The New Doty Combined Punch and Shear
Two forms of combined punch and shear have been bought out by the New Doty Manufacturing Company, Janesville, Wis. In the first, Fig. 1, there are two sets for flat iron and one for round iron, in addition to the punch. It is so arranged that the two sets for flat irons are each independent of the other and of the round iron knives, and all independent of the punch, so that either part of the machine may be used independently of any other, as may be desired. The machine can punch a 5/8 inch hole in ½ inch iron ad cut 4 by ½ inch iron or steel and 1 inch rod iron. The round iron knives are made the reverse of the iron and so do not flatten it in cutting.
If the other machine, Fig. 2, the knives for flat and round iron are independent of each other, and of the punch, and both sets of knives, as well as the punch, are at all times ready for use without any change. This machine is powerful built. The boxes are cast solid, and the eccentric shaft are also cast in one piece. The motion of the machine is controlled by a clutch and treadle. The stripper is adjustable to 0.001 inch and the punches and dies can be adjusted without stopping the machine. Before leaving the works these machines are tested to a strain in excess of that for which they are guaranteed. |
