GAS BURNER AND VE'IILATOR Application le Sctober 6,
' te stantially utilized and turned into heat, with the result maximum heat is obtained from the fuel used and cost of operation of the,
furnace will be reduced to a minimum.
A further object of the invention is to provide anV attachment for furnaces and the like, that produces a constant dow and circulation of draft airs to promote combustion,
` and said How and circulation can be controlled in accordance with the operators desires. i,
Another object of the invention isto provide an attachment for furnaces and the like, that collects and consumes foul air and the like from vthe premises where installed and enables proper ventilation ofy said premises by leaving the same in a pure and clean condition. p
A still further object of the invention is I to provide an attachment for furnaces of the character above set forth that will prevent excess and dangerous accumulation of gases, with the result damageto the furnace by such accumulationfwill be impossible.
, Another object of the invention is to provide an attachment to perform the functions labove referred to, that is extremely simple in "construction, inexpensive to 1 manufacture and is eiiicieit in operation and service.
A still fur her object of the invention is 'to provide an attachment that causes the furnace to consume` smoke before it reahes the atmosphere.
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 inthe appended claims.
' In describing our invention in detail, reference will be had to the accompanying drawture of thel pipe 1 with the 192'?. Serial No. 224,4721..
ings wherein like characters denote like or corresponding parts throughout the several views, and in which:
Figure 1 is a vertical sectional view taken through a steam boiler and showing the application of our attachment thereto.
Figure 2 is. a top plan vie-w thereof with parts in section. i
Figure 3 is a sectional view taken approximately on line 3 3 of Figure 2 and looking in the direction of -the arrows.
Referring to the drawings in detail it will be noted that we have shown our attach-A ment a plied to a tube steam boiler of the vusual construction but it is to be understood that the attachment can be applied to any A:furnace of any kind, type and size without departing from the spirit of the invention.
The steam boiler as shown includes the usual fire box A,y bridging B, boiler C with drafting tubes arranged longitudinally therein, and the letter D indicates the front wall which is in communication with the due E, whilethe flue E is disposed in communication in the usual manner with the smoke stack F.
The attachment which forms the subject matter of the present invention is shown disposed in communication with the flue E and is formed by a vertically disposed pipe l having its lower end spaced from the door as best shown in Figure 1 of. the drawings, and said pipe 1 is supported in such spaced 'relation by depending legs 2. Securedgto the lower edge of the pipe 1 and extending theretrom to the floor is a screen 3 which prevents `e passage of dirt and other foreign matter from being drawn into the pipe as will be readily apparent. l
Secured to-the upper end of the pipe l1 is anelbow 4, and' arranged at the point'of juncelbow 4 and at the front thereof is a'substantiall'y V-shaped depression 5 formed in the pipe toprovide an air passage.- The elbow isA otherwise secured an air. tight and extending laterally `rtherefrom is a pipe -f 6 having fixed to its outer end an elbow 7 the lusual construction and said damper is` disposed slightly below the center of the pipe 1 as shown in Figure 1.
From the above description and disclosure of the drawings, it will be obvious that the pipe 1 is in reality a cold air shaft which is spaced the proper distance from the floor to allow the free passage of air from the i premises as indicated by the arrows in -Figure 1,' and by this construction, it will be apparent that all of the foul air and the likewill be drawn from the premises and beconsumed with the result the premises will be retained in a pure and clean condition as far as the atmosphere thereof is concerned. The air from the pipe 1 is conveyed to the elbow 4 and due to the air passage 5further air is added, which causes further impetus to the air currents. This additional y air helps to convey the air currents through the pipe 9 and elbow 7,-and forces the smoke and unburnt gases which meet the incoming air cur rents substantially in the space of the attachment between the opening 8 and air passage 5 and in the Hue E. back to the lire box of the furnace so that they will be ignited and consumed before being passed tothe atmosphere as will be apparent. The arrows in the furnace indicate the passage of the smoke and unburnt gases in their outward ldirection before they are met by the incoming air from theattachment. The space in the attachment between the opening 8 and air passage 5 acts in the nature of an equalizer, as in the event excessive accumulation of gas should occur in the flue or parts of the attachment, some of the gas will escape through the opening 8, with the result the incoming-air currents from the pipe land passage 5 will always be sufficient to balance with the natural dra-ft below the fire box and retain substantially all of the unburnt -gases in the fire box to be consumed. In view of the commingling of the unburnt gases, smoke and the like with the incoming air, the smoke will be entirely consumed and residue and the like that accumulates 'in the flue and parts of the 'attachment will be reduced to a minimum. The action of the natural draft from below the grate and incoming air currents from the chimney, and the incoming ai'r currentsl from the Iattachment which have atendency to control the movement of the natural air drafts, will commin'gle and cooperate in sucha way tov promote practically complete consumption of t-he products' of fuel in thefurnace, and the action of these respective drafts and air currents will be in the nature of natural respiration. l
It is thought from the foregoing description that the advantages and novel features of our invention will be readily apparent.
We desire it to be understood that we may vmake 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 claims.
vWhat we claim is:
l. An attachment for a furnace, a ue for said furnace, said attachmentcomprising a vertically disposed pipe, legs supporting'said pipe above a floor surface to allow the passage of air thereto, a screen secured to said pipe to prevent the passage of'foreign matter therein, adamper in said pipe and making the same air tight when closed, an elbow secured to the upper end of said pipe, said pipe being provided with a depression formed at the juncture of the pipe with the elbow to provide anA air passage, a second elbow in communication with the flue, being provided with an opening in its top disposed in a line above the air passage, and a pipe .connecting the respective elbows.
2. An attachment for a furnace,'a flue for said furnace, said attachment comprising a vertically disposed cold air shaft, legs secured to and depending from the lower end of the shaft to space' the same froma oor and allow free passage of air to the shaft, a damper in said shaft, an elbow secured to the upper end of said shaft, an elbow adapted to bein communication with the flue and being formed with an opening in its top, a pipe connecting the elbows for` communication with each other, a substantially V-shaped depression formed in the front of `said pipe and at the juncture thereof with its elbow to-provide an air passage as and for the purpose specified.
3. An attachment for a furnace, a flue for said furnace, said attachment comprising a cold-air draft pipe adapted to be vertically disposed and have its lower end arranged in spaced relation with a floor to allow air to pass therein, a damper in said pipe, an elbow secured to the upper end of said pipe, a pipe extending laterally from the flue and being in communication therewith, an elbow secured to the last mentioned pipe and being provided with anv opening adjacent one endand in its top, a pipe connecting the elbow, a substantially V-shaped depression formed in the front ofsaid ipe and at the juncture thereof with its el ow to -provide an air passage.
