Specification of Letters Patent.
Patented Aug. '7, 1906.
Application filed December 24,1902. Serial No. 136,455.
To all whom it may concern.-
Be it known that I, AUoUsTE GAMILLE EDMOND RATEAU, a citizen of the Republic of France, residing at Paris, France, have invented a certain new and useful Improvement in Blowing Mechanism, of which the following is a full, clear, concise, and exact description.
-My invention relates to a centrifugal fan or blower; and its object is to produce a device which will be adapted to be driven at very high rates of speed, as by direct connection to a turbine-engine. The rotary element or impeller-wheel of such a fan or blower must necessarily possess great strength because of the enormous centrifugal'strains to which it issubjected.
My invention consists in an impeller-wheel comprising a plate having a series of radial blades projecting beyond its periphery, each blade being preferably provided with a strengthening-rib extending down its back.
The fan of my invention is designed more particularlyfor use in connection with turbine-driven apparatus, and hence in use is subjected to enormous centrifugal force due to the extremely high speed at which such fans are driven. I therefore form the -im peller-wheel in one integral piece, as bein thus less likely to be torn a art by centrifuga force. In practice I have ound the impellerwheel of my invention pecuilarly adapted to withstand the effects of the high speed at which turbine-driven blowers are operated. I will describe my invention more fully by reference to the accompanying drawings, in
Figure 1 is a side elevation, partly in section, of a blower embodying my invention with one section of the housin or casing removed. Fig. 2 is a section on Iine 2 2 of Fig. 1. Fig. 8 is a perspective view of the irnpeller-wheel. 7
Similar numerals of referenceindicate similar arts throughout all the figures.
Each blade 8 is provided with a strengthening-rib 10 on its'back extending to the outer end of the blade, which rib is formed by 1 a radial extension of the central plate.
Having thus described my invention, I claim 1. In a centrifugal tan the combination he bodyportion of the fan, of blades disposed on the face of said plate, and extending radially toward and projecting beyond the periphery thereof, and ribs for'min late and lades to continuations of said extending own the backs of the the outer ends thereof.
2. A rotary fan comprising a hub, a circular plate integral therewith, and-a series of outwardly-tapering blades integral with said plate and projecting radially beyond the pe riphery or said plate; each blade having a portion extending laterally from each face of the plate, and a stren thening-rib forming a continuation of the p ate.
3. An impeller-wheel formed of an integral piece and comprising a circular plate, a series of outwardlytapering blades, each blade projecting on eac side of the plate and extending radially from near the axis of said wheeltoward and beyond the eriphery of said plate, and strengthening-ride extending from said plate down the backs of the blades.
In testimony whereof I have signed this specification in the presence of two subscrib ing witnesses.
AUGUSTE QAMILIIE EDMOND RATEAU.
