UNITED STATES 1.637.652 PATENT OFFICE.

IAN 01mm panama nea :ne as, ma. semi zo. ,o.

This invention relates to improvements in multi-blade or multi-vane fans or blowers.

The eneral construction of this type of fan or lower consists of two end members between which are arranged blades or vanes which are longitudinally straight and arcuate in cross section. Heretofore it has been customary to fasten the ends of the blades or vanes to the end members either by-spot welding or by rivetingfandewhen rivets are used, there are usuall vtwo or more rivets which fasten each en of each blade to its respective end member. In riveting or welding considerable time and labor is required for fastening the blades to the end. members.

The primary object of this invention is to provide an improved means for fastening the ends of the blades to the end members whereby the assembly of the fan can be cheapened and the time r uired can be reduced. The invention consists essentially of forming lugs on the ends of the ends of the blades or vanes, which lugs extend through apertures in the end members and are clinched or bent against the exterior surfaces thereof, as distinguished from rivets and welding heretofore employed.

With the foregoing and other objects in view which will be made manifest in the following detailed description and specifically pointed out in the appended claims, reference is had to the accompanying drawings for an illustrative embodiment of the invention, wherein:

Figure 1 is a vertical section taken ,though the improved fan or blower,

Fig. 2 is a vertical section taken substantially on the line 2-2 of Fig. 1,

Fig. 3 is a perspective view illustrating the end of a blade about to be assembled with an end member,

Fig. 4 is a perspective viewillustrating hedblade and end member as being assem Fig. 5 is a perspective view illustrating the appearance of the blade and end member after the blade has been secured to the end member,

Fig. 6 is a view illustrating a modified form of construction, and

Fig. 7 is a sectional view illustrating a further modified form of construction.

Referring to the accompanying drawings wherein similar reference characters designate similar parts throughout, the general construction of the fan or blower consists of a cylindrical housing 10 havin an axial inlet 1 1 at one of its ends and aving a tangentlal outlet 12. Within the housing there 1s disposed a fan adapted to be driven in any suitable manner as by a motor 13. The rotor shaft of the motor 13 is illustrated as being extended, and a hub 14 is fastened thereto as by a set screw 15. The hub 14 has an annular flange 16 to which is fastened an annular plate 17 as by screws 18. The hub 14 with the annular plate 17 constitutes one of the end members of the fan. The other end member is in the form of an annular ring 19. Between the annular plate 17 and the ring 19 are disposed the blades or vanes 20. These blades are longitudinally straight and are arcuate in cross section, having their inner sides substantiall gent to radii from the center of the The invention consists in providing an improved means for fastening the blades 20th the annular plate 17 and the spacing ring 19,

which constitute the end members. In the annular plate 17 and in the ring 19 there are formed arcuate slots or apertures 21, and on the ends of the blades 20 there are formed lugs 22 which are of smaller width than the width of the blades, providing shoulders 2.3;385

The lugs 22 are continuations of the ends. the blades and are also arcuate in cross tion. In assemblin the fan, the lugs 22 are extended through t e arcuate slots or apertures 21 so that the shoulders 23 bear against the interior surfaces of the end members. Those portions of the arcuate lugs 22, which extend through the end members are bent against the exterior surfaces thereof, as clearly indicated in Fi 5. In this manner the arcuate lugs 22 are nt against a curved edge provided by the arcuate slots or apertures 21. In so bending the lugs, the metal of the blades is so stressed or strained as to gidly fasten the blades 20 to the end mem- A further eculiar feature about this particular assem ly resides in the fact that it is very diicult to rebend the projecting ends of the lugs 22 without breaking so that there' is very little danger of the blades loosening between the end members during the rotation of the fan. When small sized fans are constructed, it is only necessary that one lug be formed on each end of each blade. When larger sized fans are emplo ed, it is sometimes desirable to form a p urality of lugs;

lugs, which shoulders abl formed ofv'sheet metal and is bendable to ga cilitate the entering of the lugs 22 into their respective apertures. In some types offans, because of the fact that the ring 19 is bendable,the fan does not assume as rigid a structure as desired when completely assembled. It is therefore advantageous to stilen the spacing ring 19. This may be done by app ying a second ring 24 which is a counterpart of the ring 19 and is applied to the exterior surface thereof. Preferably Athe ring 24 has depressions formed therein,

as indicated at 25, which receive the bentover portions of the lugs 22 or 22 as the case may be. In this manner the bodies of the rings 19 and 24 are contiguous so that nol spaces will be between them which might produce whistling as the fan is being driven.

From the above it will be appreciated that an improved fan is provided which can be easily, quickly and cheaply constructed, as

compared with the methods of assembly without departing from the splrlt or scope' of the invention as defined by claims.

I claim:

1. A fan or blower comprising an end member, a second end member in the form of an annular ring, blades or vanes disposed between the end members, said vblades or vanes having lugs at their ends extending through slots in said end members, and a secon ary ring positioned against the exterior surface of the second end member as and for the purpose described.

2. A fan or blower comprising an end member, a second end member in the form of an annular ring, blades or vanes disposed between the end members, said blades or vanes having lugs at their ends extending through slots in said end members, and a secondary ring positioned against the exterior surface of the second end member, said secondary ring having depressions formed therein adapted to receive the lugs upon said blades 0r vanes.

Intestimony whereof I have signed my the appended 'name to this specification.

W. H. C. NESS.
