BURNER.

Application filed June 17, 1918. Serial No. 240,284.

A To all whom it may concern:

Be it known that I, CHARLES D. MORGAN, a citizen of the United States, residing in the city of Albany, county of Albany, and State of New York, have invented a new and useful Improvement in Burners, of which the following is a specification. The object of "myinvention is to effect a saving in the amount of gas consumed in operatin a gas range for cooking purposes and particularly of the amount of gas necessary to maintain boiling point after the same has been reached. My improvement can maintain a cooking or boiling process with an expenditure of about one-third of the gas consumed by the forms of burners tested by applicant now in use. I am aware that various burners have been covered by Letters Patent for the purpose of conserving fuel but none of these attain the results of my improvementwhich shows a saving of as greater than the most efiicient of these improved burners.

The means by which I secure the efliciency of my burner is by a construction which brings the burner used in contact with the bottom of the vessel to which the heat is being applied. It has been recognized. in this art that the closer the burner could be brought to the vessel to be heated and to the plane of the grid or framework of the stove the more efficient the results would be. This has not been made possible with the form of burners used because it was believed that to get a perfect combustion secondary air supply was necessary and this combustion was not obtainable when the vessel and burner were contiguous to each other. Various methods have been invented and patented to secure perfect combustion through supplies of secondary air and to allow for closer contact between vessel and burner. My form of burner operates without any special allowance for secondary air and may be placed in the same plane as the grid and may touch the vessel to be heated and obtains a perfect combustion. The flame follows the vessel and does not float from under the vessel and because the burner impinges on the vessel the maximum efficiency is secured from the gas used. There is no attempt to supply secondary air by the construction used and the smaller than the mouth itself or the by the reference letter burner mounted thereon.

Similar letters refer to similar parts of the different figures shown.

The mixing tube A is made in elbow form wlth the burner mouth B. The edges of this month are projected inwardly in the form of an annular lip as at C so as to leave an annular opening in the mouth slightly ed es of the mouth may be bevelled and pro ected within the mouth as is shown in Fig. 2. The burner top D is of annular shape and is mounted on the bolt E which screws into the boss F in the mixing chamber A. The art D may be constructed with bevelled e ges as shown in Fig. 2. In Figure 2 the cap has been designated by the reference R, the mouth of the mixing chamber by the reference letter S, the mixin chamber proper and thestem or bolt supportin the burner cap "by the reference letter The supply of gas is sent into the mixing chamber by the cock G and 7 openings for air to enter the mixing chamber are provided atthe points H' the means of controlling the admission of air being those in general use and well known in the art. The burner is secured in the gas range positioned with reference to the grid as is shown in Figs. 1 and 3. The part D being in the same plane as the supporting irons I.

The gas on entering the mixing chamber A is mixed with the air which gets access to the chamber at H and then moves through the mixing chamber to the mouth of the burner where it strikes the part D which is screwed into the boss F so as to leave a space between its'lower surface andthe edges vof the burner mouth B and the mixture trolled by raising and lowering the part D.-

The part D and mouth B when made with bevelled edges as shown in Fig. 2 permit the flame to be turned down to a low point by the cock G without being blown out by possible draughts. I

V I have described preferred forms and do not consider my invention limited thereby as these forms may be materially changed without departing from the spirit of my invention. I

What I claim is:

1. A burner for a gas range consisting of an air mixing chamber comprisin a tube shaped in elbow form with gas an air connections and controls at point of connection, and an outlet port having bevelled edges and having a lip constructed on the lower edges substantially as described; a burner head comprising a solid flat disc mounted above the outlet port and having its edges bevelled so as to make the lower surface of lesser diameter than the upper surface; a

bolt adjustably mounted in base of mix- 2. The combination in a gas range of a mixing chamber with a mouth, an adjustable solid disk mounted above the mouth with a flat top surface adapted to impinge on the bottom of the vessel to be heated, and the grid of the as range, the said grid and the said adjusta le disk being mounted in the same plane.

In witness whereof I have signed this specification in the presence of two witnesses the 12th day of June, 1918.
