ating in a highly-efiicient manner at relatively low speeds.
A further object of my invention is to provide asimple form of compound turbine which can be conveniently governed to produce a highly-eflicient operation under great ranges of load.
A further object of my invention is to provide a simple and compact form of turbine capable of developing large power and which can be conveniently assembled and stripped.
In the accompanying drawings, forming a part of this application, and in which similar reference -symbols indicate corresponding parts in the several views, Figure 1 is a vertical axial sectional view illustrating a preferred embodiment of my invention. Fig. 2 is a sectional view, on a reduced scale, taken on the line 2 2 of Fig. 1. Fig. 3 isa sectional View, on a reduced scale, on the line 3 3 of Fig. 1; and Fig. 4 is a view similar to Fig. l with the rotor and port-rings removed, the interior of the casing being shown in elevation.
Referring to the drawings, 1 indicates a turbine-shaft suitably journaled in the heads 2 of the turbine-casing and carryingtwo sets of disks 3, 4, 5, 6, and 7. An initial series of vanes 8 is secured between the adjacent end disks 3 3 of said two sets and intermediate of two lateral sets of annular series of vanes 9, 10, 11, and 12, secured between the several disks 4, 5, 6, and 7, said respective series of vanes circumscribing annular chambers 13, 14, 15, 16, and 17, formed in the corresponding disks. Two similar sets of arc- shaped members 18, 19, 20, 21, and 22 are secured within the shell 23 of the turbine-casing and to receive steam from the chest 25 and direct it at an efficient angle about a portion of the periphery of the annular series of vanes 8.
The two arc-shaped members 18 are provided with deflecting-passages 28, constructed to receive steam from a set of discharge-ports 29, formed in the port-ring 26. said deflecting-passages and set of discharge-ports preferably extending about the periphery of the annular series of vanes 8 through a greater number of degrees than that subtended by the set of admission-ports. (See Fig. 2.) An adjustable governing or cut-off ring 48 is rotatably mounted on the port-ring 26 and provided with a plurality of apertures 49 and 50, arranged to register, respectively, with the admission-ports 27 and discharge-ports 29 in said ring. Any suitable automatically-controlled or manually-operated means may be employed for shifting the governing-rings. l have illustrated for this purpose a worm 51, meshing with worm-teeth 52 on the gov erning-ring and provided With an actuating hand-wheel 53, external to the turbine-casing. This construction enables the steam admission and discharge of the vanes 9 to be regulated by a single adjustable means and provides a very efl icient means for conveniently governing the turbine.
Each deflecting-passage 28 is constructed to laterally deflect the steam received from the discharge-ports 29 and is provided with a widened portion 30 for conducting such steam to the entrance-orifices of a set of admissionports 31, formed in a curved port member 32 and constructed to direct the steam at an eflicient angle inwardly through a portion of the periphery of the corresponding annular series of vanes 9. The steam is discharged outwardly through a portion of the periphcry of the annular series of vanes 9 into a deflecting-passage 3 1, formed in the arc-shaped member 21, said deflecting-passage being provided with a widened portion 35 for directing such discharge to a set of admission-ports 36 in a curved port member 37 and constructed to direct the steam at an efficient angle inwardly through a portion of the periphery of the corresponding annular series of vanes 10. The steam is discharged outwardly through a portion of the periphery of the annular series of vanes 10 into a deflecting-passage 39,formed in the arc-shaped member 19, said deflectingpassage being provided with a widened portion 10 for directing such discharge to a set of admission-ports 4:1 in a curved port member 42 and constructed to direct the steam at an efficient angle inwardly through a portion of the periphery of the corresponding annular series of vanes 11. The steam is discharged outwardly through a portion of the periphery of the annular series of vanes 11 into a deflecting-passage 44, formed in the arc-shaped member 22, said deflecting-passage being provided with a widened portion 45 for directing such discharge to a set of admission-ports 46, formed in a curved port member 47, surrounding the lower portion of the periphery of the corresponding annular series of vanes 12. Each arc-shaped member is provided with a deflecting-passage 54, constructed to receive the exhaust from the vanes 12 and to deflect the same laterally into the interior of the turbine-casing, from which it can be discharged through suitable conduits 55 to the atmosphere or into a condenser.
It will be noted that the discharge from each annular series of vanes occurs through a portion of its periphery larger than that subtended by the admission-ports and that the vanes of the successive annular series are formed of progressively increased width. This construction provides very satisfactorily for the expansion of the actuating-steam in passing through the successive series of vanes; but other arrangements could be employed for this purpose, if desired. Anydesired number of the annular series of vanes 9, 10, 11, and 12 can, obviously, be provided with dischargeports bya-construction similar to that illustrated in reference to the annular series of vanes 8. In theconstruction illustrated the steam is directed upward through the five annular series of vanes 8, 10, 10, 12, and 12 and downward through the four annular series of vanes 9, 9, 11, and 11, thereby producing an unbalanced system in which there is an excess of upward pressure, tending to balance the weight of the rotor. It will be obvious that the deflecting-passages could be arranged to direct the steam upwardly through all or any desired number of the annular series of vanes for the purpose of increasing the eflective upward pressure for balancing the rotor.
In the operation of my invention steam or other actuating medium is maintained at any desired pressure Within the arc-shaped chest 25, from which it is directed by the admissionports 27 against the vanes 8 and into the annular chamber 13 circumscribed thereby. The steam thus directed into the annular chamber passes through that portion of the annular series of vanes 9 which is subtended by the set of discharge ports 29 and is discharged through the latter. As shown especially in Fig. 2, the aggregate area of the dischargeports exceeds that of the admission-ports, and hence the pressure of the steam will be regenerated adjacent the inner edges of the vanes which are subtended by the set of exhaustports and which thereby act to materially reduce the cross-section of the steam-current flowing to said exhaust-ports. The steam discharged through the ports 29 into the deflecting-passages 28 is deflected laterally thereby in both directions and conducted by the widened portions 30 of said passages to the entrance-orifices of the set of admission-ports 31. The steam is directed by the admissionports 31 against the vanes 9 and into the annular chamber 14 circumscribed thereby. The steam thus directed into the annular chamber 1 1 passes through that portion of the annular series of vanes which is subtended by the deflecting-passage 34:. The steam is deflected by the passage 34: and conducted by the widened portion 35 thereof to the entranceorifices of .the set of admission-ports 36, which direct it against the vanes 10 and into the annular chamber 15 circumscribed thereby. The steam passes from the annular chamber through that portion of theannular series of vanes which is subtended by the deflectingchamber 39. The deflecting-passage 39 conducts the steam to the set of admission-ports 41, by which it is directed through the annular series of vanes 11 and into the deflectingpassages 44:, which conduct it to the final series of vanes 12, all in a manner similar to that just described.
