Outdoor gas cooking appliance

Claim 2

A semiautomatic timed shut-off valve assembly adapted for use in a gas grill, comprising: normally closed valve means including fuel inlet means and fuel outlet means, said fuel outlet means being connected to a valve for controlling fuel flow to a gas burner; a first manually actuatable actuator for opening said valve means, said first actuator including a tang portion extending transversely therefrom; a second separate manually actuatable actuator spaced from said first actuator; and a timed means being actuatable by said second actuator, said timed means including a pivotal arm, said tang portion including a surface thereon for engagement with said pivotal arm, said pivotal arm being pivoted for engaging said surface of said tang portion for causing said valve means to remain in said open position for a variable preset time and for thereafter releasing said first actuator to permit said valve means to close, said second actuator being actuatable only after the actuation of said first actuator, said second actuator actuating said timed means when actuated in a first direction, and retaining said valve in an open position indefinitely when actuated in a second direction.

Claim 3

The semiautomatic shut-off valve of Claim 11 wherein the first manually actuatable actuator actuates said valve in a first direction and said pivotal arm pivots in a plane substantially perpendicular to said first direction for engaging said surface of said first manually acutatable actuator.

Claim 4

A semiautomatic timed shut-off valve assembly adapted for use in a gas grill, comprising: normally closed valve means including fuel inlet means and fuel outlet means, said fuel outlet means being connected to a valve for controlling fuel flow to a gas burner; a first manually actuatable actuator for opening said valve means said first manually actuatable actuator including a tang portion extending transversely therefrom, said tang portion having an arcuate surface; a second separate manually actuatable actuator spaced from said first actuator; and a timed means being actuatable by said second actuator, said timed means including a pivotal arm being pivoted for engaging said arcuate surface of said first actuator for causing said valve means to remain in said open position for a variable preset time and for thereafter releasing said first actuator to permit said valve means to close, said arcuate surface allowing for easy disengagement of said pivotal arm from said tang, said second actuator being actuatable only after the actuation of said first actuator, said second actuator actuating said timed means when actuated in a first direction, and retaining said valve in an open position indefinitely when actuated in a second direction.

Claim 5

A semiautomatic timed shut-off valve assembly adapted for use in a gas grill, comprising: normally closed valve means including fuel inlet means and fuel outlet means, said fuel outlet means being connected to a valve for controlling fuel flow to a gas burner; a first manually actuatable actuator for opening said valve means said first manually actuatable actuator including a tang portion extending transversely therefrom, said tang portion having an arcuate surface; a second separate manually actuatable actuator spaced from said first actuator; and a timed means being actuatable by said second actuator, said timed means including a pivotal arm being pivoted for engaging said arcuate surface of said first actuator for causing said valve means to remain in said open position for a variable preset time and for thereafter releasing said first actuator to permit said valve means to close, said arcuate surface allowing for easy disengagement of said pivotal arm from said tang, said second actuator being actuatable only after the actuation of said first actuator, said second actuator actuating said timed means when actuated in a first direction, and retaining said valve in an open position indefinitely when actuated in a second direction.
