Specification of Letters Patent.
Patented. June 11, 1907.
, Application filed April 1,1904. Renewed April 22, 1907. Serial No. 369,575.
TooZZ whom it may concern;
Be it known that I, CHARLES A. BAoK- STROM, a citizen of the United States, residing at Milwaukee, county of Milwaukee, and
'State of Visconsin, have inventednew and useful Improvements in Turbine Nozzle- Partitions and Running-Wheels, of which the following is a specification.
My invention relates to improvements in turbine nozzle partitions and running wheels.
The objects of my invention are to provide means whereby the formation of the nozzle passages is facilitated and to improve the construction of the nozzle partition and running wheels in certain details hereinafter described and claimed.
In the following description reference is had to the accompanying drawings in which; 1
Figure 1 is a segment of a nozzle ring showing the same in section on a radial plane cutting the nozzles and with some of the nozzle members removed to show the channels in which their edges are engaged. Fig. 2 is a detail sectional view, showing a portion of the nozzle partition in its relation to the running wheel. Fig. 3 is a detail view of a portion of the inner face of a nozzle ring.
Like parts are identified by the same reference characters throughout the several views.
Referring to Fig. 2, which best shows the relation of the parts, 1 is the outer casing, 2 a nozzle ring, and 3 a running wheel. The nozzle ring 2 forms one member of a partition subdividing the turbine transversely and composed of said nozzle ring and the partition members 5 and 6 extending outwardly and inwardly from its respective edges. The member 5 is, in the construction .shown, formed integrally with the outer oasing 1, and the member 6 integrally with the nozzle ring, which is keyed to the member 5 at 8. The member 6 is preferably formed with a conical rearward pitch from the hub 9 of the running wheel to the nozzle ring, the object of this being to afford greater resistence for a given weight of material than can be secured by a fiat disk.
The running wheel is formed with side disks aa and vanes b interposed between them and arranged to receive the motive fluid delivered inwardly by the nozzles as indicated by arrows in Fig. 2. The edges of the disks aa are beveled inwardly as indicated at d to compensate for inaccuracies in construction and relative position of the nozzle ring and the running wheel.
Referring more particularly to the nozzle ring, it will be observed, (Figs. 1 and 3) that the ring is provided with segmental slots 12 which are subdivided into nozzles by partition plates 13 which are formed to fit V shaped channels 14 in the side walls of the slots. With this construction, the slots can be first milled out to the exact size and shape required and the plates 13 subsequently pressed forcibly into the channels to subdivide them into separate nozzle apertures. The plates may therefore be stamped out from sheet metal. They are pressed into position with sufficient force to insure their retention.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is,
1. In a turbine, the combination of a nozzle ring provided with a slot, and a plate subdividing said slot and provided with con verging edge surfaces fitting corresponding channels in the side walls of the slot.
2. In a turbine a nozzle partition, having one member projecting inwardly from the outer casing, a cylindrical nozzle ring keyed to said member, and an inner member con nected with the nozzle ring and having a bearing on the hub of the running wheel.
3. In a turbine, a nozzle partition, having one member projecting inwardly from the outer casing, a cylindrical nozzle ring keyed to said member, and an inner member connected with the nozzle ring and having a bearing on the hub of the running wheel; said inner member having a conical rearward slope from the hub to the nozzle ring.
4. In a turbine, the combination of a running wheel having side disks and vanes secured between the disks; said disks having their outer edges beveled inwardly in the direction of the vanes; and a nozzle ring encircling said running wheel and provided with nozzles arranged for an inward delivery of motive fluid to the vanes.
In testimony whereof I afiix my signature in the presence of two witnesses.
CHARLES A. BACKSTROM. Witnesses:
JAs. B. ERWIN, LEVERETT 0. WHEELER.
