Ara DISTRIBUTOR FQB. LIQUID-Font BUR-NERS.
Application filed June 29, 1922. Serial at. 571,672.
a citizen of the United States, residing at ShakerI-Ieights Village, in the county of Cuyahoga andSt-ate of Ohio, have inventeda certain new and useful Improvement in Air Distributors for Liquid-Fuel Burners,v
of which the following is a full, clear, and exact description,reference being had to the accompanying drawings. 4
This invention relates to oil burners, and more particularly to an improved air distributor or so-called flame spreader for use with such burners. i
Devices similar to that constituting the subject matter of this application are shown in my former applications SerialNos. 528,- 813, 528,814, 528,833 (the last mentioned being a joint application of myself and one Marc Resek), filed January 12, 1922, 541,- 898, filed March 8, 1922, andin an application which I am filing concurrently here with and entitled Air controlling member for oil burners, A construction indentical vwith that herein disclosed is exhibited in an application which I filed March '24, 1922, Serial No. 546,349, and wherein the claims are restricted to a safety feature applicable to variously constructed air distributors for oil burners. I
The primary ob ect of the invention 1s to provide an air distributor through which the power and 'efliciency of the 1 burner wherewith it is used is increased and the character of the flame improved, the flame, by reason of the even distrib'ution'o'f air effected by the device, being free from objectionable streaks.
Further objects are to provide a construc' tion which renders the distributor very substantial and durable, imparts rigidity to it, facilitates assembly, expedites manufacture, and which so controls and distributes the air that parts of the spreader are protected from the heat of the flame and therefore maintained at a comparatively low ten'iperature.
Other objects will appear as I proceed to describe the invention by reference to the accompanying drawings which illustrate the present preferred embodiment and wherein Fig. 1 represents a central vertical section through the upper portion of an oil burner and through my improved air distributor 'wherewith the burner is equipped; Fig. 2
isa sectional plan substantially on the line 2 2 of Fig; 1; Fig. 3 is a horizontal sec tion through the burner substantially on the i line 3- -3 of F ig. 1; and Fig. 4'is a planv view of the burner with the air distributor Or flame spreader removed.
The'burnerwherewith'my improved air distributor is designed for use is of the. tubular class but 1t'1s distinguished from the more common ones of this class by it's relatively large size which has acquired for it the name Giant Burner. The burner includes inner and outer wick tubes 1 and.
2, respectively, between which a cylindrical wick 3 is guided, the wick being adapted to be raised and lowered by wick raising means (not shown). A spanner 5 is situated within the upper end of the inner wick tube and is spaced a suitable distance downwardly from the top thereof. This spanner constitutes a support for the air distributor or flame spreader Practically all parts of the air distributor or flame spreader are drawn from sheet metal andothe, same comprises a tubular central structure element 10 which, by reason of its primary functionI shall term the look. This lock is shown as made up of top and bottom sections 11 and 12, re-
The upper end of a supporting member or tube 'fits within the cylindrical part 23 and is secured thereto, as by indentations 31. Secured in a similar manner to the substantial vertical centervofjthe tube 30 is a sleeve 33 which constitutes a part of what is usually termed the flame spreader flange 35. 36 spaced a comparatively short distance below the lower edge of'the dip 25,-and-a slightly raised peripheral portion 37 disposed below the bulged portion 26 of the to 3. fla nge is turned abruptly downwardly over the wick space between the tubes 1 and 2 and this portion of the flange may be referred to as the lip 38.
What is known as the body of the air distributor or flamespreader is designated 40 and it comprises a substantially cylindrical wall which is turned inwardly at its upper end, as shown at 11, and is enlarged at its lower end, as shown at 42. The extreme lower edge'iof this wall occupies a depressed annular bead 43 of a downwardly and in-' wardlyinclined bottom wall 44, said wall be ing provided outwardly beyond the bead 43 with a flange 45 which embraces and is turned over the upper edgeof the enlargement lQ thereby to secure the cylindrical wall and the bottom wall together. The bottom wall terminates at'its inner edge-in a flange etdwhich fits the lower end of the tube 30 and to which it may be secured, as by indentations 4:7.-
A frame is carried by and depends from thespanner 5, and locking elements 51 are pivotally connected at 52 to the frame and have keeper portions 53 which are adapted to be engaged over the abutment 16 of the lock 10 when the locking elements are forced apart by a pin 55 that is slidably supported within the upperend of the lock and which is provided above the top of the'distributor or flame spreader with a knob 56, the pin serving as a means for lifting the distributor or flame spreader from the burner as well as an actuator for the locking elements. strained against undue pivotal movement by stops 57 which project from the top of the frame 50 through openings 58 in said elements. This locking of the flame spreader to the spanner constitutes no part of my present invention-but is fully disclosed and claimed in the aforesaid application of myself and-Marc Resek, Serial No. 528,833; and
the purpose of the frame 50 is set forth in my previously 1nentioned application Serial NO. 528,813.
Extending outwardly and downwardly from beneath the flange 36, toward the lip 38 thereof, is a batlle' 60 which is afliliated with perforations 61 in the downwardly turned edge portion of the flange 36 to make This flange has-a horizontal portion The extreme edge portion of "the The locking ,elements are re-v up a safety feature that constitutes the subject matter of my application Serial No. 5i6,34l9 above referred to.
The spanner 5 is provided with a large central opening 65 and-withia series-of seg mental openings; 66,- and throughout the greater portion of its circumference its edge is spaced --from the innerwick tube by lugs 67 to provide passageways 68. The lock 10' is open at 'its:'-lowe1' end, is provided with large openings 70 in substantially the horizontal plane of the space between the flange 36 and the edge portion "of the top 20, the openings being separated by supporting bars 71, and thetop' wall 13 of the lock has a se-' ries of relativelysm'all openings 72. The
VVhen-the "burner is; in operation, and'is associated with'the other well'known ele-' mentsiwhich go to make up a complete apparatus, such as the drum and the drum supporting-collan as disclosed in Letters Patent No. 84l8,828, issuedApril 2, 1907, to W. R.
Jeavons, there is a current of air induced by the heat of the flameupwardly through the inner wick tube. A part of this air rises through the openings of the spanner 5 into the interior of the lock 10 and the tube 30, the greater" amount of that rising within the lock passing out through the openings 70 to join that within the tube and to escapewith it through the openings and the restricted passageway between the flange 36 and the dip :25 of the top. A certain amount of this air, however, escapes through the perforations 72' in the top wall 13 of the lock; a part through the openingsbii of the top :20, and a part through the perforations 84 and 8501f the respective portions 24land26 'of the top. The air escaping through the passageway between the flange 36 and the peripheral portion of the top imparts proper shape to the flame and, rising between the flame and the top, protects the latter from the intense heat of the flame; This wall of air, so to speak,= is prevented from converging to too great an extent as it rises above the burner by the air which is supplied to the space therewithin through the perforations 84- and 85, the openings 83, and the perforamentioned perforationsserving further to retain the knob 56 perature.
In order that. it may serve its purpose best, the air issuing from between the flange 36 and the peripheral portion of the top must be in a practically unbroken sheet and this is accomplished, notwithstanding voids which may occur in the body of air passing from the interior of the lock 10 and the interior of the tube by reason of the presence of the supporting bars 71 and-7 6 which tend to divide the bodyv of air into radial streams, by the air being smoothed out into a comparatively thin body as it passes through the restricted passageways between the dip 25 and the horizontal portion of the flange 36 and between the extreme edge por-. tions ofthebulgedpart 26 of the top and the flange portion immediatelytherebelow. This is held as an important feature of my present invention. V
A part of the air rising within the tube 30 issues through-the openings 77 into the at a relatively low teminterior of the body 40, and this is augmentthrough the passageways 68 about the edge a of the spanner 5. The air passing through this space prevents vapors dropping from the wick into said space and also prevents the condensation of any vapors therein, the air passing through the perforations 81 serving especially to prevent condensation within the sheltered area immediately above the enlargement 42 of the. body 40.
Attention is directed to the fact that the enlargement of the lock 10, or more specifically the abutment portion 16 thereof, serves as a deflector to direct a proper amount of the air rising within the tube 30 outwardly through the openings 77'tl1ereof. A,
