11 Claims. 1
'I'he present invention pertains to a gas burner and has for its primary object the provision of a gas burner having a central opening and a series of outer and .central ports, and which is so constructed and arranged that the central ports will be readily ignited from the outer ports, will be supplied with goocbsecondary aeration, and the ames held on with high primary air injection.
A further object of the present invention is to provide a new and improved burner having both central and outer ports and in which the central ports will light over quickly from the outer ports.
A further object of the present invention is to provide a new and improved gas burner of the type having a. central opening and having proper secondary aeration through the central opening without blowing llames off the ports.
A further object of the present invention is to provide a new and improved gas burner having a central opening and central ports which can be operated with high injection of primary air without causing the flames from the central ports to lift oil'.
A-iurther object of the present-invention is to provide a new and improved gas burner having central ports located so as to produce high elllciency and good heat distribution.
A further and more specic object of the present invention is to provide a new and improved gas burner having a central openingand central and outer ports wherein the central ports have is of twofpart construction and includes a cap or head I2 and a base il. The cap may be made l of some suitable material such as die cast aluminum, while. the base is preferably made oi cast iron. The two are detachably secured together, preferably by a bayonet type securing means of a type disclosed and claimed in the copending application of Philip S. Harper, Serial No. 533,159, led April 28, 1944, (Patent No. 2,486,278) and assigned to the assignee of this application. The securing means comprises a bayonet member I6 having oppositely extending arms I1 (only one of which is visible in Fig. 2) and secured to the cap in suitable manner, and a pair of lcooperating cam defining portions of lugs i8 (only one of which isshown) which are preferably, but not necessarily, formed integrally with the outer wall 20 of the base.
The outer Wall of the burner base has an inwardly sloping annular seating surface 22 forming a gas seal with a complementary seating surface 24 formed at the underside of the outer wall of associated therewith air baiiles, preferably in the the central ports,lwhich baies prevent the secondary air from blowing off the flames from the ports and which provide a faster lighting of the gas issuing from the central ports from the :llames at the outer ports.. y
Other objects andv'advantages of the present invention will become apparent from the ensuing description of an embodiment thereof, in the course of which reference is had to the accompanying drawing, in which:
Fig. 1 is a top plan view of agas burner constructed in accordance with the present invention; Fig. 2 is an enlarged cross sectional view, partly broken away, taken along theline 2--2 of Fig. 1; Fig. 3 is a fragmentary cross sectional view similar to Fig. 2, illustrating a somewhat different central port arrangement; and
Fig. 4 is a view similar to Fig. 3 of another central port arrangement.
Referring now tothe drawing and first to Figs. 1 and 2, it will be noted that the gas burner l0 vthe cap. The burner base has also a central inner wall 26 having a machined inner surface 28 forming with the machined outer surface 30 of the central inner wall of the cap a thermal seal, i. e., a seal which becomes highly eiective as a gas seal when the burner cap is heated and expands in operation. The parts fit relatively loosely prior to heating in operation so that the cap may be readily inserted into its indicated position and then turned so as to be locked in place by the opposed arms I1 of the bayonet member I6 and the opposed oppositely located lugs I8.
The burner is of the type having a plurality of outer ports 32 and also a plurality of central ports 34 located at slightly lower level than the outer ports. ports 32 will be lighted rst by suitable lighting means, not shown, and that the inner ports will be lighted over from the outer ports. As already indicated, the primary object of the present invention is to provide an improved arrangement of this character and especially one in which good secondary aeration will occur without the flames of the central ports being blown oil and wherein the lighting of the central ports will occur quickly and wherein high injection of primary air can be used'and, furthermore, to provide a gas burner wherein the central ports are located to produce high 4eiciency and good heat distribution.
The outer ports 32 are preferably formed by openings inclined somewhat downwardly and inwardly and passing through the outer wall 36 y'of the burner cap. These ports, it may be noted.
It is contemplated that the outer f are staggered so as to provide good aeration and holding characteristics. In accordance with the present invention, th central ports 34 have associatedf therewith air bailles preventing the secondary air,-which rises through a central opening 38 in the burner cap, from .directly sweeping by the ports at high velocity and lifting the gas issuing from the centrai ports or the lifting of the flames present after ignition. In the illustrated embodiment of the invention, the bafes are constituted by generally diametrical bars I which, for structural reasons, are united centrally as indicated by the reference character 42. The ports 34 are located inwardly oi and slightly above bars and are in line with the bars, thereby preventing the secondary air from sweeping directly past the ports at high velocity. The ports are also located in pairs, thereby to enhance their holding on characteristics.
The size of the central opening 38, or the sizes of the individual ports 38A thereof, is so chosen that sufficient secondary air is provided. As a result. the ports 34 are located on a larger circumference with the further result that a more uniform heat distribution over a greater area is obtained.
The baiile bars 40 reduce the velocity of the secondary air flowing past the central ports thereby preventing the secondary air from lifting the ames oi and also preventing the secondary air from blowing the raw gas away from the ports which would otherwise result in the slowing down of the lighting over and even causing failure to light over. The lighting over with the arrangement of the inventionoccurs quickly because the bars prevent the raw gas from being blown away. The arrangement also enables good secondary aeration to be effected because the secondary air does not blow the flames oi the ports. Furthermore, high injection of primary air may be utilized because the deleterious effect of the secondary air is minimized. High eiliciency and good heat distribution are another attribute of the present invention, this resulting from the location of the central ports upon a greater circumference.
The embodiments of the invention illustrated in Figs. 3 and 4 are closely similar to that described above. The only differences are that in Fig. 3 the individual central ports 34 of the pairs are spaced vertically with respect to each other rather than horizontally and in Fig. 4 the central ports are constituted by single ports 44 lon cated radially beyond and centrally above each cross bar 40.
While the invention has been described in connection with the details of three illustrative em bodiments, it should be understood that such details are not limitative of the invention, except in so far as set forth in the accompanying claims.
