VENTILATING ATTACHMENT POR S'IOVES.v

To ALL WHOM 1T MAY coNcERN:

Be tknown that I, THOMAS S'. BpWMAN, of St. Louis, in the county of St. Louis, and State of Missouri, have invented a new and useful improvement in Moist Warm-Air Ventilator; and I do hereby declare that the following is a full,clear, anld exact description thereof, which-will enable others skilled in the art to :make and use the same, reference being had to the accompanying drawings, forming part of this specification.

rilhis invention consists in a device for supplying pure and moist air to rooms in dwelling-houses, by surrounding the stove pipe wthan air-drum, the bot-tom of which is connected with a. base which contains water which is evaporated and discharged into the room with fresh air, as will be hereinafter described.

` Figure 1 represents a central vertical section of the `ventilator through the line :z: :z: of fig. 2i.

Figure 2 is a. sectional view from the line y y of iig. `1.

Similar letters of reference, indicate like parts.

A portion of the stove is shown in redand the base of the ventilator is represented as standing upon the stove enclosing-the stove-pipe hole., 1 e i A is the stove pipe. B is the base of the ventilator, which contuins water. The stove pipe sets over a angeion the top of the base, as seen in the drawing. C represents the ventilator. `D is afresh-air supply pipe, which is passed into the open air in any convenient manner. It has a damper, d. to shut-off lthe air'when desired. The casing c extends upward to any 'desired height, where a cap, d, may close the top around thestove pipe, as represented in the drawing, with holes a below for the discharge of the air into the room. f is a spout for supplying the base B with water. l

Theoperation is readily understood from the drawing. The vapor from the water mixes with the current V of air which passes up through the ventilator from the pipe 1) and both are discharged into the'room through the apertures a, thus furnishing an atmosphere both pure and moist and suitable for respiration. v-

What I claim as new, and desire to secure by Letters Patent, is-

The base B and the drum C, arranged and operating as herein shown and described, in combination with a.

stove and stove pipe, substantially as'aud forlthe purposes set forth.
