Perhaps the most important feature of grinding machineoperation is keeping the grinding wheels in proper smooth and accurate work the wheels must be , especially when grinding relatively soft metals,the grinding wheel surface becomes clogged and must bedressed. For this purpose the safety wheel dresser illus-trated is effective and always ready. It can be used frequently on account of the ease and safety of operation, thus keepingabrasive wheels in first class Pratt & Whitney Safety Grinding Wheel Dresser Safety Locomotive Feed Water Attachment SIMPLICITY of operation, the absence of threads, andall parts secured in position are three features of a newsafety feed water connection between engine and tender,recentlv patented bv W.
