ATTACHMENT FOR FANS.

Specification of Letters Patent.

Patented Dec. a, ram.

Ap ilicationfiled November 25, 1916. Serial No. 133,431.,

' Fans, of which the following is a specification. This invention relates ,.to improvements in attachments for fans, and has particular application to a device, for deflecting the gir in desired directions from an electric In carrying out the present invention, it is my purpose to provide an attachment of the class described, which will embody a set of deflecting blades arranged in advance of the fan. and connected to the cage of the latter, and capable of'relative adjustment to difl'erentangular positions, so that the air from the fan may be deflected, and means associated with the blades for holding the latter in adjusted position, thereby preventing accidental relative movement of the parts, .and these so arranged and correlatedblades after the latter have been set.

It is also my purpose to provide an attachment of the class described, which may.

be quickly and conveniently attached to the cage of the fan, which may be manufactured! and sold at a comparatively small cost, and

which will embody comparatively few as to reduce the possibility of derangement to a minimum.

With the above and other objects in view, the invention". consists in the construction, combination and arrangement of parts hereinafter set forth and falling within the scope of the claims.

In the accompanying drawings I Figure 1 is a view lnfront elevation of my attachment applied to an electric fan.

Fig. 2 is a top plan'view of the attachment removed from the fan.

Fig. 3 is a view in elevation of a detail of the attachment.

Fig. 4 is an enlarged side elevation of one of theblades.

Fig. 5 is a plan view of the plate, for holding the deflector blades and associatedparts.

Referring now to the drawings in detail, 1 designates an electric fan including fan blades 2 mounted upon the armature shaft of the motor to rotate withsaid shaft, and a circular cage 3 inclosing the fan blades. In

the present instance, my attachment includes a support composed of a single length ofv Wire 4 bent upon itself between its ends to wardly, as at 9, and the upper ends of the portions 9 are formed to provide hooks 10 that engage the ring ofthe cage to hold the wire against the outer face of the cage.

11 designates a plate having a straight edge 12 and an irregular edge 13, and the irregular edge 13 is formed with notches 14 suitably spaced apart along such edge. This plate 11 is arranged horlzontally and thestraight edge is placed against the posts 5 and 7 and secured astride the plate and projecting outwardly therefrom is a handle 15 formed of a length of wire bent. upon itself between its ends and having the extremities thereof outturned, as at 16, and arranged contiguous to the straight edge 12 at the center of the latter.. These out-turned ends '16. embrace the posts 5 and act to hold the plate 11 hingedly to the wire support 4. The deflector blades are indicated at 17, and, in the present instance, are four in number, and each blade 17 is formed with an irregular cross slot 18 at the center thereof, and this slot 18 opens onto one edge of the deflector blade, as clearly illustrated in Fig. 4 of the drawings. .The edge of the plate 17 contiguous to'the slot 18 is'formed with outwardly extending wings 19 arranged at opposite sidesof the slot 18, respectively.

In the use of the attachment, the support 4 to which the plate-'11 is connected is secured to the cage of the fan, .as previously described The slots 18 of the blades 17 are now slipped over the plate 11 and the wings 19 on the blades bent around the posts 5 and i 7, respectively, thereby pivotally connecting the blades to the posts- Inthe application of the blades to the posts the plate 11 is raised slightly by the handle 15, so that the to its original position, so'as to hold the blades 17 against swin 'ng movement on the. pivotally connected to said support and arposts. To adjust the lades the plate 11 is ranged side by side and capable of adjustraised and the blades swung relatively to the mentto different angular positions-to deflect plate 11 into ali 5 notches l4, and on the release of the plate blades being formed with irregular slots, rethe walls'of the notch bind against the corspectively, and a plate secured to said supresponding wall of the slots 18 in the respec-. port and disposed within said slots and havtiVe blades 17, owing to the'irregularities in ing. an irregular edge engageable in such the curved edge of the plate 11 and the slots slots to hold the blade in adjusted position.
