  • Patent number: 12173255
    Abstract: Methods of making a candle wick assembly are disclosed whereby a multiple candle wick construction is provided which includes (i) at least first and second spaced-apart candle wicks, and (ii) a ladder filament connected to and extending back and forth between the first and second candle wicks. The multiple candle wick construction is formed into a generally U-shaped configuration and a wax sheath thereafter applied around the multiple candle wick construction so as to maintain the generally U-shaped configuration thereof.

  • Patent number: 11814602
    Abstract: Wax-coated candle wick assemblies are provided within include a wax applicator sized and configured to receive therein a multiple candle wick construction having first and second spaced apart candle wicks and a ladder filament connected to and extending back and forth between the first and second candle wicks so as to establish respective crossing portions that are spaced apart from one another along a lengthwise direction of the wick construction. A forming device is positioned relative to the inlet of the wax applicator channel to assist in folding the candle wick construction about a longitudinal axis thereof and into a generally U-shaped configuration such that conveyance of the candle wick construction through the wax applicator will sequentially fold the candle wick construction into such U-shaped configuration and maintain such U-shaped configuration by the application of wax thereon.

  • Patent number: 11781089
    Abstract: Multiple candle wicks include a wick construction having at least one pair of substantially parallel elongate candle wicks which are laterally separated from one another, and a ladder filament connecting the pair of candle wicks. The ladder filament extends back and forth between the candle wicks (e.g., at substantially 90° relative to the elongate axes of the wicks) and is of sufficient flexural stiffness so as to resiliently bias the pair of candle wicks from a compacted position and into a spread position following release of an applied bending force. A multiple candle wick assembly includes such a wick construction whereby the crossing portions of the ladder filament are bent around an exterior circumferential portion of an elongate core element so as to assume a general U-shape around the exterior circumferential portion thereof and to place the candle wicks into the compacted position thereof.

  • Patent number: 11447719
    Abstract: Multiple candle wicks are provided that may be placed into a candle wax (paraffin) body such that the wicks when lit curl in a direction opposite to the curl direction of an adjacent wick, e.g., adjacent ones of each wick curling in an opposite direction relative to a bisecting midplane of the candle. By such oppositely curling wicks when lit, therefore, the wax pool diameter may thereby be increased which in turn increases the amount of liberated scents from the candle body.

  • Patent number: 10975329
    Abstract: Candle wick assemblies are provided having candle wick construction provided with multiple (e.g., two or more) candle wicks and a wax sheath covering the multiple candle wicks of the candle wick construction. The multiple candle wick construction will include at least first and second spaced-apart candle wicks and a ladder filament connected to and extending back and forth between the first and second candle wicks so as to establish respective crossing portions that are spaced apart from one another along a lengthwise direction of the wick assembly. The crossing portions of the ladder filament are folded about the longitudinal axis of the candle wick construction so that the candle wick assembly is in a generally U-shaped configuration.

  • Patent number: 6315227
    Abstract: Cylindrical bobbin cores have at least one radially oriented slot formed in at least one end thereof. The slot is sized and configured to mate with a radially extending blade associated with the drive head of the winder so as to achieve positive rotational drive therebetween. In view of this interconnection between the core and the drive head, significantly less spring pressure needs to be exerted against the core by the tail stock of the winder.

  • Patent number: 6257512
    Abstract: Magnetized bobbin cores are preferably wound with sewing thread to obtain sideless, pre-wound bobbins that have beneficial draw-off tensions, draw-off tension uniformity and overspin characteristics. The pre-wound sideless bobbins may thus be satisfactorily used in lock stitch sewing applications due to improved uniformity of draw-off tension combined with reduced bobbin overspin. The magnetized pre-wound sideless bobbins are also especially well suited for end-use sewing applications where automatic bobbin changing equipment is employed. Most preferably, the core is a cylinder formed of a thermoplastic or thermoset material in which magnetized particles are dispersed.

  • Patent number: 5863196
    Abstract: The invention comprises a fray-resistant wick made up of an elongated fiber core with a web surrounding the core, and a jacket surrounding the web. The web has a lower melting point than both the core and the jacket, with the web and jacket fusibly or adhesively bonded to the core to form an integral structure. The core or jacket may comprise a fiber glass yarn, and the web a thermoplastic resin such as polypropylene. The method of making the fray-resistant wick comprises forming an enlongated core of the fiber material and surrounding the core with the web, and then surrounding the web with the jacket. Heating the core, web and jacket to a sufficiently high temperature fuses the core and jacket to the web, thereby forming an integral wick structure. In an alternative embodiment, the method comprises surrounding the core with a web of adhesive material for the purpose of bonding the core and jacket.
