To LH 'Lu/wht it mrtg concern:

Be it known that.. We, BERNARD T. Mo- GLONE. and GEORGE Rosspcitizens ofxthe AUnited States, residing at Chicago, Illinois, and Hammond, Indiana,.respectivel v, have invented certain new and useful- Improve- .ducing bus ments in asting-Machines,'of which K Our' vention.relatesto.casting-machines, and more Earticularlyivto machines fonproings ands'imilar articles; andits objects 'are toprovide, an apparatus of a simpleand'durablle construction which can be operated at. a Icoinparatively high speed, to provide ,an apparatus iii-which the finished article can be readilyreinoved from the mold,

ltofprovid'e anapparatus -wliicli will permit of the use cfa sectional lmatrix, whereby easy removahility of .the casting is attained,

and to previd'ea machine in Vwhich the ejector.

constitutes one sideofv the mold. These'objects and other l advantages, which will hereinafter appea-1",We attainbymeans of the construction illu stratedf-in preferred form in the accompanvingdrawings, wherein- Figure 1- is a yiew partly inl section and vpartly in elevation', oi our' improved apparatusfwith 'the 4parts in position for casting.

Fig. gis a vew'smilar tolfig. l of the upper part ofl the device withgtlie fn'iold-bottom in its raised position, the flatrx removed, and

a completed casting nestingg upon the `bottom just 'as itl comes fromtliernatrix; and Fig. 3

is a cross-section taken ontlie line 3 of Fig'. 1.

In the accompanying drawings the object illustrated as cast is a bushing, and thisis what 'the'l device is primarily i ended: to produce; but it is ap arent vth O a plied to t ie producti ,y "man other artic es and is not limited- .t'o bus ngs. The device consists of a flaskforcasing LLeupported upon a base 5 of any suitable yconstruction and to which it isi secured. Aimatrix 6 is slidably mounted within the casing and rests upon a reciprocable bttorn? ,operated by means of1a'rack'8, uponwhich it rests, mounted upon the base presently' described.

:The tbody portionl f ,theiraek hollow andis supportd'upon a verticalgguide 10, secured to the base axially in lin'eiwith and below the casing 4. The 'rack 8 'slides freely the invention may bey y. upon the guide 10- and is operated by means pieces of the` base 5. y

When it is desired to form a hollow article, a core-'piece 12 is secr red to the upper end of the vguide 10 and extends through the bottom 7 and matrix 6 into the capf13, which rests upon the top of the flask or casing 4. IThe core 12 also serves to; act as a guide for the movable bottoni 7, which slides freely thereon and serves to keep the same in alinement when it is beingraised by means of the rack 8 and pinion 9. i

In order to permit of the ready lremoval of the article cast from the matrix when the latter has been elevated above the casing in the position shown in Fig. 2, the matrix may be made in two parts,- as showninl Figs. 1 and .3, andmolt'enmetal is introduced into the matrix through the ouringgate14, formed in the periphery of t e same adjacent to the casing 4, and through the cap 13. The pouring-gate 14 is preferably located at the point on the periphery of the matrix where the two sections come together, as illustrated in Fig. 3.

From the foregoing it will be 'seenthatin an apparatus:constructed in accordance with our invention a great number of castings can be made in a vcomparatively short time, as the article can be removed from vthe mold as soon'as'it has set andthe mold again made ready/by the raising and lowering of the bottoniportion 7 without in any way disturbing the main flas'kor removing itl'from osition.

Furthermore, such an apparatus .Wi l permitl further be a parent that by the-use of a' matrix slidab ein the casing-there will not be the lresistance to sliding motion in removing the casting that there would be were the cast'- ing alone tov be pushed out, as' the heated metal would take 'a much firmer hold upon the side ofthe casing than the matrix does.

Other advantages of thedevice will readily occur to those familiar with the art'.

Having thus described our invention and illustrated its use, whatwe claim as new, and

. desire to secure by Letters `Patent, is the folv lowing:
