UNITED STATES PATENT OFFICE.
ORANGE D. HUNTER, OF PLYMOUTH, CONNECTICUT.
IMPROVEMENT IN CO RES FOR CASTING METALS.
Specification forming part of Letters Patent No. 142,790, dated September 16, 1873; application filed July 19, 1873.
To all whom it may concern: becoming-cold I add about one-fourth part of Be it known that I, ORANGE D. HUNTER, rosin,finely pulverized, flour, or other adhesive of Plymouth, Litchfield county, Connecticut, materiahbut preferably rosin; then thoroughly have invented a Machine for Making Cores mix the parts together. It is then ready to for Metallic Castings, of which the following form into cores of any desired shape, and when is a specification: dried is ready for use. I
This invention relates to the making of cores I am aware that sand has been used before for metallic castings where a smooth inside in its natural state, with rosin,flour,&c., as the surface, square or other shaped hole is deadhesive material, for making cores; but in sired, as in'the clock-key and similar articles. this way a large percentage of the castings The object of my invention is to make a core are imperfect. that will not generate gas when the hot metal What I claim as myinvention is is poured into the mold, thereby saving the The combinationot' burned sand with an adnecessity of venting, and also producing perhesive substance, for the purpose herein defectly-formed castings without blow-holes or scribed. roughness caused by "cut-holes in the mold. ORANGE D. HUNTER.
1n carrying out my invention, I take con1- mon molding-sand and heat it to redness, or Witnesses: nearly so, (and by this operation the gaseous MILES L. PEGK, matter contained in it is expelled,) and after HENRY A. SEYMOUR.
