HUMIDIFIER.

Specification of Letters Patent.

Patented Nov. 9, 1909.

Application'filed December 16,: 1907. Serial No. 406,607.

To all whom it may concern:

of Providence, county of Providence, and State of Rhode Island, have invented certain new and useful Improvements in Humidifiers; and I do herebydeclare the fol lowing specification, taken in connection with the accompanying i drawings, forming .a part of the same, to be a full,' 'clear, and

exact description thereof.

The invention relates to humidifiers or air-moistening machines and has for its object to produce a machineof this character which is simple in construction and efiicient in operation, and one that will. produce a large amount of moisture in asuitable form to be quickly absorbed by the air passing through said machine.

To this end the invention consists of the novel construction and arrangement of elements comprising my improved-form of humidifier, hereinafter described and claimed, reference being had to the accompanying drawings.

Referring to the drawings, Figure 1 is a longitudinal sectional view of my improved humidifier in its preferred form. Fig. 2 is a front end view. Fig. 3 is a rear end view. Fig. 4 is a transverse sectional view.

As shown in the drawings, the machine comprises a cylindrical casing 1 open at both its forward end 2 andits rear end 3, for the passage of air through said casing. At the forward end 2 of thecasing l is a spider 4 provided at itscenter with a bear-' ing 5, and at the rear end 3 is a'sifnilar spider 6 and bearing 7. Mounted in the bearings 5 and 7 is a shaft 8, having a circular fan 9, an elongated circular brush 10 and a driving pulley 11 secured thereto. The blades of the fan 9 are so shaped and arranged as to maintain a steady current of air through the interior of the casing 1 when said fan is rotated in the right di: rection. The brush 10 is arranged toextend substantially the entire length of the casing 1 for a purpose to be hereinafter described. The shaft'S may be driven'in any well-known manner, the driving means shown comprising an electric motor 12, pulley 13 and belt 14.

Extending through the casing 1 at right angles to the shaft 8 is a water supply pipe 15 having av U-shaped fitting 16 at its free end in which is screwed three perforated branch pipes 17 extending parallel with and in close proximity to the brush 10, as shown in Figs. 1 and 4. The Water supply pipe 15 is also provided with another perforated branchpipe 18 near the inner wall of the casing 1. I

, Within the casing 1 is a supplemental casing comprising two rims l9 and 20 secured together by rods 21 and held in position by meansof the clamping bolts 22 and nuts 23. Secured upon the

rings

19 and 20 and extending between the same is a cylindrical bag or casing 24 preferably made of fabric. Said bag 24 is open at each end and surrounds the brush 10, all as shown in Fig. 1. The casing 1 is provided with suitable legs or standards 25 for securing the same to the ceiling-26. 7

The operation of the device is as follows: The water in the supply pipe 15 is supplied in small quantities through the perforated branch pipes 17 onto the brush 10. Said brush 10 is caused to revolve at a very high rate of speed and throws the drops of water against the inner wall of the bag 24, thereby breaking the drops and creating a heavy mist which is absorbed by the current of air drawn through the bag 24 by means of the fan 9. The water supplied from the perforated branch pipe 1' falls upon the outer wall of the bag 24 and is absorbed by the current of air passing through the casing 1 around the exterior of said bag 24. Should the supply of water through the perforated branch pipe 18 falling upon the exterior of the bag 24 be greater than can be absorbed by the current of air upon the exterior of said bag 24, the surplus water will be absorbed by and pass through to the interior of said bag where it will be operated upon by the brush 10, or said surplus water will fall to the bottom of the casing 1 and out through the overflow pipe 27. A drain pipe 28 is also provided in the bottom of the casing 1 for draining all the water out of the casing. It will thus be seen that the amount of moisture contained within the casing 1 may be very great, if desired, and, as the brush 10 extends substantially the entire length of said casing, said moisture will be worked into a suitable spray or mist throughout the entire length of the casing. If h0w= ever a less amount of moisture is desired, the Water supply may be reduced by omitting the perforated branch pipe 18, or one or more of the branches 17 as desired.

l Vhat I claim as my invention and desire to secure by Letters Patent is:

1. An article of the class described comprising a suitable casing, a shaft mounted to revolve in said casing a brush mounted on said shaft and extending substantially the entire length of said casing, a perforated Water supply pipe in close proximity and extending parallel to said brush, and means for drawing a current of air through said casing upon all sides of the brush.

2. Anarticle of the class described comprising an outer casing, a supplemental casing secured within said outer casing, a brush mounted to revolve within said supplemental casing and extending substantially the entire length thereof, means for supplying moisture to the inside and outside of said supplemental casing, and means for drawing a current of air through said outer casing and upon both the interior and exterior of said supplemental casing.

3. An article of the class described comprising a suitable casing open at each end, a shaft mounted in said casing, a fan, an elongated brush and a driving pulley secured to said shaft, a fabric-bag open at each end and secured within said casing, and a perforated water supply pipe upon the in= terior and exterior of said ag.

4. An article of the class described comprising a suitable casing open at each end, a shaft mounted in said casing and having a fan, an elongated brush and a driving pulley secured thereon, two rings secured within said casing, a fabric-bag open at each end mounted on said rings, a water supply pipe extending through the side of said casing and bag, a series of perforated branch pipes extending from the end of said water supply pipe in close proximity and parallel to the elongated brush, and a perforated branch pipe arranged between the fabric-bag and easing.

5. An article of the character described comprising a suitable easing, a brush mounts ed to revolve in said casing and extending substantially the entire length thereof, a water-supply pipe extending through said casing at right angles to said brush and provided at its free end with a U-shaped fitting, a series of perforated branch pipes secured in said U-shaped fitting and extending in close proximity and parallel to said brush, and a fan mounted to revolve adjacent one end of said brush.
