Specification of Letters Patent. i Patented M313 26, 1912 Application' filed September 22,1908. Serial No. 518,925

' the common axis of the three heads. The

frame has a foot 12` extending downward fromthe lower beam 11 near the head 9, while at the other end of the frame a tube 13 extends transversely under said beam 11 60.

and adjacent to the lower portion of the head 7, and afoot 14 projects from each end of saidtube. The tube and all the feet are cast integral with the rest 'of the frame.

'It will thus be seen thatl the frame has three 65 I points of support which minimize the effects ofdistortion from any cause. The feet 14 are sufficiently widely spaced to prevent the frame from rocking sidewise while the posilt-ion of the foot 12 prevents-movement in 70 a. plane perpendicular to the plane of rotat-ion ofthe bucket wheel. .A bushing 15I and the bearing 5 are slipped over the shaftv before the bucket-wheel is put on, said bearing having a flange 16 75 which can be secured in the opening in the head 7, preferably by screwinr itin. The opening in the head 9 is/la'rae enough to allow the field magnet'me 17of the enerator to pass through it, and it is close by a ,80

diaphragm'il which carries the bearing 6 at its center, and also'Y supports the brushes 19 of the generator.

The-main bea-ring -1- is mounted in a box' pedestal 2O cast wit the frame, and having 85 lution. Oil rings 24 carry. up oil' from the 90 cellar formed bythe box-pedestal, which can be filled through the oil-hole 25.

The bucket-Wheel 1 is housed in the head 7, which has a flange 26 to which is fastened the cover 27 inclosing the Wheel, and provided with the nozzles 28. The wheel has preferably but one row of'buckets, and vthe exhaust steam escapes through the tube 13 which communicates with the turbine casing by ports 29.

The field ma et frame 17 is circular and carries preferarly two pole pieces. It is attached to the beams 10 and 11 by screws 30 which are received in recesses 31 in said beams. A removable sheet metal cover 32 105 preferably between ribs 33 projecting therefrom. The edges of the cover lie under the beam 11, and are provided with fastening 11 The a1r entering the chamber is deflected by a baille plate 40 to near the end head '9. After flowing vlengthwise of the generator it is caught by a centrifugal fan.41 mounted on 'the shaft in the plane of the annular middle 'head 8. The fan is shut off from the main bearing 4 by a partition 42 so that' it will deliver the heated air to an escape port 43 under the box-pedestal 20. The fan 1s of such a diameter lthat it will pass through the opening in the hed 9. An eye bolt 44 screwed into the upper beam 10 enables the,machine to be readily hoisted.

It will be observed that this design of turbo-generator affords a compact, rigid, selfcontained structure, which by reason of its Athree feet 12 and 14 'will always rest" firmly upon4 any-surface and will not be racked out of shape by ,movements thereof. The combination of transverse heads and longitudinal channel beams gives a.. light but stili frame, while' the removable covers 27' and 32 afford easy access to the moving parts. v

In accordance with the provisions of the' patent statutes, Ivhave described thc principle of operation f my invention together with the apparatus which I now consider to represent the best embodiment thereof; but

I desire to-have it/understood that the apparatus shown is only illustrative,and that the invention can be carried out by other means. Y l

That I claim as new and desire to secure by Letters Patent of the Unit-ed States, is

1. 'A turbo-generator set comprising longitudinally extending channel beams, trans- -verse annular heads formed-.integral with said beams, a shaft, a bucket wheel and rotor mounted thereon, a cover for the wheel that is supported by one of the heads, a bearing fol-'the shaft carried by another head, a stator"l0catedl between and4 carried by the beams, anda second bearing for the shaft carried by one of the beams.

2. A, turbo-generator set Ycomprising lon- 'gitudinally extending channel beams, lo-

cated 'one above the other, parallel annular heads that unite the beams, a single foot for supporting the frame at one end, a pair of feet for supporting the frame at the obner end, a shaft, a bucket wheel carried by the shaft,and located in one' of the heads la. rotor driven by the shaft, and a removal) e stator en aging lthe said,beams and supported there said stator being removable through one of said heads.

3. .A turbo-generator set havin a frame comprising three parallel annu ar `heads united by bine wheel a jacent to the head at one end, a generator between the other' end headand the middle head, and .a Ventilating fan in the plane of said middle head. t

-.4. A turbmgenerator set having'a -frame composed of t ree nnular heads and longitudinal beams, a tu bine -adjacent`to-one of the end heads,` a generatorb'etween the midnltudinal channel beams, a tur- 'nsl dle head and the other end head, a cover inclosing said generator, a hollow foot having air 1nlets, and a `fan in the middle head for .drawing air through said generator.-

5. A turbo-generator set comprising relatively narrow and longitudinally extending channel beams locatedone above the other, heads for uniting the beams, a shaft, a. rotor e-mounted thereon', a stator supported by the.

inner and opposied faces of the beams, a sheet metal cover which iswrapped around the beams and engages them .to and bottom and also engages the heads at lts ends, and. .detachable fastenings for the edges of the cover. l l

6. A turbo-generator havinga frame comprising -annulartra'nsverse heads and longitudinal beams, a generator located between `two of said heads and having a circular field frame adapted to pass, through the opening tached to said head lantl iilling said opening and carrying a beari'g for the generator shaft. l E

7. A turbo-generato prising three annular 'transverse heads and longitudinal beams, a shaft extending centrallyl through said heads, a turbine wheel on said shaft and outside one of saidend heads, a fan on said sh aftvin the plane of the middleV head, a main bearing between said fan and the turbine, a generator armature on said shaft between said fan and the other end head, a circular field frame concentric with said armature', the opening in the adjacent end head bein large enough to admit said fan and field frame, a diaphragm closing said opening, and shaft bearings in saidI diaphragm and 1n the end head adjafV '.eentto the turbine.

8. A turbo-generator set having a. .frame composed of longitudinal beams arranged in the same vertical plane, transverse annular heads for uniting the beams, a removable casing for theframe`that engages the beams and also said heads, feet for su porting the fzame, a conduit in one of said et that supplies air to the interior of the casing, and a. fan for withdrawing air from the casing.

A turbo-generator set having a frame composed of longitudinal beams arranged in the same plane, transverse heads for uniting the beams, a easing that rests on the beams and also on the heads at its edges, a partition, a fan bet-Ween one of the heads and the partition, an air inlet opening into the casing on one side of said head, and a discharge conduit formed inone of said beams on the other side of said head.

l0. A frame forV a turbo-generator set `Comprising; top and bottom beams, annular heads connecting the beams, a tube forming a pa' t of one'head and through which steam is e austed, a stator for the generator that is supported by and between said beams, a cover attached to one head and forming a Chamber, a wheel in the-chamber, a rotor for the generator, a shaft for the wheel and rotor, a bearing for the shaft carried byl the lower beam, and a second bearing for the shaft carried by one of the heads.
