ALBERT L WING United States Patent Office 3,243,179 Patented Mar. 29, 1966 3,243,179 ROUTER TEMPLATE AND HOLDING MEANS THEREFOR Albert L. Wing, 1220 McKemy St., Tempe, Ariz. Filed Jan. 27, 1964, Ser. No. 340,464 7 Claims. (Cl. 269-873) This invention relates to a router template and holding means therefor, and, more particularly, to a routing template and holding means for use in routing various designed configurations in fiat panels or doors, or for routing holes therethrough for the insertion of Windows or the like.

In custom Cabinet work it has been a problem to provide a versatile and simple routing template and holding means therefor wherein a great variety of templates may readily be removably supported in connection with the holding means for guiding a router to form recessed designs in fiat panels or for routing openings in various doors such as kitchen cabinet doors or full height walkthrough doors, as desired.

It has heretofore been a problem to provide a versatile routing template and holding means therefor which may readily be attached to various doors in various areas thereof, and to also accommodate doors of varying thickness for the purpose of routing a great variety of ornamental designs in the faces of such doors or panels, or to rout openings therein to provide for the installation of windows.

Accordingly, it is an object of the present invention to provide a very versatile routing template and holding means therefor in which a frame is provided with opposed clamping means disposed to engage opposite edges of doors or panels for holding them in fixed relation to the template holding means so that a router may follow an opening in the template to cut a design in a panel or door or to rout an opening therethrough in conforming relation with the opening in the template.

Another object of the invention is to provide a novel template and holding means therefor wherein templates having various router guide designs may readily be connected to or removed from the holding means, and whereby a very versatile adjustable clamping means may permit a door or panel to be held in relation to the routing template in such a manner that the opening in the template may be located at various positions on the door or the panel as desired.

Another object of the invention is to provide a routing template and holding means therefor wherein the template holding means is provided with opposed portions having L-shaped clamping structures provided with ledges facing a template held by the holding means to hold one side of a door or a panel in juxtaposition with respect to a template removably held in the holding means.

Another object of the invention is to provide a routing template and holding means therefor in which the holding means is provided with opposed L-shaped clamps disposed to engage opposite edges of a door or panel and to engage one side thereof, said L-shaped clamps provided with spacers disposed to engage one side of a door or a panel to thereby compensate for the thickness thereof so that one side of the panel or door may be held in fixed spaced relationship at a predetermined plane with respect to the routing template.

Another object of the invention is to provide a routing template and holding means therefor wherein a template holding frame mounts a plurality of opposed clamping means having substantially L-shaped members engageable with one side of a panel and with opposite edges thereof, and wherein spacing means is provided between the frame and the mounting of the clamping means to provide for the accommodation of relatively thick doors between the clamping means and a predetermined plane spaced from the routing template.

Another object of the invention is to provide a novel routing template and holding means wherein the holding means is provided with spaced frame portions and clamping means on the spaced frame portions are opposed to each other and engageable with opposite edges of a door or panel, and wherein adjustable screw means is provided in relation to the frame for adjusting and holding the clamping means securely in engagement with opposite sides or edges of a door or panel for holding it in juxtaposition with relation to a template in the holding means of the invention.

Another object of the invention is to provide a routing template and holding means therefor wherein a pair of opposed clamping elements are engaged with the frame of the holding means of the invention and are opposed to each other and actuated by helical screws engaged by a disengageable nut segment and wherein the screws are slidably positioned in'bearings so that the screws may initially be freely reciprocated longitudinally of their axes in the bearings and thus roughly adjusted to engage opposite edges of a door or panel whereupon subsequent engagement of a nut segment with the screws maybe attained to provide screw threaded engagement of the screws relative to the frame holding means in order to provide for final tightening of the clamping means against opposite edges of a door or panel.

Another object of the invention is to provide a routing template and holding means therefor comprising a template supporting frame having a removable template connected therewith and having opposed screw actuated clamping means adapted to engage opposite edges of a door or panel; fiat portions on said screw disposed to present measuring indicia thereon provided to facilitate centering or locating of the panel or door between the clamping means with respect to the template holding means.

Another object of the invention is to provide a routing template and holding means therefor wherein the holding means comprises a frame having spaced elements and wherein clamping means is mounted on the spaced elements in opposed relation to each other to engage and clamp opposite edges of a door or panel on a fixed plane, and wherein spacers secured to the removable template of the invention outwardly of a router guide opening bear upon the panel or door held by the clamping means to support the template and prevent deflection thereof when a router is supported on the template and guided during the routing of design in the door or panel or during the routing of an opening therethrough, as desired.

Further objects and advantages of the invention may be apparent from the following specification, appended claims and accompanying drawings in which:

. FIGURE 6 is an enlarged fragmentary sectional view taken from the line 66 of FIGURE 1 showing a clamping screw structure of the invention and a disengageable screw threaded nut structure which permits simple rough adjustment of opposed door or panel clamps for engagement of opposite edges of such doors or panels and subsequent tightening of the clamping means to hold the door or panel in fixed position relative to the routing template of the invention; and

FIGURE 7 is a sectional view taken from the line 7--7 of FIGURE 6 and further illustrating the structure shown in FIGURE 6.

As shown in FIGURES 1 and 2 of the drawings, the routing template and holding means therefor comprises a frame 10 which may be substantially rectangular; this frame is provided with a pair of

end members

12 and 14, which are opposed to each other, and a pair of

side members

16 and 18, which are opposed to each other. These

frame members

12, 14, 16 and 18 are connected together at their corners by L-shaped blocks, as shown in FIGURE 5 of the drawings. These L-shaped blocks 20 are fitted into the hollow tubular structure of the

frame members

12, 14, 16 and 18, the cross section of which is shown in FIGURE 2 of the drawings. Screws 22 extend through a side wall of each of the

frame members

12, 14, 16 and 18, and into one of the blocks 20 in order to securely fix the frame members to the respective blocks 20.

Each block 20 is provided with a rib portion 24 which is disposed at substantially 45 degrees to the

legs

26 and 28 thereof, which are disposed at right angles to each other. This rib 24 extends outward to the full external dimenisons of the cross section of each

frame member

12, 14, 16 or 18 and forms a 45 degree abutment engaged by each respective end of each respective frame member, all as shown best in FIGURE 5 of the drawings.

In cross section all of these

frame members

12, 14, 16 and 18 are similar, and therefore the cross section of the frame member 14, as shown in FIGURE 2, will be hereindescribed.

The cross section of this frame member is substantially L-shaped, although it is hollow and thus the frame member 14 is provided with a recessed step 30 forming a ledge upon which a lower surface 32 of a routing template 34 rests. Thus an upper surface 36 of the routing template 34 is flush with an upper surface 38 of the cross section of the frame member 14, and likewise the upper surface 36 of the template 34; it is thus maintained flush with the remaining upper surfaces of all of the

frame members

12, 14, 16 and 18. The template 34 is readily removably mounted in the ledge structures 30, and thus the template 34 may be replaced as desired in order to select various router designed guide openings, such as the opening 40 disclosed in FIGURES 1 and 2 of the drawings. This opening 40 may be of any shape, and therefore it is desirable that a great number of templates may be provided for each holding frame, as hereinbefore described, so that a cabinet worker or someone routing designs or openings in panels or doors may select a great variety of designs and merely replace the template 34 according to the design opening required. This design opening 40, shown in FIGURE 2 of the drawings, is provided with an inner outline edge 42, which may be followed by a spindle guide 44 of a router 46, and the router 46 may be provided with a spindle 48 extending only a short distance inwardly of the upper surface 50 of a panel 52 for routing a design in the surface of the panel, or the router 46 may be provided with a long cutter 54 which may extend all the Way through the panel from its upper surface 50 to its lower surface 56; thus a window may be routed in the panel in accordance with the shape of the template opening 40.

The panel A shown in FIGURES 1 and 2 of the drawings is engaged at its upper surface 50 by spacers 58 secured by screws 60 to the template 34 so that the spacers 58 support the template 34 on the upper surface 50 of the door or panel in order to prevent downward deflection of the template 34 when the router 46 is supported thereon and routing design recesses in the surface 50 of a door or panel, or when the long cutter 54 is used to rout a window opening therethrough.

Opposite edge portions

62 and 64 are engaged by opposed L-shaped clamping means 66 and 68 each of which is connected to an adjusting screw 70, said adjusting screw being rotatable in a bearing portion 72 of the L-shaped clamping means 66, while a cross pin 74 maintains the enlarged head 76 of each screw captive so that the screw is rotatable relative to the L-shaped clamping means 66 and 68 to permit rotatable adjustment and tightening of the screws 70 relative to each of the L-shaped clamping means 66 and 68, as will be hereinafter described.

It will be seen that the clamping means 66 and 68 are opposed and that there are two pairs of them, shown in FIGURE 1 of the drawings, and that the clamping screw 70 holding these L-shaped clamping means 66 and 68 are all similar structures.

Each L-shaped clamping means 66 is provided with a surface 78 disposed to engage an edge of a door or a panel and is also provided with a ledge or face 80 disposed to engage a door or panel at the opposite side thereof from the side 50 adjacent to the template 34. Thus, the ledges 80 hold a door or panel in juxtaposition with relation to the spaces 58 and the template 34 and in position to be routed by either of the

routing cutters

48 or 54, as desired.

Each screw 70 is supported in a bearing 72, which may be internally screw threaded, or which may be a smooth bore structure with a disengageable nut, as will be hereinafter described. These bearings 72 may be connected directly with the

frame elements

12, 14, 16 and 18, as shown in FIGURE 2 of the drawings, or spacers 82 may be interposed between the bearings 72 and the frame members to provide a substantially great spacing of each clamp ledge 80 relative to end portions 84 of the spacers 58. Thus the structure shown in FIGURE 3 of the drawings provides for the holding of a relatively thick door or panel by reason of the mounting of the bearings 72 on the spacers 82 which are interposed between the frame elements and the clamping means bearings 72.

As shown in FIGURE 4 of the drawings, screws 86 secure a spacing block 88 to the face 80 of an L-shaped clamping means 66 or 68 so that the spacer 88 reduces the distance between the ends 84 of the spacers 58 and the clamping means to provide for holding a very thin door or panel to be routed adjacent the template 34.

The screws 70 are provided with square abutment thread portions 90 engageable by conforming threads 92 of a nut portion 94 integral with a lever 96 pivoted on a pin 98 and held normally in engagement with each screw 70 by means of a spring 100. Depression of the lever 96 in the direction of an arrow 102 causes the nut portion 94 to disengage from the square threads of the screw 70 and to permit the screw 70 to be slidably moved through its respective bearing 72 in order to make rough adjustments of the screws longitudinally of their axis to project the clamping means 66 and 68 into engagement with

opposite edges

62 and 64 of a door or panel A, whereupon engagement of the nut portion 94 of the lever 96 with the abutment threads of the screws 70 permit the screws then to be rotated by their respective crank'handles 104 to tighten them securely against opposite edges of the door or the panel so as to hold it firmly and securely in position adjacent the template 34 in juxtaposition for the routing operation hereinbefore described.

A narrow flat surface 106 disposed longitudinally 'of each "screw 70 is provided with measurement calibrations which may be read adjacent to each bearing 72 so that dimensional facilities are provided for sliding the screws 70 longitudinally of their axes either to center the door or panel A between the frame members of the template holding means or to precisely locate the opening 40 of the template in a required position relative to the door or panel A for the desired routing operation.

It will be seen that the bearings 72 are securely held to the frame members by screws 108, and these screws 168 may be relatively long as shown in FIGURE 3, or may be simply long enough to bolt the bearings directly to the frame members, as shown in FIGURES 2 and 4 of the drawings.

It will be obvious to those skilled in the art that various modifications of the invention may be resorted to in a manner limited only by a just interpretation of the following claims.
