The Goldblatt No Turn Handle

US Patent 2,076,836

An old and very worn plastering trowel found at a flea market, after cleaning, was revealed as a Goldblatt No Turn Handle. Louis I. Goldblatt was granted US Patent 2076836 on 13 April, 1937, for an innovation in plastering trowel handles. His design turned the aluminum handle mount into a fin, cast integral with the rib and post. The wood handle had a slot cut into the top to receive the fin. The patent drawing shows a small wood screw through the end of the fin and into the wood. As manufactured, the wood screw was replaced by a machine screw completely through the wood, countersunk at its end. Lettering cast into the rib on both sides identifies the trowel:
