Car Bolster Lifting Device AN interesting labor-saving device used at the Chesapeake•^^ & Ohio shops, Huntington, W. Va., is shown in theillustration. It consists of a windlass (two forms of whichare illustrated) used for applying or removing car bodybolsters rapidly and easily and with greater safety thanwould be possible with ratchet jacks. The usual method ofperforming this work is to raise a bolster into place beneathtlie car by means of jacks, the workmen who apply or re-move the bolts being in more or less danger unless great careis taken in placing the jacks. The men shown in the illustration are Chesapeake &. Easy and Safe Method of Lifting Car Bolsters Ohio em])loyees who, among other labor-saving devices, havedeveloped the method shown for raising car body operation consists of lifting the bolster by means of awindlass within the car, the windlass chain passing througha hole in the floor and being fastened to the bolster. Opera-tion of the windlass will then raise the bolster into placebeneath the car where it is held finnly while holes are beingbored and I>olts apjjlicd. There arc no jacks to interferewith the work or by slipping endanger the workman whomay be under the bolster. Any form of windlass may beused, two of the more common kinds being shown in theillustration raising the holsters A and B. 462 RAILWAY MECHANICAL ENGINEER Vol. 96, No. 8 from the total elongation the elongation due to stress alonewas determined.
