TURBINE.

` Application iled March 16,

compressing` the flui o avol ute case, within wh rotor is provided,l said laminatio The invention is illustrated bv ample in t which: i

Figure 1 is a viewin central longitudinal section through the structure.

ig. 2 is a view in central transverse section through the turbine disclosing tion ofthe volute oase'to i l Referring more particularly to the drawings, 10 indicates a volute This struc` ture is substantially circular, having an ine uction nozzle `11, and eduction passageways 2 and 13. By referring to'F" way'ofexhe accompanying drawings, in

of te case. v a and 13 cominunithe conoidal case cuinferential portion of i `case is which is a continuation arranged induction nozzle 11 and sageway decreases in sectional area as it Y Y within the case with its central transverse plane with the transverse `center of the conoidal case.

The rotor is mounted upon a i shaft19"disposed. eccentrically of the volute f of greater section than the reinainin `at eith is formed with which is beveled Huid to produce r The present invention contemplates-the use f 'ch a laminated ns bein@ `to insure that a `motive fluid will be made throughout the the fluid may take place as its tion openings 25 openings as shown in :increasing area toward 16 and into the eduction i will b axis in the saine 1921. Serial No. l52,650.

d receive e rotor itself is formed with a plurality of laminated disks. large turbines the central er side and which a throat 22, establishing communication between th Whichwill thereafter encounter the surfaces of other rotor disks.

n t e present instance three other sets of disks are shown as indicated at 23, 24 and hese disks are all formed with double fe edges and are arranged and designed uniform distribution of the kni rotor and that )ended and. as the fluid i travels toward educin each of the disks. These Fig. 1 are of graduallyr rotors and are the fluid pacing washers 27 tween the various plates and form the hub ofthe rotor. These washers and the plates `are secured together bv fasteners such as rivets 28 arid are hired to the rotor shaft 19. In 1 th so that the Slightly used as a generator a fluid is delivered to the nozzle 'll under high pressure and velocity. rl`his nozzle is tangent to the circumference ot the volute case and will direct the tluid into the volute passageway 17 which `gradually decreases in its sectional area. This arrangement will cause the gases to pass through the annular throat 22 leadingfrom the passageway 17 to the main chamber of the casel it is divided into various streams which .pass between the laminations of the rotor. t is intended that the laminations arranged as tc equally divide oi' `fluid passing therebetween. but it this does not lexactly occ-ur7V equilibrium may be established by the passage ot fluid through slots Q9 in the disks. rlfhese slots are 'formed with substantially radial lrnite'edges which will oiler slight Vresistance to the fluid as it `passes through the dislr. Eis-shown' in the drawings, sets ot these slots' are arranged in alignment along diilerent. circles yon the disks. The passage of the fluid between the glates will cause a rotation ofthe rotorin vthe direction ot travel of the fluid which. rotation will be imparted to the shalt 19. The ll'uid may then pass 'from thecase through the eduction passageways l2 and lf3. lf the vturbine is to be used as apump or a conipressor the rotor 19 is driven at ot' speed, and will act to impart motion to a fluid drawn in the rase, which fluid will be yenpelled through the tangential nozzle vl1.

lt'will thus be seen that the turbine here disclosed, while otsiinple construction, yet provides eilect'ii'e means tor obtaining power from a motive luidor tor imparting motion to a liuid.

While ll have the volumes shown the prei'erred torni ol. my invention as now known to me it wil be understood that if'arious changes might be made in,the combinationa` construction and arrangement otl parts by tho-se skilled in the art, without departing` from the spirit of the invention` asclaimed.`

Having thus described my invention, what .l claimand desire tosecure bylictteii's Patent is: i
