Specification of Letters Patent.

Patented Oct. 17, 1911.

Application filed. March 8, 1910. Serial No. 547,976.

To all whom it may concern:

Be it known that I, JEAN BORDEREL, a citizen of the Republic of France, and a resident of Paris, France, have invented certain new and useful Improvements in Bunsen Gas-Heating Burners, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to carry out the same.

' The invention relates to improvements in Bunsen gas heating burners and is more particularly directed to a construction adapted to produce complete combustion of the gas and consequent avoidance of thedisadvantages resulting from the escape of unburned gas from the burner.

The invention will be described in the following specification, reference being had to the accompanying drawing in which- Figure l is an elevation of a burner constructed in accordance with my invention: Fig. 2 is a vertical section on an enlarged scale of the plate or disk located on the top of the burner: Fig. 3 is a plan view of the same: and Fig. 4 is a vertical section of a stove embodying the burner of the invention.

The exterior casing of the burner is formed by a lower shell a narrowing toward the top and of circular cross section, which shell is connected at b to a similar shell a widening toward the top. The shell 0 is surmounted by a cylindrical portion j into the top of which is fitted a plate or disk 01 with perforations of a peculiar form. The gas bracket 70 brings the gas to the center of the base of the shell a.

The plate at has perforations composed of passages preferably or circular cross section narrowing from opposite faces of the disk inward and meeting at their narrowest points; and these perforations stand preferably in a vertical position. It has been found that the best results were obtained when the inferior passages g occupied about one third of the thickness or height of the plate (Z, and the superior apertures f two thirds of the same; although the invention is not limited to those proportions.

The cone-shaped shell on is entirely open at the bottom whereby the air is allowed to move upward around the column of gas discharged from the gas jet, and as the air and gas rise within the shell a they are forced together in proportion as they approach the narrow circle at the junction of the two shells; after which, as they expand in the upper shell 0 the mixture is further promoted by an opposite movement of the particles. At the same time the speed of movement of the mixture is diminished preparatory to entering the cylindrical shell The function of this last named shell is to impart parallelism to the diverging streams of mixed gases so that the whole stream is evenly distributed and delivered uniformly and vertically to the compound passages in the disk cl. These passages complete the mixing process by producing in the separate small gaseous streams which pass through them a repetition in detailof the process more generally and less thoroughly carried out on the whole mass in the lower shells a and 0; that is to say the particles of gas are first thrown together and then allowed to spring apart, thereby producing a mutual oscillation which promotes thorough mixture.

Experiments have shown that with the above described burner the combustion is absolutely complete and that the burned gases contain neither carbon monoxid nor any other noxious gases.

Finally Fig. 4 shows how the burner is adapted to a gas heating stove, it being understood, however, that this burner may be adapted to any kind of heating stoves.

What I claim is- A gas burner, comprising in combination a lower shell for delivering mixed gas and air, and a perforated disk at the top thereof, wherein the perforations taper from opposite faces of the disk inward to a point intermediate said faces, substantially as described.

In witness whereof I have hereunto set my hand in the presence of two witnesses. JEAN BORDEREL. Witnessesr DEAN M. MASON, FRANQOIS DU BOISROUDRAY.
