30,063. — R. Hemingray, of Covington Ky., for an improvement in Molds for Glass Jars:
I claim the mold herein described, for molding such jars as have an annular groove, h, surrounding the mouth of the jar, consisting of the parts, D D, having an annular projection, i, for the purpose of forming the grooves h, so hinged or connected with the parts, A A, of the mold as to open upwardly, while the parts, A A, subsequently open laterally, thus releasing the jar from the mold and permitting the same to be removed without injury, substantially as set forth.
