JOHN F. MAINS, OF INDIANAPOLIS, INDIANA, ASSIGNOR OF THREE-FOURTHS TO BRUCE CARR, HARVEY M. LA FOLLETTE, AND EDVARD I. ROBISON,

ALL OF SAME PLACE.

FUEL-GAS BURNER.

SPECIFICATION forming part of Letters Patent No. 461,886, dated October 27, 1891.

I Application led January 2, 1891. Serial No. 376,482. (No model.)

l'o all whom it may concern.-

Be it known that I, JOHN F. MAINS, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Improvement in Fuel-Gas Burners, of which the following is a specification.

My invention relates to an improved fuelgas burner.

The object of my improvement is, first, to so construct the burner that its several parts may be easily molded, and will, when placed together, provide means for the egress and proper distribution of the gas in different vertical planes without drilling or the use of other machine-work, and, second, to provide means for holdlng the several parts of the burner together,which shall be concealed from view and protected from the action of the re.

The accompanying drawings illustrate my invention.

Figure 1 is a plan having the top plate re moved; Fig. 2, a side elevation, and Fig. 3 a

central vertical section. Fig. 4 is a plan of a modified form of the burner.

A is a cast plate having a slightly-raised peripheral edge, in which is a series of shallow notches b b, and having also at its center an opening C for the ingress of the gas,\vhich opening is spanned by a raised open bridge D. Plate A is preferably circular in shape; but it may be oblong, as in Fig. 4, or any other suitable shape. Arranged above and resting upon plate A is an annular tapered ring E, having at its lower edge a radially-projecting flange F and having in its upper edge a series of shallow notches h, similar to the notches b in plate A. Arranged above ring Eis a ring I of similar construction but stnallerin diameter. Any desired number of rings like E and I maybe mounted on plate A, the rings forming the symmetrically-tapered side'walls of the burner, in which the notches b and h form the openingsfor the egress of the gas, which is caused to spread outward by the anges F. The rings are held in position concentric with each otherA and with the plate A by short lugsj, formed upon one and engaging the inner surface of the other. The upper lring is surmounted by a top plate L, havingl a central recess or socket M and a central opening N. The base-plate A and tcp plate L are clamped together, thus holding the rings E and I in place between them by an ordinary carriage-bolt O, which is passed upward through the interior bridge D on plate A into the recess M in the top plate L, Where it receives the nut P. The recess is then iilled with a iire-proof cement. By this construction the bolt is concealed and is protected from the action of the tire. The separate tapered annular rings having openings between them form the side Walls of the burner, having outlets in dierent vertical plane-s for the egress of the gas, so that Vone does not interfere with the other, and they Aare easily and cheaply molded, so that any machine-work on them is rendered unnecessary.

I claim as my invention- 1. The above-described fuel-gas burner, consisting of the base-plate having an inlet-opening spanned by the open bridge D and on its upper side the notches b, the series of annular tapered rings, each having at its base a horizontally-proj ecting continuous flange and a series of notches formed in its upper edge, said rings forming together the inwardly-inclined valls ot the burner, having a series of gas-outlets arranged in different vertical planes, the top plate covering the uppermost of said rings and projecting radially beyond it, and the binding-bolt, all constructed and arranged as shown and described.

2. In a fuel-gas burner, the combination of the base-plate having the interior open bridge D, the annular notched rings forming the side walls of the burner, and the top plate having the recess M, bolt O, and nut P, all arranged to co-operate substantially as set forth.
