Stirling boilersfrom this companys Vineyard power plant to a newpower plant at Torrance constructed to serve the carshops under erection at that point. When the occasionarose for the removal of these boilers it was at firstthought to be impossible to remove each one complete,as each consists of four 24-in. drums with numerous3-in. connecting tubes. The cutting of the tubes con-necting the four drums was considered and it wasestimated that it would cost approximately $3,000 toremove them and to weld them in place. A contractorhowever, successfully carried out this work withoutdismantling the boilers, with considerable saving intime and expense. In carrying out this work each boiler was first re-leased from its permanent position on the brick founda-tion, and the bolts used to hold the steel frames in place. were removed. The rear end was then elevated tothe same level as the front, and after cribbing had beenset up the boiler was moved on rollers across the steammains, but without touching them, and over additionalcribbing to a point opposite the door. This door wasin the side of a concrete wall of the power plant, andit was necessary to enlarge it to 4 ft. jamb by 101 A donkey engine located on a flat car outsidethe power plant was used to tow the boiler by meansof a cable line. Planking was placed on top of thecribbing as a surface for the rollers. The maximumheight of the cribbing units was lOi ft. When the boilerhad been brought to a point opposite the door it waslowered by removing the sectional units of the was then turned at right angles to the door, andmoved on rollers and skids outside the building. Hereit was again moved by means of rollers up an impro-vised timber incline over an 8*-ft. retaining wall ontoa steel flat car which
