SPECIFIFATION forming part of Letters Patent No, 71 1,566,dat ed October 21, 190
. Application filed March 7,1902. Serial No. 97,171. (No model.)
To all whom, it may concern;
Be it known that I, CLARK D. HAZARD, a citizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Heating-Furnaces; and I do hereby declare the following to'be a full, clear, and exact description of the invention, such as will enable others skilled .in the art to which it appertains to make and use the nace will continue to supply heat even after the fire is out.
A further object is to provide meansby the storing of heat whereby the amountof heated air delivered can be increased or-diminished regardless of the amount of live coals in the fire-box.
Generally speaking, the furnace consists of a fire-box, a secondary heating-chamber, through which the flue extends in atortuous course, and a construction of checker brick-5 work within said chamber and around the flues, whereby the heat is absorbed by the checker brickwork and the air in the spaces between the bricks, so that the heat generated is retained or stored'and may be used as desired.
In the accompanying drawings, Figure l is a longitudinal vertical section of the furnace. Fig. 2 is a vertical cross-section thereof on line 3 3 of Fig. 1. Fig. 3 is a horizontal section. v
Referring specifically to the drawings, the fire-box is indicated at 6, having the usual parts suitable thereto. A flue A leads from the fire-box into a radiating-chamber, which is separated from the fire-box by a cross-wall and to clean the flues.
6% After leaving the fire-box the flue A leads vertically downward to a cross-flue B, which extends across the radiating-chamber-at or near thebottom thereof. Similar lower crossflues G and K extend across the radiatingchamber and are connected to corresponding top cross-fines E,I, and M by inclined fiues D, F, H, andJ. The connections are at 0pposite ends of the'topand bottom fines alter- 6o nately, so that a long and tortuous flue is formed through which the 'productsof com bustion pass. The last bottom flue K is connected by a vertical flue L with a flue M, which extends through the wall of the casing to the chimney. A dead end flue Crises from the end of the flue B opposite to the flue D, and this dead end has no function except to increase the radiating-surface. It is, however, provided with a small gas-outlet a, leading to the flue E.
. The radiating-cha mber and fire-box are inclosed by suitable walls, which are preferably formed of a sheet-steel casing (indicated at 7) 'inclosed by a brick wall 8. The radiatingchamber is filled around the flues with checker brickwork, (indicated at 9.) This is an important feature-of my invention and serves to give the furnace its heat-retaining qualities. The heat is absorbed by the bricks So of the checker brickwork and also by the air in the spaces between the bricks. Outlet service-pipes, (indicated at 9 provided with dampers 10, extend through the top wall of the furnace and communicate with the radiating-chamber. Air-inlets (indicated at 11) extend through the walls at the bottom of the furnace. The lower tier of cross-flues are extended through the side Walls and are provided with vents 12 to control the draft 0 The heat absorbed by the checker brickwork andthe airin the interstices thereofis stored or retained within the walls of the radiating-chamber and may be served at pleasure by manipulation 5 of the dampers 10. By actual experiment it i has been found that the prod-nets ofcombustion leave the radiating-chamber quite cold, whereby a great saving of fuel is efiected. The course of the air through the interstices mo of the checkered brickwork is crooked and long, so that the heat absorbed by the bricks is thoroughly diffused to the air, and heated air may be drawn from the furnace for several hours after the fire has been extinguished; also, since the heat generated is stored it may be drawn on at any time irrespective of the state of the fire in the fire-box.
The furnace has many practical advantages of construction in that the parts are formed of cheap and plentiful materials, which are readily procurable at almost any place.
What I claim is.
1. In a furnace, the combination with a fire-box and a radiating-chamber; of a flue extending from the fire-box through said chamber, said flue comprising horizontal top and bottom sections across the chamber and substantially vertical sections at the sides of the chamber connecting the horizontal sec- CLARK D.
