A Wonderful Planer.

A masterpiece in mechanical construction lias been built in Glasgdw, a vertical and horizontal planing machine, for the use of marine engineers and others, when ordinary planing machines are insufficient. This machine consists of a heavy bedplate of a box section, forming the work table, and carrying, when desired, a set of compound slides, and circular table, the motions of which can he made self-acting. For horizontal planing, the vertical column, which carries the tool, is driven by two horizontal screws connected by bevel gears; and, in vertical planing, the tool is traversed up and down this column by a vertical screw, driven by a bevel gearing below; the driving nuts which run on these screws are very long and completely envelop the screws, thus having ample wearing surfaces; the tool saddle is balanced by a weight inside the column, supported by vertical chains, and automatic and hand feed are provided both in the case of the saddle and column. The driving is effected through two sets of pulleys, the smaller giving the quick return motion after the cut, and the belts are so arranged that one belt leaves the llrst pulley before the other begins to drive, thus reducing the wear of the belts. The change of ’driving from vertical to horizontal can be effected instantaneoulsy.
