It-kIIOWll hart, Joxarnax S- Gnn'zx, a -CItIZenof'=-the-United States, and a resident fluid turbines of the impaetand re- I pond the blades and vanes, o i. means to this end have been pro- .1 posed. shrouded, it has been"- found necessary to pr0- ride some sort o ftt guard or abutment for reducing the leakage of steam bet *een the shrouds and the casing or rotor, as the case may be. Various means to this end have been attempted, but all of them'with which I am familiar are more or less costly, and an objectof this invention has been to produce a simple means'to this end. This object I attain by means of the device described in the specification and illustrated in the drawings ac'commnving this application, and throughout the several views of which similar elements are denoted by like characters.
In the drawings, Ifigure l is a View in end elevation of a plurality of turbine blades or vanes arranged in annular rows, in which the holding elements, that is, the stator and the rotor, are equipped with this device: Fig. 2 is a plan view taken on the line A-A in Fig. 1 looking in the direction of the ar rows: Fig; 3 is a view in perspective of a portion of a stator or rot r, as the case n'iay be, to which three blades or vanes are secured, and which stator or rotor is equipped with this invention.
The blade or V3116 holding element is provided with circumferentially extending or annular slots or channels. Into these slots or channels a steel or other suitable metal strip t is'placcd, which extends out beyond the surface of the homing member a suiticientdistance to form the desired abutment or guard, as shown in Fig. 1.

. It is apparent fromt-thgfoigego tion that'my inventionq n bf connection with rotor blades or stator vanes and for that reason I do not wish to limit myself to any specific use. In the following claims, I will use the words blade or blades in their broadest sense; that is, to include both the rotating blades and the stationary vanes of a turbine.
Having thus described this invent-ion, what I claim is:
1. In combination with a blade holding element provided with a circumferentially extending or annular slot or channel, a guard or abutment piece the base-of which lies within said slot or channel, a plurality of blades lying withinsaid slot-and separate calking or spacing pieces alternating with said blades.
2. In an elastic fluid turbine, in combination with the annular rows of shrouded rotor blades, the roots of which are secured within slots or channels by means of separate alhing and spacing pieces, abutment pieces secured in said slots or channels and which project therefrom.
3. In combination with a blade holding element provided with a circumferentiallyextending slot, anabutment piece, the base of which lies within said slot, a plurality of 100 blades adjacent thereto and means for iounting said blades within said slot.
In combination withan annular row of turbine blades, 21 guardor abutmentpiece mounted on the discharge or exhaust side 105 thereof.
5. In combination with an annular row of turbine blades, means for mounting said I blades, and a guard I, or abutment piece I mounted adjacent to the bases of said blades.
.6. In combination with a blade holding element provided with a circumferentiallyextending slot, a plurality of blades mounted in said slot, and-a guard or abutment piece mounted in said slot. 7. In combination with a blade holding element, provided with a circumferentiallyextending slot, a uard or abutment piece, the base of which ies within said slot, and separate calkin'g means forv each-blade.
8. In Combination with an elastic fluid turbine, a rotor element, a circumferentially- I extending slot therein, a plurality of. shrouded blades, means for mounting saidblades- 1n saids1ots,'and an abutment piece secured in said slot which projects therefrom.
' 9. In combination with an'elastic fluid turbine, a rotor element, a circumferentially= extending slot therein, a plurality of blades, 20
means for mounting said blades in said slots,
and an abutment piece secured in said slot which projectstherefrom.

ing element of a turbine, a blade mountin slot provided in said element, a plurality o blades and a segmental abutment piece secured in said slot and projecting therefrom.
12. In combination with the blade hold- -ing element of an elastic fluid turbingiiz circumferentially extending slot, an a'butment piece'ldcated within said slot and projecting therefrom, a plurality of blades located within said slot. and separate spacing pieces 14. In combination? with an annular row of stationary blades, an abutment, piece mounted on the discharge side thereof.
