The governor may be located either under the car or in one endof the car. The electric apparatus above described is for direct motors and governors are being used to someextent, but have not yet come into very general use. Reservoir. The reservoir should have a sufficient capacity tosupply air for three or four applications without reducing the pressuremore than 15 pounds. It is conveniently located under the car, andits dimensions depend upon the size of the brake cylinder used. Itserves to collect moisture and oil, and prevents them from being 193 98 ELECTRIC RAILWAYS carried further into the system. It should be drained frequently,as its capacity for stored air will be reduced proportionally to thevolume of water it contains. Brake Cylinder. The brake cylinder shown in Fig. 92 is of thehollow-rod type. The piston is connected to the brake rigging in such. CylinderFig. 93. Section of Air Operating Valve a way that it moves only when the power brake is used. When thehand brake is used, no movement of the piston occurs. The pistonrod 1 is made hollow to receive the push rod. A leather packingring 2 is provided which prevents air from leaking around the leather packing ring is held against the walls of the cylinder bymeans of the round spring expander 3. The cylinder head 4 may 194 ELECTRIC RAILWAYS 99 be either plain or as shown. That shown is constructed to receivean automatic slack-adjuster- which is sometimes used with theautomatic system. When an application is made, air enters behind the piston andforces it outward, c
