Clinton, Iowa Attached print shows a new idea andappliance just completed and doing verysuccessful work at Clinton shops, cuttingthe time of grinding one superheater fresh emery is applied, the trouble beingthat the moment the motor was held theleast bit out of level, it would tip the ringand start it to jump and work its way off carried in tool room of various sizes totit all sizes of steam pipe rings, and allthat is required to change from one sizeblock to other is to remove nut on end. DETAILS OF DEVICE FOR GRINDING STEAM PIPE RINGS IN SUPERHEATER HEADER. header flat joint from four hours to onehour. Before this rig was made we sim-ply stood up in smoke box and groundthe two rings by hand, which was labori-ous work, and averaged four hours tocomplete one ring. The rig shown ismade from fs-inch boiler plate, punchedout as shown to lighten it, and two 1 Ms-inch holes located in frame to suit holesin header, which holes contain boltswhich hold the rig in place. In -the cen-ter of frame is screwed a piece of castiron 3 inches diameter and 4 inches long,with hole through it 1 13/16 inches diam-eter to receive sleeve which is held inplace by nut and jam nut. This sleevein turn has 1 1/16-inch hole bored in it4 inch eccentric. The 1 1/16 inch holereceives the spindle, one end to fit airmotor, and the other end has attached toit a knuckle joint and star with fourset screws to
