the art to which it appertains to make and use the same.

My 1nvent1on relates to lmprovements 1n fans and the object of my invention is toproduce a simple, cheap and very compact fan which will cause a thorough circulation of all the air in a room.

With this object in view my invention consists in the construction and combinations of parts as hereinafter described and claimed.

In the accompanying drawings: Figure 1 is a side view of my lmproved fan; Fig. 2 is a top plan view thereof; Fig. 3 is acrosssection of one of the fan blades taken on the line 33 of Fig. 1; Fig. 4 is a cross-section of one of the top fan blades and its support taken on the line ir-4 of Fig. 2.

1 represents a suitable base or support on which is vertically mounted a motor 2 of any desired type, 3' representing the revoluble shaft'of said motor. To the top of the shaft 3 is fixed a suitable frame 4, having extending arms 5, each of which is, at its outer end, provided with a flattened head 6 inclined to thedirection of the arm itself and projecting downwardly, as shown at 7 in Fig. 1. To each of the faces 6 is attached a fan blade 8 which is arranged vertically, the lower ends of the fan blades being connected to a wire or annular plate 9. From the construction shown it is apparent that the entire fan structure is hung upon the shaft 3 with the blades of the fan extending down around the motor 2.

As shown in Fig. 2 the fan illustrated is adapted to rotate clockwise and the leading edge of each fan blade is inclined outwardly to a slight degree and the trailing edge is inclined inwardly to a slight degreeas shown at '10 and 11 in Fig. 3, forming a reverse curve. To each of the arms is attached a horizontal deflecting blade 12. As shown in Fig. 4:, the bottomof this blade isat-- tached to the bottom of the arm by pins 13 and is then curved upwardly as shown at 14, so that, when the fan is revolved in the direction of. the arrow, the blades 14 will -Unlike the horizontally arranged fan, however, the blades do not throw a steady current of air in substantially a straight line but at each portion of their movement the blades 8 throw theair outwardly into the room, thus causing a rotary motion of the air and intime causing a thorough circulation of the air in a room, thus efficiently accomplishing the result aimed at by the ordinary swinging horizontally mounted fans.

I do not restrict myself to the exact form of fan blade shown, as blades of various shapes could be used. Furthermore the motor might be placed in and form part of the base, the blades being supported by a pedestal mounted above the motor proper, and other changes will suggest themselves to those skilled in the art.

I claim:

1. The combination of a support and a revoluble electric motor vertically mounted on said support and provided with an up wardly projecting shaft and a fan wholly supported on said shaft and provided with blades extending in a circle down and around said motor, and means for uniting the lower ends of said blades, substantially as described.

2. The combination of a support and an electric motor vertically mounted on said support and provided with an upwardly projecting shaft, spider arms sup ported by said shaft, and a series of vertically arranged fan blades, one end of which is secured to each spider arm, said fan blades extending downwardly around and below said motor, and means for uniting the lower ends of said fan blades, substantially as described.

3. The combination of a support and a motor vertically mounted on said support and provided with an upwardly projecting shaft, with horizontal spider arms secured to the upper end of said shaft, a series of vertically arranged fan blades, one of said blades being secured to each of said spider arms, said blades extending downwardly around and below said motor, and a ring uniting the lower ends of said blades, substantially as described.

4. The combination of a support and a vertically arranged electric motor mounted on said support and provided with an upwardly-projecting shaft, spider arms secured to the upper end of said shaft, a vertically arranged fan blade secured to each of said spider arms, a ring connecting the lower ends .of said fan blades and horizontal curved deflecting blades, one of which is secured to each of said arms, substantially as described.

5. The combination of. a support and a vertically arranged electric motor having an upwardly projecting shaft, a spider frame provided with horizontally projecting arms, said frame being secured to the upper end of said shaft, a series of vertically arranged fan blades, one of said blades being secured to each of said arms, a ring connecting the lower ends of said fan blades and located in a plane below the motor, and a series of horizontal curved deflecting blades, one secured to each of said arms, the vertical fan blades being each made of a reversely curved plate of metal, substantially as described.

In testimony whereof, I aflix my signature, in presence of two witnesses.
