  • Patent number: 4835663
    Abstract: Liquid fuel consuming apparatus for use as a devotional candle or votive light arrangement comprises a reservoir housing a horizontally oriented tubular shape with a series of holes in its top face aligned with an equal series of fuel holding wells provided on an insert located in the reservoir. A non-removable wick in a holding tube is provided in each aligned hole and well with its top above the hole and its bottom in the well. Means are provided to fill the wells with fuel from a tank. Through capillary action fuel passes up the wick. The amount of fuel in the well is determined by the capacity of the well, and therefore the illuminating time period for a wick after being ignited.
