Application led December 22, 1924.

rlhis invention relates to heaters adapted to be used more particularly for burning culm and other fine coal although it 'is equally useful in burning coarser coal if desired.

The main object is to support the fire box in the combustion chamber in such manner as to provide anextra supply of fresh heated air to the surface of the fuel at various levcls for the purpose of increasing the combustion of the fuel and also for burning practically all of the gases released from the fuel and thereby to reduce to a minimum the smoke content of the escaping products f of combustion and to greatly increase the temperature of the heat developed from a given quantity of fuel. i

In other words, I have sought to produce a more economic combustion of the solid fuel and the gases generated therefrom so as to increase. the resultant heat `and reduce the smoke content of the escaping products.

One of the sp-ecilic objects is to support the lire box in the combustion chamber in such manner as to provide vertical air passage between the walls of the fire box and combustion chamber from the ash pit to the top of the fire box and also to provide the walls of the fire box with openings therethrough the major portion of its length or height so that fresh air may pass from the space around the fire box through the openings to thefuel at varying levels and also across the top of the fire box in case the lat? ter should be filled with fue] so as to heat the. air in tr sit to the fuel for increasing combustion oit the fuel and gases.

Another object is to make the lire box in sections and to provide suitable means where# by they may be supported and locked in operative position upon an underlying supporting ring carrying the grates which form the bottom of the fire box.

Other objects and uses relating to specific part-s of the device will be brought out in the followingdescription.

Figure 8 is a horizontal sectional view taken in the plane of line 3 3, Figure 2.

Figure t is a perspective View of a de tached gratesupporting ring.

Figure 5 is a perspective View of one of the detached fire box sections.

As illustrated this heater comprises a shell 1 forming a combustion chamber Q in which is placed a lire box 3- haying a supporting ring l resting upon suitable lugs 5 of the ash box 6 said ring being provided with means for supporting a series of grate bars 7- which are connectedto each other by gears S for simultaneous rocking movement, the intermediate grate barsbeing provided withy extensions 9- through the front side of the ash box for manual operation by a suitable shaker, not shown.

rihe lire box 3 is mounted within the combustion chamber 2 ,and, aside from thering l is composed of a series of similar upright segments 3 arranged edge to edge in close juxtaposition around a common, vertical axis and having the lower ends of'their adjacent edges provided with downwardly extending lugs l0 which are seated'in suitable openings ll in the ring 4 to hold the segments in fixed rclation yto the ring against relative lateral or c ircui'nferential movement and at the Asaine time permitting said vsections'to be withdrawn upwardly from the ringer replaced downwardly into `,operativeV connection therewith without disturbing the ring frolu Yits normal position.

rilhe object in making the main body of the fire vbox in sections is to permit them to be more easily placed in operative position upoir the grate ring or removedtherefrom through the fuel door of the heater. The supporting lugs 5 for the grate ring 4 are arranged in circumferentially spaced relation tov permit thefree passage of air from the ash box 6 upwardly between them.

The marginal edge of the ring lt is" provided with a series of vertical openings 1EZ therethrough communicating with the spaces between the lugs 5 to permit the passage of air therethrough from the ash box upwardly between theY walls of the
