DETAILED DESCRIPTION OF THE INVENTION

[0068] Referring specifically to FIGS. 2 and 3A-E, a template holder system 20 in accordance with one or more aspects of the invention preferably comprises a plurality of stands, or posts, 22 (preferably there are provided two such posts), and preferably a single cross member 24 interconnecting the two posts. The template holder system 20 may be comprised of a single post 22 and cross member 24, or more posts 22 may be employed as well, without departing from the true scope and spirit of the invention as claimed. However, it will be appreciated by those skilled in the art that two such posts is preferable from the standpoint of simplicity of use, rigidity and sturdiness of the resulting template guide system 20.

[0069] Each of the posts 22 of the template holder system 20 preferably has key slots, or grooves, 26 therein for facilitating alignment of the cross-member 24 thereon, for facilitating the adjustment of the template holder for use as described further hereafter for height adjustment, as well as for attaching the posts with bolts (four bolts for each post) to holes 55 in the router or pantograph mount 58 (FIG. 5).

[0070] The cross-member 24 of the template holder system 20 comprises measurement indicia 28 on an upper edge surface 7, and/or lower edge surface 5, thereon, either inch or metric scale, to assist with centering, or otherwise locating, a tapered template 30 on the template holder in order to allow correspondingly-located cuts on workpieces. Indicia 31 may also be provided on the posts 22 as well, in order to facilitate measurement of the cross member 24 and height guide 27 position, as discussed further below, relative to the posts 22.

[0071] The cross-member 24 of the template holder system 20 further preferably comprises three or more horizontal mounting grooves, or keyed slots, 29, made either of plastic or metal, such as aluminum. Each of the templates 30, 30 (as well as other templates described herein) have corresponding tapered tenons, or tapered tongues, 44 to help orient and fix the templates in the keyed slots. The taper of each of these orienting tenons 44, 44 is provided as slightly larger at a base of each tenon than at a tip of each tenon, as shown in FIG. 3D, so that upon placement and tightening of the template 30, 30 onto the template holder 24 as further described below, the templates are snugly attached fixed in the slots 29 of the template holder.

[0072] These tapered tenons 44 may be oriented longitudinally the length of the template 30 as shown in FIG. 3C, the keyed slots 29 are preferably spaced about inch, or about 20 mm, apart which provides optimal spacing for the templates 30, 30 in order to place single or multiple , , or thick mortise and tenon joints in dimensional lumber common to North America, such as 24, 26, 28, etc. The template holder 20 also accommodates non-tapered, tapered or stepped templates, as further described herein in accordance with one or more aspects of the invention, to make fixed or variably-spaced dovetail and box joints. The tapered templates 30 may be tapered on the exterior and interior surfaces to allow micro-adjustment of the joinery.

[0073] The template holder 20 further comprises an L-shaped side angle system 19 mounted, as with screws to each side of the template holder cross member 24, and the template holder cross member is partially retained within, and maintained squared relative to, the two L-shaped side angles by an outer vertically-oriented lip 11 on each L-shaped angle and engaging either end of the cross member. The L-shaped angle system 19, comprises left and right such L-shaped angles on either side of the template holder cross member. The L-shaped angles 19 and cross member 24, are removably fixed together with tightening screws so that the L-shaped angles and cross member combination is fixed together and adjustable as a unit, and alternatively able to be fixed, or locked at a certain height, relative to the posts 22 with the use of clamps 21, each clamp having a tightening lever 23.

[0074] The angles 19 and cross member 24 combination are able to be adjusted to an appropriate height according to indicia 31 on one of the posts 22, the workpiece used temporarily for a height measurement as further described below, or a representative sample workpiece of the same thickness as the workpiece. Thus, the system of clamps 21 each have a tightening lever 23 for the operator to actuate to adjust the template holder cross member 24 position relative to the posts 22, the pantograph carriage 58, and thus the workpiece, via the L-shaped angles 19 fixed to the template holder cross member.

[0075] Thus, there is also provided a height measurement clamp, or thickness gauge, 27 for holding a reference, or sample, workpiece/stock 3, to allow simple adjustment of the height of the cross member 24 and attached template 30 relative to the cross member, the routing table 58, and thus the actual workpiece on which cutting or carving is to be performed. The thickness gauge 27 allows the operator to quickly, accurately and easily center a cut or carving in the Y-axis of an actual workpiece (see FIG. 10 for an axis diagram for proper orientation for this specification).

[0076] This is accomplished by first referencing the upper surface of the thickness gauge 27 at the cutting table surface, and then by adding the sample/workpiece stock 3, followed by moving the cross member 24 (via the L-shaped angles sliding along the posts 22) down so that an underside of the cross member 24 comes to rest on the upper surface of the reference stock 3. Thereafter, the operator is able to fix the cross member 24 at that location using the levers 23 of clamps 21 which thus clamp the L-shaped angles 19 and attached cross member 24 to the posts 22 at the desired height. The thickness gauge 27 is built into the template holder system 20, preferably mounted on a template holder support post 22, or cross member 24. Thus the thickness of the workpiece or sample is measured by the gauge 27 to accurately position or center the joinery on the workpiece.

[0077] The clamps 21 are both for adjusting the template holder 20 and operating the cross member 24 and L-shaped angles 19 combination relative to the thickness gauge 27. The thickness gauge 27 is attached, and independently slides into, and is held in place within, the grooves 26 in the posts 22, via a screw 27a. The side angle assembly 19 must be aligned on entry into the groove 26 in the posts 22, and upon tightening of the clamp 21 via the lever 23. Therefore a part of the invention offsets the clamps 21 so one may be aligned at a time. This makes changing template holders 20 easier and faster. Thus the template holder and system 20, 21, 22, 24, 27, 30, 54, as well as inventive parts, combinations and other embodiments thereof, enables operators to more quickly and easily center the thickness (Y-axis) of a joint or shape in a workpiece. Thus, this aspect, or these aspects, of the invention helps users to more quickly and accurately center their work on an intended workpiece and allows for greater precision in cuts and carves.

[0078] Referring more specifically now to FIGS. 3A-E, there is provided one or more tapered templates 30 (other embodiments, including non-tapered templates, stepped templates, segmented templates, and other types of templates, are discussed hereafter in connection with other figures). Each tapered template 30 comprises a top portion 31, a base portion 33, and one or more continuously-tapered surfaces, exterior, outer continuously-tapered surface 32a, and interior, inner continuously-tapered surface 32b, interconnecting the top portion and the base portion of each tapered template 30. Each continuously-tapered surface 32a, 32b is continuously tapered in the sense that the surface has a continuous taper from the base portion 33 to the top portion 31. In the case of exterior continuously-tapered surface 32a, the taper preferably extends continuously inwardly from the intersecting edge 37 of the base portion 33 and the tapered surface 32a to the intersecting edge 39 of the top portion 31 and the tapered surface 32a. Similarly, in the case of interior continuously-tapered surface 32b, the taper preferably extends continuously outwardly from the intersecting edge 41 of the interior continuously-tapered surface 32b and the base portion 33 to the intersecting edge 43 of the interior continuously-tapered surface 32b and the top portion 31.

[0079] In this way, there is provided the ability for micro-adjustment of cuts and carves because of the fact that, to the degree there are provided tapered surfaces, they are adapted to interface in a continuously-tapered fashion with an adjustable guide bearing 54 (FIGS. 4a and 5) to allow for such continuously-adjustable micro-adjustment.

[0080] It will be appreciated by those skilled in the art that the templates described herein may be stadium-shaped, elliptical-shaped or some other shape as shown or described. The terms stadium and elliptical are used somewhat interchangeably herein when describing one or more of the figures. The stadium shape is a geometric figure consisting of a rectangle with top and bottom lengths a, and the ends of which are capped off with semi-circles of radius r. The area of a stadium is therefore given by A=r2+2ra, and the perimeter by p=2(r+a). While a stadium-shaped template, with a stadium-shaped outer periphery and a stadium-shaped inner periphery, or stepped inner periphery, is commonly, and even preferably employed in mortise and tenon joinery creation, it will be appreciated that other shapes, such as elliptical, circular, square, round, curved, or other shape appropriate to the desired design outcome, whether for joinery or otherwise, may also be employed with the present invention without departing from its true scope as claimed. Therefore, where stadium is mainly used herein to describe the shapes of the outer and inner peripheries of templates herein (and stadium may be interchangeably used with elliptical herein as pertaining to the drawings), it will be appreciated that elliptical, circular, square, or other basic shapes in accordance with a desired design outcome, whether for joinery or otherwise, may also be substituted without limiting the invention as claimed.

[0081] Each tapered template 30 is provided with a series of holes 45 adapted for receiving the key system 42 for use in releasably securing each template to the cross member 24 slot 29. The key system 42 further comprises a machine screw 47 preferably having an allen-wrench or screw driver slot(s) operable head 49 thereon. In this way, each tapered template 30 is adapted for interchangeable interconnection with a slot 29 of the cross member 24.

[0082] Each tapered template 30 is held on the slots 29 of the cross member 24 of the template holder 20 with the use of a releasably tightenable and adjustable key 42 and tapered tenon 44 system associated with each tapered template 30 as shown in FIG. 3E. The releasably tightenable and adjustable key 42 and tapered tenon 44 system may employ the use of multiple keys 42 as shown in FIG. 3E, or a single key 42 as shown in FIGS. 6 B-D. In either case, the tapered tenons 44, together with the key 42, serve to hold the tapered template 30 in aligned position on, and relative to, the template guide system cross member 24.

[0083] Referring now specifically to FIGS. 7A-B and 8A, in accordance with another embodiment and aspect of the invention, there are provided a plurality of segments 72, 74, 76 comprising together a tapered template 30. It will be appreciated that other types of templates, whether tapered, non-tapered, stepped, angular, or otherwise as discussed in other locations or in connection with other Figures in this specification, may be segmented and/or attached horizontally, vertically, or in angled orientation, to cross member 24 in accordance with an aspect and embodiments of the invention, without departing from the scope of the invention as claimed.

[0084] As with tapered template 30, tapered template 30, when considered with multiple segments fit together end-to-end, also comprises a continuous top portion 31, a continuous base portion 33, and one or more continuously-tapered surfaces, such as exterior, outer continuously-tapered surface 32a, and/or interior, inner continuously-tapered surface 32b, interconnecting the top portion and the base portion of each tapered template 30. Each continuously-tapered surface 32a/32b is continuously tapered in the sense that the surface has a continuous taper from the base portion 33 to the top portion 31. In the case of exterior continuously-tapered surface 32a, the taper preferably extends continuously inwardly from the intersecting edge 37 of the base portion 33 and the tapered surface 32a to the intersecting edge 39 of the top portion 31 and the tapered surface 32a. Similarly, in the case of interior continuously-tapered surface 32b, the taper preferably extends continuously outwardly from the intersecting edge 41 of the interior continuously-tapered surface 32b and the base portion 33 to the intersecting edge 43 of the interior continuously-tapered surface 32b and the top portion 31.

[0085] In this way, there is provided a tapered relationship not only between the exterior continuously-tapered surface 32a and the interior continuously-tapered surface 32b, but there is also provided for micro-adjustment of cuts and carves because of the fact that these tapered surfaces are adapted to interface in a continuously-tapered fashion with an adjustable guide bearing 54 to allow for such continuously-adjustable micro-adjustment.

[0086] In FIGS. 7A-B, tapered template 30 differs from tapered template 30 in that tapered template 30 is comprised of a plurality of segments 72, 74, 76. Thus, each of the segments 72, 74, 76 has a top portion 31, a base portion 33, an exterior continuously-tapered surface 32a, an interior continuously-tapered surface 32b, and preferably a hole 45, tapered tenons 44, and key members 42. Further, each tapered template segment 72, 74, 76 also preferably has at least one cross-section end cut 78, and in some cases (i.e., segment 74) a plurality of cross-section end cuts. Preferably, these cross-section end cuts 78 will match corresponding cross-section end cuts 78, so that two or more segments may be located end-to-end in the slots 29 of cross member 24 (as shown in dotted lines at 30 on FIG. 2) in order to form a complete template 30.

[0087] Thus, it will be appreciated that segments 72, 74, 76, or other segments having differing shapes in order to form desired cuts on a workpiece as will be appreciated by those skilled in the art, may be mixed, matched, and combined to form differing shapes and sizes of cuts. Thus, there is provided a router guide template 31, wherein the template is comprised of a plurality of segments of tapered templates 72, 74, 76. Further, each such segment 72, 74, 76 of tapered template 30 comprises a top portion 31, a base portion 33, and at least one of an exterior continuously-tapered surface 32a interconnecting the base portion and the top portion along an outer periphery and an interior continuously-tapered surface 32b interconnecting the base portion and the top portion along an inner periphery.

[0088] Still further, each such segment 72, 74, 76 of tapered template 30 further comprises two mating end portions 78 such that the plurality of segments of tapered templates may be removably and adjustably attached to the template holder 24 in end-to-end fashion. When combined in this manner, the top portions 31, the base portions 33, any exterior continuously-tapered surfaces 32a and interior continuously-tapered surfaces 32b of each segment 72, 74, 76 are mated end-to-end with an end 78 of another segment forming a continuous top portion 31, a continuous base portion 33, and one of an exterior continuously-tapered surface 32a and an interior continuously-tapered surface 32b between each mated segment.

[0089] When the entire plurality of segments 72, 74, 76 are thus mated end-to-end together they form a complete router guide template 30 with a continuous top portion 31, a continuous base portion 33, and at least one of an exterior continuously-tapered surface, 32a, an interior continuously-tapered surface 32b, and even a non-tapered interior or exterior surface (e.g., for example if template 81 or 83 of FIG. 8 were to be shown as segmented, since there are not shown guide surface tapers on these templates). This aspect of the invention further supports and enables greater ease and flexibility in forming templates 30 to accomplish a wider range of joining, or decorative, cuts in a workpiece.

[0090] Each tapered template 30 (30, 30, 30, 80, 81, 83, 90, 92, etc.) is provided with a series of holes 45 adapted for receiving the key system 42 for use in releasably securing each template to the cross member 24 slot 29. The key system 42 further comprises a threaded post 47 preferably with an allen-wrench (other screwdriver) operable head 49 thereon. In this way, each template is adapted for interchangeable interconnection with a slot 29 of the cross member 24.

[0091] It will be appreciated that any taper of the interior and the exterior tapered surfaces of the templates (e.g., 30) described herein, may beneficially extend along the entire tapered surface (depending upon the desired output of such a guided pantorouter system), both from the base portion (e.g., 33) of the template to the top portion (e.g., 31) of the template, as well as around the entire length, or circumference in the case of an entirely stadium, elliptical, circular or oval template. Thus, there may be advantageously provided such a taper both near the top portion (e.g., 31) of the template (e.g., 30), near the base portion (e.g., 33) of the template, in between these two extreme locations, and along the entire tapered length of the template.

[0092] Referring now to FIGS. 6A-D, there is provided an alternative embodiment template 30, comprised of a stepped, tapered template 30, wherein, similar to tapered template 30, there is provided a top portion 31, a base portion 33, an exterior continuously-tapered surface 32a, and stepped interior surfaces 32b and 32c. Further, as with template 30, and 30, template 30 also comprises alignment tapered tenons 44, and a key system 42, except unlike the key systems 42, 42 of templates 30, 30, respectively, template 30 only has a single key system 42, which together with the alignment tapered tenons 44, serves to releasably hold the template 30 on a cross member 24 slot 29.

[0093] In FIG. 6D, there is provided yet another alternative embodiment template 30, comprised of a stepped, tapered template 30, wherein similar to tapered template 30, there is provided a top portion 31, a base portion 33, an exterior continuously-tapered surface 32a, and stepped interior surfaces 32b and 32c. However, unlike tapered template 30, interior surfaces 32b and 32c are tapered at each of the steps. Like tapered template 30, tapered template 30 also comprises alignment tapered tenons 44, and a key system 42 for releasably holding the template 30 on a cross member 24 slot 29.

[0094] Referring now to FIGS. 8A, 8B, and 8C, there are provided alternative templates 80, 81, 83, respectively. Each such template has a key system 82 similar to that of tapered template 30, for example, and tapered tenons 84, 88, 85, respectively as to FIGS. 8A, 8B, 8C. Because of the orientation of the tapered tenons 84, the segmented template 80 would sit vertically on the cross member 24 similar to segmented template 80 shown in dotted lines on FIG. 2, whereas the template 81 would sit at an angle on the cross member 24, and the template 85 would sit horizontally on the cross member 24.

[0095] Referring now also to FIGS. 4a and 5, the invention uses a router motor 50 (as part of a PantoRouter, or Hybrid PantoRouter, router system 49), having a router bit 52 and guide bearing, or guide wheel, 54 held on a guide bearing shaft 83 on a pantographic mount 56 on a base or carriage 58. On the pantographic mount 56, the center of the guide bearing 54 is located twice the distance from the reference pivot as the center of the router bit 52. The guide bearing 54 is guided by the operator around or within a template 30, 30, 30, 30, 80, 81, 83, 90, 92 moveably located in the moveable tapered template holder system 20. Using the handle 51 and arm 53 of the pantographic mount 56, the operator can move the guide bearing 54 up or down the tapers 32a, 32b of the tapered template 30, or tapers 32a, 32b of the tapered template 31, etc., which creates a larger or smaller cut in the workpiece by the router bit 52. In this way, and by adjusting the depth of the guide bearing 54 on a taper on a template via guide bearing adjustment knob 81, the operator is allowed in micro-adjusting the size of the cut or carve on a workpiece.

[0096] Of course, it will be appreciated by those skilled in the art that templates such as those shown in FIGS. 9a and 9b may be adapted for use with all other aspects of the invention, since these templates may be adapted in accordance with this disclosure to include tapered tenons and keys for interconnecting to a template holder as per an embodiment and aspect of the invention. Thus, the template 90 shows an alternative embodiment of a template comprising an exterior stepped portion and an interior stepped portion (without showing, for purposes of avoiding redundancy, tapered tenons and keys for interconnecting to a template holder as per an embodiment and aspect of the invention). Moreover, the template 92 shows a template comprising an exterior stepped portion and an interior non-tapered portion (again without showing, for purposes of avoiding redundancy, tapered tenons and keys for interconnecting to a template holder as per an embodiment and aspect of the invention).

[0097] In accordance with an alternative embodiment of the invention as shown additionally in FIG. 4B, guide bearings can also be tapered as shown at 54 to be used with stepped templates (e.g., 30 of FIG. 6B, or 90 of FIG. 9A), non-tapered templates 30, tapered templates (e.g., 30 of FIGS. 3A-E), or segmented templates (e.g., 30 of FIGS. 7A-B and 80 of FIGS. 8A and 2), to also allow micro-adjusting the size of the cut or carve on a workpiece.

[0098] The invention, or certain aspects thereof, can be used in any position, including but not limited to horizontal, such as with a Hybrid PantoRouter and PantoRouter, or vertical such as a pin router or similar application. The invention, or certain aspects thereof, can also be used with non-pantographic router mount devices. Thus, the template holder system in accordance with an aspect of the invention can be moved to different positions, different jigs, or with different machines.

[0099] The tapered-template system in accordance with an aspect of the invention addresses problems of safety, inaccurate joinery using a router and fixed-size guides or templates. Thus, the invention enables quick, accurate, safer and easy-to-make joinery cuts, whether dovetail, mortise and tenon, or box joint cuts.

[0100] Further, the tapered-template system in accordance with an aspect of the invention allows for easy and quick micro-adjustments to cuts and carves, and thus certain aspects of the invention enable quick, accurate and easy-to-make micro-adjustments to a proposed cut. With the use of the template system (whether with non-tapered, tapered, or stepped templates) in accordance with one or more aspects of the invention, operators are enabled in greater control over routers using a pantographic router mount in order to make routers safer, easier to use and more accurate. The tapered template system in accordance with an aspect of the invention enables operates in installing and changing templates and template holders, thus facilitating the work of setting up, creating, and taking down, a project.
