Definitions

  • the present invention relates to gas-burning apparatus in general, and more particularly to an attachment which may be put to use in gas ranges, in gas-burning furnaces, in gas-burning heaters, in gas-heated boilers and in many other types of gas-heated or gas-burning appliances and apparatus. Still more particularly, the invention relates to an attachment which delivers, ignites :and controls the flow of gaseous fuel to such apparatus.
  • Another object of the invention is to provide an attachment of the just outlined characteristics wherein the escape of gaseous fuel is prevented in a fully automatic way as soon as the flame on the burner nozzle is can tinguished, either accidentally or on purpose, wherein the position of the igniter with respect to the burner nozzle is fixed in such a way that the gas-igniting portion of the igniter is in optimum position with reference to the gas-discharging portion of the burner nozzle, and wherein the heat sensitive portion of a customar thermoelectric current generator which automatically prevents escape of non-ignited gases is mounted in such a way that it assumes an optimum position with reference to the gas-discharging portion of the burner nozzle.
  • An additional object of the invention is to provide an improved supporting member for the burner nozzle, igniter and thermoelectric current generator of an attachment which exhibits the above outline-d characteristics.
  • a further object of the invention is to provide a supporting member which aifords access to all or nearly all of the parts supported thereby without necessitating separation of the supporting member from the wall or another element of the apparatus in which the attachment is put to use.
  • a concomitant object of the invention is to provide a supporting member which may be detached from the apparatus without necessitating even partial dismantling of the apparatus.
  • Still another object of the invention is to provide a supporting member which is constructed in such a way that it automatically holds the burner nozzle, the igniter and the generator in requisite position as soon as these parts are properly received therein but which nevertheless allows for adjustments of at least one such part in the event that the ignition of gases or heating of the generator is not satisfactory when the apparatus is in actual use.
  • a further object of the invention is to provide an attachment wherein the igniter, the burner nozzle and/or the generator may be detached and reinserted as often as desired without affecting the accuracy of their positioning with reference to each other and wherein each of these parts may be detached and reconnected either by hand or with the help of very simple n dil available tools.
  • one feature of my invention resides in the provision of a gas-burning or 3,200,875 Patented Aug. 1?, 1965 ice gas-heated apparatus comprising a wall one side of which is more readily accessible than the other side, thereof and which is provided with an opening, an attachment including a one-piece supporting member having a substantially plate-like base adjacent to the one side of the wall so as to extend across the opening and having a readily accessible outer side, and fastener means detachlably securing the base to the one side of the wall.
  • the supporting member comprises a series of holders in the form of nipples which are integral with the base and which extend through the opening and beyond the other side of the wall, and the attachment further comprises a burner nozzle which is preferably detachably received in one of the nipples, an igniter which is preferably detacha'bly received in a second nipple and whose gasigniting portion is closely adjacent to the gas-discharging portion of the burner nozzle, and a thermoelectric current generator which is preferably detachably received in a third nipple and :a heat sen-sitive portion of which is closely adjacent to the gas-discharging portion of the burner nozzle.
  • At least the igniter and the current generator will be normally arranged in such a way that each thereof is accessible through the outer side of the base and the arrangement is such that, when properly received in their respective nipples, the igniter and the generator will automatically assume optimum positions with reference to the gas-discharging portion of the burner nozzle to make sure that the gas discharged by the burner nozzle will be ignited :as soon as the i-gniter is operated and that the generator will send an electric current as soon and as long as the gas is burning.
  • nipples may be provided with internal threads but, if desired, the respective parts may be retained therein in bayonet lockfashion or in another suitable way.
  • FIG. 1 is a side elevational view of the attachment
  • FIG. 2 is a top plan view of the attachment as seen from the hardto-re-ach inner side of a supporting wall which constitutes a component part of the gas-burning apparatus wherein the attachment is put to use;
  • FIG. 3 is a section asseen in the direction of arrows from the line III-J11 of FIG. 2.
  • FIG. 1 there is shown an attachment which is especially suited for use in a gas-burning or gas-heated apparatus such as a gas range, a gas-heated boiler, a continuously heating gas furnace or the like. It is assumed that the attachment is used ina gas range or a similar appliance and that it is secured to the readily accessible outer side 2012 of a wall 20 which is the rear wall of the range.
  • This attachment includes a burner here shown as a nozzle 10, an igniter here shown as a spark plug 11, a conventional thermoelectric current generator 12, and a one-piece supporting member 13 which comprises speciallyconfigurated tubular holders or nipples provided with sockets for reception of the parts 10, 11 and 12.
  • the arrangement is such that the burner 10 is accessible from the inner side 20a of the wall 20 and that the igniter 11 and generator 12 may be reached from the outer side 2% of this wall.
  • the outer side 2012 is mor readily accessible than the inner side 20a.
  • the supporting member 13 further comprising a carrier in the form of a plate-like base 18 having at its inner side a slightly raised oval platform 18a which fits into a complementary opening 200 of the wall 20.
  • the base 18 extends across the opening 200 and the platform 18a is surrounded by an annular sealing element 21 of elastic material which abuts against the outer side 20b of the wall 20 around the opening 200.
  • the base 18 is provided with two laterally extending projections or lugs 19 which are detachably secured to the outer side 2012 of the wall 20 by screws 22 or by similar fasteners.
  • the heads (not shown) of the screws 22 are located at the outer side 18b of the base 18 so that an operator may rapidly detach the supporting member 13 merely by withdrawing the screws 22 and by thereupon withdrawing the platform 18a from the opening 20c.
  • the supporting member 13 further comprises a first tubular holder or nipple which extends through the opening 200 and beyond the inner side a of the wall 20 and which is provided with internal threads to mate with external threads provided on the burner 10.
  • the axis-of the nipple 15 is substantially perpendicular to the general plane of the base 18.
  • the burner 10 is formed with a central bore 10a which communicates with three inclined discharge orifices 10b, 10c, 10d and with a bore 23 provided in the base 18.
  • the orifices ltlb-ltld are provided in the gas-discharging end portion of the burner 10 which extends beyond the open end of the nipple 15.
  • the burner 10 is held against rotation by a lock nut 24 which bears against the end face of the nipple 15.
  • the axial position of the burner 10 may be adjusted upon loosening of the nut 24.
  • the nipple 15 is aligned with a second tubular holder or nipple 25 which extends beyond the outer side 18b of the base 18 and which is provided with internalthreads to take an externally threaded annular plug 26 connected to the discharge end of a gas supply conduit 27 which contains a safety valve 28.
  • the valve 28 is of known design and is operated either manually by a pushbutton 29 or automatically by the thermoelectric current generator 12 in a manner which will be described later.
  • thermoelectric current generator 12 there is a packing 30 which is accommodated in the socket of the nipple 25 and which is compressed by the plug 26 to prevent escape of gas at the outer side of the supporting member 13.
  • the operative connection between the safety valve 28 and the thermoelectric current generator 12 comprises a conductor 31 one terminal portion of which is electrically connected with the generator 12 by means of a nut 32.
  • a third tubular holder or nipple 16 of the supporting member 13 extends through the opening 200 and beyond the inner side 20a of the wall 20 and is provided with internal threads to take an externally threaded annular plug 33 which causes a boss 11a on the central portion of the igniter 11 to abut against the inwardly bent annular edge portion 16a at the open end of the nipple 16 and to thereby provide a fluidtight seal between the socket of'the nipple 16 and the space at the inner side 20a of the wall 20.
  • the socket of the nipple 16 is open at the outer side 18b of the base 18 so that an operator may engage the rear end of the plug 33 by means of a suitable tool in order to remove the igniter 11 for the purpose of inspection or replacement.
  • the plug 33 is formed with slots 33a which may receive the tip of a suitable tool.
  • a similar slot 10;: is provided in the gasdischarging portion of the burner 10 so that it may take the tip of a screwdriver which serves to unscrew the burner from the socket of the nipple 15.
  • a fourth tubular holder or nipple 17 of the supporting member 13 is similar to the nipple 16 and serves to receive the externally threaded central portion of the thermoelectric current generator 12 so that the heat-sensitive tip 12a of the generator is located between the orifices 10c, 10d, see FIG. 2.
  • the tip 12a extends beyond the open end of the nipple 17 and is closely adjacent to the gas-discharging portion of the burner 10.
  • the generator 12 may be reached from the outer side 1812 of the base 18 because the outer end of the socket defined by the nipple 17 is open and because a portion of this generator extends beyond the outer side 18a.
  • the axis of the nipple 16- is inclined with reference to the nipple 15 so that the gas-igniting electrode 11b of the igniter 11 extends beyond the open end of the nipple 16 and into close proximity of the orifice 10b in the gas-discharging portion of the burner 10.
  • the arrangement is such that, when the attachment is fully assembled, the electrode 11b automatically assumes an optimum position with reference to the orifices 10c, 10d whereby any likelihood of improper operation is avoided at all times.
  • a conductor 34 connects the igniter 11 with a suitable source of electrical energy, not shown. The outer end portion of the igniter 11 extends beyond the outer side 18a of the base 18.
  • the pushbutton 29 When the operator desires to use the gas range, the pushbutton 29 is depressed so that a stream of gas flows toward the orifices 10b-10d, and the operator simultaneous-ly completes the circuit of the igniter 11 whereby the electrode 11b ignites the gas stream which escapes through the orifice 10b.
  • the resulting flame F ignites the gas streams which flow through the orifices 10c, 10d so that the tip 12a is heated and the generator 12 sends a weak current to a suitable electromagnet which is accommodated in the safety valve 28 and which is thus energized to automatically retain the valve 28 in open position as long as the flames at the orifices 10c, 10d heat the tip 12a.
  • the one-piece supporting member 13 may be made of metallic or synthetic plastic material and one of its important advantages is found to reside in that the cooperating parts 10, 11, 12 of the improved attachment are automatically located in requisite position with refer ence to each other so that there is no danger of uncon trolled escape of gas once the attachment is secured to the wall 20. Another important advantage of the attachment is seen in that the member 13 may be rapidly attached to or disconnected from the outer side 28b of the wall 20 and that nearly all of its parts may be detached even if the supporting member 13 remains secured to the wall.
  • the attachment of my invention may be modified in such a way that the burner 10 is accessible from the outer side 18]: of the base 18 and that the igniter 11 (which is shown in the form of a spark plug) may be replaced by a different igniter (for example, one wherein the gasigniting electrode 11b is replaced by a hot wire) without in any way departing from the spirit of this invention.
  • the improved attachment is of particular advantage in such types of gas-burning appliances and apparatus wherein the interior of the apparatus is normally hard to reach without partial or complete dismantling of its parts.
  • the boiler may be installed in a normally locked room and the attachment may be reached through an aperture or window provided in one wall of the boiler room so that the operator need not enter the boiler room when he desires to gain access to the burner, igniter and/or generator of the improved attachment.
  • the positioning of the igniter and generator with reference to the burner is of utmost importance because the apparatus is normal- 1y locked and the operator must rely on the supporting member to hold these parts in requisite position.
  • presently used gas-heated or gas-burning apparatus are not provided with one piece supporting members which can automatically retain the igniter and/ or the thermoelectric current generator in optimum position with respect to the burner.
  • the burner of my improved attachment serves as a means for igniting one or more main burners of the apparatus, i.e., this burner may perform the function of a pilot burner.
  • the base 18 of the attachment may be mounted in a horizontal, vertical or otherwise inclined plane without affecting the operation of parts which are mounted on the supporting member.
  • the feature that the wall 24 must be formed with a single opening c is of particular advantage when the improved attachment is to be installed in a conventional gas-burning or gasheated apparatus. Also, this single opening 20c may be sealed by a single washer or similar sealing element.
  • the supporting member 13 and the burner 10 may be provided with two or more gas-conveying bores of different diameters so that the attachment may be used in connection with different types of gaseous fuel.
  • the operator merely seals one or more bores and permits the fuel to flow through such bores whose diameters are suflicient to convey requisite quantities of a given fuel.
  • the burner is normally provided with two or more sets of gas-discharging orifices.
