"The casting box; may be of any. preferred construotioni I In'the present instanceit 'is' composed" of an upper and a lower platen; designated 'generall y' by 5 and 6. The lower platen is rotatably oonnected-bymeans; of. bolts 8 sothat it may be swungbetween an open and= a-'c 1osed position andpermitjthe ready. placing of the: matrices and gauges.

The supporting rods are pivotally mounted on the frame at 24 i and on the cradle at 26. The guide rods are posed casting-box andstop' 36 being placed to hold the melting pot in its normal position over the burnerand clear 'of the casting box; The flow of metal from the pot is controlled from themlever 28 mounted on the melting pot and attached to; a plunger in the spout 32 through the link 30. The Weight 31 is placed on theend ofthe; lever to cause it to return to the closed position when released. v i

Any suitable means may beused for heating the melting pot such as gas, oil, and electric heaters. I have shown an oilv burner generally designatedby v34:, resting upon a bracket or shelf 33 attached to one end of the frame. Itthus rests directly under the melting 'potwhile the latter is in its heating position supplying the heat necessary for melting and 'maintaining the metal inlthe proper condition for use.

The operationof'my improved casting ma chine is safe, convenient and easy, Fig. 1

shows .the normal starting position with the:

casting box open and the melting pot-being heated over, the burner. In practice it is necessary for the operator to first cast a blank or slug to heat up the casting box. The slugis permitted to cool and is returned to the melting pot. The operator should then ar-' range the matrices and gauges upon the lower platen in theiusual manner, lower the upperv platen, clamping it securely in place, and then shift the casting box from its h0rizon-' tally disposed position to a vertically disposed position for casting, where it will be firmly held by the latch 37. v The melting-pot should thenbe swung-fromits heating, posi tion over the burnerto its pouring position over the vertically disposed casting box. A

stop on the frame is provided to prevent-the: melting pot from going beyondthe proper position for pouring. The operator may. then pour the cast by depressing .thelever and. permitting the molten metal to fill the casting box. Reversal of the operations will bring the machine back into its originial position for removal of the stereotype plate.

It isvevident that the operation of my improved machine is simple, that, but little special training is required of the operator, that due to the bottom pouring pot molten metal is not handled directly with the attending tom p'ouringmelting pot, supporting rods for. Y
