HEATING- FURNACE.
SPECIFICATION formingpart of Letters Patent No. 230,837', dated .August 3, 1880.
Application filed April '2, 1879.
To all whom it may concern Be it known that l, J. LEWIS TREFREN, of the town and county of Santa Cruz, and State of California, have invented a Heating-Furnace; and I hereby declare the following to be a full, clear, and exact description thereof, reference being made to the accompanying drawings.
My invention relates to certain improvements in air-heati ng furnaces, such as are used for furnishing heat to churches, halls, or private dwellings; and my improvements consist in certain details of construction, hereinafter fully described, and specifically pointed out in the claims.
Figure l is a perspective View of my heater. Fig. 2 is ahorizontal section. Fig. 3 is a transverse section. Fig. et is a longitudinal section.
The lire-box or box-stove A is made preferably of corrugated iron castings, which gives it a great heat-generating power. A stationary grate. B, is used when wood is burned for fuel, and a revolving grate and tire-brick lining may beemployed when coalis burned. This tire-box has an ordinary ash-box, C, under it, the doors to the ash-pit and fire-box having the usual damper-s, as shown. The fire-boxis inclosed in a heating-chamber, D, formed of corrugated sheet-iron partitions or linings d, reaching from the loor of the furnace on both sides and ends upward, and opening at the center ofthe top, as shown at a. Outside of this is another chamber, E, formed of the linings or partitions e, constructed in a similar manner, and outside of this again are the outer or inclosing walls, F, forming a chamber, G, between the outer` walls and the lining e. Each of the chambers opens into the central one above, as shown at a, and each one is separate from the other. The outer inclosing-walls, F, may be covered, if necessary, with any nonconducting substance, such as cement, asbestus, &c., to more eft'ectually retain the heat in the furnace.
A goose-neck drum or pipe, H, of cast-iron opens into the back end ofthe box-stove, and is carried on an upward incline through the length of the chamber D, and then returns again to the rear upper end and out of the top. This pipe carries ofi' the smoke and products of combustion from the lire-box, and is set inclined to facilitate the draft, the turns being made in gradual curves, as shown.
Projecting through the top of the furnace are the heating-tubes J J', the latter of which leads from the inner chamber, D, through which the heat generated in the furnace may bc led off to different apartments in the building in which the furnace is placed.
Whenever there are too few rooms to utilize all the heating-tubes, those not used may be closed by a cap, b, and the heat passing through those in use is controlled by the valves or dampers c.
A cold-air box, K, extends the length and width of the furnace at its bottom, under the ash-box, and the cold air to be heated is admitted to this box through the opening f. This openingf may communicate with the air ontside the house, so that only fresh air will be used.
Communication between the chambers D, E, and G and the cold-air box K is made by means of slots through the floor of the furnace, these slots being made in each chamber on each side of the lire-box and at the rear end. Slides or valves L control the openings or slots, independent slides being' made for each chamber and at each side and end of each chamber. The side slides or valves are operated by the rods or handles g, and the end ones by the rods or handles h. By means of 'these slides it is possible to cutoff the supply of air from either chamber when more air is being' heated than is needed. When only one or two roonlsare to be heated the supply of air to the outer chamber, for instance, is cut off, and it then answers as asort of jacket to the central chamber, and prevents radiation of heat.
A heater constructed in this manner is very economical in fuel, anda comparatively short time only is required to generate heat. The heat is also under control, and may be properly distributed without waste. The corrugated castings on the outer surface of the firebox and the corrugated sheet-iron linings give great heat-generating power. The cast-iron goose-neck drum or stove-pipe is so arranged as .to retain the first heat passing through the ICO pipe or liue and radiate itin hot-air chambers, preventing itfrom escaping through the smokepipe into the tlue.
By the peculiar system ot'openings from the cold-air box to the hot-air chambers, regulated by sliding valves, only the required amount of cold air may be admitted to the chambers, preventing any heat-deadenin g influence from uuheated air.
By the close-fitting dampers e in the hot-air tubes, near the hot-air chambers, the heated air may be reta-ined from apartments when not required Without any loss attendant in letting it pass to the registers in the apartments themselves. At one ot' the openings covered with a cap a dish of water may beinserted to soften the hot air. By the tire-box and goose-neck drum being made ol" heavy castings, put together in deep grooves set on lire-clay and bolted firmly, and closely-fitted linings to the neel; of the tire-door, all possibility of smoke from firing or smoke-pipe entering the hot-air chambers is grevented.
Vhen desirable the non conducting substance on the outside of the furnace may be omitted from the top and openings made through it, when the furnace can be used as a range for heating water for any purpose.
The corrugated linings and yhot-air chainbers and cold-air openings and dampers may be increased or decreased in number, according to size of furnace and Work required.
The furnace may be made of any size or shape to suit taste or the general architecture of the building.
Any number of hot-air connections may be connected with the chambers, according to the number of rooms to be heated.
The furnace may be placed in a furnace-room or be set in a partition, and each end finished as lire places or grates, the end registers emitting the heat sufiiciently to Warni the two rooms. The hot-air pipes then pass up the openings into rooms above, thus greatly economizing fuel by causing` one ire to do the work of four or tive. The smoke-pipe in this case would pass into a ilue that would come down beside the furnace finished in the partition as an ordinary tire-place and chimney.
I am aware that furnaces have been heretofore known with an inner tire-box and with elose outer shells, forming air-spaces around such fire-box.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. The combination, in a heating-furnace, of the central fire-box, A, located within the inner chamber, of the surrounding and comm unicating chambers E F, and ot' pipe H, leading from the lire-box through said innerand outer chambers, as set forth.
2. In combination with the central tire-box, the inner heating-chamber and the surrounding chambers connected therewith, the pipe H, passing through the said chambers and the airbox K, with the slots and valves L, as set forth.
1n witness whereot1 I have hereunto set my hand and seal.
