AIR-DIFFUSER.
SPECIFICATION forming part Of Letters Patent NO. 701,228, dated. May 27, 1902.
Application filed November, 1901. Serial No. 83,607. iNo model.)
clear, and exact description of theinvention,
such as will enable others skilled in the art to which it appertains to make and use the same. 1
My invention relates to improvements in air-diusers; and the object of the invention is to deflect or spread a current of air directed thereagainst, so as to cause diffusion of the air in all directions. i
I-Ieretofore a current of air induced by an ordinaryV rotary fan scarcely spreads beyond the circumferential limitsof the fan. Such a blast or jet of air coniined to a direct or limited path is too strong for comfort and does not tend to cool the atmosphere of a room. draft of such force are liable to be very ignjurious.
Previously devices have been provided for partly diffusing a current of air; but never has the diusion been wholly accomplished.
' My device is intended to overcome the objections to the use of a rotary fan giving a direct blast and to provide for the thorough diffusion of all the air within a room.
Broadly, my invention consists of a series of deflecting-blades arranged one within the other of such construction that they will be capable of spreading a current of air in all directions. Said blades are suitably held in their respective arrangement, andmeans may be provided for attaching the device to the guard of an ordinary electric fan.
In the accompanying drawings, illustrating the preferred embodiment of my invention, Figure 1 is an elevation of my device applied to the guard of an ordinary electric fan. Fig. 2 is a cross-section thereof.
In carrying out my invention I provide a series of deiiecti-ng-blades l, arranged one within another. Preferably these blades are circular and arranged concentrically within each other. Cross-pieces 2 are suitably connected to the blades, preferably by soldering, for holding them in .their respective places. In the drawings are shown two cross pieces The effects resulting from being in aV or wires placed at substantially right angles to eachother upon opposite edges of the blades, and for attaching the devices to the guard of an ordinary electricfan I provide hooks 3 3 3 3, preferably connected to the outer blades'at diametrically opposite points. These hooks are preferably constructed of spring metalin substantially the form shown, and forconvenience in connecting the hooks to a guard those diametrically opposite are faced in the same direction.
By using my device a 'current of air contacting therewith will be spread lin all directions. y Thiswill cause diffusion of all the air in a room and obviate the necessity of a person being out of the direction of the fan for fear of injurious effects. Moreover, the air in the room will be cooled wherever the diffusion has taken place and not along a defined path, as in the case of the ordinary rotary fan.`
It will be observed that a device constructed according to my invention will occupy but a limited space, will be durable, and cheap Vof manufacture.
Vplaced-upon the `delivery sideof afan, a se ries of deflecting-blades arranged concentrically one within another, and 'means for connecting said blades.
2.- In an article of the character described, placed upon the delivery side of a fan, a series of deflecting-blades arranged concentrically one Within another and slanting out.- wardly, and means for connecting said blades.
In testimony whereof I affix my signature in presence of two Witnesses.
