T a/ZZ whom it marifoon/007%:

Be it known that we, JAMES DAMEY and WILLIAM H. CORK, citizens of -the United States, residing at Chicago, in thecounty of Cook and State of Illinois, have invented a new and useful Improvement inVHeaters, of which the following is a specification.

Our invention relates particularly to heaters which are provided with a hot-water orV struction there are employed a heating-cir-- cuit wherein the heating iiuid is maintained 2o at a given temperature, a hotWater-supply circuit wherein water is ordinarily maintained at a higher temperature, and a separate low-level heating-circuit available for heating at low levels. Our invention is illustrated in its preferred form in the accompanying drawings, in which- Figure l is a central vertical section parallel to the sides of theh'eater, the section being taken as indicated at line 1 of Fig. 2; Figs. 2 and 3, transverse sections taken asindicated at the correspondinglines of Fig. 1; Fig. 4, a section similarto Fig.'1, butshowing the inner wall of the outer flue of the heater in elevation; Figs. 5, 6, 7,' 8, 9, and 10, sections on a reduced scale and taken as indicated at the corresponding lines of Fig. 2; Fig.'11, a section, on a reduced scale, taken as indicated at line 11 of Fig. 1; Fig. 12, a broken -view 4o showing the base and grates of the heater viewed as indicated by the arrow at line 12 of Fig. 2', and Fig. 13 an enlarged broken horizontal section showing -the connection between the rear section and a side section of the outer wall of the outer ue.

The preferred construction is as follows:Vv 1 represents the heater base, Fig. 12, upon which are mounted a circular grate 2 and a coacting grate 3, suitably concaved at its front 5o portion to serve the grate 2; 4, the outer wall or casing of the heater, which constitutes also the outer'wal-l of` the outer flue 5 and which has a removable rear section 6; 7, a fuel-magazine -whi'ch'depends from the upper portion of Vche heater and is located above the center of the grate 2, said magazine having, Fig. 9, an inner wall 8,`an outer Wall 9,.peripheral vertically disposed water -legs l10, radially-arranged 'hollow' stubs or headed pipes 11 at the front'portion of-the magazine, and a lower 6o central chamber` 12, Fig. 1, separated from Vthe upper portion of. the chambered magazine vby a partition 13; 14, Fig. 11, an outer waterchamber comprising two curved sections 15 and 16, meeting in a vertical plane .at the front portion of the-heater, and a iat rectangular rear section 17, meeting the sections 15 and -16 ina vertical plane at the rear portioneof the. heater; 18, Fig. 3, a steam vor hot-.water dome 'communicating with the 7o water-chamber 1'4 through pipes 19, Figs. 3 and G;,20, passages or communications between the dome18and the adjacent upper ends of the water-,legs 10; 21, Figs. 2 and 8, due-passages through the two side water-legs 10, at the upper Vportion thereof; 22, a baftleplate which covers the rear portion of the outer or return flue 5, as illustrated in Figs. 4`and 7, saidfb'affle-plate ending in downwardly-extending partitions 23, which divide 8o the outer due vertically, Fig..9; 24, an upward extension for the magazine 7, formed in the dome 18, as .illustrated in Figs. 1 and 2; 25, a flue leading from the upper portion of the magazine extension or chamber 24 through 85 the dome'18 to the smolIe-stackv26 at the rear `ofthe hea`ter,"a damper`27 being interposed between t'l1elue-25 and said smoke-stack;

Y 28, a branchpip'e orlue connecting the smokestack26 'with thezflue 5 beneath the baiie- 9o plate 22, said branch pipe being equipped with a damper 29; 30, a cold-water or return pipe having branches 3land 32, the latter in'turn having branches 33 and 34, the branches`31 Yand 34 serving to supply water to the outer 9 5 chamber 14 and the branch'33'servin'g tosupply water to the chambered reservoir 7 above the partition 13; 35, a pipe through which the circuit of the chamber 14 is supplied, said pipe usually having connection with a reser roe voir (not shown) and a valve/36 being providedthrough which water is admitted ytoreplenish the water of the circuit when desired; 37,a pipe comm unicating with the branch pipe 31 and with the steam-.dome 18 and equipped With'a sight-glass 3S and a pressuregage 39, said pipe being available when it is desired to employ the circuit ofthe chamber 14 as a steam-circuitg'40, a steam-chamber communicatingywith the dome y18 and provided in,- ternally,'Fig. 1, with a diaphragm 41, which serves to actuate a lever 42,connected through the medium 0f a rod 43 With a draft-regulating door 44 and connected alsothrough the medium of a rod 43a with a draft-check door 43"; 45, a hot-Water or steam pipe, as the case may be, having branch connections 46and 47 with the dome 18; 48, Figs. 1 and 4, a supply-pipe communicating with the chamber 49, formed in the backsection17 of the outer water-chamber 14, said chamber 49 being separated from the remainder of the back section by a partition 50; 51, an outlet or hot-wa .ter pipe for the chamber 49, the same being equipped with a valve 52; 53, a branch pipe connecting the chamber above thepartition 50 with the pipe 51 inside the valve 52, said pipe 53 being equipped with .a valve 54; 55, Figs. 3 and 7, a cold-Water or return pipe for the chamber 12;v 56, a hot-Water or outgoing pipe for the chamber 12, said pipe being connected through .the medium of-a branch pipe 57, Fig. l1, equipped with a valve 58, with the dome 18; 59, Fig. 1, a fuelfchute leading to the chamber 24; GO, Figs. 1 and 11, an inner tire-pot removably connected with the lower end of the fuel-magazine, and 51 a removable chute leading through the outer Water-chamber 14 to said removable fire-pot.

The branch pipes 3l and 34 arenequipped with valves 62 and 63, respectively, and the branch pipe 33 is equipped with a valve 64. The back section 17 of the outer Water-.chamber 14 is equipped on its inner side with headed pipes or hollow'stubs 65, as shown in. Figs. 3 and 7. These pipes are arranged on opposite sides of the rear Water-leg 10 and are of varying lengths'in order to conform to the shape of the inner water-chamber, as shown in Fig. S. Fig. 1 illustrates the manner in which the grate 2 is pivoted at its center in order to oscillate in a horizontal plane. Fig. 12 illustrates the manner in which the grate 3 is journaled to permit it to be swung on a horizontal shaft 66. The manner in which the sections 15, 16, and 17 of the outer waterchamber 14 are detachablyjoined together is clearly shown in Fig. 11, Where are shown lugs on the several sections and bolts connecting said lugs. The base 1 is shown in Fig. 12 to be provided near its periphery on its upper surface with danges l and 1b, inside the former of which the lower end of the outer water-chamber 14 is located and outside the casing 4is,made removable is clearly shown ,in.Fig.1 13, Where the rear sectionG is shown ,equipped with angle-irons 67, which are detachablyjoined byscrews 68 to the adjacent portions of the sides of the casing. As shown in several of the figures, the lever `42 is pivoted at 69 and is'provided with an adjustable Weight 70,through which the action of the -lever lis controlled. v

From the foregoingdescription the manner of operation will be readily understood. Chamber 12 at the base of the'fuel-magazine being located near the hottest portion of the lire readily serves, though of a small size, to supply` as much highly-heated water as is usually desired Yfrom ay heater of this kind. The lremaining Water-chambers-of the heater, with the exception ofl the chamber 49 at the lower portion ot' the back section 17 of the outer Water-chamber, are all connected and Serve to supply Water at the desired temperature to the radiators. The Water-chamber 49 may serve t0 supply Water at a comparatively low level where required,las for greenhouse purpose's.` y

During those seasons of the year when little or n0. heat is required for the heating-circuit and itis still desired to have a hot-,Water supply for the baths and lavatories the inner fire-pot and the chute 61 may be putin place, as illustrated in Fig. 1. -Thedamper be-V ing left open and ,the damper 29 closed, as illustrated in. Fig., 1, the draft is -directly through the fuel-magazine, and the re is confined to a lsmall portion of the grate, the fuel being charged in through the chute 61.- During `such I Yuse yot' the lheater the outer cham bers and Walls of the heater serve to prevent radiation of theheat in tothe room Where the heater islocated.

For Winter service the fire-.pot 60 and'chute 61 are removed, the damper 27 closed, and the damper 29 opened. The chamber 49 at'the base of the back section 17 of the outer Waterchamber 14j mayl or may notv be connected IOC IIO

With the general heating-circuit. Assuming f the valve 54 to be closed and the valve 52 to be open, the low-level circuit would be disconnected from, the kmain heating-circuit and Water Wouldiiow through the low-level circuit, as indicated bythe arrows in Fig. 1.

suggested the fuel-magazine is kept charged through the chute 59. ward between the inner-water-,chamber and the outerWater-chamberamong the Water-legs 10 and the horizontal water-pipesll and 65 till the dome 18 kis encountered, and thence downwardthrough the .front'portion of the flue 5, past the lower ends ofthe vertical partitions 23, and upwardlythrough the rear portion of the flue 5.to the branch pipe 28. Such products of combustion as pass npwardly at the rear portion of the heater and The draftis then up- A p encounter the dome are forced to pass forwardly throughl the flues 21 and available' spaces between the upper portions of the side water-legs 10 and adjacent portions of the outer `water-chamber 14, after which they pass downwardly outside the outer wall of the outer water-chamber 14 and through the front portion of the iiue 5 till 'they pass the lower ends of the partitions 23, whence they pass to the'branch pipe 28. The draft-door 44 and the check-door 43", being connected with opposite ends of the lever 42, move in opposite directions, so that when the draft is opened the check is closed,'and vice versa. In the first adjustment the draft-door will be left open as much as is desired and the weight '70 so located as to permit the lever to o'perate only when a certain degree of heat isy reached. When the diaphragm 41 is forced upwardly by' steam-pressure, the result is to raise the check-door 45b and lower the draftdoor. The heater is properly arranged and equipped to permit the main heating-circuit to be operated as a steam-circuit instead of a hot-water circuit. Such a conversion can be accomplished merely by supplying less water to the boiler and maintaining the water within required limits by reference to the watergage 38.
