. Be--it knownthat W,:M:ICI-IAEL H. BREN- NAN and Jenn J. .BRENNAN, citizens of the United, States, residing at Devils Lake, in the countyof Ramsey and State of North Dakota, .and Girardvillc, in the county of Schuylkill, State of Pennsylvania, respec- :radi'ation of heat in the room or apartment and-t0 save theheat for radiation and power purposes and. economize fuel. at the same time, e p

Another objectisto render the room or apartment more sanitary by shutting off the direct draft .fron'iwthe room or apartment :into the fire, thereby stopping the counter current from. the draft opening, from which when Opemdeleterious gases are discharged into the room or apartment. Also, by utilizing the down draft in the pipe or chimney pure air is brought into the stove for sup porting conibustion. .This dOWI1 draft is also utilized to retard the upward movement of the products of combustion so that practically all of the combustible gases and particlesof carbon driven upward by the flames are consumed, practically only the non-combustible gasesbeing allowed to escape, the same being carried off by;-the up draft in the pipe and. chimney.

This invention applies to heating plants for heat. and power, and the devices hereinafter described may beused in connection with same, the fundamental principle being the increase in radiation by better combustion and less loss of heat from draft, the device resulting in the taking in of sufiicient oxygen for purposes of combustion, and no more. By this means, for the same amount of fuel, a much. greater heat is produced and retained longer.

The invention. will be first hereinafter described in connection with the accompanying drawings, which constitute a part of this specificatioinand then more specifically set forth in the claims at the end of the description.

A preferred form of heating apparatus embodying our invention is shown in the accompanymg drawings wherein- A designates a stove or'fire chamber hav-' HnArING ABPARATUS.

ing a direct draft opening B below the grate C, a direct outlet opening D in the top, and another opening arranged above the fuel level and preferably in the side as at E. The direct draft opening is designed for causing a direct draft when the fire is first started, but is normally closed by a suitable valve F. In the direct outlet opening D there is fitted a pipe G leading to the chimney (not shown). The opening E is provied with a suitable valve Hand communicates with a branch or forked pipe K which is connected to the pipe G some distance, .above the stove. There are no other open- G. The outer walls of this drum are imperforate, but the pipe G has two openings R- and S communicating with its interior. Said openings may be arranged on the same or" on diametrically opposite sides of the pipe, or at some location between so as to obtain different grades of efficiency or regulation. One of those openings is preferably located on a higher level than the other.

hen a fire is started in the stove, the coal or wood may be put in first to form the bottom layer T just above the grate. -The kindling is then put in and forms the second layer U, While the paper constitutes the top layer V. In other words the fire (fuel material) is laid in just the reverse from the usual order. After the paper is lighted, the valve F in the direct draft opening B may be opened for a short time in order to start the kindling to burn freely. Or the fire may be started in the ordinary way. But the reverse order gives better results. The valve F is then closed, and the fire will burn downward, thekindling igniting the coal so that soon the coal is a;, gl owing mass which. will burn slowly and last a long time during which it will radiate intense heat- It has been found that very little heat escapes up the pipe G to the chimney, and that the pipes K and N and drum P remain cool, indicating that practically none of the combustible gases escape.

It will be understood that either of the pipes K and N, or the drum P may be used alone,

that any combination of two of them may be used together, or that all three may be used together, as illustrated in the figure. The theory on which each of said pipes works is that there is a down draft or curplies them with additional oxygen so that.

substantially complete combustion takes place. This is further demonstrated by the fact that very little smoke is discharged from the chimney. The drum P acts in the same way, the fresh air entering it from the pipe G through the upper opening R and returning to said, pipe through the lower opening S. It will be noted thatin view of the facttha't these openings arearranged on diametrically opposite sides of the pipe G, the current of fresh air must travel a spiral course downward'before enteripg the pipe through the lower opening. This spiral and downward movement or currentfis contained in the pipe G causing if anythingan even better mixture of the fresh air with the partly consumed gases, and consequently more efiectually retarding the upward movement of said gases and accomplishing their more complete combustion, than when the pipes K and Nareused alone. Whenever the pipe K is not-to be used, thecurrent ofair.

therein may be cut oil by closing the damper V. The valve'H may be adjusted to suit conditions-independently of the damper W, so as to give the proper action when the damper is opened and the. pipe K is 1n use.

\Vhen the pipes N and K are used together, a

considerable portion of the products of ,com-

bustion and gases not thoroughly consumed which pass'up through the pipe K will enter the upper end of the pipe N, arranged on the opposite side of the pipe G and as shown, also located in horizontal alinement to the upper endof pipeK. Said gases will pass down said pipe N, and be delivered in a downward direction into the pipe G from the lower end ofpipe. N, thus further retarding the escape of unconsu'med'gase's and aidv ing in securing more nearly complete com bustion. 1

It will be obvious, of course, that the improvement herein described maybe attached to any stove of ordinary construction and will not be necessary to construct aspecial form of stove to which the-improvement Y main vpipe when desired.

in be attached as the same may be attached to the ordinary opening in the stove leading to the chimney'and another opening in the stove.

Having thus described our invention,-what we claim as new and desire to secure by Letters Patent of the United States is:

1. The combination with a fire chamber having two openings in its .upper portion and adapted to'be otherwise closed, of a main pipe fitted to one of said openings and leading to achimney, a branch pipe fitted to the other opening and communicating with the main pipe, and a second branch pipe in the form of a loop communicating at both ends with the main pipe,:the )ilIlCtlOIl of the first branch pipe with the main pipe being opposite to and in horizontal alinement with the junction of one end oi the second branch pipe with the main p p 2. The combination'with .a. fire chamber having two openings in its upper portion, p

and adapted to be otherwise closed, of a main pipe fitted to one of said openings and leadmg to a chimney, a branch pipe fitted to the other opening and communicating with'the mam plpe, a second branch pipe in the form ofa loop communicating at both ends with the main pipe, the junction of the first branch-pipe with the main pipe being opposite to andin horizontal alinement with the junction of one end of the second branch pipe'with the -main. pipe, and means .for shutting off the first branch pipe and the 3. The'combination'with a fire chamber having two openings in its upper-portion and adapted tobe otherwise closed, of a main pipe fitted to one of said openings and leading to a chimney, a branch pipe fitted to the other opening and communicating with the. main pipe, and a second branch'pi'pe in the form of a loop communicating at both ends with the main pipe, 'said loop being arranged'on'the opposite side of the main pipe from the first branch pipe and cooperating therewith to regulate the current there through. x y
