Definitions

  • ABSTRACT An electromagnetic ignition device for fuel Int. Cl H02k 35/00, fluids and the like, includes circuit means which is mechani- HOlt 13/42 cally actuatable for producing an electric spark.
  • a plurality of Field of Search 317/81, 96, mechanical actuating means are provided each of which is 92, 379; 431/255; 310/26, 103-104, 36; operatively associated with the circuit means and individually 200/21-2, 30-1 operable for effecting actuation thereof.
  • the present invention relates generally to the actuation of 5 ignition devices, and more particularly to mechanical actuation of electromechanical ignition devices.
  • Electromechanical ignition devices are used in many applications, and by way of example reference is made totheir employment in conjunction with gas burners in gas furnaces, kitchen ranges and the like where they are used to ignite fuel issuing from the respective burner.
  • Such applications for devices of the type under discussion are quite widespread now and the devices are usually manufactured as complete units which are provided with housings and actuating means adapted to the respective circumstance of use.
  • one type of actuating means may be necessary if the device is to be employed with a kitchen range where the ignition of the fuel issuing from the burner or burners is possible in close proximity with the burners, that is where the operator can closely approach the range, and another type of actuating means, for instance a remote actuating means, may be desirable or necessary for use with gas furnaces, for instance to avoid the necessity to negotiate basement stairs if the furnace is installed in the basement of a house.
  • actuating means for instance a remote actuating means
  • a more particular object of the present invention is to provide such an ignition device of the type under discussion which can be used in a variety of different applications without requiring special construction and/or adaptation.
  • an object of the present invention to provide an ignition device of the type under discussion which has a plurality of mechanical actuating means each of which is individually operable for effecting actuation of the device.
  • an electromagnetic ignition device for fuel fluids and the like which comprises circuit means mechanically actuatable for producing an electric spark, and a plurality of mechanical actuating means each operatively as sociated with the circuit means and each individually operable for effecting actuation of the circuit means.
  • FIG. 1 is a somewhat diagrammatic section of an ignition device according to the present invention, taken on the line H of FIG. 2;
  • FIG. 2 is a side-elevational view of the ignition device shown in FIG. I;
  • FIG. 3 is a bottom view of the device shown in FIGS. I and 2.
  • l have illustrated a make-and-break type of electromagnetic ignition system, including a yoke l, a coil 2, a magnet 3 and an armature 5 turnable about an axis 4.
  • a leaf spring 6 engages the armature 5 whose free end abuts against the coil 2, and the entire arrangement is located within a housing 7.
  • my device has a plurality of mechanical actuating means for providing actuation of this ignition circuit whose construction and operation is generally well known to those skilled in the art and is therefore not believed to require detailed description. It may suffice to point out that pivoting of the armature 5 about the axis 4 in a sense establishing a gap 9 (see FIG. 1) between the free end of the armature 5 and the coil 2, will result in a mechanical and magnetic interruption of the magnetic circuit against the holding force of the magnet 3 and in a conventional production of a spark in the spark gap between the electrodes 100.
  • actuating means 8 comprises a shaft 83 mounted in the housing 7 for movement in direction of the arrow in FIG. 1, either by having an operator exert a push on the end portion 81 which constitutes a pushbutton, or by exerting a pull on the knob 82 associated with the other end of the shaft 83.
  • An actuating portion 84 is adjustably mounted on the shaft 83 within the confines of the housing 7; it is here illustrated as a nut or internallythreaded washer or the like which is threadedly mounted on an externally threaded portion of the shaft 83 so that it can be adjusted lengthwise of the latter. As illustrated in FIG.
  • FIG. 1 where a rotary shaft 10 is illustrated (compare also FIG. 2) which has mounted thereon an eccentric 11 so that the latter will turn as the shaft 10 is turned.
  • the eccentric 11 abuts against the leaf spring 6, as shown in FIG. 1.
  • Turning of the rotary shaft 10 will result in tensioning of the leaf spring 6 in the same manner and with the same results as already described with respect to the employment of the actuating means 8.
  • turning of the rotary shaft 10 may be accomplished in several ways. Firstly there is provided a knob 20 fixed to one end of the rotary shaft 10 which extends outwardly from the housing 7 (see FIG. 2). At the other end of the rotary shaft 10, which also projects outwardly of the housing but at a side thereof opposite the knob 20, I have provided a pulley 22 which is connected with the shaft 10 in such a manner as to rotate therewith but not relative thereto. How this is done is well known, and one exemplary possibility is the use of a key connection between the shaft 10 and the pulley 22. A rope 23 or analogous elongated flexible actuating member may be placed about the pulley 22 and permits remote actuationof the device simply by exerting a pull upon the rope 23.
  • a further actuating means is provided by forming one axial end of the pulley 22, identified in FIG. 2 with reference numeral 221, with an annulus of radial teeth as illustrated.
  • An actuating lever 21 is provided with a surface 211 having a, mating annulus of teeth which engage with the teeth on the axial end face 221 of the pulley 22; a screw or analogous connecting means 24 serves to hold the teeth on the faces 221 and 211 in engagement and of course the lever 21 can be turned to any desired position with respect to the pulley 22 prior to being fixed immovably in this position with the screw 24. Pressure on this lever 21 will then also effect rotation of the shaft and tensioning of the leaf spring 6 via the eccentric 11.
  • this device can be used for the ignition of gasburners on kitchen ranges whether either the pushbutton 81 or the knob 82'will be readily accessible to the fingers of an operator.
  • the device may be used for use with a hot water installation which is to be activated and deactivated periodically at the will of the user and where, depending upon the positioning of the device shown in the drawing which may be dictated by space requirements, structural features of the equipment with which the device is being used, or similar considerations, the knob 20 may be used to turn the rotary shaft 10, the lever 21 may be employed or the shaft 10 may be turned by pulling on the rope or analogous means 23.
  • an electromagnetic ignition device in combination, a housing; an ignition system mounted in said housing and including a magnet, an ignition coil, a yoke with one arm attached to one end of said magnet and with the opposite arm extending through said ignition coil, and having an armature normally completing with said magnet, and yoke an electromagnet circuit and being movable to an energizing position interrupting said circuit so that. the same produces an electric spark; and mechanical actuating means carried by said housing, including an arm fast with said armature and deflectable from a normal rest position to an operating position in which it displaces said armature to said energizing position, a linearly,
