WILLIAM F. COX, OF DAN'VILLE, VIRGINIA.
Application filed November 3, 1919. Serial No. 835,812.
To all whom it may concern.
Be it known that I, WILLIAM F. Cox, a citizen of the United States, residing at Danville, in the county of Pittsylvania and State of Virginia, have invented certain new and useful Improvements in Apparatus for Propelling, Cleaning. Cooling, and Moistening Air: and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled 'in the art to which it appertains to make and use the same.
This invention relates to improvements in apparatus for propelling, cleaning, cooling and moistening air, and it is particularly designed for use with ventilating systems used in large buildings, such as schools, mills and the like. The improved apparatus may also be used for mixing liquids with various gases.
The principal object of this invention is' to provide an improved fan and motor which may be substituted for the fan and motor now used in the ordinary ventilating system.
With the .foregoing object outlined and with other objects in view, which will appear as the description proceeds, the invention consists in the novel features hereinafter described in detail, illustrated in the accompanying drawings and more particularly pointed out in the appended claims.
Referring to the drawings Fig. 1, is a longitudinal sectional view of an ordinary ventilating system, air conduit with my improved liquid motor and fan mounted therein.
Fig. 2, is a fragmentary sectional view of a portion of the motor and fan.
Fig. 3, is a sectional view of one of the fan blades taken on line 3-3 of Fig. 2.
In the drawings 1 represents a ventilat-' ing system air conduit, having an enlarged chamber 2, which houses a fan 3.
Leading into the conduit 1, is a liquid supply pipe 4, which may receive liquid from the city main or from a suitable liquid pump. This supply pipe is extended horizontally as shown at 5 coaxially with the axis of the conduit- 1, and it is supported by suitable bearings 6.
As best shown in Fig. 2,-the pipe 5 is provided with a series of radially extendmg apertures 7, which permit liquid from the pipe to pass outwardly into curved passages 8, provided in a cylinder 9, which is rigid with the pipe 5 and forms a bearing for a rotor 10. This rotor is provided with a series of angular or bent conduits 11, which receive liquid from the passages 8. A pipe 12 has its inner end connected by suitable means such as 13, with each of conduits of the rotor 10,- and the interior of each pipe communicates with one of-the conduits 11, so that liquid may flow from a conduit along the pipe 12 and out through angular'apertures 14. A fan blade frame 15 is provided for each of'the pipes 12, and the outer curvedportion 16 of each frame is apertured as shown at 17, while one of the side portions of each frame is bent into V-shape in cross-section as shown at 18, to permit the fan blade to readily pass through the air. An absorbent cloth cover 19 forms a, casing for each of the pipes 12 and its corresponding frame 15, and this cloth is moistened by means of liquid passing through apertures 14.
In operationliquid passing through the ipes 4 and 5 exits through the aperture into the curved passages 8, which cause a tangential flow of the liquid, and this liquid striking the pockets or corners 20 in the conduits of the rotor causes the rotor to revolve. As the fan blades are rigid with the rotor they will revolve therewith, and
the liquid passing through the apertures 14 will moisten the cloth covers 19. When the covers 19 are thoroughly saturated, centrifugal action will cause the moisture in the covers to move outwardly away from the pipe 5, and this liquid will be thrown against the inner surface of the chamber 2, from which it will be withdrawn by a drain ipe 21, which may either lead thesame bac to the supply or to a suitable waste pipe. If a large amount of liquid accumulates within the chamber 22, formed by the frame and cover of .the fan blade, it may pass outwardly throu h the apertures 17.
From the regoing, it will be seen that I have devised an improved means for propelling, moistening, cooling and cleaning the air which is drawn through the conduit 1 by the fan 3. v
I am aware that various changes and. modifications may be made in the construc tion shown and described without departin from the spirit of the invention as set fort in the following claims.
rations in the What ll claim and desire to secure by Let ters Patent is 1. The combination with a liquid supply cylinder having a series of curved slots for directing liquid tangentially, of a rotor mounted on said cylinder and having angular conduits receiving liquid from the cylinder, outwardly extending pipes receiving liquid from said conduits and having perforations, and fan blades formed-of absorbent material receiving liquid from the perfopipes. 4
2. The combination as set forth-in claim 1 in which a curved frame extends around the liquid supply pipes, and the cloth of the fan blades surround said frame.
3. The combination as defined in claim 1 in which a rigid fan frame is secured to the rotor and is provided with apertures to permit the passage of liquid from the fan blade frame.
asses 4. The combination with an air conduit,
of a liquid supply cylinder mounted therein and having curved-slots for directing liquid tangentially, and a rotor mounted on said cylinder, driven by the liquid from the cylinder and carrying absorbent fan blades which receive liquid from the rotor.
5. The combination with an air conduit, of a liquid supply cylinder mounted therein and having a series of curved slots for directing liquid tangentially, a rotor mounted on the cylinder and having. angular conduits receiving liquid from the cylinder for driving said rotor, outwardly extending pipes having their inner ends connected with said conduits and provided with perforations, fan blade frames secured to said pipes, and absorbent covers inclosing said frames.
In testimony whereof I afiix my signature. I
