Application filed Earch 3.1 1915 Serial Ho. 13 67%.

T all whom it may concern j Be it known that I, Emerson 18. Boston), a citizen of the United States, and resident of La Crosse, in the county of Crosse, and in the State of Wisconsin, have invented a certain new and useful Improvement in Fuel-Burning Apparatus, and do hereby declare that the following is a full, clear, and exact description thereof.

The object of my invention is to provide means for fuel. burning apparatus (by which I include stoves, furnaces and other heat producing devices, Whatever their construction and use may be) whereby great economy in the fuel used may be secured by the iiti zation to a high degree of all of the coinhnstible elements in the fuel for the generation of heat, and besides this general and very important object, I have in view the pr0- duction of a construction which will he sins pie and inexpensive, and have other advantages-which will be evident to those skilled in the art when they understand from the further disclosure herein the nature of my invention.

In the. accompanying drawings Figure 1 is, a vertical section of enough of an ordinary water heater to illustrate one embodiment, or adaptation of my invention; Fig. 2 a front elevation thereof; Fig. 3 a front end elevation of certain of the parts; Fig. 1 a detail view in perspective of the form of battle plate employed in the structure shown in Fig. 1.

Referring to the drawings in connection with the detailed description of the construction illustrated therein l0 designates a Water boiler adapted for burning coal and provided with a fuel-supporting grate and a hopper, or feed pouch 12 projecting forwardly from the front of the coiier its outer end provided with a i iinejed door 13. Within the feed pouch, and forming in effect an elevated false bottom the; shut c5 14: consisting of a plate that from the outer end of the pouch a cline downward and forward, and. i ner end has a vertical flange 15 that $3. down to bottom of the po c 4 its inner end and forms in elm-c a vsrti extension of the fire pot, creases the fuel hold pet, The outer ed e if i will" or diaphragm o a cement to the inner edges of the door 18, s to form i the door a chamber 17, 0 make the door 13 a hollow body, the te 16 extending not quite to the bottom of the door, so a passage 18 from within door into the pouch below the shot all 14-, provided. The door 1?, preferably near i s top, is provided with one, or more air holes 19 so that air from the outside may pass into the chamber 1'2 in the door and from. the member 17 through the pas sage 18 into the space within the pouch beneath the shut oh 14. Within the space be tween the shut oil? fi land pouch, is battle plate 20 which extends from the door 13 (downward and inward at. a h' i line, and at its rear end has a do range 21 spaced in fr u t flange 15 of the shut 0%, reaching downward only m5 part 0" the ay so as to provide an opening 2 leading from. the space 23 below the baffle plate 20 into the vertical space 24 between the shut off flange 15 and the battle flange 21,

and thence into the space 25 between the battle plate 20 and the horizontally extending portion of the shut off lie, above the same. it will thus be seen that air entering the hole or holes 39 in the door will pass downward through the chamber 1? therein in contact with the heated hack wall 16 of the doc i thence backward through the passage L it into the vertically extending passage 2%, a S thence, forward through the passage p the narrow space between front edge of the shut off l i and the back all 16 of the into the ponch having in its circuitous with the heated surhid of t e air is i of lieatdome, or nee, Without v 1 Besicies this, cl eed l pouch, it coasts ediment to he which is secured by bolts 5.5

No bottom draft, that adrailit upward through the grate is required, because 01. the high degree of combustion "which I obtain by my means of preheating the air so that the layer of ashes below the plane designated by the letterA- in l 1 may be retained to check the draft from oelow.

Careful. and long conducted. tests of apparatuses embodying my invention have shown a verygreat saving; in fuel and the prod uction of a more even and steadier lire.

Having thus described my invention what I claim \is- 1.
