Abstract

565,003. Bolt hole bushes. COLTON, L. H. Feb. 16, 1943, No. 17877/42. [Class 89 (i)] Bushes, for bolt holes in timber, plastic wood, soft brickwork, cement and plastic substances, are of a form suitable for production in automatic lathes, and have a conical head portion 1, provided with serrations, grooves &c. that will restrain the bush from turning after being driven into the hole 6. A neck 2 connects the head to a portion provided with toothed circular formations 3 divided by saw cuts 5 to permit closing in of the sections prior to insertion. The bolt expands these sections, driving the edges of the teeth into the sides of the hole, the reduced thickness of the neck facilitating this action. The bush is tapped throughout its length for the bolt. A modification for longer bolts has a full diameter cylindrical portion between the head and neck.
