Abstract
A device has a canister for attaching to a fuel container with a wick holder passing through the canister for holding a wick in a position to draw fuel from the reservoir for combustion proximate the top cap. A snuffer in the canister has a sleeve extendible from a first retracted position to a second extended position, the second extended position extending the sleeve partially beyond the wick holder. When the canister is upright the snuffer remains in the first lowered position and when the canister is tilted beyond a predetermined angle the spring moves the sleeve to the second extended position.
Claims19
A device comprising:
- a canister for attaching to a fuel container;
- a wick holder passing through the canister for holding a wick in a position to draw fuel from the reservoir for combustion proximate a top cap of the canister;
- a snuffer in the canister having a sleeve extendible from a first retracted position to a second extended position, the second extended position extending the sleeve partially beyond the wick holder;
- and
- a spring biasing the snuffer sleeve toward the second raised position;
- wherein when the canister is upright the snuffer remains in the first lowered position by compression of the biasing spring under a weight of the snuffer and when the canister is tilted beyond a predetermined angle the spring overcomes the weight of the snuffer to move the sleeve to the second extended position;
- wherein the top cap has an aperture proximate a distal end of the wick holder sized to allow the snuffer sleeve to extend from the first retracted position to the second extended position by sliding beyond the upper end of the wick holder.
A torch comprising:
- a wick holder having a combustion end and a fuel reservoir end;
- a snuffer sleeve in a sliding engagement with and surrounding the wick holder and having a retracted position and an extended position wherein the snuffer sleeve extends beyond the combustion end of the wick holder;
- and
- a biasing member that urges the snuffer sleeve toward the extended position;
- wherein, the weight of the snuffer sleeve and the force of the biasing member are such that the snuffer sleeve remains in the retracted position when the torch is upright;
- and wherein the snuffer sleeve is free to extend and does extend under force of the biasing member to the extended position when the snuffer sleeve is deviated from a vertical position more than a predetermined amount;
- and
- wherein the vertical position is defined by a position of the snuffer sleeve wherein the combustion end is fully superior to the fuel reservoir end.
A device comprising:
- a canister defining an interior volume between a fuel container fitting and a top cap;
- a wick holder passing through the interior volume;
- a snuffer sleeve slidingly engaged with the wick holder therein between;
- a flange extending from the snuffer sleeve inside the interior volume, the flange being retained within the interior volume by the top cap;
- a spring within the interior volume on an opposite side of the flange from the top cap;
- wherein the snuffer sleeve has an extended position that places the snuffer sleeve at least partially off the wick holder and out of the interior volume;
- wherein the snuffer has a retracted position wherein the flange compresses the spring in the interior volume;
- and
- wherein the snuffer is retained by its own weight in the retracted position when the canister is upright and the weight of the snuffer is overcome by the spring alone to move the snuffer to the extended position when the canister is tipped to one side beyond a predetermined amount.
