The drill has a 4½-inch column and will swing 20 inches on face plate, which is 14 inches in diameter. The sleeve and face plate can be raised or lowered by the handle shown on engraving; it being accurately balanced by a weight inside the column. It can be changed very easily and in a very short space of time. The spindle is of steel and is held in arm that is made to swing over the same as a planer-head, so that work can be drilled at any angle required. The table swings around the column, and also turns on the sleeve if desired, so that it will drill at any point on the face plate without moving the work on it. The drill is provided with a screw-feed, or hand wheel, which has a brass nut, and the spindle is connected to the screw with a brass cap-nut. The gears are cut, both spindles and screws are made of steel, and the sleeve is made to fasten with handle by clamping to column. The drill has, in connection with the screw-feed, a lever feed for small quick drilling and countersinking, by which, for many kinds of work, double the amount can be turned off than with the ordinary screw feed. The drill is provided with counter shaft, pulleys, hangers, belt-shifter, and hanger-plank complete, ready to attach as soon as received. Great pains have been taken to produce a first-class tool, so arranged as to give great strength and accurate work with simplicity and ease of handling, and this, with an economy of cost which will be appreciated. |
