COAL BURNER.

Application led January 8, 1923. Serial No. 611,421.

To L7/Z whom t may concern:

Be it known that we, JAMES CHARLES ORB and CHARLES Twnnnin CLUrr, both of the city of Winnipeg, in the Province of Manitoba, Canada, have inventedY certain new and useful 4Improvements in Coal Burners7 of which the following is the speciication.

The invention relates to improvements in coal burners and an object of the invention is to provide a device for insertion in the fire pot of a furnace and which is particularlyV constructed for use in the burning of soft coal in they furnace, the device being constructed to supply air for combustion purposes and to separate the fire pot into two lire compartments, such latter permitting of the alternate firing of the coal in opposite sides of the fire pot.

A further object is to construct the appliance such that it can be readily inserted in the furnace through the tire door and such that it is entirely supported by the grate bars.

A. further object is to construct the apv `divisionalmember lwhich passes in al direcpliance in a simple,V durable and practical manner and such that/it can be produced l and installed at a comparatively small cost.

With the above` more important objects 'in view the invention consists essentially in the arrangement and construction of parts hereinafter more particularly described and later pointed out in the appended claims reference bein'g'had tothe accompanying drawing in which:

Fig. 1 is a perspective view of the device. 1

Fig. 2 is a face view divider.

Fig. 3 is a horizontal sectional view through the hollow post, the section passing` through the side channels.

ig. 4 is a vertical sectional view centrally through the appliance as it appears in the fire pot, the divider being shown in side elevation.

In the drawing like characters ofireference indicate corresponding parts in the several figures.

In the burning of soft coal considerable care has to be exercised in order to get the best results ,from the same and also to prevent explosions in the furnace. We have ofthe double winged i devised the burner herein described for insertion in the customary fire pot 1 of the furnace, the burner being located centrally lof the furnace and having the baselthere'of resting on thegrate barsV 2.1 Thelburner presents a hollow body or post 3 having a centrally disposed vneck 4 which ares out and terminates at the bottom in an enlarged base 5 and has the upper end terminating in a hollow ball or sphere 6. The ball at spaced pairs of vertical flanges 8 and 9- cast integrally therewith and forming vertical channels or guides 110 and 11, the lower ends of the guides being closed by the flaring portion ofthe base."v y Associated 'with the' post we provide a is adapted to seat on the top of the ball or sphere and the inner edges of the wings are `'designed to, slidably enter the guides "or channels 10 and 11 of the post. By forming thisr divisional member lin this way one can first 'insert the post through the ire door" and locate it properly on the grate bars, then he can insert the divisional member and place it in position on the post and in this connection it is advisable to have the divisional member passing in a direction from the front to the back of the furnace as this makes it a very easy matter to fire the coal used to either side of the fire pot. Y

When the divider is in place within the furnace the ball is above the coal level and the lower edges of the wings are above the grate bars, whilst the ends thereof are entirely clear of the inner side of the fire pot.-

The

cient air, provided through the openings 7,r

to provide a combustible mixture which ignites. This prevents any possibility of eX- plosion.

Gradually the coal in the compartment will come to a nice even glow and when it has burnt down one throws fresh coal into the other side of the fire pot. The gases of this fresh coal are distilled out by the heat of the lire in the other` compartment and, mixing with the air, become ignited in the combustion chamber.

The operation of alternately firing in opposite sides of the fire pot is .continued each time new coal is placed in the furnace.

`We might also mention that theburner is made of cast iron and has fairly thick walls so that it becomes very hot and accordingly assists in distilling out the gas and also in heating, to a high temperature, the air supplied through the grate bars and out the openings 7 to the combustion chamber.,

lVhat we claim as our invention is:

l. A coal burner for insertion in the fire pot of a furnace,-comprising a hollow post having the base thereof resting on the furnace graterbars and having the upper end thereof closed and provided with a plurality of'air outlet openings communicating with the combustion chamber, and a removable divisional member carried entirely bythe y upper end of the post and extending across the fire pot in an elevated position above the grate bars and dividing the fire pot into two ring compartments. y

2. A coal burner for insertion in the ire pot ofa furnace, comprisi-nga Vhollow post positioned centrally of the fire pot and having the lower end thereof resting on the grate bars andthe upper end communicating with the combustion chamber of the fur- .firing compartments.

3. fr coal burner for insertion in the fire pot of a furnace, comprising a hollow post positionedcentrally of the fire pot and having the base thereof resting on the grate bars and the upper end thereof terminating in a perforated ball, an elevated divisional inember crossing the fire pot and dividing the same into two firing compartments and having the lower edge thereof clear of the grate bars, said divisional member being remmable and hung from the ball and being prevented from rota-tion around the post.

il. A coal burner for insertion in the iire pot of a furnace, comprising a hollow post positioned centrally of the lire pot and having the lower end enlarged and resting on the grate bars and the upperA end closed and perforated, and diametrically opposed pairs of vertically extending spaced Aflanges provided on the post and forming vert-ical giudeways at the opposite sides thereof.

5. The combination with a hollow perforated post for insertion within the ire pot of a furnace, said post being provided with diametrically opposing vertically 'extending guides, of a divisional member insertible within the fire Ypot and elevated above the grate bars thereof and dividing the same into two firing compartments and in the form of a pair of wings having their inner edges adapted to be receivedwithin the guides, the-said wings being connected by a strap passing overvthe upper end of the post and supporting the said divisional member. y 5 y Signed at Winnipeg, this 8th day of December, 1922.
