THOMAS J. KELLY,

BURNER FOR or NEW YORK, N. Y.

GAS-STOVES.

Specification forming part ofLetters Patent No. 50,938, dated November 14, 1865.

To all whom it may concern:

Be it known that I, THos. J. KELLY, of the city of New York, have invented a new and Improved Burner for Gas- Stoves; and I do hereby declare that the following is a full and exact description thereof, reference being bad to the accompanying drawings, and to the letters of reference marked thereon.

Similar letters of reference indicate the same devices in all the figures.

To enable others skilled in the arts to comprehend, make, and use my invention, I will proceed to describe its nature, construction, and operation.

The nature of my invention consistsin forming a chamber in the burner between the perforated diaphragm and the external opening, and also in the employment of a vertical diaphragm in combination Wllll an annular opening around the same.

Figure 1 is an elevation of my improved burner, showing a portion of the head broken away to expose the diaphragm. Fig. 2 is a a vertical section of the same, showing its internal construction.

a, body of the burner; b and 0, head formed in two pieces, holding the vertical diaphragm between them and bolted together by the bolt and nut c and g; f,a bar, which Iests upon the lower half of the head, and through which the bolt 0 passes to hold the two halves of the head together; h, external annular opening passiugarouud the headof the burner; i, chamber between the diaphragm and external opening; 7;, supply gas-pipe.

Myinventiou relates to that kind of burner used in gas-stoves; and its object is to gather the mixed gas and air into a chamber after it has passed the diaphragm, and then by a suitable external opening produce an unbroken sheet of flame, by which means I obtain a much greater heat from the same quantity of gas than by burning the gas directly upon the diaphragm.

The operation of my improved burner is as follows: As the gas passes into the body of the burner and is ignited above the diaphragm the heat produces a draft of air into the bottom of the burner, which is left open for that purpose,

the diaphragm together they become perfectly mixed, and by means of chamber t" and externalopeninghtheyare formed into an unbroken sheet, which when ignited gives off more heat than the same amount of gas would otherwise produce.

By the employment of a vertical diaphragm with the annular opening I obtain a very small chamber, bringing the diaphragm very near the external opening, and at the same time I obtain a horizontal flame.

It has been l'ound by experiment that an unbroken flame thrown out horizontally entirely around the top of the burner gives olf more heat when applied to the heating of vessels than several small flames; and it has also been found that by the employment of a vertical diaphragm and placing it so near the external opening that there would be only a small chamber between the diaphragm and said opening, the explosion of the gas in said chamber does not ignite the gas below the diaphragm, as it almost invariably does when a horizontally diaphragm is employed.

These burners may be made of any suitable material and in any desired form.

Having thus described my invention, what I claim, and desire to have secured to me by Letters Patent of the United States, is-

The combination of a vertically arranged diaphragm, d, with the external annular opening, it, as herein shown.

THOS. J. KELLY.
