Simon Ingersoll, ol New York city, has taken measures to secure a patent for improvement in machinery for cutting bungs and plugs. The revolving cutter is operated m cam while cutting, but withdraws it very la- ! pidly when it has done its work. The 1eed motion which moves the slab or plank eut of which thebung is to be cut, operates the plank at intervals, between the motions of the cutter spindle, to the proper distance, for every plug to be cut.
