Appletons' cyclopaedia of applied mechanics: a dictionary of mechanical engineering and the mechanical arts . nd the point for which the combining-tube is pro-portioned? This is true of all injectors with fixed nozzles, so that the self-adjusting injector pos-sesses advantages apart from the ease with which it adapts itself to varying steam-pressure andwater-supply. Still, there are many localities where injectors can be worked under practically con-stant conditions, and for such situations the non-adjustable injector is well adapted; while the sim-plicity of this particular form, and the ease with which its internal parts can be examined andremoved, will doubtless prove strong recommendations. Although this injector has no lifting attachment, it can be made to lift water when once startedunder a head in the supply-pipe. This was illustrated by starting the injector with a steam-pressureof 22 lbs. per sq. in., the water flowing to it under 15 inches head, and then suddenly changing theconnections so that the supply was obtained from the lower tank with a lift of 3 ft., the injector con- tinning to deliver water under these conditions. This action is probably the same as that of a siphon,which will continue to work when once charged, but cannot start unless the pipe is first being a vacuum at some point of the delivery-tube when the jet is established and the injectoris at work, this acts in a similar manner to the long leg of an ordinary siphon, and the flow The Non-Adjustable Injector, with fixed Xozzles, in connection with a Lifting Attachment, Figs.
