Abstract

267,251. White, A. E., (Gould Coupler Co.). Dec. 23, 1925. Dynamos, driving; inductor-alternators. - A turbine generator set suitable for locomotive headlights and the like comprises as a unitary structure an alternating-current generator with a turbine wheel on the shaft, the steam supply to which is regulated by a centrifugal governor located adjacent the turbine wheel but which, with its controlling mechanism, is situated outside the path of the steam. The turbine wheel 34 is mounted on a tubular shaft 46 which slides on the generator shaft and drives through a key. A centrifugal governor 37. adjusted by a cap 95 on the turbine shaft 46, is connected to a valve operating lever 39 through an universal joint 38 consisting of hemispherical cups enclosing two graphite or carbon hemispherical members on the lever. The governor is housed in a separate governor chamber 35. The whole turbine structure is carried on an end plate 28 of the generator which includes a bearing housing 29 wherein a shouldered ring 44 retains a ball bearing for the tubular turbine shaft. To remove the ring 44 and its bearing, a bolt is screwed into a tapped hole 51 in the ring to abut against a stud 52 projecting into the hole. The pole-pieces 26<b> of the generator are formed with extensions 26<c> engaged by the ends of semi-cylindrical permanent magnets 27<a> under the pressure of springs 27<b>. Disc washers 55, 56 are fitted to the bearings to retain oil in the races.
