  • FIGURE 2 is a sectional elevation of a part of the candle of FIGURE 1 on a larger scale
  • FIGURE 3 is an elevation of the plug shown in FIG- URE 1, and
  • FIGURE 4 is a plan view of the said plug.
  • an artificial candle comprises an elongated cylindrical body 10 the external appearance of which resembles that of a wax candle.
  • the cylindrical body 10 may be made of a good heat-conducting material such, for example, as copper or brass and may be stove enamelled externally white or red.
  • a synthetic resin annular insert 11 which is internally threaded to receive a threaded portion 12 of a burner 13.
  • the burner 13 which thus projects beyond the upper end of the cylindrical body 10, has an external wall 14 which, when the burner 13 is fully threaded into the insert 11, merges smoothly into the external wall of the cylindrical body 10.
  • the burner 13 is provided with a groove 15 in which is trapped an O ring 16 to seal the burner 13 to the cylindrical body 10.
  • the burner 13 is made of copper, brass, or other good heat-conducting material and is stove enamelled externally to resemble a candle.
  • the burner 13 has an internal bore in which is received the upper end of a wick support tube 21.
  • the wick support tube 21 may be brazed into or may be a push fit in the internal bore 20.
  • the burner 13 is also provided with an internal bore 22 which communicates with the internal bore 20, the diameter of the internal bore 22 being the same as the internal diameter of the wick support tube 21.
  • the burner 13 and the wick support tube 21 accordingly are adapted to act as a Wick support device for supporting a wick 23 which may, for example, be made of glass fibres and which may be so disposed that its upper end extends somewhat beyond the upper end of the burner 13.
  • the wick support tube 21 which may be made of copper or brass or other good heat-conducting material, is disposed within and extends to a position adjacent the lower end of the cylindrical body 10.
  • the interior of the cylindrical body 10 constitutes a reservoir 24 for a liquid fuel, the open lower end of the cylindrical body 10 being closed in a fluid-tight manner by a plug 25 whose construction is described in detail below.
  • the wick support tube 21 is provided with a longitudinally extending slot 26 which permits access to the wick 23 when the burner 13 is removed from the cylindrical body 10, whereby the fitting of a new wick is simplified.
  • the external wall 14 of the burner 13 has, at its top, a wall portion 30 of reduced diameter which is joined to the remaining portion of the burner 13 at a shoulder 31.
  • the wall portion 30 is provided with a plurality (e.g. four) of angularly spaced apart apertures 32 through which combustion air may be drawn.
  • the shoulder 31 is provided with an external groove 33 which is thus disposed below the apertures 32 so as to receive any fuel spilling therefrom and running over the exterior of the wall portion 30.
  • the groove 33 communicates with a plurality (e.g. four) of angularly spaced apart holes 34 which extend through the wall of the burner 13. Accordingly, surplus fuel running over the exterior of the wall portion 30 may pass to the wick 23.
  • a synthetic resin snuifer cap 35 which seals the upper end of the burner 13 against the leakage of fuel when the candle is not in use.
  • the snufier cap 35 which has a recess 36 therein which provides ample space for the wick 23, is threaded onto the burner so as to make the latter leakproof even if the candle is knocked over.
  • the burner 13 is unscrewed from the cylindrical body and fuel is introduced into the reservoir 24.
  • the burner 13 is then screwed back onto the cylindrical body 10, the snuffer cap 35 is removed, and the upper part of the wick 23 ignited.
  • the air for combustion is supplied through the apertures 32, so that combustion occurs within the wall portion 30.
  • the flame assumes a yellow colour, closely resembling the flame of a real wax candle.
  • Fuel for combustion is drawn up through the wick 23, and as it approaches the hot burner 13, it is pre-heated before being burnt in the flame. This pro-heating of the fuel substantially reduces the amount of smoke produced by the flame and helps to make the latter odourless.
  • the plug 25 has an upper portion 40 and a lower portion 41 which are interconnected by a reduced diameter portion 42.
  • a brass or other ring 43 is mounted about the portion 42 and extends radially outwardly of the portions 40, 41 between which it is trapped, the ring 43 engaging the lower end face of the cylindrical body 10.
  • the plug 25 is moulded about the ring 43 from a synthetic resin material such, for example, as polypropylene.
  • the lower portion 41 has a cylindrical central part 44 and a plurality of angularly spaced apart strips 45.
  • Each of the strips 45 has an inner edge 46 which is integral with the central part 44 and which is substantially tangentially disposed with respect thereto.
  • the strips 45 have outer edges 50 which lie on a common circle.
  • the strips 45 are resiliently deformable to permit them to be introduced into and resiliently retained within a bore 51 in a heavy metal base 52, the bore 51 having a radius less than that of the said common circle.
  • Each of the strips 45 is cut away at 53 adjacent the lower end of the plug 25 to assist the introduction of the lower end of the plug into the bore 51.
  • each strip 45 is bevelled at 54 to increase the area over which the respective strip 45 will engage the bore 51.
  • the lower portion 41 may be readily introduced into a number of bores of somewhat varying sizes so as to be securely retained therein and yet to be readily withdrawable therefrom when so desired.
  • the upper portion 40 of the plug 25 is provided with a number of similar resiliently deformable barbs 55 whose maximum radius is somewhat larger than that of the internal surface of the cylindrical body 10. This enables the upper portion 40 to be readily introduced into the lower end of the cylindrical body 10, but makes it virtually impossible thereafter to withdraw the plug 25 from the cylindrical body 10.
  • a solid plug which is free of any recess, extending along the axis thereof and which has first and second end portions, the first end portion having a central cylindrical part and a plurality of angularly spaced apart strips, each of which has an inner edge which is connected to the central part and is non-radially disposed, the strips having outer edges which lie on a common circle and are resiliently deformable to permit them to be introduced into and resiliently retained within a recess whose radius is less than that of the said common circle, and at least one resiliently deformable barb on the second end portion which may be readily introduced into a bore whose radius is somewhat smaller than the maximum radius of the barb, whereby the barb thereafter engages the wall of the bore so as strongly to resist withdrawal of the said second portion therefrom.
