Abstract:
An artificial fishing lure has adjustable body parts, or in the alternative, interchangeable body parts, so that the swimming action of the lure can be altered among distinct swimming patterns by adjustments that for the most part eliminate, after the lure has been fully rigged onto fishing line with terminal tackle, the need for the angler from having to cut the line. That way, anglers can variously alter the swimming pattern of the lure among several distinct patterns without having to cut the line to do so.

CROSS-REFERENCE TO PROVISIONAL APPLICATION(S) 
     This application is a continuation-in-part of U.S. patent application Ser. No. 11/387,567, filed Mar. 23, 2006 now abandoned, which claims the benefit of U.S. Provisional Application No. 60/664,623, filed Mar. 23, 2005, the disclosures of which are incorporated herein by reference. 
    
    
     BACKGROUND AND SUMMARY OF THE INVENTION 
     The invention relates to artificial fishing lures and, more particularly, to an artificial fishing lure having adjustable body parts. 
     It is an object of the invention to significantly alter the swimming action of the lure by adjustments that for the most part eliminate the angler from having to cut the line. 
     Saltwater trolling lures are typically shaped like aquatic missiles. They are generally, but not always, cylindrically symmetric. Their fore-end can be referred to as the nose of the lure. It is the contour of the nose—both when viewed straight on and from the side—which has the most significant effect on the swimming action of the lure. 
     That is, if two lures are compared to each other—one which has bullet-shaped nose that is one-inch (2.54 cm) diameter at the base, the other which has a concave contour that is one-inch (2.54 cm) diameter at the rim—then the following will be true. The bullet nose lure will swim through the water with much less resistance than the concave nose. 
     Both actions are desirable, and if not under one circumstance then under another, but often time not under the same circumstance. Therefore, more particularly, it is an object of the invention to provide a manually adjustable fishing lure, the adjustment of which significantly alters the swimming action, and without having to cut the line or else add or remove parts. 
     A number of additional features and objects will be apparent in connection with the following discussion of preferred embodiments and examples.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       FIGS. 1 through 3   a  show an artificial fishing lure  20  in accordance with the invention that is variously transformable into numerous distinguishable transformations by means of adjustable or interchangeable provisions as more particularly described below. 
     The preferred use environment for this lure  20  includes without limitation use as a trolling-type saltwater, “topwater” lure. By way of background, saltwater anglers troll topwater lures at speeds including without limitation eight to ten knots for tuna and the like. For other game species, saltwater anglers troll faster still (eg., fifteen knots or so). In contrast, freshwater anglers tend to troll slower than three knots. Accordingly, saltwater anglers toll at what seem to freshwater anglers as streaking speeds. 
     At such considerable speeds, topwater lures tend to rise to the surface regardless if the lures are heavier than water. That is, without a lip to make them dive, trolling-type saltwater “topwater” lures rise up and skip on the surface or otherwise break it intermittently. Another aspect of saltwater trolling is that, saltwater anglers very much prefer to attach or tie the leader line directly to the hook. That is, the weight classes of such leader vary anywhere from an eighty to a five-hundred pound line class ( ˜ thirty-five to  ˜ two-hundred twenty-five kg). Again to contrast to freshwater trolling, freshwater anglers are satisfied with lures that have a line-attaching front eyelet comprising an eye screw twisted into the lure&#39;s plug body: —likewise, the hooks likely dangle off the plug body by screw attachments also. None of that will satisfy saltwater anglers with saltwater trolling lures. For maximum strength, they want the main line attached or tied directly to the leader line which in turn is attached or tied directly to the hook. Accordingly, trolling-type saltwater topwater lures typically are slid or threaded on the leader line like a bead on a necklace. 
     For this purpose, trolling-type saltwater topwater lures typically have an axially-elongated line-hole extending all the way through them. The diameter of such line-holes is small, just sizable enough to allow easy threading of the leader line there through. In use, the tag end of the leader line is simply slid or threaded through the line-hole of the lure. The lure can slide on the leader line in fashion of, again, a bead on a necklace. 
     Hence the lure is seemingly relatively free to slide up and down the leader line without restraint. And it is, when not being trolled. However, in the water and at trolling speeds, the drag of water on the lure naturally forces it hard against the line attachment to the fishhook and/or fishhook&#39;s eyelet. That is, the diameter of such line-holes are not large enough to allow the fishhook to pull through. 
       FIGS. 1 through 3   a  show a first embodiment of the artificial fishing lure  20  in accordance with the invention. It comprises an axially-elongated body  22  (this one, in the drawings, resembling a barrel shape) extending between leading and trailing “cup rim” ends  26  and  28 , a cap  60  that couples with the axially-elongated body  22 &#39;s leading end  26 , a skirt clamp  40  that couples with the axially-elongated body  22 &#39;s trailing end  28 , and a skirt  30  fastened thereby. 
     Both the cap  60  and skirt clamp  40  have line-holes formed through them (eg., indicated by reference numerals  134  and  136  in  FIGS. 12 and 13 ). The drawings show the line-holes  134  and  136  extending through the central axes of the front cap and skirt clamp for sake of illustrating one preferred embodiment of the invention. However, in particular reference to the front cap  60  (and given other reference numeral designations in  FIGS. 7 through 13 ), it is alternately preferred to orient the line passage  134  off axis. For example and without limitation, it is one preference of the invention that the line-passage  134  might be centered on the convex (torpedo-nose) end but below center on the flattened (and slanted) end. In all cases, it is preferred if the line-holes  134  and  136  are sized to allow for the sliding passage of fishing line  34  through them. The fishing line  34  terminates in a tag end  36  knotted to a fishhook  38  behind the skirt clamp  40 . Whereas the drawings show a knot, other attachment implementations are known in the art including without limitation devices which resemble crimp-on cable clamps (not shown) and the like. 
     The knotted tag end  36  (or whatever attachment implementation is utilized) and/or the fishhook  38 &#39;s eye prevents the hook  38  and line  34  from pulling through the line-holes of the lure  20 . 
     Given the foregoing, it is an aspect of the invention to provide a skirt clamp  40  as shown which can be undone from the body  22  (or just loosened) without having to cut the line. This advantage allows an angler to replace one skirt  30  for another skirt without the angler having to cut the line  34  to do so. Although only one skirt is shown in  FIGS. 2 ,  3   a  and  3   b  (see also FIGS.  8  and  12 - 13  in which two skirts are shown doubled-up). In other words, the lure  20  is arranged to allow one skirt  30  to be exchanged for another skirt: —while conveniently eliminating the need to cut off the line-tied hook  38  (again, only one skirt shown in  FIGS. 2-3   b , but see FIGS.  8  and  12 - 13  which show two skirts doubled-up). 
     It is an additional aspect of the invention that the inventive skirt clamp  40  securely clamps the selected skirt  30  to the lure body  22  to reduce chances of the skirt  30  being tugged back or indeed even being yanked off by short-striking fish. It is a further aspect of the invention that the inventive skirt clamp  40  secures the skirt  30  to the lure body  22  from inside the skirt  30  and not the outside and thereby not detracting from the streamlined contours of the transition between lure body  22  and skirt  30 . 
     The advantage of changing one skirt for another allows anglers to test the attractiveness of different skirt colors and styles rapidly, without having to cut the line. As mentioned, FIGS.  8  and  12 - 13  which show two skirts doubled-up. The advantage of two or more skirts doubled-up or whatever includes some of the same advantages. That is, it allows anglers to test different combinations of skirt colors or skirt styles in order to find what is attractive to fish. It being true for skirt colors too, skirt styles are available in almost endless variety. Whereas a skirt with straight tentacles is shown as a non-limiting example, another example could include and without limitation wavy tentacles, if not something other than tentacles altogether. 
     Another reason to change skirts or double-up skirts is to alter the swimming action of the lure  20 . That is, two skirts doubled-up are heavier than one skirt alone, but also two skirts together tend to increase the drag of the lure in the water. By way of background, skirts are available in a wide array of materials including without limitation vinyl, rubber (synthetic or natural), feather and so on. 
     The skirt clamp  40  comprises the form of a pan-headed fastener and has a shank  42  formed with external thread and a pan head  44  formed with an external bevel  46 . The axially-elongated body  22  has an interior ring portion  52  formed with corresponding internal thread, and the body  22 &#39;s trailing end  28  is formed with a corresponding interior bevel  54  so that the skirt clamp  40  secures and clamps the waist  32  of the skirt  30  from the inside as shown. 
     As a matter of more background, many off-the-shelf skirts (not shown) lack the waist  32  as shown by have spherical cap ends (again, this is not shown). It is a preference of the invention that anglers simply snip or lop such spherical cap ends off in order to modify such off-the-shelf skirts to exhibit a waist  32  as shown in the drawings. 
     This version of the cap  60  as illustrated by  FIGS. 1 through 6  has a cylindrical sidewall  62  formed with external thread that extends between a torpedo (domed) nose  64  and a plow (flattened and slanted) nose  66  (ie., the plow nose  66  is better shown by  FIGS. 5 and 6 , and is hidden from view altogether in  FIG. 1 ). The axially-elongated body  22  has a cylindrical fore chamber  58  formed with corresponding internal thread for screw insertion of the cap  60 .  FIGS. 3 through 6  comprise a series of views to show that this version of the cap  60  is reversible between its torpedo nose  64  and its plow nose  66  for transforming the lure  20  for different effects. In  FIG. 3  or  6 , the torpedo nose  64  is shown positioned to form the tip end of the lure  20 . The cap  60  is twisted into the axially-elongated body  22  as far as shown in order to get the following desired alignment: —that is, so that the torpedo nose  64  forms a fairly smooth transition with the axially-elongated body  22 &#39;s leading cup rim end  26 , which terminates in a relatively sharp taper as shown. 
       FIG. 4  shows a driving tool  70  in accordance with the invention. The driving tool  70  is provided for engaging and driving the cap  60  either deeper in to or withdrawal out of the axially-elongated body  22 . The driving tool  70  is also utilized for tightening and untwisting the skirt clamp  40  as well. The driving tool  70  has spaced prongs for engaging spaced recesses in the cap  60 &#39;s torpedo nose  64  as shown. Also, as  FIGS. 5 and 6  show, the cap  60 &#39;s plow nose  66  has comparable recesses, as does the pan head  44  of the skirt clamp  40  (eg., these recesses are shown in hidden lines in  FIG. 8 ). The prongs and recesses are cooperatively formed to prevent rotational slipping between the tool  70  and cap  60  (or skirt clamp  40 ) during twisting/untwisting use. Also, the driving tool  70 &#39;s prongs are preferably formed from sheetform material for the following purpose. That is, the fishing line  34  can lay along one side or another of the prongs without being nicked, damaged or otherwise compromised. 
     It is an aspect of the invention that the driving tool  70  can be utilized to drive the skirt clamp  40  or cap  60  without having to cut the line. Hence both the cap  60  and skirt clamp  40  can be completely separated from the body  22  of the lure  20  without having to cut the line in either instance. 
     Given the driving tool  70 , an angler can easily switch the cap  60  around as follows, and as depicted in  FIGS. 4 through 6 . To begin with, the angler withdraws the cap  60  fully from the body  22  as shown in  FIG. 4 . Next the angler reverses the cap  60  so that the plow nose  66  faces forward and as shown in  FIG. 5 . Then  FIG. 6  shows the cap  60  driven into the body  22  of the lure  20  so that this arrangement of the plow nose  66  being forward has transformed the lure  20 &#39;s swimming action. 
       FIGS. 3   a  and  3   b  show one way of varying the lure  20 &#39;s swimming action. With the torpedo nose  64  positioned as shown in  FIG. 3   a , the lure  20 &#39;s swimming action is preferably that of a torpedo-nosed type top-water lure. However, if the cap  60  is driven deeper into the body (as shown in  FIG. 3   b ), the tip end of the torpedo nose  64  can be virtually retracted flush with or perhaps rearwardly behind the front plane of leading cup rim end  26 . Hence this has the effect of transforming the lure  20 &#39;s mode of operation into that of a popping- or chugging type top-water lure. 
     Accordingly, the inventive lure  20  of  FIGS. 1 through 6  can be variously adjusted into several distinctive transformations, each which is distinguished by its own characteristic swimming action between four (4) extremes. 
     Pause will be taken to consider at least three swimming actions represented by the four (4) extremes (other swimming action are to be described more particularly further below). 
     First is the swimming action of the conventional torpedo-nosed topwater. This configuration for lure  20  is shown by  FIG. 3   a . Saltwater anglers prefer to troll these off an outrigger to surf the front side of a wake. At trolling speeds, torpedo-nosed topwater lures tend to skip on the surface. There are various factors which can vary skipping action, such as the pulse rate between skips, or the ratio for each pulse between how long (much time) the lure skims and how long (much time) the lure hops. Such factors include without limitation the weight and drag of the lure. 
     Next is the swimming action of concave-nosed topwater. This configuration for lure  20  is certainly shown by  FIG. 3   b . However, if in  FIG. 6 , if the cap  60  were driven deeper into the body  22  such that the plow nose  66  of the cap  60  were retracted flush with or perhaps rearwardly behind the front plane of leading cup rim end  26 , then, this too would be the configuration of a concave-nosed topwater. 
     Concave-nosed topwater lures tend to swim when trolled at speed with a porpoising action (ie., as in the graceful arcs swum by porpoises breaking the surface). 
     As an aside, freshwater anglers prefer not to troll but cast concave-nosed freshwater counterparts. Freshwater anglers general retrieve them with a tug-and-pause manner for a popping action. However, if retrieved with a continuous speed, freshwater anglers refer to the action as a ‘chugging’ action. 
     Referring again to the saltwater-trolled porpoising action, the lure  20  dives, then swims up, and breaks the surface. 
     Except, when the lure breaks the surface, it does so with a pop or splash (which is unlike porpoises). Then the lure arcs gracefully in the air for a low arc, and then dives again . . . and so on, doing this repetitiously. It is preferred without limitation to troll concave-nosed topwater lures behind the boat in the turbulence of the wake. Concave-nosed topwater lures tend to dive a shallow arc and then surface with a pop. How long they dive is sometimes a function of how much line is out. For trolling at longer lines, the dive tends to be longer between surfacing. 
     Again, it possible to configure the lure  20  for a concave-nosed configuration with either the torpedo nose  64  facing forward (and as shown in  FIG. 3   b ) or else with the plow nose  66  facing forward (not truly shown in  FIG. 6 , because the user would have to twist the cap  60  a lot further into the body  22 , but it is doable). 
     Then there is the swimming action of the slanted-nose topwater. This configuration for lure  20  is shown by  FIG. 6  as drawn. A slanted-nose topwater also tends to swim with a porpoising (chugging) action as before, but instead of porpoising on a straight path, it tends to dive and cut a helical path under the water. That is, it surfaces, leaps, then dives, and while diving it tends to cut a helical coil through the water until it surfaces again. Also, the surfacing is not characterized by the same amount of popping or splashing. Nevertheless, preferably but not exclusively, slanted-nose topwater lures are likewise trolled behind the boat in the turbulence of the wake. 
     Therefore, the lure  20  in accordance with the invention is variably changeable to provide at least the three foregoing swimming actions. That is, the lure  20  can be arranged to swim the skipping action of a torpedo-nosed topwater, the porpoising action of a concave-nosed topwater, or the helically-coiling porpoising action of a slant-faced topwater. 
     It is an aspect of the invention that the lure  20 &#39;s swimming action can be changed from a torpedo-nosed topwater (eg.,  FIG. 3   a ) to a concave-nosed topwater (eg.,  FIG. 3   b ) without having to cut the line. 
     It is an additional aspect of the invention that the lure  20 &#39;s swimming action can be changed from a slant-faced topwater (eg.,  FIG. 6 ) to a concave-nosed topwater without having to cut the line (ie., the cap  60  twisted into the body  22  such that the plow nose  66  is rearwardly behind the front plane of leading cup rim end  26 ). 
     In either  FIG. 3   a  or  6 , the way to change the lure  20  into a concave-nosed topwater is achieved by simply twisting the front cap  60  deeper into the lure body  22  until the cup-rim end  26  is the foremost part of the lure  20  facing forwards. That is, with the front cap  60  twisted deep inside the body  22 , it has little effect on the swimming again. Instead, the cup-rim front end  26  produces the greatest effect. And the cup-rim front end  26  provides a concave face for the lure  20 , with the front cap  60  sufficiently twisted rearwards so as not to provide any significant hydrodynamic effect on the lure  20 &#39;s swimming action ( FIG. 3   b  is an example of this configuration). 
     Moreover, the front cap  60  is retractable inside the fore chamber  58  of the body  22  to change the swimming action along a gradation of hybrid swimming actions. The gradation of hybrid swimming actions fall between the extremes of either skipping ( FIG. 3   a ) and porpoising ( FIG. 3   b ) or else between helically-coiling porpoising ( FIG. 6 ) and straight porpoising (not truly shown but the illustration of this extreme would be like  FIG. 6  but only if the cap  60  were twisted in a lot further). 
       FIGS. 7 and 8  show an alternate embodiment of the lure  80  in accordance with the invention for producing an adjustable bubbling/jetting effect in accordance with the invention. The axially-elongated body  82  is formed with a tail run  86  of a ventilation passage through its sidewall that extends from the fore chamber  58  to a termination in the skin of the sidewall as a side vent  88 .  FIG. 8  shows that a main and axial run  94  of the ventilation passage originates in an intake opening  92  on the mating line between the cap  84  and axially-elongated body  82 . The main axial run  94  extends through the respective thread formations of the cap and body  84  and  82  until the main run  94  intersects the tail run  86  that leads out to the side vent  88 .  FIG. 7  shows where the intake opening  92  is located with respective to the overall front geometry of the lure  80 . In use, the side vent  88  issues a stream of bubbles and/or water slugs intermittently with jets of water that not only leave a diminutive wake to the side of the main wake of the lure  80  (as the lure  80  courses its way along during a troll or retrieve), but also push the lure laterally in an erratic fashion. 
       FIGS. 9 and 10  show that the bubbling/jetting effect can be turned ON or OFF depending on the twist of the cap  84 . In  FIG. 9 , the cap  84  is twisted relative the body  82  to match up the mutual halves of the ventilation passage&#39;s main run  94  (ie., as formed in the meshing threads of the cap  84  and body  82  respectively). That way, with the main run  94  being formed as a matched-up passage, the main run  94  is thus “open” for business, and hence the bubbling/jetting effect is turned ON. In contrast,  FIG. 10  shows the cap  84  twisted a fraction of a turn counter-clockwise in order to mismatch the mutual halves of the ventilation passage&#39;s main run  94  (again, as formed in the meshing threads of the cap and body  84  and  82  respectively). Hence, with the mutual halves of the main run  94  being twisted out of alignment, the bubbling/jetting effect is thus turned OFF. 
     Needless to say the bubbling/jetting effect changes the swimming action of the lure. One, it produces a different wake for the lure. Two, it changes the straightness of the lure&#39;s tracking, and so on. 
     Hence the  FIGS. 8-10  lure has two sets of four swimming action extremes available to it with cutting the line (with all sort of gradation of hybrid swimming actions available too). 
     One set of four swimming action extremes available to the lure  80  without cutting the line includes:—
         torpedo nose, with side-jetting;   torpedo nose, without;   concave nose, with side-jetting; and   concave nose, without.       

     Correspondingly, the other set of four swimming action extremes available to the lure  80  without cutting the line includes:—
         plow nose, with side-jetting;   plow nose, without;   concave nose, with side-jetting; and   concave nose, without.       

       FIG. 11  shown an additional embodiment of the lure  100  in accordance with the invention. This additional embodiment of the lure  100  has a cap  110  that incorporates a source of illumination in order to produce an illuminated effect in accordance with the invention. It is preferred without limitation that the illumination effect be configured to give the lure  100  the resemblance of a creature with glowing or reflective eyes. 
     One way to achieve the illumination effect includes the incorporation within the cap  110  of one or more LED lamps  112  powered by one or more battery cells  114  connected up by a power circuit. Preferably the cap  110  is produced of transparent plastic. It may be painted with translucent paint to tint it to glow in a selected color. Alternatively, it might be painted with opaque paint generally all over except over the eyes. The turning ON and (perhaps OFF) of the power circuit can be achieved by a circuit-making plate  116  that is driven to make (ie., complete) the circuit by the twisting of the cap  110  deeper into the body  22  as an opposing compression spring  118  pushes the contact-making plate  116  harder against battery cells  114  that travel with the cap  110  as shown. 
       FIG. 12  shows a further embodiment of the lure  120  in accordance with the invention and as configured for producing a scent-issuing effect in accordance with the invention. The body  122 &#39;s fore chamber  58  is pre-charged with a scent concentrate  130  as shown. The lure  120 &#39;s cap  124 &#39;s central line-passing hole  134  might be oversized by some small measure (or not) in order to facilitate a greater intake current of water into the fore chamber  58 . Likewise, the skirt clamp  40 &#39;s central line-passing hole  136  might also be oversized by some small measure (or not) to increase the wash-out current from the fore chamber  58 . By way of being introduced by the line-hole  134  in the cap  124 , a water current is admitted in the fore chamber  58  and mixes with and carries out through the skirt clamp  40 &#39;s line-hole  136  some minute amounts of scent concentrate  130 . That way, the lure  120  trails behind itself a scent trail as the lure  120  courses its way along during a troll or retrieve. 
     It is another aspect of the invention that the recesses in the cap  124  for the prongs of the driving tool  70  might be drilled all the way through cap  124 . That way, scenting substance might be squirted inside the fore chamber  58  without the angler having to remove the cap  124 . 
       FIG. 13  shows yet another adaptation of the lure  120  in accordance with the invention to transform it for producing the combined effects in accordance with the invention of both the (unscented) bubbling effect in accordance with (eg.)  FIG. 8  and the scent-issuing effect of  FIG. 12 . 
     The lure  20  in accordance with the invention affords the opportunity for transformation for further effects as well, including without limitation inclusion of a rattle effect (not shown). That is, the fore chamber  58  allows the keeping of small BB rattles therein (not shown) to produce a rattle effect while the lure courses its way along during a troll or retrieve. 
     It is an advantage of the lure in accordance with the invention that it can be tuned for a variety of different topwater swimming actions after it has been fully rigged up and without having to cut (either) the main line or (leader line, if any). 
     Hence a preferred embodiment of invention has the front cap (eg.,  60 ) formed with one end presenting a torpedo nose  64  and the other end presenting a plow nose  66 . 
     Pause can be taken to consider the various ways the lure in accordance with the invention can be tuned for different swimming actions with the torpedo nose  64  leading. The various tunable positions include (and the resultant predominant-type swimming action or other effect caused thereby) the following, without limitation:
         torpedo nose more or less extended, hence more or less a skipping action; or   torpedo nose more or less retracted, hence more or less a porpoising action; and   either way, bubbling/jetting action that can be switched on or off; and/or   either way, variously interchangeable or combinable skirts;
 
wherein also, the other effects that can be included or excluded without limitation can be:
   inclusion or exclusion of a scent trail;   inclusion or exclusion of illumination; and/or,   inclusion or exclusion of a rattling noise.       

     In comparison, consideration can now be taken to consider the various ways the lure in accordance with the invention can be tuned for different swimming actions with the plow nose  66  leading. The various tunable positions include (and the resultant predominant-type swimming action or other effect caused thereby) the following, without limitation:
         plow more/less extended, hence more/less a helically-coiling porpoising action; or   plow more/less retracted, hence more/less a linear porpoising action; and   either way, bubbling/jetting action that can be switched on or off; and/or   either way, variously interchangeable or combinable skirts;
 
wherein also, the other effects that can be included or excluded without limitation can be:
   inclusion or exclusion of a scent trail;   inclusion or exclusion of illumination; and/or,   inclusion or exclusion of a rattling noise.
 
And so on endlessly, persons readily skilled in the art now being taught the concept of designing a lure which is alterable in many ways for different swimming actions and/or other effects which are selectable after the lure has been fully rigged up on the rod-reel-and-line combination: —and being able to do so without having to cut the (main) line (or leader line/s, if any). Whereas the drawings show a front cap (eg.,  60 ) having spaced ends formed as a torpedo nose and plow nose respectively, this has been done so for brevity&#39;s sake in the drawing and description since persons ordinarily skilled in the art can readily recognize that all the endless variety of lure noses can be executed in the designs of the spaced ends of the front cap (eg.,  60 ). For example and without limitation, one end of the front cap (eg.,  60 ) might present a scalloped plow nose (not shown). As another example and without limitation, one end of the front cap (eg.,  60 ) might present a concave front nose: —that way, when extended, the swimming action porpoises according to a minor-diameter concave face in contrast to when retracted the swimming action porpoises according to a major diameter swimming action.
       

     The invention having been disclosed in connection with the foregoing variations and examples, additional variations will now be apparent to persons skilled in the art. The invention is not intended to be limited to the variations specifically mentioned, and accordingly reference should be made to the appended claims rather than the foregoing discussion of preferred examples, to assess the scope of the invention in which exclusive rights are claimed.
