One of the recent improvements is theplacing of the tool-room equipment on araised platform or balcony at one end ofthe machine shop, access to which is bymeans of a cast-iron spiral stairway. In-cluded among the tools is a tool grinderwhich has been improved by making thevertical movement of the tool head overthe face of the grinding wheel entirelyautomatic. This was accomplished byremoving the hand lever used for the pur-pose, and replacing it with a crank mo-tion to actuate the head, largely increas-ing the efficiency of the machine. The tool room is directly under this bal-cony, which made necessary some con-venient device for elevating and loweringtools between the repair point and placeof storage. A little elevator operated withair was devised for this purpose, consist-ing of a 4-inch pipe extending from thefloor, on which travels a small table ortray that is guided by three wheels; the.

A piston fitting the pipe is connectedto the elevator table by means of a steelcable which passes over a sheave at thetop of the pipe. The piston is weighted,and in operation an application of airforces it up, thus lowering the elevator;while exhausting the air from under thepiston allows it to drop by gravity andraise the elevator with its load, which isalways less than the counterweightedpiston. This arrangement of raising andlowering is seen to be directly oppositeto the general conception of such system of heating feed water andsupplying the shop boilers is in successfuluse here, in which the exhaust systemfrom the shop engine and also from theair compressors is taken to a series ofheaters located directly in front of theboiler battery.
