SPECIFICATION forming part of Letters Patent No. 751,484, lated February 9, 1904.

' Application iiled April 2, 1903. Serial No. 150,802. (No model.)

To a/ZZ whom it may concern:

Be it known that I, CHARLES A. Een, a subject of the King of Sweden and Norway, and a resident of Belleville, inthe county of Es- '5 sex and State of New Jersey, Vhave invented certain new and useful Improvements in Fans, of which the following is a specification.

My invention relates generally to lfan-motors, and has more particularly reference to ro means for oscillating the said motoras it rotates.

I shall describe an oscillating fan-motorembodying my invention and afterward point out the novel features in the claims.

'15 The object of my invention is to produce an4 oscillating fan whose action will Abe positive at all times and one, furthermore, having an adjustment whereby no oscillation will take place unless so desired.

- A further object resides in constructing the parts so that the fan can be adjusted with relation to the base without interfering with the oscillation of the fan.

To this end my invention comprises the 2 5 hereinafter-described features of construction and combination of parts.

In the drawings I have embodied my invenvention in suitable forms, but .do not wish to be understood as limitingmyself to these par- 30 ticularforms.

In the said drawings, Figure l is a rear view of a fan embodying my invention with a section through part of the driving mechanism on the line x x of Fig. 2. Fig. 2 is a side view Figs. 3 and 4 show modifications. Similar letters of reference indicate corresponding parts in the different views.

A indicates a fan-motor of any suitable construction, but preferably adjustably secured on the hollow base B by suitable means, as the socket b', carried by the said base and the corresponding ball a', forming together a joint by means of which `the fan .can be tipped or adjusted to different positions at an angle to the base. This said base B is split, as at 52, and provided with the tightening device b3 to hold the fan securely after it has been adjusted to the desired position.`

The ball a is provided with an extension a2,

a, made, preferably, of vulcanized ber matearm a carries a pin c55, entering the slot co5,

lby causing the segment 020 to oscillate the fanthe said ball and extension being provided with a vertical passage a3, formed with wa seat a4. Resting upon the balls a5 in this seat is a hollow spindle a6, carrying the fan-motor A, which in this way is mounted to turn.

The fan-motor carries upon its armatureshaft co7 a worm as, engaging with the worinwheel a. Mounted in the bearing am is a shaft al? at right angles to the armature-shaft. Upon this shaft is located a disk 012, carrying a'bushing @13 and provided with a slot a, open at one end @15. rIhe worm-wheel a is mounted in the bushing L13 and is interposed between two very thin insulation disks 016 and rial, which, with the worm-wheel, are held up against the slotted disk am by meansv of the springs am on thebushing al?, the resultant friction being sufiicient to rotate the disk a with Vthe Worm-wheel a, Mounted in the 7o framework of the motor and upon the pin am `1s asegment a2", provided with an arm-a21 and.

engaging with a spiral w22, liXed to the extension a2 ofthe ball a by means of the screw 60", so that the s'aid spiral isXed with the base. The

having an aperture am, of the rod (L23, which is loosely connected with a block a2* at its other end, which in turn is adjustable in the slot a by means of the screw andholes am.V From this it will be understood that the rotation of 'the armature-*shaft t7 causes the worm t8 to impart its motion to the worin-wheel co9, which in turn by frictionrotates the disk @12, there- 8 5 motor by engaging with the fixed spiral 622. By adjustingthe position of the block a2* the distance of theoscillation can be varied, or the oscillation can be entirely obviated by moving the block f4 to the center of the disk 012. The speed of the oscillation will of course depend on the speed of the rotation of the fanmotor. In case the block L24 is placed central of the disk @12, as noted above, the rotation of the worm-gear anddisk will of course continue, though no oscillation will takeA place, and incase the fan-motor should by accident encounter any obstruction as it turns from side to side the result would not in any way stop the rotation of the motor or disturb the IOO operating parts, as the worm-wheel would continue to rotate, while the disk (i12 would remain stationary, owing to the fact that the said disk is operated by friction only. The motor is thus oscillated positively by the means set forth, which are operated by the rotation of the armature-shaft, and the oscillating means except the fixed gear on the ball a' oscillate with the fan-motor. In order that the wiring may not interfere with the proper operation of the means of oscillating the fan, the wires C are carried up through the hollow base B, through the passage a3, hollow spindle a, through the opening a2 in the latter, and through the passage @27 to the field-coils c'.

In Fig. 3 is shown a modification in which I employ a rack (t28 and pinion 629 in place of the spiral and segment shown in Fig. 2. In Fig. 4 I have shown still another modification in which I employ a bevel-gear ai and a bevelsegment am.

Othermodiiications could of course be used.

Vhen it is desired to have a non-oscillating fan and to adjust the fan-motor around its axis with relation to the base, the pin 655 is disengaged from the aperturea57 and allowed to rest loosely in the slot a5, the block a2* having previously been placed central of the disk c, as hereinbefore explained. This permits the fan-motor to be adjusted by turning the spindle a, which is then secured in position by the screw @58. When it is desired to have the fan oscillate again, the screw w58 is loosened and the block a2* moved away from the center of the disk am. The action of the motor will then move the rod @23 until the pin 1,55 enters the aperture am, when the motor will commence to oscillate again.

Having thus described my invention, what I claim isl. The combination with a base, of a fanmotor, a spindle mounted to turn on the base carrying the said motor, an armature-shaft on said motor, a worm carried by the same, a worm-wheel engaging with said worm, a gear stationary with the base, a gear moving with the fan-motor engaging with the first-mentioned gear, a friction-disk moving with the worm-wheel, and a rod connecting the friction-disk with the gear moving with the motor, whereby the rotation of the armatureshaft causes the spindle carrying the fan-motor to oscillate.

2. The combination with a base, of a fanmotor, a spindle mounted to turn on the base carrying the said motor, an armature-shaft on said motor, a worm carried by the same, a worm-wheel engaging with said worm, a spiral stationary with the base, a segment moving with the fan-motor engaging with the spiral, a friction-disk moving with the wormwheel, and a rod connecting the friction-disk with the segment, whereby the rotation of the armature-shaft causes the spindle carrying the fan-motor to oscillate.

3. The combination with a base, a fan-motor, a spindle mounted to turn on the base carrying the said motor, an armature-shaft on said motor, a worm carried by the same, a worm-wheel engaging with said worm, a gear stationary with the base, a gear moving with the fan-motor engaging with the iirst-mentioned gear, a friction-disk moving with the worm-wheel, and a rod connecting the friction-disk with the gear moving with the motor and adjustably secured to the said frictiondisk, whereby thc rotation of the armatureshaft causes the spindle carrying the fan-motor to oscillate.

4. The combination with a base, of a fanmotor mounted to turn upon the said base, an armature shaft carried by the motor, and means for oscillating the said motor with relation to the base comprising in part: a worm carried bythe armature-shaft, a shaft located at right angles to the armature-shaft, a friction-disk having' a bushing' on said shaft, a worm-wheel and two insulation-disks between which latter it is interposed on said bushing, the worm wheel engaging with the worm aforesaid, and springs on said bushing for keeping the worm wheel and composition disks in contact with the friction-disk whereby the said friction-disk moves with the wormwheel.

5. The combination with a base and fan-motor having an armature-shaft and mounted to turn with relation to the base, of means for oscillating the said fan-motor from the armature-shaft of same comprising: a gear fixed with relation to the base, a segment engaging with the same mounted on the fan-motor, an arm and a pin on the segment, a rod having a slot with an aperture for the reception of the pin of the segment, and gearing' connecting said rod with the armature-shaft of the motor.
