In a recent issue the operation uf a wellknown type of Westinghouse electric aircompressor was explained, and as it waspointed out at the time, some means mustnecessarily be devised for controlling theoperation of the coniiiressor. that is. it steam compressor governors. Instead ofcutting off a supply of steam pressure thework of this governor is to disconnect anelectric switch for stopping the and to re-connect or to make anothercontact for starting the compressor. Thisswitch is opened and closed throughmeans of a piston and rod workingthrough an air cylinder, the arrangementof which and the cut out details afford apneumatic blow out of the arc so effectualthat coils for a magnetic blow out or com-plete cut-off of current is inmecessary. The electric portion is show-n at the up-].er end of the cut of this governor and is. FIG. 3. \ I];\V OF TYPE T G0\I:KN0K both compressors to break down at thesame instant. Under such a condition thebrake valve would be placed on lap posi-tion to cut the air pressure froiu the mainreservoir away from the excess pressuregovernor top, then if the coiupressorsstarted when the handle was placed onlap position and stopped as soon as thehandle w^as returned to running i)osition,the gage hands still being less 20 , the excess pressure governor is atfault and the handle .can be held on laplong enough to place a blind gasket inthe operating pipe.

The most familiar one of these is knownas the type J governor, the electric por-tion
