BURNER.

Specification of Letters Patent.

Patented May 16, 1%32.

Application fi1ed November 22, 1920. Serial No. 425,373.

To all er /1.0m it may concern:

Be it known that I, Hnnlvnin WATERMAN, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a new and useful Burner, of which the following is a specification.

This invention relates to burners designed both for heating and lighting purposes, one of the objects being to provide a burner which can be applied readily to an ordinary gas fixture and which utilizes a detachable reflector having a covering of asbestos or other incandescent material, the said reflector being easily replaced when worn out.

A further object is to provide a burner the eiliciency of which is materially increased by providing outlets in the top or head of the burner for the escape of heat around the reflecting ring. 1

A. still further object is to provide a sim plified connection between the base and the top of the burner whereby the two may be adjusted relatively to each other quickly for the purpose of regulating the efficiency of the burner as either a heating or a lighting medium.

The invention is designed primarily as an improvement upon the structure dis closed in the patent to L. F. Betts No. 744.283, owned by me.

With the foregoing and other objects in .view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in. the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings the prelerrcd form of the invention has been shown.

Tn said drawings Figure 1 is a view partly in front elevation and partly in section of the burner.

Figure 2 is a section on line 2-2, Figure 1 showing the base in plan.

Figure 3 is a section taken on the same line as is Figure 2 but showing the top or head of the burner in bottom plan.

Figure 4. is an enlarged section on line 4- l, Figure 2.

Referring to the figures by characters of reference 1 designates the base of a burner which is formed of sheet metal properly stamped and assembled to provide a hollow body into which gas is directed through a nipple 2 which is interiorly screw threaded as at 3 and is provided, at its upper end with the usual screen 4:. lllntending from the center of the top of this base is a tubular member 5 likewise formed oi? sheet metal. The body 1 has an annular series of small apertures 6 provided in an oilset portion 7 which extends annularly around the body at the top thereof. A top plate 8 is mounted on the tubular member 5 and above and spaced from the body 1. This plate has an annular flange 9 depending the efrom and extending downwardly below the plane of the openings 6 and spaced from the periphery oil the body 1. Reen'forcing ribs 10 are formed radially on the plate 8 and formed in said plate and between the ribs are radial slots 11. One of these slots is provided above each. of the openings 6 and, as shown. in Figure 2. all oil the slots are extended beyond the margin of the body 1. This is done so as to allow iresh air to circulate upwardly between the body 1 and the flange 9 and through the slots 6 along straight lines and without the necessity of following tortuous paths which would tend to tilt the burner. The plate 8 is held down to proper position by lugs or projections 12 which are struck outwardly from the member 5. For the purpose of holding the plate 8 against rotation relative to the body 1. there is provided a pin 13 upon the body which extends into an opening 14; in the plate 8.

Seated within the tubular member is the lower end of a tubular support 15 formed of sheet metal and on the middle portion of which is provided a deflecting ring 16 the upper and lower walls oi which converge outwardly to the edge 17 oi. said ring. The upper end of the tubular support projects into a tubular member 18 which erttends downwardly from the center of the top or cover 1.9 oi. the burner. The cover or top 19 is formed of sheet metal and has its central portion preferably depressed. as shown at 20 while an annular flange 21 is provided around the top or cover and preferably describes an ogee curve as shown. Extending through spaced openings 22 within the lower portion of this flange are bendable tongues 23 projecting from the periphery of irusto-conical ring 24. The diameter of this ring is less than the interior diameter of the lower portion of the flange 21 and the bottom face of the ring is provided with a covering 25 of asbestos or similar material. By having the ring 24 proportioned as described there are provided outlet spaces 26 between the ring and the flange 21 as shown in Figure 3, these spaces being separated by the bendable tongues 23.

The tubular supporting member 15 trictionally engages the members 5 and 18 so that it will be held'therein in any position to which it may be shifted. The-burner is adapted to be applied to an ordinary gas fixture and when gas is admitted to the body 1 it will escape through the openings 6 Where it can be ignited, the jets of flame ascending through the slots 11. Here the gas mixes with air entering from between the flange 9 and the body 1 so that a proper combustible mixture is provided. The flame and heat are deflected laterally by the ring 16 so that the heat will be directed against the asbestos lining 25 and the ring 24. This lining will be rendered luminous and the light radiating therefrom will be sufficient to illuminate the room in which the burner is located, this illumination being further improved by the jets of flame deflected toward the top or cover 19 by the ring 16. Not only does the burner thus illuminate the room butit also produces a heat for temporing the room. Likewise utensils can be placed on the top or cover 19 for heating water, for cooking purposes, etc. The burner is rendered especially efiicient as a heating medium because of the extensive outlet openings provided along the periphery of the ring 24 for the escape oi heated air from under the cover or top 19 and also by making the said cover or top with the ogee curved'fiange and with the depressed top whereby an increased radiating surface is provided.

Heretofore where asbestos lined reflectors have been used they have been a part of the top or cover of the bottom and when the lining has worn out it has been necessary to substitute an entirely new top or cover. In the presentcase, however, a new ring can be easily substituted for a worn one simply by bending the tongues- 23 out oi engagement with. the flange 2]. and reinserting tongues 23 of a new ring. Thus the eiliciency of the burner as a heating and light in medium can be maintained.

y having the telescopic connections between the parts of the burners the distance between the'body 1 and the top or cover 19 can be varied'so as to increase or reduce the intensity of the heat coming against the lin- T1; will be noted that all parts of this burner are formed of sheet metal stamped to the proper shape and then assembled. As a matter of fact in practice it has not been found necessary to use any solder although solder can be used under the body 1 for connecting the nipple Q'thereto.

It has been found in practice that by providing the particular annular arrangement of the outlet openings 6, a considerable saving of gas is effected. Furthermore by providing the central depression in the top of the burner the efiiciency of the device for cooking purposes and for heating water is greatly increased.

lVhat is claimed is:

1. In a burner the combination with a body having an annular series oi. outlets for fuel, of a top or cover above the body, a, telescopic connection between the middle portions of the body and cover, and a reflecting ring detachably mounted within the cover and. spaced therefrom.

2. A burner including a body having an annular series of fuel outlet openings, a central supporting member upon the body, a plate extending over the body and mounted on said supporting member, said plate extending beyond the periphery of the body, a depending annular flange upon the plate, there being radial slots within the plate and above the outlet openings, said slots extending over the space between the depending flange and the body, a cover mounted on the supporting member, and a removable incandescent refiecting ring within the cover.

3. In a burner the combination with a body having an annular series of outlets for fuel, of a top or cover above the body, a telescopic connection between the middle portions of the body and cover, a reflecting ring detachably mounted within the cover and spaced therefrom, said ring being trusto-conical, a plate extending over from the body, said plate having a depending annular flange proji-icting below the plane of the outlet qpenings and spaced from the margin of. the body, there being an annular series of radial slots within the plate and above the outlet openings, said slot-s extending over the space between the flange and the body, and means upstanding from the body and projecting into the space for holding the body and plate against relative rotation.

In testimony that I claim the l'ore;,going as my own, I have hereto ailixed my :-:ignature in the presence of two witnesses.
