The door D is provided with a damper or valve E for admitting cold air when desired. The head of the flue-box is also provided with small hand-holes closed by doors or valves I, whereby access may be had to the interior of the upper fines.
The gaseous products produced by the combustion of fuel in the fire-pot pass upwardly from the fire-pot into the upper-flue box, where they are divided by the central partition or flue-plate N, the divided cur-' rents of gas passing around the rear ends of the partitions or flue -plates M M, thence downwardly through the vertical flue-pipes into the base-fines f f. The gases, having thus passed over an extended area of metal in the various fines, are largely deprived of their heat and are permitted to escape from the base-fines into a smoke-pipe at the rear of the furnace, which leads to a chimney in the usual manner.
The rear end of the upper-flue box is pro.- vided with an aperture 0, which communicates with an upper branch of the smokepipe when the flue-box is inserted within the casing. This upper branch of the smokepipe is controlled by a valve or damper r, Fig. 2, which whenopen permits the gases to pass directly into the smoke-pipe from the flue-box without passing through the vertical flue-pipes or the base-fines. When the valve r is closed, the gaseous currents-are caused to pass through all the flues on their way to the smoke-pipe. The flue-surfaces thus become highly heated, and the air inclosed be-' tween the casing and the lire-pot and fines is raised to a high temperature by contact with the heated surfaces and rises through the distributing-pipes a, whence it may be conducted to desired points.
The distributing-pipes a connect with the top of the casin g and may be as many in number as desired within the capacity of the furnace. Air at a comparatively low temperature is supplied to the interior of the casing through the inlets h, which extend along the bottom of the sides of the 'casing. A short distance above the inlets h we provide defiectors XV, arranged obliquely within-the casing and coni-erging at the top toward the firepot, whereby the entering currents of air are directed against the fire-pot and under the overhanging sides of the upperfiue-box, causing them to traverse an irregular path and bringing practically all of the air into contact with the most highly-heated parts of the apparatus.
hen desired, the casing may comprise an inner wall B in connection with the outer wall A, the two walls being separated by an inclosed air-space d, the inner wall B being provided with inlet-apertures K at the bottom and outlet-apertures K at the top to per mit circulation of air in the inclosed air-space d. The inclosed air-space d prevents loss of heat from the furnace by acting as a nonconducting shield. The vertical flue-pipes are supported at their lower ends by clamping split rings '12, which prevent the disarrangement of said pipes by the withdrawal or insertion of the upper flue-box.
F F are doors closing apertures leading into the base-fines, which have the function of cold-air drafts and also permit access to the interior of the base-fines when it is desired to clean the same.
What we claim as new, and desire to secure by Letters Patent, is
1. In a hot-air furnace, the combination with abase and lower horizontal fines extending from front to rear on opposite sides of the ash-pit in the base, and a casing mounted upon the base and provided with a front aperture; a fire-pot and vertical fines connecting at the lower end with the base-fines; of an upper flue-boX located within the casing and removable through the front aperture therein and having flues extending from front to rear and provided with bottom apertures com mu nicating respectively with the fire-pot and the upper ends of the several vertical flues, substantially as described.
2. In a hot-air furnace, .the combination with a fire-pot; a base provided with horizontal flues; vertical flue-pipes communicating at their lower ends with the base-fines; an inclosing casing having a front aperture; a smoke-pipe at' the rear of the casing having an upper branch, and a lower branch communicating with the base-fiues; and a damper in the upper branch of the smoke-pipe; of an upper flue-box removably inserted in thefront aperture in the casin g and provided with fluepartitions, an aperture in the rear end and apertures in the bottom communicating respectively with the upper branch of the sun okepipe, and the fire-pot and upper ends of the vertical flue-pipes, when the flue-box is inserted within the casing, substantially as de-' scribed.
