.AIR-GIRCULATING ATTAoHMEn'rroRHoT-Am nominees; 7
Application filed July 12, 1924. Serial No. 725,6.
To all whom it may concern:
Be it known that I, LEoNG. MYERS, a. citizen of the United States, a resident of Clinton, in the county of De Witt and State of Illinois, have invented new and useful Improvements in Air-Circulating'Attachments for Hot-Air Furnaces, of'which the-following is a specification. I
This invention has reference ,tofan air cir-v culating attachment for hot-air furnaces, and it has for its principal objectto provide for a more rapid circulation of air inhouses or buildings heated by such furnaces; to freshen andchange the air more often, and to provide for introducing the incoming air into the furnace into direct contact, with the wall of the fire-pot and in an even stream, the result of which will cause the rest of the air in the furnace to rise upward and toward the fire-pot, .thus creating a partial vacuum which is filled by air rushingdown the cold air pipe. I a
The invention has for a further object an attachment of the character referred to which includes a blower and air circulating units between the blower and outside wall of the firerpot of a jhot-"airfl furnace, each arranged to deliver in uniform streams the air from the cold "air duct or ducts and being heated by coming into contact with the heated wall of said fire-pot immediately sets up an increased circulation of the air and ac'celeratestheflow of the rest of the air in the furnace, the'result of which is to freshen or change the air'in the rooms to be heated more rapidly than heretofore.
-Th at the invention may be more fully understood reference is had to the accompanying drawings forming a part of the description, illustrating a preferred embodiment of the invention, in which Figure 1 is a view showinga hot-air furnace and my air circulating attachment with a blower associated therewith; I Figure 2 is a horizontal section on the line 22Figu re 1, showing my air circulating attachment associated therewith;
Figure 3 is a perspective view of the head unit or separating chamber, as the same would appear onthe line 83 Figure 1, and Figure tis a cross-section through one of the air conducting ducts, at 4t Figure 1.
Like characters of reference denote corresponding parts throughout the figures.
Referring to the furnace, which may be of any of the well known types'of hot-air furnaces, A designates the fire-pot associated with other necessaryunits'which need not be -here described, all incased within the usual sheet-iron casing B, and supplying air to the chamber surrounding the fire-pot and furnace parts proper within the casing B,
is the usual cold air intake pipe C. Such a pipe ordinarily introduces the cold air to be'heated by the furnace, within the casing B and is heated bythe heat radiating from the wall of the fire-pot and-associated parts and such heated air is taken oif-prgconif ducted to the rooms of a hot-air pipes D. U .c 7
My air circulating attachment is interposedin the cold ai intake pipe C and. by
'fdwelling through means of Lablower forces the sucked i'n-air in an even or balanced stream directly into,
contact with the base of the fire-pot A-and 1n an upward direction. Such an attache, ment preferably includesf'a head, unit or separating chamber 1 divided into-a plurality' ofjairvconducting'passage waysa, Z),
b, '0 and 0 which are of equalarea; 'Gonnected to-said head unit' landcommunicating' with the air'passage-way a to receive and conduct airtherefrom, {is a conducting unit 2 provided with a discharging vent 3 preferably located directly in the rear'iof the furnace, see Figure 2" with the discharge opening of the vent 3 immediately adjacent the wall'of the fire-potjA. i f i Connected to the head unit 1 and communicating with the air passage-ways'b and b, respectivelyto receive" and; conduct air therefrom, are conducting units 4; and 5, which extend, respectively, around and. to the left and right sides of the furnace, see Figure-2, each having a discharging yent 6, extending part way around the fire pot A from the vent 3 of unit. 1, withthe discharge openings vofsa-id vents 6 immediately- 1 adjacent the wall 'of' the fire-pot Al Connected to the head unitl and com-.
municating with the air passageways 0 and a, respectively to receive and conduct air Y therefrom, '8 which extend,- respectively, around and to the left and right sides of the furnace, see Figure 2, each having a discharging vent 9 extending along the forward sides ofxthe fire-pot A fromthe vents 6 of'the units 4 and 5,with the dischar'ge openings of said vents 9 immediately adjacent the wall of the firepot A. I prefer to providetheunits 4, 5,
and 8 with similar dividing or deflecting are. conducting units 7 and partitions 10, preferably located mediate the ends of their respective vents so as to direct the air discharged against the surface of the;
fire-pot in an even or balanced stream thereagains't. As shown 1n the drawings, the several units 2', 4, 5, 7 and 8 are conducting V pipes to the discharge ends of which are connected the respective vents. These vents are ea ch,; somewhat of the form shown in crosssection in Figure 4, i. e., extend upwardly and have contracted months which lie next adjacent the base of the fire-pot and discharge the air in an upward direction against the wall of the fire-pot and over a considerable area thereof. V I 11' designates an electric blower, of any i well known make, to which is connected the inner end of the air intake pipe C, and to which is also connected the intakeend of the head unit '1. I prefer to connect the head unit 1 with the blower 11 by a preferably canvas sleeve 12 or other'universal connection for the purpose of removing all vibration. flAs'will be understood the blower sucks in the cold air through the cold air intake pipe C-and any vents connected thereto and forces such cold air into and through the head unit 1 and ducts connected thereto,
. Such suction willcause a speeding up of the The respective units of the attachment will discharge a constant stream of cold air against the hottest part of the furnace,
and as aresult will cause" the rest of the air within the casing B to rise upward and toward the fire-pot or its superimposed struc-f ture, thus creating a partial vacuum which is filledv by air rushing down the cold air' pipes or vents. The use of the attachment has demonstrated that a more rapid circulation of the air is obtained and in so doing insures a constant change, of air inside a dwellingand a reheating with each passing through the furnace.
The attachment is preferably supported in proper position by a strip or strap of iron 13 conforming to the shape of that part of the furnace against which the attachment is placed, and supported by legs 14.
By adjusting the registersthe amount of return air to any room can be increased or decreased. Comfort is assured and coal ecomony is realized. While not shown, the
. attachment may be controlled by an electric switch conveniently located, or by the use of r a thermostat. Furthermore, the use of such an attachment will prevent the burning out of a fire-pot due to the uniform discharge of cold air thereagainst. V
If desired the attachment may be used in the summer time to effect a constant change of air in a dwelling and thereby keep it cool.
What I claim is 1. An air circulating attachment for hotair furnaces, comprising a head unit prof.
vided with a plurality of cool airconductmg passage-ways of substantially equal area," and a plurality jof conductors connected to said head unit and arranged to discharge air at dlfieren't points therefrom, each 0011- ductor having communication with a distinct passage-way in said headunit and provided at theirdischargeends with upwardly directedcontracted vents.
