ROTARY WATER MOTOR. No. , February 26, 1895. Columbus K. Rogers,Salem, Mass., inventor. Figs. 11 and 12are respectively longi- by side upon a common base, which shape causes the partitionto closely conform to the shape of the motor wheels. Thepartition Bl is provided with two series of ejector nipples thatproject downward at a tangent to the two wheels, the nipplesof both series being inclined in the same direction so that thewheels will be rotated in the same direction. From the centreof the partition B* depends a division wall, Bf, that extendsdown to the motor shaft g and separates one motor wheel fromthe other and prevents any back pressure on the blades of thewheels, and also prevents any water ejected against one of the.

The chamber E is connectedby means of a pipe, e, to any suitable source of water water from the pressure chamber E is forced through aseries of ejectors B B against the fans or wings d d of thewheels I) D, thus causing the latter and their shafts to be setin a rotary motion. INJECTOR. No. 534,194, February 12, 1895. Robert Grundy Brooke, ofBlackpool, England. This is an improvement in what areknown as combination injectors, in which several boiler fit-tings, usually separate and distinct from the injector, are com-bined in the one apparatus. An object of this invention is toconstruct an injector of the type referred to in such a manner 192 THE AMERICAN ENGINEER [April, 1S05. that it can lie conveniently fixed t i any part ol the boiler, and sothat its various parts can be more conveniently taken apart than has hitherto been usual. For this purpose tin injector is constructe
