ROTARY FAN.

Application filed December 6, 1913.

To all whom it may concern Be it known that I, VVAsABURow TAKE- SUYE, a subject of the Emperor of Japan, residing at Ogden, in the county of l/Veber and State of Utah, have invented new and useful Improvements in Rotary Fans, of which the following is a specification.

The invention has for one of its principal objects to enable the incorporation of a manually operated rotary fan in the handle of a sunshade, whereby in sultry weather, not only may the handle be manipulated to shield the user from the sun, but by a simple movement of the fingers which will not interfere with the grasp on the handle, a rotary fan on the side of the handle may be used to produce a cooling breeze.

A further important aim is to simplify the construction of the frame for the mechanism and the method of mounting it whereby it is adapted peculiarly for the present use.

A further important object is to present such an arrangement of the parts that a symmetrical casing may inclose them in a form and size which will be without objections as a part of an umbrella or the like.

. Additional objects and advantages will appear, some of which will be apparent from the following description and from the drawings, in which,

Figure 1 is a side view of a sunshade having a handle constructed in accordance with my invention, Fig. 2 is a detail longitudinal sectional view of the mechanism. Fig. 3 is a side view of the mechanism and frame, the casing in section, Fig. 4C is a cross section of the handle. Fig. 5 is a detail of the handle showing the method of use. Fig. 6, is a detail of a modified hand rest,.showing a hand engaged therewith, Fig. 7, is a detail of the ferrule structure at the upper end of the frame, Fig. 8, is an outer end view thereof, Fig. 9, is a fragmentary view of a handle of modified construction.

There is illustrated a sunshade or umbrella 10, of any usual construction as re gards the canopy and supports, the handle 11 of which, however is preferably attached to the stem by means of a screw threaded shank 12. The handle may approximate the proportions of the usual umbrella or parasol handle, and comprises a symmetrical grip 13 in which there is secured the two sides of a frame 1& which comprises two pieces of thin strap metal suitably spaced Specification of Letters Patent.

and apertured for the mounting of a train of gears to be described in detail, the upper ends of the pieces being inset rounded and threaded for engagement in the stem of the umbrella. A shaft 16 is mounted revolubly closely adjacent the upper end of the frame 1 being carried in suitable apertures in the side pieces thereof, and a small gear 17 is secured thereon. The shaft has a squared end projecting through the frame, upon which the correspondingly apertured hub 18 of a small screw-blade fan may be pressed and frictionally held. A double gear 19 is mounted revolubly below the shaft 16, the large member of which is meshed with the gear 17, and the small member of which is in mesh with a large gear 20 revoluble upon a shaft 21, which latter is also mounted revolubly in the frame 14. Fixed upon this shaft and serving to check the gear 20 against sliding movement in that direction, there is a ratchet wheel 22, engaged by a pawl 23 on the gear 20 the pawl being pressed by a spring 24 for proper op eration. On the opposite side of the gear .20 a small gear 25 is fixed upon the shaft 21.

The small gears above mentioned may be of the usual clock type. The gear 25 is engaged by a gear segment 26 mounted between the side pieces of the frame 1 1 closely adjacent the grip 13 against which it strikes at one limit of its movement. The segment is engaged by a spring 27 having a helix engaged around the shaft 28 carrying the segment, one arm of the spring being seated on the frame 14. This spring tends to move the segment to that limit of its movement where it is checked by the grip at 13. In this position it will be seen that the segment projects beyond the frame 1% on one side only.

The handle illustrated happens to be of the plain rectilinear type rectangular in cross section, and tapered from its outer end. The side pieces of the frame 1e are mortised therein and secured by screws or otherwise, whereby the frame is held in proper form to support the gear train and operating segment. The spring 27 tends to move the segment for rotation of the gear 20 in the direction in which the dog will ride the ratchet, and for operating the segment for engagement of the dog and consequent operation of the gear train, an arm 29 is extended from the segment on the side opposite that which is projected from the frame under action close parallelism with the grip 13 when pressed to the inner limit of its movement,

of the spring, this arm being suitably offset from the axis of the segment so as to lie in narrow slot or'channel 29, to receive the narrow part of the arm so that the broad part lies nearly or quite fiush with the grip, an inconspicuous catch 30 being mounted on the grip by which the arm is secured at the inner limit of its movement, which catch may be of any suitable kind; A hand rest 31 is ormed on ne s de of t grip adapted to rest on the hand close to the base of the fore-finger, as shown in Fig, ,5, the

pressure of the thumb being sufficient to retain the grip within the palm, and all the ig may here y e s d or operating he ar 29.- I

The fan blades are curved so as to propel a current of air'away from the handle when 'geaa ot t w dmanipulat n f the a 2 an it is found hat th mentum of the fan and gears is suflicient to cause their continuous movement with a comparatively slow oscillation of the arm 29 producing a strong current of air. Use of the article has also demonstrated that it is no i fi lt er awk to P perly eupport a sunshade and at the same time manipulate the operating arm 29. r he r t 31 may be emi te i esire a h v e epp rt y r p ng th g ip with some of the fingers while others are utilized to operate the arm 29 which need not be pressed entirely against the grip for satisfactory operation ,of the fan. It will be also found practicable to provide a substitute for the rest 31 which will at the same time be an embellishment, by providing a silk cord loop 32 fixed on the outer end of the grip and of a length to allow insertion of the hand therethrough while the handle is grasped, an ornamental tassel being fixed at the outer part of the loop. A casing 33 somewhat pear-shaped and quite small, formed of any suitable material and fixed to the frame 14, completely incloses the mecha'- nism, and adds to the attractiveness of the handle. I i i The manner in which the side pieces of the frame are utilized to form a threaded shank for screwing into a parasol or umbrella Coplei of this patent may be pbtai ned for stem is particularly eifective'and economical.

The sides arebent toward each other imme diately above the small gear 17 and extend ed in parallel relation. These parallel parts are initially made slightly broader than the opening for which they are to be fitted. They may be bent into semicircular form, transversely, at their outer parts so that when put together they form a round shank and when this is threaded it possesses ample streng h for thee te hme t e th hand T e at achm nt of th shank to the e eme a a ol n this-way would. he ufii ieh t hold he f ame n t rm Withe it pe ial fe tenihg u as h t ie e emhedied a ma screw r rivet. has been. ee he eeeer hese pa ts og t so that the han le e m ch ni m may he eta hed from e her el a d used ar a ten el ne, when it ie 7. 1 3 fiie ent as a hair drier e fer et e Se Where treng d aft i desi ed: ta a s f e ers may al o h n ed e ere eht'the I si of t e frame h m bein re s d in altheugh t ese are h b lie ed. eee et j There is illustrated in Fig.- 9 eh da eeon of e dev e-fie era-9m 9 ate hav ng a e e k at ts ent r P ri, the creek eing sre ved e its inner side nd the e er 9-" Whieh i a a e h h re e n th ame ma ne e the l er ?.h e its outer end disposed for oscillation the gro v The g eeve t p het. e t r nd ef h 3 are he e lf n of th v r ay he i Way. iab ty i h l er emh a d in delicate fahr-ics in the garments ,of'the me t ther h 1h 'Phi user is obviated.
