L'albero principale del motore, che porta, in aggiunta al volano, i due indotti, è supportato in due blocchi a cuscino pronti per il funzionamento. Il grande getto che, insieme alla sua matasul lato opposto della vettura, sostiene il telaio della protezione, èfortemente collegato al camion auto. È necessaria una grande resistenza, poiché quando la barra di acciaio blocca la ruota dell'auto si verifica un forte movimento di trazione. L'azione del parafango è stata spesso testata con manichee altre ostruzioni. Un ostacolo

. The Street railway journal . and the fields of the dynamos rest upon acommon iron base. The main shaft of the engine, carrying, in additionto the flywheel, the two armatures, is supported in two pillow blocks ready for operation. The large casting which, together with its mateon the opposite side of the car, supports the framework of the guard, isstrongly connected with the car truck. Great strength is here required, for when the steel bar blocks the car wheel there is a severe draggingmotion. The action of the fender has been frequently tested with dummiesand other obstructions. An obstacle striking the board beneath theplatform causes it, by means of the mechanism explained above, tothrow the guard board to the rails, and at the same time block thewheels. Thus the obstacle is caught by the board and carried along, and at the same time the car is being stopped. The revolution of thewheels then ceases, and the wheels are caused to slide, thus bringingthe car to a standstill in the minimum time. The guard was tested. DIRECT COUPLED RUSSELL ENGINE AND GENERAL ELECTRIC DYNAMOS. mounted on detachable iron stands, so that the armatures may be re-moved without lifting the shaft out of place. A test conducted by Frank A. Simonds, mechanical engineer, todetermine the engines economy in verification of guarantees, yielded the following results: Running Non-Condensing.Duration trial, 6 hrs.

The accompanying illustration shows a life guard embodying anumber of entirely new ideas. It is the invention of H. H. Hennegin, 306 Temple Building, St. Louis. The aim of the guard is not only tosave a person from being run over by a car, but also to stop the car ina shorter space than is possible with the ordinary b
