` f `Apprima@ aieiocioiierzv, i922. seiiai m5913861 Be it known that l, MILAN H, Fisi-iiima citizen of lthe United States, residing at Chicago, `in the county of Cook and State of illinois,` have invented certain new and v useful Improvements in Stereotypers? Casting Machines, of which the 'follovviiigis aA specification. y i l ,l My invention relates y'toda stereotypers `castinginachine and more particularly to a machine having a pair of spaced `platens against one of `which the inatrixuis Vii'laced, being heldthereagainst by vsuitable gauges which serve to confine the molten instal `to the desired space between the platens.

i Oneofthe objectscfiny invention is thev `provision vof a machine `of simple and rugged construction, inexpensive to` manufacture,

may be easily handled in making `clamping ineens therefor `so .arranged that the `platens maybe placed either in a substantially horizontal` or vertical `position againsty the respective frame portions by which arrangement the upper platen may be swung to the -vertical'positi on and thelower platen to the horizontal positionvn the iiiatiiiand gauges placed as desired on thejiiiner face of the lower platen, then the upper platen lowered onto the gauges and the v'two platens clamped together.3 Vihen the `platens are clamped togetherpthe matrix and gauges are firmly held in position and the two platens may then besvvung into the `verticalv position andv molten metal poured into the chamber thus provided and thecasting made.

:Itis a further objectr `of my invention to provide an arrangement whereby the distance between the platens may beivaried to make castings of different thicknesses,l for n example, typeehigh` or thin-plate,`the latter commonly being termedshivers, suitable gauges, of course, being provided'vfor the respective castings-` This object maybe acframe, while lthe lower platen is indirectly connected atene end :to l the supporting Afreine means of a pair of linke, means be@ platens are Vswung position.

`ing employed to clamp the platenstogether :at the other end. v i i Another object of my invention is thepro vision of means'wherebynot `on'lythe dis tance between `the platens may be varieolto make castings of different thicknesses ibut which will be so arranged that the two plat ens maybe brought together, regardless of the heightl of the gauge bars', wit-hout 4one being-shifted longitudinally relative to the other, thus reducing to a minimum* lany tendency for the gauge bars andinatrices to be shifted out 'of place when theplatens are being brought into operative relationship. i

ln one forniof my invention"eithertlie pivoted connection betweenthe links andthe fil-aine `or that between tlieflinks' andl the lower platenis made adj ustable; i In anotlier form of my invention L'sha`ped links' are y provided for connectingthe'lower platen to the `supporting frame, and adjusting screws are associated with the respective links in such mannerthat the innereiid of thelower platenl may be raisedbr lowered, when in the horizontal position,` relative' to the other,"

platen so that the upper platen may be swung down onto the gauges and locked` to the lower platen without "moving :the latter platen.

A further object of my invention is the provisionof a `metal potVtiltablymounted on the vertical fi'aiiie portion in combination with `ineansf'or heating the iiietal pot, so

" that molten inetal may flow directly from the pot into the casting `chamber when the upwardly into a vertical A; furtlierobject ofniy invention is the provision of novel quick-acting means, preferably adjustable,` for `clamping the two platens together. n *j The Ainvention `consists" in the novel constructions, arrangementsand devices to be herein after described and claimed i for Acarrying out the above statedbbjects and such other objects as will appear from the following description of certain preferred ernbodinients illustrated in thel accompanying drawings, wherein` i f i j Fig. 1 is a 4perspective view of 'a machine embodying'the principles of my invention,

Referring; now to the accompanying drawings,` the, supporting fran'ie-i-ncludes a rec tangular iirameworlr comprising longitudinally extending members 112 connected'bv W tBaIlSVerSe-ly extending members 13 andv 114,

the irameV being' mounted on legs 15. A. pair el vertically extending frame. members 16' are mounted on therespective frame members 12, being secured thereto by ,bolts 17, see 2', 3V and In; the Velllleodimenit illustrated in lfigs. to?y 8, inclusive, the frame meinbe 16. on vtheir sides have aligned reees '-s: 18,

Fig. 4,. for tire reception ot' the extremities odi a horizontally transversely extendingrod 119.v The upper platen 2,6) is provided on its inner or lower side with lugs 21 which are perforated? for the reception ot' the rod 19?.. pair of l.',-shaped` link members 22 is provided, ezlichz o'l'safid liinik members being perforated at one end for the reception of the rod 191and at the other end for the reeeption of'A fastening members `carried by the lower platen 24. The rod 19A is imrted tljrroughthe lugs. 21 ol the upper platen and. the links are placed in position on saidr' rod betere thevsecondz frame member 16 is secured in` place on the adjacent frame member 12.,

Eig. l the platens; are in what may be teamed-the make-up position, the upper p latieir in a vertical position and the lower platen in a. horizontaly position.` The platens are held in spaced relationship; and

,the molten metal is' contined in the casting chamber formed therebetweenby gauges of any desired construction. In the embodiment illustrated, theJ gauges comprise longitudinally extending barsy 25 and a trans- Iversely extendingbar 26.. Each of the bars 25 carries a bracket 27" so arranged that, when the,- inner or lower sides of the brackets bear against the bar 26, the bars 25 are at right anglesA t0. the bar 26 and the casting will be square on three sides. The bars 25 may be moved toward or away from each other so that castings. of various widths may be made.

The matrix (not shown) is placed against the upper side of the lower platen 24. and the gauge bars are placed thereover in the desir'edposition. Each of the links 22 is provided with a tapped recess 28, see Fig. 2', for the reception of an adjusting screw 29. The adjusting screws 29 are adapted to engage the under side ol the l'o-,wer' platen 2L1-- when said platen is in horizontal position. lVhen the platen 2t is in saicl position, it restsv upon the adjusting screws 20L tast.- ening members .3 pivoted in the outer ends or' the links 22, and the seat 13 which is secured to or made an integra-.l part ot' the transversel Jframe member 13. Tlrie adjusting screws 29 are set so, that the distance from the plane ot the upper sides oi'l the gauge bars to the axis of the rod 19, when the platen 241. isr in the horizontal position. is substantially equal to that Afrom the plane of the lower side ot" the platen 2O to the axis of said rod. The upper platen7 therefore, may be swung down against the upper faces of the gauge bars without causing any movement of the lower platen and without caus ing` the gauge bars themselves to shift on the lower platen.

The two platens may be locked together in any desired manner, but l preil'er to use a pair oit adjustable and q-uiifleactmg clamps of the construction shown in the drawings, see particularly Figs. (t and 7,. l lin-eferably provide on each side off the lower platen a fastening member 30 havingT a vertically extending portion 30 and a horizontally extending portion 30". rlhe portionl 30av is provided with a vertically extending slot 3.1 through which a screw 32 may be inserted. said screw being threaded into a suitable recess provided in the side of the platen. The portion 30 is tapped for the insertion of a set screw which is adapted tor engage the bottom. or outer side ofvv the platen. Links; 34 are attached at their lowery ends to the fastening member 30` by abolt A cam member 3.6 is attached toV the upper ends of. the links by. a boltl 327.', adapted to extend through theA- apertures 314 or? 314 of `the links, said cam member having a hanljle portion 3.6?. The upper platen is provided with a. lug 38 projecting laterally from each side, theselugsv being so positioned;I that they may be straddledby therespcctive pairs of links 34and they are also arranged so that they form seats for the respective cam menr bers 86.

ldhen the platens are in the position shown in Fig. 2, and the clampingmembers are. swung around to bring the cam .inembers into engagement with the seats on the respective lugs 38, the platens will be securely locked together, as shown in Figs. 2 to S, inclusive. By loosening'ithe screws 32', the respectiveiasteningmembers 8O may be adjusted relative to the upper Vplaten by turning the screws 33, the fastening members being secured in the desired position by tnrrf ing; home the screws 32. After `the platens have been locked together in the manner described, they may then be swung from the horizontal position shown inFig. 2 to the vertical position shown in Fig. 5, or vice versa. `A, latch member 39 is pivotally attached to one of the framemembers 1G is adapted to engage al catch 40 provided on one ofthe platens 'to `hold the platens in the vertical position.

"`A`metal pot 41 is pivotally mounted on the frame members 16 in snch manner that `the moltenv metal may `How therefrom,

through the spout 4la thereof, directly into the casting chamber formed between the two platens. The pot and the metaltherein are preferably heated by suitableA burners 42 connected with a source of gas or gasoline.

In Fig.` 2 typrvhig'h gauges are shown in place between the two platens. The adjustinp,v screws 29 in such case projectonly a relatively shortdistance ont of the links 22. In Fig. 8, thin-plate gauges a re sho wn in position between the two platensfandthe adjusting screws 29 are shown asextending a considerable distance out of the arms 22 so that thev inner end of `the lower platen will be raised sufficiently to make the distance from the plane of the ripper sides ot the "thinfplate gauges to the axis of the rod l),

when the lower platen is in the lilorizontal position, substantially equalv to that from the plane of the lower side of the platen 20 to the axis of the rod 19. When thin-plate gangcsare used, the bolt 37 is `renioved from the apertures 34 andniserted through the apertures 34h to clamp the platens together in closer relationship. An adjustable con-- neiction is provided, therefore, between the links 34 and the cam member. Any inaccuracies in manufacture or wear may be taken care of by loosening' the screws 32 adjusting the screwsv 33, and then turning the screws 32 home.

In Figs. 9 and l() a modified arrangement of connecting the two platens to the framework is illustrated. In this embodiment a pair of standards 43 is secured by screws 44 to the frame members 12. The upper ends of said standards are perforated for the re.-

ception 'of a transversely extending,A rod 45. The upper plat-enst is `provided with a pair of perforated lugs 47 through which the rod may be inserted. A pair of links 4S per- 'lorated at their upper ends are placed on the rod 45. In this embodiment the lower platen 4i) is also provided with a pair of perforated lugs 50. Each of the links 4S adjacent their lower ends is provided with perforations 48" and 48" adapted to receive a screw When type-higl'i castings are to be made, the screws 51. are inserted through the perfor-ations '48" and, when thin-plate castings are to be made, they are inserted through the perforations 4S" of the respectivo links 48. An adjustable connection is, therefore, provided between the links 4'. and the platen 49. The platens are clamped together and the machine is operated in a manner similar to thecmbodi` ment hereinbefore described. I do not intend to liniit my invention to the details of construction shown and described herein, eXcept only in sofaras certain of ythe appended claims are specifically so limited, as it will be obvious that varioiis modifications may be made by those skilled in the art without departing from the prin- Eciples of the invention.
