Multiple Traverse Table-Drill.—This machine, shown in Fig. 3, is built by the Niles Tool Works, and is similar in design to the usual pattern of multiple drill, except that it is provided with a table arranged to slide upon the bed. Machines of this class are especially desirable when it is required to drill a number of holes in heavy pieced clamped together, such as vault-doors, etc. In work of this kind the separate pieces can be fastened together upon the table and any desired part brought under the drills. The spindles have 12-in. travel, and each has independent power-feed with three changes. They are also arranged for hand-feed, and each is counterweighted and" has quick return. The machine is capable of drilling three 1½ in. holes or two 2-in. holes at the same time through steel plate. |
