' El Calvario, Havana, Cuba Application June 15, 1953, Serial No. 361,758

2 Claims. (Cl. 230-259) This invention relates to a fan, and more particularly to a portable battery operated fan.

The object of the invention is to provide a fan which is small enough so that it can be conveniently carried around in a persons pocket or other location when it is not being used.

Another object of the invention is to provide a pocket electric fan which is adapted to be driven by batteries and a suitable motor, the fan adapted to be carried in a suit pocket or ladys purse when it is not being used or wherein the fan can be readily placed on a table or desk or the like when it is to be used.

A further object of the invention is to provide a portable battery operated fan which is extremely simple and inexpensive to manufacture.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings, forming a part of this application, and in which like numerals are used to designate like parts throughout the same:

Figure 1 is a front elevational view of the fan, constructed according to the present invention.

Figure 2 is a front elevational view of the fan, with the blades in folded or collapsed position, as when the fan is to be carried in a persons pocket.

Figure 3 is a rear elevational view of the fan, with parts broken away and in section.

Figure 4 is a sectional view taken on the line 4-4 of Figure 1.

Referring in detail to the drawings, the numeral designates a housing which may be made of any suitable 4 material, and the housing 10 includes spaced parallel vertically disposed side walls 11 and 12, and a horizontally disposed top wall 14. A partition 15 is arranged in the housing 10, and the partition 15 defines an upper compartment 16 and a lower compartment 17, Figure 4.

A motor 18 is supported in the upper compartment 16, and a plurality of batteries 19 are supported in the lower compartment 17.

Extending across the tops of the batteries 19 is a bar 20, and a bolt and nut assembly 21 which provides a contact leads from the bar 20. A wire 22 may lead from the motor 18 to the contact 21, and a second wire 23 leads from the motor 18 to a switch 24. The switch 24 may be provided with a manually operable button 25 for controlling actuation of the motor 18, and a ground wire 26 leads from the switch 24 to the casing 10.

A shaft 28 extends from the motor 18 through an opening 29 in the front wall 27 of the housing 10, and a sleeve 30 is spaced from the end of the shaft 28 and is secured thereto by a set screw 31.

Mounted on the outer end of the shaft 28 is a collar 32, the collar 32 being secured to the shaft 28 by a set screw 33. Interposed between the sleeve 30 and the collar 32 and rotatably and slidably mounted on the shaft 28 is a plurality of rings or collars 35, 36, and 37. A first blade 34 is secured to the collar 32 so that as the shaft 28 rotates the blade 34 will rotate therewith. Secured to each of the collars 35, 36, and 37 is a blade, and these blades are indicated by the numerals 38, 39 and 40. This construction permits the blades to be folded one behind the other as shown in Figure 2 so that the fan will occupy a minimum amount of space as when it is to be carried in the pocket. It will be seen that there is sufficient space or clearance between the sleeve 30 and the collar 32 to permit the blades to be folded in the position shown in Figure 2. Normally when the motor 18 is actuated, the blades will move outwardly as shown in Figures 1, 3 and 4 due to centrifugal force.

A means is provided for causing the blades to rotate simultaneously when the motor is actuated. This means comprises a lug or pin 41 which is secured to each of the blades 38, 39, and 40. These lugs 41 are so placed that when the motor 18 is actuated the lugs 41 will catch on or engage the next succeeding blade to thereby cause all of the blades to rotate in unison.

A suitable stand 42 may be provided for supporting the fan on a table, desk, or other location. It is to be understood that although the fan of the present invention is illustrated as having four blades, the number of blades can be varied as desired.

From the foregoing it is apparent that a fan has been provided which can be operated by batteries such as the batteries 19. When the switch 25 is actuated manually, the electric circuit leading from the batteries 19 to the motor 18 will be completed whereby the shaft 28 will be rotated. As the shaft 28 is rotated the blade 34 will rotate therewith and the lugs 41 will cause each of the blades 40, 38 and 39 to also rotate so that the blades will occupy the position shown in Figures 1, 3 and-4. When the fan is not being used, the switch 25 is turned 01f so that the shaft 28 stops rotating. At this time the blades 34, 39, 38 and 48 can be folded one behind the other so that they occupy the position shown in Figure 2 whereby the fan can be readily carried in a pocket or other convenient location.

The present invention does not require an outlet from an electric source since it is operated by the batteries and the pocket fan is very small, easily handled and operated.

The fan may be carried in a suit pocket, ladys purse, or the like, and it has the stand 42 so that the fan can be placed on a vanity table while making up, or on a desk or working table. It may also be used in a movie house, at boxing matches, baseball games and the like. The blades each have an independent action and only the blade 34 is rigidly secured to the shaft 28. When the motor is started the blade 34 which is connected to the shaft 28 connects with the next succeeding blade by means of the coupling pin 41 and drives the next succeeding blade and this blade in turn engages with the coupling pin on the next blade and drives it and so on until the fan is in operation. When it is desired to stop the fan the switch 24 or 25 is turned off and the blades by their own weight are alined vertically. If the blade 34 which is connected directly to the motor shaft 28 remains upright, it is a very simple operation to move it down with ones finger so as to fit better in ones pocket or purse.
