AIR-FEEDING ATTACHMENT FOR COAL-RANGES AND THE LIKE.

Application filed June 30, 1915.

To all whom it may concern:

Be it known that I, RICHARD LACOURSE, a citizen of the United States, residing at Anaconda, in the county of Deerlodge and State of Montana, have invented a new and useful Air-Feeding Attachment for CoaLRanges and the like, of which the following is a specification.

This invention relates to an air feeding attachment for coal ranges and the like, one of the objects of the invention being to provide an attachment having means whereby air can be directed therefrom into a stove at points either above or below the fuel, the air being admitted to the attachment through a flue extending preferably to a point outside of the structure in which the stove is located, a novel arrangement of dampers being provided whereby the flow of air therethrough can be controlled at all times.

A further object is to provide an attachment which is simple in construction and which will not occupy an objectionable amount of space when positioned upon the stove.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the in vention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the inventlon.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings :Figure 1 is a vertical transverse section through a portion of a stove and through the attachment in position thereon. Fig. 2 is a section on line A-B Fig. 1. Fig. 3 is a section on line CD Fig. 2.

Referring to the figures by characters of -reference 1 designates a box-like structure closed at one end while opening into the other end thereof is a flue 2 which may be extended through the wall W of the room or other structure in which the device is to be used, whereby fresh air may be supplied to the attachment. The casing 1 has a longitudinal series of outlet ports 3 in one side wall thereof and extending from said wall are connecting flanges 4:. Guide cleats 5 are formed on or secured to said side wall of Specification of Letters Patent.

the casing 1 and are slidably engaged by a damper 6 having openings 7 adapted to be moved into or out of register with the ports 3 thus to .open or close said ports. The damper 6 has an arm 8 at one end whereby it can be shifted longitudinally.

Formed in the top of the casing 1 is a longitudinal series of ports 9 and guide cleats 10 are formed on or secured to the top of the casing adjacent this series of ports and are slidably engaged by a damper 11 having openings 12 adapted to move into or out of register with the ports 9. Damper 11 has an arm 13 by means of which it can be readily shifted longitudinally so as to open or close the ports.

Retaining cleats 14 are formed on or secured to the top of the casing 1 and are de tachably engaged by flanges 15 formed along the sides of a hood 16 which extends up wardly from the casing and overhangs the damper 11. The longitudinal walls of this hood converge upwardly and merge into the top and bottom respectively of an outlet flue 17. Although the hood has been shown as made in a separate piece from the casing 1, it is to be understood that if preferred it can be formed integral therewith. This modified construction is so obvious that it is not deemed necessary to illustrate it.

A damper 18 is arranged within the flue 2 and by means thereof the passage of air through the flue to the casing 1 can be con trolled.

In Fig. 1 a portion of a range has been illustrated at R, this range having a grate An opening R is formed in the wall of the range below the grate G and an extension E projects from the range above the grate G. This extension is adapted to receive the flue 17 while the opening R is adapted to receive the flanges 4, these flanges being bent back against the inner face of the wall of the range as shown, thus to fasten the attachment securely in place.

When starting a fire, the damper 11 is moved to closed position, while the damper 6 is moved to open position. Thus when the damper 18 is opened, fresh air will pass through the flue 2 into the casing 1 and thence through the ports 3 to the interior of the stove below the grate G. After the fire has been well started, damper 6 can be closed,

Oopies of this patent may be obtained for so ,as to allow the fresh air to enter the upper portion of the stove through the flue '1 and eXtension'E, this being true especially when the damper 6 is open, the fresh air supplied to the top of thestove mixing with the unconsumed products of combustion within the fire pot and causing them to be consumed. By closing the damper 6 and opening the damper 11, the burning of fuel in the stove can be checked materially inasmuch as the draft will thus be shunted around the grate. I

What is claimed is The combination with a stove casing having an opening-in one wall thereof below the grate and an air inlet extension extending from said wall above the grate, ofa boxlike casing having one side fitted Within the opening below the grate, retaining flanges extending from said casing and engaging the inner face of the wall, there being ports within the inner sides and within the top of the casing, a hood extending longitudinally vof the top of the casing and having a laterally projeoting outlet extension detachably seated within the extension on the Wall of the stove, said top ports opening into the hood, dampers'slidably mounted upon the top and inner wall of the casing for regulating the fiow of air through the ports, an air five cents each, by addressing the Commissioner 01' Patents, Washington, D. O.
