Lo pneumatico delle ruote per l'estrazione dell'orecchio è stagnato a circa la stessa sezione dellecome le rotaie in uso sulla nostra linea. Questo impianto è destinato non solo allo scopo di esperimenti scientifici, ma anche a fare awaywith i viaggi di prova di motori nuovi e riparati sulla linea principale.ha.s, quindi, è stato necessario renderlo rapidamente regolabile motori Itake con ruote di centri diversi. Il letto principale è provvisto di una cremagliera, al centro di ciascuna coppia di cuscinetti, dotata di un albero trasversale avente

The tire of the ear-rying wheels is tinned to approximately the same section on thetread as the rails in use on our line. This plant is intended notonly for the purpose of scientific experiment, but also to do awaywith the trial trips of new and repaired engines on the main line.It ha.s, therefore, been necessary to make it rapidly adjustable Itake engines having wheels of different centres. The main bed isprovided willi a rack, mid each pair of bearings is provided with across shaft having a pinion at either end. These cross shafts are driven ti I longitudinal shaft through suitable clutches. This longitudinal shaft is operated by electric motor and is capable ofbeing reversed. The engine is run over the machine on an ele-vaied frame which carries ii on the flanges of it.s tires clear, elec-trically, and drops 1 lie engine into position on the carrying wheelswith their healings till they an vertically underneath the wheels. i ii.. :;.—front view as si.hum. head grinding bevel cutter.

On this bed five pairs of bearings are arranged toslide longitudinally so that they may be adjusted for any centresof wheels that are to be put upon the plant. In these bearingsaxles are carried having wheels fitted with steel tires, on which thelocomotive runs. These axles are also fitted with drums on whichband-brakes act for absorbing wholly or in part the power developedby the engine. Outside these band-brakes, pulleys having an 18-in.face are provided at each end of the axle for driving link belts, bywhich it is intended to transmit the major portion of the power de-veloped by the engine to air-compressor
