MODES OF CARRYING OUT THE INVENTION While the various features of this invention are illustrated and described below as being particularly adapted to provide a hot water heater which has a fuel control device and a hot water tank construction thereof of particular configurations, it has It is to be understood that the various features of this invention may be used separately or in various combinations thereof to provide other types of hot water heaters as desired. Therefore, this invention is not to be limited to only the embodiments illustrated in the drawings, because the drawings are used merely to illustrate one of a wide variety of uses of this invention.

Referring now to Figure 1, a new hot water heater of this invention is generally indicated by the reference numeral 20 and consists of a tank construction 21 for hot water having a wall means 22 provided with an opening means 23 therethrough and an embossed ring 24 carried by the wall means 22 and which it has an opening means therethrough which is generally indicated by the reference numeral 25 and which is arranged in aligned relation with the opening 23 of the wall area 22. The water heater 20 consists of a device for fuel control 26 of this invention having a single rod construction 27 provided with a tubular portion or means 28, Figure 3, arranged in the opening means 26 of the raised ring 24 and interconnected to the opening means 25 so as to be carried by the wall means 22 by means of which the entire fuel control device 26 is carried, this way, by the wall means 22. The particular type of interconnection of the tubular means 28 of the rod portion 27 with the opening means 25 of the raised ring 24 ee of the single axial type of pushing in completely, described and claimed in Katchka's North American patent, No. 5,261,438 that is mentioned above so that this North American patent is being incorporated in this description by this reference thereto. The opening means 25 of the embossed ring 24 is illustrated in the best manner in Figure 4 and consists of a rod connection 29 consisting of a cylinder or tube formed of metallic material and having opposite ends 30 and 31 and having has an outer peripheral surface means 32 and an inner peripheral surface means 33, the end 31 of the rod connection 29 having the external peripheral means 32 of surface thereof provided with outer cords 34 which are adapted to be threaded in a internally threaded opening 35 of the raised ring 24 so that it is carried by it as illustrated. The rod connection 29 has an internally beveled surface 36 which leads to the inner peripheral surface 33 at the end 30 thereof and the inner peripheral surface 33 is interrupted by a first annular groove 37 and a pair of equal annular grooves 38 which are they are spaced from each other, the annular grooves 38 annular sealing members 39 at 0 therein in a manner well known in the art for sealing purposes with 0-rings so that the portions of the rings 39 at 0 extend nominally towards in radially beyond the inner peripheral surface means 33 for its sealing function as will be evident below. The annular groove 37 in the rod connection 29 consists of an axial securing means for the opening means 25 of the raised ring 24 and is given the reference number 40 so that it is hereinafter referred to as the axial securing means. 40 for the opening means 25 of the raised ring 24 or the axial securing means 40 for connecting the rod 29 as the case may be. The unique stem construction 27 of this invention for the fuel control device 26 has a flange means 41 which is fixed to a housing means 42 of the fuel control device 26 by the threaded fastening members 43. , Figure 5, in a manner conventional in the art and the tubular portion or means 28 of this invention is interconnected to flange means 41 in the manner described below so as to protrude outwardly from the fuel control device 26. tubular means 28 has an outer peripheral surface means 44 and has opposite ends 45 and 46, the tubular means 28 having a stepped opening means 47 which passes therethrough and which defines an internally threaded portion 48 in which a externally threaded portion 49 of a conventional sensing unit 50 of rod and tube temperature so as to operate the fuel control device 26 in a manner conventional in relation to the temperature being sensed by enlarged end 51 of the unit 50 to be arranged in a chamber 52 containing water from the construction of the tank 21 for hot water in a conventional manner when the fuel control device 26 it has a tubular portion 28 of the rod construction 27 of the limb disposed in the opening means 25 of the raised ring 24 in the manner discussed below. The operation of a device for fuel control is well known in the art. For example, see the North American patent of Katchka and others, No. 4,872,830 mentioned above with which this patent is being incorporated to this description by this reference thereto. In this way, a further description of the operation of the fuel control device 26 is not necessary to control the heating of the tank construction 21 for hot water. The peripheral outer surface medium 44 of the tubular means 28 of the rod construction 27 of the fuel control device 26 is interrupted by an annular groove 53 in which the inner portions of a split metal ring of brooch 54 are arranged in a polygonal shape. so that the outer portions 54 'of the rim of the ring 54 normally extends radially outwardly beyond the peripheral outer surface medium 44 of the tubular means 28 due to the natural elasticity of the ring 54 in a manner well known in the art. However, the outer portions 54 'of the rim of the ring 54 are adapted to be provided with cams into the groove 53 so that the outer peripheral edges 54' of the ring 54 are substantially coplanar with the surface medium 44 of the tubular medium. 28 as will be apparent below although the natural elasticity of the ring 54 is tending to extend the ring 54 actually outward to its normal condition illustrated in Figure 5 in which the outer peripheral edges 54 'of the ring are extending beyond the peripheral outer medium 44 of surface of the tubular means 28. The ring 54 consists of an axial securing means for the construction of the rod 27 and is also given the reference number 55 so that it will be referred to later as the axial securing means 55 for the construction of rod 27 of the fuel control device 26. The flange means 41 of the rod portion 27 of the device The fuel control device 26 has a projection 56 adapted to cooperate with a notch 57 formed in the end 30 of the rod connection 29 as illustrated in Figure 12 to guide the rotational fuel control device 26 with the power connection. stem 29, the end 30 of the rod connection 29 having two such notches 57 disposed 180 ° relative to each other although only one of the notches 57 cooperates with the projection 56 at any one time as is evident from the drawings. From the foregoing, it can be seen that it is a relatively simple method of the invention set forth in the North American Katchka patent, No. 5,261,438 which is mentioned above to form a fuel control device 26 of this invention to have the medium axial locking means 55 and to form a rod connection 29 so as to have an axial securing means 40, cooperating the axial securing means 40, the axial securing means 55 and 40 cooperating together to effectively interconnect the control device for fuel 26 to the opening means 25 of the raised ring 24 of a tank construction 21 for hot water in a unique manner through the simple axial movement of the valve device for fuel control 26 with respect to the tank construction 21 for hot water rather that through a rotary threaded movement of the fuel control device 26 with respect to the construction tank 21 for hot water as the other previous assembly operations that are known. In particular, the manufacturer of a tank construction 21 for hot water initially threads the rod connection 29 into the threaded opening 35 of the raised ring 24 to the p >The arrangement illustrated in Figure 4 so that the jaws 57 at the end 30 of the stem connection 29 are arranged in a vertically aligned relationship to subsequently orient the fuel control device 26 accordingly appropriately rotatably thereto. After that, the fuel control device 26, together with its temperature sensing unit 50 is assembled to the tank construction 21 by means of merely moving the fuel control device 26 in the direction of the arrow 58 in Figure 2 so that not only the temperature sensing unit 50 extends through the opening 33 of the rod connection 29, through the aligned opening 23 of the wall 22 and to the chamber 52 of the tank construction 21 for hot water, but also between the tubular means 28 of the rod construction 27 of the fuel control device 26 axially in the opening 33 of the rod connection 29 and when the peripheral edges 54 'of the ring 54 are coupled to the surface of cams 36 at the end 30 of the rod connection 29, the size of the ring 54 is reduced to insert it into the annular groove 53 of the tubular means 28 to allow the same for the opening 33 of the rod connection 29 is subsequently aligned axially with the annular groove 37 thereof so that the ring 54 can be extended radially outwards by means of the natural elasticity thereof to be locked in the groove ring 37 and thereby interconnect the rod construction 27 to the opening means 25 of the raised ring 24 as illustrated in detail in FIG. 3. At the same time that the ring 54 extends radially outwardly to the connecting rod slot 37. , the projection 56 of the rod construction 27 is received in the engaging notch 57 of the rod connection 29 with which the valve device for fuel control 26 is now completely interconnected to the tank construction 21 for hot water in FIG. its operating position with it.

Also, it can be seen that the notch 57 orienting the rod connection 29 requires a vertical alignment of the projection 56 of the rod construction 27 so that the fuel control device 26 is oriented appropriately rotationally relative to the means of p > ared 22 of the construction of tank 21 for hot water. During such an assembly step of inserting the rod construction 27 of the fuel control device 26 into the opening 33 of the rod connection 29, the sealing members 39 with a ring at 0 are against the outer peripheral means. 44 of surface of the tubular means 28 to prevent leakage of water from the chamber 52 into the opening means 25 of the raised ring 24 in a well known manner of the ring sealing technique at 0. Although it is preferred to have the means of securing or axial 55 of the rod construction 27 completely aligned with the axial securing means 40 of the rod connection 29 before an end surface 56 'of the projection 56 of the rod construction 27 engages against the cooperating closed end 57 'of the notch 57 of the rod connection 29 and / or before the end 30 of the rod connection 29 abuts the surface 59 of the flange means 41 of the vastag construction. or 27 so as to allow neglect of the path of the rod construction 27 to the rod connection 29, it is to be understood that such leveling of one or more surfaces on the rod construction 27 and the stem connection 29 could take place at the same time that the snap ring 54 of the rod construction 27 is aligned with the slot 37 of the rod connection 29 since the width of the slot 37 can be selected so that the split ring 54 is aligned with an amount sufficient in slot 37 to allow engagement with it so that the tolerance admission could be provided by the width of the slot 37 rather than ensuring that the surfaces of the rod construction 27 and the rod connection 29 are not leveled before there is complete alignment of the ring 54 with the slot 37. Since the fuel control device 26 of this invention is put in place in a purely axial manner in the connection In this manner, in the previously established manner and it is not required to rotate as the above known threading operations, various conduit means may be interconnected to the housing means 42 of the fuel control device 26 before it is assemble the same to the construction of tank 21 for hot water. For example, it can be seen in Figure 2 that the burner means 60 for the tank construction 21 for hot water has its conduit means 61 for supplying interconnected fuel to an outlet coupling 62 of the fuel control means 26 before the fuel control device 26 is assembled with the tank construction 21 for hot water. In this way, the fuel control device 26 can be tested with the burner means 60 at a location remote from the tank construction 21 for hot water so as to ensure that the fuel control device 26 and / or the burner means 60 are operating properly before they are assembled to the tank construction 21. Of course, the main burner means and its conduit means for supply as well as its thermoelectric torque means for the burner means 60 can be preassembled also to the device for controlling fuel 26 in the same way and with the same purpose although such a structure is not illustrated in figures 1 V 2. In this way? it can be seen from Figures 1 and 2 that the fuel control device 26 moves axially to the opening means 25 of the raised ring 24, the burner means 60 and its means 61 for fuel limitation 61 are moved axially therewith to an appropriate position thereof in a heating chamber 63 of the tank construction 21. In this way, it can be seen that the method for manufacturing the water heater allows a manufacturer to screw the rod connections 29 into the threaded openings 35 of the raised rings 24 of the constructions of the water heater tank 21 until they are disposed in the predetermined positions of the heaters. same, wherein the grooves 57 are disposed substantially vertically in relation to aligned and then easily assembled the fuel control devices 26 thereto only by pushing axially inwardly over such fuel control devices 26 at the respective rod connections 29 until the axial clearance means 55 of the devices Fuel control 26 are aligned with the axial securing means 40 of the rod connections 29 to positively interconnect the fuel control devices 26 to the wall means 22 of the respective tank constructions 21 to form water heaters 20. When it is desired to disassemble a fuel control device 26 from its hot water tank construction 21 such as in the field where the initially installed fuel control device 26 needs to be replaced with a similar fuel control device 26 or other unit similarly, service personnel disconnect all means of pipe, etc. which are interconnected to the housing means 42 of the fuel control device 26, as illustrated in FIG. 10. In this way, the fuel control device 26 is now adapted to be removed in a normal manner and the personnel of the service rotates the housing means 42 to unscrew that fuel control device 26 from the threaded openings 35 of the strut 24; the rod construction 27, by the actuation relation of the projection 56 of the flange means 41 in the cooperating groove 57 of the rod connection 29, as illustrated in FIG. 11, unscrews the rod connection 29 therein from the threaded opening 35 of the raised ring 24, thereby the removed fuel control device 26 is in the condition illustrated in figures 11 and 12. In this way, that service person could then screw the threaded portion of a valve unit conventional fuel control or screw a fuel control valve device 26 of this invention which has the rod connection 29 assembled thereto, in the manner illustrated in figure 11, back into the threaded opening 35 of the strut 24 as in the prior known operation of screwing by turning the fuel control valve device 26 or other units. Of course, if that service person replaces the fuel control valve 26 and the separate rod connection 29 thereof, that service person has the option of screwing the rod connection 29 into the threaded opening 35 of the rod 24. and then axially inserting the rod construction 27 of the new control valve device 26 therein, in the manner illustrated in Fig. 2, or assembling that rod connection 29 to the rod construction 27 of the new fuel control device 26, as illustrated in FIGS. 11 and 12 before screwing the interconnected rod connection 29 into the threaded opening 35 of the rod 34.

In any case, it can be seen that a service person who is not familiar with the initial assembly operation of the fuel control devices 26 with the hot water tank constructions 21 during the initial manufacturing stage of the member will remove it. fuel control valve device 26 in the field in exactly the same manner as the service person who has removed a previous known fuel control device from a hot water tank to replace it with a new control valve device of fuel in the usual way. As stated above, one of the features of this invention is to interconnect only the tubular means 28 to a flange means 41 to form the rod construction 27 of this invention so as to operate in the previously exposed manner. Therefore, reference is now made to the Figures 6 and 7 where it can be seen that the flange means 41 has an aperture means 64 that passes through opposite sides 65 and 66 of a portion 67 thereof with those opposite sides 65 and 66 being substantially planar. The end 46 of the tubular means 28 cooperates with an intermediate portion of larger diameter 68 thereof to define an annular flat shoulder 69 which is adapted to rest against the surface 65 of the petaine means 41 when the end 46 is fully inserted in the opening 64 of the flange means 41, the end 46 projects beyond the surface 66 when the shoulder 69 of the tubular means 28 bears against the side 65 of the portion 67 of the flange means 41. Then, the end 46 is pressed against the surface 66 of the middle flange 41 for retaining or positively securing the tubular means 28 to the flange means 41. For example, the end 46 of the tubular means 28 can be turned over and rolled against the surface 66 of the portion 67 of the flange means 41 by any suitable apparatus of bearing or stamping so that the turned-over portion 70 of the end 46 of the tubular means 28 is pressed against the side 66 of the flange means 41 while the shoulder means 69 of the tubular means 28 is in full engagement with the planar surface 65 of the flange means 41, as illustrated in FIG. 8. In this regard, it can be seen that it is a relatively simple method of this invention to interconnect a tubular means 28 to a means of tab 41 p > to form the rod construction 27 of this invention. Although it has been described above that the tubular portion 28 has the axial securing means 55 to allow it to be secured to a rod connection 29 by means of a simple axial thrust operation as previously described, it is understood that the tubular member 28 can be suitably dimensioned and be provided with external threads that could cooperate with internal threads 35 of strut 24, by rotating the fuel control device for having such external thread means of the stem portion thereof in the previously known screwing operation. However, it is believed in accordance with the teachings of this invention that it would be convenient to provide mechanical closure of the tubular means with the flange means 4.1 during the stamping operation to ensure non-rotational movement between the tubular means and the flange means during such operation. of stamping. For example, reference is now made to FIGS. 13 and 14, where another fuel control device of this invention is generally indicated with the reference number 26A, and parts thereof similar to the parts of the fuel control device 26 and construction of the hot water tank 20, are indicated with the same reference numbers followed by the reference letter "A". As illustrated in Figure 13, it can be seen that the flange means 41A has the opening 64A that is formed therein, is provided with a caged arrangement that is generally indicated with the reference number 71 and comprises a plurality of projections 72. which extend radially towards the opening 54A, and have recesses 73 therebetween so that when the cooperating end 46A of a tubular means 28A is stamped into position to form the turned portion 70A thereof, described above in the same manner, parts of the tubular means 28A enter the recesses 73 of the encapsulated portion 71 of the flange means 41A to mechanically close therewith and thereby prevent rotational movement between the tubular means 28A and the flange means 41A. Although the tubular means 28A which is attached to the flange means 41A in the manner described above could have axial securing means 55 thereon to operate-in the same manner as in the rod construction 27, as described above, the particular tubular means 28A illustrated in Figure 10 has an externally threaded portion 74 for screwing directly into the internal threads 35A of a strut 24A mounted to the wall 22A of a hot water tank construction 21A in a conventional manner having the device of fuel control 26A rotated in the proper direction to provide said screwing operation. Although the rod construction 27 described above can be formed of any suitable material, a working mode thereof has the flange means 41 stamped from hot rolled steel which is approximately 0.34 c thick before being stamped, and the opening 64 formed therethrough has a diameter of about 1.85 crn. Said working method has the tubular means 28 formed of hard medium brass No. 360 with the intermediate portion 68 thereof with a diameter of approximately 2.1 cm while the end 30 has a diameter of approximately 1.85 crn. The annular groove 44 of the tubular means 28 is approximately 0.10 crn in width. Said working method of the tubular rod connection 29 is also formed of hard medium brass No. 360 which is approximately 2.5-0.3 crn in diameter and the annular groove 37 thereof has a width of approximately 0.09 cm. NeverthelessIt is understood that the dimensions and materials set forth above for one of the working modes of this invention may have any suitable dimensions and any suitable materials. In this way, it can be seen that this invention not only provides a new fuel control device and a new method of manufacturing the same, but also this invention provides a new part for said fuel control device and a new method for producing said fuel control device. new part Although the presently preferred forms and methods of this invention have been illustrated and described as required in accordance with the patent statute, it is understood that other forms and steps of the method may be used and still fall within the scope of the appended claims wherein each claim states what is believed to be known in each clause before this invention in the portion of each claim that is disposed before the terms "improvement" and establishes what is believed new in each claim in accordance with this invention in the portion of each claim that is disposed after the terms "improvement" it is believed that each claim expresses a novel, useful and non-obvious invention within the scope of the Patent Statute.
