' tion will be apparent from the following detailed 4 Claims.
still more particularly with a pilot burner provided with a mounting bracket and support for a thermosensitive element responsive to the heat of the pilot flameand operable in conjunction with control means to maintain the supply of fuel for the main burner as long as the pilot flame is burning and to shut off the supply of fuel for the main burner upon extinguishment of the pilot flame.
It is to be understood that the invention, in I its broader aspects, is not limited to the particular use herein disclosed, nor to use of a thermosensitive element with the pilot burner, but may be employed for all similar or equivalent purposes and, in its broader aspects, with or without the thermosensitive element.
Heretofore, pilot burners of the class described, and particularly the pilot burner bodies, have usually been cast to form. The metals suitable for making cast burners of this sort are not now readily available due to war priorities.
One of the main objects of the present inven- I tion is to provide a pilot burner of simple, relatively inexpensive, and improved construction.
and, more particularly, an improved pilot burner.
the stampings, when assembled and joined. to-
gether, permit the inlet fitting or spud and the pilot burner tip to be inserted and secured in the body of the pilot burner in a simple and expeditious manner.
Another and more specific object of the invention is to provide an improved mounting bracket for the pilot burner, which mounting bracket is also formed of a stamping stamped from fiat sheet metal stock, and, .more particularly, a mounting bracket of the class described which is also adapted to support the thermosensitive element in position where it is responsive to the heat of the pilot flame.

Figure 11 is a fragmentary view of the inlet and of the pilot burner body showing the primary air openings formed by slitting or piercing the sides of the body and stamping or pressing the stamnings out in the manner shown.
Referring to the drawings. the pilot burner selected for illustration comprises the main pilot burner body Ill having at one end the inlet fitting or spud I l for supplying gas or other fuel to the pilot burner.
The opposite end of the pilot burner body In is provided withthe pilot burner tip I? drilled and ported at l3 to provide an ignition flame for lighting the main burner when the gas or other fuel supply therefor is turned on. The drilling and porting of the pilot burner tip ii at l3 may be as shown in the drawings. or of any other desired form, many variations of the particular drilling and porting oi: the pilot burner tip at I2 beingwell known in the art. Where a thermoelectric generator (shown in the form of a thermocouple) or other thermosensitive element is used with the pilot burner as shown and described. the drilling and porting of the pilot burner tip also maintains a flame for heating the "hot" junction or junctions of the thermosensitive element.
The burner body In comprises a pair of stampings l5 and 26 formed of any flat sheet metal stock of suitable gauge, such as brass, steel, stainless steel or the like. The stampings I! and I, which are blanked out to provide the formation shown and described, are stamped to form complementary channels-l1 and It for forming, when assembled, a fuel supply passage. The channels l1 and ll are of relatively restricted form intermediate the ends of the burner body to form a Venturi portion indicated in general at It. The channels I1 and I. are stamped to give the pas.- sage defined by the stampings II and II enlarged form at one end of the burner body II at 2', and generally enlarged form at the oppo-' site end of the burner body It at 2|.
l ' langa 22 and 23 extend marginally along opposite sides of the stamping II. The other stamping it has flanges 24 and 25 extending marginally along opposite sides thereof and crimped over the flanges 22 and 23 to join the stampings l and it together and to close, at opposite sides of the burner body, the longitudinal passage defined by the stampings I! and IS. The extended flanges of the stampings l5 and It may be welded together, instead of crimped, or they may be otherwise joined within the broader aspects of the invention.
The pilot burner tip l2 ha a reduced integral neck 2. which fits telescopically in the enlarged end 20 of the longitudinal passage defined by the stampings I! and It. The pilot tip l2 may be secured in the end or the burner body, for example by pressed flt, or by inserting a pin, or
pins, 20 (Figure 2) in an opening, or openings,
ll (Figure 7) in the burner body and into an opening or openings 32 in the reduced neck 29 of the pilot tip upon inserting the neck of the pilot tip into the burner body, or by crimping the pilot tip surrounding portion of the burner body into a groove in the pilot tip, or in any other suitable manner. Alternatively, for example, the pilot burner tip may fit the outside of the burner body or it may be joined to the burner body in any other suitable manner.
The inlet fitting or spud ii for the delivery of gas or other fuel to the interior of the pilot burner body III is inserted or fitted into the opposite enlarged end 2i of the longitudinal passage formed by the complementary enlarged portions of the channels I! and It. The mounting of the inlet fitting ii in the burner body it may be accomplished by various means. In the illustrated embodiment of the invention, a washer I6 is secured, for example, by pressed fit between the stampings l5 and IS with the integral radial flange 38 of the washer abutting the adjacent end of the burner body.
The washer 38 is of the extruded type and is internally threaded at 39 to permit the threaded portion 40 of the spud i I to be screwed into place in the washer 38 with the fuel outlet orifice ll of the spud directed into the adjacent enlarged end of the passage defined between the stampings l6 and II. It is also possible to tap the stampings l5 and it, after they are joined together, along the portion into which the spud II is inserted and to screw the spud I l directly into the pilot burner body ill. The spud II is shown proassure will enter the pilot burner body ll through the spud orifice ll I Diametrically opposite supplementary channels Ill and II are stamped in the walls of the stampings i5 and II adjacent the enlarged end 2| of the longitudinal passage. In Figures v1, 2, 4, 6, and 7 these channels I. and II open endwise from the pilot burner body ll laterally of the flange 38 of the washer II to form primary air admission ports 62 and I! as shown in Figure 4 for the admission of primary air into the mixing chamber formed by the enlarged end 2! of the longitudinal passage. The mixture of gas and air passes outwardly through the Venturi portion ll of the passage and into the hollow interior or longitudinal passage in the pilot tip if, from where it issues through the drilled and ported outlet 13 to maintain, when ignited, the pilot flame for igniting the main burner and for heating the thermosensitive element. The flange it of the washer it is used to control the size of the primary air admission ports 52 and 53, the diameter of the flange controlling the size of these ports.
In the modification shown fragmentarily in Figure 11, the inlet ends of the stampings II,
It are slit or pierced at 90 and the primary air openings ii are formed by stamping or pressing the stampings out, as at 92.
A mounting bracket 58, also formed of sheet metal stock, is stamped to form and provided with an opening I! which conforms, in general, with and fits over the external cross-sectional contour of the inner end of the upper enlarged portion of the burner body Ill and th ioined side flanges thereof. The mounting bracket II has a marginal flange Oil which extends in a direction generally longitudinally of the burner body, and is crimped, for example, at 82 upon the complementary and joined flanges 22, 24,
and 23, '25 for securing the mounting bracket in place upon the burner body. The mounting bracket 58 may be secured in place upon the burner body by other means within thebroader aspects of the present invention. The mounting bracket may be provided with protruding tangs 58a disposed adjacent the crimped or joined flanges of the pilot body and welded thereto for locating the bracket with respect to the body.
vided with a polygonal or other suitably formed Where a thermosensitive element is employed in combination with the pilot burner, the mounting bracket St is provided with a secondopenlng 64, and the thermosensitive element, which is illustrated in the form of a thermocouple II, is mounted in this second opening 64 in position to be heated by the pilot flame.
The form of the thermocouple and lead connection therefor may vary widely within the scope of the present invention. The particular thermocouple and lead connection selected for illustration are of the general character disclosed and claimed in Oscar J. Leins Patent No. 2,126,564, granted August 9, 1938. The thermocouple ll comprises an outer tubular metallic thermocouple member 68 and an inner metallic thermocouple member 81 disposed within the outer thermocouple member and Joined at one end to the outer end of the outerthermocouple member to form the thermojunction 68 which is positioned to be heated by the pilot flame. An inner lead conductor 69 is joinedto the inner thermocouple member 61 to form an internal thermojunction II, and an outer tubular lead conductor. ll surrounds the inner lead 8! and is connected, for example, through a sleeve" tened in place in the opening 64 in the mounting bracket 58 by various means. In the illustrated embodiment of the invention, the thermocouple 65 and the adjacent end of the sleeve 12 are adapted to be passed through the opening 66. The sleeve 12 has an integral annular flange 16 which abuts the mounting bracket 58 as shown.
The sleeve 12, outwardly of the flange I6, is threaded at 18 for threaded engagement with a nut 19 for detachably clamping the thermocouple in place on the bracket 58. Of course the thermocouple and leads therefor may be of existing form and provided with means for detachably securing the same to the mounting bracket 58 without requiring a flange I6 and threads 18 on the sleeve 12 of the thermocouple, as shown and described. If desired, the opening 64 may be threaded and the sleeve 12 may be threaded directly into the threaded opening 64.
The bracket 58 has an integral flange 80 provided with openings 8| through which the bracket is detachably or otherwise secured, for example,
by bolts and nuts 82 or other fastening means,
to the main burner or other support indicated fragmentarily at 83.
In the embodiment of the invention shown in Figures 1 to 8, inclusive, the openings 59 and 64 in the mounting bracket 58 are shown spacedin a direction at substantially right angles to the flange 80. Various other designs of these mounting brackets are contemplated within the scope of the present invention.
I shall not show all possible variations in the design of the mounting bracket, but to illustrate some variations I have shown in Figure 9 the openings 59a and 64a as spaced in a direction generally parallel to the mounting flange 80a, and in Figure 10 I have illustrated a further modification in which the outer periphery of the mounting flange 80b of the bracket 58b is of generally circular form and provided with a peripheral flange at 85 and with mounting openings 86 shown positioned diametrically opposite each other. Various other forms of mounting may be provided, and it is to be understood that various forms of porting and drilling of the pilot burner tip l2 at l3 are contemplated within the scope of the present invention.
I do not intend to be limited to the precise details shown or described.
I claim:
