Railway and locomotive engineering : a practical journal of railway motive power and rolling stock . -penter shop, on the boring mills, including the verticalhorizontal and car wheel and drill presses, in the erectingshop, fitting department and grinding room, by the key-way cutters and millers, lathes, laboring gang, millingmachines, planers, paint shop, slotters and wheel gang,and in the roundhouse, tank shop and tin, pij^e and coppershop, twenty-five in all, leaving seven drawers for futurerequirements. Bridge Tree and Stringer for Countershafts It is frequently necessary to supplement the rooftrusses or cross beams of the shop to support short lengthsof countershafting. As they say in patent suits, the bridgetree here shown is one that any mechanic, skilled in theart, would be capable of designing and constructing, andis illustrated merely as a good suggestion. It is shown as spanning a distance of 14 ft. betweentrusses. The horizontal member is 3 in. thick and 10 and is laid on top of the truss beams. This is a mereplank and would, of course, be quite too limber to carry. Bridge Tree /<? o nd Stringer for Countershaft any sort of a shafting hanger. The braces are of 3 in. by3 in. material and have a footing gained J4 in. into thehorizontal or tension member of the truss. The king pinis a ^-in. rod, and the height of the truss is 3 ft. 6 a truss should be capable of supporting a static loadof 4,000 lb. and Ije stiff enough to carry the lighter loadof any ordinary countershafting with its attendant vibra-tinns, Chuck for Holding Eccentrics on Boring Mill This chuck is intended for holding eccentrics on aboring mill while the outer surfaces arc being rer|uir(s that they be Ixired and the kcyway cut beforebeing f)laced on the chuck. As the eccentrics may be re-(|uired for different diameters of axles, the block A of thechuck is made removable, and there is to be one turnedand a keyway cut for each diameter of bore of eccentricthat i
