Machine Supports. The fewer the number ofsupports the better. Heavy frames, as of large en-gines, lathes, planers, etc., are best made so as to restdirectly on a masonry foundation. Short frames asthose of shapers, screw machines and milling machines,should have one support of the cabinet form. The useof a cabinet at one end and legs at the other is offensiveto the eye, being inharmonious. If two cabinets areused provision should be made for a cradle or pivot atone end to prevent twisting of the frame by an unevenfoundation. The use of intermediate supports is. GENERAL PRINCIPLES OF DESIGN. 19 always to be condemned, as it tends to make the frameconform to the inequalities of the floor or foundationon what has been aptly termed the caterpillar prin-ciple. A distinction must be made between cabinets orsupports which are broad at the base and intended tobe fastened to the foundation, and legs similar to thoseof a table or chair. The latter are intended to simplyrest on the floor, should be firmly fastened to themachine and should be larger at the upper end wherethe greatest bending moment will come. The use of legs instead of cabinets is an assumptionthat the frame is stiff enough to withstand all stressesthat come upon it, unaided by the foundation, and ifthat is the case intermediate supports are unne-cessary. Whether legs or cabinets are best adapted to a cer-tain machine the designer must determine for himself. Where two supports or pairs of legs are necessaryunder a frame, it is best to have them set a certaindistance fro
