TAYLOR MATSON, OF PHILADELPHIA, PENNSYLVANIA.

BOILER.

Application filed June 1921. Serial No. 477,638.

My invention consists of a furnace havthey are removable, tion chamber formed an additional combusof opposed water legs,

and fuel flues on said structure, said fiues forming separate heat ng elements for said legs, and communicatlng vertlcal passages connecting said flues forming pluralities off an upper chamber the products of combusfuel receiving lines and 1 adapted to receive tion from said fiues, said fiues serving to subject the water legs to increased heating actions It consists also. of a batiie plate in said heat receiving chamber adapted to cause the ascending products of combustion to be deflected downwardly in said chamber to the place of exit jacket on said therefrom, thus heating a water upper chamber.

. It consists also of a perforated plate which may be lowered in the heat receiving chamber to act to dampen the fire and when not required may be raised the aforesaid baffle plate.

It consists also in forming bricks placed side by above the other withbetween theirjoints structure of separate side and in tiers one out mortar or cement and supported on the fire brick so that air maypass through said joints into the fire pot and with. v

The invention is so supply the latter theresatisfactorily illustrated in the accompanying drawing, but the import-ant instrumentalities thereofpmay be varied, so it invention s not tails shown and limited is to be understood that the to the specific dedescribed, as long as they are within the spirit or scope of the claim.

Fig. 1, represents a partial vertical section and partial embodying my invention Fig. 2, represents a front elevation of a furnace horizontal section thereof on=line 22 of Fig. 1.

Fig. 3, represents a horizontal section of a portion on line 3-3 of Fig. 1.

Fig. 4, represents "a vertical section showing the fuel inlet and the door therefor.

Similar numerals of corresponding parts.

Referring to 1 designates same being composed. of ture formed of fire the drawings 1 the fire pot of reference indicate a furnace, the a fire brick strucbricks 2 placed side by side and imposed in series of tiers one on top of the other and app earing on the exterior of the fire pot they being clamped between the upper and lower plates 3 which are tlghtened by the bolts. 4, the structure being supported on the ash pit 5. 6 is the a1r supply door and 7 its supporting framei Supported on the upper clamping plate 3 of the fire pot structure are the intur'ned water holding sections '8 wh-ose'inner terminal walls are separated forming the vertical fiues or passages 9. The legs are formed of opposite half sections each of which is connected with the side walls 10 provided with flanges 11 through which are passed the bolts 11 whereby said walls and consequently said water. legs may be connected and clamped firmly together.

The walls 10 are set out from the adjacent side walls of the water legs S'providingv water receiving passages 12 which are in communication with the interiorofsaid legs and so have thewater circulate through said legs and passages. 1

The inner side walls'of said legs 8 converge'from the outer walls thereof to the centres of said legs where they join the walls of the passages 9 between adjacent legs forming a series of fuel receiving flues 13, adjacent fiues being in communication by said passages 9 as'most plainly shown in Fig. 2. Said fines are open at the top whereby fuel may be directed into the same. They are also open at the bottom and so placed in communication with the the converging nature of' the side walls of the flu-es 13 they produce large heating sur faces for the water surrounding the fines.

The legs are provided with suitable intakes 14 for supplying the legs with water. The fiues 13 and passages 9 form also comfirepot. Owing to fuel at the open tops of said flues, fuel also descending and entering the fire pot below by which means the water legs are further subjected to the heat from said fiues thus highly heating said legs and consequently producing large volumes of hot water.

Superimposed on the fines 13 is the chamber 15 which is adapted to receive the products of combustion from said flues, the bottom of said chamber having therein the opening at by the swinging perforated damper 17 which being hinged to the adjacent portion of the lower end of the chamber 15 may be lowered over said opening and so serve by its perforations as a damper for the fire when so re- 16 which may be covered in part in elevated position.

properly drawn from the damper the latter quired. The damper 17 may be raised clear of said opening and then held in elevated position by-the catch 18 on the upper limb of the imperforatedbafi'ile plate 19 whose lower end is secured to the adjacent portion of the chamber 15, said plate then rising from said portion to nearly the top of the chamber leaving a passage or space for the products of combustion as shown by the large arrow, Figure '1. The upper limb of the baffle plate is secured to the top of the chamber 15 by the bolt 20." The catch 18 is hinged to the top limb of the baffle plate 19 and its nose portion is adapted to engage the adjacent edge'of the damper 17 and so hold the latter When the catch is is released and so may be loweredover the opening 16 for the purpose h-ereinbefore referred to.

It will be noticed that the chamber 15 is formed of an independent section or a section separate from the sections'of the water legs 8 and fuel lines 13. In the side wall of the chamber is the fuel inlet 21 which is provided with the door 22 which is provided with the damper 23, the latter when not required to be opened being adapted to be closed by the cap 24: which is removably fitted on the wall of said damper.

In the side of the chamber is an opening occupied by the collar 25 for the "exit of the products of combustion and the attachment thereto of the smoke pipe or flue 26. The wall of the chamber 15' is surrounded by the Water jacket 27 The exit of the hot water may be as at 14*.

The fuel is supplied through the inlet 21 and so enters the fiues 13, the passages 9 and the fire pot in the brick structure, the fuel burning from the latter through said passages 9 and flues 13 and the products of combustion then being'directed to the passage or space at the top of the baflle plate 19 the latter being inclined inwardly from one side of the bottom of the chamber 15 to the opposite side thus uncovering the eXitcollar 25 of the exit flue 26 which directs the products of combustion to the atmosphere.

Should it be desirable; to dampen the fire the door 22 is opened rendering the catch 18 accessible. The catch is then operated to release the damper 17 when the latter then drops or lowers on the base of the chamber 15 over the opening 16 therein, when the products of'combustionfrom the tines 13 pass through the perforations or openings in the damper. The bricks S'are placed side by sideand on each other without mortar or cement and so admit air to pass betweenthe joints thereof and so enter the fire pot formed by the brick structure. I p I ld hen the bolts 4 are displaced the fire bricks may be removed from the exterior'of the furnace by being withdrawn outwardly therefrom.

I claim: In a boiler, an ash-pit, a horizontally arranged frame superimposedthereon and se said second section, and a perforated damper secured: to said battle and adapted tobe lowered into a. horizontal position above said first ment-ioned section and in afplane substantiallybelow the opening as closed by'said firing door.
