LEONIDAS D. WEST, OF DUNDEE, NEiV YORK.

SPECIFICATION forming part of Letters Patent No. 663,315, dated December 4, 1900.

Application filed August 10, 1900. Serial No. 26,485. (Nomodel-J To whom it 'may concern:

Be it known that I, LEONIDAS D. VEST, of Dundee, in the county of Yates, in the State of New York, have invented new and useful Improvements in Apparatus for Producing Combustion, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to improvements in apparatus for producing combustion, the object being to provide means for inducing a continuous flow of air to a combustion-chamber and heating the same in transit thereto by the products of combustion.

To this end the invention consists in the combination, construction, and arrangement of the parts of an air-feeding apparatus, as hereinafter fully described, and pointed out in the claims.

Referring to the drawings, Figure 1 is an elevation, partly in section, of my invention shown as operatively attached to an ordinary furnace. Fig. 2 is a slightly-enlarged vertical sectional view of this invention as applied to a stove and showing a slightly-modified supporting means and connection to the airinlet chamber. Fig. 3 is a still further enlarged vertical sectional view of the parts seen in Fig. 1, the supporting means and an air-inlet feed being omitted. Figs. at, 5, and 6 are perspective views, respectively, of the parts which form the upper, intermediate, and lower sections seen in Fig. 3. Fig. 7 is an inner face view of the supporting-brace seen in Fig. 1.

As preferably constructed this invention consists of a series of hollow sections 1, 2, and 3, supported within the combustion-chamber of a heater in planes one above the other and discharging into said combustion-chamber, and an inlet-chamber 1, connected to one of the sections for feeding fresh air thereto.

In Fig. 1 I have shown the sections 1, 2, and 3 as suspended within the combustion-chainber a of an ordinary furnace A and as connected to the air-inlet chamber 4 by'a conduit or pipe 5, which serves to partially support said sections and to conduct the air from the air-inlet chamber 4: to the upper chamber of the section 1. In order to additionally support said sections and to permit the same to be properly adjusted for various sizes of combustion-chambers, I provide a brace 6, hav= ing one end adjustably clamped to the inner end of the conduit 5 and its other end engaged with the walls of the combustionchamber and preferably with the walls of the fuel-inlet opening. This brace is preferably formed with separated arms diverging from its upper end, said arms being engaged with the walls on opposite sides of the fuel-inlet opening for permitting the fuel to pass between said arms.

Although the above-described construction of conduit and supporting means is particularly desirable when my invention is used in connection with a furnace, as seen in Fig. 1, it will be apparent that said supporting conduit and brace may be dispensed with when it is desired to use my invention in connection with an ordinary stove or range, and at Fig. 2 I have shown a portion of the top of a range, which may be one of the plates orgriddle thereof, from which the sections 1, 2, and 3 are suspended and held in operative position by a single clamping-bolt, as 7. When used in this connection, I usually provide the cross-piece or griddle of the range with an air-chamber 8, having an inlet-opening 9 and an outlet-opening 10. The walls of this airchamber 8 may be either formed integral with the cross-piece or griddle or maybe detachable therefrom, as may be desired.

The sections 1, 2, and 3 are, as previously stated, arranged in planes one above the other and gradually diminishing in area from the upper section toward the lower section. These air-heating sections may be of any form or size, but preferably consist of hollow substantially lenticular bodies of unequal cross-sectional area formed of oppositely-arranged concavo-convex plates having openings in their adjacent faces for connecting the interior chambers of said sections with each other. The 'upper plate of the upper section is provided with an inlet-opening 11, which is pref erably threaded to receive the inner threaded end of the conduit 5, the outer end of said conduit 5 being connected to the inlet-opening 4, and it is thus apparent that when desired the air is conducted from the air-inlet chamber 4 through the conduit 5 to the interior chamber of the section 1. The opposite or lower plate of the section 1 is formed with an annular flange 12, normally engaged with the upper face of the section 2 for forming an additional air-chamber 13, which communicates with the interior chamber of the section 1 through an outlet-opening 14, formed in the base of the lower plate of the section 1 and preferably of less diameter than the chamber 13.

In devices of this character it is desirable to distribute the heated air over as large a surface as possible in order that the same may be heated to a high degree, and for this purpose I provide the section 1 with a transverse diaphragm 15, having its peripheral edges usually interposed between the upper and lower plates of said section and its intermediate portion provided with apertures for conducting the air from the inlet-opening 11 in the upper plate to the outlet-opening 14 of the lower plate. The upper plate of the lower section 2 is provided with an inlet-opening 16, alined with the opening 14 and serving to connect the chambers 13 with the interior chamber of the section 2. The lower plate of the section 2 is formed with a substantially central opening 17, alined with the opening 16, and with a depending annular flange 20, surrounding said opening and engaged with the upper face of the lower section 3 for forming an additional air-chamber 21, which communicates with the interior chamber of the section 2 through the opening 17.

Arranged transversely within the interior chamber of the section 2 is a diaphragm 25, which is preferably formed of less diameter than said sections and is provided with depending studs or legs 26, normally resting upon the inner face of the lower plate of the section 2 for holding said diaphragm out of contact with the interior walls of the section and permitting the air to pass between the periphery of said diaphragm and the adjacent walls of the lower plate. These diaphragms 15 and 25 are each provided with substantially central apertures alined with the apertures 14, 16, and 17 for receiving suitable clamping means, hereinafter described.

The upper plate of the lower section 3 is provided with a substantially central aperture 27, alined with the apertures 1'7 of the section 2 and is adapted to receive the air discharged from the chamber 21 and conduct the same to the interior chamber of the section 3. The lower plate of the section 3 is provided with a series of apertures 30, form ed of less cross-area than the aperture 27, and they are preferably arranged near the periphery of said lower plate for discharging the heated air in a series of jets to the combustion-chamber.

The upper plate of the upper section 1 and the lower plate of the section 3 are provided with substantially central apertures alined with the apertures 14, 16, 17, and 27 for receiving the clamping means previously mentioned. This clamping means usually consists of a bolt 31, passed through the central apertures of the sections 1, 2, and 3 and is provided at its opposite ends with suitable heads or engaging shoulders, one or both of which may be adjustable lengthwise of the bolt for engaging the upper and lower faces of the sections 1 and 3, and thereby clamping the sections 1, 2, and 3 firmly together. As previously stated, these sections 1, 2, and 3 are formed of unequal area, the section 2 having its periphery extending beyond the periphery of the section 3 and the section 1 being formed of greater diameter than the section 2. Although I have shown but three of these sections detachably connected to each other, it will be readily understood that any number of intermediate sections 2 may be interposed between the upper section 1 and the lower section 3 and clamped together by a single bolt in the mannerjust described. It is also evident that, if desired, the lower section 3 may be also provided with a suitable diaphragm for retarding the passage of the air from the inlet-opening 27 to the discharge-openings 30.

The inlet-chamber 4, previously referred to, is preferably secured to the outer shell of the heater, as seen in Fig. 1, and usually consists of a hollow cylindrical drum having its interior chamber connected to the conduit 5 through an opening 33, formed in the outer shell of the furnace A, which in turn communicates with an additional chamber 34, preferably arranged at the inside of said shell and provided with a threaded aperture for receiving the outer threaded end of the conduit 5. The outer wall of the chamber 4 is usually provided with a series of apertures and a damper 35, pivotally connected to said outer Wall and movable into and out of registration with said apertures.

The means for securing the chamber 4 and damper 35 in position preferably consists of a bolt 36, having one end engaged with the walls of. the chamber 34 and its other end passed through a central aperture formed in the outer wall of the chamber 4 and extended through the damper 35 and provided with a washer or head engaged with the outer face of said damper.

I usually provide the damper 35 with a hollow boss surrounding said bolt and a coilspring arranged within said boss and interposed between the outer head of the bolt and the adjacent faces of the damper for frictionally holding said damper in its adjusted position.

Although the above-described means for connecting the conduit 5 with the air-inlet chamber 4 is desirable in connection with a furnace, it will be understood that the chamber 34 may be dispensed with and that the conduit 5 may be otherwise connected to said chamber 4 and that the clamping-bolt 36 may be otherwise arranged in securing the conduit 5 and chamber 4 in operative position.

In Fig. 2 I have shown an inlet-chamber 40, similar to the chamber Al, which is alined with the aperture 9 of the plate, griddle, or crosspiece previously mentioned, and have also showna single clamping-bolt, similar to the clamping-bolt seen in Figs. 1 and 3, which is extended through the chamber 8 and the airinlet chamber 4 for engaging the outer face of a damper 41, similar to the damper 35, previously mentioned. This bolt serves to hold the damper 4:1 and the sections 1, 2, and 3 in operative position, the opening 11 of the upper plate of the section 1 being alined with the opening 10 of the chamber 8 and the adjacent faces of said upper section 1 and the lower wall of the chamber 8 being normally held in close contact with each other.

In the operation of my invention the air is admitted to the inlet-chamber 4 by means of the damper 35 and is conducted therefrom to the interior chamber of the upper section 1. The air then passes through the apertures in the diaphragm in said section 1, through the apertures 14 and 16 to the interior chamber of the section 2, through the apertures 17 and 27 and the interior chamber of the section 3, and is discharged therefrom through the apertures 30 into the combustionchamber a. r

The operation of my invention will now be readily understood upon reference to the foregoing description and the accompanying drawings, and it will be noted that any number of said sections may be assembled and supported by a single bolt and that the supporting means and other details of construction may be somewhat varied without departing from the spirit of this invention. Therefore I do not limit myself to the construction and arrangement shown and described.

I claim 1. An apparatus for producing combustion comprising a combustion-chamloer, and a plurality of air-heating chambers arranged in planes one above the other and communicating with each other, the upper chambers being of greater cross-sectional area than the next adjacent lower chamber, said chambers having openings for receiving and discharging the air as described.
