I A. H,- BARTLETT. 'Hot'Air Furnace.

HIIHII'HIIITI'IIIHIIIIIE OM d i IIHIIII HI'IHIIIII IIIIIIIIIIHl Hour-Am rnn'iwlicnl Specification of Letters Patentilllo. dated January 30,185.
To all whom it may concern Beit known,that.-I ABEL H. BARTLETT, of zKings Bridge, in tithe county of -Westchester and 1 State of New York, have invented certain new and useful Improvements in Hot-Air Furnaces; and I do herebyde: clare .thatthe following is a'full, clear, and exact description of the same, reference be ing had .to the annexed. drawings,- making a part ofthisspecification, in which Figure 1 is a front'view of my improved furnace. Fig. 2 isalso a front view ofditto, the casing or masonry nearest the eye being removed. Fig. 3 is aside view of.ditto, with the casing .or masonry nearest-the eye removed.. l
, Similar letters of reference indicate corresponding parts in the several figures.
.Toenable others ,skilled inthe-art to fully understand and construct my invention,.;I
will proceed to describeit.
A represents the casing or wall of masonry which surrounds the. furnace.
B is the fire chamber and JG isthe flue of the fire chamber which is of serpentine form and passes around flat horizontal chambers D which form the air heating chamber, the horizontal chambers D extending the width of the chamber or compartmentwhich forms the flue C both ends of the chambers D communicating with the space between the side plates (at) of the flue C and the masonry A as shown in Fig. 2. A suitable space is left between the chambers D to allow the flue C to be of the requisite size.
E is the back plate of the flue C or rather the upright portion of it a space being left between the plate E and masonry A said space being a continuation of the flue C and having a downward draft as will be hereafter explained.
G are plates which are connected alternately to the sides of the chambers D and the back plate E and masonry A at the front of the furnace see Fig. 3 for the purpose of causing the draft and heat from the fire chamber B to ascend in serpentine form and between the chambers D.
H H are openings at the upper part of the plate E and I is the smoke pipe which communicates with the lower part of the space between the plate E and masonry A as shown in Fig. 3.
J, Fig. 2, are plates which are connected alternately to the upper ends of the chambers D and the masonry A for the purpose tine form through the chambers D,-
.K, seeFig. 2,. is an opening; at the lower part ofthe masonry A, throughwhichthe cold air is admitted and Lis a ;pipe which communicates with one end most chamber D. i 1 o M is a damper at the lower part of the space between the plate and masonry A,
see Fig. 3;
of. causing the cold airto ascend in serpenof the u-pper- 1' ,Ifba. direct draft is required at fi rst in order that the fire may bemade quickly, the
damper'M is opened and the draftqis vdirect from the fire chamber B to thesmoke pipe I. When the damperM is closed the draft and heat passoupward through the flue-C in the direction=indicated by arrows lthe plates. G causing the. heat to pass upwardin serpentine form and horizontally between the-chambers D,.the heat passes over theuppermost chamber D and through the openings H and down the. space between the plate E and masonry;A into the pipe. I. I. The cold air meanwhile passes through thefopening K at the lower part of the masonry A I and ascends, passing in one end of the lower chamber D and out at the opposite end, and in consequence of the plates J ascends in serpentine form through the chambers D as indicated by the arrows 2, see Figs. 1 and 2 and the air in passing through each of the chambers D is subjected in broad thin layers to two broad heated surfaces of the flue C and when the air reaches the uppermost chamber D it passes in a perfectly heated state into the hot airvpipe L. Thus it will be seen that the 'air to be heated and the draft and heat from the fire chamber pass upward simultaneously in their respective passages and cross each other at right angles, the air in the chambers D being exposed to two heated surfaces of the flue C viz above and below and the horizontal portions of the flue C communicating heat to two surfaces of the chambers D, also above and below. This will be understood by referring to Fig. 8. The cold air therefore that enters the opening K passes over a great area of heating surface in passing upward to the pipe L.
The air heating chambers D are lined or are formed of two thicknesses of metal so as to leave a space (7)) around each chamber, see Fig. 3, and these spaces are connected by small horizontal pipes (0) to a vertical pipe (d) which communicates with the smoke pipe I. By this arrangement the air in passing through the chambers D is prevented from being impregnated with any deleterious gases that may escape through the pores of the iron of the flue C, for when it has passed through the inner thickness of metal into the spaces (b) it will instead of passing through the outer thickness, natu' surfaces, with the warmed fresh air, by
means of jacketed air spaces interposed between the surfaces exposed to the action of the fire and the air to be heated; nor yet, providing an escape pipe or passage to carry off the deleterious gases, but
I do claim as new and useful herein, and desire to secure by Letters Patent,
1. In combination with the arrangement herein specified of the serpentine fire and air fines or courses (C and D), providing each horizontal flue with an escape casing or jacket connected. by branch or otherwise (each horizontal casing) with a gas pipe or pipes uniting them with the chimney as shown and described; whereby a sure and quick escape is established for the deleterious gases at each horizontal flue travel, where the fire and air are retarded in taking their upward course and the air being heated consequently more exposed to absorption of deleterious gas; and whereby the stratum of air being heated, and traveling in succession the several horizontal flues (D), is protected from admixture with it of the deleterious gas throughout its entire exposure to heat in the furnace as represented and clescribed.
2. I claim the arrangement of the fire fiues (C) and air heating passages (D) herein specified and traversing at right angles to each other, when combined with division plates, or their equivalents, so arranged that the one stratum or current of air to be heated passes upward throughout the several hot air passages or channels in a serpentine course similar to, but at right angles with, the course given the flame, simultaneously passing upward in the fire flues (C), over, under and between the hot air passages or flues (D) as shown and described.
