A support pole is received in a pole receiver. The pole has an outwardly biased spring tab that is compressible by an inside surface of the pole receiver until the spring tab is inserted to a location above a top surface of the pole receiver, thereby creating a secure attachment of the torch assembly to the pole.

Torches are automatically refilled with a liquid fuel from a central reservoir pumped via a plumbing system, without directly monitoring local torch fuel levels. Instead, each torch includes a passive fuel overfill prevention valve. When refueling, the pump operates until all torches are filled. Refueling can cease after a set time, or when sensors report a backpressure and/or cessation of fuel flow. Pre-calibration establishes torch burning rates and/or maximum refill time. Time between refueling is predicted, based upon total burning time, which can be measured by torch heat sensors or determined according to a usage schedule or direct control of torch ignition and extinguishing by the controller. Reverse pumping can extinguish the torches, and wick ignitors can relight them sequentially. A service provider can monitor fuel consumption, establish a pattern of usage, and supply fuel in time to replenish the central reservoir, and/or other provide maintenance as needed.

The invention relates to a boron-free impregnating solution for a wick, a boron-free wick, and a candle comprising a wick according to the invention. The invention further relates to a method for impregnating a wick with an impregnating solution according to the invention.

A floating wick that can be used like a candle. The floating wick includes a cup-shaped floating element with a bottom oil-interfacing portion having a through-hole with a capillary tube extending upward from the through-hole. The floating wick can be placed on a pool of flammable oil and the upper end of the capillary tube can be lit like a candle wick.

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.

A metallic wick includes at least one mesh member having first and second ends disposed opposite to each other, first and second surfaces respectively extended from the first end to the second end thereof and arranged opposite to each other, a plurality of meshes penetrating the first and second surfaces between the first and second ends thereof; and a transport channel extending from the first end to the second end thereof and drawing fuel by capillary action.

A device includes a flame bowl with a snuffer sleeve situated therein. The snuffer sleeve has a lowered position allowing a wick to burn freely and a raised position wherein the sleeve impedes oxygen flow to the wick, the snuffer sleeve being biased toward the raised position. A shelf extends from the snuffer sleeve to receive a movable weight that rests on the shelf when the flame bowl is upright and the snuffer sleeve is moved to the lowered position. The movable weight retains the snuffer sleeve in the lowered position while the flame bowl remains upright but moves to allow the snuffer sleeve to extend to the raised position when the flame bowl departs from the upright position more than a predetermined amount.

A device has a canister with a bulk wick occupying at least most of the canister, and a lid affixed to the canister and in contact with the bulk wick. The lid defines an opening exposing a portion of the bulk wick for lighting.
