This invention appertains to new and useful improvements in the art of furnaces and more particularly to a furnace of the hot air type.
The principal object of the present invention is to provide a radiator attachment for hot air furnaces which can be readily installed for use without materially altering conventional types of hot air furnaces now in general use.
Numerous important objects and advantages of the invention will become apparent to the reader of the following specification.
In the drawings:
Figure 1 represents a vertical sectional view through a furnace equipped with the novel radiator.
Figure 2 represents a horizontal sectional view taken substantially on line 22 of Figure 1.
Figure 3 represents a horizontal sectional view taken substantially on line 3-3 of Figure 1.
Figure 4 represents a vertical irregular sectional view through the radiator taken substantially on line 4-4 of Figure 5.
Figure 5 represents a top plan view of the radiator.
Referring to the drawings wherein like numerals designate like parts, it can be seen in Figure 1, that numeral 5 represents the usual casing of the furnace from which the hot air pipe 6 extends.
In carrying out the present invention, an upwardly tapering hood 10 is provided which fits over the fire box 7 and which is provided with a window 11 in the side thereof.
This hood 10 merges with an upstanding pipe 12 around which extends the drums 13 and 14 of the radiator generally referred to by numeral 15.
In the upper drum 13 is located a radially disposed partition 16 merging with the upper end portion of the pipe 12, which pipe has an outlet opening, as at 1'7, immediately at one side of the partition 16. Extending upwardly through the drum 13 are the air tubes 18 arranged in zig-zag relation to each other in a path around the pipe 12.
The air tubes 20 are connected by an annular partition 21 concentrically dividing the interior of the drum 14. ,Extending downwardly from the bottom of the drum 13, at the opposite side of the partition 16 from the inlet opening 1'7, is the pipe 22, which enters the drum 14 on the inner side of the partition 21 and adjacent one side of the radially disposed partition 23 in the drum 14.
The aforementioned partition 21 terminates in spaced relation to the opposite side of the partition 23 so as to provide a by-pass 24 whereby hot air passing downwardly from the drum 13 by way of the pipe 22 can escape from the inner chamher 25 of the drum 14 to the outer chamber 26, from where it can escape through the outlet pipe 27 which is located adjacent the partition 23, on the outside of the partition 21.
Thus it can be seen that the hot combustible materials pass upwardly into and around the drum 13 and then down to and around the drum 14, the hot fumes being retarded by the baffle action of the air tubes.
The cold air passing upwardly through the furnace will pass upwardly through the air tubes 20 in the drum 14, besides contacting with the bottom of the drum and the side thereof and in passing beyond the upper ends of the tubes 20, this air will then strike against the bottom of the drum 13 before passing upwardly through the air tubes 18 therein and out through the air outlet pipes 6.
While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.
Having described the invention, what is claimed as new is: V
A radiator attachment for hot air furnaces comprising a pair of vertically spaced drums, a flue pipe extending through one of the drums and into the upper drum, a conduit connection between the last mentioned drum and the lower drum, an outlet for the last mentioned drum and air tubes extending through the said drums, the air tubes cf the upper drum being offset with respect to the air tubes of the lower drum, so that hot air passing upwardly through the tubes of lower drum will strike against the bottom of the upper drum.
