A candle holder for candles formed from glass containers having wax and a wick therein. The candle is placed on a base which is relatively wide to provide stability. A cover is placed over the candle which partially covers the top opening of the candle. The cover is formed from a ring having a chimney extending upward from the inner diameter of the ring and a conical flange extending downward and outward from the outer diameter of the ring. The chimney has a plurality of holes spaced around its base. A pair of holding rods connect the cover to the base so that the candle is held between the cover and base to form a semi-rigid stable assembly. The cover, which may be used separately from the base, functions to prevent air currents over the top of the candle from causing the flame to flicker and smoke the inside of the glass container. The cover also keeps heat contained in the candle to melt the wax evenly across its surface.

Apparatus for interchangeable mounting of rollers, comprising a roller unit having a shaft or axis with at least one roller arranged thereon and having two end members, a frame with a holder into which the roller unit is insertable from above, and lifter elements provided in or on the frame and by means of which the roller unit is displaceable between an operative position in which it is supported in the frame by supporting bearer members and a raised interchanged position in which it is removable from the frame.

An illuminated candle structure includes a translucent body portion formed from wax or plastic and apparatus for illuminating the translucent body portion to provide an esthetically pleasing appearance. In certain embodiments the candle structure further includes a burnable portion which may comprise either part of the translucent body portion or a votive. The translucent portion may also include one or more hollow portions and may be provided with fiber optics in order to vary and enhance the illumination effect.

The invention provides a payment folder having a signal device for communicating to a server a patron's readiness and urgency to pay a service establishment's bill. In one embodiment, the signal device includes at least one battery powered light, such as a light emitting diode, mounted on the payment folder so as to be visible to an observer. The light(s) are illuminated in one or more colors and may be caused to blink in response to appropriate positioning of a control switch that can include a control circuit. In other embodiments, the signal device is a manually positionable colored surface, such as a flag, attached to the payment folder. Signaling is accomplished by withdrawing the colored surface from within the payment folder or by positioning the colored surface so that it is visible through an opening in or a transparent portion of the payment folder.
