This nozzle 5 extends inwardly of the upper or primary heating chamber A and between two baiile plates 6 and ‘I. The plates I and 1 are vertically spaced and, extend entirely across the chamber A with the upper plate 6 terminating a 15 distance inwardly from the rear end of the lower ‘ plate '1. These plates 6 and 1 are preferably of cast iron and are held in assembled position in any manner preferred. ' _ - Intel-posed between the side marginal portions 20 of the plates 6 and 1 are the series of longitudi~ naliy spaced ?re bricks 8 there being one of such tained in desired assembled relation. ' The invention consists in the details of con struction and in the combination and arrange 25 mentoi’ the several parts of my improved furnace series at each side. These ?re bricks, as herein disclosed, are rectangular in form and are dis posed transversely on an angle of approximately whereby certain important advantages are at thirty degrees although I do not wish to limit my tained and the device rendered simpler,‘ less ex pensive and otherwise more convenient and ad vantageous for as will be hereinafter more fully set forth. The novel features of my invention will herein self in this respect. At a point directly in ad vance of the nozzle 5 and at a point'beyond the longitudinal centers of the plates 6 and ‘I is ar ranged a ?re brick 9. This brick 9 is also rectan 30 gular in form with its flat faces at right angles after be de?nitely claimed, , In order that my invention may be the better to the longitudinal center of either of the plates 6 and 1. In advance of this brick 9 and at opposite sides same with reference to the accompanying draw of its transverse center are provided the addi 35 ings, wherein: tional ?re bricks Ill.

These bricks I, 9 and III also re taken through a furnace constructed in accord tain the heat thus further assuring the creation ance with another embodiment of my invention; and maintenance of an intense heat within the Figure 5 is a sectional view taken substantially chamber A. on the line 5-5 of Figure 4; ‘ The chamber A through its lower wall at its 50 Figure 6 is a vertical sectional view taken forward portion is in communication through the transversely through a furnace constructed in coupling II with the upper forward portion of accordance with a still further embodiment of my the lower or secondary heating chamber 3 and understood, I will now proceed to describe the invention. 55 a In the form of invention as illustrated in Fig the products of combustion are drawn down into and through this lower or secondary heating 2 2,117,924 chamber B by the draft created through the flue F. This ?ue F communicates with the lower por tion of the chamber 13 through the rear or back head l2 thereof. vides a further path of travel ‘for the products of combustion as drawn from the upper or pri mary heating chamber I’ whereby the air within . the casing or housing H’ is further heated. _ Interposed within the lower portion of the chamber B are the oppositely directed ba?ie plates l4 and IS, the upper plate [4 extending inwardly from the front head IQ of the chamber B while the lower plate l5 extends inwardly from the The embodiment of the invention as illustrated in Figure 6 is substantially the same as the ?rst embodiment except that the members I‘ and 2‘ are surrounded by the spaced jacket 21 providing a water space‘ 28. The supporting standards 8 10 rear head (2 at a point preferably immediately v dlrectly coact with this jacket 21. In this em 10 above the point of communication of the ?ue F bodiment of the invention a hot water furnace is with the chamber B. These ba?le plates l4 and provided or with equal facility vapor or other ?uid I5 cause the products of combustion to travel in may be heated.‘ a tortuous path through the secondary heating 15 chamber B thus assuring maximum of heating eiliciency. The members I and 2 are maintained in de sired assembled relation by the standards 8 ar ranged fore and aft of the members I and 2 at opposite sides thereof. Each of these standards S at suitable positions thereon are disposed on out bows, as at ll, of such radii to snugly receive the adjacent portions of the members I and 2. Each pair of standards S are held in clamping en gagement upon the members I and 2 by the in terposed stay bolts l8. In Figures 1, 2 and 3 I illustrate the members I and 2 as arranged within an enclosing casing or‘~housing H, certain of the walls of which being provided in their lower portions with air inlet openings I9 while the upper portion of this cas ing or housing H is formed, as at 20, to allow for the desired carrying off of the air heated within From the foregoing description it is thought to be obvious that a furnace constructed in accord ance with my invention is particularly well adapt ed for use by reason of the convenience and fa cility with which it may be assembled and oper 15 ated, and itwill also be obvious that my invention is susceptible of some change and modi?cation without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise ar rangement and formation of the several parts herein shown in carrying out my invention in 25 practice except as hereinafter claimed. I claim:— > I A heating unit comprising two vertically spaced heating chambers in communication with each other, a'discharge ?ue connected to the lower 30 portion of the bottom chambena pair of hori zontally disposed vertically spaced apart plates in the upper chamber extending across the width trated in Figures 4 and 5 is substantially the of said chamber, said plates having their front ends abutting against the front wall of the upper 35 chamber and their rear or inner ends spaced in same as that hereinbefore set forth with respect wardly from the rear wall of the upper chamber, to the ?rst form of my. invention except that the a plurality of vertically disposed ba?le members positioned adjacent the side edges of said plates and extending inwardly thereof in parallel planes the casing or housing H. ' The embodiment of the invention as in - upper member I' at its forward portionand to one side of ‘its vertical center has in communica tion therewith, as at 2|, an end portion of aleg 23 of a substantially U-shaped conduit 24.
