HEATING AND VENTILATING- SYSTEM.
Specification of Letters Patent.
Patented May 11,1915.
Application filed February 23, 1911. Serial No. 610,214.
To all whom it may concern:
Be it known that I, LEO C. SMITH, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Heating and Ventilating Systems; 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.
My invention relates to heating and ventilating systems wherein a stove or heater is placed within a surrounding jacket through which the air of the room is circulated.-
The invention is directed particularly to the provision of improved means for drawing the foul air from the room, to a greater or less extent, as desired, and, to such ends, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claim.
In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.
Referring to the drawings, Figure 1 is a view partly in vertical section and partly in side elevation, illustrating my invention applied to a heater of the general character above indicated; and Fig. 2 is a detail view in rear elevation, showing the foul air pipe and the damper provided therein.
The heater 1, which may be of any suitable construction, is placed within a surrounding jacket 2, which may also be of any suitable constructionbut which is arranged so that the air of the room may be circulated Hence, as shown, the said jacket 2 is open both at itsupper and lower ends and its lower endis spaced above the floor. The smoke pipe from the heater 1 is indicated by the numeral 3.
-The foul air pipe 4 is extended vertically through the jacket 2 and one wall thereof is either formed as part of or directly secured to the outer surface of the heater 1, so that a large amount of heat will be conducted into thewalls of the said foulair pipe and radiated therefrom, thus producing a strong draft in the said foul air pipe. The lower end of the foul air pipe 4 should be extended considerably below the lower end of the jacket 2, so that it will pick up the relatively heavy foul air at a point close to the floor. The upper end of the foul air'pipe 4 maybe extendedto any suitable point of discharge, either through the roof or otherwise, to the exterior of the building, but should be inclependent of the smoke pipe 3 and of the chimney or flue into which the said smoke pipe is connected. At a point preferably just above the upper edge of the jacket 2, the foul air pipe 4 is shown as provided with a rectangular damper box or compartment 5 provided, as shown, at itsrear with a discharge passage 6 having, preferably, the same cross section or conducting capacity as the body of the foul air pipe.
Located within the compartment 5 and hinged thereto at its upper edge, by a small shaft 7, is a damper 8. This damper 8, when moved into a vertical position indicated by dotted lines in Fig. 1, will entirely close the discharge passage 6, so that all of the foul air passed upward through the pipe 4 will be discharg'edfrom the room. When this damper 8 is set in the intermediate po sition shown by full lines in Fig. 1, part of the foul air willpass back into the room through the passage 6, while part thereof will pass upward through the foul air pipe 4 and will be discharged from the room. When the valve 8 is turned upward into a horizontal position, it will close the upper portion of the foul air pipe 4 and will cause all of the air circulated in the pipe 4 to pass back into the room. This arrangement of the damper is highly important and is thought to be novel. It provides for a large range of variation in the amount of foul air that will be drawn from the room and, at the air therethrough and the radiation of heat. f As already indicated, the air circulatedthrough the foul air pipe 4 may be partly or wholly returned to the room. Hence, when the device is not used for drawing foul air from the room, it may be used as an auxiliary device, acting in conjunction with the jacket 2, to circulate the air of the room. If the provision for circulating the air of the room through the foul air pipe was not made, it is evident that whenever the damper was moved to prevent the discharge of foul air, the foul air pipe would become a dead air space and its total cross section would be deducted from the air spacecon-' loo tained between the heater and jacket. As shown, the damper 8 is adapted to be adjusted by an arm 9 secured to one end of the shaft 7, and having frictional engagement with the side of the damper box 5. In my improved device above described, that portion of the foul air pipe 4, which is below the damper S, is always in full action, either to discharge all of the'air circulated therethrough out of the room, or to discharge all of the air circulated therethrough back into the room, or to discharge part of the air out of the room and part of the air back into the room. Furthermore, the circulation of air through the said foul air pipe does not in any way affect the draft of the stove or heater.
