. STOVE AND FURNACE ATTACHMENT Filed March 10, 1939 2 Sheets-Sheet 2 INVENTOR ATTORNEYS Patented Sept. 17, 1940 UNITED STATES PATENT OFFICE 1 Claim.
The invention relates to a stove and furnace attachment and more particularly to a smoke consuming device.
An object of the invention is to provide an at- 4tachment of this character wherein the'air inlet mouth thereof is susceptible of separable mounting upon a re door of a furnace, boiler, stove or lthe like and is of a size conforming to such door, being adjustable for the proper fitting thereof according to the size of the door to which it is to Ibe applied and includes a plurality of sections, these being interfitted with each other and separably fastened together in a novel manner while the air inlet mouth directs air to the interior of the furnace, boiler, stove or the like for proper admission to the fuel bed within the same. I
A still further object of the invention is to provide an attachment of this character, which 20 is simple in its construction, thoroughly reliable and efficient in operation, readily and easily applicable to a fire door, being possessed of few parts, strong, durable, and inexpensive to manufacture and install.
With these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings, which disclose the preferred embodiment of the invention, and pointed out in the claim hereunto appended.
In the accompanying drawings:
Figure 1 is a fragmentary vertical sectional view through a furnace, boiler or the like and its 35 fire door showing the attachment constructed in accordance with the invention applied thereto.
Figure 2 is a sectional View taken on the line 2 2 of Figure 1 looking in the direction of the arrows.
Figure 3 is an elevation of the baille constituting a part of the attachment, being in an assembled condition.
Figure 4 is a sectional View taken on the line 4 4 of Figure 2 looking in the direction of the arrows. v
Figure 5 is an elevation of the air inlet mouth removed from the door.
Figure 6 is an exploded elevation of the baie with the sections thereof in correlated disposition with respect to each other.
Figure' 7 is a top plan view partly in section of the attachment.
Figure 8 is a side elevation partly in section of the attachment.
Figure 9 is an exploded elevation similar to Figure 6 with a part removed and looking toward the opposite side face of such baffle.
Figure 10 is a fragmentary sectional view taken on the line Ill- I0 of Figure 9 looking in the direction of the arrows.
,Figure 11 is a fragmentary sectional View taken on the line II-II of Figure 9 looking in the direction of the arrows.
Similar reference characters indicate corresponding parts throughout the several views in the drawings.
Referring to the drawings in detail, A designates generally a portion of a furnace, boiler, stove or the like of any suitable construction or type and within is lthe usual fire pot, combustion chamber, re door opening and fire door, portions of these being indicated at I 0, II, I2 and I3, respectively, and constitute no part of the present invention, being illustrated merely for an understanding of the attachment constituting the present invention as hereinafter fully described.
The attachment comprises an air inlet mouth unit I4 in the form of a frame walled at its top, bottom and sides orends, being entirely open within these walls through the front and back of said unit while the front of the latter is beveled or inclined outwardly from the back.
Precast with the unit I4 at opposite sides thereof are perforated attaching ears I5 for accommodating fasteners I 6, these being also accommodated in the door'I3 so that the unit I4 can be ma-de secure thereto at the proper location and in the locating of such unit the door I3 is formed with an opening I1 registering with the said unit, the latter being at the outer side of the door.
Precast with the top of the unit I4 are pivot lugs or ears I8, each accommodating a pivot I9 for the vertical swingable mounting of a closure 20 for the said mouth unit I4. This closure 20 is operated in any suit-able manner Afor regulating the supply of air through the mouth unit I4 to the interior of the furnace, stove or the like through the fire door I3 at the opening registering with said unit I4.
The attachment further comprises an inside fire liner or baille for the lire door I3 and comprises the precast sections 2|, 22, 23, 24 and 25,
respectively, which are adjustably intertted with each other to increase or decrease the size of the said liner or baffle in the fitting thereof with the door I3 in a manner hereinafter described.
The sections 2l, 22, 23 and 24 are adapted for edge to edge disposition with respect to each other and similarly the section 25 relative thereto while the said sections 2l, 22, 23 and 24 are provided with overlap wings or extensions 26, 21, 28 and 29, respectively, these allowing assembly of the liner or bame in the grouping of its sections 2l, 22, 23, 24 and 25 for increasing or decreasing the size of said liner or baille in assuring proper fitting to the door I3 in conformity with its size. The section 25 fits between the sections 2l, A 22, 23 and 24 and overlie the overlaps 26, 2, 23 and 29, respectively, at one side of the liner or baffle, preferably at the side next to the door I3 when the latter carries the liner or baille.
The sections 2l, 22, 23 and 2Q are bolted or otherwise fastened to the section 25, as at 3U, for the uniting of all sections with each other in adjusted relation one to the other. When the section 25 has been removed from association with the sections ZI, 22, 23 and 24, the baffle or liner can be brought to a minimum size for the fitting thereof to a door of small size.
The sections 2l, 22, 23 and 2li together with certain of the overlap wings are provided with end and top anges 3l and 32, respectively, for abutment with the inner side of the door I3 spacing the liner or baffle from the door and forming an inlet air -passage 33 leading downwardly and opening into the combustion chamber II below the said baille or liner and this passage 33 communicates with the air inlet mouth Ill at the upper most portion thereof when the liner or baille is on the door I3.
The liner or bafile is made fast to the door I3 at the inner side thereof by hanger bolts 34,
When the closure 23 is in open position, air from without the furnace, boiler, stove or the like is admitted through the mouth l, ilows downwardly through the passage 33 between the liner or baille and the said door and discharges into the combustion chamber II at the front of the fire pot I directly over the fuel therein for consumption of gases and smoke Within the furnace, boiler, stove or the like.
The sectional make-up of the liner or baille enables the precasting thereof so that such liner or baffle is adaptable for use in connection with re doors of different sizes, the ends of the passage 33 and top thereof above the mouth unit I 4 when the said liner or baille is carried by the door I3 or permanently closed while this passage opens between the door I3 and the liner or baille at the lowermost portion of said door for communication at this point with the combustion chamber II next to the front of the fire pot I0 within said furnace, boiler, stove or the like.
By creating the passage 33, as is clearly dis'- closed in Figure 1 of the drawings, the required volume of air from without the furnace, boiler, stove or the like is admitted to the interior or the combustion chamber of the same, the volume being regulated by the closure 20 at the will of the user of the said furnace, boiler or the like.
What is claimed is:
An attachment for a furnace or stove re door having an opening therein, comprising a sectional body fo'rming a bafe for fitting the door at the inner side thereof and having top and opposite end flanges for contacting the said door above and at opposite sides of the opening therein with the bottom of the said baille spaced from the said door, extensions on the sections offset therefrom for the overlapping engagement of the said sections with each other, means for fastening the sections and the extensions together, and a removable element correlated to the said sections and the extensions when the said sections are in overlapped relationship and having jointure with the said extensions.
