CHARLES J. SEGERSTROM, OF ARGYLE, MINNESOTA.

HEATING-DRUM.

SPECIFICATION forming part of Letters Patent No. 762,203, dated June '7, 1904.

Application filed January 16, 1904. $erial No. 189,316. (No model.)

To aZZ whom, u? may concern:

Be it known that I, CHARLEs J. SEGER- STROM, a citizen of the United States, residing at Argyle, in the county of Marshall and State of Minnesota, have invented new and useful Improvements in Heating-Drums, of which the following is a specification.

This invention relatesto a heating-drum for attachment to the smoke-pipe or smokeflue means of a stove; and the primary object of the same is to provide a drum having an organization of elements whereby the products of combustion passing upwardly through the smoke-pipe will be caused to circulate through the drum in such manner that the ,caloric thereof may be practically utilized to heat the lower strata of air within a room or compartment, and thereby more uniformly preserve the temperature of the room without increasing the supply of fuel to the stove or furnace.

- Similar numerals of reference are employed to indicate corresponding parts in the several views.

The numeral 1 designates a stove or furnace of any preferred construction having a smoke-pipe or outlet-flue 2, provided with the usual damper 3. Interposed in the pipe 2 is a drum 4, having upper and lower collars 5 and 6, which are continued centrally into the opposite ends of the drum and project beyond the latter sufliciently for the reception of the sections of the pipe 2. The drum 4 is preferably disposed at an elevation above the stove or furnace and is formed with upper and lower conical chambers 7 and 8, into which the collars 5 and 6, respectively, extend, the said chambers being fully closed except at the points which will be hereinafter specified. The chambers 7 and 8 are secured, respectively, to the upper and lower ends of cylindrical smoke-chambers 9 and 10, the said smoke chambers and conical chambers forming the medium of an elbow 14, said elbow being disposed at an angle to the chamber with which it communicates and to one side of the center of said chamber. The lower end of the conductor or conduit 13 is open, and projecting thereinto is a reduced conveying pipe 15, having a bell-mouth 16 at its lower end, to which h angers 17 are secured and also attached to the lower end of the conductor or conduit The pipe 15, with its bell-mouth, serves to cause the lowermost strata of cold air to flow upwardly into the conduit 13 and provides an extension for the latter, which may be used as an air-conveying means when found necessary. This extension of the conduit 13 is supplied with a damper 18, which may be closed at any time desired, and thereby cause all the cold air to pass into the said conduit from the lower end of the latter. The advantage of this construction is that at times there may be a warm strata of air close to the floor and a colder strata at a slight elevation above the floor or base on which the furnace rests. By the use of the conduit having an extension all the cold air at an elevation above the floor may be heated by causing said air to be conveyed to the drum. After the cold air enters the lower chamber 8' it passes upwill be heated,and the air passing therethrough will also be heated and be given the desired temperature before delivery into the upper chamber 7, and to practically arrive at this result the flues 12 are made as long as possible. The heated air entering the upper conical chamber 7 is fed out into the compartment or room in which the drum is located through openings 19 in the top of said conical chamber at opposite sides of the center, the said openings 19 being surrounded by upstanding collars 20 of materially greater diameter than the openings. The collars 20 are secured in eccentric relation to the openings 19, the said openings being adjacent to the outer portions of the collars, so as to cause the air escaping from the chamber 7 to be thrown against the portions of the collars adjacent to said openings and deflected inwardly to spread the heated air and cause it to flow into the upper part of a room or compartment with less force and noiselessly. It is obvious that considerable upward draft or suction will be created in the drum, and to break up the blowing effect that might ensue the openings 19 and collars 20 are arranged as set forth. Instead of having the drum arranged over the stove or furnace,as shown, it may be interposed in a smoke-pipe length at a distance from the stove and be located in a separate compartment. A material advantage, however, in the heating effect of the drum is derived by positioningit.

over the stove, as shown. The upper air within a room or compartment is also permitted to circulate in and around the fines 11 between the heads of the drum and will thereby be come rapidlyheated. This operation will also result in amaterial eeonomyin the use of fuel. The particular arrangement of the fines is clearly illustrated in the several horizontal sections, and said flues are used to demonstrate principally that the air-fines 12 communicate solely with the conical chambers 7 and 8.

The smoke passing into the lower cylindrical chamber 10 is conveyed through the lines 11 into the upper chamber 9 and from the latter passes off through the collar 12 into the smoke pipe or fine above the drum. As shown by Fig. 2, the collars 5 and 6, respectively, connect with the upper and lower ends of the chambers 9 and 10, and the heat of thesmoke and products of combustion is utilized at every point where possible to increase the temperature of the air passing into the drum.

Changes in the proportions, dimensions, and minor details may be resorted to without in the least departing from the spirit of the invention.

Having thus fully described the invention, what is claimed as new is- 1. A drum for the purpose set forth, having upper and lower heads comprising cylindrical chambers with conical chambered ends, the conical chambered ends being incommunicative with respect to the cylindrical chambers, flues connecting the inner opposing ends of the cylindrical chambers, smaller fines extending centrally through the first-named fines and the said cylindrical chambers and communicating at opposite ends with the conical chambers, the upper conical chamber having outlet means at opposite sides of the center, collars extending centrally through the conical chambers and communicating with the cylindrical chambers, and a conduit attached to the lower conical chamber and having a lower open bottom and extension provided with a damper.

2. The combination with aheating-drum, of a cold-air conduit leading thereto having a lower open bottom, and an extension depending from the lower end of the conduit and provided with a damper, a part of the extension projecting into the lower end of the conduit and of materially less diameter than the latter.

In testimony whereof I aflix my signature in presence of two witnesses.

CHARLES J. SEGERSTROM.
