GAS-BURNER FOR FURNACES- Specification of Letters Patent.

To (LIZ 'Uilm/11l it 'ln/(ty ron/cern,.-

Be it known that I, JOHN C. Bnciirmnn, a citizen of the United States, and a resident of Pittsburg', in the county of Allegheny and State of Pennsylvania, have invented a certain new and useful Improvement in Gas-Burners for Furnaces, of which the following is a specification.

My invention relates to fuel-gas burners for furnaces; and my object is to producea burner having a 'cries of burners connected to a common source of gas-supply, the burners being' provided with independent means to mix the air and gas and so disposed with relation to a shield above the same as to throw the iiame outward therefrom and cause the air to ascend up through the space between the burners and the shield to the rear of the iiame to prevent as much as possible the passage of cold air up the walls of the furnace; and to these purposes my invention consists in the novel construction and arrangement of parts hereinafter set forth and described, reference being' had to the accompanying' drawings, forming part hereof, in which- Figure l indicates a plan view of my im- Fig'. 2 is an elevation of the same. Fig. 3 is a section taken on the line 3 3 of Fig'. 1.

Referring to said drawings, l is an annular base or support, the upper edge of which is provided with an outwardly-projecting iiange '0, which serves as a shield or guide to project the flame from the burners toward the walls of the furnace, and an inwardly-inclined top which is bolted or otherwise suitably secured to the gas reservoir or chamber 2, both having' lugs c, which are provided with bolt-orifices for the reception of the bolts Z to admit of this. The said annular support is preferably formed in two parts or sections, the divisional line of which is section-line 3 3 of Fig. l, to enable the same to be quickly and readily placed in the furnace through the door thereof. The said reservoir 2, on the lower side or bottom thereof, is provided with a centrally-disposed boss e, which is screwthreaded for the reception of the upper correspondingly-threaded end of the gas-supply pipe 3. 4 4 are series of radially-disposed gas-discharge pipes constituting' burners, the inner ends of which are screw-threaded and connected to and communicate with the interior of the gas reservoir or chamber 2 and are each provided with an orificef', slightly in advance of the point at which said pipes are connected with the gas-reservoir, whereby air is admitted to each of said burners and caused to mix with the gas prior to its emission through the small perforations g, formed around the periphery of the ared or bellshaped outer end of the said gas-discharge pipes, at which point it is ignited. The said annular base or support has formed therein a number of V-shaped openings it, extending from the lower edge thereof to a point slightly above or on the same horizontal plane with the top of said g'as reservoir or chamber. The gas-discharge pipes project in said openings, the iiared outer end of said pipes terminating approximately on a vertical plane with the periphery or outer edge of the shield of the circular base, forming' a contracted space above and to the rear ofthe burners, the shield forming a guide or deflecting plate, which causes the iiames from the burners to be projected toward and against the walls of the furnace and thereby limit the volume of air or prevent the passage of the same upward against the walls of the furnace between said walls and the burners and at the same time causing the air to pass to the rear of the flame below the shield. The space between the burners forms legs y', upon which said annular support rests when placed within the furnace.

The said burner when arranged for use is placed in such wise in the furnace that the edges of the shield and the outer'ends of the burners are in close proximity with the walls of the furnace, forming a very narrow or contracted space between the burner and the said walls. A ring' m, preferably of asbestos board, upon which said support rests, is arranged upon the grate a adjacent to the walls and in close contact therewith, forminga barrier to the passage of air up through the space between the face of the burners and the walls and causes the air admitted below the burner to pass to the rear of and above the burners, and thus largely minimizing the volume of cold air that may possibly come in contact with the walls of the furnace. What I claim, and desire to secure by Letters Patent, is-

l. In a fuel-gas appliance for furnaces, the combination of a furnace, a gas-chamber therein, a gas-supply pipe connected thereto, a series of independent horizontally disposed burners communicating' therewith, the said chamber having a horizontally-disposed lip or liange constituting a continuous projection above said burners and terminating a short Ioo IIO

and having` a number of' openings in the sides i thereof, a circular centrally-disposed gas-reservoir connect-ed to said annular support pro vided with a gas-supply pipe, a series of ra' dially-disposed gas-discharge pipes connected with said gas-reservoir the outer ends ol which terminate in a semispherieal chamber the periphery ofI which is provided with numerous minute pei-f'oi'ations, and means to supply air to each ot said gas-discharge pipes independently, substantially as set iorth.

3. ln a'f'uel-gas appliance Vf'or furnaces, the combination of' a furnace, a gas-chamber therein, a gas-supply pipe connected thereto. a series ofl independent horizontally disposed burners communicating therewith, provided with independent mixers, and a support connected to said chamber, the upper edge ot' which is provided with a lip or flange terminating a short distance vfrom the walls of' said Vfurnace and constituting a continuous projection above said burners and forming a contracted opening above the burners between said 'flange and the burners and between the walls of said furnace and flange, whereby the air is caused to travel to the rear of` said burners vthrough the space or opening' above said burners. Y

4C. A fuel-gas burner comprising a centrallydisposed gas reservoir or chamber, a series of gas-discharge pi pes connected to and communieating with said reservoir, an annular base or support for said gas reservoir and burners, the upper edge of which is provided with a flange or shield projecting outwardly above the burners, means to admit air to each of said gas-discharge pipes, means to supply gas to said reservoir, in combination with a ring arranged below and supporting said annular base and in close proximity with the walls of the furnace, substantially as set forth.

ln testimony whereofl l have hereunto set my signature in the presence of two subscribing witnesses.
