COMBINATION FIREPLACE ANI)` IIE-ATER;
` Application sied kMay 5,
My invention relates to lire-place heaters and, among other objects, `aims to provide an improved apparatusA to conserve some of the heat of the waste gases.
In the accompanying drawings wherein I have shown one illustrative example of my invention,
Figure 1 is a front elevation of a` Iireplace embodying my improvements; f
Figure 2 is a sectional view `taken on the Figures 3 and 4 are sectional views ltaken on the linesB-S and 4-4frespectivelyof Ii`igure-2; andv Y Figure 5 is a sectional view taken on' the line .5 5 'of Figure '3, the grate being omitted.
. Referring specifically to the drawings, I have shown the preferred embodiment of my invention ,in the form of an open fireplace heater adaptedto be placed in a room and connected to an ordinary chimney tlue.
- I'Ierein, I have shown an outer casing 10 made oit" sheet metal and being substantially oblong in cross section above the tire-place.`
rlhe lower portions at the front andrear are open and an open brick hre-place 11 of suitable size and shape is built within it. (See Figures 2, Sand 5.) Herein. thel back wall of the lire-place is narrower than the casing', and the side walls converge rearwardlyto provide air circulating tlues 12 between the-no and the sidewalls of thecasing.
In the present example, I have shown a basket grate 13 for burning coal or other tuel. rIhe casing,
sents a vertical. Ilue across which I have provided a bank of upwardly and forwardly inf clined hot air-tubes 14, eachconnected to a stepped portion 15 ofthe front wall ofthe v lation as shown in Figure 11. These tubes are shown as connected to a rear vplate 16 which forms the rear wall of the'liue, and has stepped portions similar to those in the front wall.
At the upper end of the casing, rearwardly of the vertical flue, I provide a smoke box j 17, havingtransverse partition walls 18 (see Figure 4), the ycompartment space between the portions leading directly to an'outletl flue 19 connected to a chimney.
Further to utilizev the wastegases to heat the air prior to entering the tubes 14, I have,v
above the grate 13, pre-V nhold this plate in adjusted position.
1927. Serial N'o..189,118.
shown a lower smoke-box 20 'resting onv the ltop oi: the rear wall of th'efiire-place, and a series of vertical smoke tubes 21 are con-i nected to the upper and lower smoke-boxes.
As shown in Figure 4, some of the tubes 21y I f are connected tothe twoside compartments of., the upper smoke-box, and some are connected to the central compartment.y
lTo direct the waste. gases-,through these tubes and. smoke-boxes, or to permit themA have shown f to'r pass directly to the chimney, a damper -22 controlling the1 central 'compartment ofthe upper smoke-box. Herein, I provide an operating rod or handle 23 projecting through the 'trontjwall of thecasing` I/Vhen vthe damper isclosed, as shown in Figure 2.the vwaste gasesenter the side comdownwardly through the tubes 21 connected thereto into the lower smoke-box, thence, upwardly through the tubesconnected lto the central vcompartment and then out through the outlet flue 19. p c
To permit fresh air to circulate around )artments` of the upper smoke-box, passA the smoke tubes 21 and pass'throu'gh the het air tubes 14, I provide air inlet openings 24 at` the sides of the casing adjacent to :the
bottom, and other' openings 25 labove 'the g 'lower smoke-box 20. The aiigas it is heated,
ypasses upwardly Into the room, and 1s AeX-` posed to the most intense heat as it passes throughl the upwardly inclined bank of tubes.
To close the trentk of the fire-'place andv increase the vdraft through the grate, I lprovide a sliding damper or plate v2e which is adapted to `be pulled down to the top of the grate. This is particularly desirable fory starting` acoal Iire. 1 Any suitable stop means l(not'shown) mayl be employed to It is preferablymade to slide upwardly behind theui'ront` wall of the casing 10 below. the lowermost row of hot air tubes-10.
In some instances, it may be desirable to connect the-fluey from lmy fire-place directly to an old fire-place opening. j Simply to illustrate how this maybe done, I have shown an outlet 27 (see Figure 2) connected to the lower smoke-box. If such an outletA is used, the'upper one 19 is closed.`
Obviously the presentinvention is not re-i stricted Yto the particular embodiment there- A,
of herein shownfand described. Moreover,
it `is not indispensablel that all the features ofthe invention beflused conjointly, since' they may be employed advantageously in various combinations and subcoinbinatione.
lVhat I claim is: l
1. A heater of the yclass described. cornprising, in combination; a lire-place; a casing therefor having` front, rear, and intermediate walls providing a vertical sinoke Vllue and an air chamber; a series of upwardly and forwardly inclined hot air tubeeI arranged across said vflue between tbe trout and' intermediate walls to deliver hot air into the rooing a smoke-box adjacent at the top of the c i g in the rear of Said flue and havingI a series of compartments therein; a second smoke-box behind said flue and above the fireplace; a plurality of vertical lire tubes connecting' said smoke'- boxes and so arranged with relation to the compartments in the top smoke box as to pei-init the sinolre to pass downardly into some of the tubes inthe bottom smoke-box and upwardly through others oft the 'tubes into one oit the compartments to be discharged into the ehhnne 1.
2. A heater of the class described coinprising, in' combination;l a lire-place; a casing therefor providing a substantially vertical flue; a bank of upwardly and for-A wardly inclined hot air tubes extending,l across. the flue and arranged in horizontal rows with the tubes in adjacent rows in stag gered relation; a smoke-box at the top of the casing having series of compartments therein; a second Smoke-box below the top slnolizebof; arranged at the rear of said flue and projecting partly inwardly above the lireA` place; a series of vertical sniolre tubes conricci-ing said smoke-boxes and so arranged ae tol permitl the .eniolre to'pass downwardly ture.
