. To all whom it may concern f ran s'ra Parana orrrbn DANIEL IE. LEPLEY, or CONNELLSVILLE, PENNSYLVANIA.
Be it known. that I, DANIEL F. LEPLEY, a citizen of the United States,residing at Con- "nellsvill'e, in the county of Fayette and State ofPennsylvania, have invented "a new and useful Ventilating Fan-lVheel, of which the followingisaspecification I i The present invention relates "to improvements in ventilating fan wheels, one object of the invention being the provision of a divisional disk of a doublefventilating fan wheel that increases the efliciency "of the fan wheel inthat it prevents'the productions of eddiesdue to high windsandthe like that usually tend to prevent the; maximum passage of'air betweenthe blades when the wind is blowing; from one "side and isl'deflected by the divisional disk.
In constructing fan wheels oft'his character, it is' generally the practice to use a solid divisional'disk of substantially the full diameter of the wheel, thus dividingthe wheel into practically two wheels,"in which the respective'ope'rating sides or blades are isolated from oneanother. It has been found in pr'actisefthat when the wind is blowing from one side and is deflected by the divi' sional disk, that. not only the maximum efliciency of the side. against which the Wind is directed is affected, but the blades upon the opposite side of the disk are also affected, thus preventing the fanfrom operating to produce the desired result. To overcome this defect, it has been found that by reducing the diameter of the divisional disk, so that the periphery thereof is within the inner edge of the outer supporting rings of the fan wheel to produce a concentric space adjacent the intermediate edges of the blades or entirely between the blades at said intermediate portion, that the currents of air due to the wind engaging either side of the divisional disk, will rather assist than retard the proper action of the blades in producing the desired ventilating effect.
Vith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

ing one half of the ventilating fan wheel in side elevation and the other half in section. F ig.'2 is a view illustrating a portion of the fan wheel inend elevation and the lower portion in section.
Referring to the-drawings, the numeral 1 designatcs the sectional shaft engaging members of the fan wheel, which in large wheels is made in two sections so that the wheel transported in two parts for assemblage. The main spokes 4: are carried by the memher 1, while a sectional disk member 3 is disposed uponthe shaft (not shown) intermediate of the members 1, to support the divisional disk or partition 11, to which is attached the radial plates 2. 7
Connected to the outer ends of the plates 2, are the annular members or rims 5 which constitute the main outer rim of the wheel.
Connected tothe spoke at and of lesser width blades are clearly illustrated in Fig. 1, in'
which the longer blades 7 are so constructed that their inner ends are at a tangent to. and
within the periphery of the partitional disk 11 while the inner ends of the blades 8 are at a slightlyless angle than the blades 7 and terminate at a point substantially at the periphery of the disk 11. The blades 9 are between the rims 5 and are substantially the length of the width thereof.
It will be noted that the partitional disk 11 is of a diameter less than the internal diameter of the outer rims 5, therefore providing between its periphery and the inner diameter of the partitional ring 6, the concentric opening 12, thereby providing the passageway for the undue draft or wind blown against either side of the disk 11 so that the same is not deflected to interfere with the efficiency of the blades at the wind side of the disk 11 and at the same time provides a passage so that the currents of air are permitted to pass therebeyond and be properly deflected through the blades at the opposite side of the disk without interfering with the efficiency thereof. It has also been found that the ring or band 6 may be dispensed with, thus providing a clear open space beyond the periphery of the partitional disk 11, it. being essential, however, that the periphery of the disk 11 terminate at a point within the internal diameter of inner diameter of the annular blade supporting members. w
