T o all, whom it may concern:

Be it known that I, ALEXANDER H. Flam', a citizen of the Unitedl States of America., residing at Cananea, Mexico, have'invented new and useful Improvements in Steam- Turbines, of which the following is a specific-ation.

This invention relates to steam turbines, the object in view being to provide an exceedingly simple and effective motor o f the class described, embodying a novel construction and form of rotor which will greatly facilitate the manufacture of the rotor, and

any subsequent repair that may be needed thereto.

With the above and other objects in view,

the invention consists in the construction, combination and arrangement of parts, as will be hereinafter more fully described, illustrated in the accompanying drawings, and pointed out in the' claims hereunto appeded.

In the drawings: Figure 1 is a front elevation of a'steam turbine, embodying theA present invention. Fig. 2 is a vertical cross section'through the same. Fig. --3 is a view in elevationV of the rotor, showing the arrangement of steam tubes and ports. Fig. 4 is an end view of the rotor.

The main feature of the present invention resides in the f o'rm and construction of the rotor, which, as illustrated in the drawings, comprises a. substantially cylindrical body 1 provided about centrally thereof or at any suitable point intermediate its ends with an annular Hange 2, extending circumferentially around the body, and of a suitable depth to accommodate one or more layers of steam tubes, as shown in Fig. 4. The flange 2 is provided with steam inlet ports 3 arranged in a circular series, extending entirely around the periphery of the ange 2, and communicating with the ports 3, as shown in Fig. 3, are two laterally arranged series of steam tubes 4 which lead from the ports 3 outwardly toward the opposite ends of the' rotor, and are disposed substantially in a spiral relation to the rotor, said tubes terminating at or near the extreme ends of the rotor, as indicated in said Fig. 3.

Encircling the ange 2 is a steam ring 5 which is provided with a steam inlet port 6,'

with Which ll of the ports 3 register, during the revo ution of the rotor. This steam ring serves to close all of the remaining ports 3, and thereby admit steam toonlyj and serve to .ing with said ports one of the ports at a time, the steam passing thence through the tubesv4 and-.escaping from the opposite ends thereof, but inthe meantime traversing a substantially spiral course, which serves to give the requisite pull on the rotor- I A'casing 7 of suitable construction surrounds and incloses the rotor, and carries a plurality of binding screws 8, the inner ends of which impinge against the steam ring hold 'the latter stationary and 1n proper relation'to the flange 2 of' the rotor, thereby preventing the steam fromv escaping. The rotor isqnounted fast upon a central shaft 9 which has bearings in the end Walls or heads 10 and 11 of the casing. Said shaft may be mounted in bearing standards 12 connected to a suitablebasel which also supports the casing of the turbine.

As the steam under pressure escapes from thc spirally arranged tubes, it impinges against the heads or end walls of the casing, and a rapid revolution is thereby imparted to the rotor. Y The power generated by the 'turbine may be belted orot-herwise transmitted off from the shaft 9.

What is claimed is: i

1. In a steam turbine, a rotor comprising a cylindrical body, an annular Harige extending circumferentially around the body inl termediate the ends thereof and provided with steam inlet ports in its peripheralface,

and steam tubes communicating with said ports and extending therefrom around the end portions of the body ina substantially spiral direction.

2. In a steam turbine, a rotorcomprising a cylindrical body, an annular fiange extend ing circumferentially around the body and provided with steam iniet ports in its peripheral face, and tim tubes communicatnid extending therefrom around the body 'in a substantially spiral direction.

3. In a steam turbine, a rotor comprising a cylindrical body, an annular fiange extending circumfe ent-iaily around the body intermediate the nds thereof and provided with.'

steam inlet ports in its peripheral face, al

steam ring encircling said .tiange and provided with an inlet port, and steam tubes communicating with said ports and extending il ..cni around we portions of the bodyv in a substantiaily spiral direction'.

4. In a steam turbine, a rotor comprising a cylindrical' body, an annuiar ange extending circumferentiully 'around the body intermediate the ends thereof and provided with steam inlet ports in its peripheral facera Stefan ring encircling Said iange and pro-l vided with an inlet port, steam tubes coin inunicating with said ports and .extending 'therefrom around the end portions of the body in a substantially spiral dineetion, and a easing inelosing therotor sind'y provided with steam inlet and exhaust ports. d

5. In steam turbine? a, rotor comprising va` cylindrical body, :in annular ange extending cireuniferentially around the body and.

provided with steamvinlet ports ini its peripheral face, steam tubes communicating with seid ports and extending therefromV around the body in arsubstantially spiral direction, and a Stationary steam ring encircling said Harige and 'provided with an inlet port. y l
