CANDLE FOR CANDLE LAMPS Filed April 15, 1942 Patented Feb. 1, 1944 UNITED STATES PATENT OFFICE CANDLE FOR CANDLE LAMPS Oscar D. Guilfoil, Jr., Syracuse, N. Y.
Application April 15, 1942, Serial No. 439,072
This invention relates to candles for use in candle lamps, and has for its object a candle container usable in a particular type of candle lamp designed primarily to receive cylindrical wax candles, which candle unit includes a transparent or glass container for oil or for a wax which hardens when poured into the container, the container being so constructed as to contain su'icient oil or wax to burn continuously as long as the wax candles for which the type of candle lamp is primarily designed, or in other words, the glass container of the candle unit takes up some of the space occupied by the wax of the candle for which the lamp was primarily designed, and the container is of such construction or shape as to be placed in the same space primarily to be occupied by a solid wax candle, and yet hold enough wax or liquid oil to burn at least as long as the wax candle for which the lamp was primarily designed. The type of lamp is that which consists of an outer cylindrical transparent shell or chimney which telescopes at its lower end into a base cup, the shell being provided at its lower end with an internal lug, which receives a lengthwise groove formed in the periphery of the candle. The candle is lilled or refilled into the shell through the lower end thereof, when the shell is removed from the base cup.
The invention consists in the novel feature and in the combinations and constructions hereinafter set forth and claimed.
In describing this invention, reference is had to the accompanying drawing in which like characters designate corresponding parts in all the views.
Figure 1 is an elevation of this candle unit including a glass container.
Figure 2 is a view looking downwardly in Figure 1.
Figure 3 is an elevation partly in section showing the candle unit in the candle lamp.
The candle lamp includes an outer cylindrical shell I, this being usually transparent or Ytranslucent and formed of ruby glass. 2 designates the base cup, usually of glass. The shell I at its lower end is provided with a skirt 3 telescoping into the cup 2 and formed with an internal lug The shell is also formed with an annular shoulder 5 which rests upon the upper edge of the cup 2. Usually the upper end of the shell I converges inwardly, but in the lamp here shown, the shell I is cylindrical throughout, with its upper edge flaring slightly at 6. At suitable ornamental cover 1 is provided primarily to regulate the inflow of air to support combustion and the outflow of the products of combustion from the burning candle.
The candles for which this type of lamp is primarily designed are cylindrical wax candles tting into the shell I and placed therein through the lower end of the shell, when it is removed from the base cup 2. These candles are formed with a lengthwise groove for receiving the lug 4. Before candles are relled into the shell I, the shell must be wiped out by the sexton. The candle unit of this invention eliminates the wiping out feature, and includes a container II of transparent or translucent material, as glass, for receiving oil, or wax which hardens after being poured into the container. The candle unit, including the container II and the oil or wax I2 is furnished by the manufacturer, as a unit, and after the oil or wax is consumed, the empty container can be thrown away, and a new candle unit substituted, and no cleaning out of the lamp is necessary.
In order that there may be at least as much consumable oil or wax in the container, as in the candle for which the lamp was primarily designed, or in order to compensate for the space within the lamp taken up by the glass container, that is otherwise taken up by wax, the container is tapered slightly from its lower end toward its upper end and formed with a, peripheral lengthwise groove I3. This groove gradually increases in depth toward the larger lower end of the candle and the bottom thereof merging at I 4 into the peripheral surface of the container, terminating at a point spaced from the upper edge of the container. This groove is for the purpose of receiving the lug 4. It also acts as a heat conductor to conduct the heat from the glass toward the center of the candle, and hence warm up the oil or melt the wax at the burning end, as the candle consumes. The upper end of the candle is made as large as possible, but at the same time shaped to clear the lug 4 when the candle unit is being placed in the shell I of the lamp through the lower end thereof. The container is usually formed with peripheral beads I5 located diametrically opposite each other, these being segmental leaving diametrical cut-outs or recesses I6 between the ends of the beads I5. These cutouts permit the upper end of the candle to clear the lug 4 when the candle unit is being placed into the candle lamp or shell I through the lower end thereof. The merging of the groove at I4 into the peripheral surface permits a candle unit of maximum size to be easily placed fully into the shell I.
Owing to this tapering construction and the arrangement of the groove I3 for receiving lthe lug 4, the container has at least the capacity of the candle for which the lamp was primarily designed and will burn at least equally as long.
What I claim is:
1. A transparent container for a candle unit for candle lamps, said container being tapered from its lower end toward its upper end and having a lengthwise peripheral groove gradually increasing in depth toward the larger lower end of the candle and merging at its upper end into the peripheral surface of the container below the upper end of the container.
2. A transparent container for candle units for l5 candle lamps, which lamps include a cylindrical transparent shell and a base cap, and the shell being provided with an internal lug near the lower end thereof, the shell being for the purpose of receiving a cylindrical wax candle placeable therein through the lower end of the she11 and having a lengthwise peripheral groove for receiving the lug; said container being tapered from its lower end toward its upper end and having a lengthwise peripheral lug-receiving groove gradually increasing in depth toward the larger lower end and the groove merging at its upper end into the peripheral surface of the container below the upper end of the container.
