CHARLES W. DAKE, OF CHICAGO, ILLINOIS, ASSIGNOR T0 PYLE-NATIONAL ELECTRIC HEADLIGHT COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF NEW JERSEY.

ca'go, 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 turbine, and is illustrated diagrammatically in one form in wherein Figure 1 is a transverse section; Fig. 2a longitudinal section along the line 22 of Fig. 1; Fig. 3, a detailed section on an en larged scale along the line 22 of Fig. 1.

Like parts are indicated by like letters in the drawings.

The turbine case A is provided with the base A which may be attached toany suitable foundation in any desired manner. The bearing sleeves A A are centrally disposed on opposite sides of the case A and the exhaust passage A on one side thereof.

The disk B is mounted on the shaft B which rotates in the sleeves A A and carries the annular" cage B which is provided with the passages B B inclined to the tangents at points along its periphery. The cage B? carries a plurality of flat annular pocket or channel disks B B each having the upwardly bent peripherally arranged flange B to form pocket or channel bottoms and sharpened inner edges 13 B The pocket or channel disks are so arranged between the cage B and the disk B that the annular flanges on the pocket disks operate as spacers and each flange presses against the adjacent disk. The flange B5B are the accompanying drawing,

perforate at 13 B in opposition to the pas-' sages B B. r

The nozzle C is carried on the case A and is provided with the passage G communicating with the supply pipe C and dis charging into the expanding delivery passage C in opposition to the sharpened edges B on the disks B B at an angle to the radius and sharply inclined to the tangent. By being sharply inclined to the tangent at the point where the stream of fluid or the line of its progress intersects the bottom of the'pocket or channel, I mean only to indicate such a departure from parallelism with the radius as will be adequate and proper to induce the rotary motion of the rotor.

This, of course, will difier according to design. The nozzle E, which is also supported by the casing A, is pointed in the opposite direction, but is in every other respect iden; tical. It operates as a rev ersing nozzle The supply pipe G which leads to the.

nozzle C, is controlled by the valve D and? the supply pipe which leads to the reversing nozzle E is controlled by a similar valve not shown.

It will be evident that while I have shown in my drawing an operative structure, many changes might be made in the size, shape and arrangement of the parts and in the way they are fastened together without departing materially from the spirit of my invention.

The use and-operation of my invention are as follows: In starting the turbine steam is admitted through the supply pipe into the inclined expanding nozzle. As it discharges or passes through this nozzle the steam expands with an accompanying increase of velocity and is discharged into the pockets or channels between the disks. The steam is directed by the nozzle outwardly at an angle to a radius and tends to impinge upon the bottoms of the annular pockets or channels.

The steam is arrested and deflected from its course by the bottoms of the pockets and banks up therein and thus the pressure of the steam in these pockets ismaterially increased. The inclination of the nozzle tends to cause the steam to assume a rotary or spiral motion about the axis of the rotor and the friction of the steam onthe walls of the pockets causes it to carry the rotor with it. The increased pressure in the pockets adds materiallytothe friction of the steam -and thus increases the rotational efi'ect.

The pockets are perforated at their hot: toms and the cage in which they are carried lao is perforated, the latter perforations for convenience being large enough to overlap and thus register with two perforations in the pocket bottoms so as to permit such water of condensation or other deposit as may be made from the fluid to escape. In

the particular form which I have shown, this is important, because otherwise, under some-circumstances at least, there would be a. tendency of the pocket to fill with water, moisture or other substances and this might, and in some cases would, interfere with the action of the device. On the other hand, if the inlet is placed in the periphery of these pockets, their bottoms being on the inside, and if, as would. be necessary in that case, the fluid should be discharged toward the axis of the rotor, such water or other deposit would be thrown out by centrifugal force.

I have illustrated and described my invention as used in connection with a turbine run by steam, but it will be quite evident that the entire apparatus is equally well adapted for use in connection with other motive fluids. lVater might be used with the same result, or the hot products of combustion might be discharged from an explosion chamber, and in fact my device is particularly well adapted to use in connection with such an explosive turbine, owing to the simplicity the lack of angles and projections and the comparatively thin extended surfaces. The over-heating which, when any turbine is'used in connection with burned gases, is present and disastrous, would here be of but small moment.

I thus by my arrangement provide a device in which the motive fluid is fed down-. wardly and toward the periphery of an annular flanged rotor wherein the elastic fluid is banked up and the pressure increased to increase the friction. between the flanged rotor and the elasticfluid so as to insure that the rapidly moving current will impart its velocity to the, rotor and will subsequently, as it loses its velocity, be returned back toward the axis of rotation and there discharged. k

I have used the term sulmtantially closed referring to the peripheral closure of theannular channels. This term I have used in view of the fact that the comparative small openings for the operation of the draining off the water are so small and the action so rapid that the escape of steam 's negligible. The truth of the matter is t at the steam which escapes, if at all, will be negligible and the ordinary path'of the steam will be into the deep channels and thus out toward the center.
