1 Application filed. Apri126, 1912. Serial No. 693,432.

' citizen of the United States, residing at Chicage, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Turbines, of which the following is a specification.

My invention relates to improvements in turbines, and is illustrated in one form in ,the accompanying drawings, Wherein Figure 1 is a transverse section; Fig. 2, a section. on the line S S of Fig. 1; Fig. 3, a diagrammatic view of the rotor rim with'the inlet shown on the dotted'line X of Fig. 1 Figs. 4 and 5, details;

Like parts are indicated by the same numvariation canbe. made in the ewe, shape,

her in all the figures. 1 is one side and 2 the other side of the rotor case; 16 is an opening intlie rotor case closed by the cap 17 which contains the inlet channel 15 and into which is screwthreaded the inlet tube 3. From the inner end of the inlet channel leads the inlet nozzle 14; at is the exhaust outlet; 5 is a shaft which passes through a central opening in one side of the case and carries at its inner end the rotor body 6 about the periphery-of which is'formed the ring 7 into which is secured in any desired manner the channel pieces 8' and 9. These pieces and the-ring .are spaced by and connected together through the diagonally placed spacing blocks 11 which are provided as shown with holes for both the screws; 12 and 13 are U-shape'd annular grooves formed by and between the channel. pieces and the ring. The nozzle 1% is placed so as to discharge the fluid at a sharp angle to the radius of the rotor, has

' diverging walls and extends beneath the here shown, and the body may be of any desired shape, although it is here shown as a Specification of Letters Patent.

disk. The ring and channel pieces together constitute the rim of the rotor. I-have shown two channels; there might be one or more than two. I have shown the connection between the exhaust and therotor as inadeat a single point by means of an over-hanging ,ledge, but of course the connection can be made in any desired way.

It will be understood, 01": course, that I have omitted parts which will have to be understood as present, for example, bearings for the rotor shaft,'that the parts as actually shown are not necessarily made in the exact -proportions and relations indicated, that some of them may be dispensed with and,

others substituted, and that considerable proportions and arrangements of the several parts all wlthoutdepartlng from the spirit of. my im'ention. The drawings are to be grooved and the edge of the ring inclined so as to "make each opening oi each groove larger in cross section than the body of thevgroove or channel.

The use and operation of my invention are as follows: Assuming that the parts are constructed and arranged substantially as indicated in Fig. 1, if a fluid under pressure, 1 for example steam, be introduced through the inlet, it will discharge through the expanding nozzle into the enlarged openings of the channels on one side of the rotor, will then pass inwardly through and diagonally along the two channels and across theperiphery of the rotor and for- 'wardly in the direction in which the rotor is moving from the inlet to the discharge 'pass out of the channels at practically no tor speed int the exhaust side of the case and thence into the exhaust. The streams of fluid will pass-0n both sides of the spaci side of therotor casing and will ultimately ing blocks which are: set so as to cause the least possible interference.v The fluid in be ing thus diverted from a direct passage through the channel or being directedagainst the curved Wall of the channel, will tend to have its pressure increased along or between the curved Wall of the channels. This, however, re-acts to-inorease the friction'on. the Walls of the channels and thus to transmit more thoroughly and completely theenergy-in the fluid to the rotor rim to causethe rotor to rotate, The fluid travels With the rim and if the parts are properly designed most of the fluid ill escape on the exhaust side ofthe rotor into the exhaust at approximately the. opposite end of the diameter of the rotor, at the otherend of which the fluid is admitted. Broadly speaking the'fluidsis fed into anarrow space between two surfaces or into a channel bounded by tWo surfaces, and these surfaces arearr'anged, as for exampleicurved, so as to deflect or divertthe current or currents of fluid from a direct course to an indirect course, thus arresting the forwardprogress of the fluid and diverting an increased fric-' 'tion for the purposes set out. The particu- .lar method of thus diverting or changing the direction of the current or-curre'nts of fluid on the passage through the open chan nel or channelsmay not be just What is here-- shown, but what I have shown appears to be an easy andconvenient method or apparatus for accomplishing this result.
