HEATING BURNER.

Application filed November To all whom t may concer/n:

Be it known that I, HERMAN J. OSTEN- Donn, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a new and useful Heating Burner, of which the following is a specification.

This invention relates to improvements in heating burners suitable for a fuel consisting of a mixture of air and natural or artiiicial gas, or a mixture of air and hydrocarbon vapor.

One object of this invention is to produce an improved burner of the character indicated which is remarkable for its great heatl ing eliiciency and also for its economy in the consumption of fuel in the attainment of said heating eliiciency. Y j n Another object is to prevent quivering or unsteadiness of the flames issuing from the burner during the operation of the burner.

Another object is tov produce a highly practical burner of the character indicated which is simple and durable in construction, conveniently installable within and remov able from a furnace and comprises simple improved means materially participatingin effecting more complete combustion.

With these objects in view, and to attain other objects hereinafter appearing, this invention consists in certain meritorious features of construction, and highly important combinations and relative arrangements of parts, hereinafter described in this specifi. cation, pointed out in the claims, and illustrated in the accompanying drawings.

ln said draw-ings, Figure 1 is a top plan of a heating burner embodying my invention. Fig. 2 is a vertical section taken along' Y line 2 2 in Fig. 1. Fig. 3 is a horizontal section taken along line 3 3 in Fig. 2. Fig. 4: isa vertical section taken' along any one of lines 1 -t in Fig. 2. Fig. 5 is a vertical section taken along line 5 5 in Fig. 4, except that'in Fig. 5 the handle-forming member illustrated in Figi is shown as having been swung upwardly. Fig. 6 is a vertical section taken along line 6 6 in Fig. 5. Fig. 7 is a vertical section taken along line 7 7 in Fig. 3. Fig.,8 is a horizontal section taken along line 8 8 in Fig. 2. Fig. 9 is a vertical section taken along line 9 9 in Fig. 2. Portions are broken away in the drawings to reduce their size.

My improved burner (see Figs. 2, 3 andV 9) comprises a substantially horizontal metal 17, i925. serial No. 69,597.

base A composed preferably of cast iron and preferably circular externally as shown in dotted lines in Fig. 3; Said base has av screw-threaded hole; 13 formedl centrally of and extending vertically through the base, and thedischarging end portion 14 of a fuelfeeding `pipe is threaded, atl said hole, into said base. Y y

The base A (see Figs. 2, 3 and 8) is .provided, at its top andsubstantially centrally between the hole 13'and the circumferential edge of the base, ,with an upwardly projecting annular rib 15 which 'is' substantially concentric 'in relation tol said hole. Said base is provided, at its topand about centrally between they rib 15 and thecir'cums4 ferential edge of the base, with an upwardly projecting annular rib 16 which is substantially concentric'in relation to and spaced from and surrounds 4the inner rib k15. By

the `hereinbefore described construction it will be yobserved that the base. A extends laterally'of and outwardly from the outer rib y16 of thebase allround said rib.

My improved burner see Figs. 2 and 3) comprises asubstantially vertical hollow met-al body B which is preferably composed of cast iron and has. an interior chamberf17 extending fromlthe base A upwardly into the upper and dome-shaped end portion 18 of said body. Said base constitutes the bot! Va bolt 20 anda nut 21which are applied in any approved manner.' The burner-body B (see Figs. 2 `and 8)-is provided, externally of the chamber 17, with a substantialy horizontal. circumferential flange 22 spaced upwardly 'from lthe baseA and projectinglat# erally of and extending allround said body.

SaidV flange is preferably circular as'shown Y in dotted lines in Fig. 8, and the body'B exf tends above said flange'preferably considerably farther than the distance between said flange and the base A. Said body meas-v ures considerably less inexternal diameter next above `and next below said flange than said body measures in external diameter at its lower extremity, and preferably said flange measures less in .external diameter than the outer rib 16 of the base A.

The burnerbody B (see Fig. 2) comprises a downwardly flaring portion 24 which is arranged under and vspaced downwardly from the flange 22, and'preferably said flaring portion of said body is spaced, at its upper end, considerably farther from the base A than from said flange and forms the greater portion of the body below said flange. The relative dimensions of the flange 22 and the downwardly flaring portion 24 of the body B are preferably such that said flaring portion is arranged substantially wholly under .said fla-nge.

The downwardly flaring portion 24 of the burner-body B (see Figs. 2 and 3) has an annularly arranged series of lateral apertures 25 which are spaced circumferentially of said body and formed preferably under the inner portion of the flange 22 and preferably spaced farther from the base A than from the upper end of said portion of said body. It vwill be observed that. the lower portion of theburner-chamber 17 is reduced in size transversely from the apertures 25 to a point about midway between the flange 22 and said apertures, that said apertures each extend from the chamber 17 laterally and upwardly substantially in a straight. line from the internal surface to the external surface of the downwardly flaring portion 24; of the burner-body, and that said apertures therefore communicate at their inner and lower ends with said chamber and are adapted to discharge laterally outwardly and upwardly at their outer and upper ends and constitute lateral outlets of the chamber below the flange 22.

The burner-body B (see Figs. 2 and 3) is substantially uniform in diameter between the flange 22 and the upperend of the downwardly flaring portion 24 of said body, Aandthe chamber 17 extends from l within said flaring portion vof said body upwardly above said flange.

The burner-body B (see Figs. 2 and 3) is provided, between the flange 22 and the downwardly flaring portion 211 of said body,

with an annularly arranged series of lateral the outlets 26 that the outlets 25 are arranged to discharge toward the discharge from the outlets 26 and that, during the operation of the burner, the flames issuing from the outlets 26 shall be intersecting rela tion, under said flange, to the flames issuing from the outlets 25, so that said flange shall serve as a baffle arranged to limit 'the ascent of said flames between the circumferential edge of said fla-nge` and the burner-body and so that said body shall not have the portion thereof which extends upwardly from said flange impinged against by said flames.

The burner-body B (see Fig. 2) comprises an upwardly flaring portion 27 arranged over the flange 22 and also comprises a short down\\'ardly flaring portion 28 larranged next above said upwardly flaring portion. Ity will be observed, therefore, that the downwardly flaring portion 2S of said body is spaced upwardly from the flange 22, and that said flange measures more in. external diameter than any portion of the body above said flange. 'The downwardly flaring' portion 28 of the burner-body see- Figs. 2 and 8) has an annularly arranged series of lateral apertures 29 which are spaced circumferentiallyv of and con'ununicate with the chamber 17, and said apertures each extend substantially in a straight linel from said chamber laterally and upwardly to the external surface of said flaring portion of said body. lt will bey observed, therefore, that vthe apertures 29 are adapted to discharge Vlaterally outwardly and upwardly at their outer and upper ends and form lateral out,- lets of the chamber 17. Y

The burner-body B (see Figs. 2 and 8) is provided, next above its downwardly flaring portion 28, with an annularly arranged series of lateral apertures 30 which are spaced upwardly from the outlets 29 of the chamber 17 and communicate at their inner ends with and are spaced circumferentiallj-,f of said chamber and extend radially of said body and substantially horizontally from said chamber to the circumferencerof the body. It will be observed, therefore, that the apertures 30 constitute lateral outlets of the chamber 17, andthe outlets 29 are in such spaced relationship to the outlets 3() that the outlets 29 are arranged to discharge toward the discharge from the outlets 30 so that, during the operation from the burner, the flames issuing from the outlets 30 shall be in intersection. relation to the flames issuing from the outlets The burnerbody B extends above the outlets 30 of the chamber 17 and is reduced in size transversely toward itsupper extremity.

@n the base A, adjacent its `outer circumferential edge (see Figs. 2, 3 and 9), is removably mounted or seated a plate C preferably composed of cast iron and surrounding the outer rib 16 of said base and saaeed the base A and serving to preventl material horizontal displacement of said plate on said from said rib all round the rib. v vThe plate C therefore measures more inl internal di- I ameter than the flange 22 and said rib 16 measure in external diameter to permit lowering of said plate into place from above.

body B and arranged opposite and extend-` ing circumferentially of the rear portion and forward portion respectively of and 'spaced somewhat from the circumferential edge of base.

' The plate C (see Figs. 2, 3 and 9) has holes 33 formed between the circumferential edge of the base A and the outer circumference of said plate, and said holes ex-r tend from the bottom to the top of said plate and serve to supply vair from under the plate to. the space surrounding the burner-body between the flange 22 and the' downwardly fiari'ngportion 24 of said body so as to adequately supportcombustion when llames are issuing from the outlets 25 and 26 of the chamber 17 during the operation of theburner. Obviously, the plate C serves as a baflie which, while permitting the passage of air upwardly through the holes 33 from under the plate, does not permit the rush of an excessive supply of air from below the burner to the flames issuing from the outlets 25 and 26 of the chamber 17 dur-` ing the operation of the burner. Y

The baille-plate C also has several apertures 34 spaced from and circumferentially of the burner-body B, as shown in ,dotted line in Fig. 3, and one of said apertures is shown in solid lines in Fig. 7. Each aperture 34 extends to the bottom of vthe plate C, as shown in Fig. 7, and communicates with an upwardly projecting and somewhat upwardly tapering tubular member Y 35 formed` on and at. the top of said plate, and saidaperture serves to supply air from under said plate to said tubular member.

, The top surface of the flange 22 yof the burner-body B, next the outer circumferential edge of said flange (see Figs. 2 and 8) is overlapped Vby a metal plate D preferably composed of cast iron. Said plate D surrounds the burner-body B and has an internal diameter which measures less than the external diameter of the flange 22 and more than any portion of said `body` `above said flange. The kplate D extends yfrom the flange 22 laterally outwardly andisprovided at its bottom with a downwardly projecting annular rib 36 arranged opposite and somewhat spaced from and surrounding the outer circumferential 'edge of said flange. The

plate D constitutes a baille which1retardsfthe.l

ascent of products of combustion from the:` space between the bottom baffle-plate 'C and,`

the flange 22, and eachjtubu'lar membery 35. of said bottom balilefplate (see Figs. 7. and 8) extends into a hole 37 formed in and ex-r tending vertically through the plate:V D.` The hol-es 34 in the baille-plate D are large enough in ldiameter to causesaid plate D to lbe loose in relation to the tubular members 3,5' of the baffle-plate C. Each tubular Vmember35 (see'Fig.k 7) is externallyfprovided,ibe-1ow its. upper extremity, with anv upwardly facing shoulder 38 arranged to form a seat for` the baille-plate, D and preferably. formed by the top of a flange 39 which is formed on and externallv vof saidy member 35 and preferably extends from said plate downwardly to th-e bottom baflle-plate C and thereby reinforces said member- 35. It will beobserved, therefore, that the bailleplate D not. only overlaps the flange 22 but is supported from the tubular members 35j and removable upwardly from said flange and tubular members.

Theburner-body B measures less in external diameter above theH baille-plate D than said plate measures in internal di-v ameter to permit` the' applicationfof said plate from above saidbody. during the assemblage ofA the. parts and to permit-,removal of the plate D upwardly from the flange 22 and tubular members 3 Y Y l The burner-body B (see Fig. 2) isVeX- terna-lly provided, above theoutlets 30 of the, burner-chamber 17, with an upwardly facingy and' substantiallyl horizontal annular shoulder 41 on which is removably mounts ed or seated 'a metal plate E preferably composedn of cast iron and extending around loo l' saidy body, and said plate measures more in. internalr diameter thansaid body mea-v vC and the tubular members 35 of said plate constitute meansl for supplyingfair from nnder said plate to the space extending around the burner-body B at the outlets 29 andB() Y of the chamber 17 and from the plate C to the plate D, so that air is` supplied by said tubular ,members to the space between the plates D and E for the purposel offade'- quately supporting combustion when flames are issuing from said outlets during: the operation of the burner. It will be observed. therefore that; the.k top f plate. I E constitutes a baffle-which retards the ascent of products of combustion from the space between said plate and the intermediate baffle-plate D f during the operation of the burner.

The top baffle-plate E is provided, forward of the burner-body B, as shown in Fig. 1,"with an aperture 43 to permit the application of a lighted match at said aperture for the purpose of conveniently lighting therburner, but obviously the burner may be lit in any'approved' manner.V

The relative arrangement of the baflieplates C, D, and E is preferably such that Vthe space between the bottom baflie-plate C and the intermediate bafiie-plate D, and the space between .said intermediate baffle-plate and the top bafiie-plate E,substantially` correspond in size vertically, andY said plates C, Dfand E preferably correspond in external contour and dimensions.

Each of the baffle-plates C, Dk and E has laterally and outwardly facing straight and parallel side edges 45. Each baffle-plate is provided, at each side edge 45 thereof, with a metal leaf 46 composed preferably of cast iron and extending along and from end to.

end of said edge and pivotally connected, as `will hereinafter appear, to said plate in such a manner as to render said leaf capable of being swung upwardly and toward the burner-body B. Each baffle-plate is provided, at each of two points spaced longitudinally of each .side edge 45 of the plate, with an upwardly projecting lug 47, and the leafV 46 extending along said edge is provided, at its top and adjacent said lug, with'a member 48 which is pivoted to said lug by a substantially horizontal pivotal pin 50 arranged longitudinally in relation to said edge. The pivotal pins 50 of the connection between each leaf 46 and the baffleplate provided with said leaf are in line endwise longitudinally of said leaf, and said leaf normally abuts, at its inner longitudinal edge, as shown in Figs. 1, 2, 3 and 8, againstthe adjacent side edge 45 of said plate. By the hereinbefore described construction it will be observed that each leaf 46 of each baffle-plate is arranged to be swung upwardly from the position shown in Figs. 1, 2, 3, 4 and 8 into or inwardly beyond the upright position shown in Figs. 5 and 6, and that said leaf, when it has been swung upwardly into said upright position, serves as aV handle for convenience in manipulating or handling the baffle-plate and to enable the passage ofthe baffle-plate through a doorway having less width or dimensions than would be required were said leaf not capable of being swung into said upright position. It will be observed therefore that each leaf 46 of each baffle-plate also serves as an extension or enlargement of the baffle formed by said plate, and Iwould here remark that said leaf preferably has linger-receiving holes 51 for convenience in manipulating the leaf. f

In installing rmy improved burner in the combustion-chamber of a furnace, the base A and the burner-body B secured to said base are first introduced into said Vchamber and placed in the position required and supported in any approved manner, and the pipe-section 14 may be applied to said base preparatory to or after the placing of said base and attached burner-body in position in the furnace, and thereupon the plate C is passed into said combustion-chamber and over said body and then lowered into place on the base A, whereupon the plate D is passed into said chamber and over the burner-body and lowered into place in rela! tion to the fiange 22 and tubular members 35, and after the application of said plate D the plate E is mounted on the burner-body.

Not unimportant tol a highly successful operation of my improved burner, and to prevent quivering or unsteadiness of 'the' fiames issuing from the burner during its operation, is the extension of the fuel-receiving chamber 17 above the uppermost outlets 30 of said chamber and preferably upwardly into the upper portion ofthe body B to a point above the top bathe-plate E, and I would here remark that IV have, attained highly satisfactory results inthe operationV of burner embodying my invention and having said` chamber gradually reduced in size transversely substantially from said uppermost outlets to the upper extremity of the chamber, as shown in Fig. 2.
