THADDEUS V. ELLIOTT, OF BROOKLYN, NEW YORK, ASSIGNOR, BY MESNE ASSIGN- MENTS, T WILLIAM F. MARSH AND CLARENCE MQMILLAN, OF NEW YORK, N. Y.

TURBINE.

To all whom it may concern:

Be it known that I, Trmnnnus V. EL- LIOTL, a citizen of the United States, residing in Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Turbines, of which the following is a specification.

The object of this invention is to provide an improved form of rotary fluid pressure motor, that will be simple and cheap in manufacture and highly eflicient in its action.

Another object of the invention is to provide an improved form of rotor in which the blades are attached to the ring by being molded therein by casting.

Another object is to provide an improved construction in which the inlet passes axially at one side, and the outlet for the fluid is on the opposite side in an axial direction.

A further object is to provide improved means for securing the jet members in the rotor.

In the accompanying drawing representing embodiments of my invention, Figure 1 is an end elevation of the device applied to a fan. Fig. 2 is a side elevation partly broken away. Fig. 3 is a section through the motor portion of the device taken on the line 33 indicated in Fig. 1. Fig. 4: is a section on the line H indicated in Fig. 3. Fig. 5 is a section on the line 5-5 of Fig. 3. Fig. 6 is a broken section on the line 66 indicated in Fig. 4. Fig. 7 is a perspective view of one of the blades and Fig. 8 is a longitudinal section through the same. Fig. 9 is a cross section enlarged of one of the blades.

The device is shown applied to a fan in Figs. 13 in which there is a frame member 1 having radial arms 2 on each side that support the shaft member 3. At the center is the motor denoted generally by 4 to the periphery of which the fan blades 10 are secured. But this fan forms no part of the present invention, that relates only to the motor, which can be used to furnish power for any purpose desired. The motor 1 is shown as comprising a stator 5 that is in Specification of Letters Patent.

tegral with the shaft 3, and which is inclosed at its middle portion by the rotor 6. The latter practically has two parts comprising members 7 and 8 that are connected at their periphery by a ring member 9 to which are secured the blades 10. The stator 5 is shown as comprising a ring portion 11 having a hollow shaft portion 12 extending from one side that forms an inlet for the fluid, which inlet connect-s with two radial passages 13 and 14 leading to chambers 15 and 16 at their respective ends. The chamber 15 connects with two jet outlets, shown best in section of Fig. 6. These jets are formed by pipes or nozzles 17 and 18, that are shown as projecting from the opposite side faces of this ring portion 11, making a sharp angle with the plane of rotation and extending in the same circular direction. In the specific construction set forth, just beyond the chamber 15, that has its end walls 19 and 20 inclined, are notches 21 and 22 in the ring member, into which the ct members 17 and 18 extend. These nozzles can be inserted in apertures in these walls 23 and 2 1 if desired, but in the construction shown a plug 25 is passed through the two walls transverse to the faces of the ring, and contains bores through which the jet pipes 17 and 18 extend. This arrangement is for convenience of construction. At the other chamber 16 the jet pipes 27 extend from a plug 28 similar to the construction just described.

The rotor 6 is shown as comprising two ring members 7 and 8 each of which are practically identical. The member 7 has a bearing portion 30 engaging the hollow shaft 12 and may be secured in position by a clamp collar 31. This member has its side face arranged opposite one side face of the stator containing the jet pipes, and such face contains a circular channel 32, in which are arranged the blades to receive the fluid jets. In the form shown, the blades 33 have their extremities secured in the opposite side walls of the channel. The blades are shown in Figs. 7-9 as somewhat cupshaped but elongated, having extensions 34 and 35 at their extremities. These extensions project into suitable sockets in the side walls of this channel portion, and are pref erably secured therein by being cast in the member, the blades or buckets being placed in the mold and the ring member cast thereon. These blades are shown inclined to the jets, as indicated in Fig. 10. This channel 32 in too member 7 of the rotor connects by ports with an inner channel 37 to receive the fluid after leaving the buckets.

The rotor member 6 has its buckets 38 formed and arranged in the same manner to receive the fluid from the et pipes on that side. This member has a bearing member 39 riding on the hollow shaft portion 40 extending from the stator 5. The member 6 has an inner annular channel etl connected by ports e2 with the channel 38 for receiving the fluid after leaving the bucket. The member 6 also has radial ports 44 connecting the channel "e1 with the tubular member 4L0, providing exit for the fluid from the buckets in this member 6. The fluid from the other rotor member 7, passes through open portions 45 and 46 in the stator member across to the channel portion 41 and finds exit from this portion through the hollow shaft 40. By this means it will be seen that the fluid under pressure for the motor enters through the hollow shaft of the stator, passes to the peripheral chamber in the same, thence through ets against the buckets or blades of the rotor sections, and thence through the rotor and through openings in the stator to the hollow shaft of the stator on the opposite side, where it finds exit.
