the 'ven w'o'l' o'e side 'befpi'e the balance w's done. To ciu'e this 'defe'c't is the object of myfinvention end I havefsoi've'djhe problem 'by teking `the`heate ge'se from 'the "fire t'o a point benje'th Tihe oven, di's'trihii't'ng `them over the between the t'p ef the even smd the top of with theltop of fbhe'pven. fl'ie 14, The fire-box' 'is eime'dfied with the isflues 14 and 15. The flues 12 and 14 are collectively equal in capacity to the flue 17, flue 15 or the flue 26. 'l This fiue 26 'leads from the port 21, With which it communicates, directly to the rear of the stove where it turns toward the fire-box side ,and communicates with a chimney flue 30.n rl`he fire-box side of this flue 26 has a port 27 adapted to efl'ect direct communication. between the top of the fireboxflue and thechimney. i

The front plate 31 of'the stove contains doors 32 and 33 Vfor the'oven and ashpit and a cleaning door 34 to allow access to the distribution fine' 16. A cleaning door 35 is al-o provided at the rearof the' stove in communication With a receptacle 86 having an inclined bottom 37 and into which'soot and particles of partially oonsumed fuel are precipitated.

The forward end of the fiue 26 is in-the fo'r'm of a'daniper 40, and a slidable damper 41 operated by a pull-red 4.2 controls the port 21 and a similar damper 43 operated by a. `pull-red 44. controls the port 27.

A 'damper-controlled port is located in the side wall 51 of the stove and'in a position slightly' below the g'rate, and the fireboir is;lin ed with fire-brick 52. J

The corner of the distribution flne 16 at eachside of the stove, (but not at the front andiback'), are cut elf by' plate's 55 andr respectirely to direct the flow froin the flue 17`to the fines 12 and 14.

'The space between the back-plate 6 of the oYen and -the'rear wall of the stove and surround'ng the fl'ue 17 and the `receptacle 36, vthe vspaceent offby the lates 55 and 56' and thespace between'the p ates 20 and 150 are. alll packed With asbestos or other heat insulating `material 'thus preventing radiatjion of 'any of the heat from the vfine 17 between Vits'en'dsjand enablin practically all the hot ga-see from the fire- 0x to be delive'red to the' distribution 'space 16.

In order to per-mit t e ready frequent Cleaning ofthe'si'de and top flues a scraper 190 o`f`inverted U-forrn and clasping the top and sides 'of the oven, has a pair ofrods 200 connected the'reto and projeeting through the front 32. .Bydrayvin 'this' seraper forward 'he'vs'ootandashesw ichj'collect'on the top and'sides 'oftheov'en are dislodged and pre cipitat'ed to'the 1distribution flne where they' may-'hej removed' by thev cleaning door 34'.

Then itf is l,desir'ed to have 'a direct draft upon thefirefrorn 'theohimney the damlper i 41 i 'closed andthe'daniper 43 opened w en the 'flow will he upjwardly throuxh the grate past the 4lnonthl', flue 17 to t through port' 2 7- andalong fljues 26 and 30 to the chimneandlwhen it is desii'ed to heatth oventhdamper '41 is opened and darhper f'cIoeedjfthus causing the draft to e space 28 distributin space 16, flues 12, 14 and 15, port 21 anc fiues 26 and 30 to the ehimney.

This particular arrangement of parts and flues seoures either a direct draft from the fire through the space beneath the stove top to the chimney or from the fire-box around the oven to the chimney and in the latter casethere is ractcally a uniform heating of all parts o the o'ven.

What' I clairn is as follows- 1 In a coolcing apparatus, the combination `with a heat generator and an oven; of a coniparatively large distributing ehamber beneath theoven; a 'downwardly extending flue atl the rearfi of 'the apparatus leading from the heat generator to the rearv of the heat distributing Chamber; a chimney connection; and flues leading from the distributing Chamber 'np each side of the oven to the chimney connection, substantially as described.
