STERE'OTYPE CASTING MACHINE Filed Nov. 16, 1928 ator 'to n the castingbox. The blank is permitted' to construction which may be seen to offer distinct advantages. A vertical standard 14 is fitted at its bottom end with a connecting member 15 having sockets into which are set legs or feet `16 and a cross member 17. The cross member terminates in a second connecting member 18 which is supported by an u right 19`with a oot'20 at the base. rhue t .e frame consists of an uprighthaving two sta-` bilizing legs at its base and a single offset leg connected by a horizontal member. Trun-l nions 21 on the lower platen .of` the casting box are journaled in the two connecting' members holding n v axis at right angles to the vertical member 14.

The melting pot generally designated Eby 22 rests in the cradle 23 which is rotatably mounted on the vertical upright 14 so as to: be'eapable' of being swung through an rv angle ofi180 between a position convenient for heating and a pouring position as shownfin Fig. 1. The side of the cradlevbearing. 26y iS slotted at 24 to receive a pin 25 passing through the slot and set into the vertical upright to act as a stop and prevent the pot from being rotated beyond the vposition desired. The tlowlof metal is controlled from the'lev'er 27 mounted upon the melting pot and connected to al plunger-in the spout 28 bymeans of the link 29. The weight-30 is att/ached to cause the lever to return to the closed. position when released. g lha-ve used a novel. and positive means for preventing: the 'lever 127v from being `-accidentally.de-k pressed, thus making it safely possible'forV this lever to serve also asa^ handle orrotat-l in the melting pot from one position to -the ot er. The latch handle 31 vis attachedto thevhandle'of the pouring lever at 32 with a short end extending beyond the fulcrum. To this short end is attached they rod 33which is forked at its lower end 34. When thelatch is in the safety position thefork rests over' the projection 3K5'from the cradleso'that the pouring lever may'not'be depressed. The dotted 'lines in Fi 1 show the atch released and the lever rea y for pouring. i

The melting pot may be heated by any sfltble means. y,I have shown here' algas burner generally designated by 36 supported ony the meltin potcradle and supplied with gasthrough t e flexible tube 37.

'Theoperation of my improved casting ,malv

chineI isI easy and convenient. Fig. 2 shows V121e''normalstarting position, with the casting box open and the melting pot being heat# ed. In practice' it is necessary for the operf rst cast a blank or slug to heat up cool and returnedto the melting pot. Thev operator should' then arrange the matrices# and gauges upon thelower platen in the usual manner, lower the upper platen, clamp it securely in pla-ce, and then shift the casting box from its horizontally disposed posithefcasting box with its-y tion to the vertically dis sed position for casting. It will be held rmly in this position by the latch. The melting pot should then be swung from its heating position to the pouring position over the vertically disposed casting box. The operator may then pour the casting by raising the; latch and depress'ingl'the peurmg. lever.: Beyersn the operations will bring the machine bac to its normal position. It will be evident that the operations ymay ybe very easily performed. Thecasting box, may be easily swung from psiton't position because of its balanced ymounting.;The meltigg pot is simply rotated on its axis in a horizontal plane, very little effort being mquiredior theloperatn. In .addition no special skill is required of the. operator to safely Vcarry 1out the movements.: It mayV also befseen that my improved mai chine is free from many structuralJ defects. found in prior machines which have proved to be a source of danger unless handled4 with.
