Universal Radial Drill—Fig. 1 represents a universal radial drill built by the Niles Tool Works, Hamilton, Ohio. A heavy, rotating column, mounted upon a long supporting sleeve, which is secured to the base-plate, carries a radial arm, which can be clamped in any position. The machine is driven from an overhead counter-shaft operated by bevel-gearing, and by a central spur-gear seen at the top of the column. This also communicates motion through tumbler-gearing to the screw, which is operated to raise and lower the arm by- power. Motion is communicated to the drill-spindle from the cone, which is strongly back-geared by means of spur-gears, a splined shaft, and bevel-gearing. The arm is in form similar to a box-girder and is in one piece. The drill-head is securely gibbed upon the arm, and is adjustable to any position thereon. It is also adjustable to any angular position upon its saddle. |
