I AIR REGISTER FOR FURNACES.

Application filed January 23, 1926. Serial'No. 83,395.

the premature discharge of the heated combustion products from the furnace stack, allowing the same to be fully utilized. I

Another and equally important object of the invention is to provide an air register of the character mentioned wherein a novel operating means is employed for collectively moving the Various air regulating vanes whereby to control the supply of air to the furnace combustion chamber, insuring an even inflow of air about the complete structure and through its various discharge ports.

Other objects of the invention will be in part obvious and-in part pointed out hereinafter.

in order that the invention and its mode of operation may be readily understood by persons skilledin the art, I have in the accompanying illustrative drawings, and in the detailed following description based thereon, set out one possible embodiment of the invention.

In these drawings: V p I Figure 1 is a front elevation of the improved register, showing the same mounted in a furnace front, one portion of-the regis ter and the furnace front being broken and shown in section, V

Figure 2 is an enlarged vertical transverse section'taken on the line 22 of Figure 1 looking in the direction in which the arrows point, and U Figure 3 is an enlarged fragmentary'detail, partly in section, showing the mounting of the air regulating vanesadjacent their respective air discharge ports and likewise, the manner in'which such vanes are selectively connectedto the operating ring. Having more particular reference to the drawings in connection with which like characters of reference will designate corresponding parts throughout, the improved air register may be stated to comprise an away annular casing of sheet metal or other suitable material generally indicated in its entirety bythe numeral 1, said casing being provided with an annular air receiving and distributing chamber 2 having an air intake port or opening 3 formed in the lower por tion .Of the inner side wall thereof while a plurality of equi-spaced air discharge ports 4: are formed in the inner wall of the annular chamber 2 and are adapted to discharge air from the chamber into the combustion chamber of an equipped furnace whereby to effect an intimate mixture of atomized oil and oxygen therewithin, thus perfecting combustion.

The casing 1 of the air register is adapted to be arranged in a furnace front, such casing, as will be noted upon reference to Figure 1, having the lateral chamber like lntegr'al extremities 5 and 5 alsocommunieating with the annular chamber 2 of the air register, whereby preheated air will pass thereinto from a point below the furnace '(the heating zone or air heating chamber described and claimedby me in a copending' application for United States Letters Patent'filed January 23, 1926, Serial Number 83,396) and will be fully and evenly distributed about said, annular chamber 2 for discharge from, such annular chamber by way of the circularly arranged and spaced air discharge ports 4 directly into'the I furnace combustion chamber. v

'In 'ord'er that the various ports 4 may be adjusted so as to effectually regulate the discharge of' air from the annular casing 2 into the combustion chamber of an equippet furnace, a plurality of air controlling or regulating vanes generally indicated by the numeral 6 are pivotally mounted inthe opposite side walls of adjacent portions of the casing 1 through the medium of pivot pins 7 certain of the ends ofwhich are ex tendedbeyond adjacent portions of their respective walls and provided with substantially right angularly disposed extensions 8. The free extremities of these extensions'8 are loosely received between relativelyspaced pins 9 securely mounted in. a pair of'juxtaposed operating rings 10; the pins 9, obviously, serving as means for fixedly interconnecting said rings 10 and likewise, for effecting a means of engagement as between such rings 10 and the right angularly extended portions 8 of the aforesaid pivot pins 7 To permit the transmission of rotary adjusting motion to the operating ring constituted by the juxtaposed rings 10, a plurality of radially disposed bracing arms 11 are fixedly connected to portions of one of said rings 10 in the manner shown in the Figures 1 and 3, one of said arms being provided with a handle extension 12 whereby an operator of the device may readily engage the same and impart a rotary or rocking adjusting movement thereto for directing pivotal movement to the various air regulating vanes 6 through the medium of their right angular extensions 8 from the pivot pins 7. By this means of adjustment through the handle 12, it will be fully understood that the air regulating vanes 6 may be minutely and efiiciently adjusted with respect to their adjacent air discharge ports 1 and by consequence, the discharge of an even and uniform flow of air from the annular chamber 2 through the said ports t into the comb-ustion chamber of an equipped furnace will be insured.

A concentrically arranged opening is formed in the outer side wall of the casing 1 and has a sleeve-like bracket 13 secured to the same as indicated at 14; a burner nozzle 15 being extended through this sleeve-like bracket 13 and opening into the combustion chamber of the equipped furnace, whereat, if desired, said nozzle may be supplied with the usual shield 16.

In operation of my improved air register, the casing 1 with the integral extremities 5 and 5 is properly positioned adjacent the furnace front hereinbefore mentioned and through said extremities and the opening 3, it will be understood that a continuous and even inflow of preheated air from the heating zone beneath the furnace and into the chamber 2 will be insured. To regulate the discharge of this air circulating through the annular chamber 2 into the combustion chamber of an equipped furnace, it is only necessary that the operating handle 12 be rocked in the desired direction, thereby effecting a collective pivotal movement of the various air regulating vanes 6 with respect to their particular discharge ports 4 inasmuch as the right angular extensions 8 of thepivot pins 7 are loosely connected to the operating ring 10 in the manner hereinbefore described. By proper regulation of the air regulating vanes 6, it will be understood that an even and uniform supply of air from the various discharge ports 4- into the combustion chamber of an equipped furnace may be successfully maintained. If desired, each of the air regulating vanes may have offset portions 17 formed upon their free extremities, whereby, when said vanes are moved to closed positions as shown in full lines in the V Figure 3, an effectual closure will be had whereby to absolutely prevent the passage of any material quantity of air from the annular chamber 2 through the discharge ports t into the furnace combustion chamber. However, when said vanes are swung to those open positions as shown in dotted lines in the Figure 3, under influence of the operating ring 10 and the operating handle 12, the offset free portions 17 will in no way detrimentally affect the discharge of air from the ports 4:.

Because of the mode of communication of the casing 1 with the air preheating zone of an equipped furnace construction, it will be understood that a continuous and even in flow of preheated air will be effected by way of the properly adjusted or regulated air register per se, into the combustion chamber of such furnace, this preheated air, as hereinbefore described, being evenly distributed about the annular chamber 2 of the register by reason of its mode of introduction thereinto both from the inlet opening 3 and from the lateral integral extremities 5 and 5'. By reason of this mode of air introduction into the chamber 2 and through the ports thereof from the register per se into the combustion chamber of the equipped furnace, it will likewise be understood that an intimate admixture of atomized oil and oxygen within the combustion chamber of the furnace will take place, thus, producing a maximum heating efficiency therefrom.

Manifestly, the construction shown is capable of considerable modification, and such modification as is within the scope of my claims, I consider within the spirit of my invention.
