TEE-HE.\D. The placing of the tee-head in position in the smoke-box is a hard proposition for two men and an awkwardone for three on account of the restricted space. Withthe device shown in Fig. 2 the work may be done by one man with the help of an overhead crane. It is made of tworods E not less than 1 in. in diameter and formed as shownin the illustration. .

A chain, with an eye C for the cranehook is located about 5 ft. from the end of the device, and iswelded to the rods at A. The rods are held together at theend by a link D. With the lifting rods bolted in place thecrane hook may be lowered through the smoke stack andhooked into the ring C The workman can balance the wholeapparatus at D with one hand and signal the crane man withthe other, and in this way lift and fit the tee on the stud bolts.
