MYRON L. snvnnsom or rAssnm, NEW JERSE URNAC Application filcii August '24, 1925. Serial No. 52,026.
This invention relates to irnp'rove'ments 1 in furnaces, the generalobject of tl16'1I1V6I1- tion being to provide a Combined hot air andhot water. furnace so that portions of a building can be heated by hot air and other portions by hot water.
Another object of the invention is to provide the furnace with self-feeding means,
such means being so arranged that a supply of coal can be placed inthe same from the outside of the furnace. I
.A, further object of the invention is to so construct the furnace that the radiating surface of the same is greatly increased.
5 This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.
' In' describing my invention in detail, reference will be had to the accompanying drawings, wherein like characters denote 2 like or corresponding parts throughout the several views, and in which:
Figure 1 is a vertical sectional view through the invention.
Figure 2 Figure 1. Figure Figure 1.
Figure 4.- is a section on line 4.4 of
Figure 1.
In these partofthe furnace and 2 the fire box part between which is the grate 3. The walls of the fire box part are formed with an annular water chamber 4, the lower part of which is connected with a source of supply by the pipe 5 and the outletpipe of which is shown at 6, the pipe 5 also acting as a return pipe when the pipes are connected to radiators or the like. The casing 7 is arranged above the part 2 and forms a combustion chamber, the lower part of which is in communication with the top part of the fire box. The walls of this casing 7 are corrugated so as to increase the radiatingsurface of the combustion chamber and a ring-shaped water chamber 8 is placed on the top of the casing 7, the opening 9' of which permits the products of combustion to pass from said casing 7 into a cap 10 which is connected to a chimney by: the ordinary smoke pipe through means of the 1s a section on line 22 of 3 is a section on line 33 of' views, 1 indicates the ash pit openin g ill; A "hook-shaped partition 12 '15 arranged. in'the cap so, as to cause the products of combustion to passin a circular path through the cap before escaping through the opening 11.- A substantially S-shaped tube 13 passes through the middle part of the furnace and has its lower end arranged to discharge fuel into the fire box 2 with its upper end outside the furnace and covered by a door 14. This tube forms a self-feeder for the furnace, the fuel being placed in the same by opening the door 14. As the lower portion of the tube is arranged in the combustion chamber 7, this fuel will be heated before being discharged into the firebox. An exterior casing 15 and an interior casing 16 have their upper ends connected with the register 17 in the floor of the building and these two casings form a cold air duct 18 for admitting cold air from the room above to the lower part of the exterior casing from where it passes into the space formed by the exterior casing and flows up the same through the central part of the register into the room. The heater 8 can be connected to the hot water boiler or the like by the pipes 8 and a sight opening19 is provided in the furnace so that the interior of the same can be seen. The
casing 16 and the fire box 2 are each provided with a cover 20 of asbestos or the like.
From the foregoing, it will be seen that the furnace is a combined hot air and hot water furnace, with means for heating water shape of the casing 7 increases the radiating surface of thefurnace and the cap 10 and its partition 12 will cause theproducts of combustion to pass over the entire area of the top of the heater 8 before escaping to the chimney.
In starting the fire, the kindling is thrown into the feeder 13 and then it is ignited by throwing burning papers in the ash pit.
Then the coal or other fuel is dumped into the feeder 13 to continue the fire.
A water tank 21 is in communication with the air space of the furnace for moistening the air.
It is thought from the foregoing description that the advantages and novel teatures of my invention will be readily apparent.
I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall Within the scope of the appended claim.
\Vhat I claim is A device of the character described in eluding a tire box, an annular Water chamber surrouiuhng the tire box, an inner and an outer casing supported above the fire box a Water tank at one side of the fire box and neansee having communication with both the inner and outer casings, a third casing arranged within the inner casing having corrugated Walls, a ringdike Water casing at the top of said corrugated casing, a removable cap mounted upon said ring-like Water casing, the said cap :arrying a hook-shaped partition to impede the progress of the products of combustion, and an S-shaped fuel feeding tube passing through the said casings with its inner end opening directly into the fire box.
In testimony whereof I aflix my signature.
