CEILING FAN.

Application filed November 8, 1921. Serial No. 513,806.

17'0 all whom it may concern:

Be it known that I, MAURICE M. GLAssEn, a citizen of the United States, and a resident of Charleston, in the county of Charleston and State of South Carolina, have invented.

certain new and useful Improvements in Ceiling Fans, of whichthe following is a specification.

My invention relates to motor operated fans and particularly, although not necessarily, to ceiling fans, a purpose of my invention being the provision of a ceiling fan which provides simple and efficient means for effecting the bodily oscillation of the fan wheel whereby vthe air current pro'- duced by the fan is continuously diffused over a constantly changing area.

I will describe'one form of fan embodying my invention and will then point out the novel features thereof in claims.

In the accompanying drawings:

Figure 1 is a view showing in perspective one form of fan embodying my invention.

Figure 2 is a transverse sectional view looking downwardly. y

Figure 3 is a view similar to Figure 2 looking upwardly. y

kFigure 4f is a fragmentary sectional view of a portion of the gearing comprised in the fan shown in the preceding views.

Similar referencecharacters refer to similar parts throughout the several views.

Referring specically to .the drawings and particularly to Figure 1, my invention -in its present embodiment comprises a pipe or standardyAradapted to be lsuitably fixed at its upper end to the ceiling to provide a support for the entire fan,.this standard carrying at its lower end a cup-shaped head I-I in` which is sustained an internal ring gear G, as clearly shown inFigure 3. At a point above the head H, the horizontal portion 15 of a yoke Y is secured, the parl allel or verticalk portions 16 of the yoke being provided at their free ends with ears 17 that may be secured to or formed integrally with the upper section 18 of a socket member S. The socket member S consists of the upper section 18 and a lower section 19, the latter being also provided with ears 2O which are adapted to aline with the'ears 17 and to be secured thereto by fastening members 21 such as screws, bolts or the like. Each section consists of a ring the inner surface of which is concaved to, cooperate with the other ring in providing a socket for the reception of aV ball. By virtue of the ears 17 and 20, the two sections are securely held in socket formation and rigidly sustained upon the standard A byv means of the yoke Y. 'Adapted to work within the socket mem ber S is a ball member B which constitutes the casing of a motor M as shown in dotted lines in Figure 1. The lower "end of the motor shaft projects beyond' the casing or ball member B and is there provided with the usual fan wheelF. The upper end of the motor shaft which is designated at 22 is operatively connected to a counter-shaft 28 through the medium of a reduction train of gearing designated generally atl D. rIhe reduction gearing D is housed in a casing K and may be of any suitable vform so long as the vrotation of the countershaft is sufficiently reduced with respect 'to the rotational speed of the motor shaft to elfect the desired rotation of a pinion P fixed to the upper end of the counter shaft. Because of the distribution of weight, the ball 1nember B normally occupies the position shown in Figure 1 wherein the fan wheel F -is inclined with relation to the horizontal and the counter-shaft 23 is inclined with relationto the vertical so that the` pinion P at all times meshes with the-ring gear G. When the motor operates, the fan wheel F is caused to rotate and upon the driving of the counter-shaft 23 rotation of the pinion I is effected which causes it to traverse the path defined by the-ring gear G. Under this movement, the ballmember B is caused .to rotate about a lvertical axis or an axis defined by the standard A, and under such movement the fan wheel F during its rotation by the-motor M is also caused to oscillate. By virtue of this movement of the fanl wheel a diffusion ofy the air current produced continuously occurs over a constantly changing area. y

' It is to be lunderstood that the movement of the ,ball member B can be varied depending `upon Ithe particularform of the gear G. For example, the gear G may be of star formation or elliptical so that with the pinion P constantly meshing therewith a corresponding movement of the ball member B is effected which in turn causes the same movement of the fan wheel F.

An important feature of my invention is CII lil

the simplicity of construction of the fan, it being manifest that the ball and socket members as ivell as the pinion and gear can be readily lubricated so as to insure of the smooth and unrestricted operation of the fan. The socket member spa-ns the greatest diameter of the ball member, but being formed of two sections permits removal of the ball member by a detachment of the lower section 19.

It is desirable that the movements of the ball shaped motor casingB relatively to the socket S be restricted to movements which ivill not result in twisting or straining to the point of rupture the electrical conducting Wires leading to the motor casing. When electrical conducting Wires, such as indicated at U, are operatively7 attached to the motor, it is essential that the ball shaped casing B be held against complete rotation in the socket while permitted to oscillate in the manner described. To this end, the socket S has formed in its inner ivall an obliquely extending or inclined groove, in-

i dicated generally at 24. which groove is formed in the inner walls of' both sections of the socket. A projection 25 on the outer ivall of the ball shaped motor casing is very loosely received in the groove 24 and coacts with the latter to prevent the complete rotation of the motor casing relatively to the socket ivhile permitting oscillatory movements of the former about varying axes. The projection 24 may be the head of a set screiv fast in the motor casing B as shown.

Although I have herein shown and described only one Jform of fan embodying my invention, it is to be understood that various changes and' modifications may be made herein Without departing from the spirit of the invention or the spirit and scope of the appended claims.

What I claimis:

l. A fan comprising a supporting yoke, a socket carried by the yoke, a motor casing or spherical form mounted in the socket, a motor shaft extending from the casing, a fan Wheel on the shaft, a counter-shaft operatively connected to the motor shaft, a gear fixed to the yoke, and a pinion on the counter-shaft and constantly meshing With the gear whereby said gear operates to move the motor casing relatively to the socket With a resultant oscillation of the fan Wheel.

2. A fan comprising a stationary yoke, a socket fixed to the yoke, a motor casing of sphericalI form movably mounted in the socket, a motor in the casing, a fan Wheel operable by the sha-ft of vsaid motor, and

means operable by the motor for moving the casing relatively to the socket with the resultant oscillation of the fan Wheel.

3. A fan comprising a stationary yoke, a socket fixed to the yoke, a motor casing of spherical form movably mounted in the socket, a motor in the casing, a fan Wheel operable by the shaft of said motor, and means operable by the motor for effecting movement of the motor casing to cause a predetermined bodily movement of the fan Wheel during its rotation by the motor.
