GUSTAF M. ANDERSSON, OF HYDEPARK, MASSACHUSETTS, ASSIGNOR TO VERMONT FARM MACHINE COMPANY, OF BELLOl/VS FALLS, VERMONT, A JOINT STOCK CORPORATION OF VERMONT.
TURBINE.
SPECIFICATION forming part of Letters Patent No. 765,761, dated July 26, 1904.
Application filed August 15, 1903.
To all whom it may concern:
Be it known that I, GUs'rAE M. ANDERssoN, a citizen of the United States of America, and a resident of Hydepark, county of Norfolk, and State of Massachusetts, have invented certain new and useful Improvements in Turbine- Engines, of which the following is a specification.
My invention relates to turbine-engines in which two or more bucket-wheels are combined in such a way that the steam acts on them successively for repeated impulses by reaction of the escaping steam from one upon another for economizing the expansive force of the steam, said wheels being geared together for combined effect upon one powershaft; and the invention consists, essentially, in a novel organization of a plurality of wheels and in the form of the jet-nozzle by which the steam is applied and the form of the buckets for conserving concentrated and therefore more effective action of the steam, as hereinafter described, reference being made to the accompanying drawings, in which Figure 1 is a plan View of myimproved turbine-engine with some parts broken out, showing some of the buckets in longitudinal section. Fig. 2 is a vertical section of the same on line 2 2 of Fig. 1. Fig. 3 is a detail of the bucket-face of a wheel laid out flat and show: ing the V shape of the buckets longitudinally. Fig. 4: is a transverse section of the steam-jet nozzle. Fig. 5 is a plan View in part of a modified form of my improved engine. Fig. 6 is a vertical section of Fig. 5 on line 5 5. Fig. '7 is a detail in section on line 6 6 of Fig. 6. Fig. 8 is a plan view of another modification. Fig. 9 is a vertical section of the wheel partly represented in Fig. 8.
Referring to Figs. 1 and 2, a and 5 represent a couple of horizontal bucket- \vheels arranged on vertical shafts 0 to run face to face, both in the same direction, so that the contiguous faces run reversely to each other. The shafts c are geared by pinions (Z with the wheel 0 on a power-shaft f. g represents the buckets of the said wheels (0 Z), and it represents the Serial No. 169,620. (No model.)
jet-nozzle for applying the steam to the buck-- ets of wheel a, said nozzle being located within the bucket-rim and the buckets of saidwheel being arranged to receive the steam from within said rim and discharge it at the periphery. The buckets of wheel 5 are arranged to receive the steam at the periphery of the wheel and discharge it within the rim.
Steam is supplied to the nozzle it through one side of the case at i, and the exhaust-steam escapes at 7'. The buckets are V-shaped in cross-section, but have about the usual curve lengthwise for giving reverse direction to the steam escaping from them, and the jet-nozzle is of triangular cross-section, corresponding with the V-shaped buckets and disposed in angular relation thereto, whereby the angular buckets and this angularity tend to more effective concentration of the steam than where the form of the nozzle and the buckets favor spreading of the jet.
In Figs/5 and 6 the buckets g and the nozzle it have the same angular form and relative arrangement; but the disposition of the buckets is in such relation to the wheel as to receive the steam sidewise of the wheel-rim c and issue at the opposite side, where another wheel .7) receives the steam and discharges it in like manner, these wheels being on parallel shafts c and overlapping each other sidewise to the extent of the side faces of bucket-rims. They are likewise geared to a power-shaft f by pinions a and an intermediate Wheelc. A third wheel b isrepresented on the same shaft as wheel a as taking steam from wheel 6, and, if desired, the series of wheels may be continued indefinitely in the order shown.
In Figs. 8 and 9 the same transverse V- formed and lengthwise-curved buckets g and triangular nozzle 7&2 are represented with a large horizontal wheel a receiving the steam at two points in its upper side face and discharging it from the otherside face into the side faces, respectively, of two smaller wheels 6*, said wheels If being geared by pinions (Z with the wheel 6 on the power-shaft f Other modified constructions of wheels and. organizations of pluralities of wheels may of course be employed.
In using the word face in the claims I refer either to the peripheral face or to the side faces of the bucket-Wheel.
\V hat I claim as my invention .is-
1. In a turbine a plurality of individual bucket-wheels mounted on a plurality of axes which are geared together, said wheels being in the same plane and in operative relation to one another; the buckets on one wheel being arranged to receive fluid from within its rim and discharge at its periphery; the buckets of the other wheel being arranged to receive the fluid at its periphery and discharge it within the rim; the buckets of said coacting wheels being so arranged that the discharge from the first-mentioned wheel will be operative on the buckets of the last-mentioned wheel, substantially as described and for the purposes set forth.
2. The improvement in steam-turbines consisting of the combination of a bucket-wheel having longitudinally \I-shaped and circumferentially-curved buckets, and a triangular steam-jet nozzle, said buckets and nozzle coinciding with respect of their angularities.
3. The combination in a steam-turbine, of a pair of bucket-wheels running face to face on different axes for discharging from the face of the bucket-rim of one of said wheels into the face of the rim of the other bucket-wheel, said bucket-wheels being provided with longitudinally shaped and circumferentially curved buckets, and a steam-nozzle supplying steam to the inner face of the bucket-rim of one of said wheels.
4:. The improvement in steam-turbines consisting of the combination with a bucket-wheel having suitably-shaped buckets, of a triangular-shaped nozzle.
5. The combination in a steam-turbine of a pair of bucket-wheels running face to face for discharging from the face of the bucket-rim of one of said bucket-Wheels into the face of the rim of the other bucket-wheel, and a triangu'larly shaped steam nozzle supplying steam to the bucket-rim of one of said wheels.
Signed at Hydepark, Massachusetts, this 9th day of June, 1903.
