2 Claims.
My invention relates to improvements in heating devices and more particularly to stoves or furnaces.
One of the principal objects of my invention is 6 to provide a heating device equipped with means located in proximity to the fire-box section of the device for heating air, thus minimizing the discharge of heat therefrom into the chimney.
Another object of my invention is to provide a device of the above described character which is simple in construction, durable in use, efficient in operation and economical in manufacture.
Other objects and advantages will be apparent from the following description, appended claims and annexed drawing.
Referring tothe drawing wherein like reference characters designate like parts throughout the several views:
Figure 1 is a longitudinal sectional view of my invention.
Figure 2 is a sectional view taken on the line 2--2 of Figure 1.
In practicing my invention I provide an elongated hollow body 5, the lower section of which constitutes a fire box for receiving therein suitable fuel whereby the device is operated. The body is fashioned with side, front, rear, top and bottom walls 6, l, 8, 9 and I0 respectively. Said front wall I adjacent the bottom wall I0 is provided with a draft opening H controlled by the adjustable damper t2. Above the draft opening H the front wall I is also fashioned with a fuel opening l3, the latter being closed by the usual door l4 and whereby fuel may be introduced into the fire box. The rear wall subjacent the top wall 9 has secured thereto a conical shaped and horizontally extending casing 15 extending inwardly and terminating in proximity to the inner 40 face of the front wall I. Said rear wall is fashioned with an opening l6 effecting communication between the interior of the casing l5 and the atmosphere. Located within the casing l5 and centrally thereof is a smoke pipe H, the front end 45 of which terminates flush with the front end of the casing l5 and is sealed thereto whereby to preclude smoke from entering Within the casing l 5 from the fire box. The front end of the smoke pipe I! is open and the rear end extends an ap- 50 preciable distance beyond the rear wall 8 through the opening [6 thereof and is connected to a vertically extending chimney or pipe It, the latter being provided with a damper ii! at the upper end thereof as clearly illustrated in Figure 1 of W the drawing; The opening l6 serves to permit air (Cl. 126--l09) heated within the casing i5 being communicated to the atmosphere.
The top wall 9 of the body is of an arcuate configuration and is fashioned adjacent the front and k rear walls with ports 20 communicating, by means of pipe sections 2|, to similar ports 22 formed in the lower wall of an elongated cylindrical drum 23 positioned above said body 5. The drum 23 is fashioned with a centrally disposed cylindrical shaped shell 24 having open front and rear ends 10 and coacting with said drum to form a circumferentially extending heating chamber 25. Said heating chamber, at the rear upper end thereof, is connected to the pipe I8 by means of an elbow 26 equipped with a damper 21. The upper face of 15 the drum 23 adjacent the front end thereof is fashioned with a threaded connection 28, the latter having threaded thereon an aperture cap 29 operable by means of a handle 30 and interposed between said cap and connection 28 is a relatively thin disk of metal 31 which serves as a seal for the cap. It is to be understood that said disk 3! may be replaced from time to time as the latter becomes burnt out due to the heat. Upon removal of the cap and disk, the connection 28 25 serves as an opening for inspecting the interior of the drum 23. The front wall 1 of the body 5 is formed, above the opening I 3, with a clean-out opening normally closed by a removable threaded plug 33 whereby the pipe I1 may be cleaned. Ex- 30 tending through the front wall 1 above the cleanout opening and subjacent the top wall 9 is a rearwardly extending end section of a pipe 34, the rear end of which communicates with the interior of the casing I5 adjacent the front end of the latter whereby to effect a circulation of air therethrough.
In use, the fuel is maintained within the firebox at a level in proximity with the pipe I! and the lower section of the casing l5 whereby to subject the casing the maximum heat from the fire. The heat and smoke from the fire rises about the casing 15 and enters the passage or chamber 25 of the drum 23 thus heating the walls of the drum and shell 24. When the walls of the drum and shell are thus heated, heat radiates therefrom and in the instance of the shell the heat is transmitted without the shell through the horizontally extending aperture thereof. The smoke from the fire enters the front end of the pipe ll, substantially simultaneously with smoke entering the drum 25, and is conducted therefrom into the chimney It in a horizontal direction thus maintaining the pipe in a heated condition and which coacts with the casing I5 to 5 conserve the heat within the latter and minimize discharge of heat into the chimney. During refiring of the device, the damper 21, which is normally maintained partially closed, is fully opened to permit excess smoke to escape from the drum 23 through the elbow 26 into the chimney I8 and to accelerate burning of the fuel and resultant quick raising of the temperature within the device. However, after refiring the damper 21 is operated to the partially closed position to minimize escape of heat from within the drum into the chimney l8 through the elbow 26.
It is to be understood that smoke rising within the drum 23 will be circulated therein into the fire-box by means of the pipe sections 2 I, thereby maximizing the heating of the drum and shell.
From the foregoing it will be apparent that I have provided a simple and eflicient heating device whereby the heat from the fuel is conserved and is distributed therein in a manner to efiect maximum heating efficiency. It is to be distinctly understood that various changes and modifications in the construction and arrangement of the parts may be resorted to without departing from the spirit of the invention or scope of the appended claims.-
What I claim is:
1. A device of the character described, comprising, an elongated horizontally extending body fashioned with top, bottom, front and rear walls, an open end casing secured to said rear Wall and extending horizontally towards said front wall and terminating in proximity to the latter and Within said body, said rear Wall formed with an opening registering with the open rear end of said casing to effect communication between the latter and the atmosphere, a smoke pipe secured to said casing at the front end thereof and closing the latter, said smoke pipe extending centrally and rearwardly through said casing for communication with a chimney without said body, said body having a fire box within the lower section thereof for maintaining burning fuel therein in proximity to the lower portion of said casing whereby to eifect a concentration of heat above said casing, said front wall fashioned with a draft opening adjacent said bottom wall for coacti-on with said top wall to effect discharge of smoke through said smoke pipe, and means communicating with said casing for supplying the latter with air to be heated.
2. A device of the character described, comprising, a hollow body having walls one of which is formed with an opening, a casing having oppositely disposed open ends and with one of the latter secured to said last defined wall and surrounding said opening whereby to effect communication between the casing and the atmosphere, said casing extending towards another of said walls and terminating in proximity to the latter and within said body, a pipe secured to said casing and closing said end of said casing adjacent said last mentioned wall, said pipe extending centrally through the casing and said opening for communication with a chimney without said body, said body having a fire-box section for maintaining burning fuel therein and in proximity to said casing whereby to effect a concentration of heat about said casing and said pipe, and means communicating with said casing for supplying the latter with air to be heated.
