CROSS-REFERENCE TO RELATED PATENT APPLICATIONS 
     This patent application is a continuation of U.S. patent application Ser. No. 11/956,536, filed Dec. 14, 2007, now U.S. Pat. No. 7,766,059, the entire teachings and disclosure of which are incorporated herein by reference thereto. 
    
    
     FIELD OF THE INVENTION 
     This invention generally relates to routing mortises for mounting hinges and strike plates to door edges, and more particularly to tools and kits for assisting in routing mortises for mounting hinges and strike plates to door edges. 
     BACKGROUND OF THE INVENTION 
     To improve the functionality and aesthetic appearance of door hinges and strike plates, do-it-yourself woodworkers (DIYs) typically recess the hinge or strike plate in a side of the door so that the hinge or strike is flush with the side of the door (also referred to as “flush mounted”). To flush mount the hinge or strike plate, a mortise is formed at the desired location along the side of the door. A router is one efficient and timely way to form the mortise. 
     DIYs will typically use a guide or template to guide the router as the mortise is formed. The template is nailed to the door in the appropriate location to form the mortise. However, as door thicknesses and heights vary, the orientation of the template relative to one door may be different with regard to a second door, such as a door having a larger thickness. Several representative templates for forming these mortises include the “Strike &amp; Latch Template” having model number 59375 and “Door Hinge Template” having model number 59375 of Delta Porter-Cable, headquartered in Jackson, Tenn. These templates include removable locating pins that can be used to adjust the alignment of the templates relative to the thickness of the door. The pins extend through apertures in the template. The template includes numerous apertures that are offset from one another such that one aperture is used for a door of a first thickness, such as two inches, while a second aperture is used for a door of a second thickness, such as 2.25 inches. 
     The present invention relates to improvements in such templates for forming the mortises for locating and flush mounting door hinges and strike plates.

On the contrary, the intent is to cover all alternatives, modifications and equivalents as included within the spirit and scope of the invention as defined by the appended claims. 
     DETAILED DESCRIPTION OF THE INVENTION 
       FIG. 1  illustrates a first embodiment of a mortise template kit  100  in accordance with the present invention. A mortise template kit may also be referred to herein as “the kit” or “the template kit”. The kit  100  generally includes a template holder  102  and a plurality of mortise templates  106 - 113 . The mortise templates  106 - 113  may also be referred to herein as “the template” (when referring to a specific template) or “the templates” (when referring to a plurality of the templates). The kit  100  is illustrated with an optional alignment schedule  115  illustrated schematically in  FIG. 1  for locating the various templates  106 - 113 . 
     With additional reference to  FIG. 2 , the template holder  102  is mounted to a door edge  116  of door  118 . The template holder  102  includes template  108  secured thereto to form guide  124 , which is used herein to refer to the combination of the template holder  102  and one of templates  106 - 113 . The guide  124  provides a guide for forming and locating a mortise  125  in the door edge  116 . The mortise  125  will be similar to the other two mortises  122 ,  123  previously formed in the door edge  116  using the template holder  102  and template  108 . 
     Typically, the user will use the guide  124  to directly guide a router (not shown) as the mortise  125  is milled into the door edge  116 . However, the guide  124  could be used to merely scribe or otherwise mark an outline of the mortise  125  which will be subsequently formed by removal of the door edge  116  by another tool such as a chisel (not shown). 
     With reference to  FIG. 3 , the template holder  102  includes a frame portion  128  that forms a mounting aperture  130  and a pair of leg portions  132 ,  134  that each terminate into a foot portion  136 ,  138 , respectively. The leg portions  132 ,  134  are configured to offset the feet  136 ,  138  from the frame portion  128  in a direction extending generally parallel to the direction at which the mounting aperture  130  extends through the frame portion  128 . 
     The feet  136 ,  138  include apertures  140 ,  142  through which a nail  143  (see  FIG. 2 ) or other tacking device passes when the template holder  102  is secured to a door edge  116 . The apertures  140 ,  142  are positioned on opposite sides of the mounting aperture  130  and extend through the template holder  102  generally parallel to the mounting aperture  130 . 
     The template holder  102  is preferably a unitary body formed from a single piece. More preferably, the template holder  102  is preferably a piece of stamped metal. However, the template holder  102  could be formed from plastic materials. Further, the template holder  102  could be formed from multiple pieces. 
     Adjustment mechanisms, in the form of knobs  146 ,  148  connected to cams  150 ,  152 , permit the template holder  102  to be easily adjusted for use with doors having varying thicknesses t. The cams  150 ,  152  rotate with knobs  146 ,  148  relative to the template holder  102 . 
     Knobs  146 ,  148  include shafts  166 ,  168  that pass through shaft apertures  170 ,  171  passing through feet  136 ,  138  generally parallel to mounting aperture  130  and connect to cams  150 ,  152 . The shafts  166 ,  168  insert into the shaft receiving cavities  172 ,  173 . The shafts  166 ,  168  and shaft receiving slots  172 ,  173  are non-round and configured such that the shafts  166 ,  168  do not rotate relative to the cams  150 ,  152 . Shaft apertures  170 ,  171  generally define axes  174 ,  175  about which the knob and cam combinations rotate. 
     The cams  150 ,  152 , as illustrated, are substantially identical. With reference to  FIG. 4 , which only illustrates cam  150 , cam  150  has a non-uniform outer periphery that includes three abutments in the form of generally planar surfaces  156 - 158 . One of the surfaces  156 - 158  abuts against a door side  162  while the a guide  124  is mounted to a door edge  116  to properly position the template  106 - 113  of the guide  124  about the thickness t of the door  118 . The surface  156 - 158  that is used to abut the door side  162  of a given door depends on the thickness t of the door  118  or whether a strike plate or latch plate is being installed. 
     The surfaces  156 - 158  of cam  150  are spaced varying radial distances R 1 , R 2 , R 3  (extending generally perpendicularly to the plane defined by the surfaces  156 - 158 ) from the axis of rotation of the cam  150 . The varying distances R 1 , R 2 , R 3  allow for adjustment relative to the thickness t of a door  118 . 
     Referring again to  FIG. 3 , the knobs  146 ,  148  include projections  176 ,  177  that insert into locating apertures  178 ,  180  in the feet  136 ,  138  to lock the angular orientation of the knobs  146 ,  148 , and consequently cams  150 ,  152 . 
     The adjustment mechanisms further include coil springs  182 ,  183  that mount about shafts  166 ,  168  and bias the cams  150 ,  152  away from the feet  136 ,  138  and the knobs  146 ,  148  toward feet  136 ,  138 . The coil springs  182 ,  183  retain the projections  176 ,  177  in a selected one of the locating aperture  178 ,  180  depending on the desired orientation of the cams  150 ,  152 . The coil springs  182 ,  183  of the present invention are interposed between the cams  150 ,  152  and the feet  136 ,  138 . Pulling on the knobs  146 ,  148  compresses the coil springs  182 ,  183  and removes the projections  176 ,  177  from the selected locating aperture  178 ,  180  such that the knobs  146 ,  148  can be rotated to alter the orientation of the cams  150 ,  152 . 
     Other structure can be used to maintain the orientation of the knobs  146 ,  148  and cams  150 ,  152  relative to the template holder  102 . For example, the projections could extend from the feet and the knobs could include corresponding apertures. 
     Because hinges, strike plates and latch plates for doors may vary in shape, size or configuration, the templates  106 - 113  include templates for varying sized and shaped door components. The illustrated templates  106 - 113  are merely representative templates of an embodiment of kit  100 . However, other templates could be included in practicing kits of the present invention. The illustrated kit  100  includes templates for forming mortises for hinges, namely templates  106 - 110  as well as templates for forming mortises for strike plates or latch plates, namely templates  111 - 113 . 
     Each template  106 - 113  generally includes a top plate  186  and a mounting flange  187  extending outward from the top plate  186 . A template aperture  188  extending through the top plate  186  that is generally surrounded by the mounting flange  187 . The mounting flange  187  is closely sized to the mounting aperture  130  of the template holder  102 , such that limited slop is provided between the template holder  102  and an inserted template  106 - 113 . The mounting flange  186  preferably includes outer projecting nibs  189  that extend perpendicular to the template aperture  188  and that are spaced apart from the top plate  186  forming a gap  190  therebetween. 
     The nibs  189  permit snap-fit engagement between the templates  106 - 113  and the template holder  102  such that the templates  106 - 113  can be easily connected to and disconnected from the template holder  102 . The frame portion  128  of the template holder  102  is received in the gap  190 . 
     As illustrated, nibs  189  extend outward from all four sides of the mounting flange  187 . However, in other embodiments, the mounting flange  187  could be configured with nibs on fewer sides. 
     The top plate  186  is sized larger than the mounting aperture  130  of the template holder  102  such that a portion of the top plate  186  rests against the frame portion  128  when a template  106 - 113  is mounted to the template holder  102 . 
     The top plate  186  is generally rectangular-shaped. In the illustrated embodiments, each side  192 ,  193  of a pair of opposed sides of the top plate  186  of templates  106 - 113  includes a tab engagement slot  194 ,  195 . The tab engagement slots  194 ,  195  are configured to be engaged by a tab of a tape measure for assisting in locating the guide  124  along the length of the door  118 . In the illustrated embodiments, the tab engagement slots  194 ,  195  are formed between pairs of outward extending tabs  196 . As illustrated, in a preferred embodiment, the tab engagement slots  194 ,  195  open away from one another and extend entirely through the top plate  186 . 
     The tab engagement slots  194 ,  195  are preferably between about two hundredths and one-quarter inches and more preferably between two hundredths and fifteen hundredths of an inch in width W and between one-eighth and three-quarter inch in depth D 1 . 
     As illustrated, the tab engagement slots  194 ,  195  are generally positioned at and identify the center of the template aperture  188 . As such, an axis aligned with both tab engagement slots  194 ,  195  of a template  106 - 113  preferably bisects an individual template aperture  188 . 
     Also, a plurality of the templates, including the hinge templates  106 - 110 , are reversible such that the templates can be used for different types of hinges, strike plates, or latch plates. For example, template  106  is a hinge template and includes a generally rectangular shaped template aperture  188 . However, the corners  197 ,  198  at the opposed ends of side  200  of the template aperture  188  have a larger fillet radius R 4  than corners  202 ,  204  at the opposed ends of side  206 . As such, the template  106  can be used in the template holder  102  in a first orientation to provide mortises having larger radius corners (i.e. using corners  196 ,  198 ) and a second reversed orientation to provide mortises having small radius corners (i.e. using corners  202 ,  204 ). The radius R 4  of the large fillet corners  196 ,  198  is preferably between about three-eighths and three-quarter inch and the radius of the small fillet corners  202 ,  204  is preferably between about zero inch (i.e. no radius/chamfer) and one-half inch. However, other small and large radiuses are contemplated. To accommodate the varying orientation of the templates, the outer periphery of the mounting flange and the mounting aperture of the template holder are 180 degree rotation symmetric. 
     The templates  106 - 113  are preferably made as unitary one piece body. More preferably the templates  106 - 113  are formed of plastic, and even more preferably from injection molded plastic. 
     A typical hinged door for entry into a room will have three hinges. Thus, the door will include three mortises in the door edge. As illustrated in  FIG. 2 , door  118  is configured to have three door hinges and thus includes three mortises  122 ,  123 ,  125 . Two mortises  122 ,  123  have already been formed in door edge  116  and the guide  124  is positioned for forming the third mortise  125 . 
     Doors typically come in standard lengths, L, of approximately eighty inches, eight-four inches or ninety-six inches. Further, door hinges are typically placed at standard distances from the ends of the door and from each other. As such, it is typical to place a first mortise  122  mortise proximate the top  210  of the door  118  a distance D 2  of approximately seven inches from the top  210  of the door  118  to the first edge of the hinge or mortise  122 . A second mortise  125 , the mortise for the bottom hinge, will typically be a distance D 3  of approximately eleven inches from the bottom  212  of the door  118  measured to the first edge of the hinge or mortise  125 . A third mortise  123  is interposed between the top and bottom mortises  122 ,  125  and typically evenly spaced between the top and bottom mortises  122 ,  125 , illustrated by distances D 4 . 
     Kit  100  of the present invention facilitates quick and accurate placement of the mortises  122 ,  123 ,  125 . More particularly, in an embodiment, the kit  100  includes an alignment schedule  115  (illustrated schematically in  FIG. 1 ). The alignment schedule  115  includes alignment data for placing the guide  124  along the door edge  116  when forming mortises  122 ,  123 ,  125 . In a preferred embodiment, the alignment schedule  115  includes alignment data that includes the distance from either the door top  210  of the door bottom  212  to a corresponding marking point on the template  106 - 113  or template holder  102  so that the guide  124  can be quickly and accurately positioned along the door edge  116 . These distances are illustrated as D 5 -D 7  in  FIG. 2 . In one embodiment, the alignment schedule  115  includes alignment data for the three standard door lengths of eighty inches, eighty-four inches, and ninety six inches. The alignment schedule preferably provides the distance for each of the three mortises  122 ,  123 ,  125  for all three standard door lengths for hinges ranging from two and a half inches to four and half inches in one-half inch increments. 
     With reference to  FIG. 6 , the guide  124  can be used to form corresponding mortises  224 ,  223 ,  225  in a sill of a door frame  218 . The alignment schedule  115  may include alignment data for locating these mortises  224 ,  223 ,  225  as well. For example, schedule  115  may include distanced D 8 -D 10  which provide alignment data for positioning the guide  124  from the top of the door frame  218 . 
     Table 1 provides an example of an alignment schedule that may be included with a kit  100  according to the teachings of the present invention. The alignment data refers to the distance from the top  210  of the door  118  to the tab engagement slots  194 ,  195  (i.e. the center of the corresponding template  106 - 113 ).

     The following example will illustrate how the alignment schedule  115  and guide  124  is used. The example will best understood with reference to  FIGS. 2 and 6 . To form the mortises required for an eighty-four inch door using three and one-half inch hinges, the user can measure a distance D 5  from the top edge of the door  118  to the tab engaging slot  195  eight and three-quarter inches and form the first mortise  122  at a distance D 2  of seven inches from the top of the door. The user would tack the guide  124 , including template  110 , to the door edge  116  and then route mortise  122 . Next, the user would locate guide  124  along the door edge  116  with the tab engagement slot  195  a distance D 6  of forty-three and one-half inches from the top of the door  118  and then form the mortise  123 . The user would locate guide  124  along the door edge  116  with the tab engagement slot  195  a distance D 7  of seventy-one and one-quarter inches from the top of the door  118  and then form the final mortise  125 . 
     Then, the user would do the similar actions on the inside of the door frame  218 . The user can measure a distance D 8  from the top edge of the door frame  218  to the tab engaging slot  195  eight and seven-eighth inches and form the first mortise  224 . The user would tack the guide  124 , including template  110 , to the door frame  218  and then route mortise  224 . Next, the user would locate guide  124  along the door frame  218  with the tab engagement slot  195  a distance D 8  of forty-three and five-eighth inches from the top of the door frame  218  and then form the mortise  223 . The user would locate guide  124  along the door edge  116  with the tab engagement slot  195  a distance D 9  of seventy-one and three-eighth inches from the top of the door frame  218  and then form the final mortise  225 .
