FAN.

Specification of Letters Patent.

Patented May 19, 1908.

Application filed June 5, 1907. Serial No. 377,366.

To all whom t may concern:

Be it known that I, IDOLF A. YOUNGBERG, a citizen of the United States, residing at Tacoma, in the county of Pierce and State of Washington, have invented new and useful Improvements in Fans, of which the Afollowing is a specification.

This invention is an improved fan and motor for operating` the same, and it consists in the construction, combination and arrange ment of devices hereinafter described and claimed.

The object of my invention is to combine with a rotary fan a frame to support the same and a motor in such frame, such motor having manually operated arms whereby it may be driven to cause the fan to rotate.

In the accompanying drawings, Figure 1 is an elevation of the frame, the fan, the motor which drives the fan and the gearing which connects the motor to the fan. Fig. 2 is a similar view at right angles to Fig. 1. Fig. 3 is an elevation of the casing in which, in practice, the fan and its frame together with the motor are inclosed.

In accordance with my invention, I provide a frame 1 comprising spaced side pieces or standards 1a connected by upper and lower cross pieces 1b and 1C in which side pieces or standards a shaft 2 has its bearings. A rotary fan 3 is secured on one end of the said shaft and a pinion 4 is also secured to such shaft. A shaft 5 has its bearings in the said frame and is provided with a spur gear 6 which engages the pinion 4 and is also provided with a pinion 7. Said pinion is engaged by a gear 8 on a shaft 9. Said gear is lengaged by a gear 10 which is mounted on a shaft 11. On the opposite side of the said gear 10 are drums 12-13 which revolve independently of said gear 10 and of each other and which are respectively provided at the ends nearest said gear with ratchet wheels 14-15. The said gear 10 is provided on opposite sides with spring pressed pawls 16 Which respectively engage such ratchet wheels.

At the lower end of the frame 1, isa Vfixed operating lever 17, and a pivotally mounted o erating lever 18, the latter being piyoted to t e former, as shown at 19. The said lever 18 is provided with oppositely extending arms 20 and 21. Such arms of the lever 18 have the ends of a cord 22 attached thereto, the said cord being partly coiled on the drum 12. A similar cord 23 which is coiled in the op osite direction on the drum 13 has its ends secured also to such arms 2O and 21. Said levers 1718 are provided on their outer sides with eyes or loops 24 through which a thumb and iinger may be inserted and a spring 25 is mounted between the said levers and serves to force lever 18 away from lever 17. The lever 18 may be pressed against the tension of the said s ring toward lever 17 and then relaxed to alow it to be moved in the reverse direction by the spring, and hence such levers may be caused to oscillate to impart corresponding motionto the arms 20 and 21 and hence cause the cords 22e-23 to be moved simultaneously in opposite directions to cause the drums to turn in opposite directions, each drum being thus caused to turn first in one direction and then in the reverse direction. Since the ratchet wheels turn with the drums and are connected to the master gear 10 by the spring pressed pawl, 16, it is evident that such oscillating motion of the operating lever will cause such master gear to be continuously revolved in one direction and the fan, being geared to the motor, will be also driven in one direction.

The frame 1, together with the motor which it contains will preferably, in ractice, be inclosed in a casing 26, such as s iown in Fig. 3. Such casing has a hinged door 27 on one side to admit of access to the motor and also has an opening 28 to clear the fan, a`

ter gear and each having a ratchet wheel,

said drums being disposed on opposite sides of the master gear and between the same and said standards, spring-pressed pawls carried by the gear and engaging said ratchet wheels, lever mechanism supported by the base of the frame and spring-actuated in one direction, a bow actuated by said lever mechanism and arranged below said gear and drum and having arms extending in opposite directions through the frame in opposite directions beyond the drums, and cords artly wound on the drum and connected to the oppositely extending armsy of the bow, said cords being wound reversely on the respective drums. i

2. A portable hand-operated fan comprising a frame including spaced side pieces or standards and a base piece connecting the same, a driving motor including a gear jour-v naled between said standards, spring-pressed pawls carried thereby, drums disposed on opposite sides of said gear and between the same and the standards, said drums being revoluble independently of the gear and of each other and having ratchet wheels engaged by said pawls, relatively stationary and movable levers at the lower end of the frame, the stationary lever being supported by the base piece of the frame, a bow carried by the movable lever and having oppositely extending arms rojecting below the drums and through the ame and in opposite directions beyond the same, a spring for actuating the movable lever in one direction, and cords attached to the oppositely extending arms of the bow and to the drums and wound in reverse directions on said drums.

In testimony whereof, I afIiX my signature in presence of two witnesses.

IDoLF A. YOUNGBERG.
