Universal Vertical Boring-Machine.—What is known as a universal vertical boring-machine. Fig. 2, is in some sense a misnomer, although it is a very useful tool. It is intended to bore both vertical holes and those which are inclined in a vertical plane. In one of the best forms, made by the Berry & Orton Co., there are three boring spindles, each of which has a movement of 24 in. back and forth in a horizontal plane and one in a vertical one of 18 in., and which can be set at an angle of 45° or less with the vertical. Each spindle, or any combination of two or of three, can be moved at once back and forth across the table by a hand-wheel in front of the horizontal bracket which carries them, and which is borne by a vertical clamp back of the table. Each of the boring spindles has a quick return, and is advanced to the work by a counterbalanced lever. The table to which the work is attached is made of glued-up strips of wood, veneered top and bottom with hard Southern pine, and may be of any desired length. It has on its edge a number of stops for duplicating work without the expense of laying out; and on the top a system of bolsters and clamps that take in 24 in. in width, to receive and fasten the timber that is to be bored. The table is mounted on a system of rolls 12 in. in diameter, and about 6 ft. apart, borne on uprights fastened to the floor. The motion of the table is by hand or power, through a feed-stand and shifting bar; the rate of feed by power being about 200 ft. per minute. |
