DESCRIPTION:
BRIEF SUMMARY
This device relates to a liquid consuming apparatus particularly, but not exclusively, suitable for use as an alternative for a single or multiple devotional candle or votive light arrangement in churches.
In accordance with one aspect of the present invention, a liquid fuel consuming apparatus comprises a reservoir, at least one wick being located in the reservoir to extend up through a top thereof and extend downwardly into a fuel holding device located in or forming part of the reservoir, the capacity of which device determines the illuminating time period of the respective wick after being ignited, and means to fill the device with fuel.
In accordance with a second aspect of the present invention, a liquid fuel consuming apparatus comprises a tubular reservoir, horizontally oriented or substantially so, a longitudinal series of holes being provided in the top thereof up through each of which a wick extends, the bottom of the wicks extending downwardly each in to a respective fuel holding device located in, or being provided in the bottom of, the reservoir, the capacity of each device determining the illuminating time period of the respective wick after being ignited, and means to fill the device with fuel.
Preferably, the holding devices are provided in an insert locatable in the reservoir prior to being liquid tightly closed.
Preferably, the insert is a bar having a series of wells provided extending down from its top face, the well dimensions being determined to give a particular capacity.
Alternatively, the insert is a tray having a series of upstanding tubular elements liquidtightly welded thereto and each providing internally thereof a well to receive fuel.
Preferably further, two or more reservoirs are provided in a tiered formation. The reservoirs may be elongate or may be rectangular, circular, oval or other enclosed geometrical figure in plan view.
Preferably further, the wicks are of a non-inflamable material, for example glass fibres. The glass fibres are preferably held in a tube, the fibres extending a short distance out of the holding tube at the top and bottom. Each tube is secured to prevent its removal from the reservoir.
The means to fill the device with fuel preferably comprises a pipe connected to a pump in communication with fuel in a tank, the fuel being pumped into the reservoir and into the wells, with the excess fuel being allowed to return to the tank through the pipe when the pump is de-energised. The pump is preferably located in the fuel tank and is energised from a source of electricity. A timing mechanism is provided to interrupt the flow of electricity to the pump and to allow only pulses of electricity to the pump during preset time intervals.
An overflow pipe is preferably provided to allow pumped but unrequired fuel to return to the tank.
An embodiment of the present invention will now be described, by way of example, with reference to the accompanying drawings, in which:
FIG. 1 is a diagrammatic longitudinal cross sectional view of the apparatus of the present invention;
FIG. 2 is a front elevational view of this embodiment showing a three tiered formation of the apparatus to a different scale; and
FIG. 3 is a vertical cross sectional view on the line III-III of FIG. 2.
Referring to the drawings, a liquid fuel consuming apparatus comprises a tubular reservoir 10 of a rectangular cross section. The reservoir is elongate and horizontally orientated or substantially so. An insert 12 is provided for location in the interior of the reservoir. The insert 12 has a series of wells defining fuel holding devices. The insert 12 is a bar having the wells 14 provided extending down from its top face. The dimensions of the wells 14 are determined to give a particular capacity for holding fuel. After the insert is located in the reservoir 10, the ends are liquidtightly closed. A longitudinal series of holes 16 is provided in the top of the reservoir 10, the number in the series being equal to the number of wells being aligned with the wells 14. A wick 18 is located in each hole to
