With the aid of a pneumatic lift one man can re-move the truck from a car or replace it in twenty minutes,and the ease and facility with which the work of cleaningand repairs can be made with the trucks and motors sepa-rated from the car as compared with the time required todo the same work w itli the motors under the car, is not com-parable. A sim[)k and inexpensive lift may be made in your ownshop, as illustrated in the accompanying F-S 1 AIR HOISTS. Fig. I is an end view of a repair pit fitted with pneumatichoists for lifting the car bodies ofif the trucks. In construct-ing this hoist four air jacks are used, only two of which showin the end view. A, A are the rails of the tracks on whichthe car stands. The jacks are placed just outside the railsand pit frame, far enough, however, to allow the journalboxes or other projecting parts of a truck to pass when thepistons of the jacks are raised. The construction of eachjack is as follows: B is 4-ft., length of extra heavy wroughtpipe 8 in. in diameter. This pipe is threaded on both endswith a cap F over the top and a floor plate G at the is a piece of pipe 4 ft. 3 in. long and 2^ in. in diameterwhich forms the piston rod. It is threaded on both endswith a cap D at the top end. The piston E is made of twopieces of iron with a leather cup between them. The topplate of the piston is a 2J/2 in. flange screwed onto the rodand just fi
