ToaZZ whom it may concern: Fig. 4, is a cross-sectional view through Be it known that I, SAMUEL P. GREENE, the sand mold and cores as arranged for a citizen of the United States, residing in pouring the metal. Dayton, in the county of Montgomery and Fig. 5, is a view of a flask, partly in State of Ohio, have invented certain new broken section, showing the manner of us- 55 and useful Improvements in Jackets for ing afiask as a pattern for the jackets.

By adding a bottom exthe rough usage which foundry equipment tension -3t-, to a flask 5, as indicated in receives, this latter difiiculty being also ex- Fig. 5, of the drawings, to compensate for perienced with sheet metal jacketswhich shrinkage of the metal in casting, the inside renders sheet metal jackets impracticable dimensions in length, breadth and taper of for general use as a substitute for wood the flask can be closely approximated in the 30 j k t 7 jacket castings made from it, the height,
The improved cast iron jacket of the thickness of the walls and externalco'nforpresent invention effectually overcomes the mation of the castings being determined by difficulties as it retains its shape and is pracusing suitable cores, as indicated in Fig. 4, tically indestructible under any conditions in preparing the molds.
