HEATER.

. mode in Which I have contemplated apply- .ing that principle, so as to distinguish it from other inventions.

. My invention has reference broadly to 1A :means for carryn'ig out a method for fulfilling with a minimum loss of thermal units,

the operation required in the transfer 'of heat from one aO'ent to another. C

.'lo., illustrate the application of .the

. niethod,jb`oth preferred and modified structural combinations have been represented in the drawings. As a specitic exeniplification ot' these combinations, and for the purpose ot' .insuring a sufficientlyintelligent con sideratic'n' of .the novelty of the inventive conception, more `particular reference is made to a water heater.

The said invention. consists of means which are hereinafter fully described and particularly pointed out in the claims The annexecbdraivingsand the following description set forth. in detail certain means embodyingmy invention, the disclosed means, however, constituting asr al.- ready intimated, only some of Variousixnechanical toi-ms in which the principle of my invention may be applied.

Considering first the structure shown in Fig. l, it` will be noted that it comprisesan upright inclosing casing A, having a horizontal closed partit-ion a, dividing it into Specification of Letters Patent.

two divisions, a? and a8. 'Each of thes divi#V sions is provided near the top thereof with an outlet, a4 and o'rlrespectivcly, each coinniunicating with the chimney a. A pair or' gas'burners B and b', ofaiiy approved type, are disposed atpditterentheights within the casing, andas shown respectively near the bottom of the two divisions. a2 and a3. The upper of these burners, for e. purpose presently apparent, .is preferably, ,though not necessarily,- ot smaller capacity. i

A cold Water inlet pipe C connects with one side of the casing, andentersV at ,two points through the medium of a suitable T 'e and 90 elbow c2, and a correspondinghOt\W.ater outlet pipe D connects Withthe opposite `sideof@l the heater through the ine- Communicating with the inletTiStlieapy.

mary hot Water coil E. This, a.s shown, com

prises three horizontal*pipe-lengths connected by the return bends e and e2, and outside the easing with the elbow Zl The proximity of the lowerniost coil E- t' the rimary burner B, and the length of this coil? should be such that the Water will be raised Vto the desired temperature during its passage 'therethro'ugh. A second coil F is disposed above` the coil E, .and connects with the cold Water inlet through the medium of the elbow c. This coil is preferably ofrester length, comprising, vfor example,

ve horizontal i pipe lengths suitably connected by the return bends f', f2, f3 and f", This coil constitutes, ni accordance. with my conception, the Warm Water coil Wherebythe cold Water entering it. may be vsub-heated by the resid-f4 ual heat of the primary burner B prior to J its exit through the outlet a", leaving the chimney. The upper pipe length of-thexcoil F extends without the casing, and communicates through the medium of two elbows with the inlet of a third coil G, which-is dis:

posed over the upper burner b; This coil may be of relatively smaller length, owing to the fact that-the Water entering it has Abeen somewhat warmed, and as shown comprises merely two pipe' lengths4 connected by the return' bend g', the upper yof which passes out of the casing to connect with the hot water pipe D through the medium of the Td?. It should now tbe noted that Wasted, so that that which does-issue forth `through `the employment of this system of" through the outlet a4 is reduced to a temperature considerably below that of the hot water passing through the pipe D. Con.

a measnrably reduced loss of the heat car-` 'v ried by the particular heating agent.

The modification represented in Fig. 2 is merely one of simplification, and specifically through the omission of 'the Apartition a, whereby the gases of combustion from both of the burners may pass into the chimney through the single opening a5.

The modification to which Figs. 3 and l relate, includes as a means for heating the upper hot water coil, a by-pass construction as a substitute for the upper burner construction. To"this end, this form is provided with an angular partition p', best seen in Fig. 4. The horizontal portion of this partitioneXtendsI completely across the casing, as clearly shown in Fi 3, but is spaced'so'me distance from the ront thereof, as in turn best seen in Fig. 4, and at that point the depending portion of the partition is positioned. Another horizontal partition member p2 is secured to the front of the casing somewhat above the horizontal por- -tion of the `partition Z9', as clearly appearing in. Fig. 4., This partition serves the obvious function a kbaffle-plate whereby the gases of combustion rising in the by-pass B P are turned rearwardly in order to more effectually envelop the coil G. Figs. 3 and 4, it will be noted, represent a double series of coils, either series of which, ho ever, corresponds precisely as concerns is operative position, with that shown', inlfFigs. Ilwand uring the operation of heater -constructed in accordance with this b -pass modication, the gases of combustion from the primary burner B will simultaneously rise in the lower division a2 ot' the casing, and in the by-pass B. P. The warm water coils F are sub-heated an identical manner by the gases having theirexit through the outlet a?, whereas the water inthe upper hot water coils G is raised to the desired temperature by the gases of combustion .risingl through the by-pass B P, as will be readily understood. f A

The construction of the modified heater shown in Figs. 5 and 6 is designed to have its upper hot water coil heated through the medium of gases of combustion rising in a by-pass very similar to that disclosed in connection with the two figures considered in the previous paragraph.V The casing in this form I have designated by the referlocated above th ence letter H, the horizontal partition as h', and the two outlets leading to the chimney as la* and h5 modification have, however, a somewhat different construction, being fiat and of a width butA slightly less than that` of the width of the heater. The lower hot water coil, intermediary warm water coil and upper hot water'coil, have been designated respectively bythe reference characters K, L, M. The arrangement of the coilsis furthermore such that the intermediary inclined portions are alternately spaced from the front and rear of the casing, in order that the rising gases of combustion may be caused' to take a sinuous course on their way to the chimney. This will be apparent from an inspection of Fig. 6. Otherwise the operation of a he'ater so constructed is identical with that de scribed in connection with Figs. 3 and l.

The final .modification represented in Figs. 7 and 8 embodies all the details of construe'- tion shown in Figs. 5 and 6, save the specitic by-pas's construction with its partitions. The manner of heating the several superimposed coils-corresponds to that disclosed in Fig. 2, and consists in the .employment of the primary and secondary burners B and b', positioned hot water coil K and the upper hot water coil M. The gases of combustion from these are designed to find their exit through the common outlet zf.
