Application filed February 20, 1918. Serial No. 218,228.
Be it known that I, ConYDoN IV. SExroN, a. citizen ofthe United States, residing at Nayncsboro, in the county of Franklin and State of Pennsylvania, have invented a new and useful Improvement in Devices for "Utilizing \Vasted Heat, of which the following is a specification.
l ly/ invention is designed to utilize for heating purposes the waste gases escaping into chimneys, stacks or lines from stoves, ranges, furnaces and otheiiheatin'g apparatus.
The invention consists in a tubular heating drum, so called, for lack of a better name, interposed in the smoke pipe or flue of a heating apparatus, through which the smoke is circulated in connection with air currents before it is allowed to escape finally; the drum being so arranged or located as to serve as a heater, as hereinafter explained and claimed.
In the accompanying drawings illustrating the invention, in the several figures of which like parts are similarly designated, Figure 1 is a side elevation, partly in section at the top, and Fig. 2 is a partly mutilated top plan view of one form of heater.
I have illustrated only one form ofheater embodying the principle and modes of op eration of my invention, and it is here noted that variations are deemed to be within the spirit and scope of the invention and in cluded in the claims hereinafter made.
In the construction shown, the drum is composed of an outer closed box 1, of suitable material, and an inner shell 2 arranged within the box and spaced apart therefrom on all sides. The outer box has an arched or other suitable top 3, which, if desired, may be removable. In this top is the longitudinally arranged smoke-flue or pipe 4: having the damper 5 arranged transversely therein j ust beyond a collar 6 which affords communication between the smoke-flue and the interior of the shell 2.
The shell 2 is provided with a series of vertically disposed air-tubes 7 which open at the top into an inside hood 8 and at the bottom into the space between the inner shell and the outer box. The smoke-flue or pipe 4: also extends through this hood 8. The interior of the shell is further divided into any number of compartments by means of battle plates 9 and 10 preferably extending alternately from the top and bottom of'the *shell'so that the Waste gases, smoke, or prodnets of combustion entering the shell through the'collar 6 circulate around the tubes 7 in one compartment and thence under the bai'lie plate 9 into the next compartment and around its tubes and thence over the baflie plate 10 into the next compartment and around its tubes and finally escape through the tube 11 into the extension '12 of the smoke-flue 4, and so on to the chimney, stack or other flue.
13 is a pipe entering the top of the outer box o ca ng andmmmunicat ns w h the space therein between said box and the inner shell to supply atmospheric air to the air tubes 7 of the inner shell, and 14: is a smaller pipe within pipe 13 opening into the hood 8. This hood receives the air admitted through pipe 13 and heated bymeans of the waste gases within the apparatus as the air passes up through the air-tubes 7 into the hood, and from this hood the thus heated air may be conducted to a distant place for distribution through a register or other means for heating purposes.
It will be seen that otherwise wasted heat of a heating apparatus of any kind may be efficiently utilized for heating air that may be distributed either by radiation from the auxiliary heater or conducted therefrom to a distant point.
In the construction shown the damper admits of being turned so as to permit the smoke or waste gases to pass directly through the apparatus without circulation whenever that is desired.
By the means described a very simple and economical apparatus is provided for utilizing the waste gases from various kinds of domestic and other heaters.
What I claim is 1. A device for utilizing wasted heat, comprising anouter box, an inner shell arranged within said box and spaced apart therefrom on all sides and having a hood at its top, said shell provided with air tubes opening at opposite ends respectively into' the hood and the bottom space between the box and shell, means to introduce heated gases into said shell, and means to provide for the escape of the gases from said shell when the heat is spent.
2. A device for utilizing wasted heat, comprising an outer box, an inner shell arranged within said box and spaced apart therefrom on all sides and having a hood at its top, said shell provided with air tubes opening into the bottom space and hood at opposite ends, and battle plates interposed between said air tubes to compel circulation around the same, means to introduce heated gases into said shell. and means to provide for the escape of such gases from said shell when the heat is spent.
A device for utilizing wasted heat, comprising an outer box, an inner shell arranged within said box and spaced apart therefrom on all, sides and having a hood at its top, said shell provided with air tubes opening at opposite ends respectively into the hood and. the bottom space between the box and shell, means to introduce atmospheric air into the space surrounding the shell, means to introduce heated gases into said shell to heat the air so introduced, means opening into the hood to convey away the heated air for useful purposes, and
means to provide for the escape of the gases from said shell when the heat is spent.
4. A device for utilizing wasted heat, comprising an outer box, an inner shell arranged within said box and spaced apart therefrom, means to introduce air into said space, said shell provided with air tubes opening into said space at one end, a hood mounted over the inner shell into which the other ends of said air tubes open, and battle plates interposed between said air tubes to compel circulation around the same, a pipe arranged across the apparatus within the hood and communicating with the interior of the shell to introduce the heated gases into said shell, and means to provide for the escape from. the shell of the spent Waste gases.
