In Argentina November 11, 1948 2 Claims. "(01. 23o- 268) This invention relates to fans and more par- I:ticularlytothat type of fans generally known as parts. f

@folding fans having accordion webs. f

.The principal objectof my invention is to pro- -.vide:.folding fans which when folded the webs areentirely concealed Within the handles and as i .examples thereof I have illustrated in the accompanying drawings two highly satisfactory formsf y Athereof of varying design but both incorporating the primary features of my invention.

-Another object of my invention is to provide :such fans which include simple and inexpensive ...operatingparts of highly eicient and practical-:i

if; construction, and pleasing in appearance.

,-.- .Another object of my invention is to provide such a Vfan which when extended the web will f `have a, substantial spread with a large area posi-y Fig. 15 is a plan view of the web and associated Fig.= 16 is an enlarged fragmentary vertical sectional view of the fan handle. f

In general this inventionrelatesto a fauconsisung of a houow handle zu `into vwhich fomingjwebs'rZI can be drawn and completely enclosed orconcealed as best' shown in Figs.3 and "4 and when pushed out a spring '22Will operate tol spread lthe lfan web fromy its'folded condition tol its expanded position ready` for use as shown by the examples Figs. -1 and'1g4. There are, of course, many shapes and designs of fans made of various'materi-als',v with stronger and weaker frames,r with blades of ypaper for starched tissue or with light tissue fitted out with ribs. Also the handle and its upper part which tively but yieldably held in spread or open posi- .sa

tion `and when closed the webs will be entirely Aconcealed in a comparatively short handle having a length only slightly in excess of the length ...of the radial folding web portions.

Still further objects, details and advantages ofi-r .my invention will appear inthe following specication supplemented by the accompanying draw- .ings vforming a p-art thereof and illustrating highly :satisfactory embodiments thereof.

In vthe drawings:

forms the fan center can have various appearances.' Ask examples are presented two fundamentally equal types but of different external shapes. I H

Referring particularly to the fan design illustrated in' Figs. 1 vto 13 inclusive it'will be seen that onofhouow hanoue 2u for the major part' of its length is in general of rectangular cross sec- Ytion 'and 'each of its two side faces 23 has -a mid- Wayf long'itudinal channel or slot 24 the length of Y Fig. 1 is a front elevation View with parts.`

' design which covers a limited area of the fan web which determines distance the fan web can vbe drawn into the handle. Each ofthe two side face's' has an enlarged lextension 25 of'fanciful 2 Ir and its associated parts; in this handle the end Fig. 5 is a detail plan view of the web and associated parts.

Fig. 13 is a plan View of the spring retaining member shown in Figs. '11'v and 12. 1 AAFigjli is a front elevation view of a slightly modified form of fan in accordance with my inventlon;

.portions 26 are flared outwardly at their upper ends 2l and connect the lower portions of extensions 25t'hereby providing abutments for the associated fan' web parts as `will hereinafter be described. The lower closed end ofhandle ZUis shownprovided with la. strap or` eyelet 2'8 through which a carrying cord, ribbon or the like may be secured. Y The fan webs 2l as shown in detached'elevation and plan respectively in Figs. 5 and 6 comprise folding connected web sections or blades 2 3, the outer sides of the outermost of which' are secured to substantially rigid-bars 3|).A Bars 3 0 each terminates at its lower yend with a pair of centrally apertured symmetrical side plates 3 I and na transverse hook element 32 as shown in Figs.

7 and 8, respectively for the reception of a corinecting ..and operating pivot member V33 which holds the bars in symmetrical alignment and also retains the spring 22. As shown in Figs. 11 and 12 .pivot member 33 passes through the apertures inthe four side vplates 3l as well as spring 22. Spring 22 is thus housedbetween the overlapping, pairs'. offside plates 3|l of the bar elements 30 `and hasends 34 which engage the hook element 32 of one of pivot with operating heads 42. projections 43 are'round as distinguished from the shape of projections 25. The fan web 44` as means for moving the fan webs 2| into and out of handle 20, the movement'b'eing determined by the length of channels 24. As shown in Figs. 1 and 2 the heads 31 are at the upper extremity of the channels 24, practically at the vertex of the yarious.websec tions orY blades 29 convergence.

By moving these pivot heads 31 downward to the otherend of channels 24 spring 22 yields to the folding lof the fan webs l2| and the latter is drawn d own into the hollow handle 20 in an entirely concealed position, unless the fan web sectionsfor blades 29 are designed and constructed to beefa greater length so as to afford a larger .fanspread area, in which case the upperend of I the fan-webs may protrude above the enlarged extensions 25. of the fan-is effected by merely moving the heads 31.1of pivot .member 33 from one extremity of channels 24 tothe other extremity which requires very .li ttle effort and -spring 22 operates to effect the :opening of the webs and readily yields to ,its closing.

Thus the opening and closing .As aguide means for the fan web side bars '30. and to facilitate opening of the fan webs 2| with a weaker spring member 22r than would otherwise be required, the hollow handle has longitudinal internal channels 38 along the side edges of thefaces 23 and corresponding extensions 25 -along the ljuncture with the connecting sideedge lportions 26 of handle 20 and the outwardly curved upper extensions 21 thereof. Bars -.30, adjacent totheir lower ends on each Iside,

haveprojections 39 which cooperatively engage these grooves or channels 38. It will be seen by their yopen position for spreading the" fan web 2| as shown in Fig. v 1, and conversely when the 'bars are drawn down the channels operate on -these projections 39 to swing the bars 30 to closed position folding the fan web sections or blades 29 upon each other so that the fan webs can be drawn into handle 20. Referring to Figs. 14, and 16, the fan illustrated is substantially the same Yexcept for design vfeatures and a few changes in details.

It includes an internally grooved hollow handle 40 having channels.4| for fan side plate connecting The upper face shown in plan in Fig. 15 has an upper conforma- .tion rounded instead of straight as shown in Fig. 5. Fan webs 44 have end bars 45 each with "a pair of cooperating apertured hinge `plates 46 for engagement on the pivot member and hook and spring elements may be employed though not essentially as' projections 41 on bars 45 cooperatingwith grooves 4| operate to swing the bars outwardly when they reach the upper outwardly extending portions 48 of grooves 4| as shown in Fig. 16. It will be seen that in this arrangement the bars 45 are swung through a 90 angle so that the fan web 44 occupies a spread of 180 as compared withI thelesser spread of Having described the principles of my invention as applied to two highly practical forms 0f fans in accordance with my invention it is to be understood that my invention is not limited to the exact vdetails of construction, the inventionbeing-defined in the following claims.
