STEREOTYPERS CASTING MACHINE.

Application filed November My invention relates to a stereotypers casting machine and more particularly to a machine having a pair ol spaced platens against one ot which the matriX is placed,V

" stantially horizontal and vertical portions;

and a Further object ot' my invention is the provision ot a pair of platens and suitable hinging and locking means theretor so arranged that the platens may be placed either in a substantially horizontal or vertical position by which arrangement the upper platen may be swung to the vertical position and the lower platen to the horizontal position, the matrix and gauges placed as desired on the inner face of the lower platen, then the upper platen lowered onto the gauges and thc two platens locked together. When the platens are locked together, the matrix and gauges are firmly held in position and the two platens may then be swung into the vertical position and molten metal poured into the chamber thus provided andthe casting made.

A lurther object of my invention is the provision of means for connecting the platcns to the supporting trame so arranged that said platens may be swung about either ot two axes, one ot said axes preferably eX- tending vertically and the other horizontally. In carrying out this feature ot my invention l. prei'ieraliily provide a yoke pivotally connected to the trame so that it may be swung about a vertical axis and to which the platens are pivotcd, the pivotal connection between. the platens and the yoke member being so arranged that the platens are substantially balanced on the yoke member and, therefore, easily swung from a horizontal to a vertical position or vice versa.

.It is a further object oi my invention to provide an arrangement whereby the distance between the platens may be conveniently varied to make castings of different thicknesses, for example, type-high or thinplate, the latter commonly being termed 9, 1922. Serial No. 599,821.

sl-rivers, suitable gauges, ot course, being provided tor the respective castings.

A further object ot my invention is the provision ot a novel adjustable hinge for connecting the two platens.

A further object of my invention is the provision of novel quick-acting means, preferably adjustable, 'for locking the two platens together.

A further object ot my invention is the provision of a metal pot tiltably mounted on the vertical frame portion in combination with means for heating the metal pot so that molten metal may flow directly from the pot into the casting chamber when the platens are swung upwardly into a vertical position.

The invention consists in the novel constructions, arrangements and devices to be hereinafter described and claimed tor carrying out the above stated objects and such other objects as will appear trom the tollewing description oit certain preferred embodiments illustrated in the accompanying drawings, wherein- Fig. 1 is a perspective view of a machine embodying th principles of my invention, the lower platen being in the horizontal position, and the upper platen having been swung back so that the matrix and gauge bars may be properly positioned on the inner face of the lower platen;

Fig, 2 is a perspective view of the machine, showing the platens in the vertical position so that the molten metal may be poured into the casting chamber therebetween;

Fig. 3 is a plan view of the machine, certain portions being broken away, showing the lower platen in the same position as it occupies in Fig. l, the upper platen, however, having been swung down into operative relationsip with the lower platen and locked to it;

Fig. L is a sectional vView taken On the line t-fi of Fig. 3, the two platens, however, having been swung in a horizontal plane from the position shown in Fig. 3 through an angle of 900;

Fig. 5 is a sectional view taken On the line 5 5 of Fig. li;

Fig. G is a side elevational view, certain parts being sectioned, of one of the hinges preferably employed tor connecting the platens;

llt)

The two platens may be locke-d iiico-operating relationship by any desired means, but I preier to use a pair of quick-acting, adjustable locking devices of the construction shown in the drawings, see particularly Figs. 7 and S. rlhe

respective platens

23 and 25 are provided with lugs 37 and 38. Each lug 37 is provided with a slot 39 for the insertion ot a bolt 40. Links 41 adapted to be positioned against the respect-ive sides of the lugs 37 and 38 are pivotally connected at their lower ends to the lug 37 by the bolt 40. Adjacent their upper ends said respective links are provided with peritorations 41a and 41", through which a bolt 42 may be inserted, said bolt being shown as extending through the peillorations 41a. A cam member 43 is attached to the upper ends of said links by the bolt 42 and is adapted to engage the seat formed on the upper surface of the lug 38, said cam member having a handle portion 43a. When the platens are in the position shown in Fig. 1, the locking devices hang downwardly, out of the way, and, when the platens are in the position shown in Fig. 3, the locking devices may be swung upwardly to bring the cam members. into engagement with the seats on the respective lugs 3S, thus locking the platens ton gether, as shown in Figs. 2 to 5, inclusive. The lugs are tapped for the insertion oit adjust-ing screws44, the inner ends ot' said screws being adapted to bear against the upper sides of the respective bolts 40.

ln Figs. 1 to 3, inclusive, type-high gauges are shown in place between the two platens, and, when such. gauges are used, the bolts 33 of the hinges 26 are inserted through the apertures a of the links 35, and likewise the bolts 42 of the locking devices 27 are inserted through the apertures 41a of the links 41. In Fig. 9 thin-plate gauges 45 are shown in position between the two platens, and, in that case, the bolts 33 of the hinges 26 are inserted through the apertures 35" of the links 35, and the bolts 42 of the locking devices 27 are inserted through the apertures 41" oit the links 41, thereby bringing the platens together in closer relationship. 1t will be seen, therefore, that adjustable connections are provided between the links 35 ot the respective hinges 26 and the platen 23 and also adjustable connections are provided between the links 41 and the cam members 43 of the respective locking devices. 1n order to take care of any inaccuracies in manufacture and any wear that may develop, provision is made :tor varying the distances between the bolts 33 and 34 of the respective hinges and the bolts 4() and 42 et the respective locking devices, this being accomplished by turning the screws 3G of the hinges and the screws 44 of the locking devices. By this arrangement a very iine adjustment is obtained and the platens may be brought into close fitting engagement against the respective sides of the gauge bars.

A metal pot 46 is positioned on brackets 47 carried by the respective vertical :trame members 16. At each side the metal pot is provided with a pair of spaced, laterally projecting lugs which are adapted to lie in suitable recesses provided in' the bracket members 4i'. This arrangenient makes it inipossible to tilt the metal pot accidentally and yet permits the molten metal to flow from the pot through the spout 4Gb thereof directly into the casting chamber formed between the two platens. The platen 23 is provided with a portion 23a to direct the molten metal into the casting chamber. The portion 23u may be made in the form of a handle, see Fig. 3, to facilitate handling the platens. rllhe pot and metal therein are preterably heated by suitable burners 48 connected with a source of gas or gasoline.

The traine is provided with a foot-piece 49, see Figs. 2, 5 and 9, which forms a sup.- port lor the right-hand end of the platens, having reference to Figs. 1 and 3, when they are in the aositions shown therein. The piece 49 and the bottom of the yoke 18 prevent the platens rocking to any appreciable extent on the members 24, the piece 49 being particularly useful when a small casting is made in the bottom of the casting chamber, in which case the tendency for the platens to tilt clockwise being much greater than when. full size castings are made.

I do not intend to limit my invention to the details of construction shown and described herein, except only in so far as certain of the appended claims are specifically so limited, as it will be obvious that various modifications may be made by those skilled in the art without departing from the principles of the invention.
