A machine of an improved character for cutting tin and sheet iron has been invented by Henry C. Hart, of New York City, who has taken measures to secure a patent. The apparatus, in its general features, resembles the cutting machine that is so universally employed by metal plate workers, but there are two improvements upon the original which require to be noticed. The bed on which the tinned or other plate is placed is hung in an adjustable lever so that its centre or pivot may be altered, and the work fashioned to a circle of any diameter. The frame which carries the shafts of the circular cutters is readily adjusted by set screws, sd that the cutters can be given the proper inclination, and also be elevated or depressed as desired.
