4 Claims.

An object of my invention is to provide means for supporting a. fan structure, such means being extremely simple and inexpensive to manufacture.

A further object is to provide supporting means for a fan structure including partially the wire guard for the fan blades having a pair of laterally spaced feet adjacent the bottom thereof and partially a third support comprising a foot member mounted on a yoke or leg memher which is pivoted relative to the fan guard and thereby operable to permit inclination of the guard and thereby the fan at different desired angles, said yoke or leg member being also svvingable to a non-projecting position for shipping or storing purposes, and to another position where it serves as a support for suspending the fan structure on a wall hook or the like.

Still a further object is to provide inexpensive supporting means for a fan structure which may be formed of or secured to the guard for the fan blades, thereby eliminating the necessity of the usual base and supporting post for the motor, the motor in turn ordinarily supporting the fan guard.

With these and other objects in View, my invention consists in the construction, arrangement and combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawings, in which:

Figure 1 is a side elevation of a fan structure with my supporting means applied thereto.

Figure 2 is a sectional view on the line Z-2 of Figure 1.

Figure 3 is a side view showing the fan ad'- justed for support on a vertical wall.

Figure 4 is a rear elevational View with the parts of the structure in the position "of Figure 3.

Figure 5 is a view of the lower portion of Figure 4 showing a slightly modified construction. I

Figure 6 is a view similar to Figure 2 showing a variation of the invention.

Figure '7 is a rear elevational view of a modified form of my fan structure and its supporting means.

Figure 8 is a side elevation thereof showing the fan supported on a table or the like; and

Figure 9 is a similar view partly in section showing the fan supported on a wall.

On the accompanying drawings I have used the reference character M to indicate a motor.

Fan blades F are mounted on the shaft I ii of the motor for rotation thereby. A guard G is provided for the fan blades F and is preferably formed of wire elements spot-welded together. The design of these elements may vary greatly and forms no part of my invention, the main consideration being that the guard G safely enclose the fan blades F againstaccidental contact of the users person therewith. The guard G is illustrated as being secured to the motor M by bolts i2 and nuts l3.. 1

The supporting means for the elements M, F and G are the novel features of my present invention. Instead of providing the usual base and supporting post for the motor, I utilize the guard G for at least partially serving as a support, thus eliminating expensive parts of the usual construction and thereby effecting an economy in manufacture. I

As one method of forming feet on the guard, I provide a pair of laterally spaced ring elements l4 secured as by spot-welding indicated at 15 to the lower portion of the guard G. Specifically the guard has a peripheral wire l6 and as shown in Figure 4, I secure the rings M thereto. Each ring has mounted therein a foot I? formed of rubber or other resilient material to contact with a table top or the like and thereby prevent scratching the table.

The two feet ll are laterally spaced and a third foot Ha serves to provide a three-point support for the fan structure. The foot Ila is shown in section in Figure 3. The foot Ila is mounted in a ring element Ma which is secured as by spotewelding 15a to a yoke member [8.

The yoke member 18 is formed of wire and has a pair of ears I!) encircling a friction rivet 20 and a clamp bolt 2! as shown in Figure 4. Stationary ears 22 also encircle the rivet and bolt and are formed on arm members 23. The arm members 23 are spot-welded as at 24 and 25 to portions of the guard G and are thereby rigidly secured to the guard.

A wing nut 26 is mounted on the clamp screw 2| whereby the yoke Hi can be retained at different angles relatives to the plane of the guard G and the fan may thereby be tilted for delivering air parallel to the table top on which it is supported or at difierent angles of inclination relative thereto.

The rivet 2B and the clamp screw 2! are mounted on opposite sides of the motor M and the yoke I8 is swingable to a position over the motor as shown in Figure 3 so that the bushing l'la can be hooked on a nail or wall hook 2'! whereby the fan may be suspended on the wall. Here again it is possible to change the inclination of the fan as desired due to the pivoted connection between the yoke l8 and the guard G and the possibility of keeping the parts in any desired position by tightening the wing nut 28.

To further reduce the expense of manufacture, the ring elements M can be eliminated and foot elements 28 formed directly on the circumferential element lfia of the fan guard, as shown in Figure 5. Since these foot elements are formed with a rounded lower surface and can be made of plated or polished wire, the rings M and the resilient means such as the feet ll can be dispensed with. As shown in Figure 6 if desirable a length of rubber tubing 28 may be mounted .on the yoke member E8 to take the place of the foot lid and contact with the table surface.

As shown by dotted lines in Figure 3 it is possible to swing the yoke member l8 to a nonprojecting position relative to the fan structure whereby to facilitate shipping of the fan and storage thereof when not in use. This is a desirable feature from the standpoint of economizing on the space necessary for the fan when storing or shipping it.

In Figures 7, 8 and 9 I show modified structures in which eye-shaped foot elements 28a are formed as shown in Figure 8, and secured to the peripheral wire i617 of a guard G as by spot-welding indicated at 30. Instead of the yoke member 18, a leg member 18a is illustrated which is pivoted relative to the guard G by a clamp bolt 21a. The clamp bolt 21a extends through a clamp band 3| around the motor lvl whereby the clamp screw Zia is carried indirectly by the guard instead of directly thereby as shown in Figure l. The leg member lBa may be formed of flat bar stock with tubular eyes 32 and 33 formed at its ends. The eye 32 receives the clamp screw Zia, while the eye 33 serves as a rounded surface to engage the table top T. Adjacent the eye 33 a perforation 3 3 is provided for receiving the wall hook 21a when the fan is to be hung on the wall as shown in Figure 9. The dotted. position in this figure shows the leg member l8a folded to a non-projecting position for shipping or storage purposes.

The pivoted supports E3 or Isa ofmy fan structures serve as means to adjust the inclination of the fan whether resting on the table or suspended on the wall. Thus an adjustment is secured without the necessity of going to an expensive construction involving a base, a supporting post and a pivotal support between the post and the motor. The guard of my invention in each instance serves partially as a support when the fan structure is resting on a table or other supporting surface, and the pivoted leg or yoke member serves in conjunction therewith to provide a complete three point support for the structure. The leg or yoke member may be readily adjusted to secure projection of the air at any desired incline.

Some changes may be made in the construction and arrangement of the parts of my supporting arrangement without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims any modified forms of structure or use of mechanical equivalents which may be reasonably included within their scope.
