. The present invention relates to centrip-.

etal engines, the primary object of the in ine of this character, in which the rotor is provided with 'a plurality of tangentiallydisposed pockets, the inner ends of which terexhaust ports,

- pocket a'pluthe outer ends of *whicharedisposed to= ter-' of the rotor while the innerends terminate at a point to pror vide a clear and open exhaust port.

LA furtherobj'ectof the presentinvention nelof this hara'cter, the stator of whic is composed of having oppositely disposed exhaust channels leading from the center thereof and a plurality of tangentially disthere being disposedin ear:

\ posed induction ports, ,while the rotor is ve'ntion is the -provision of provided with a plurality of radial'pockets into which are insertiblc packages of spacedblades which constitute an impact and steam directing means to direct the steam led thereto through the induction ports to centrally jdisposed exhaust ports of the rotor and finally into the oppositely disposed exhaust ports of the stator.

A still further object of the present in-,

a novel construction of rotor and blades, said blades being soconstructed andarranged, as to be readily 40.

introduced into and removed from the tanential pockets of the rotor, said blades 'be-- mg so constructed as to permit'ofgthe greatest im act surface, and at the-same time proexpansive ----5+theLdetails 5'5 scribed and claimed, it being understood vi e means for-splitting. the stream of steam or other pressure fluid into minute-streams, so that'the maximum amount of impact and forceffrom the steam willresult prior to the'e'xhausting thereof from the central portion or the rotor.

J With the foregoing and otherrobjects 1111 view which will appear as the description proceeds, the invention resides in the. com? ination and. arrangement of parts and in of construction 'hereinafter deof which the fol- "of blades per se.

disposed as tothat changes in the precise embodiment of the invention herein disclosed-can be made within the scope of what is claimed without departing from the-spirit of the invention.

In the drawingsFigure 1 is a side elevation of the main. portion of the engine one-half of the head being removed to show a portion of the rotor in elevation; Fig.2

is a section takenon' .line- 2-2 of Fig. 1.

taken on line 3-3 of Fig.-

Fig.3 is a section 4. Fig. 4 is a section taken on line '4t of Fig. 3. Fig. 5 is a .detail view of one bundle Referring to the drawings, the numeral 1 designates the stator which is composerl of lower'member 2 and the upper member'3, said members, being properly coupled togetherto provide a steam tight joint therebetween, each' of saidmembers being provlded with two steam induction ports 4, wh ch are disposed ata tangent to the inner per pheral wall of the rotor chamber 6, which is preferably made cylindrical in shape. ---Ledto the respective tangentially disposed induction ports 4-are the steam orpressure fluid conduits 5, there being four in the present instance.

, It will be noted that the induction ports 4:,

are narrowed when compared to the cross sectional area of its respective conduits 5, but that each is elongated approximately the full: width of the active surface of the "rotor R so'that the pressure fluid or steam'is properly conveyed to the periphery of the rotor-R so as to 'act upon the full active peripheral surface thereof, as will presently appear.

TherotorR is keyed upon and rotatable with the, shaft Tend consists primarilyof the three disks 8, 8 and 8" wh ch are properly tied together by means of the tie bolts 24:, the intermediate spiders 9 being disposed between the respective disks and so formed as to provide the outer curved webs 10 and 'theplurality of tangentially disposed blade .pockets 11 for the reception of the bundles 12 of steam receivmg blades,"the irfner ends of said blades terminating as shown to provide theexhaust ports 13 at the extreme inner ends of. the respective tangential pockets 11. The exhaust ports 13 register at all times with the oppositely disposed exhaust ports ;14 and 14-of the stator, therebeing two series of spiders 9, the disk 8 being so form a; central partition to prevent the passage of the pressure fluid toward the transverse center ofthe rotor.

Upon the outer face of each of the respective disks 8 and 8" are disposed the concentric packing rings 16, which have led theretothe ducts 17, whereby the. pressure flu1d admitted to theirespective tangential pockets 11 will normally tend to push the pack- 7 ing rings outwardly into contact with the "La-steam tight joint to prevent the passage of the pressure'fiuid directly to the exhaust 'ports 14.01 let or any back pressure fronr adjacent face of the stator and thus provide the exhaust. 1

The blades 18 are soconstructed and see cured together as to provide a pluralityv-of steam channels 19, said channels due to the shape of the opposite walls 21, 22 and 23 of the respective pockets 11 being tangentially disposed and emptying into the exhaust port 13, the tie bolts 20 being employed to hold the blades in such spaced relation and to permit of the ready withdrawal orinsertion of the bundle within its respective pocketll. t

Although the packages of blades have been illustrated with the blades having the planes of the body portion disposed tan-' gentiallyto the periphery of the rotor B, it is evident that the same may be-disposedin bundles with'their planes parallel to the faces of the disks 8, 8 and 8", it simply be ing to and embodying the present invention, provides a means whereby the pressurerfluid is received or projected into the respective blade pockets tangentially to the rotor pe riphery,and that exhaust takes place at the center of the rotor without impeding in any manner the rotation thereof.
