It is manufactured by theSpringfield Mauufacturins Company. Bridgeport. Conn. Wheels. Self Contained Car Wheel Grinding Machine of any diameter from 28 in. to 44 in. may be handled and pro-vision is made for centering journals up to 6 in. in machine is self-contained and is driven bv one belt, either AGE GAZETTE. MECHANICAL EDITION Vol. 89, No. 3 from a line shaft or by a motor mounted on the base. Thecotmtershaft is mounted on a frame which is placed in frontof the machine in order that the space directly above the centersmay be unobstructed. The axle is driven by a gap gear at the center from two driv-ing pinions which are widely spaced to overlap the gap in thedriven gear. Both pinions are driven by the same shaft in orderto insure correct relative action at all times. A clutch whichis operated by hand levers from cither side of the machine facili-tates stopiiing the axle accurately wlien the gap in the gear isproperly located to permit the removal of the axle. Three dif-ferent axle speeds are obtainable. The grinding wheel spindles are driven b
