Vertical Spindle Milling Attachment taper cones in opposite directions, adjusted by a nut on theoutside of the spindle. The base of the head is graduatedso that it may be set at any angle in a vertical plane parallelwith the elevating screw, and the attachment when clampedin position on the dove-tail slide of the column which ex-tends above the center line of the spindle, is as rigid as ifit were a part of the milling machine. AN AIR TIGHT SOOT CLEANER SWIVEL HEAD AN improved soot cleaner swivel head which providesfor easy and convenient operation, and does not leaksteam or permit air infiltration is shown in one of theillustrations with a part of the swivel head cut away toshow the relation between the steam delivered to the swivelhead from the vertical riser or pipe, and its entrance intothe movable horizontal element or spray pipe. The latteris fitted with steam turbine nozzles througli which steam atliigh velocity is sprayed upon the Ijoiler tubes, thus blowingoff soot deposits as
