UNITED STATES PATENT OFFICE.

OLEM BAILEY, OF KINSTON, NORTH CAROLINA.

AUTOMATIC FAN.

SPECIFICATION forming part of Letters Patent No. 313:,775, dated March 31, 1885.

- Application filed September 13, 1884. (No model.)

To all whom it may concern:

Be it known that I, OLEM'. BAILEY, a citizen of the United States, residing at Kinston, in the county of Lenoir and State of North Carolina, have invented certain new and useful Improvements in Automatic Fans; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure l of the drawings is a side view of my device. Fig. 2 is a top view of the same. Fig. 3 is a vertical sectional view, and Fig. 4 is a detail View, of one of the fans. Fig. 5 is a detail sectional view.

Theinvention relates to fans driven by clockwork or other mechanism; and its object is to make the two fan-blades attached to the device revolve around the center of their common axis and rotate on that axis simultaneously.

The invention consists in the construction and novel arrangement and adaptation of devices, as will be hereinafter more fully set forth and claimed.

In the accompanying drawings, A repre sents the box inclosing the clock-movement,

of octagonal or other proper form, and sustained upon the stand a by means of the perpendicular rod a, which enters a central vertical aperture in the stand, its upper end pass ing into the box, and is secured therein.

a is a central circular opening in the top of the box A, for a purpose hereinafter explained.

a is the removable bottom of the box, having proper opening in it for the passage of the rod a and for the arbor c, by which the clockmovement is wound up. The bottom a is attached to the box by means of the springs a a, fixed to the bottom and ascending within and engaging the sides of thebox, so that the bottom can be readily removed and replaced.

B is aplate-metal bridge fixed to the lower surface of the top of the box, diametrically across the opening a and having a central opening, b; and b is a crown-wheel of proper size above the upper surface of the bridge concentric with the opening o The said wheel has centrally in it an opening, b immediately above and corresponding to the opening I) in the bridge.

0 is the clock-movement, to the lower plate of which the rod a is secured, and c is the arbor by which the same is wound up.

0 is the wheel of the movement that engages the pinion d on the vertical shaft D, the upper end of which passes through the openings 6 in the bridge and crown-wheel b. The said shaft D has its lower bearing in any proper part of the frame of the movement.

E is a strip of metal plate fixed by a nut or otherwise to the upper end of the shaft D, immediately above the crown -wheel. The strip E has its ends bent upward.

e e are holes opposite each other in the upturned ends 6, for the passage of the axis F of the fan-blades. The upper ends of the branches e are turned horizontally outward above the holes 6, and have attached a horizontal ring, 6 for a purpose hereinafter explained.

F is the common axis of the fan-blades, passing horizontally through the holes a, and having fixed upon it, outside of oneof the branches, the pinion f, which meshes with the teeth of the crown-wheel b, and is rotated thereby, when the axis is revolved, by means of the clips e, the strip E, and the shaft D.

f is a collar or nut upon the axis F, outside of the other clip 6, and serving to keep the same central.

G G are the fan-blades, of oval or other proper shape, each of which has its handle or shaft 9 riveted in the outer end of a long sleeve, 9, the inner end of which is slotted longitudinally on opposite sides and bent inward, so as to spring and hold upon one of the arms of the axis F when the sleeve is pushed thereon. By means of these sleeves the blades may have their distance Varied from the center of motion.

H is a cap which fits down upon the ring 6 its edge passing into the opening of, and being slotted for the accommodation of the axis. The cap H prevents dust and dirt from getting into the device.

I is a hook pivoted to the side of the box A, which may be passed over one of the arms 1 of the axis F and stop the fans from moving, and 15 t are studs fixed upon the ends and projecting above the top of the box, upon which studs the fan-blades may be placed, when not in use, by means of the sleeves g.

t is a set-screw, by means of which the rod a may be set where wished'above the stand.

The operation of the device is evident from the foregoing description.

. Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination, with the box containing the operating mechanism, of the vertical rotary shaft D, having the plate E, provided with the vertical branches 6, attached thereto for supporting the shaft carrying the fanported on the vertical shaft, and the fan-shaft' F, supported in the vertical branches, and having thereon the pinion engaging with the crown-ratchet b, for rotating the same, substantially as specified.

' In testimony whereof I affix my signature in presence of two witnesses.
