f2. A truck for single' truck street railway eers comprising side frames, pairs of Wheels journeyled neer the respective ends of, the trdclr, between seid side iframes, end brakes comprising luid pressure cylinders supported et .intermediate points on, and pro ecting inwerdl'f from the' liespective side rames, o poseo. pistonsltted 1n. said cylinders, brake s ces supported in braking relation to the Wheels end piston rods connected et their respective ends to the pistons end with the cesser.

brake shoes, but free from confinement between their ends.

3. A truck for single truck street railway cnrs comprising continuous side frames rig'-v idly connected together et their ends, pairs or" wheels between the side frames, journeled.

'the Wheels, brake cylinders mounted 'upon the side frames et points intermediate of the rods and having connections through which duid pressure is sup lied, and projecting ine Wer-diy from said si eflen1es into the planes of the yWheels, opposed pistons in seid cylindcrs, end piston rods connecting the respecu tive pistons directly with the brake shoes.
