NCH STOCKBRIDGE CRANK SHAPER This i6 in. back geared shaper for toolroom work, or as aproductive shop tool, has been designed with the idea of meetingall the requirements of up-to-date manufacturing, and to thisend a heavy, rigid machine weighing 2,850 lbs., has been the regular characteristics of Stockbridge Shapers, thismachine embodies several new features designed to add mate-rially to its productive capacity. Among these is the column ways on which the cross rail method of attaching the cross rail to the column is new inshaper practice, though long employed in milling machine de-sign. With this construction one gib is cast solid with the crossrail, which in addition to increased stiffness, prevents any possi-bility of the rail tipping away from the column when the adjust-ing gib, which is on the working side of shaper, is this construction no time is lost in going around ma-chine to tighten and unloosen binder bolts every time the cross. AN INTERESTING 16-IN. CRANK SHAPER rail is lowered or raised, which is necessary where two loose gibsare used. By simply tightening the gib binder screws on theworking side of shaper the cross rail is locked to the column, asimilar construction to that of a milling machine. It will be noted that the rocker arm is of special design. Theslide ribs are cored U shape, making an exceptionally strongconstruction, and the slot in the rocker arm is of unusual depthand width to provide ample surface for the crank block. Theram is carried around on a semi-circle on the top and the sidesare built straight down. This construction, together with inter-nal ribbing, gives an unusually strong and stiff ram. The head,which is accurately graduated, and can be adjusted to any angle,is locked in place by two bolts, one on either side. For takingup the wear in the ram ways, tapered packings are provided,which run the entire length of column and are adjusted frome
