Definitions

  • the present invention relates to cigarette lighters of the type utilizing gaseous fuel and is directed to specific improvements in devices of this character.
  • a seal or gasket In a cigarette lighter operating on gaseous fuel and wherein the burner outlet orifice is formed in a pivoting lever adapted, when manually operated, to free the gasoutlet orifice, a seal or gasket must be provided to avoid any lateral escape of gas, thereby forcing the gas to flow only through the burner orifice.
  • the present invention is concerned with an improved arrangement whereby this or any seal or gasket can be dispensed with.
  • the invention consists in substituting for the conventional gasket or seal one or more labyrinth-forming baffles comprising at least one groove closed on itself and concentric with the gas-outlet orifice, this groove having a blank engageable by a lip of corresponding contour also continuous and closed on itself.
  • baffles are concentric with each other with, of course, the same arrangement for the lips co-acting therewith.
  • grooves or grooves may be formed either on the fixed head of the lighter (in which case the corresponding lip or lips is or are formed on or carried by the pivoting control lever, or in said lever, the lips being formed in or carried by the body.
  • These grooves and lips may have a circular or polygonal contour.
  • FIG. 1 illustrates the device in the closed position
  • FIG. 2 shows the same device in its open position.
  • the reference numeral I designates the cover formed with a projecting pushdown portion 2 and the burner outlet orifice 3, this lever I being fulcrumed about a fixed pivot pin 4 carried by the body or head of the lighter 5; a spring 6 constantly urges this lever 1 toward its closed position in which a valve-forming washer 7 is pressed against the seat-forming outlet end of the gas-outlet passage 8.
  • At least one relatively deep groove 9 closed on itself is formed in the head 5, and the lever 1 comprises the same number of lips 10 also closed on themselves and engaging (i.e., being received in) these grooves.
  • valve-forming washer 7 is unseated to permit the escape of gas through the burner orifice 3.
  • this gas flows preferentially and only through the burner orifice 3 due to the lower resistance encountered for this flow.
  • one of said members is formed with a plurality of concentric grooves open in the direction of the other member and each extending endlessly around said orifice; said other of said members is formed with a respective lip received in each groove between the flanks thereof, said lips projecting in the direction of said one of said members and extending endlessly around said orifice to form a labyrinth seal with said flanks of said grooves, said lever including a burner outlet orifice; and a valve-forming washer located between said burner outlet orifice and said
