Implication filed December 2, 1918. Serial No. 2611,905.

and chamber for burners, and has for its object to provide an exceedingly simple and eiiective device of this character ,which may be readily and quickly applied to burner so as to produce about said burner an air chamber to which air passes at a point below the burner tip or the-Haine issuing therefrom when the burner is lighted so that said air will be preheated and caused to liow directly into the vllame thereby producing a unich larger flame and of course a much brighter light without any addi- 'tional flow of gas and at thev same time the disagreeable odor and smoke will be eliminated.

A 'furtherobject of the invention is to provide a device of the character described which may be frictionally mounted upon a burner any ordinary or well known construction used for lighting purposes and which will so mix the necessary amount of air at the point of combustion thereby rei ducing the consumption of gas or increasing they size and brightness ofthe llame issuing7 from the burner. y

A still further object of the invention is to provide a device of this character which will cause air to be injected into a flame whereby sul'licient oxygen is supplied to create a perfect combustion so that the particles of unburned substances ,which will. throw oit as smoke will be consumed which will eliminate disagreeable odors and 'which will prevent soiled ceilings or wall papers.

The device is designed to be constructed of either one or two parts so that it will be inexpensive in the cost of manufacture, .will have no parts to get out of order and which may be readily. and quickly placed in posi-` tion and adjusted to give the desired size of iiame or bright-ness of light.

lilith these ends in' view this invention consists in the details of construction and combination of elements hereinafter set and useful improvements in combustible smokeless a1r forth and then specifically designated by the claims.

In order that those skilled in the art to ywhich this invention appcrtains may Aunderstand how to make and use the same, I will describe 'its construction in detail referring by numerals to the. accompanying draw-ings forming a part of this application, in which- Figure l, is a side elevation of my improved combustible smokeless air and gas chamber for gas burners showing it applied to a gas burner.

Fig. 2. is a vertical sectional view thereof. the burner being in elevation.

Fig. 3, is a similar view of ag slightly ,modified Yform oli my invention, the. same being removed from the burner.

Fig. 4, is a side elevation oit the nipple used in the construction illustrated in Fig. 3.

Fig. 5, is a side elevation of a still further modiied form of my invention.

Fig. (i, is a plan View oi Fig. l, and Fig. 7, is an enlarged section at the line 7-7 of Fig. 1.

ln carrying out my invention as here cmbodied 2 represents a gas burner of any well known construction and o1 any desirable size and shape, the one here illustrated being the same as is commonly used for suppl ving light and this burner is provided with a slotted tip On this burner is adj'ustably and slidably mounted my improved combustible .smoke less air and gas chamber for gas burners 4 which as shown in Figs. l and 2 consists of a bodyo any desirable shape,size or configuration to snugly lit about a portion of the gas burner in order that the same will lirictionally engage said gas burner so that the device may be adjusted vertically or longi-v tudinally thereon and .which will remain in its adjusted position by the frictional conu tact 'thereof with the burner. From the body projects an enlarged portion" or bowl 6 which may be of any desirable configuration or design and which might enhance the value of the device from the standpoint of beauty.

Above. the bowl will `form air inlets 7 which may be produced by cutting the metal away to leave a number of spaced ribs 8 .with large opening therebetween as shown in Figs. l and 2 or the metal from which the device is produced may be perforated as lill shown at 9 in Fig. 5 and above these air inlets is located a head 10 which is spaced from the gas burner and its tip to produce an air chan'iber 11 and this head is provided with an annular projection or flange 1Q formed in some suitable manner as by producing an outwardly projecting concaveconvex ridge and the extreme upper end of said head is flared outward as indicated at 13 which becomes a guide for the flame issuing from the burner.

In Figs. 3 and 1 I have shown anotherl form of my invention in which the. main portion is an exact duplicate of that shown in Figs. 1 and 2, but to this latter device is added a thimble 14 which is adapted to be placed in the outer or supporting part .flared out vard as at 16 after the manner of the mouth of a bell and this flared portion is adapted to approximately lcoincide with the fiared portion 13 of the outer part of my device so as to support the thhnble and properly position the same and when in use this thimble is spaced from the gas burner 2 in the same manner as the head 10 so that an air chamber is formed about said gas burner.

In Fig. 5, the device shown is the same as that illustrated in Figs. 1 and 2 with the exception that that portion thereof between the bowl G and the head 10 is perforated as before stated to provide the necessary air` inlets communicating with the air chamber 11,

In practice the device is placed upon a gras burner as shown in Figs, 1 and 2 and the same adjusted verticallyor longitudinally of the gas burner in order that the head thereof will be in the proper position vrelative to the burner tip 3 for supplying the necessary air and causing the same to iiow into the flame at the point of combustion. A fter the proper adjustment has been obtained the/air will flow into the air inlets 7 because of the draft induced by the flame issuing from the burner and as this air flows into the air chamber 11 it will be raised in temperature by its contact with the walls of the head 10 so that when mixed with the fiame a necessary amount of preheated oxygen is supplied to cause the ordinary,noncombustible materials to be consumed thereby el i mi nating' smoke and disagrceablcoders. y In actual practice itv has been found that by forming a Harige or ridge 12 about the head just above the air inlet openings much better results are obtained and presumably this ridge acts as a baffle and produces the air eddies or currents which causes a greater amount of air to flow through the air inlets than would be the case if no ridge or flange were provided.

Of course I do not wish to be limited to the exact details of construction as herein shown as these may be limited within the limits of the appended claims without departing from the spirit of my invention.

Having thus fully described my invention what I claim as new and patentable is 1. In a device of the character stated a h ody adapted to frictionally engage a gas burner, a bowl projecting therefrom, spaced ribs formed integral with said bowl and forming air inlets therebetween, a head carried by said ribs of a greater diameter than the burner on which it is mounted thereby producing an air chamber with which the air inlets communicate, said air chamber being' opened at its upper end, the upper end of said head being flared out fard and a concave-convex annular ridge formed on the exterior of said head upon the inlet openV4 ings.

Q. In a device of the character stated a body adapted to frictioallyengage a burner. a bowl,.projectingtherefrom, spaced ribs formed integral with said bowl and forming air inlets therebetween, a head carried by said ribs of a greater diameter than the burner on which it is mounted thereby producing an air chamber with which the air inlets communicate, said air chamber being opened at its upper end,v the upper end of said head. being flared outward, a concave-convex annular ridge. formed on the exterior of said head uponthe inlet openings and a thimble having a flared end adapted to be placed in the head and extended into the bowl so as to be disposed across the air inlets, said thimble having' a flared end for positioning the same and provided with perforations to produce air inlets leading to the air chamber.

3. In a device of the character stated a body adapted to snugly t about a gas burner, an integral bowl formed therewith, an integral perforated portion projecting therefrom of greater diameter than the burner on which it is placed, an integral head formed with said perforated portion also of greater diameter on which the device is placed to produce an air chamber, the perforations in the perforated portion .forming the air inlets to said chamber, the upper end of said head being flared outwardly and anl exterior annular ridge projecting from said head.

In testimony where0f, I have hereunto affixed my signature.
