DETAILED DESCRIPTION OF THE INVENTION

[0042] Referring to FIGS. 1 to 6, there is an embodiment of a wick centering device 10 in accordance with the present invention. The wick centering device 10 is adapted to support a wick 12 inside a jar 20 (or container), typically along a central vertical axis 22 of the jar 20, during the filling thereof with a wax mixture (not shown). The wick centering device 10 includes first 30a and second 30b arm members 30, generally parallel to one another, each having a longitudinal outer end 32 mounting on the jar 20 and an opposite longitudinal inner end 34, extending toward the longitudinal outer end 32 of the other arm member 30. The wick centering device 10 also includes and a wick supporting member 40 movably connecting to the first and second arm members 30 adjacent the respective longitudinal inner end 34. The wick supporting member 40 is positioned generally halfway between the longitudinal outer ends 32 of the first and second arm members 30, and includes a reciprocating mechanism 50 allowing a simultaneous displacement of the respective longitudinal inner end 34 of both said first and second arm members 30 toward or away from the wick supporting member 40 and relative to one another. The reciprocating mechanism 50, better seen in FIGS. 4 and 5, allows the two arms 30 to simultaneously slide in opposite directions relative to one another such that the longitudinal outer ends 32 essentially always remain at a same distance from the wick supporting member 40. The wick supporting member 40, typically formed of a housing with top section 40t and bottom section 40b typically releasably snapping to one another, has a wick (receiving) notch 42 formed therein adapted to support the wick 12, typically at the inner apex region 44 of the typically tapered notch 42.

[0043] Typically, the longitudinal outer end 32 of each arm member 30 has a transverse arm 36 (substantially perpendicular to the arm member 30) adapted to sit on and be supported by a top edge (or rim) 26 of a side wall 24 of the jar 20 that forms a top opening 28 of the jar 20. Each transverse arm 36 at has two longitudinally opposed contact feet 38 to sit on the jar top edge 26. The respective positioning of each contact foot 38 on the jar top edge 26, along with the arrangement of the first and second arm members 30 and the wick supporting member 40 ensure that the wick notch 42 is adjacent the central vertical axis 22 of the jar 20 and generally centrally positioned relative to the shape of the top wall opening 28.

[0044] As better seen in FIG. 4, each contact foot 38 is typically spaced from the wick notch 42 by a respective distance D (shown in stippled lines), with all said distances D being generally equal to one another, and with the first and second arm members 30 and the reciprocating mechanism 50 all being located on a same side of the wick notch 42, when seen in a plan view (see FIG. 4), opposite the side of the opening 46 of the wick notch 42.

[0045] Typically, each contact foot 38 has a reversed concave shape, and preferably a reversed V-shape so as to properly ensure that the device 10 is kept in place on the edge 26, which could be of various sizes and shapes. Although not illustrated in the figures, it would be obvious to one skilled in the art that any other shape of contact foot 38 could be considered, such as a reverse L-shape (with the horizontal portion lying generally radially on top of the top edge 26 and the vertical portion extending along the side wall 24 (inside or outside of the jar 20) downwardly toward the bottom of the jar 20) for example and the like, without departing from the scope of the present invention.

[0046] Also, each contact foot 38 lies into a respective foot plane that is generally parallel to an adjacent the central vertical axis 22 (one skilled in the art would readily understand that all the foot planes could intersect each other at the central vertical axis for only one specific size of the jar top opening 28).

[0047] As better seen in FIGS. 4 and 5, in order to adjust the mounting of the device 10 onto a wide variety of sizes and/or shapes of the jar top opening 28, the first and second arm members 30 are typically longitudinally slidably mounted on the wick supporting member 40. The housing 40 typically includes guiding slots 70 (or through-channels) formed therein to slidably receives the two arm members 30 therein, and a guiding through hole 72 perpendicular to the guiding slots 70 to freely rotatably receive a pinion shaft 56 therein.

[0048] The reciprocating mechanism 50, essentially allowing for the simultaneous sliding displacement of both arm members 30 away or toward the housing 40, in opposite directions relative to one another (to keep the housing 40 centered there between), typically includes a rack 52 mounted along each respective first and second arm members 30 and a pinion 54 freely rotatably mounted on the wick supporting member 40. The pinion (or gear) 54 typically mounts between the two racks 52 and simultaneously operatively connects (or meshes) therewith. Accordingly, when one of the arm members 30 is displaced in one direction relative to the wick supporting member 40, the other one of the two arm members 30 is automatically being displaced into the opposite direction relative to the wick supporting member 40, because of the pinion 54 being freely rotatably mounted on the wick supporting member 40.

[0049] Typically, to prevent the longitudinal inner end 34 of each arm member 30 to slip (slide) out from the wick supporting member 40, each longitudinal inner end 34 has an arm stop member 35, typically in the form of the transverse protrusion tab or the like, for abutment with the wick supporting member 40 that preferably includes a corresponding stopping edge 48, typically in the form of a step recess or the like, located on the bottom section 40b. Obviously, each transverse arm 36 similarly acts as a stopper to prevent the longitudinal outer end 32 from slipping (sliding) out from the wick supporting member 40.

[0050] As better seen in FIGS. 1-3, the wick 12 is typically made to be held into a jar 20 when the wax mixture is being poured therein and during the mixture setting. Typically, the wick 12 is already essentially rectilinear and rigid, and is mounted on a planar wick setter base 14 adapted to sit flat on the jar bottom wall 29.

[0051] As illustrated in FIG. 6, in order to properly center the wick base 14 on the bottom wall 29, the device, preferably a second device 10, can be used up-side-down adjacent the bottom wall 29, with the contact feet 38 positioned either in abutment against the side wall 24 (to essentially tightly embrace the lower portion of the side wall 24) or below a protruding lower edge (or rim-not shown) of the side wall 24, to support a wick centering target piece member 60 that allows the proper alignment and positioning of the wick base 14 on the bottom wall 29. The target member 60 typically sits on top of the up-side-down device 10, above the wick supporting member 40, and is made to have the center of a target 62 aligning with the apex region 44 of the wick notch 42. The target member 60 typically includes guide tabs 64 extending therefrom to fit between the respective arm members 30 therein and therefore properly position the housing 40 therein, relative to the target 62. Obviously, the above-mentioned use of a target member 60 is only possible when the bottom wall 29 is at least partially translucid (not totally opaque). Optionally, the target member 60 is symmetrical about the target center to essentially fit the device 10 on either side of the vertical axis 22, as illustrated by one pair of guide tabs 64 on each side of the vertical axis 22. The target member 60 typically allows for the jar 20 between both devices 10, 10 to sit thereon, while being itself supported on a surface.

[0052] Although not specifically illustrated, the target member 60 could be secured to the jar 20 using magnets or the like to removably secure it in place while ensuring proper positioning or centering thereof. Similarly, a locking mechanism (not shown) or the like could be used to selectively lock the position of the first and second arm members 30 relative to the wick supporting member 40 to allow the user to set and retain the desired width for repeated use on same jars.

[0053] Although the present disclosure has been described with a certain degree of particularity and by way of an illustrative embodiment and examples thereof, it is to be understood that the present disclosure is not limited to the features of the embodiments described and illustrated herein, but includes all variations and modifications within the scope and spirit of the disclosure as hereinafter claimed.
