LEE S. CHADWICK, OF SHAKER HEGHTS VILLAGE, OHIO, ASSGNOR TO THE CLEVE- LAND METAL PRODUCTS COMPANY, OF CLEVELAND, OHIO, A CORPORATION OF OHIO.

STOVE.

Application led February 25, 1922. Serial No. 539,079.

To czZZ whom t may concern.

Be it known that I, Lun Si. CHADwroK, a citizen of the United States, residing at Shaker Heights Village, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Stoves, of which the following is a full,I clear, and exact description, reference being had to the accompanying drawings.

This invention relates to improvements in the class of burners disclosed and claimed in an application liled by me on the 26th day of February, 1921, and b earing Serial No. 418,111.

The burner which constitutes the subject matter of said application is so constructed that the drum or flue may be readily lifted from the combustion device to give unobstructed access to the wick for the purpose of cleaning` or replacing it; or the drum may be tilted with respect to the burner for the purpose of lighting the wick. Also, the drum or flue shown in said application has a double wall, 'the inner wall in the preferred form extending from the top about halfway down the outer wall where it joins said outer wall immediately below air inlet openings, thereby to enclose a space through which a so-called auxiliary current of air mayrse. Also, provision is made for admitting fresh air to the lower end of the drum and deflecting it into close proximity to the wall thereof. rThis arrangement prevents undue heating of the drum and at the same time increases the efficiency of the burner by adding to the quantity of hot air which would ordinarily issue from the top of the drum the auxiliary current of air which has during its Course of travel through the space between the inner and outer walls become heated by radiation from the inner wall.

My present construction possesses all the foregoing features and affords the same advantages as my former construction over the common types of drum burners wherein, as stated in said application, there is a considerable waste of heat and an undue heating of the drum, especially in the region of its upper end.

Objects peculiar to my present invention are the `provision of a burner of the aforesaid class wherein the drum may be very readilj.v lifted from the burner and with equal ease re-placed thereon but which, when placed upon the burner, assumes a positive inge connection therewith so that the drum may-be swung back and entirely out of the way to expose the upper end of the burner, enabling the wick to be readily cleaned or removed, the hinge connection incorporating a stop for limiting the swinging movement of the drum; the provision of a rest for the drum when tilted rearwardly, which rest yields under the weightof the drum and relieves it of the shock which would otherwise be imposed upon it and which would be liable tocrack the enamel wherewith drums of this character are usually coated; the provision of a support for the drum when in normal vertical position, which is independent of the hinge connection between the drum and combustion device, thereby insuring correct relationship between these two units which is exceedingly important in burners of this character as the slightest departure therefrom will disturb the drafts and produce an irregular flame of low efficiency; the provision, in a stove incorporating drum burners of different diameters but of the same height and arranged in transverse alignment, a variable hinge connect-ion between the larger drum and its combustion device enabling it to swing withinthe same vertical space as the smaller drum; and to provide, in such variable hinge connection, means for maintaining the relatively movable parts in a definite relation to each other during the swinging movement.

lThe foregoing objects, and others hereinafter appearing, are attained in the embodiment of the invention illustrated in the drawings accompanying and forming a part hereof and wherein Fig. l is a front elevation of a stove structure embodying my improvements; Figs. 2 and 3 are sections on the respective lines Q-Z and 3--3 of Fig. l, showing the large and small burners, respectively; Fig. 4- is a central vertical section from front to rear through the drum supporting collar burner band that are incorporated in the larger burner; Fig. 5 is a plan of what is shown in Fig. et, with parts broken away to more clearly reveal certain structural details; Figs. 6 and 7 are more or less diagrammatic sectional views of the hinge connection between the drum supporting collar and burner band that are illustrated in Figs. el and 5, Fig. 6 showing the parts in normal position, while Fig. 7 illustrates them in the position assumed upon the tilting of the drum; Fig. 8 is an enlarged central vertical section through the smaller drum and its supporting collar, the burner band being shown in elevation; Figs. 9 and 10 are Views, similar to Figs. 4 and 5, of the drum supporting collar and burner band of the smaller burner, Fig. 9 indicating in dotted lines the manner of applying the drum to the collar; and Figs. 11 and 12 are sectional details on the lines 11-11 and 12-12, respectively, of Fig. 10.

The trame structure of the stove comprises a top 1 that is supported a suitable distance above a base 2 by end panels 3 and a bach wall e, the base, in turn, being sustained a proper distance above the Hoor by legs 5. A tuel supply pipe 10 is supported by and between the end panels 3 'a comparatively short distance above the base 2, and beyond one of theend panels the suppi y pipe has the usual connection with' a fuel reservoir (not shown). Burners 12` and 13 are partly supported by, and have communicative connection with, the supply pipe through elbow fittings 14 that are secured to the supply pipe by suitable clamps 15, and further, by the base 2, through legs 16. The burners are arranged in axial alignment with openings 17 in the stove top, the openings being surrounded by depending flanges 18.

The burner 13 is of the customary size, while the burner 12 is made considerably larger to adapt it to certain purposes heretofore incapable of attainment in stoves of this character. rllhis burner produces an intense heat in a very short time as compared with the smaller burner.

Associated with the respective burners 12 and 13 are the drums or tlues 2O and 21 of appropriate size. Each drum is provided with a window 22 of mica or other suitable transparent material, and with a handle 23.

lt is essential that the drums be capable oi' ready removal trom the burners for the purpose of lighting, cleaning or removing the wicks; and it is desirable to so mount their-.that they may be conveniently lifted from and replaced upon the burners, or tilted with respect thereto so 'as to expose the wick for cleaning, lighting and replacementpurposes, and to this end my invention provides a drum supporting collar that is hingedly connected to the burner and wherewith the drum has a readily separable connection, such connection serving to retain the drum on the collar during the tilting operation while permitting the drum to he easily and naturally lifted from the collar when the collar is in normal position.

lt may also be explained that in burners ot, this character it is necessary to have the drums or tlues very accurately positioned with respect rto the burners in order to properly balance the drafts, so to speak, and produce a clean, odorless, and etlicient llame. To this end, l provide means for supporting the collar, and, through it, the drum, from the burner independently of the hinge connection between the collar and burner, realizing that probable irregularities in the hinge connection would result in an improper relation between the drum and burner, such provision avoiding also the accuracy in the making of the hinge parts and connections which would otherwise be required, thus saving time and labor.

To the attainment of the greatest elliciency, the tops ot the drums must be a certain distance below the lower edges oit the flanges 18 that surround the openings 17 and below which the drums are situated. lt happens that under this arrangement the small drum may swing clear of the flange 13 on a hinge center located to the rear or' the upper end ol: the burner, while with the larger drum 2() it' is necessary to provide a rariable hinge connection between the supporting collar which carries the drum and the larger burner wherewith it is associated. l shall lirst describe the hinge connection of the larger drum collar, with particular reference to Figs. 2, f1, 5, 6 and 7.

So far as they concern my present invention, the burners 12 and 13 are of the ordinary class oit tubular burners, more detailed showings ot which mav be found in my Pat- @ma NOS. 1,246,878, 1,251,638, and. 1,122,856.

A suitable distance below its upper end, the burner 12 (indicated in dotted lines in Fig. 4) is provided with a circumferential bead 25. A. burner band 26 encircles the burner and has a shoulder 27 which rests upon the bead 25, and from the outer edge of the shoulder there depends a "liange 28 that surrounds the bead and is notched at suitable circumferentially spaced points to proride tongues 29 which are clinched under the bead to hold the band against vertical displacement. Extending downwardly and rearwardly from each side of the band 26 is an arm 30, provided with a strengthening bead 31, and which is turned inwardly at its rear end to provide an abutment 32. At points spaced circumterentially of the band 26, lugs 35 and 36 are struck from the material ot the band and turned radially outwardly, those designated 35 being situa-ted toward the trout ot' the burner. whilel those designated 36 are located toward the rear thereof. The upper edges of the lugs and 36 are in a plane parallel with the top ot the burner.

rlhe drum supporting collar is designated generally by the reference numeral 40, and it is formed with a shoulder L11 which rests upon the lugs 35 and 3G and from the outer Ot which a skirt 41-2 depends, the collar Leganes being positioned properly with respect to the burner through the cooperation of said skirts with the outer ends of said lugs. Rising from the inner edge of the shoulder 41 and converging to within a comparatively short distance of the upperI edge of the burner is a wall 43 which joins at its upper edge a gradually flaring defiector 44. Associated with the burner is the usual flame spreader 45 which serves, when the burner is in operation to direct the flame outwardly by virtue of air currents which it controls, and the iame, as it is supplied with air entering between the collar and the burner, follows the deflector 44 outwardly toward the wall of the drum 20 which is supported, through its inwardly directed flange 46, on the external ledge provided by the shoulder 41. The liange 46 has Derforations 47 for the supply of additional air to the drum. Cooperation of the`druirl vith the collar is identical in both burners, and, -as illustrated in Fig. 9 (where the smaller burner is shown), the drum is adapted to be engaged over the collar with its bottom flange beneath a lug at the front of the collar. rlhe lug beneath which the front portion of the drum flange is engaged is designated A in both burners, and by reason of its shape and the formation of the collar, the drum is caused to automatically assume a proper position on the collar with its flange beneath the lug by merel placing the drum over the collar.

Secured, as by spot welding or other suitable means, to the rear side of the skirt 42 of the collar 40 is the base of a hinge plate 50 which carries, at'each end, an ear 51 having an arcuate slot 52 through which a hinge pintle 53 extends that is supported by and between the arms 30 of the burner band 26. Struck inwardly from the skirt 42 of the colla-r 40 are projections 55 which, when the collar is in normal position, are immediately forward of the lugs 36 of the burner band, the projections 55 being inclined downwardly and forwardly from the upper end of said lugs for a purpose which shall presently appear'. The angle between the projections 55 and the shoulder 41 define fulcrum points whereon the collar is adapted to swing with respect to the burner band, the slots 52 of the ears 51, as well as the rear edges of said ears which engage the abutments 32 of arms 30, being formed on arcs which have the aforesaid fulcrum points as their centers. Therefore, during the initial rearward movement of the drum 20, it swings upon these fulc-ruin points until its upper end is clear of the flange 18 (note the arc whose radius is indicated by the arrow a in Fig. 2) and until the upper ends of the slots 50 engage the pint-le 53. During the further rearward movement of the drum, the collar 40 swings on the pintle 53, the upper end of the drum describing an arc the radius of which is designated by the arrow b in Fig. 2. The rearward swinging movement of the collar is positively arrested by the engagement of stops 58, which project upwardly from the ears 51, with the abutments 32; while the drum comes to rest upon a yielding flange 56 that surrounds an opening 57 in the back wall 4 of the stove frame, provided for the accommodation of the drum when swung rearwardly. .In this connection it may be explained that the burner drums are heavily coated with a vitreous enamel, and the shock absorbing quality of the yielding flange 56 protects the enamel Afrom cracking. As will be more appa-rent from the diagrammatic sectional views of Figs..y 6 and 7, the projections 55 are so inclined that they will escape the lugs 36 when the collar swings on the pintle 53; and the engagement of the curved rear edges of the ears 51 with the abutments 32 preventsthe collar from sliding rearwardly on'the hinge pintle when it approaches a position wherein the slots 52 are inclined upwardly and forwardly from the pintle.

I shall now describe the smaller burner, illustrated particularly in Figs. 3, 8, 9, 10, 11 and 12. To the ripper end of the burner 13 is fitted a burner band 60 which has a shoulder 61 that rests upon a bead 62 of the burner. A ange 63 depends from the outer edge of the shoulder 61 and embraces the bead and is notched at points spaced circumferentially of the band to provide lugs 64 that are clinched beneath the bead 62 to hold the band securely in place. Immediately above the shoulder 61, as well as in the region of its upper end, the band engages the burner, but intermediate these points it is enlarged somewhat. Within the rear side of this enlargement is confined the body portion of the burner hinge plate 66, and the ends of this plate are directed outwardly through slots 67 in the band and extend rearwardly from the burner in parallel relation to each other, the ends of the plate being formed into hook shaped ears 63 which carry a pintle 69. The ripper edges of the plate 66, where the ends of the plate protrude through the slots 67 are in the same horizontal. plane as the upper edges of lugs 70 which are struck radially outwardly from the band 6() toward the front side of the burner. A shoulder 72 of the drum supporting collar 73 bears upon the lugs 7 O and upon the aforesaid portions of t-he plate 66 adjacent theV band 60, which portions are designated 75 and are referred to hereinafter as collar supporting portions of the hinge plate. The design of the collar 73 is practically identical with that of the former collar 40, and it comprises the skirt 76 which depends from the outer edge of the shoulder 72, and the upwardly converging wall .77 which rises from the inner edge of said shoulder and which, at its upper edge, merges into the flaring deflector 78. rlhe skirt 76, cooperating with the lugs 70 and the collar supporting portions '75 of the hinge. plate 60 (as illustrated in detail in Figs. 11 and 12) insures proper alignment of the collar with respect to the burner. A hinge plate 8O is applied to the inner rear side of the shirt 76 and terminates at its ends in parallel ears 81 which are extended through slots 82 in the skirt and lie along the inner sides of the upwardly directed rear ends of aforesaid ears 68, the ears 81 having holes through which the pintle 69 extends but which holes are enough larger in diameter than said pintle to afford the collar the freedom of movement necessary to insure its being supported by the lugs 70 and the collar supporting portion 7 5 entirely independently of the hinge. Adjacent its center, the hinge plate 8O has a downwardly and rearwardly extending tongue which constitutes a stop 83 that is arranged to engage the rea-r side of the burner and positively stop the collar, when the drum 21 is tilted rearwardly and rests upon the yielding flange 85 which surrounds the opening 86 in the back wall l which is provided for the accommodation of this drum.

The physical characteristics of the drums 20 and 21 are identical and I shallproceed to describe them in connection with the sectional view through the drinn 21 as it is illustrated in Fig. 8. The drum comprises a cylindrical shell 90 which is provided atits upper end with an upwardly and inwardly extending annular wall 91 that surrounds the outlet opening of the drum. An inwardly directed shoulder 92 is formed at about the vertical center of the drum by beading the shell inwardly throughout its circumference, and resting upon the shoulder 92 is the outwardly flanged lower end of an inner wall 93 which has a converging upper end 94 disposed in close proximity to the aforesaid annular wall 91. Spacers 95 centralize the upper end of the inner wall within the shell 90 and by engagement with the wall 91 retain the tianged lower end of the wall against the shoulder 92. The shell 90 is provided with a series of air openings 96 immediately above the lower end of the inner wall. At its lower end, the shell 90 .is provided with an inwardly directed. base liange 97 which is adapted to rest upon the drum supporting ledere of the collar, and said base flange is provided with a series of perforations 98.

The window 22, previously referred to, is provided by an opening 99 formed in the front side of the drum a suitable distance above the top of the burner so that the flame releases may be observed therethrough, and a pane 100 of transparent material, such as mica, is secured over 'the opening by a. frame 101 attached to the drum as by means of a bolt 102, and a second boit which also serves to secure the handle 23 in ilace.

The druin herein disclosed functions practically the saine as that shown in my former application above referred to. lhen the burner is in operation, a certain Quantity of air enters the space between the drinn supporting collar and the burner and it, with the air which enters tluogi the burner, under the control of the flame spreader, sup plies the oxygen necessary to promote con1- bustion. The burning gases follow the deflector which constitutes the upper terminal of the collar outwardly toward the wall of the drum and are picked up by the fresh air entering through the A carried upwardlyI` the fresh air thus serving to-protect the drum against the direct heat of the tiame. However, by the time this air has reached the lower end of the inner wall 93, it has, by Contact and intermingling with the gases, acquired a very high temperature. The upper portion of the shell 90 is protected from this intense heat by the inner wall 93. The heat radiated by the inner wall creates an upward draft within the space between said inner wall and the outer shell, and this draft is satisfied by fresh air entering` through the openings 96. By the time the air which enters through the opening 96 (hereinbefore referred to as the auxiliary current of air) reaches the top of the drun, it has been so raised in temperature as to materially increase the eficiency of the burner by augmenting the main column of hot gases rising through the drum.
