SPECIFICATION forming part Of Letters Patent No. 702,461, dated June 17, 1902.
Application filed December 19, 1
T (LZZ 107mm, it may concern.:
Be it known that I, JOHANNES Nnnnowskl, a subject of the King of Prussia, Emperor of Germany, residing at Dresden, Kingdom of Saxony, Germany,'have invented certainnew and usefulllnprovemenis in Turbine NVhcels,
of which the following is a description.
The turbine wheels hitherto in use are constructed on the water-wheel system, with the modification that in view of the nature of the driving power the wheels were made very sin all ,and 'the blades arranged close together. It is, however, necessary in the case of wheels running at a very high speed, as with the De Laval steam-turbines, to take into consideration the strain put upon the wheel, owing to the centrifugal force, and this involves difficulties in the construction of such wheels which it is the object of thc present invention to remove.
In order to render the present specification easily intelligible, reference is had to the accompanying drawings, in which lsimilar letters of reference denote similar parts throughont the several views.
Figure 1 is a part facial elevation of a wheel constructed according tothe present invention; Fig. 2, a sectional plan of the saine; Fig.
3, a diagram (horizontal section through wall 3o between two channels) showing thearra-ugement of plates forming a modification of the Wheel shown in Figs. l and 2. Figs. 4 and 4 are part-sectional elevationand sectional plan of a further modification, and Figs. 5, 5, and 5 are respectively part 'end and facial elevations and sectional plan of yet another modification.
'lhewheel is formed of.a number of thin metal sheets recessed or perforated around their edges, the said sheets or disks being coaxially mounted and having their recesses or orifices slightly displaced as regards each succeeding sheet or disk, so that the whole set of sheets or disks when iixed together will al; present a ring of recesses or orificesV on or 901. Serial NO- 86,588. TNO model.)
through the whole disk in a direction inclined to the longitudinal axis of the shaft on which the wheel is mounted. l
i Referring to Figs. 1 and 2, the disks a are placed together, as above explained, with their orifices displaced, as at a', and the whole set of disks are clamped together between the cheeks c and fitted in any suitable manner to the shaft I). lVhen the disks, as in Figs. l and 2,1are providedV with a ring of orifices, a
peripheral ring (l may be employed to hold the edges of the disks firmly together. It will be obvious that a wheel of this construction will be very strong,owing to the fact that the centrifugal force will onlyprodnce radial and annular tension in the separatedisks. The disks are advantageously of thin steel plate.
In the modification shown at Fig. 3 the thickness of the individual disks maybe varied-for instance, the inner plates may be of greater thickness. In Figs. 4 and 4a the arrangement is such that only a very fine edge driving medium entering is presented to the having outwardly-turned the outside disks, 7c
lips to guide the steam intothe channels. vIn
Figs. 5, 5,- and 5b the construction of the wheel is similar to that of the Iclton Wheel, allowing of a division of the rays at the central plane of 'the wheel. i
I claim as my invention- A turbine wheel composed o f a series of thin metal plates having a series of channels around their edges, clamping-cheeks to vhold said plates together and means for attaching 8o the whole to a driving-shaft, a peripheral ringto support and close around the edges of all the plates in the manner and for the pur pose substantially as described.
In witness whereof I have hereunto set my hand in presence 'ofstwo Witnesses.
