alue is shown in the reamer forcleaning out exhaust nozzles. This too!is operated from the top of the stack—nofront-end door to open or netting to re-move. It is made very light—the body54-nch gas pipe, and the reamer end of■j&t X ^^-inch steel, with flexible blades.The tool is easy to handle and a goodthing. They have a device here for lining up guides, which reduces that operation toits lowest terms.and insures absolute truthin alignment of guides with the bore ofcylinder. The illustration shows a starframe with four arms, which are securedto the cylinder head studs at the front end.The gland shown has a tapered bodywhich fits into the stuffing bo.x of the diameter and length equal to the cross-head fit of the piston, and it is this ringthat tells at once, when the crosshead isin place, which guides need the liners, bymoving the ring to the crosshead andnoting its position with reference to thepiston fit.

Fitting into the bush and gland is aij4-inch round steel rod, and this rod hassufficient length to have a bearing in thestar and gland, and at the same time ex-tend to the extreme end of the guides tobe lined up. At the crosshead end of therod there is a sliding ring having an outer through a cylinder, that even a rough ad-justment with it gives a better alignmentof the crosshead and cylinder than thebest work in the old way; and, again,there is no fear of a line being moved orcut with this device. In a great many shops—too many—thetruck-wheel press and its surroundingsare hardly beauteous enough to inspirea lasting respect in the observer. A darkcorner, lots of grease, and blocking bythe cord, is generally the fate of this tool;and with that picture in the mental pla
