1 Claim.

The invention relates to a furnace, and more especially to that type for the burning of bagasse or other similar fuels.

The primary object of the invention is the prevision of a furnace of this character, wherein the construction thereof is novel in form to materially increase the economical and rapid combustion of the fuel.

Another object of the invention is the provision of a furnace of this character, wherein the grate is novel in form and supported in a unique manner to assure perfect combustion and includes an adjustable hood forming an air duct which is ceni ,y trally located relative to the grate.

15 A furtner object of the invention is the provision of a furnace of this Character, wherein the fuel box is centrally located and surrounded by a hot air chamber which is extended below said box,

the Wall of the box being formed With superposed rows of air passages. for admitting heated air above the fuel and the utilization of the fuel gases for heating the air.

A still further object of the invention is the provision of a furnace of this Character, which is comparatively simple in its construction, thoroughly reliable and efficient in its purposes, durable, and inexpensive to manufacture and install.

With the above and other objects in view the invention consists in the features of construction,

r combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawing showing the preferred embodiment of the invention, and pointed out in the claim hereunto appended.

" In the accompanying drawingzfl Figure 1 is a Vertical sectional elevation of a furnace constructed in accordance with the invention.

Figure 2, is a sectional view taken approximately on the line 2-2 of Figure 1.

Similar reference characters indicate corresponding parts throughout the Vseveral views in the drawing.

Referring to the drawing in detail, the furnace 7 comprises a body A, having its side. walls 10, front wall 11, fire box 12 and bridge wall 13 confronting the latter at its rear preferably constructed from fire brick or any refractory materials as used for the ordinary type of furnace. This `cox 12 is preferably of oval formation, although it may be of any any other suitable shape with its fire chamber 14 centrally located in the furnace. The box 12 is built upon a solid foundation '15 provided with a central hot air compartment 16 of less area than the chamber 14 and is immediately beneath the latter. Surrounding the chamber 14, that is, its wall, is a Vertical hot air space 17, the latter being entirely about the box 12 excepting its front which is provided with an opening 18. The opening 18 in the front of the furnace is closed by a door 19 fitted to the front wall 11 in any suitable manner.

The front wall 11 on opposite sides of the door 19 for communication with the hot air space 17 are openings 20 Vnormally closed by closures 21 fitted to the wall 11 in any suitable manner.

The wall of the box 12 is provided with spaced superposed rows of horizontally disposed passages 22 establishing communication between the hot air space 17 and the chamber 14 above a small grate 23 arranged in the bottom of the said fire chamber 14.

The grate 23 is provided with a fianged circular central opening 24 in which is slidably positioned a perforated hood 25 forming a central air duct confronting the lower hot air compartment 16 and opening into the fire chamber. This hood 25 is supported on and pivotally connected at 26 to the inner end of a rocking lever 27 which is pivoted at 28 to the foundation 15 of the fire box 12. The lever 27 at its outer end which protrudes through slots 29 to the outside of the body A carries a balancing weight 30 and this lever 27 permts the raising and lowering of the hood 25 as will be clearly obvious.

Above the box 12 is formed in the body A a combustion chamber 31 closed at its top by a flooring 32 of a fuel hopper 33, the flooring being provided with a feed opening 34 centrally located relative to the fire chamber 14 to deliver fuel from the hopper centrally onto the grate 23 where the fuel is caused to pile about the hood 25 in cone formation, the height of such pile being regulated by adjustment of the hood 25 as will be apparent. It has been found by experience that bagasse burns best when fed from above the chamber 14 and allowed to pile up in the furnace in the form of a cone which latter is eifected in the fire chamber by the hood and the adjustment of the latter regulates the condition of draft When the material is being piled.

The heated air for the furnace may be obtainecl by utilizing the fuel gases for heating the air or the air may be heated by passing it through the bridge wall or through air ducts made over the top or through the side Wall of the fire chamber.

The important features of the invention reside in the use of the small grate 23 in the center of the furnace foundation, a central perforated hood 25 and the hot air chamber or compartment 16 below the box 12, as well as the other detail arrangements illustrated in the several views in the drawing.

The drawing illustrates the preferred embodiment of the invention so it is to be understood that changes, variations and modifications may be made Without departing from the spirit of the invention or sacrificing any of its advantages and as come within the scope of the appended claim.

What is claimed is:

A furnace of the kind described, comprising a body having a straight Vertical front wall and an opposed bridge wall, a substantially ovalshaped perforated fire box within the body and merging into the front wall, a solid foundation beneath the fire box and having a central hot air Chamber of considerably less size than the box and communicating with the latter, the box being spaced from the body to provide a hot air space about a major extent of said box, a grate for said box at the communication of the hot air Chamber therewith and having a center opening, a counter-balanced perforated inverted substantially cup shaped hood movable through the center opening into the grate, said body above the box constituting a combustion chamber having a downwardly tapered lower portion merging with the box and closing said hot air Chamber from said combustion chamber, and a top to the combustion chamber to provide a fuel floor and having a delivery opening to said combustion chamber.
