Fitting Sewing Machines for Steam Power. By a Singer Machinist.Unless carried out by trained engineers, the fitting down of machines to run by power of any sort is frequently very badly done. The need for some definite directions upon this subject by sewing machine mechanics is strikingly apparent, for, however clever many of these hard-working men may be in their legitimate employment of adjusting machines, they are apt to be " fogged '' when called upon to fit up a large stitching-room with various makes of machines, all to run by power, possibly at varying or various speeds. How to Lay Line Shafting.—-We may first consider a case where an unbroken line of benching and machines, possibly a duplex bench, extending to a length of 50 feet, must be laid. It will be seen that this case will tax the abilities of even a good fitter of shafting, for if everything be not perfect and true, such a line will require tremendous power to move it. The bearings will become hot, and it will be impossible to keep them cool, and the various couplings and junctions will soon work themselves loose, resulting in the ultimate breakdown of the whole line, possibly at several points. How different from this is the well-laid shaft, as straight and true as line and level can make it, that can be moved freely by the effort of one hand, and in which all the bearings keep as cool as any other piece of metal in the room. The first thing to consider is the position required for the shafting. We may suppose that it is intended to run the length of the room, and occupy the middle space.
