IMPROVEMENT IN HOT-AIR FURNACES.
Specification forming part of Letters Patent No. 128,555, dated July 2, 1872.
Specification describing a new and Improved Hot-Air Furnace, invented by JOHNSTON MEALEY, of Ogdensburg, in the-county of St. Lawrence and State of New York.
My invention is an improvement in hot-air furnaces made principally of brick, more especially upon that patented by John Gwynn May 8, 1869. Accordingly I fully disclaim whatever is shown or described therein, and desire to restrict myself to the improved construction which is hereinafter described.
Figure 1 is a central longitudinal sectional elevation of my improved furnace. Fig. 2 is a front elevation with the outer wall removed and with a part broken out; and Fig. 3 is a similar rear elevation.
Similar letters of reference indicate corresponding parts. y
A is the outside structure, of` rectangular form, made of brick, with three openings, B,
C, and D, in the front for the ash-pit, iire,v
door, and opening to the flue-space, respectively, and the cold-air opening E at the rear. F represents thebottom, F1 the sides, and F2 the top walls, of an inside structure, also of brick, in which the fire-pot, smoke-lines, and some of the cold-air flues and chambers are arranged, the ends of said walls fitting closely against the end walls of the outside structure, so that they constitute the end walls of the inside structure also. .The said structure is considerably narrower than the interior width of the outer structure, so that a heating-space, G, is provided between the walls F1 and the side walls of A. His the fire-chamber, from which the smoke-dues I extend over the wall K to the space L behind, from which two ues, M, extend back to the front to the space N, from which there are three ilues extending back to the space P, from which the smoke escapes through the top. to smoke-pipe Q, and wherein a damper, R, is arranged to regulate the discharge, 'said damper-being operated by the rod R extending through to the front. The cold air enters to the spaces U below the wall V, and spreads laterally through the dividing walls to the spaces G, where it is checked against rising immediately upward by the ribs W, and caused to move backward along the side walls F to Y cut off by the long ribs a., extending the whole length of the side walls, to divert the air to the lateral passages b, through which it goes to the long central longitudinal heating-chamber d, from which it escapes tothe spaces Gr again, above the ribs a, and thence passes to the space e at the top, from which to be conducted away through the hot-air pipes f. The heating-chamber dis arranged between the two smoke-nues M, and the lateral passages b are between said fiues and the flues I and the top wall J of the furnace. The upper lateral passages e are between said lues and the top ilues O. A1 represents a waterjtrough, extending through the outside wall into one of the upper lateral passages e, for
generating vapor to mix with the heated air in it, so arranged as to allow the water which is poured in at the outer end to flow through, and will prevent the escape of vapor. The fire-hole walls may be made of fire-brick if desirable, but may be of common brick;l but when so made they will be lined with sheetiron. The damper A2, for the cold-air inletpassages E, is hung from a shaft, B', pivoted on the end wall of the outer structure, and having a ratchet-wheel, C2, which, being held by a pawl, D2, provides an easy way of adjusting it.
Having thus described my invention, I claim as new and desire to secure by Letters Patent In the improved furnace herein described, the arrangement of the cold-air passage E, passage X, chambers Y Y Y', passages Z Z, spaces G, and dividing ribs, the passages b b, central longitudinal heating-chambers d, and the spaces e e arranged with the respective combustion chambersA or passages, all as two combustionpassages to reach the discharge-openings, as specied.
JOHNSTON MEALEY.
