Application filed May 1, 1919. SerialNo. 293,938.
To (/ZZ 'LUILOHL it may concern Be it known that 1, Joint H. AoKRoYD, a citizen of the United States, residing at Milford, inthe county of New Haven and State of Connecticut, have inventedcertain new and useful Improvements in Gas-Burners andBody=CoveringsTherefor, of which the following is a specification, reference being had therein to the accompanying drawings.
The present invention relates to gas burners of atype such as employed with cooking stoves, cooking tops, hot plates or the like on which cooking utensils are heated.
The chief objects ofthe invention, among otherthings, are to produce a simple, efficient and economical burner; to adapt the burner for general cooking use; and-to provide means to facilitate cleaning of the burner.
The improved burner as a complete artiole, comprises a hollow head, providing a gas distributing chamber having outlets through ports provided in a multiplicity of burner elements, such as bosses or tubes proj ecting upwardly from the top of the burner head and being spaced and grouped thereon in a particular manner so as to define air passages therebetween. A tubular shank extends outwardly from said head in horizontal. alinement therewith and said shank terminates ina cylindrical enlargement, the interior of which forms an air intake chamber, communicating through the passage provided by the bore of said shank, with the gas distributing chamber. in the burner head. The head and shank constitute the body'of the burner. and for thebody aseparable covering plate is provided, which plate, when in position for service, covers theupper surface of the body, the top surface of the head being covered around the bases of the bosses or tubes.
The novel features ofthe improved burner generally described above will be hereinafter. more particularly described in detail and defined by the appended claims.
In order that the invention may be more clearly understood reference is made herein to the accompanying drawings, illustrating embodiments of the invention and in these drawings;
Figure 1 is a top plan view of the complete burner;
Fig. 2 is a longitudinal section, taken upon line 2-2 of Fig. 1;
Fig. 3 is a detail plan view of a modification of a-fiat plate for covering the head of the burner alone; and
Fig. 4 is a plan view showing another modification, consisting of a covering plate shaped to -fit and cover the top of theburner shank.
In the embodiments of the invention illustrated, 1 represents the head of the burner, tubes or bosses 2, each having a longitudinal central bore 3 providing outlet ports for gas passing through the distributing chamher 4; within said head. A tubular shank 5 extending outwardly from said head and formed integral therewith terminates in an enlarged end 6 providing the air intake chamber 7, which communicates by means of the bore 8 of the shank with the distributing chamber 41. Gas may be supplied to the burner through the usualgas supply nozzle 9 and the usual adjustable cap 10 is employedfor coveringthe end of the enlargement 6, botl1 of these parts having the usual registering openings whereby the supply of air admitted for mixture be regulated.
The burner body, inclusive of the burner tubes or bosses, is preferably cast in one piece. The lugs 11 and 12 formed on the bottom of the head 1 provide alternative means for securing the burner in place, the lug 11 being adapted for engagement in the hole of a supporting member, not shown, or the lugs 12 maybe adopted and when used they rest on a cross bar 13, for. example.
The burner tubes 2 are arranged in a group on the topof the head 1, thetops of all'the tubes being substantially on the same level. The tubes are spaced an equal distance apart, to form a hexagonal or other shaped figure, whereby the tubes may be so located or grouped so that straight passages, such as indicated by broken lines a and b are defined, and these passages serve to admit. an equal amount ofair to, allthe flame jets, consequently the jet 14 at the center. of the group will burn with the same uniformity and intensity as the outside jets 15, thus distributing heat equally to the cooking utensil 16, for example, and shown in broken lines (Fig. 2) as being supported on a grid or open top 17 over the burner.
with the gas may It should be understood the hei ht of I plate In av establishes the area of the air passages a and b. In the illustrative embodiment of represented by the number of jets, thirty- I seven in all, and the height of the tubes, as
shown, is substantially correct for a burner of that size and capacity. If another row of tubes is added all around the burner, the capacity thereof will be represented by sixty-one. A burner of such capacity will consume proportionately more air, consequently the height of the burner tubes should be accordinglygreater to establish air passages of greater area.
In a burner having, for example, one less row of jets than the illustration herein, the relative height of the burner tubes would be in accordance with the required area of the air passages. When the burner is in use the air passages a and Z) frequently become obstructed by grease and from overflow in cooking, or from other causes, thus lessening the efficiency of the burner. Periodical cleaning would obviate this defect but for the reason that the burner must be dismounted and bodily re moved for cleaning, which is an inconvenience, proper care is not given to the burner. According to the present invention means are provided to facilitate cleaning or the burner and such means consists of a covering plate having a flat head piece 19 and a tail piece 20. The head piece 19 is provided with perforations 21 grouped and otherwise conforming with the burner tubes 2 so that this piece will fit over the said tubes and completely cover the top surface 18 of the head piece 1. The tail piece 20 rests. on the flat ledge 22 of" the burner shank and covers the top of this latter member. r dependingfiange 23 on the underside of the covering plate serves the purpose of preventing creeping of the grease so that it cannot collect on the underside of the plate, but is caused to drop from the depending flange clear of the burner body. The cov ering plate is self-retained in place by means of the engagement. of the burner tubes or bosses 2 in the perforations 21 and being so held said plate is readily removed for the purpose of cleaning. The said covering be made in. sections and accordingly Figs. 3 and a show respectively the head piece 19 and the tail piece as being composed of separate members. The flange carbon resulting .fixed my signature.
23 extends completely around the plate 19, and when applied to the burner the flange lies below the shoulder 24: andthe end edge 25 or" the tail piece 20 lies below said flange to provide an overlapping joint. The tail piece 20 or shank covering is shaped to fit the shank and in this case the ledge 22 may be dispensed with if desired. The covering plate becomes heated. to a sufi icient temperature to quickly burn to an ash any grease or other matter which may fall upon it. This ash may readily beblown. or brushed ofl While the plate is in its position on the burner body, or the plate may be removed for cleaning.
I do not intend to be restricted to the exact embodiment of the invention shown, but desire to cover all constructions coming within the scope of the annexed claims.
Having described my invention, what I claim as new and desire tosecure by Letters Patent, is:
1. In a gas burner; a body; a plurality of burner elements spaced apart and projecting above said body so as to define air passages therebetween; and a covering plate for said body having pertorations therein and arranged in relation to said body so that said burner elements project through said erforations.
