Abstract:
A lock installation system of template drill and router guides that clamp to the door to prepare doors for locking and latching devices of many different brands. The system uses changeable template drill guides clamped to the faces of the door to drill the cross hole and other specialty holes needed. The edge drilling is done with an attachment for the proper size bit or with a ¼ inch pilot hole and hole saw. The attachment also allows the pre-drilling of the screw holes for mounting the latch assembly. After removing the edge drill setup, there is a router template to cut the mortise for the latch for commercial locksets. There is an attachment for residential locks to router cut the mortise cut out for the latch assembly. The embodiment will work on beveled and square edge doors of the two most common back sets. The embodiment will do door edge center, off set drilling and latch assembly mortising. There is also a means to help align the embodiment on a door that has a pre-existing preparation. The smaller version of this embodiment is for where the door edge latch mortising is not required.

       BACKGROUND OF THE INVENTION 
       [0003]    1. Field of the Invention 
         [0004]    The present invention deals with the field of devices usable for facilitating the cutting of holes in the face and the edge of doors for the placement of tubular style lever sets, knob sets, locksets, deadbolts, stand alone electronic and mechanical access control locksets and other types of locking and latching mechanisms therein. 
         [0005]    Generally there are three methods of installing lock mechanisms on the door with the first being to hand measure all specifications of the lock to be installed on to the door. This is slow and mistakes are not uncommon. The second method is to use the paper template that comes with the lockset as this is faster and less chance of mistakes when taped to the door but paper templates are not always accurate because of printing problems and they are not always properly positioned on the door. Both hand measuring and template require the use of hand tools that are generally slower and less accurate. Often only one side of the door is marked and the hole(s) are not squarely drilled through the door and thus creating problems with the installation. The third method is to use a jig or a series of jigs for cutting the holes and although it is faster and more accurate than the hand measuring or paper templates, there has not been one single jig to do a total door lock preparation or to fix miss drilled doors. The present invention provides a novel means for fast and accurate drilling and routing of all the necessary holes and cut outs in the door in one setup with less chance of damage to the door for modern style tubular locksets. 
         [0006]    2. Descriptions of the Prior Art 
         [0007]    Numerous attempts have been made to create drilling and routing jigs for door lock installation however none have proved to be as universal and simple to use as the present embodiment as the listed prior art below prove. 
         [0008]    Some examples of prior art are shown with U.S. Pat. No. 4,445,227 from May 1, 1984 by Keefe that shows a jig that can be programmed for many applications but would have trouble with the modern lever locks and access control locksets because of the number of holes required and their location. It would also be easy to make mistakes with this jig. U.S. Pat. No. 6,343,632B1 from Feb. 5, 2002 by Zivojinvic is a jig that can be used for mortise and cylindrical lock preparation and does use template plate drill guides on the faces of the door however is most suited for mortise lock preparation and does not provide a means to pre-drill the latch plate mounting screws. 
         [0009]    General mortising jigs that can be used for some parts of lock installation can be seen in U.S. Pat. No. 1,762,457 from Jun. 10, 1930 by L. Uhrin and U.S. Pat. No. 2,663,335 from Dec. 22, 1953 by W. H. Gohm, Sr. and also in US Pending Patent number US2009/0272463A1 from Nov. 5, 2009 by Smith for use with a drill motor. 
         [0010]    There are template jigs for adding specific holes however they are not for total lock preparation as in U.S. Pat. No. 7,481,607B2 from Jan. 27, 2009 by Rusiana et al is a template system for hospital paddles to only add 4 holes with different backsets. U.S. Pat. No. 5,915,891 from Jun. 29, 1999 by Friedman is a template for only one side of the door for extra holes for lever locks. U.S. Pat. No. 5,222,845 from Jun. 29, 1993 by Goldstein et al is for edge hole and cross drill for 2¾ inch backset with changeable plates with template drill guides for specialty holes with a plate only on one side of the door and when the drill brakes through the door, the drill is likely to splinter the wood from the unsupported hole unless the jig is removed and turned over and reinstalled. The jig has no means of providing latch plate mortising and pre-drilling of screw holes. The jig is not easily adjustable for backset and will not allow for easy re-drilling of a miss drilled door. US Pending Patent number US2007/0227016A1 from Oct. 4, 2007 by Tarter is a template system for mortise lock trim holes on both sides of door and does not do any door edge drilling or mortising. 
         [0011]    There are many lockset installation jigs of many different configurations and variations that do only the main cross drill and edge drill however do not do latch mortising or specialty holes. U.S. Pat. No. 7,356,902B2 from Apr. 15, 2008 by Snider et al has adjustable backset and door thickness and is made of plastic for low usage with no specialty holes or latch mortising U.S. Pat. No. 7,530,770B2 from May 12, 2009 by Chao is self adjusting for door thickness and is a hole saw drill guide with no specialty holes or latch mortising US Pending Patent number US2003/0172535A1 from Jul. 18, 2003 by Grizzle is a template for cross and edge drilling made from a plate with a 90 degree bend screwed to the door. The jig only guides the drill from one side of the door and does not do specialty holes or latch mortising US Pending Patent number US2004/0240950A1 from Dec. 2, 2004 by Trettin et al and US Pending Patent number US2004/0062618A1 from Apr. 1, 2004 by Trettin et al, these two pending patents appear to be the same jig and are a hole saw drill guide for one side of the door screwed to the door with the latch screws and is made of plastic. This design would be for low usage and does not do specialty holes or latch mortising. US Pending Patent number US2004/0020809A1 from Feb. 5, 2004 by Allan et al and US Pending Patent number US2005/0072701A1 from Apr. 7, 2005 by Allan et al are wrap around template kits for only the cross drill and edge holes and does not do specialty holes or latch mortising. US Pending Patent number US2005/0129472A1 from Jun. 16, 2005 by Liu et al is a hole saw drill guide for only cross drill and edge holes and does not do specialty holes or latch mortising US Pending Patent number US2005/0220548A1 from Oct. 6, 2005 by Thomas is a hole saw drill guide for only one side of the door and for only cross drill and edge holes and does not do specialty holes or latch mortising. US Pending Patent number US2005/0220549A1 from Oct. 6, 2005 by Thomas is only for cross drill and edge drill guide for only one side of the door and does not do specialty holes or latch mortising. US Pending Patent number US2007/0041800A1 from Feb. 22, 2007 by Santos is only for cross drill and edge drill guide from both sides of the door. This jig screws to the door with the latch screws with an unusual backset adjustment and is made of plastic and does not do specialty holes or latch mortising US Pending Patent number US2007/0189868A1 from Aug. 16, 2007 by Snider et al is only for cross drill and edge drill guide for both sides of the door and is made of plastic and does not do specialty holes or latch mortising US Pending Patent number US2007/0110528A1 from May 17, 2007 by Chao is only for cross drill and edge drill guide and is made of plastic and does not do specialty holes or latch mortising. U.S. Pat. No. 2,792,727 from May 21, 1957 by B. A. McCuen is hand operated and is only for the cross drill and edge drill holes and does not do specialty holes or latch mortising U.S. Pat. No. 2,886,989 from May 19, 1959 by B. A. McCuen is hand operated and is only for the cross drill and edge drill holes and does not do specialty holes or latch mortising U.S. Pat. No. 4,331,411 from May 25, 1982 by Kessinger et al is a drill system with bits for cross drill and edge drill holes and does not do specialty holes or latch mortising U.S. Pat. No. 3,635,571 from Jan. 18, 1972 by Roberts et at is only for the cross drill and edge drill holes and does not do specialty holes or latch mortising. U.S. Pat. No. 3,338,277 from Aug. 29, 1967 by J. A. Tornoe et al is only for the cross drill and edge drill holes and does not do specialty holes or latch mortising U.S. Pat. No. 3,302,674 from Feb. 7, 1967 by F. J. Russell et al is for only the cross drill hole with the drill guide size being changeable and does not do specialty holes or latch mortising U.S. Pat. No. 3,293,954 from Dec. 27, 1966 by F. J. Russell et at is for only the cross drill and edge drill guide with backsets of 2¾ inch and 5 inch and does not do specialty holes or latch mortising U.S. Pat. No. 3,212,366 from Oct. 19, 1965 by F. J. Russell et al is for only the cross drill and edge drill guide with backsets of 2¾ inch and 5 inch and does not do specialty holes or latch mortising U.S. Pat. No. 3,048,062 from Aug. 7, 1962 by I. C. Bass is for only the cross drill and edge drill guide and has bits attached and does not do specialty holes or latch mortising U.S. Pat. No. 3,021,734 from Feb. 20, 1962 by E. L. Schlage is for only the cross drill and edge drill guide and has bits attached and does not do specialty holes or latch mortising. U.S. Pat. No. 3,008,359 from Nov. 14, 1961 by B. A. Mackey is for only the cross drill and edge drill guide for a pilot drill and does not do specialty holes or latch mortising. U.S. Pat. No. 2,843,167 from Jul. 15, 1958 by E. R. Rushton is for only the cross drill and edge drill guide with backsets of 2⅜ inch and 2¾ inch and 5 inch and does not do specialty holes or latch mortising. U.S. Pat. No. 2,814,219 from Nov. 26, 1957 by W. B. Zern is for the cross drill and edge drill guide with a guide for drilling for the latch screws and does not do specialty holes or latch mortising U.S. Pat. No. 2,679,771 from Jun. 1, 1954 by E. L. Schlage is only an edge drill guide with a cross drill marker and does not do specialty holes or latch mortising U.S. Pat. No. 2,679,174 from May 25, 1954 by E. L. Schlage is only an edge drill guide and a cross drill marker for a pilot drill but one model has an adjustable backset cross drill guide. This jig does not do specialty holes or latch mortising U.S. Pat. No. 2,519,468 from Aug. 22, 1950 by E. A. Hengst is only a pilot drill guide for the cross drill hole and does not do specialty holes or latch mortising U.S. Pat. No. 2,033,072 from Mar. 3, 1936 by F. H. Harp is a door drill jig with an odd design and is very old. U.S. Pat. No. 1,919,900 from Jul. 25, 1933 by E. A. Moller is only for the cross drill and edge drill guide and may not be useable for modern locks. U.S. Pat. No. 4,248,554 from Feb. 3, 1981 by Boucher et al is only for the cross drill and edge drill guide with only 2⅜ inch and 2¾ inch backsets and does not do specialty holes or latch mortising U.S. Pat. No. 7,316,527B2 from Jan. 8, 2008 by Trettin et al is a set of drill guides to cross drill and edge drill holes and is made of plastic with limited life and does not do specialty holes or latch mortising. U.S. Pat. No. 6,398,465B1 from Jun. 4, 2002 by Monge is for only the cross drill and edge drill guide for use with 2⅜ inch and 2¾ inch backset and has removable drill guide and does not do specialty holes or latch mortising U.S. Pat. No. 4,715,125 from Dec. 27, 1987 by Livick is only for the cross drill and edge drill guide and screw holes for latch with adjustable backsets and does not do specialty holes or latch mortising. U.S. Pat. No. 4,130,930 from Dec. 26, 1978 by Webster is only for the cross drill and edge drill guide and does not do specialty holes or latch mortising. 
         [0012]    Other prior art that primarily does only the cross drill and edge drill that no patent was found for but may exist includes an installation jig marketed by Weslock that does 2⅜, 2¾ and 5 inch backset in addition to the edge hole and uses a bit that fastens to the jig in one of two locations for the cross drill with a break through ring on the opposite side of the door and does not do specialty holes or latch mortising. Also not found in the patents is a jig that was marketed by Ilco that they named Accubore. That jig does the cross drill and the edge drill with several different size wood bits and break through rings for the cross drill. The jig has the backset adjustment which is a plate that rotates above and below the one inch edge drill with 2⅜, 2½ and 2¾ inch backsets. That jig also has a sleeve that goes in the 1 inch edge drill guide that is a drill guide for ⅞ inch diameter edge drill hole. The cross drill bits were hand operated but there was an adapter for a drill motor and does not do specialty holes or latch mortising. Another jig that no patent was found that was marketed as WildJig-1 uses a 2⅛ or 1½ inch cross drill and 1 inch edge drill and also has through bolt drilling for some grade 1 locks. The uniqueness of this jig is how it fastens to the door and speed of doing so but does not do latch mortising. 
         [0013]    Jigs for doing mortising for mortise locksets with the use of a router include the following patents however are not designed to do cylindrical locksets with specialty holes as shown in US Pending Patent number US2008/0251154A1 from Oct. 16, 2008 by Gill, U.S. Pat. No. 1,718,324 from Jun. 25, 1929 by F. W. Wappat, U.S. Pat. No. 1,738,227 from Dec. 3, 1929 by R. L. Carter, U.S. Pat. No. 4,235,268 from Nov. 25, 1980 by Savary are mortise templates for doors and jams and U.S. Pat. No. 2,605,791 from Aug. 5, 1952 by W. B. Zern is for router guide system for locks. 
         [0014]    Other lock preparation jigs and mortising jigs date back into 1800&#39;s showing the need and the numerous attempts to devise the perfect jig. Most jigs were for mortise locks but some could be used for cylindrical. None of these jigs would be acceptable for the modern day locks requiring multiple specialty holes and none of these jigs use a router. Here are several patents that show this type of prior art: U.S. Pat. No. 1,210,942 from Jan. 2, 1917 by E. B. Jones, U.S. Pat. No. 992,500 from May 16, 1911 by A. A. Harvie, U.S. Pat.

         [0015]    There are a number of router templates to do various functions of lock preparations but none provide the means to include the specialty holes needed. The following patents are how a router can be used in lock preparation: U.S. Pat. No. 5,573,352 from Nov. 12, 1996 by Matadobra is a router template to cut cross drill holes in face of door, U.S. Pat. No. 1,679,074 from Jul. 31, 1928 by R. L.

No. 5,154,214 from Aug. 13, 1992 by Hagerman is a template for mortising door hardware. 
         [0016]    There are some jigs that are only drill guides for doing various parts of lock preparation, none of which do a total door preparation. U.S. Pat. No. 5,116,170 from May 26, 1992 by Palmer et al is for adding top and bottom holes for through bolt of the brand “Best” locks, U.S. Pat.

         [0017]    Lockset installation jigs that do the cross drill and edge drill and specialty holes but does not do the latch plate mortise would include: U.S. Pat. No. DES. 356,271 from Mar. 15, 1995 by Adamik et al is for cross drill and edge holes and specialty holes—only one side of door with multiple backsets, U.S. Pat. No. 6,193,449B1 from Feb. 27, 2001 by Diaz is a device to drill the cross and edge holes that pre-drill latch screw holes to fasten jig to the door—jig has removable cross drill guide and guide is only on one side of the door. 
         [0018]    There are machines available to do the door lock preparation in a factory setting. Some of these machines will do a total lock preparation while others only do parts of the preparation. Most of the machines are not portable however they show the need for having jigs or equipment to do the door preparation. None of these machines are light weight and universal to do a total lock preparation for a cylindrical type lock in the field. Examples of these machines are seen in patents U.S. Pat. No. 3,319,672 from May 16, 1967 by W. C. Phelps is not portable, U.S. Pat. No. 3,339,601 from Sep. 5, 1967 by C. E. Christman et al is not portable, U.S. Pat. No. 3,280,863 from Oct. 25, 1966 by L. T. Sturgis is not portable, U.S. Pat. No. 2,790,470 from Apr. 30, 1957 by P. R. Graham is a mortising and boring machine, U.S. Pat. No. 2,945,520 from Jul. 19, 1960 by K. W. Grubb is not portable, U.S. Pat. No. 3,263,723 from Aug. 2, 1966 by R. M. Sheffield et al is not portable, U.S. Pat. No. 4,031,931 from Jun. 28, 1977 by Balcombe is portable and U.S. Pat. No. 4,485,857 from Dec. 4, 1984 by Norlie et al does total lock preparation and hinges preparation, not for field use. 
         [0019]    There are jigs available for doing mortising with the use of a router of the latch plate and in some cases the jig will do the strike plate on the door frame. These jigs are designed to do just one part of the lock installation unlike the current embodiment that does the total door lock preparation. Some examples of these jigs would be U.S. Pat. No. 5,762,115 from Jun. 9, 1998 by Shouse is a T-shaped template for latch on 1⅜ inch thick door and 1¾ inch thick door and hinge guide—jig is clamped to door. 
         [0020]    This prior art illustrates the many devices that do only part of the installation and are difficult to use and as such the present invention has been designed as an accurate total door lock installation device. 
       SUMMARY OF THE INVENTION 
       [0021]    The present invention over comes the deficiencies of the other jigs by providing a lock installation system for use on wood, fiberglass and metal doors that is one setup that will totally prepare the door for lock installation. 
         [0022]    The main frame of the device is comprised of end blocks, backset adjustment, spacer plate, main base plate, main support arm, secondary support arm and the pressure support arm, provide for a router template center cut out guide in the main base plate to cut the mortise for 1⅛ inch wide latch mortise and also allows for fast changing of the backset for 2⅜ inch or 2¾ inch on each end of the main frame assembly. The main frame allows for centering or offset drilling of the edge hole and latch mortise. There are door drill plates fastened to the main support arm and secondary support arm of the main frame that act as a template of drill guides for the various different size holes and location as to brand of lock. 
         [0023]    The device is held on the door by pressure from a pressure bolt located in the pressure support arm of the main frame to one of the door drill plates and with the door being sandwiched between the other door drill plate which causes a clamping action on the door and thus holding the device on the door. The device forms a U-shape around the door. 
         [0024]    The door drill plates come in sets of two for the many different brands of locks with the different configurations of holes. 
         [0025]    There are two attachments that are held on the main base plate by a special bolt in each of the two end blocks and the first attachment is the edge drill setup. There are four different models with all having drill guides to pre-drill the latch screws. The only difference between the models is the diameter of the hole for the latch assembly. The first model has ¼ inch hole as a pilot hole for a hole saw, ⅞ inch hole is for residential locksets, 1 inch hole is for most locksets and as a guide to align the device properly for re-drilling or adding extra holes to an existing lockset preparation and the model with the 1⅛ inch hole is for specialty locks. The second attachment is the secondary base plate that is a router template center cut out guide for the narrow one inch wide latch face plate. 
         [0026]    It is an object of the present invention to provide a lock installation system to be simple and fast to install and remove from door. 
         [0027]    It is an object of the present invention to provide a lock installation system to accommodate lock installation requirements of 2⅜ inch backset and 2¾ inch backset. 
         [0028]    It is an object of the present invention to provide a lock installation system to accommodate doors 1¼ inch thick to 2⅜ inch thick. 
         [0029]    It is an object of the present invention to provide a lock installation system to do both off center edge and center of edge of door drilling and mortising. 
         [0030]    It is an object of the present invention to provide a lock installation system to do both mortising on door edge for 1 inch wide and 1⅛ inch wide latch face plates. 
         [0031]    It is an object of the present invention to provide a lock installation system to pre-drill the latch screw holes. 
         [0032]    It is an object of the present invention to provide a lock installation system to protect wood doors from splitting when drilling the door edge by means of sandwiching the door between the door drill plates. 
         [0033]    It is an object of the present invention to provide a lock installation system to drill or re-drill the main cross hole in the door faces. 
         [0034]    It is an object of the present invention to provide a lock installation system to drill the specialty holes for lever locks and access control locks. 
         [0035]    It is an object of the present invention to provide a lock installation system to do multi-door lock preparations of door 1⅜ inch thick or 1¾ inch thick with minimal setup for the same type of lock preparation. 
         [0036]    The primary purpose of the smaller embodiment is to provide a means to alter an existing preparation or add holes to an existing preparation where door edge latch mortising is not required.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0071]    The present invention provides a tubular style lock installation device having body members of two end blocks  100  as a means that each provides for the mounting of the backset adjustment  200  with the use of threaded hole  101  for a shoulder bolt  102  on side B of end block  100 , side A of end block  100  having a hole  103  for body member of support shaft bolt  604  that extends to side E for support of three body member parts known as main support arm  600  also secondary support arm  700  and the pressure support arm  800 . Side C of end block  100  has a threaded hole  104  for thumb turn  106  to lock support shaft bolt  604  from moving during use. Side C of end block  100  also has a second threaded hole  107  with Heli-coil  108  for longer life that extends to side D of end block  100  for knob  109  that has a threaded shaft with a point that is a means to lock secondary base plate  500  or edge drill setup series  900  in place at a designated location to drill and mortise door edge on center or off center. Side A of end block  100  has a threaded hole  110  that intersects with threaded hole  107  on side C of block  100  that extends to side D of end block  100 . The purpose of hole  110  is for use of a nylon tipped set screw  112  as a means for a friction break for knob  109  that has a threaded shaft with a point. Side D of end block  100  also has two other threaded holes  116  for a means of mounting body member main base plate  400  and spacer plate  300 . Side B of end block  100  in addition to the threaded hole  101  for a means to mount the backset adjustment  200  also has a hole  113  for a pin  114  and spring  115  that is a means to creates a backset rotation limit to prevent the free spinning of the backset adjustment  200 . There is a small hole  203  in each backset adjustment  200  as a means to depress the rotation limit pin  114  to allow rotation of backset adjustment  200  for the needed setting of 2⅜ inch backset or 2¾ inch backset. The location of the backset adjustment hole  101  on side B of end block  100  and the location of support shaft bolt hole  103  on sides A and E are necessary for the accuracy for backset. The preferred material for the end block  100  is aluminum because of it is wear resistance and will not rust and also is light in weight. The end block  100  must be of size to allow the main support arm  600  and the secondary support arm  700  to close for a 1¼ inch thick door. The door thickness for this embodiment is 1¼ inch to 2⅜ inch but also may be increased for thicker doors by changing the two support shaft bolts  604  to longer support shaft bolts. For thinner than 1¼ inch thick door would require thicker door drill plate series  1000  or a shim between door drill plate series  1000  and main support arm  600  and secondary support arm  700 . 
         [0072]    The two end blocks  100  slide freely on the two support shaft bolts  604  with the main base plate  400  and two spacer plates  300  and with attachment secondary base plate  500  if installed or edge drill setup series  900  if installed. The two end blocks  100  can be locked to the two support shaft bolts  604  with thumb turn  106  on each end block  100  as a means of centering the main base plate  400  on the edge of the door or to do off set drilling on the edge of the door. There may be centering clips  605  installed into holes  606  in the support shaft bolts  604  on each side of each end block  100  as a means for a dedicated door edge drilling setup series  900 . 
         [0073]    The backset adjustment  200  is a plate two inches wide to hit against the door edge as a means of setting the backset of 2⅜ inch or 2¾ inch from the latch center on edge of the door to the center of the main hole in the door face. The backset adjustment  200  should have cut outs on each side as a means to identify that it is the side of the backset adjustment. The width of two inches is to span across any cut out or damage and to aid in centering on the door. The off set hole  201  in backset adjustment  200  is what determines the backset of 2⅜ inch or 2¾ inch and there for must be ⅜ inch difference from one face to the other. Other cosmetic designs may be used as long as the above specifications are met. There is a small hole  203  in each backset adjustment  200  as a means to depress the rotation limit pin  114  to allow rotation of backset adjustment  200  for the needed setting of 2⅜ inch backset or 2¾ inch backset. There is a step drilled hole in two locations  203  on the backside of backset adjustment  200  for the rotation limit pin  114  as a means to prevent free rotation of backset adjustment  200  but to allow some rotation on each of the two settings for use on beveled doors. 
         [0074]    The spacer plate  300  is a means used to create a void between side D of the end blocks  100  and main base plate  400  to allow the ends of secondary base plate  500  with centering hole  501  or the ends of the edge drill setup series  900  with centering hole  905  to enter that void and to be centered and secured to the main base plate  400  by knob  109  that has a threaded shaft that threads through the end block  100  side C hole  107  and comes out end block  100  hole  107  side D and is pointed on the end. The spacer plate  300  is not the same size of end block  100  side D and has two holes  116  for the two screws  117  that attach the main base plate  400  to the end blocks  100  side D. 
         [0075]    The main base plate  400  is a guide with center cut out hole  402  for a router with ½ inch diameter guide attachment and ¼ inch router bit as a means to cut the mortise cut out for a latch plate of 1⅛ inch wide by 2¼ inch long. The main base plate  400  must be adequate width and thickness to safely support the router but narrow on the ends that connect to the end blocks  100  to allow both the main support arm  600  and the secondary support arm  700  to pass to accommodate for door thickness. The main base plate  400  has two holes  401  on each end as a means to fasten the spacer plates  300  and end blocks  100 . The main base plate  400  may also have 4 holes  405  with harden drill guide inserts  403  as a means for drilling mounting holes for installing latch mounting plates in steel doors. The center cut out guide  402  in the center of main base plate  400  must be large enough to compensate for the size of the router guide to cut 1⅛ inch wide by 2¼ inch long hole. The depth of the cut is determined by the latch thickness and is set on the router. The main base plate  400  is also used as a base as a means to support the secondary base plate  500  and edge drill setup series  900 .

       OPERATION INSTRUCTIONS OF THE PREFERRED EMBODIMENT 
       [0101]    The operation of the embodiment:
       1. Determine which set of door drill plates series  1000  are needed for hardware being installed and then install one door drill plate series  1000  onto main support arm  600  and the other door drill plate series  1000  onto the secondary support arm  700 .   2. Determine from hardware to be installed what backset adjustment is needed and set the backset adjustment  200  by depressing the rotation limit pin  203  with a small wire and rotate backset adjustment  200  to the needed setting of 2⅜ inch backset or 2¾ inch backset. The backset adjustment  200  will self adjust for beveled or square edge door when the embodiment is installed on the door. The backset adjustment  200  is on both the top and bottom of the embodiment.   3. Determine the thickness of the door that the preferred embodiment is to be installed on.   4. Determine if the thickness of the door is the standard 1⅜ inch thick or 1¾ inch thick and if the latch assembly is to be installed in the center of the edge of the door or offset from the center of the door.   5. If the door is of standard thickness and the door edge is to be center cut and the preferred embodiment needs to be adjusted for a different door thickness than it is set for then remove centering clips  605  from the support shaft bolts  604  and loosen thumb turn  106  on each of the end blocks  100 . Then slide the end blocks  100  on support shaft bolts  604  to the appropriate location for the door thickness and install centering clips  605  in support shaft bolt  604  in holes  606  on each side of each end block  100 , then retighten thumb turn  106  in each end block  100  to prevent any additional movement.   6. If the door is of non-standard thickness or offset drilling is to be done then remove the centering clips  605  from each support shaft bolt  604 . Loosen thumb turn  106  on each end block  100 . Using a carpenter′ square put a vertical line on the edge of the door in what will be the center of the latch assembly. Install the preferred embodiment on the door and center the two backset adjustments  200  to the vertical line drawn on the door edge. Lock the two thumb turns  106  that lock each end block  100  to support shaft bolt  604 .   7. To install and clamp the preferred embodiment onto the door if this is a complete new installation, then:
           a. A small pencil mark needs to be put on the edge of the door where the top backset adjustment  200  will be. The formula to make that mark is to measure from the outside of one backset adjustment  200  to the outside of the other backset adjustment  200  and divide by 2. Take the answer and measure from where the latch hole center is to be then measure up on the door edge and make a small horizontal mark.   b. With all adjustments of backset and proper plates premade, install the preferred embodiment on the door with aligning the top backset adjustment with the horizontal mark on the door. Tighten pressure bolt  806  with knob  808  to clamp the preferred embodiment to the door as a sandwiching of the door with the door drill plates series  1000 .   c. If offset drilling or non-standard edge drilling is being done where centering clips  605  are not used then the backset adjustments  200  must be centered to the vertical pencil line on the door as talked about in number 6 and then the end blocks  100  must be locked to the support shaft bolt  604  by tightening thumb turn  106 .   
           8. If the preferred embodiment is being installed onto an existing lock preparation then install edge drill setup  900 - 3  with the 1 inch hole  903  and use alignment tool  909  in the drill edge setup  900 - 3  to enter the existing edge drill hole in the door. If the existing edge drill hole in the door is not center of the edge of the door or this is a non-standard door then remove centering clips  605  and loosen thumb turn  106  to allow the edge drilling assembly to self center to the existing edge hole and then retighten thumb turn  106  that locks end blocks  100  to support shaft bolts  604  on each end of the preferred embodiment.   9. To install the edge drill setup series  900  or the secondary base plate  500  loosen knob  109  on each end block  100  sufficient to install or remove edge drill setup series  900  or the secondary base plate  500 . When installing use the small mark on each end of the edge drill setup series  900  or the secondary base plate  500  to assist in determining the proper location of the hole for knob  109  with point to locate and enter hole  905  or hole  501 . Slowly tighten knob  109  as you wiggle the attachment being installed and you will feel when it begins to enter the hole  905  or hole  501 , do not fully tighten. Now do the other end of the attachment being installed in the same fashion but when you have knob  109  centered in the hole you may tighten that knob  109  and then retighten the other knob  109 .   10. The holes maybe drilled in what ever order that are most convenient. Hole saws and drills in steel should be run at low speed to prevent overheating. Hole saws when drilling wood perform best when run at a high speed. When drilling the door face, first drill part way through from one side and then go to the matching hole on the other side of the door and drill to complete the hole. Drill the 3 holes on the door edge that include the 2 predrilled latch plate screw holes  906 .   11. Remove the edge drill setup series  900 .   12. Install the secondary base plate  500  if needed.   13. Use a router with the appropriate router guide and router bit, set at the appropriate depth to cut the mortise for the latch plate. Install the router in the off position onto the main base plate  400  or the secondary base plate  500  with the bit of the router being in the edge drill hole. Turn on router and cut the mortise then turn router off and it allow it to stop running before removing the router from the preferred embodiment to prevent damage to the preferred embodiment. There are two ways to set the router for depth of cut to cut the mortise cut out with one being with the use of the depth measuring part of slide calipers. Put the latch plate on the main base plate  400  or on the secondary base plate  500  if it is being used, then measure from the latch plate to the uncut door and transfer that measurement to the tip of the router bit and the base of the router. The other method for setting the router for depth of cut is to use a setup gauge that has three cutouts: one for residential latch 2⅜ inch backset, one for residential latch 2¾ inch backset and one for commercial latch for 2¾ inch backset. Select the right cutout and adjust the router bit to bottom out on the cutout when the ends of the gauge are against the router base.   14. Remove the preferred embodiment from the door.   15. In some situations extra clamping from an external clamp that is not a part of this preferred embodiment will be needed to keep the preferred embodiment from moving on door.   16. It is recommended on most installations that a paper towel be used between the door drill plate series  1000  and the door to protect the door from being marred.   17. To square the corners of the latch plate mortise cut out in wood, the use of a corner chisel works very well but is not a part of this preferred embodiment.   18. If a router is used to cut a door edge that is made of steel or aluminum then it is recommended to use a double flute carbide router bit and grease the door edge in the area that is being cut to help the bit from getting clogged. Great care must be taken not to break the bit and extra safety precautions should be taken.   19. A full face safety shield should be used for eye and face protection and steel toed shoes incase the preferred embodiment is dropped. No loose clothing near the drill bits should be used.

If the door is of non-standard thickness or offset drilling is to be done then remove the centering clips  605  from each support shaft bolt  604 . Loosen thumb turn  106  on each end block MJ 10 . Using a carpenter&#39; square put a vertical line on the edge of the door in what will be the center of the latch assembly. Install preferred embodiment on the door and center the two backset adjustments  200  to the vertical line drawn on the door edge. Lock the two thumb turns  106  that lock each end block MJ 10  to support shaft bolt  604 .   7. To install and clamp the preferred embodiment onto the door if this is a complete new installation, then:
           a. A small pencil mark needs to be put on the edge of the door where the top backset adjustment  200  will be. The formula to make that mark is to measure from the outside of one backset adjustment  200  to the outside of the other backset adjustment  200  and divide by 2. Take the answer and measure from where the latch hole center is to be up on the edge door and make a small horizontal mark.   b. With all adjustments of backset and proper plates premade, install the preferred embodiment on the door with aligning the top backset adjustment with the horizontal mark on the door. Tighten pressure bolt  806  with knob  808  to clamp the preferred embodiment to the door as a sandwiching of the door with the door drill plate series  1000 .   c. If offset drilling or non-standard edge drilling is being done where centering clips  605  are not used then the backset adjustments  200  must be centered to the vertical pencil line on the door edge as talked about in number 6 and then the end blocks MJ 10  must be locked to the support shaft bolt  604  by tightening thumb turn  106 .   
           8. If the preferred embodiment is being installed onto an existing lock preparation with edge drill plate MJ 20 - 3  with the 1 inch hole MJ 23  installed use alignment tool  909  in the edge drill plate hole MJ 23  to enter the existing edge hole in the edge of the door. If the existing edge drill hole is not center of the edge of the door or this is a non-standard door then remove centering clips  605  and loosen thumb turn  106  on each end block to allow the edge drilling assembly to self center to the existing edge hole and then retighten thumb turn  106  on each end block MJ 10  that locks end blocks MJ 10  to support shaft bolts  604 .   9. The holes maybe drilled in what ever order that are most convenient. Hole saws and drills in steel should be run at low speed to prevent overheating. Hole saws when drilling wood perform best when run at a high speed. When drilling the door face, first drill part way through from one side and then go to the matching hole on the other side of the door and drill to complete the hole. Drill the 3 holes on the door edge that include the 2 predrilled latch plate screw holes MJ 25 .   10. Remove the preferred embodiment from the door.   11. In some situations extra clamping from an external clamp that is not a part of this preferred embodiment will be needed to keep preferred embodiment from moving on the door.   12. It is recommended on most installations that a paper towel be used between the door drill plate series  1000  and the door to protect the door from being marred.   13. A full face safety shield should be used for eye and face protection and steel toed shoes incase the preferred embodiment is dropped. No loose clothing near the drill bits should be used.
