To all whom, t may concern:

Beit known that I, CHARLES C. ROTH, a citizen of the United States, residing in the city and county of Denver and State of Colorado, have invented certain new and useful Improvements in a Combined Smoke-Elue and Ventilating Device; and I do 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, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to a combined smokeflue and Ventilating device, more especially adapted for use in tents or tent-cottages, but which may be advantageously employed'in other structures.

The invention consists of a damper-controlled flue adapted to be mounted in the top of the structure and surrounded by a ventilating-flue which communicates at the top with the outer air and at the bottom with openings adapted to be controlled by a rotary slide. ln the construction shown in the drawings the device is applied to a tent or tent-cottage and the Ventilating-Hue is provided with openings which communicate with the space between the roof proper and the fly.

Having briefly outlined my improved construction, as well as the function it is intended to perform, I. will proceed to describe the same in detail, reference being made to the accompanying drawings, in which is illustrated an embodiment thereof.

In the drawings, Figure 1 is a fragmentary section taken through a structure equipped with my improved device. Fig. 2 is an underneath view of the device looking in the direction indicated by arrow 2 in Fig. l.

The same reference characters indicate the same parts in both the views. v

Let the numeral 5 designate a frame surrounding an opening in the top of the roof 6 of a tent or other structure. Above this frame 6 is a frame 7, surrounding an opening in the top of the fly 8 above the roof proper of the structure. Inserted in and secured to the frames '5 and 7 is the Ventilating device 9, preferably composed of metal and having its top provided with a covering 10, which is connected with the upper extremity of the ventilating device 9 by metal straps 12. .The

top 10 is supported to leave a Ventilatingspace between it and the upper extremity of the part 9 for the escape of the air from the inside of the structure. In the bottom 9a of the device 9 are formed a number of openings 13, controlled by a rotary slide 14, provided with a manipulating projection 15. The slide 14 is provided with openings 16, adapted to register with the openings 13 when the slide 14 is adjusted, to give the greatest possible ventilation. The ventilation, however, may be controlled at will, whereby the openings 13 may be left only partly exposed, or they may be entirely cut oli', if desired.

Between the two frame parts 5 and 7 and communicating with the space 17 between the roof and the fly-openings 18 are formed on the device 9 for the escape of the air between the roof and the fly, thus preventing the ac'- cumulation of heated air within the said space. This is an important feature in structu res with which this device will be used.

The rotary slide 14 is held in place by small clips 19, which overlap its exterior edge, while its interior edge is engaged by a flange 20, formed around a central opening formed in the bottom 9a of the device 9. As shown in the drawings, this bottom 9 is rectangular in shape and secured to the rectangular frame 5 by fastening devices 21.

Inserted in the opening in the bottom 9a of the Ventilating device 9 is a smoke-iue 22, which fits tightly in the said bottom and extends upwardly nearly to the top of the ventilating device. Above the bottom of thelastnamed device there is a considerable space between the Ventilating-flue and the smokeue. The upper part of the smoke-fine is provided with bow-shaped springs 23, which engage the inner surface of the Ventilating device and properly center the smoke-fine therein and at the same time lock the latter in position by reason of the frictional engagement between the Ventilating device and the said springs. The smoke-flue projects below the bottom of the Ventilating device, and its lower extremity may be provided with a detachable thimble 24, provided with a mesh covering 25, to prevent insects from entering the structure through the said flue. Above the thimble Q4 is a slide 26, forming adamper which may be completely closed, if desired, when a stove is not employed. Vhen a stove is used within the structure, the stove pipe or flue 27 may be inserted in the lower extremity of the Hue 22. In this event the thimble 24 is Hrst rcmoved. This thimble is only employed when the smoke-Hue is not used in connection with a stove. The damper 26 may be left open, if desired, even when a stove is not employed, since it increases the Ventilating capacity of the device.

From the foregoing description the use and operation of my improved device will be readily understood. l

Having thus described my invention, what I claim isl. In a structure having a roof and Hy, a combined smoke-Hue and Ventilating device, consisting of a smoke-Hue and a surrounding Ventilating-Hue, both Hues being open-ended and forming independent passages between the atmosphere and the interior of the structure, andeach Hue being provided with suitable means for controlling said passage, the Ventilating-Hue also communicating with the space between the roof and Hy.

2. The combination with a structure provided with a roof and Hy, of a Ventilating-Hue mounted therein and passing through the roof and Hy, the said Hue communicating with the .atmosphere at the top, the interior of the Vtilating-Hue, a suitable space being left between the two Hues, substantially as described.

3. The combination of a structure having a roof and Hy respectively, provided with central openings, frames surrounding said openings, a Ventilating-Hue passing through the said openings and fastened to the frames, the Hue having communication with the atmosphere at the top and with the interior of the structure at the bottom, and with the space between the roof and Hy intermediate its extremities, a cut-off slide fory controlling the bottom opening, and an open-ended Hue centrally located in the Ventilating-Hue for the purpose set forth.

4. The combination with a structure having a roof and Hy of a Hue open at the top and bottom, a slide for controlling the bottom opening, the said Hue communicating with the atmosphere at the top, the inside of the structure at the bottom and the space between the roof and Hy intermediate its extremities another Hue centrally located in the Ventilating- Hue, guides interposed between the two Hues at the top for centering the central Hue which is fitted tightly into the bottom of the ventilating-Hue, the central Hue being open-ended and having a mesh-covered thimble inserted in its lower extremity.

In testimony whereof I aHiX my signature in presence of two witnesses.

CHARLES c. ROTH.
