T his providing of the right angularly extending hinge knuckles l t on the lower end of the platen ll adapts said platen to be held and remain in upright position as shown in Fig. 3 without requiring any auxiliary fastening means. This is due to ti 0 fact that these laterally extending knuckles lt pivotally connect said platens with the pintles 13 in ollset relation, so that when the platen is swung upward it will be olt center and thus he held by gravity in this position. Moreove1.',-this a 'rangement oi the hinge knuckles and the connection with the two platens provides for the holding of the plat-ens in upright position when they are con ected together to receive the molten metal as shown in Fig. 2 and it also provides for one plate or both standing upright without the use of any locks 0r latches.

In Fig. 3 the platens are shown in open position with the cast stereotype shown on the bottom platen. This position is also what may be termed the make-up' posh tion, which is the position occupied by the platens when preparing them for the reception of the molten metal before the castings are stereotyped. lhe platens are held in spaced relationship and the molten metal is confined in the casting chamber termed between the platens by of any desired construction. In the embodiment illustrated. the gauges comprise longitudinally extending bars 3 and 32 and a transversely attending bar 333. These bars are held together by the clamping action of the two platens and the bars 3 1. and 32 may he 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 .tace ol the lower platen l and the gauge bars nl, 32 and 33 are placed thereover in the desired positions. The bars Ill and 32 are provided. at their outer ends with handles 34- which project beyond the platens when in operative position a d may be used to facilitate the manipulation of the connected platens, as wet as .i'or the manipulation of the bars in relation to each other.

Then the matrix and the gauges are properly positioned the upper platen 11 may be swung down against the upper faces of the gauge bars without causing any movement of the lower platen and without causing the bars to shift on the platen. It is understood that when the platens 10 and 11 with the matrix are arranged as described and lock d together by the locking elements 19, a casting chamber will be provided between the bars 31, 32 and the opposed faces of the matrix on platen 10 and over which is arranged platen 11, the transverse bar 33 forming a bottom for said chamber. The opening to receive the molten metal is formed at the upger end of the connected platens, as is clearly seen in Fig. 2.

The locking elements 19 are preferably constructed in the form of quick acting clamps ot the construction shown in the drawings and each comprises a threaded rod or bolt 35 pivoted at one end in the notch 18 of the platen 10 and adapted to swing downward and upward to permit the platen 11 to be positioned over or released from the platen 10. his rod 35, when the platen ll is swung down over platen 1.0, enters one of the notches l8 at the sides ol the platen 11 and thereby holds the platens against sliding movement relative to each other and when the sleeve 36 which is threadedly mounted on the rod 2-3.3 is screwed. down into clamping engagement with the outer face of the platen H, the two platens are securely locked together and held inst swinging toward or away from each other. Operating handles 37 for the sleeves 36 are shown passed transversely therethrough for turning the sleeves into clamping or releasing position, providing the necessary leverage to securely clamp the platens in operative positions.

After the platens have been lot-.ted together with the matrix between them in the manner above descibed, they may then he swung from the horizontal position shown in Fig. l to the vertical position shown in Fig. 2, or vice versa. The metal pot or receptacle is pivotally mounted on the standards the. pivot or trunnion 2t being shown located forward Oil the center of the receptacle so that said receptacle will always retain its position when not in use, and yet pern'lit it to be freely swung downward to bring the spout- 22 thereof into register with the funnel 223 which is positioned to register with the open upper end of the casting chamber between the platens when the platens are in upswung position, as shown clearly in Fig. 2.

The funnel 223 is shown mounted on a cross plate or bar 40 which. is mounted between the standards 5 and has laterally extending ends 4;]. bolted to said standards, as shown clearly in Figs. 2 and 3. This funnel 23 is open throughout its length at the inner side thereot', as shown at ill to adapt it to receive the spout 22 when the receptacle 20 is tilted on its t nnnions to pour the metal, the walls of said tunnel operating as guides for the spout.

An operating handle or lever 25 is preferably secured to one end of the vessel 20 to facilitate the tilting thereof for placing it into operative and inoperative position. The depth of the funnel from its open face to its rear wall is such as to take care of any variation in the position of the pouring spout 22 in its travel during the different tilting stages of the pot 20 during the pouring operation. The outer or rear wall of the funnel is curved at its lower end as shown in Fig. 2 and operates to deflect the molten metal from the spout away from the mat and direct it against the platen 11 thereby avoiding burning of the mat by contact with the hot metal. It will thus be seen thatthe entering ho-t metal follows the rear side of the casting chamber to the bottom where it spreads and rises equally at all points causing any dross or foreign matter to float upward and thus produce perfect castings. This feature works equally well when the pot is quite full and the pouring spout 22 is high in the funnel as it does when the pot is nearly empty and the spout is low.

l rates 26 and 27 are preferably arranged at the ends of the receptacle 2() being bolted or otherwise secured to the standards 5 and which are designed for retaining the heat beneath the receptacle and thereby facilitate the rapid melting of the metal which is to be used in pouring the casting. It will thus be seen that the funnel 223 may be arranged in close relation. to the metal vessel 20 so that when the vessel is begun to be tilted the spout 22 thereof will pass immediately into the funnel through the slot 24 therein and thus avoid all possibility of any spilling of the molten metal.

It will thus be seen that a strong Simple apparatus is provided and one in which the platens will be gravity held in position for the pouring of the metal avoiding the necessity of using any auxiliary fastening means for this purpose, and which provides also for the retention of the back or upper plate in upright position when separated from the lower plate.

Vithout further description it is thought that the features and advantages of the invention will be readily apparent to those skilled in the art, and it will of course be understood that changes in the form, proportion and minor details of construction may be resorted to, without departing from the spirit and scope of the claimed invention.
