The flat turret lathe, the invention of James Hartness, of the Jones & Lamson Co., is shown in Fig. 251. Its principal feature is the large, low, flat turret, which, with its accessories, is covered by several patents. But other details, including the automatic grip-chuck and the roller-feed, are also entirely novel. The capacity of the lathe may be inferred from the following dimensions: 2 1/8 in. hole in spindle; working length which can be turned, 24 in., which, however, can be increased to order to 36 in. or 40 in.; working diameter, when worked from the bar, 2 in.; swing over bed, 16 in.; swing over apron, 14 in.; width of belt, 3½ in.; diameters of cone pulley, 10½, 8¾, and 7 in.; diameter of turret, 16 in.; length of bed, 6 ft. 8 in. ; counter-shaft pulleys. 12 by 4-in. face; shipping weight complete, 3,600 lbs. |
