HEATING UNIT Filed March 8, 1968 I8 mveuraa HARMD W. HAWNEIBAUN United States Patent U.S. Cl. 126120 Claims ABSTRACT OF THE DISCLOSURE A heating unit which can be used in place of a conventional fireplace in a home, which can utilize wood as fuel, which operates efficiently and produces a beautiful and decorative effect while producing light as well as heat.
SUMMARY OF THE INVENTION My unit comprises a firebox in the shape of a hollow bowl open at the top end and if necessary supported at its bottom by a vertical pedestal. A hollow vertical cylinder open at both ends is secured by its bottom end to the top end of the bowl. A vertical truncated cone open at both ends is secured at its bottom and larger end to the top end of the cylinder. A chimney or smoke stack is secured to the top and smaller end of the cone.
The bowl is provided with an air ventmanually ad justable in area.
The cylinder is provided with a plurality of vertical clear or colored glass panes or windows having a plurality of vertical elongated air intake openings therebetween.
When fuel is placed in the firebox and burned, the box radiates heat efiiciently and in suitable quantities for use. The air entering the intakes swirls around producing a beautiful lighting effect suitable for illumination and at the same time keeps the windows clean and free of smoke while eliminating most of the ashes via the chimney, thereby minimizing clean out problems. I call my unit the Side Winder.
BRIEF DESCRIPTION OF THE DRAWINGS In the drawings:
FIG. 1 is a perspective view of my unit;
FIG. 2 is a view through 22 in FIG. 1;
FIG. 3 is a view through 33 in FIG. 2;
FIG. 4 is a detail perspective view of the cylinder;
FIG. 5 is a detail cross sectional view of the cylinder; and
FIG. 6 is a detail view of the air vent.
DETAILED DESCRIPTION OF PREFERRED EMBODIMENT Referring now to FIGS. 1-5, a firebox in the form of a hollow metal bowl 10 open at the top end and having an air cooled fire ring 12 welded to the bowl. The bowl 10 is supported at its base by a vertical pedestal 14 having an enlarged base 16. The ring is about four inches high, about five inches inward of the base of the windows (see below) and holds or contains the fire in the bowl.
A generally horizontal hollow vent tube 18 open at both ends extends inwardly to the interior of the box from the outside. A hollow tube plug 20 sealed at one end 22 and open at the other is manually slidable in the outer end of the tube. Tube and plug each have openings 24 in their outer walls whereby the registration between these openings can be manually adjusted to vary the area of the vent.
A hollow vertical cylinder is formed by eleven vertical panes or windows 26 of clear or colored fire proof glass so arranged as to define in cross section a regular 3,499,432 Patented Mar. 10, 1970 polygon of eleven sides. These windows are all secured at bottom to the open top end of the box and are secured at their top end to outer and inner horizontal concentric rings 28 and 30.
An inverted hollow truncated cone 36 open at both ends is secured at its lower and larger ends to the rings and at its upper and smaller end to a vertical smoke pipe or stack or chimney 32.
Selected panes of glass define two fixed elongated vertical openings 34 of fixed width which serve as air intakes. One pane of glass 26A is hinged and acts as a door and has another similar opening 34A which can be varied in width as desired.
The Side Winder can be built or fiitted with clear fireproof glass windows, or colored fire-proof of colored shatter-proof glass windows. The glass can be scored in various patterns and cracked or the heat will cause the cracks to' follow the cut lines, but this must be the plateglass with the small one inch stainless steel wire mesh embedded into the plate glass. To get a beautiful erratic pattern on the plate glass shatter proof windows, it is not necessary to score them. Because of the clear ,or colored glass construction of the fireplace, anybody or anything is clearly visible through and beyond it, even while it is in operation. It will fiood a very large living room with ample light to read by or to carry on any other activities. At night twenty-two fires are clearly visible and beautiful from the reflections of these glass windows. The fire light and red light from the embers also causes a sparkling effect on the glassdue to the tiny fissures in the shatterproof windows.
The Side Winder will very nicely and safety burn wood, coal, rubber, old rags, paper, natural gas or anything that will burn. This I have done and the windows stay clean. The combustion is so perfect that the smoke is virtually eliminated which should greatly cut down the smog conditions.
A two inch thick mass of whirling air taken in through inch openings at two windows and one adjustable opening in the door, keeps the windows clean and free of smoke and also eliminates about eighty percent of the ashes up the chimney, making it almost unnecessary to clean out the ashes.
An inner ring 30 in the top of the fireplace serves as a deflector to draw the hot gases away from the top portion of the windows 26 as shown by arow in FIG. 3. My invention has good heat output and will keep an eight room house or larger warm in ten below weather with very little fuel. It is used the year round in this cool climate and has been in constant operation for over two years and in this length of time I have burned three tons of pine woodwhich makes it very economical. Also in this length of time the Side Winder has had no repairs and has caused no troubles of any kind and is entirely safe. No sparks ever get out on the floor. It causes absolutely no fumes or odors of any kind within the home under any conditions.
A flat heat spreader circular flat horizontal plate 31 distributes heat uniformly. The door hinge and the door latch are the only two working parts of my invention.
The underside .of the fire bowl radiates heat downward typically on about one hundred fifty square feet of the floor.
The Side Winder has removable glass windows and is set up or stacked in three parts, which is done in about ten minutes and is ready for use. Its performance is excellent with a six inch stove pipe or larger and a standard flue or chimney. The overall dimension is thirty-four by sixty-six inches, but can be built larger or smaller.
The oxygen consumption is very low, about that of the average wood burning stove. Therefore the amount of warm air taken from the room is very small and very little cold air is drawn in to take its place from the out side of the home.
The Side Winder fireplace is excellent to cook or bake meats and most any other foods of any kind in, by wrapping in aluminum foil and placing the food inside the fireplace just outside of the fire ring. Due to the reflections of radiant heat and fast flow of hot air on all sides of the food it never needs handling or turning and will not burn or scorch even with the hottest of fires.
Our Side Winder fireplace has only one adjustable 16 inch long air intake at the edge of the door. It is adjustable from one inch opening to inch opening and supplies all the draft for the fire and keeps the windows clean.
While I have described my invention with particular reference to the drawings, my protection is to be limited only by the terms of the claims which follow.
