The open-side screw planing machine of which we give an illustration on this page weighs approximately 22 tons, and is capable of planing work 10 ft. long, 4 ft. wide by 4 ft. high. The advantages claimed for this type of tool by the makers, Hulse and Co., Limited, Salford, Manchester, are that, whilst being as stiff and rigid as an ordinary machine, it is capable of planing over double the width and of operating on large pieces of irregular form which are usually dealt with on a much larger and more expensive tool. Ease of setting is also an advantage of some importance. The machine provides three cutting speeds, namely, 20 ft., 30 ft., and 40 ft. per minute, by means of a gear-box with a constant return speed of 100 ft. per minute. The outer support for the cross slide shown is, of course, readily removable, and is furnished as an extra when desired. There are two tool-boxes on the cross-slide and one side tool-box. The bed is of box form, 15 ft. long, with wide ?at bearing surfaces, side strip and adjusting screws being provided for taking up wear, while the lubrication is effected by rollers. The table has T grooves planed out of the solid, and is traversed by a double-threaded steel screw of large diameter working in a long gun-metal nut. This also has provision for good lubrication. Other features of the machine are fast and loose pulleys with improved strap shifting motion; adjustable stops for regulating the length of the stroke and automatically reversing the motion;
self-noting variable and reversible feed mechanism operated independently of the table motion; massive upright of box form keyed and bolted to the bed, and having a wide face to give the necessary stability to the cross slide; counter-balanced cross slide and power mechanism for raising the latter; self-acting relieving motion to the tools on the cross slide during the quick return stroke of the table; counter-balanced side tool box: self-acting horizontally with hand horizontal and angular traverse; and machine-out gearing throughout. The independent self-acting feeds vary from 1/32 in. to 3/4 in. for horizontal, vertical, and angular planing.
