. Specification of Letters Patent.

Ia-tentedMay 26, 1914.

Application led August 4, 1913. Serial No. 782,978.

To all 'whom it may concern.'

Be it known that I, CHARLES W. DAKE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Turbines, of which the following is a specification.

My invention relates to improvements in turbines and is illustrated in the accompanying drawing which shows diagrammatically a sectional view with parts broken away and parts omitted of a turbine embodying my invention.

Like parts are indica-ted by the same lettersin the figure.

The turbine housing A completed by a cap or end A1 contains the bearings A2 in which rotate the shaft A3. The hub B on the shaft A3 carries a body B1 upon which are mounted the turbine buckets B2 held in position by lugs B3 and rings B4. A steam nozzle C fed through a stem passage C1 with steam from any suitable source of supply not indicated feeds the steam into the buckets and rotates the turbine.

D is a bearing or guard ring projecting inwardly from the housing A and closely surrounding the outwardly extended edge or rim Dl of the body B1. This/rim D1 in the presentinstance extends out beyond the edge of the buckets although it might not extend so far, in which case the ledge or ring D would necessarily extend farther inward to bring it into the two parts in the same relative position. The purpose of parts D and D1 is obvious. Bearings such as these are designed have high speed and heavy duty. They are frequently improperly cared for and not adequately inspected. It often happens that the bearings wear out. turbine wheel then gets o center and there is a possibility that the buckets will scrape on the steam nozzle thus breaking or bendi ing the buckets, cutting down the efficiency ofthe machine if not actually stopping it- The' and adding greatly to the cost of repair. In

my improved form, when this wear of the bearings take place, the body or bucket Wheel will be still centered within reasonable limits by the collar D supporting the bucket wheel as the periphery D1 thereof comesv in contact therewith, thus Wearing away or breaking up of the buckets is entirely prevented.

It will be evident that my invention is not to be limited to any precise or particular arrangement of parts. It is conceivablethat the supporting ring in the housing might be differently positioned or diiferently sized,

and it is suiiicient that it be of such size as to adequately support the, rotor and that the rotor has a cylindrical surface concentric therewith for the purpose of coming into Contact therewith at the appropriate time, and I wish therefore that my drawing be regai-ded as in a sense diagrammatic.

I claim:

1. In a turbine having a rotor, buckets, I

thereon and a fluid supply nozzle, a housing, the clearance between said housing and said rotor being less than the clearance bet-Ween said nozzle and the buckets` 2. 4A turbine comprising a housing, a ring thereabout, a rotor body, a row of buckets projecting therefrom and a nozzle, the clearance between the nozzle and the buckets being greater than the clearance between the ring and the body.

3. A turbine having a rotor, buckets thereon, a fluid supply nozzle, and a guard in opposition to said rotor, tlic clearance between said guard andthe rotor being less than the clearance between the nozzle and the buckets.

In testimony whereof, I affix my signature in thc presence of two witnesses this 26th day of July, 1913. l
