BURNER ATTACHMENT.

Specification of Letters Patent.

Patented June 21, 1910.

Application filed September 14, 1909. Serial No. 517,685.

To all whom it may concern:

Be it known that I, THOMAS TVIOWOOM- BER, citizen of the United States, residing at Elkland, in the county of Tioga and State of Pennsylvania, have invented certain new and useful Improvements in Burner Attachments, of which the following is a specificat-ion.

This invention relates to gas burners and refers particularly to an attachment to be applied to burners which are adapted for use in furnaces or the like.

An object of this invention is to provide an attachment to a burner which will cause the more thorough combustion of the gas by the peculiar arrangement of the attachinent whereby a greater supply of oxygen is introduced into the gas as it issues from the nozzles of the burners.

The invention has for a further object the provision of an attachment of this character which includes a solid flat member which is positioned in spaced relation about the burner and against which the flame of the burner plays whereby the same is deflected outwardly about the member and caused to draw in an amount of air beneath the member to integrally mix with the gas being consumed and to thereby effect a greater combustion and hence a greater heat and efficiency from the normal amount of gas consumed in the burner with the attachment removed.

The invention further provides anattachment of this character which is applicable to burners of practically any construction and which is formed of but two disks or plates having means for spacing the same apart and retaining the same in position.

For a full understanding of the invention and the merits thereof reference is to be had to the following description and accompanying drawings, in which;

Figure 1 is a perspective View of a burner having the improved attachment applied thereto; Fig. 2 is a side elevation of the same; Fig. 3 is a section on the line 33 of Fig. 2, and Fig, 4 is a top plan View of the lower disk or plate removed.

Corresponding and like parts are referred to in the following drawings and indicated in all the views of the accompanying drawings by the same reference characters.

Referring specifically to the drawings in which is disclosed one embodiment of the in vention as applied to the burner the numerals 10 and 11 designate gas chambers which are opened into pipes 12 and 13 for the introduction of gas into the chambers 10 and 11. A plurality of nozzles 14 are extended from the chambers 10 and 11 for the purpose of leadin gas from the same, which is to be consume The improved attachment which is applied to these burners consists in a lower plate 15 which is disclosed in the drawings as being of circular disk formation and which is provided centrally with a diametrically extended slot 16 which, when the plate 15 is in position is disposed longitudinally between the chambers 10 and 11 for the purpose of admitting of the flow of air upwardly between the burners to commingle with the gas which issues from the nozzle 14.

The plate 15 is suitably apertured as disclosed in Fig. 4, and indicated by the reference numeral 17 for the reception of the feed pipes 12 and 13, which extend into the chambers 10 and 11. The gas chambers 10 and 11 are located immediately against the upper ends of the lower plate 15 for the purpose of preventing the passage of the air from the opening 16 beneath the chambers 10 and 11. The plate 15 is provided With a plurality of standards 18, which are preferably six in number and disposed at the opposite ends of the gas chambers 10 and 11 and intermediately of the outer sides of the same, adjacent the edge of the plate 15, as is disclosed in Fig. 3.

Upon the upper extremities of the standards 18 a second plate or disk 19 is disposed which is of slightly reduced diameter to that of the plate 15 and which is supported considerably above the burners or chambers 10 and 11 to admit of the play of the flame from the burners 10 and 11 against the under side thereof.

In use the lower plate 15 is engaged within the fire-pot of a furnace to snugly engage with the inner walls of the same and to thereby cause the passage of the air upwardly through the plate 15 between the burners 10 and 11. This position of the plate 15 insures the intermingling of the oxygen with the gas being consumed.

In the operation of the burner and the attachment thereof the pipes 12 and 13 conduct a quantity of gas into the burners or chambers 10 and 11 from which the gas is permitted to escape through the nozzles 14,

which when ignited causes the flame to burn and extend upwardly from the burners 10 and 11. lVhen the plate 15 is in position beneath the burners 10 and 11, which is snugly engaged against the under sides of the burners l0 and 11 air is caused to be drawn upwardly through the opening 16 by the suction caused by the rising of the products of combustion whereby the air is drawn into the flame and supplies an extra amount of oxygen which produces a complete consumption of the gas. hen the plate 19 is positioned above the burners 10 and 11 the flame from the burners plays against the under face of the plate 19 and is deflected upwardly and outwardly about the edge of the plate 19, thus causing a greater suction through the aperture 16 formed through the lower plate 15. It is thus observed that during the burning of the gases a large percentage of the air is drawn in between the burners l0 and 11 and caused to intermingle with the gases being consumed, thereby effecting the complete consumption of the gases and of the production of a greater draft by reason of the suction formed by the flame which plays upwardly and outwardly about the edge of the upper plate 19. Vith this burner a flame is produced which rises a considerable distance above the plate 19 and which thereby intensifies the heat produced from the regular amount of gas consumed by the burner without the attachment so that an economical and eflicient device is produced by the application of this attachment to burners of common formation.

Having thus described the invention, what is claimed as new is 1 1. In combination with a pair of burners disposed in spaced relation and having feed pipes depending from the under sides of the same, a lower plate engaged against the under faces of said burners about said feed pipes and having an aperture formed longitudinally of the burners and centrally therein, a plurality of standards upwardly extended from said lower late, and an upper plate supported on said standards over said burners and having a diameter less than said lower plate.

2. In combination with a pair of spaced burners, a lower plate engaged against the under side of said burners and having an air duct formed centrally therethrough and between said burners, and an upper plate supported in spaced relation above said first plate and having a diameter less than the diameter of said lower plate.

In testimony whereof I affix my' signature in presence of two witnesses.
