ELECTRIC FAN.,

SPECIFICATION forming part of Letters Patent No. 696,052, dated March 25, 1902. Application tiled January 15, 1901. Serial No. 43,363. (No model.)

To ad whom it may concern:

Beit known that l, WALTER JOHN HUBERT JONES, a subject of the Queen of Great Britain, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Electric Fans, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this speciiication.

My invention relates to rotary fans of the character ordinarily operated by an electric motor, and has for its object the provision of means whereby the fan may have imparted to it, in addition to a rotation on its axis, a bodily movement of rotation in a horizontal plane, so as to direct a current of air toward every desired part of the room or apartment which it is desired to ventilato.

It also has for its object the provision of means whereby the fan may be bodily rotated through any desired arc of a circle and automatically reversed at the desired end of its movement in each direction.

It also has for its object, broadly, the provision of means whereby the above-described objects may be attained, but which will at the same time permit the fan to be adjusted at any desired angle to the horizontal.

It also has for its object the arrangement of the motor and the immediate driving means I'or bodily rotating' the fan within separate inclosures.

The invention consists of the hereinafterdescribed mechanism for obtaining the abovementioned objects and in the general arrangement of the same.

In the drawings, Figure l is a side view,

partly in section, of the entire mechanism..

Fig. 2 is an end view, partly in section, of the same. Fig. 3 is a plan view of the mechanisnn for imparting a bodily movement of rotation to the fan. Fig. 4 is an enlarged plan view of the motor with one of the field-magnet coils removed. Fig. 5 is an enlarged detached view of the brushes and brush-holders. S is an enlarged detail view of the levers operated by the stops. Fig. 7 is a diagrammatic view of the motor, resistance-switch, and electric connections.

A is the fan, and c the shaft thereof,which also carries the armature b2 of the drivingmotor.

I) h are the coils of the field-magnet of the motor, one coil being secured to the lower half c of the casing, while the other coil is secured to the upper half c' of the casing. The upper half of the casing is hinged at c2 to the lower half.

d cl are the bearings for the shaft, the same consisting of a ball-and-socket joint, the socket being formed by the opposing parts of the halves of the casing.

c c are the commutator-brushes, inserted loosely in pockets formed partly in the upper half and partly in the lower half of the casing. Each pocket is formed with an'inner lining of brass j' and an outer wall of insulating material f, such as fiber.

g g are springs bearing against the brushes and holding 'them in contact with the armature.

By swinging up the upper half ol` the casing on its hinge ready access is afforded to the internal parts of the motor, to the bearings, and to the brushes. The brushes can thus be expeditiously renewed.

I'I is the base of the machine, and I the immediate support for the motor-casing,the support I being adapted to revolve in a horizontal plane over the base II by means to be hereinafter described. The lower half c of the casing has projecting from its base alug c3, extending between lugs t" i2, projecting from the top of the support I. Extending through lugs c3, t, and 'i2 is a bolt i3, having a holding-nut it. By means of these devices the motor-casing and fan may be adjusted at any desired angle to the horizontal and held securely in their adjusted positions.

The support I and the upper part of the base II form a casing or inclosure which contaius the driving mechanism for imparting the desired movement of bodily rotation or reciprocation of the fan on a vertical axis. The driving mechanism will now be described.

Secured to the support I is the shaft i5, which extends down through the inclosnre and has its bearing in the base H.

7s is a bracket depending from the top of the support I, said bracket having bearings for the shaft of the worin K and bearings for IOO the shaft of the worm-,wheel K. The wormwheel K' is in driving engagement with the worm K, which ris the immediate driving power for the inclosed driving mechanism and which is driven by the means hereinafter described. Secured to the shaf t of the wormwheel K" is a bevel-Wheel' K2, which may be either a gear-wheel or a friction-wheel.

Zis an arm depending from the top of thev bracket lo.

Z' is a shaft turning in bearings in arm Z.

L L' are bevel-Wheels on the shaft Z'. By sliding the shaft either bevel-wheel L-or L' may be brought into driving engagement with the bevel-Wheel K2, thereby rotating shaft Z' in one direction or the other.

L2 is aspur gear-pinion securedto one end of the shaft Z', said pinion engaging a circlilar rack H', secured to the base H.

It will be readily understood that by imparting a movement of rotation to the Worm K Athe shaft Z' is driven in one direction or the other, and as th'e pinion L2 on the end thereof is in engagement With the fixed rack H' the shaft Z' will have imparted to it a bodily movement of rotation in a horizontal plane about the axis of the circular rack H', thereby imparting a similar movement to the entire inclosed driving mechanism, the support I, the motor-casing, motor, and fan. In other words, the entire machine above the stationary base H will be rotated in a horizontal plane. The support I has an annular rim i, which contacts with annular projections h and h on the base H.

In order to drive the worm K, I provide a iexible shaft M, connecting the armatureshaft and the shaft of the worm, said flexible shaft extending through an orifice in the support I.

I provide the following means forautomatically reversing the rotation of the fan, motor, and support.

N is a lever secured between its ends to pivot n, rotatably supported by the bracket la. One end of lever N extends outwardly through support I, While the other end is connected to shaft Z'.

N2 is a leaf-spring secured to the lever N, said spring engaging a pin N2, secured to the bracket 7c. The spring N2 holds the lever N firmly in the illustrated position, thereby holding the bevel-wheels L' and K2 in engagement.

Secured to theannular rim h are stops O O in line of travel of the lever N. After the machine is started the leverN will in itsV movement in one directionengage one of the stops O, thereby turning it on pivot n and sliding the bevel-wheels L and L', with their shaft Z', disengaging Wheel L' from 'wheel K2 and causing the spring N2 to slip over the pin N3. As soon as the spring engages the opposite side of the pin it will 4 quickly turn the pivot n still farther and move the wheel L into engagement with wheel K2. The ma.-

chine now rotates in the reverse direction until lever vN: engages the otherstop O,wh ich again reverses the machine.v The stops O are adjustable along the rims h and are held in their adjusted position by means of the,

holding-screws 0.

The resistance-coil P is located within the base H, and under the resistance-coil is a switch Q. The in-feed and out-feed Wires R R of the circuit extend from the resistance-` coil up through the top of the base and` are then connected, respectively, to the annular contact-plates S S.

T T are brushes secured to arm Zand contacting, respectively, vwith the contact-plates S S. Fromthe brushes T T the wires R R lead up through the support I and motor-casing to the motor. l

For thev fiexible shaft M may be substituted any .other device which will permit the fan to be adjusted Without disengaging the driving connection between the armatureshatt and the worm K. Nor do I limit myself to any otherof the specific devices hereinbefore described, except wherein such devices are expressly claimed, as it is .obvious that various details of structure may be modified Without departing from the invenl tion.

Having now fully described my invention, whatI claim, and desire to protect by Letters Patent, is

1'. The combination, with the fan, of a mo' tor for imparting thereto a movement of rrotation about its own axis, driven mechanism for rotating the fan bodily about a vertical axis, adjusting means for setting the fan and motor at different angles to the horizontal and a driving connection, independent of the fan, adapted to be maintained in engagement Ywith the motor and the driven mechanism at dierent adjusted positions of the fan and motor. f

2.
