To all 'whom it may concern: l
Be it known that I, JOSEPH L. PRESBREY, of Tanmoxnin the county of Bristol-and State of Massachusetts. haslejnvented au 'Inmroy'ed Apparatus for Molding Urnciblcs; and I d6' hereby declare the saine to be fully described in the following speciiication, and represented in.
theaccompanying drawings, ot'which-f- Figure l is a front elevation,.Fig. 2 an edge view, and Fig. 3 a vertical section', cf it.
In the said drawings, A represents a mold as formcdin two equal parts, d b, provided with flanges e e at their edges for connecting thexn pendsand hangs withinthe matrix of the mold. y
After the Crucible in a state approximating to the shape of the mold, and in a condition'.
for being pressed, may have been introduced into the mold,- and thel coverv and two halves" .of the mold in ayhave' been fastened tcgether;
air, water, or st'eani is to be.int'roduced and forced into the elastic bag,ror bulb, soasto" dilate, or lexpand it suicieutly hto cause itx. to crowd the plastic material or" composition of which the crncible may consist hard up against the inner surface of the mold, after which, on suffering the air, water-,or steam to escape from the bag, such bag will collapse to its normal condition, and on separating the sides and' cap of the moldwe shalln'd the Crucible pressed into the desired shape.
Iclaim-v f Y The combination and arrangement of the elastic bag and the crumble-incid,substantially asdescribed. l y 'JOSEPH'. L.' PRESBREY.
