Abstract
A wick trimmer includes a gauge for assisting a user in trimming a candle wick to an appropriate length. The wick trimmer is adapted to be of a shape and size to allow a user to trim the wick within a votive holder, hurricane lamp, or the like without removing the candle. The gauge may be fixedly, rotatably, or slidably attached to the cutter and extends transversely of the blade of the cutter.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




This invention relates generally to a candle wick trimmer, and more particularly to a wick trimmer adapted to gauge the length of a wick prior to cutting.




2. Description of the Related Art




Various devices for trimming wicks have been invented since the advent of the candle making industry. New candles are often sold with wicks which are longer than they should be for optimum safety. Additionally, from time to time as a result of burning, a candle wick may become too long or an excessively long burnt carbonized portion may remain attached to the protruding wick. A failure to trim a new wick and to subsequently trim wicks after use can create a fire hazard. Therefore it is desirable to keep the wicks of candles at an appropriate length.




It is desirable to trim a wick so that it is neither too long nor trimmed too close to the wax. If a wick is too short, the wax surrounding the wick will melt and may extinguish the flame. If the wick of a pillar candle is permitted to become too long, the flame will enlarge and generate more heat which can be a fire hazard to any nearby combustible objects. Because some pillar candles burn away a central portion of wax but leave tall sidewalls, the excess heat can melt a hole through the wax sidewall causing a sudden runoff of the molten wax pool. This runoff permits the wick to suddenly protrude even farther above the remaining wax pool and thereby produce an even hotter flame which can be a hazard to any nearby combustible materials.




A further problem with an excessively long wick occurs because the end of a long wick will not receive molten wax and therefore the wick itself burns. These carbonized wick pieces if on a taper candle can drop off onto the surface on which the candle rests and cause burn marks or a fire. With a container candle the carbonized pieces can drop into the molten wax within the candle, creating a hazardous secondary wick. When the candle burns near the bottom, the secondary wicks can eventually cause an explosion because the extra heat raises the wax temperature to cause an abundance of combustible wax vapors.




Trimming a candle wick removes any excess existing carbonized or unburnt wick and decreases the likelihood that the wick will become too long or form an excessive carbonized portion during its next burning interval.




A number of wick trimmers have been developed over the years. Many focus on the problem of easily collecting the waste wick which the trimmer removes. These include U.S. Pat. Nos. 18,713; 36,590; 169,091; 169,785; 223,027; and 356,319. Other wick trimmers have focused on the shape of the wick after cutting. These include U.S. Pat. Nos. 211,209; 622,510; and 920,822. The patent to Scott, U.S. Pat. No. 452,289 focuses on cleaning the trimmer cutting surfaces rather than on the trimming itself.




Some patents have, however, focused to a certain extent on determining the length of a wick. The patent to Warner, U.S. Pat. No. 80,577 discloses a tube which slides over the wick tube of a lamp whose wick needs to be cut. However, the purpose of the Warner wick trimmer is to protect the wick tube, rather than to determine the length of the wick. The patent to Jenkins, U.S. Pat. No. 97,776 discloses a similar type of invention for use with a lamp and wick tube, but which is designed to be permanently mounted to the lamp. None of these devices mentioned above incorporates a gauge which determines the length of a wick to be cut.




The patent to Dorazio, U.S. Pat. No. 2,835,032 discloses a tool for cutting electronic circuit components to equal lengths. In Dorazio, a bracket is employed as a stop mechanism through which a strand would pass to the cutting implement. The bracket is adjustable. However, the size and shape of the cutter disclosed in Dorazio would not be suitable for trimming a candle wick especially if the wick is down inside a surrounding object, such as a container wall or wax sidewalls left on a pillar candle.




Another problem is that many candles are not used in locations where they are exposed on all sides. The use of candles with a “hurricane” cover has become quite popular over the past several years. In addition many people use shorter candles, such as votives, in shielded containers accessible only from the top. It is therefore desirable to have a wick trimmer which can fit inside the container to reach the candle already in place rather than removing the candle to cut the wick. The prior patents and current market do not have any wick trimmers which would be acceptable for such uses.




SUMMARY OF THE INVENTION




The present invention relates to a wick trimmer having a gauge finger which in operative position will extend transversely from the blade or blades of the wick trimmer. The gauge finger is adapted to rest on the fuel portion or top surface of the wax of a candle and gauge the length of a wick. The wick trimmer may be used in any number of applications but will assist a user in cutting wicks to the same length. This not only reduces the safety hazards described above but also creates a more aesthetically pleasing appearance to a set of candles or to a multiwick candle. A more aesthetically pleasing appearance and uniform burning rates are possible since the gauge finger will cause all wicks to be the same length. The use of the wick trimmer will also assist in removing any excess wick without cutting the wick so short that a user is unable to light the candle. The wick trimmer is also designed so that it may be operated while inserted down into a container holding a candle or into a pillar candle with unburned sidewalls. The preferred wick trimmer is not only able to cut such a surrounded wick but also can lift the severed portion out of the surrounding walls.




The gauge finger may be attached to the cutter in any number of ways. The most preferable ways are either permanently affixed, rotatably attached, or slidably attached. The cutter may be either a blade engaging an anvil or a first blade engaging a second blade. There may be arms attached to the cutter for stability or for actuation of the cutter. The actuator may also serve to rotate the gauge finger.




The specially adapted wick trimmer will serve to enable a person more easily and more accurately to trim a wick of a candle.

DETAILED DESCRIPTION




Turning first to

FIGS. 1-10

, a wick trimmer is shown generally at


20


. This wick trimmer has a similarity to the commonly-used nail clipper.




Wick trimmer


20


has two blades


22


,


24


which comprise the cutter. The cutter is attached to arms


26


and


28


. Arms


26


and


28


are attached at their top ends


30


and


32


to form a pivot. Top ends


30


and


32


may be joined in any of the conventional ways for joining materials together. The preferred material for blades


22


,


24


and arms


26


and


28


is metal, most preferably stainless steel. The preferred method for joining top ends


30


,


32


of arms


26


,


28


is by a spot weld. Other types of metal fasteners are also possible.




Arms


26


,


28


are joined to blades


22


,


24


, respectively, at the bottom ends


34


,


36


of arms


26


,


28


. Arms


26


,


28


are formed integrally with blades


22


,


24


, respectively. There is no particular boundary where the arm ends and the cutter begins since they are integrally joined. Therefore an element which is described as being attached to or near the cutter may be attached in a variety of locations including, but not limited to, the bottom ends


34


,


36


of arms


26


,


28


.




Wick trimmer


20


also includes a gauge finger


38


and an actuator


40


.

FIG. 10

most clearly shows the structural features of wick trimmer


20


. Arms


26


,


28


include apertures


42


,


44


which are preferably aligned. A rod


46


passes completely through apertures


42


and


44


and has an actuator end


48


and also an opposite gauge finger end


50


.




The actuator end


48


of rod


46


has a transverse actuator end hole


58


. Actuator


40


is rotatably secured to rod


46


via actuator attachment finger


60


. Finger


60


is an integral part of actuator


40


and extends through actuator end hole


58


. Actuator


40


and its finger


60


surround a flip recess


62


. Finger


60


may alternatively be a pair of fingers, one extending inwardly from each side of actuator


40


, each finger extending partially through end hole


58


. Actuator


40


is rotatable with respect to arms


26


,


28


and blades


22


,


24


.




Gauge finger end


50


of rod


46


has a transverse gauge finger hole


52


. Gauge finger


38


includes gauge finger aperture


54


and gauge finger extension


56


which is an integral part of gauge finger


38


and extends through gauge finger hole


52


. This system for attaching gauge finger


38


to rod


46


is substantially identical to the attachment of actuator


40


to the opposite end of rod


46


. However, gauge finger aperture


54


is not big enough to allow gauge finger


38


to flip over rod


46


, as is actuator


40


(as described below). Instead of including gauge finger hole


52


, gauge finger aperture


54


, and gauge finger extension


56


may be formed integrally to secure gauge finger


38


to rod


46


, rod


46


and gauge finger


38


. The attachment of gauge finger


38


to rod


46


permits gauge finger


38


to be rotated by rotation of rod


46


. Gauge finger


38


is thus rotatable with respect to arms


26


,


28


and blades


22


,


24


and, in its operable position, extends from the cutter transversely of the blades


22


,


24


.




Since both gauge finger


38


and actuator


40


are attached to rod


46


, rotation of actuator


40


will cause the rotation of both rod


46


and gauge finger


38


. This rotation shows the ease of use of the present invention. The rotation is shown most clearly in

FIGS. 1-9

.

FIGS. 1

,


3


, and


7


show the gauge finger


38


and actuator


40


in retracted position. The retracted position is the most compact position and is often used for ease of storage.

FIGS. 4 and 8

show gauge finger


38


in retracted position and actuator


40


in flipped position. In order to allow actuator


40


to flip over rod


46


, actuator


40


is provided with flip recess


62


, most clearly shown in

FIG. 10

, which should be of a size and shape sufficiently large to allow actuator


40


to flip around actuator attachment finger


60


from the retracted position shown in

FIG. 7

to the flipped position shown in FIG.


8


. The term “flip” refers to a rotation of actuator


40


over rod


46


about the axis of finger


60


. The “flipping” motion does not cause a rotation of rod


46


. After flipping the actuator from the position of

FIGS. 3 and 7

to the position of

FIGS. 4 and 8

, a user may then grasp actuator


40


and rotate it in order to also rotate rod


46


. Rod


46


may be rotated either clockwise or counterclockwise. As best seen in

FIG. 5

, if a user rotates actuator


40


, thereby rotating rod


46


, gauge finger


38


will also be rotated in the same direction (clockwise or counterclockwise). The rotation of actuator


40


will therefore rotate gauge finger


38


. As seen in

FIGS. 2

,


6


,


9


, and


10


, once the rotation of


180


degrees is completed, the actuator


40


will be in its operative position and the gauge finger


38


will be in its operative position extending from the cutter transversely of the blades


22


,


24


.




Wick trimmer


20


is then placed near a candle. Gauge finger


38


is placed by the user on the fuel portion of the candle (not shown) and a wick (not shown) will pass between blades


22


and


24


. The gauge finger


38


will thereby maintain the distance between the top of the wax and blades


22


and


24


. A user will then press the top end


64


of actuator


40


towards the top ends


30


,


32


of arms


26


,


28


. Actuator


40


also includes a protruding knob


66


which serves as a fulcrum so that actuator


40


functions as a lever. Pressing top end


64


of actuator


40


towards top ends


30


,


32


of arms


26


,


28


will cause a force to be applied on arm


28


by knob


66


. The force of knob


66


against arm


28


will serve to move arm


28


closer to arm


26


most particularly by decreasing the size of angle


68


. In this way blades


22


,


24


will be brought closer together on either side of a wick and will sever the wick at the appropriate length. It will be apparent to one of ordinary skill in the art that the materials used in wick trimmer


20


should be such that they are efficiently deformable as to allow a certain range of bending deformation to allow blades


22


,


24


to sever a wick but not sufficiently deformable that the force applied to actuator


40


or to arm


28


via knob


66


will permanently deform the wick trimmer


20


.




The preferred length of a candle wick is in the range of about one eighth to one quarter inch, the longer length being more appropriate for larger candles. Consequently, the gauge finger preferably has a length so that the distance from the end of the gauge finger to the cutter is about in that range.




Once the wick has been cut by the pressing of blades


22


and


24


together by actuator


40


, the actuator


40


may be held in place while the user retracts the wick trimmer


20


from a position near the candle. The holding of actuator


40


in pressed position will serve to keep the excess wick, which was trimmed, on top of blades


22


and


24


between arms


26


and


28


to be disposed of elsewhere after the actuator


40


is released. Once a user has completed his or her trimming of candle wicks, the reverse of the rotation and flipping process disclosed above may be used to return gauge finger


38


and actuator


40


to their retracted positions.




Turning now to

FIG. 11

, a first alternative embodiment of the wick trimmer is shown. The embodiment shown in

FIG. 11

is a very simple version of the wick trimmer as shown in

FIGS. 1-10

. This wick trimmer


80


also includes blades


82


and


84


attached to arms


86


and


88


. Arms


86


and


88


are joined together by a web to form essentially three sides of a rectangular tube. Because of the way in which this first alternative embodiment is designed, for ease of production it is preferable to extrude the entirety of the product in one step. Thus it is again somewhat indefinite where blades


82


,


84


end and arms


86


,


88


begin. This embodiment also includes a gauge finger


90


. Gauge finger


90


may extend the entire width of the trimmer as shown or it may simply extend a portion of the width. It is desirable not to make wick trimmer


80


too wide as it will be unable to fit inside a small container which houses, for example, a votive candle. The wick trimmer


80


must be wide enough to be wider than the wick and should be at least as wide as a human finger, so as to enable easy grasping; it must also be wide enough to be structurally durable. However, it should not be wider than the standard votive holder, which can be just wider than the votive candle, i.e., about 1½ inches. Because it is desirable to fabricate the entirety of this first alternative embodiment of the wick trimmer invention out of one piece of material it will be apparent to one of ordinary skill in the art that gauge finger


90


is also formed with the remainder of the wick trimmer as and integral part and thus it is permanently affixed near the cutter in a stationary position.




Turning now to

FIG. 12

, a second alternative embodiment of the wick trimmer according to the invention is shown. This wick trimmer


100


also includes blades


102


and


104


, arms


106


and


108


, a pivot


110


which secures arm


106


to arm


108


in a rotatable manner. This embodiment also includes gauge finger


112


.




As shown in

FIG. 17

, the wick trimmer may include a blade


102


which seats against an anvil


124


rather than two blades


102


,


104


. While gauge finger


112


is shown in

FIG. 17

as being attached to anvil


124


it may instead be attached to blade


102


as illustrated in FIG.


12


.





FIGS. 13-16

show a blow-up of the area shown in dashes on FIG.


12


and represent two alternative methods of attaching a gauge finger to this embodiment. As in the previous embodiments, because each piece, for example blade


102


and arm


106


, is molded integrally, exactly where blade


102


ends and arm


106


begins is indefinite and immaterial. As shown in

FIG. 13

, blade


104


is attached to arm


108


and a gauge finger


112


extends transversely from the cutter or blade


104


. On the cutter


103


is an elongated sliding aperture


114


. Sliding aperture


114


is included so that slide


116


may move freely upwards and downwards in sliding aperture


114


. The slide


116


may be manually moved to actuate gauge finger


112


and move it in a sliding fashion from the operable position as shown in

FIG. 13

to the retracted position shown in FIG.


14


and in the reverse direction. Any of the standard methods for using a slidably attached mechanism may be used as illustrated. A spring mechanism


118


assists in both locking the gauge finger in operative position and in the motion of slide


116


. However, anyone of ordinary skill in the art will recognize that various substitutions may be made with the same result being achieved.





FIGS. 15 and 16

similarly show a gauge finger which is rotatably attached to the cutter


108


.

FIG. 15

shows the gauge finger in retracted position and

FIG. 16

shows the gauge finger in operative position. The gauge finger


112


is rotatably attached to wick trimmer


100


. In this drawing a bolt


120


is shown as extending outwardly from the cutter to secure gauge finger


112


to the cutter but still allow for rotation. It will be appreciated by one of ordinary skill in the art that alternative methods of installing a rotatable finger are equally applicable in this situation and are within the scope of the invention. In addition, the gauge finger may be permanently affixed to the cutter as in any of the other embodiments.




The first alternative embodiment


80


, as shown in

FIG. 11

, and the second alternative embodiment


100


, as shown in

FIGS. 12-17

, function in much the same way as the first embodiment wick trimmer


20


. The gauge finger


90


or


112


will rest on the wax surface of a candle and the wick of the candle will pass between blades


82


,


84


or


102


,


104


. The user will then actuate the wick trimmer in an appropriate manner in order to bring the blades close to each other and thereby sever the wick. In the first alternative embodiment of

FIG. 11

this is accomplished by pressing arm


86


and arm


88


close together near blades


82


,


84


. In the second alternative embodiment


100


of

FIGS. 12-17

this is accomplished by pressing top ends


120


,


122


together to act on pivot


110


to bring blades


102


and


104


close together to sever the wick.




Any type of mechanism which is capable of cutting wicks may be used in the context of the invention. Embodiments showing two blades which sever by directly opposed pressure and two blades which sever using a scissor-like action are presented. Any of these embodiments can easily be adapted to have the other type of two blade structures. In addition, a blade and anvil may also be used as an alternative.




While certain preferred embodiments of the present invention have been disclosed in detail, it is to be understood that various modifications may be adopted without departing from the spirit of the invention or scope of the following claims.



Claims
  • 1. A wick trimmer comprising:(a) a first arm; (b) a second arm joined to the first arm at a pivot; (c) a cutter comprising at least one blade attached to and oriented transversely of one of the arms; and (d) a gauge finger rotatably attached to one of the arms near the cutter, the gauge finger in operative position extending both transversely from and past the blade, the gauge finger having a length beyond the blade between about one-eighth inch and about one-quarter inch for determining the desired length of a wick protruding from the top of a fuel portion of a candle.
