GAS BURNER AND ASSEMBLY THEREFOR A TTORNEY.

Patented Dec. 11, 1934 UNI-TED STATES PATET OFFICE".

8 Claims.

My invention relates to an improvement in gas burners and an assembly therefor.

'Ihe objects of my invention are; to provide a gas burner that is easy to assemble, easy to make repairs or replacements, and a burner that will operate on low gas pressure andv at the same time have a high efciency.

Referring to the drawings; Fig. 1 is a side view of my gas burner. Fig. 2 is an end view of Fig. 1. Fig. 3 is a plan view of Fig. 1 with one of the burners removed for convenience of illustration. Fig. 4 is a sectional View of the burner supporting frame as seen from the line IV-IV in Fig. 3. Fig. 5 is a sectional view of the burner and assembly as seen from the line V-V in Fig. 3; Fig. 6 is a sectional view of the burner as seen from the line VI-VI in Fig. 5. Fig. 7 is a sectional View of the burner as seen from the line VII- VII in Fig. 5.

The drawings show a gas burner having two burner units A and B, however it is understood that the burner may be made with any number l of burner units such as one, two, four, six, eight,

ten, twelve or more as desired.

25. In the drawings is shown a gas burner frame 10 supported on legs or standards 11 and 11' between which is a gas manifold 12 whichis to be supplied with gas through a pipe 13 which connects to the manifold 12 as shown in Figs. 2, 3, and 5. The frame 10, legs 11 and 1l and mani fold are made integrally or all in onecasting. At spaced intervals on the frame 10 are upwardly projecting flange like elements 14, said anges being short and right angled in shape and ,inte grally connected to the frame element 10 and positioned rectangularly with respect to each other to receive the four corners 'of a rectangular shaped burner and 15 seated' therein, by which means the said burners are spaced apart to provide. an air circulating means between the said burners. In 'the corners of said upward projecting flanges 14 are portions 16 raised above the frame element 10 and on which rest the four corners of the burner. This provides an air space 1'7 between the bottom of the burner and the frame 10, and the

burners

15 and 15 set loosely upon the portions 16 above described, each burner being independent of the other and separately removable. The manifold is provided with removable gas jets 18, one for each burner, said gas jets being threaded into the manifold as shown in Fig. 5. These gas jets are provided with a hole 19 for the gas to jet through from the manifold 13. These jets may be made with different size holes 19 and the jets may be removed from the manifold 12 and be replaced with jets having a different size hole such as is necessary for the proper function of the burner on the gas pressure being used.

The burner is composed of a box like unit having four sides 20, 20'; 20, 20' and a base 21, cast integrally. The base 21 carries a Venturi tube element 22 which registers over the jet Y18 in the manifold 12. The base of the Venturi tube 22 extends below the base 21, while the top of the tube 22 extends a considerable distance above the base 21.

The top cover of the box just described, is an inverted box having four

side elements

23, 23', 23, and 23" each cut away as at 24 as gas ports and the corners such as 25 thus formed act as legs resting on the base 21 as a support for the inverted box. The top of this inverted box has a cover 26 upon the under side of which is formed a portion of a spherical element 27` which regisd `ters above the upper end of the tube 22. The

cover 26 is provided with an outwardly projecting

ange

28, 28', 28" and 28 extending around the four sides of the inverted box to meet the upper edge of the

walls

20, 20', 20, 20', of the rst box like element described. 'I'hese flanges are provided with

slots

29, 30, 31, 32, 33 and 34, and cut away portions to form

slots

35, 36, 3'7, 38, 39 and 40, between the

anges

28, 29, and 31 and the

side walls

20, 20', 20" and 20" of the rst described box like element, said slots functioning as gas ports, attention being drawn to the

blank spaces

41, 42, 43, 44, and 46 which provide a space for afsecondary air supply between the gases coming from the slots adjacent thereto.

The gas under pressure received in the manifold 12 passes through the jet hole 19 where it and air .enter the tube 22 and pass upwardly striking the top elements 27 and 26 and travel downwardly in the' second described box like ele-- ment andY pass through the ports 24 and then travel upvka'rdl'y' in the rst described box like element and vpass out through the

slots

29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39 and 40 where combustion is taking place and secondary air is being supplied between and to the flames through the spaces at 41, 42, 43, 44, 45, and 46 thereby insuring complete combustion of the gases being emitted from the burner. During the course of travel of the gas and air through the burner as above described the gas is thoroughly mixed with the air and again supplemented with air at the point of emission from the burner which provides an ideal condition of the fuel for combustion and permits lOl the burner to be operated on low1 pressure gas without sputtering or back flashes.

Such modifications of my invention may be employed as lie within the scope of the appended claims without departing from the spirit or intention of my invention. Now having fully described myinvention, what I claim as new and desire to secure by Letters Patent is;

l. In a gas burner, a box like element having sides and an open top and a closed bottom, a tubular element, said tubular element being open at both ends and vertically positioned within the box like element and being integral with said bottom and passing therethrough as a means of transmitting fuel into the burner, a second box like element having sides, an open bottom and a closed top, openings in the lower portion of the walls of said second box like element, a flange surrounding the upper edge of said second box like element, slots through said flange and notches in the edge of said flange, said second box like element being positioned within the first said box like element so that it houses the portion of the tubular element contained in the rst said box-like element and the notches in the flange on said second box like element co-operate with the upper edge of the walls of the first said box like element to form slots, said slots being adjacent the slots in the flange.
