UNITED STATES PATENT OFFICE.

ONTARIO, CANADA.
HEATER.
Application filed September 21, 1927, Serial No. 220,956, and in Canada November 15, 1926.
This invention relates to a heater of the type of self-feeding magazine heaters which are provided with a water cooled hopper. Our object is to devise a hopper which is of simple construction and which is adapted to allow manual stoking of the heater as well as the automatic feeding, or which may be easily removed so as to eliminate the self-feeder when it is desired to use fuel which is not adapted for use in the heater when the self-feeder is in position.
We attain our object by constructing the hopper with inclined sides and one inclined end of peculiar construction as herlnafter described, and by securing it to the heater bymeans of connections which are easily removable.
The construction of our device ishereinafter more fully described and illustrated in the accompanying drawings in which Fig. l is a front elevation of the heater, paatly broken away and partly in section; an
Fig. 2 is a longitudinal section of the heater, partly broken away.
In the drawings like numerals of reference indicate corresponding parts in the different figures. I
The heater consists of a casing 1 and a front water header 2 and a rear water header 2. At the top of the heater are steam and water drums 7 opening into the front and rear headers and pipes 4 also extend between and communicate with the headers. Carried in the pipes 4C and spaced therefrom are flues 4 which pass through the headers 2 and 2 to front and rear smoke boxes 3 and 3* respectively. Thesmoke boxes 3 and 3 are provided with removable covers. Thimbles pass through the front header 2 and provide a means of communication between the interior of the heater and the front smoke box 3.
The heater is provided with grates 5 which are preferably of inverted V-shape with the apex running from front to'rear in the middle of the heater. hen the heater is in operation the smoke and hot gases pass from the burning fuel between the pipes 4L and thence through the thimbles 6 to the smoke box 3. From thence the smoke passes through the flues t to the smoke box 3, and from thence to a chimney which communicates with the smoke box 3*, and is not shown.
The interiors of the sides and end communicate freely with fine another. One end of the hopper is closed by the rear header 2*. The other end 10 is adjacent the front of the header and is inclined rearwardly so that the fuel will be fed towards the centre of the grate and for the purpose hereinafter described.
Below the fuel opening 8 is an opening 9 which passes through the header 2 and the smoke box 3, and is provided with a door. When it is desired to use fuel such as Wood slabs or large coal that will not pass through the hopper, such fuels may be manually f ed to the heater through this door. The inclination of the hopper end 1O gives room between the hopper end and the grates at the forward end for the insertion of such fuel.
The hopper end 10 is cut away at the bottom to a predetermined extent (as shown at 10) so that the fuel flowing out of the hopper and assuming its natural angle of repose would reach the outer end of the grates. v
The front of the hopper is secured by means of a saddle or bent bar 11 to the header 2. This saddle is secured to the bottom of the fuel opening 8 and to the hopper end 10 by bolts '21. In order to provide circulation of the water in the interior of the sides and end of the hopper, pipe connections are provided which communicate with the steam and water drums 7 and the header 2. The interior of the sides and end of the hopper communicates with the interior of the steam and water drums by means of pipes 12 provided with unions 13 which are accessible through the fuel opening. These pipes 12 are screwed into the sides 10 of the hopper near the top of the hopper and at the front thereof. Near the bottom of the hopper and at the rear thereof a pipe 141 communicates with the interior of each side 10 of the hopper. This pipe 14 is screwed into the side 10 and passes through a thimble 20, which is formed in the header 2 to the smoke box 3 where it is joined to the pipe 16 by means of the elbow 15. In the pipe 16 is a union 17. The pipe 16-is connected to the pipe 19 by means of an elbow 18, and the pipe 19 is screwed into the header 2 and communicates with the interior thereof.
hen it is desired to use large fuel such as logs the self-feed arrangement is dispensed with and the connections described above make it possible to easily remove the hopper for this purpose. To do this the unions 13 are unscrewed and the' bolts 21 are removed. The cover of the rear smoke box 3 is removed and the unions 17 are unscrewed. The pipe 14 is then screwed out of the wall 10 of the hopper. This leaves the hopper free and it drops to a position opposite the opening 9 through which it is easily removed.
