ELECTRIC-FAN AIR-SPREADER.

No. 9l5,178. v Specification of Letters Patent.

Application filed July 27, 1908. Serial No. 445,599

To all whom it may concern: I

Be it known that I, NEWTON S. HILLYARD, a citizen of the United States, residing at St. Joseph, in the county of Buchanan and State of Missouri, have invented certain new and useful Improvements in Electric-Fan Air-Spreaders, of which the following is a specification.

The object of my invention is to provide a device for attaching at the front of electric fans that will prevent the air being driven with so great force practically from the center out, only; that willspread and equalize this volume into the surrounding space as well as in the space forward of the fans, thus securing a better distribution of the air.

I accomplish my object by the mechanism illustrated in the accompanying 'drawings, in .which,

Figure l is a perspective of the device attached to the frame of an electric fan; Fig. 2 is a sectional elevation showing the manner of securing the device to the frame work-of a ing perforations h h fan; Fig. 3 is a sectionalelevation showing the manner of securing the device to a modi-v fied construction of the frame of the fan and Fig. 4 is arear elevation of Fig. 3.

Similar letters refer to similar parts in the several views.

In the drawings A is a case adapted to inplose an electric motor-and B a supportthere- C- is a revoluble fan and D a protecting frame for said fan with a hub member'E.

H is a conical shapedair s reader havwhic break the force of the breeze upon the persons or articles in line therewith, such as loose pa e'rs upon a desk which are often disarrange by the strength of the cjirrent of air. Said spreader consists of a single circular piece stamped from a metal sheet and bent into the shape mentioned. The body of the spreader consists of 'a plurality of furrows I I narrow at the, apex or small end H of the spreader and widening to the lar e open end, asshown in Figs. 1 and 2. These urrows are adapted to receive and carry air in partially separated currents, those which do not 7pass forward passing out through perforations h The air from the fans is thus distributed practically inall directionsfinl an apartment or ofiice, reaching the individualin roximity' to the fans as well as others with a mild and refreshin force. Said small fitted snugly within said hub member E and retained therein, as shown in Figs. 1 and2, by a metal pin J inserted through perforations it 72. just back of and in contact with said hub member. The apex of said spreader being pressed flat and'also provided with erforations h h is adapted not only to rames with a hub member, as shown in Figs. 1 and 2, but also to frames in which the hub member is omitted and the frame wires extend to a common center, as shown in Fig. 3. When attached to the latter class of frames pins K K of the shape shown in Fig. 3 are wire, the ends inserted through two of the erforations and twisted or KIlOttGd, thus holding the flattened end of thespreader rigidly a ainst the converging wires of the frame. owever, I do not wish to confine myself to either form 'of pin, but reserve the privilege to use any suitable means that is merely mechanical for attaching the device to any form of electric fan frame.

What I claim'and desire to secure by Let ters Patent, is I 1; The combination with an electric fan and the frame thereof, of an air spreader its apex held in rigid engagement with the cen tral part of the front of the frame, said apex being flattened and perforated, the body of Patented March 16, 1909.

preferably used, each engaging with a frame said spreader consisting of ridges slightly I being closely perforated and diverging a part the perforations dividing and reducing the force of the 'air passing forward of the fan through said perforations, substantially as set forth-and shown. c

2. An electric fan airspreader comprising a single piece of metal closely perforated bent into cone sha e its apex flattened to adapt it to be fastened by means of pins to the front v of a fan frame, the outside thereof having diverging sharplybent ridges with. smooth 'corres ,ondin'g incurves between said ridges widemngfrom the apex to the outer circumference of the spreader, the outer surface of said ridges and incurves deflecting the air horizontally, vertically, and in all intermediate directions while the erforations and the interior surface of said ridges and incurves disperse or apexend of the sprea or is adapted to be substantially as shown and\described.

said-circumference, said ridges and incurves the air gently to all-pointsforward thereof,

spaced at the apex and diverging to the ClI of the air away from'the front of the fan and adapting it to be attached tothe central part of t e front of the fan frame, ridges on the outer surface of the spreader diveiging'from said apex to the circumference an incurves forming valleys between said ridges narrow at their apex ends and widening thence to the 10 I circumference,. substantially as shown and setforth. j

' In testimony whereof I aifix mysignature in presence of two witnesses.
