EL STIC-FLUID TURBINE.

- Specification of Letters .Patent. Patented J an 25 1921 Application filed Au usta, 1919. Serial in. 314,997;

To all whom it and concern siding at Springfield, county of Hampden, State of Massachusetts, and VYAoHEsLAv PErRovsKY, a citizen of the United States, residing at Lynn, county of Essex, State of Massachusetts, have invented certain new and useful Improvements in Elastic-Fluid Turbines, of which the following is a specification. r

The present invention relates toelastic 'fluid' turbines and specifically to the construction of the rotor and the means for at 15 taching buckets or blades thereto and has for its object to improve their construction. Fora consideration of'what we believe to claims appended thereto.

In the drawingwhich' is illustrative of our invention, Figure 1 is a partial axial section of a bladed rotor and Fig. 2 is a partial view in elevation of the same.

3 indicates the main body of a rotor having supporting shaft. The rim of the rotor is somewhat enlarged to furnish the necessary support for the blades 5. The rim is provided with a plurality of concentric shoulders 6, said shoulders having relatively large,

' flat concentric bearing surfaces 7. As shown the faces ofsaid shoulders all terminate in the same vertical plane but this is not es sential' The rim is beveled off at 8 to permit it to enter a recess in the blade bases as willappear later. The rim is also provided with an annular undercut recess 9 and an annular .retaining shoulder" 10. The lower ends of inner end of the blade base is beveled at its inner end and oppositely to the side wall of the recess so that the calking strip when finally forced into place is tapered on-both sides, a feature which aids in holding it in place against centrifugal stresses.

The blades 5 are formed individually as by the drop forging process for example, or they may be cut out of solid stock. However they are made, each blade has a base 12 formed integral therewith which also forms a space block to properly separate the working surfaces of the blades. mach base is providedwith a plurality of concentric shoul- I ders 13 which are thej counterparts ofthe Be it"known that we, GEORGE LVV. PEN-i 'T ENY, a citizenof the United States,re-

shoulders on the rim and when assembled are in firm contact. 'The shoulders on both the ,blades' and rotor 'are'surfaces of revolution provided with a'recess 15 and a shoulder 16. Located in the recess between the shoulder and the rim is a calking strip 17. The

calking strips 11 and 17 are made in sections of suitable length and are forced into place by a suitable calking tool,. Each calking strip may cover an arc equal to one blade or it may cover two or more blades as desired.

The blades with their bases are finished individually and are mounted on the. rim

one after the other, the recesses 9 and 15 permitting this to be done from one side of the rotor, after which they are locked in place by the calking'strips. The blades can be removed by taking out the calking strips, a feature which is desirable for repair pur- :poses.

. ing the blades against centrifugal force. The

overlapping of the shouldered portions of the bases and rim together with the calking strips 11 and 17 located on opposite sides of the rotor and at different radial distances from the rotor axis afford an effective means for resisting strains due to the action of the steam on the blades.

In accordance with the provisions of the patent statutes, we have described the principle of operation of our invention, together with the apparatus which we now consider to represent the best embodiment thereof; but we desire to have it understood that the apparatus shown is only illustrative, and that the invention can be carried out by other means. i

What we claim as new and desire to secure by Letters Patent of the United States, is,-

1. In combination, a turbine member having a plurality of concentrically arranged projections on one only of the side faces of its peripheral portion, the other side face being smooth, blades provided with bases which have similar projections on one side only, said projections interlocking with those on the member and retained thereby, and a'ineans on-op'posite sides of the member for locking the blades in place.

2. In combination, a turbine rotor having a rim with a shoulder on one of the side faces thereof, blades, each of which has a base provided with a shoulder on one of its side faces which engages that'on the rotor,

andmeans on oppositesides of the rotor and at different radial distances from the rotor axis for holding said shoulders in enagement and resisting lateral stresses on the blades when they are subjected to the action of motive fluid.

In combination, a turbine rotor having a rim with a shoulder on the side thereof, blades, each of which has a base provided with a shoulder on one side which engages that on the rotor, and calking strips located on opposite sides of the rotor and at different radial distances from the rotor axis for holding said shoulders in mutual engagement and resisting lateral stresses on the blades when they are subjected to the action of motive fluid.

4;. In combination, a turbine rotor having a rim with a shoulder on its side face and also a circumferential recess to receive the inner ends of the "blade bases, blades, each of which has a shoulder on its base cooperating with that on the rotorandalsoare' cess to receive the periphery of the rotor, and retaining devices located in said recesses for holding the blade against lateral displacement.

5. In combination, a turbine rotor having a tapered .rim portion witha plurality of" concentric shoulders on one of itsside faces, blades, each of which has a tapered base portion with shoulders which cooperate with those onthe rotor, and means located adj acent theends of said tapered portions and at different radial distances from the rotor axis for holding the shoulders in mutual engagement.

In witness whereof, GEORGE NV. PEN- THENY has hereunto set his hand this twenty-eighth day of July, 1919, and VimoHnsLAv PETROVSKY has he'reunto set his hand this thirty-first day of July, 1919.
