UNITED STATES PATENT OFFICE.

ROBERT HENDERSON, OF THOMASTON, CONNECTICUT.

TURBINE.

To all whom it may concern:

Be it known that I, ROBERT HENDERSON, a citizen of the United States, residing at Thomaston, in the county of Litchfield and State of Connecticut, have invented a new and useful Im rovement in Turbines; and I do hereby declare the following, when taken in connection with the accompanying drawings, and the numerals of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure 1. a side View partially in section of a turbine constructed in accordance with my invention. Fig. 2 a vertical sectional view of the same. Fig. 3 shows two buckets one in side view and the other in section. Fig. 4 a top or plan view of two buckets, one being shown in broken lines.

This invention relates to an improvement in turbines, and while particularly intended for use with steam, is equally applicable for. water, the object of the invention being a simple and effective arrangement of parts and the invention consists in the construction hereinafter described and particularly recited in the claims.

In carrying out my invention, the casing consists of a central ring 2 and side shells 3 and 4. These shells are bolted to the casing which is provided with feet 5 and. 6 by which it may be supported. This central ring and the shells form a steam chamber, and the sides 3, 4, are formed with hubs 7 and 8 for a shaft 9. The ring 2 is formed at the top with an inlet opening 10 and at the bottom with an outlet 11 which intersects a transverse passage 12 which registers at opposite ends with ports 13 and 14 formed in the respective sides 3 and. 4. Within the central ring and secured to one of the shells is a nozzle ring 15. This ring has a series of nozzles 16 more or less in number and arranged tangentially to the shaft. Mounted upon, and keyed to the shaft is a bucket wheel 17 carrying on its periphery a series of buckets 18. Preferably the number of buckets will be half as many again as the number of nozzles.

Specification of Letters Patent.

Application filed May 17, 1909.

Patented Aug. 24, 1909.

SeriaLNo. 496,519.

These buckets which form an important part of my invention, are cast metal buckets and provided with flanges 19 which are embedded in the periphery of the wheel 17. Each bucket is formed with a transversely rounded projecting nose 20 and each nose enters the next succeedin bucket. Or in other words, the buckets are formed by the spaces between the several members. This particular form of bucket prevents Windage. Steam or water being admitted at the top through the opening 10 will fill the chamber, and passing through the nozzles 16 will enter the several buckets and force the wheel 17 to revolve. Having performed its function, the exhaust steam or water will escape through the ports 18 and 14 and out of the exhaust outlet 11.

It will thus be seen that I have provided an extremely simple arrangement of turbine which is particularly effective in operation.

I claim 1. A turbine comprising a casing, a nozzle ring mounted therein, and a bucket wheel. adapted to revolve and provided on its periphery with a series of closely arranged buckets each bucket formed with beveled edges adapted to be engaged with the rim of the bucket wheel and each bucket having a forwardly projecting tapered nose.

2. A turbine comprising a casing formed from a central ring with shells secured to opposite sides, a centrally arranged nozzle ring located between said sides and formed with a series of tangentially arranged nozzles, an inlet opening in the top of the central ring, outlets at the bottom of the sides, said outlets connecting with the outlet opening at the bottom of the central ring, and a bucket wheel arranged within the nozzle ring and carrying a series of closely arranged buckets.

In testimony whereof, I have signed this specification in the presence of two subscribmg witnesses.

ROBERT HENDERSON.
