CHARLES W. RICE, OF COLUMBUS, OHIO.

GAS BURNER.

SPECIFICATION forming part of Letters Patent No. 746,992, dated December 15, 190 3.

Application filed May 29, 1901. Serial No. 62,338. (No model.)

To all whom it may concern:

Be it known that I, CHARLES W. RICE, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvement in Gas-Burners,of which the following is a specification.

My invention relates to the improvement of that class of gas-burners which are adapted more particularly for heating purposes; and the objects of my invention are to provide a simple although desirable construction of burner of superior construction and arrangement of parts, to so construct my improved burner as to obviate any tendency of the mingled gas and air from blowing out through the burner-openings, to provide one section of my improved burner with a gasreceiving chamber which will serve the double purpose of retarding the force of the gas in its passage through the burner-openings and of providing a thorough mixture of gas and air before the same is discharged atsaid burner-openings, to so construct my improved burner as to overcome the undesirable roaring sound which ordinarily accompanies the burning of gas in burners of this class, and to produce other improvements the details of construction of which will be more fully pointed out hereinafter. These objects I accomplish in the manner illustrated in the accompanying drawings, in which- Figure 1 is a view in perspective of one of my improved burners, and Fig. 2 is a central vertical section of the same.

Similar numerals refer to similar parts throughout both views.

In carrying out my invention I construct the body of my improved burner of upper and lower plate-sections 1 and 2, each of these plate-sections being of the general concavoconvex form shown. The sections thus produced are united at suitable points by vertical bolts 3, which are preferably arranged to pass through bolt bosses or lugs 1 on the inner'sides of said plate-sections. The outer edge portions of each of the plates 1 and 2 are arranged to contact one with the other, one or both of said plateedge portions, however, being provided at intervals with gasoutlet notches or burner-openings, such as are indicated more clearly at 5 in Fig. 1. As indicated in Fig. 1, the lower section 2 may be provided with downwardly-extending supporting-legs 6, while the central portion of the lower section 2 has formed therein an inlet-opening '7, with which is connected one end of a gas-s11 pply pipe 8. In producing the upper plate-section 1 I form therewith about the central portion and on its inner side a downwardly-extending hollow neck 9, the lower termination of which may be at the desired height above thesection 2.

In operation the gas or combined air and gas following the direction of the arrows shown in Fig. 2 passes upward through the supply-pipe 8 directly into the hollow chamber or neck 9 of the upper plate-section, from which the gas is deflected downward beneath said neck and into the body of the burner, where it may escape for ignition through the burner-openings 5.

Heretofore in the use of burnerbodies wherein-the combined gas and air has been discharged directly into the body of the burner and thence outward through the burner-openings it is well known that the initial force of the gas through said burneropenings is such as to prevent the igniting and retention of the flame, owing to the blowing-out action of the former. By my construction it will readily be understood that the combined gas and air is introduced directly from the supply-pipe into the chamber or neck 9, the walls of which serve to retard the gas in its movement toward and through the burner-openings, thus breaking the force and resulting in the production of the steady and comparatively-noiseless flame. It 'will also be understood that the employment of the neck 9 serves to form an additional mixing-chamber for the air and gas, so that the same becomes thoroughly mixed before its exit at the burner-openings.

It will readily be seen that my improved burner is of simple construction, having comparatively few parts, and that the same may be produced in any desired sizes in accordance with the uses to which it is applied.

Having now fully described my invention, what I claim, and desire to secure by Letters Patent, is 1 A gas-burner embodying opposite concavoconvex plates provided upon their inner con- I internal central hollow neck of greater dito caved sides with registered tubular bosses, ameter than the inlet-opening with its open bolts passed through the bosses to connect end surrounding said inlet and lying adjathe plates, the space between said plates I cent to the plate having the inlet.

formin a mixing-chamber, lu s upon the inner fac e of the outer edge poFtion of one of CHARLES RICE the plates to form a peripheral series of out- In presence of let-openings, one of the plates having a cen- O. O. SHEPHERD, tral inlet-opening, and the other having an W. L. MORROW.
