Filed Oct. 8, .1934 2 Sheets-Sheet 2 Patented Jan. 12, 1937 ATENT OFFICE GAS BURNER Leonard H. Blood, Buffalo, N. Y., assigner to Ernest W. Delzer, Kenmore, N. Y.

Application October 8, 1934, Serial No. 747,448 1 claim.' (c1. 15s-'106)- 'Ihis invention relates to gas burners and has for the primary object the provision of a device of the above stated character which will efficiently mix air and gas to produce a highly combustible mixture capable of producing maximum heat units from a comparatively low pressure gas supply.

With these and other objects in View this invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my invention reference is to be had to the following description and accompanying drawings, in which Figure 1 is a side elevation partly in section illustrating a burner constructed in accordance with my invention.

Figure 2 is a fragmentary top plan View illustrating the same.

Figure 3 is a fragmentary plan View partly in section illustrating one of the sections of the manifold and having associated therewith a series of mixing units.

Figure 4 is a sectional view taken on the line 4-4 of Figure 3.

Figure 5 is a plan view illustrating a base plate.

Figure 6 is a plan view illustrating the pedestal or support on which the base plate and other units of the device are mounted.

Referring in detail to the drawings, the numeral I indicates a support consisting of a vertically arranged post 2 removably secured to a base 3. Secured to the upper end of the post 2 is a collar 4 provided with screw threaded sockets to receive the screw threaded ends of radially arranged supporting arms 5. The arms have mounted thereon a base plate 6, centrally apertured to receive the collar 4, the upper surface of the latter being flush with the upper surface of the base plate 6. It is preferable that the base plate 6 be constructed of sections joined together, as shown at l, to facilitate the assembling of the base plate to the collar 4. The base plate supports a manifold 8 of annular formation and consisting of semi-circular tubular sections 9 each having its ends closed by plugs which are preferably welded in said ends of the sections of the manifold, as shown in Figure 3. Integral with the sections of the manifold are depending pipe sections I0 which extend through openings in the base plate 6 and are provided with couplings I I by which supply pipes (not shown) may be connected to the manifold. Secured to the sections 9 of the manifold are a series of nipples I2, the latter being preferably threaded into openings formed in the sections of the manifold and are in turn threaded to mixing units I3. The nipples I2 support the mixing units I3 in upwardly and outwardly disposed directions with respect to the manifold and each unit consists of a body provided with bulged portions forming therein primary and auxiliary mixing chambers I4 and 5. One end of the body is recessed and screw threaded to receive the nipple and como municative with the nipple is the bore I6 of a jet I'I terminating approximately centrally of the primary mixing chamber I4. Air ports I8 are arranged in the walls of the mixing cham'- bers I4 and I 5, the air ports of the mixing chamber I4 being disposed rearwardly of the free end of the jet Il. Cast integrally with the mixing chamber I4 and extending into the mixing chamber I5 is a nozzle I9 disposed in alignment with the jet I1 and terminating substantially centrally of the mixing chamber I5. The outer end of the body is shaped to form a nozzle 20 aligning with the nozzle I 9. The ports I 8 of the mixing chamber I 5 are arranged rearwardly of the free end of the nozzle I9. The gas from the manifold enters 25 the primary mixing chamber I4 by way of the jet I1 and this gas passing towards and through the nozzle I9 draws air through the ports I8 of the primary mixing chamber I4. The air and gas thoroughly mix and enter the auxiliary mix- 30 ing chamber I5 with considerable velocity. Additional air is furnished the mixture in the auxiliary mixing chamber I5 by the ports I8 thereof so that the fuel escaping from the nozzle zo will be of a highly Combustible nature, it being 5 understood that the fuel burns at the end of the nozzle 20 and is capable of producing maximum heat units.

A deilector 2| consists of a conical-shaped portion 22 and an annular shaped portion 23, the latter being arranged within the manifold and resting upon the base plate 6 with the conical portion inclining upwardly over the mixing units. The deector being of the shape described, will deflect air currents upwardly and outwardly with respect thereto and said air currents aid in directing the ames from the mixing units in a corresponding direction. Carried by the deflector on the annular portion 23 thereof are bars 24 which overlie the manifold 8 and aid in retaining the device in proper assembled position, the outer ends of said bars being bent upwardly and outwardly at approximately the same inclination as the mixing units and the 55 conical-shaped portion 22 of the deilecto'r. The arms 24 project a short distance beyond or outwardly of the mixing units and this arrangement of the parts maintains the device when assembled in a centrally located position in a furnace in such manner that the burner units are maintained at the proper distance from the walls of the furnace, for the greatest degree of eciency.

A burner of the character described can be shaped or designed to t a re box either of annular formation; rectangular shape or a box of any other shape which may be desired in 'the construction of a furnace.

Having described the invention, I claim:

A gas burner including a stand, a horizontally disposed base removably mounted on said `stand and including detachably connected semicircular shaped sections, a deflector including an annular portion resting on the base and a frusto-conical shaped portion extending upwardly and outof said mixing chambers having air ports and being of substantially spherical shape, and horizontally disposed arms secured to the annular portion of the deflector and resting on the manifold between certain of the mixing units and k'having the free'ends thereof bent to extend upwardly and outwardly from the base and arranged outwardly of the mixing units.
