HEATING AND VENTILATINGi APPARATUS,

SPECIFICATION forming part of Letters Patent N 0. 692,164, dated January 28, 1902.

Application filed July 10,1901. Serial No. 67,712. (No model.)

To all whom it may concern:

Be it known that I, JOHN MORTON MILLER, of Baldwin, in the county of Douglas and State of Kansas, have invented a new and useful Improvement in Heating and Ventilating Apparatus, of which the following is a specification.

My invention is in the nature of an improved heating and ventilating apparatus designed to furnish the rooms of buildings with fresh air from out of doors heated to a suitable temperature and to carry away the stagnant or dead air from the rooms; and it consists in the peculiar construction and arrange ment of the various parts-of the device,which I will now proceed to describe with reference to the drawings, in which- Figure l is a vertical longitudinal section of the apparatus. Fig. 2 is an underneath perspective view of the stove and its attached parts, the outer casing being removed. Fig. 3 is a detail of the ventilatingdamper to the stove, and Figs. 4 and 5 are details of the stove-damper.

In the drawings, D represents a horizontal conduit or flue, which is made of sheet metal and is placed beneath the floor with its upper surface on a level with the floor-line. This conduit opens at one end a through the Wall of the house, so as to be in open communica" tion with the outer fresh air, which it takes into the room to 'be heated. The other end of the conduit has on its horizontal surface a register grating I), through which the dead stagnant air of the room is carried away.

At an intermediate point between the inletopenings or and b there is mounted upon legs ll an outer casing for the heating-stove, said casing composed of side walls I and a bottom 1. Into an opening in the bottom of this casing a short vertical pipe G is inserted and connects it with a corresponding opening in the top of the. conduit D.

Inside the casing I I there is mounted on legs lo the central fire-chamber or stove F. This fire-chamber has its side walls f f spaced apart from the outer casing I by corrugated or zigzag strips of metal J, running around the upper edge.

Under the bottom f of the fire-chamber is arranged in horizontal middle position alon gitudinal flue H, which at one end communicates with a vertical ventilating-flue V and at the other end communicates with a double air-draft flue h h, which takes air into the fire-chamber to support combustion. The flue H communicates with the bottom of flue h. Flue h communicates at the top through a valve, as hereinafter described,with a downdipping flue h, and this flue h opens at its bottom into the bottom of the fire-chamber F. From the top of the fire-chamber a smoketlue s emerges and after turning at right angles communicates with the chimney-flue O, which also communicates with the ventilating-flue V through a damper c. p

In the top f of the tire-chamber a chargingopening is formed, through which fuel is introduced. This consists of a short section of pipe 01', covered by a horizontally-swinging door d.- On a level with this door a top plate R is arranged, which extends over the whole stove and is flanged downwardly at its outer edges and acts as a reflector to throw the heat downwardly.

In the center of the flue H under the firechamber there is formed an opening with which communicates a pipe E, of smaller diameter than G, through which it concentric ally passes. Just below pipe E a partition is formed in the conduit D, consisting of a horizontal part b and a vertical part b. vertical part b prevents communication between the opposite ends of the conduit D below the horizontal part b The'pipe E opens through the partition 6 so as to be in communication with the end I) of the conduit D. The horizontal partition I) has at its opposite ends the hinged flap-dampers B and B. When the damper B is up, as shown, the end I) of the conduit communicates only with pipe E, and when the damper B is horizontal, as in dotted lines, the end I) of the conduit communicates both with the pipe G and the pipe E. Then the damper B is horizontal, as shown, the fresh-air end a of the conduit communicates with the pipe G, and when the said damper B is up, as indicated in dotted lines, the fresh-air end a of the conduit is cut off entirely from the pipe G.

To regulate the admission of air to the stove for combustion, a rotary segmental draft- The damper is used, as seen at M, Fig. 4. This damper has two opposite open spaces m m and two alternate blank spaces 12 n, which may be turned into or out of registration with two corresponding openings m m in a partition-plate N, placed across the top of the two fines h h, with the openings m mjust above the tops of these flues. An axial rod 0 is attached to the damper M and extends through the top of the stove in the form of a handle, by which the damper is turned. When the damper is turned so that openings m and m coincide, the fine h is in communication with h, and when. said openings are turned out of registration flue his cutoff from h and air is cut ofi from the fire-chamber, so as to arrest combustion.

Wood or other fuel is burned in the firechamber F by air fed through fines h h, the smoke passing out at s and the ashes being re moved from time to time by a dipper through the charging-door (Z, or, if desired, a separate ash-door in the side may be provided.

The operation of this device as a heating and ventilating apparatus is as follows: Damper 0 being closed, damper B being up, and B down, the cold fresh air comes in at a from the outside and passing into pipe G distributes itself around the stove, as indicated by the full arrows, and striking the reflector R is thrown downwardly into the room heated. The dead foul air, which naturally lies near the floor, passes down gratingb and entering the pipeE passes to due H and thence through fines h and it into the stove to support combustion, as shown by the dotted arrows. When the damper M is closed and this foul air is not used for combustion, then it passes to the left in fiue H and up flue V to the chimney, damper 0 being opened for this purpose. Dead air may be used for combustion and also be carried up flue V at the same time by having both dampers M and 0 open. If the air in the room is not sufficiently foul to require expulsion from the room, then it may be reheated with an economy of fuel, as follows: Fresh-air damper B is raised, as sho .vn in dotted lines, so as to cut off the end a of the conduit from the pipe G, and damper B is lowered to a horizontal position. The air from the room now entering at 6 passes partly through pipe E to support combustion and partly into the pipe G to be reheated and discharged into the room again.

To work the dampers B 13, they may have separate handles projecting up through the top of the conduit D, or they may, as shown,be both connected to a'single lever P by pullrods r, so as to act together in opposite directions.

In making use of my invention any kind of a stove, furnace, or other heating appliance may be used in the place of the fire-chamber F, and for some of the purposes of myinvention even a steam-radiator or hot-water coil may be substituted therefor.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination with an air-conduit along the floor, one end of which conduit is open to the outer air, and the other end open into the room; of a partition-With dampersin said conduit between said openings, and a heating and ventilating device located above the same and having concentric foul-air and fresh-air passage-ways communicating with the conduit on opposite sides of the partition the foul-air passage-way opening into and taking air from the room, and the fresh-air passage-way opening through the external walls substantially as described.

2. The combination with an air-conduit along the floor, one end of which is open to the outer air, and the other end open into the room; of a partition with dampers in said conduit between said openings, two vertical concentric pipes connecting therewith and opening on opposite sides of said partition and a heating and ventilating device, one of said concentric pipes being in communication with the air-heating spaces of the heater and the fresh-air side of the partition and the other pipe being in communication with the fire-chamber and smoke-flue thereof and the foul-air side. of the partition substantially as described.

3. The combination with a horizontal airconduit having its opposite ends opening into the outer air and the room as described; of a right-angular partition U19 having at its opposite ends the dampers B B, means for working these dampers, a central pipe opening through the partition to the foul-air end of the conduit, and an outer pipe inclosing the central pipe and opening on the fresh-air side of the partition, and a heating and ventilating device mounted above these pipes substantially as described.

4:. The combination with the conduitD having fresh-air and dead-air inlets at opposite ends,and separating-partitions b b with regulating-dampers B B as described; of two concentric pipes E G opening on opposite sides of the partition, the outer casingII opening into pipe G, the fire-chamber F having bottom flue H and Vertical end tlues 71 7t and V communicating with the pipe E, spacing devices J arranged between the fire-chamber and outer casing, and a reflecting-top R extending over the whole device a little above the outer casing substantially as shown and described.
