Specification of Letters Patent,

Application filed November 16, 1910. Serial No. 592,697.

To all whom it may concern:

Be it known that we, HARRY W. FORBES and FREDERICK LINIGK, citizens of the United States, and residents of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Vapor-Diffusing Devices, of which the following is aspecification.

Our invention relates to dilfusing devices and more specifically to that class thereof especially adapted for employment in the diffusion of disinfectant, aromatic, or refrigeratory fluids. I

The object of our invention is the production of a device of this character especially adapted for employment in conjunction A further object of our invention is the production of a dilfusing device as mentioned which will be of durable and economical construction and eflicient in operation.

Other objects will appear hereinafter.

With these objectsin view our invention consists in a diffusing device characterized as above mentioned and in certain details of construction and arrangements of parts all as will be hereinafter more fully described and particularly pointed out in the appended claims. 1 I

Our invention will be best understood by reference to the accompanying drawings forming a part of this specification and in which,

Figure 1 is a front elevation of a device embodying our invention, Fig. 2 is aside elevation thereof, Fig. 3 is a central section of the device detached from the electric fan or the air current producing means, and Fig. 4 is a transverse section taken on substantially linear-m of Fig. 3.

The preferred form of our construction drawings comprises a conventional electric fan which is shown as consisting of the base 1 and the casing 2 tothe shaft 3 of which is secured the fan or screw 3' the latter being adapted when the armature is properly rotated to producea forwardly directed air current. Surrounding the member 3 is the ordinary frame or. skeleton guard 4.

Arranged forward of the frame 4 is a hollow cylindrical foraminated member or receptacle member 5 to opposite sides of with a which are secured angularly disposed plates 6, the same being evidently adapted, when the fan is in operation, to concentrate a portion of the current produced "by the fan upon the member 5. Provided at the rearward edges of the nally extending bars 7 in which are provided longitudinally extending slots 8. Arranged upon the rearward sides of thebars 7 are straps 9 adjustably secured thereto by means of 'bolts 10 and nuts 11, said bolts slidably engagin the slots 8 in the bars 7. The straps 9 em race adjacent bars of the frame 4 thus serving to rigidly attach the plates 6 and hence the member 5 thereto. By reason of the adjustable connection of said straps to the bars 7 it is evident thatthe same may be adjusted for engagement of fan guard frames of various designs.

Provided within the member 5 is a suitable absorbent filler 5 preferably of cotton or hair. The lower end of saidmember 5 is closed by a cap 12, the upper extremity thereof being closed by a removable cap 13, the latter being provided centrally with an upwardly projecting nipple 14. Arranged axially above the member 5 is a reservoir 15 adapted to contain the fluid to be difi'used. The reservoir 15 is provided with a depending nipple 16 which ple 14 of the cap 13 by means of a transparent or glass tube 17. The upper extremity of the reservoir 15 is provided with a filling opening, the latter being normally closed by an ordinary screw plug 18 said plug being provided with an air vent 18. The passage 19 leading from the lower end of the reservoir 15 is as )will be observed quite restricted, the flow of fluid through said passage being governed by a valve 20 which is rockingly mounted in a sleeve 21 secured preferably by soldering in the ni ple 16, said sleeve being provlded with diametrically the passage 19, said valve being. provided passage 22 which is adapted to register with the perforations in said sleeve in order to permit of the flow of fluid thereby. When said passage 22 is not in alinement 'with the perforations in said sleeve, but

when the same is in the position as shown in Fig. 3, the flow of fluid from the passage 19- will be prevented. Formed upon the sleeve 21 in registration with the perforaplates 6 are longitudiopposed perforations alining with Patented Oct. 24, 1911.

is connected to the niptions at the under side thereof is a nozzle 23 the lateral extremity of which terminates within the tube 17 in such a position that the same will be visible therethrough from without, as clearly shown in Fig. 3. With this arrangement it will be seen that the flow of fluid from the reservoir 15 to the receptacle 5 may be viewed from without, such provision evidently facilitating, adjustment of the valve 20 in the regulation of the feeding of fluid from said reservoir. Longitudinal movement of the valve 20 in the sleeve 21 is prevented in one direction by a collar 24, longitudinal movement of said valve in the opposite. direction being prevented by the upsetting of the opposite extremity of said valve, as clearly shown in Fig. 4e. 7 Said valve is provided with a laterally projecting elongated stem 25 upon which is carried a wing or blade 26 the latter being preferably formed of aluminum in order to reduce the weight thereof. The arrangement is such that said wing will be so disposed that upon operation of the fan the current produced thereby will impinge against the same to effect the rotation of the stem '25 and hence the valve 20 in order toeffect the opening of the latter. Formed integral with the sleeve 21 is a bracket or arm 27 carrying at its outer extremity a U-shapedmember 28 the parallel arms of which are disposed at opposite sides of one of the edges of the wing 26. Threaded in said member 28 are screws 29 and 30 which are adapted to abut against the opposite sides of the wing 26 in order to limit the extent of movement thereof! With this arrangement it will be seen that by simply adjusting the screw 30 adjustment may be made whereby the valve 20 will permit of full or only partial flow of fluid thereby. A torsional spring 31 having its respective extremities secured to the stem 25 and to the bracket 27 is arranged to normally hold the valve 20 in closed position, said valve there fore being open; that is fluid is fed from the reservoir 15 only when the ,fan is in opera-- tion since in such operation .the impingement of the current against the wing 26 rocks the same to 'a positionagainst the screw 30 and hence the valve to open position. i x

In the operation of the device, the screw 30 being adjusted so as to permit of any flow of fluid desired when the wing 26 is rocked, upon operation of the fan the fluid contained in the reservoir 15 will drain therefrom and be deposited into the receptacle 5. Here said fluid will'be vaporized in the filler 5 whence it will be carried by the current of air passing through the member 5 and diflused into the atmosphere.

In a device of a construction as set forth it is apparent that the diflusion of any fluid roovyoa e or liquid such as a disinfectant, aromatic, etc., may be readily and effectually diffused. The device is comparatively small and hence does not to a great extent impede the current of air produced by the fan. The same is entirely automatic in its operation inasmuch as the same operates, that is liquid is fed from the reservoir to the member 5 only when the fan is in operation, such feeding being discontinued immediately upon cessation of operation of the fan. The device is of simple and economical construction hence may be manufactured at a low cost, and the same is not susceptible to readily becoming inoperative.

While we have illustrated and described the preferred form of construction for carrying our invention into effect this may be varied somewhat without departing from the spirit of the invention, we, hence do not wish to be limited to the precise details of construction as set forth but desire to avail ourselves of such variations and modifications as come within the scope of the appended claims.
