adjoining faces of the core in a manner similar to the before mentioned basal flanges l5. After,

thereof. The -hot flowing metal inl coming into contact with the thin "andrsharp corners 21, the tongues 25,' andthe edges 33,'Will cast into metal Walls exposed to fluid pres-y sure and a leakA shouldfhappen to develop cause these attenuated bondingl means to fuse andk combine With the molten metal `flowing around'the saine, which metal subsequently cools and 4contracts Vabout the chaplets, thereby becoming so firmly im-Y or appear around the necks, such leakage can readily be stopped bypeeningV over the extremities 340i the said necks. Both of the enlargements 19 and 31 will prevent the chaplets from being pushed through the Walls ofl the casting. Even if it' should be .required to drill a hole through the latter Where a chaplet occurs orV is located, the aforesaid enlargements z Will retain What remains of the' cha let a around the bored a opening, in place.

"foundry can convenientlykeep von hand quantities of these stud members of lcertain maximum lengthsihavling enlargements of this adoptedtype embodiedV therewith. And, as different jobs come up, itis merely a mater ofV cuttingo'lfl the ends of the studsl and forming necks thereon for the reception `of standard stock flanges. From the foregoingit Willbe per? cieved thata considerablejsaving of time and simplified procedure is attained by the.

use of thesev c haplets.V
