Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
162 words
An apparatus for molding articles comprising a support for a mold having a cavity that tends to become die locked and a lidsupporting means, said lid supporting means being pivotably mounted relative to said support and having a lid pivotably attached to said support means to maintain a fixed distance between the lid and the lid support means at the pivotable point of attachment but with a variable attachment means at at least one other point to permit the distance between the lid and the lid support means at the other point of attachment to vary to place the pivot of the lower extremity inside and away from the lip of the mold, said lid having a shape that when in the closed position relative to the mold cavity would form a molded article that would tend to be die locked and a means for pivoting the lid support means relative to its support to effect opening and closing of the mold.
