     BACKGROUND OF THE INVENTION  
      Conventional mortise cylinder and rim cylinder locks are ubiquitous in commercial and retail environments. Each conventional mortise cylinder lock and rim cylinder lock includes a cylinder made of metal, typically brass that fits into a circular opening in a door lock. The cylinder includes a key opening on an outer face. The key opening leads to a smaller diameter cylinder, also known as a plug, that includes a plural pin tumbler. The plug is typically offset from the central axis of the cylinder. A cam which is typically a cylindrical component having an appendage extending from its periphery for a mortise cylinder lock or a straight cam, which is also known as a connecting bar or spindle, for a rim cylinder lock attaches at an end of the plug opposite the key opening. The cam, which can be many different shapes dependant upon the manufacturer of the lock, cooperates with the lock of the door. With the proper key inserted into the key opening, the tumblers align allowing the key to turn resulting in the cam turning and operating the lock.

     SUMMARY OF THE INVENTION  
      An automated assembly for operating a lock in a door includes a housing, a lock adapter assembly, a powered drive mechanism, and a conversion cam. The housing includes an opening dimensioned to receive an associated lock cylinder that is typically removed from the lock in the door to which the assembly will mount. The lock adapter assembly includes a portion extending away from the housing and shaped to be received in an opening in an associated door lock that was once occupied by the associated lock cylinder. The lock adapter assembly includes a mounting member for mounting an associated cam that corresponds to the associated lock cylinder. The conversion cam can mount to the associated lock cylinder and cooperate with the lock adapter assembly and/or the powered drive mechanism such that movement of the conversion cam results in the mounting member moving the associated cam to operate the associated door lock.  
      A method for converting a manual cylinder lock, e.g. a mortise cylinder or a rim cylinder, to an automated lock includes the following steps: removing a lock cylinder from a door lock so that a cylindrical opening remains in the door; removing a cam that cooperated with the door lock from the lock cylinder; attaching the cam from the lock cylinder to a lock adapter assembly of an automated lock assembly; and mounting the automated lock assembly to the door such that at least a portion of the lock adapter assembly fits into the cylindrical opening of the door.  
      The automated assembly can also cooperate with a deadbolt assembly to provide an automated lock. In one embodiment the assembly includes a housing that is adaptable between a right-hand and left-hand configuration. A gear train that is disposed in the housing is also easily configurable to drive a rotary deadbolt for either a left-hand or right-hand configuration. The housing can also be adaptable to accommodate a linear deadbolt assembly through either a top or bottom of the housing.  
     DETAILED DESCRIPTION OF THE INVENTION  
      With reference to  FIG. 1 , an automated lock assembly A includes a housing  10  that can attach to a door and/or door lock (not shown). The door lock can already include a mortise cylinder or a rim cylinder, both referred to as an original lock cylinder B, that is operatively connected to a lock of the door (not shown). With reference to  FIG. 2 , when using the automated lock assembly A, the original lock cylinder B that is mounted to the door is removed prior to mounting the housing  10  to the door. The housing  10  has a plurality of connected walls including a first wall  12  positioned adjacent the door when the assembly A is mounted to the door and a second wall  14  that is spaced from and parallel to the first wall. The first wall  12  includes a first opening  16  that receives a lock adapter assembly, either a mortise cylinder adapter assembly C or a rim cylinder adapter assembly D. The second wall  14  includes a second opening  18  that is offset from the first opening  16  that receives the original lock cylinder B, which has been removed from the door.  
      The automated lock assembly A can lock and/or unlock the door lock once operated by the original lock assembly B either automatically, e.g. remotely, using a key of the original lock cylinder B, or using other sensor devices. Each original lock cylinder B, both the mortise cylinder and the rim cylinder, includes a cylindrical housing  20  that can include two grooves  28  (only one shown in  FIG. 2 ) that cooperate with pins in the door lock so that the cylinder cannot be unscrewed from the door lock without first removing the pins. An original cam, which can be a cam  22  comprising cylindrical component having an appendage for the mortise cylinder or a straight cam  24  for the rim cylinder, mounts to the cylindrical housing  20  of the original lock cylinder. The original cam  22 ,  24  cooperates with the lock found in the door to which the automated lock assembly A will mount. Before inserting the original cylindrical housing  20  into the second opening  18 , the original cam  22 ,  24  is removed and a conversion cam  26  using fasteners  32  ( FIG. 3 ) or a clip (not shown) is mounted to the original cylinder  20 . The original cam  22  for the original mortise cylinder attaches to the mortise cylinder adapter C and the original cam  24  for the rim cylinder attaches to the rim cylinder adapter D. The cams can mount to the cylinders in other conventional manners.  
      The original cylinder B mounts inside the second opening  18  by screwing the original cylinder into the opening. In such a configuration the original cylinder B includes threads and the housing  10  includes corresponding threads. Alternatively, the original cylinder B mounts in the housing  10  by using rear mounting screws; however, it is understood that the original cylinder B can mount inside the housing in other conventional manners. With reference to  FIG. 3 , a spacer ring  34  can be provided sandwiched between the cylindrical housing  20  and the second wall  14  to provide for proper spacing and alignment for the cylindrical housing. A removable lid  36  attaches to the rear of the housing  10  using fasteners  38 . Locking pins  42  extend from the lid  36  into the housing and are received in the grooves  28  of the cylindrical housing  20  and in grooves  29  of the housing  10  (only one shown in  FIG. 3 ) so that the cylindrical housing cannot be unscrewed without removing the lid  36 .  
      With reference back to  FIG. 2 , the lock adapter assemblies C and D operate the lock in the door. Both adapter assemblies C and D fit, only one at a time, into both the first opening  16  of the housing  10  and the opening in the door lock where the original cylinder B was located. Both cylinder adapters include a similar gear train to operate the lock of the door, which allows for easier manufacture of the assembly.  
      With reference to  FIG. 4 , the mortise lock adapter assembly C includes an elongated driven gear  52  mounted to a gear mounting chassis  54 . The gear mounting chassis  54  includes a plate  64  having a pair of parallel struts  66  extending normally from the plate. A brace  68  interconnects the struts  66  at an end opposite the plate. The gear mounting chassis  54  also includes two alignment grooves  70  that are similar to the alignment grooves  28  on the original cylinder  20 .  
      The driven gear  52  mounts between the struts  66  to the brace  68  at one end and to a gear mounting plate  56  at an opposite end. More specifically, the brace  68  includes an opening  72  that receives an axle  74  of the driven gear  52  and the gear mounting plate  56  also includes an aligned opening  76  that receives the axle  74 . The driven gear  52  is elongated, which allows for the lock adapter assembly to be easily adjusted, which will be described in more detail below.  
      The gear mounting plate  56  attaches to the gear mounting chassis  54  using fasteners  80  and includes a circular depression  78  that receives a cam mounting member  58 . The circular depression  78  is offset from the central axis of the gear mounting plate  56  and the mortise lock adapter assembly C. This is similar to the offset of the plug in a conventional lock cylinder. A first gear opening  82  is located in the center of the circular depression  78 . An output drive gear  84 , which is mounted to the cam mounting member  58 , protrudes through the gear opening  82  so that the output drive gear  84  engages the driven gear  52 . The gear mounting plate  56  includes a second gear opening  86 , which is located directly above the first gear opening  82 , perpendicular to the central axis. An auxiliary gear  88  mounts in the opening  86  and also engages the driven gear  52 . The gear mounting plate also includes two grooves  92  that align with the two grooves  70  on the gear mounting chassis  54 .  
      A cylindrical housing  62  attaches to the gear mounting plate  56  and the plate  64  of the gear mounting chassis  54 . The housing  62  receives the cam mounting member  58 . The housing  62  includes a cam opening  94  that is offset from the central axis of the base  62  and the assembly C and aligned with the circular depression  78  of the gear mounting plate  56 . The cam mounting member  58  includes a cam mount  96  on an end of the cam mounting member  58  opposite from and operatively connected to the output drive gear  84 . The original cam  22 , which was removed from the original mortise cylinder B, attaches to the cam mount  96  and protrudes through the cam opening  94  of the housing  62 . Movement of the driven gear  52  results in movement of the original cam  22  to operate the lock of the door to which the automated assembly mounts.  
      The housing  62  also includes alignment grooves  98  (only one visible in  FIG. 4 ) that align with the grooves  70  and  92 . The alignment grooves  70 ,  92  and  98  align with and receive semicyindrical sidewall protrusions  100  ( FIG. 3 ) in the housing  10 .  
      The rim cylinder adapter assembly D depicted in  FIG. 5  includes many of the same components as the mortise cylinder adapter assembly C depicted in  FIG. 4 . Many of the reference numerals used to describe the mortise cylinder adapter assembly C will also be used to describe the rim cylinder adapter assembly D. This is simply for the sake of brevity and ease of understanding  FIG. 5 . It is to be understood that other assemblies and components can be used and the embodiments disclosed are not to be limited to only those assemblies and components described.  
      With reference to  FIG. 5 , the rim cylinder adapter includes the driven gear  52  mounted to the gear mounting chassis  54 . The driven gear  52  mounts between the struts  66  of the chassis  54  and drives an output drive gear  84  that extends through an opening  82  in a gear mounting plate  106 . The gear mounting plate  106  for the rim cylinder adapter can include a cylindrical rim  108  extending from the periphery of the plate  106 . The rim  108  is similar to a rim found on a conventional rim cylinder. The output drive gear  84 , however, attaches to a straight cam or spindle mounting member  60 . The original straight cam  24  mounts to an end of the cam mounting member  60  using a clip as know in the art. The original cam  24  mounts opposite the output drive gear  84  and extends through an opening  94  in a housing  102  that receives the cam mounting member. The housing  102  is similarly shaped to the housing  62  of the mortise cylinder adapter assembly; however, the housing  102  for the rim cylinder adapter assembly includes grooves  98  that do not run the length of the housing. The housing  102  can take other configurations than cylindrical.  
      Since the original cam  22  that attaches to the mortise cylinder adapter assembly C and the original cam  24  that attaches to the rim cylinder adapter cylinder D engages the lock of the door, each lock assembly C and D protrudes into the door. The depth that each assembly C and D protrudes from and into the housing  10 , thus the portion that can protrude into the opening of the door lock, can be adjusted to accommodate doors of different thickness. With reference to  FIG. 6 , the elongated driven gear  52  can engage a transmission that will be described in more detail below anywhere along the length of the driven gear. Accordingly, the additional depth that each assembly C and D can protrude is equal to the dimension “x” depicted in  FIG. 6 .  FIG. 6  depicts the mortise cylinder adapter assembly C; however, the transmission can operate the rim cylinder adapter assembly also. Furthermore, an elongated member, for example a rod or the like can be used instead of the elongated driven gear  52  to provide an adjustable assembly. The rod can cooperate with a transmission similar to that described below. Such a configuration may obviate the need for mounting struts  66 .  
      Additionally, each adapter assembly C and D can be rotated 180 degrees to reposition the cam mount  96  in the mortise cylinder adapter assembly C or the cam mounting member  60  in the rim cylinder adapter assembly D. In some doors the key cylinder is offset above the central axis of the lock cylinder; however, to automate these door locks it may be impractical to rotate the entire housing  10  of the automated lock assembly A so that it is mostly above the adapter assembly C or D. Since the driven gear  52  of the mortise cylinder adapter assembly C and the rim cylinder adapter assembly D is located on the central axis of the assembly, the assembly can be rotated 180 degrees and inserted into the first opening  16  of the housing  10  without affecting the alignment of the driven gear  52 , while changing the location of the cam mount  96  or the cam mounting member  60  so that it can work with this type of door lock. The alignment grooves  70 ,  92  and  98  still align with the grooves  100  in the housing  10  with the assembly rotated 180 degrees.  
      The driven gear  52  can be driven automatically. With reference to  FIGS. 3 and 6 , a motor  110  drives the driven gear  52  through a transmission made up of a plurality of gears. Alternatively, the transmission can comprise belts, pulleys and the like. In the embodiment depicted, the transmission is a gear reduction transmission; however, other conventional transmissions can be used. Also, the driven gear  52  can be driven automatically by a solenoid or similar device. In the embodiment depicted, the motor  110  drives a pinion  112  that drives a beveled gear  114  having a second pinion  116  attached and concentric thereto. The second pinion  116  drives a first intermediate gear  118  that has a third pinion  120  attached and concentric thereto. The third pinion  120  drives a second intermediate gear  122  that also has a fourth pinion  124  attached and concentric thereto. The fourth pinion  124  drives a third intermediate gear  126  that has a fifth pinion  128  attached and concentric thereto. The fifth pinion  128  engages a fourth intermediate gear  130  which engages the driven gear  52 .  
      The motor  110  is driven by a power source, which can be an internal source such as batteries, an external source such as from an AC power source or a renewable source such as solar cells. As seen in  FIG. 3 , batteries  132 , which in the depicted embodiment are rechargeable batteries, are disposed inside the housing  10  to provide a power source for the motor  110 . A removable lower door  134  attaches to the housing  10  using fasteners  136  to provide access to the batteries  132 . A solar cell  142  mounts to a lower portion of the front of the housing  10  to provide energy to the motor  110  and/or the batteries  132  for recharging. The solar cell can be a flexible thin film cell of the type known in the art. An internal power supply allows the assembly A to be easily mounted to the door lock without having to provide electrical wiring to the assembly. As compared to known devices, not having to provide an electrical connection provides significant cost savings on installation of the assembly. Many times the assembly A is mounted where there is a light source, e.g. outside, and therefore the solar cell  142  can be used to separately power the motor  110  without using the batteries and the solar cell can also recharge the batteries. Accordingly, the life of the power supply can be relatively long, for example on the order of 10 years.  
      The motor can also communicate with a circuit board  144  to which sensors can mount to receive a signal that determines when to drive the motor. For example, the sensors can be RF sensors that can communicate with an RF transmitter. IR sensors and other conventional sensors can also be used. This would allow the lock on the door to be locked and unlocked remotely using a key fob or similar device. The circuit board  144  can also communicate with other conventional electronic equipment, e.g. a hard wired unit, to control the power delivered to the motor. The circuit board  144  mounts behind the solar cell  142  so that the sensors on the circuit board  144  can receive a signal.  
      In addition to being remotely activated, the driven gear  52  can be rotated, and thus the lock of the door can be activated using a key that operates the original lock cylinder B. With reference back to  FIG. 3 , a circuit board  140  mounts inside the housing  10  near the second opening  18 . In one embodiment, a Hall effect sensor mounts to the circuit board  140  and a magnet  142  mounts to the conversion cam  26 . The circuit board  140  communicates with the power source  132 . Rotation of the key in the original lock cylinder B turns the conversion cam  26 . The magnet  142  on the conversion cam  26  activates the Hall effect sensor to deliver a signal to the power source  132  to drive the motor  110  to lock or unlock the door lock. Other known position sensors are also contemplated to provide a signal to the power source  132 .  
      The driven gear  52  can also be rotated manually when the key in the original lock cylinder is rotated. The conversion cam  26  can include teeth that engage a conversion gear  146  that is mounted to an upper gear mounting plate  148 . The circuit board  140  also mounts to the gear mounting plate  148  using conventional fasteners  150 . As seen in  FIG. 6 , the conversion gear  146  engages the driven gear  52 . Accordingly, rotation of the conversion cam  26  results in rotation of the conversion gear  146  which results in rotation of the driven gear  52 .  
      The sensor on the circuit board  144  can also receive a remote signal from a handle assembly  152  ( FIG. 7 ) that can mount to the front of the automated assembly A. The handle assembly  152  includes a handle  154  that mounts to an escutcheon  156 . A spindle  158  connects to the handle  154  and extends away from a side of the escutcheon  156  opposite the handle. The spindle  158  is matingly received in a corresponding opening  162  of a cam plug  164 . A magnet  166  attaches to the cam plug  164  and rotation of the handle results in rotation of the cam plug. The magnet  166  operates a Hall effect sensor mounted to a circuit board  163 , similar to the one described above, to deliver a signal to the circuit board  144 . Other sensors can also be used. The cam plug  164  and sensor components mount inside a protective housing  165  that mounts to the assembly A. The escutcheon  156  and housing  165  mount to the assembly housing  10 . To mount the handle assembly  152  to the housing  10 , a front plate  168  ( FIG. 3 ) which has similar dimensions to the escutcheon  156  can be removed from the housing. The handle assembly  152  provides yet another wireless actuator for the automated assembly A. Also, the handle assembly  152  can mount elsewhere, for example to a nearby wall. The handle assembly  152  can also be hardwired to the circuit board  144 . Since the handle assembly  152  includes a rotating cam  164 , two or more Hall effect sensors can be positioned on the circuit board  163  to provide different signals, for example a lock or unlock signal determined by the rotational position of the magnet  166 .  
      With reference to  FIG. 8 , the automated lock assembly A described above can cooperate with a rotary deadbolt assembly E to provide a deadbolt lock assembly. The rotary deadbolt assembly E includes a housing  210  having a plurality of connected walls including a first wall  212  that will abut the first wall  12  of the housing  10  of the automated lock assembly A when the two assemblies are attached to one another. A gear mounting chassis  214 , which can be similar in configuration to the gear mounting chassis  54  described above, mounts to a cylindrical boss  216  using fasteners  215 . The gear mounting chassis  214  and the cylindrical boss  216  align with the first opening  16  in the first wall  12  of the housing  10  of the automated lock assembly A when the automated lock assembly A and the rotary deadbolt assembly E are attached to one another. The housing  210  also includes a second wall or rear wall  218  that is spaced from and parallel to the first wall  212 .  
      As more clearly seen in  FIG. 9 , a removable rear panel  222  selectively attaches to the housing  210 . The removable rear panel  222  can be removed from the housing to provide access to internal components of the rotary deadbolt assembly E, which will be described in more detail below. The removable rear panel  222  includes a plurality of openings  224  that align with openings  226  in the housing to receive fasteners  228  to attach the removable rear panel  222  to the housing  210 . Even though fasteners are shown to attach the removable rear panel  222  to the housing  210 , the rear panel  222  can attach to the housing via a resilient snap fit or in any conventional manner. The removable rear panel  222  includes a pair of appendages  232  that extend from opposite lateral edges of the rear panel substantially normal to an exposed rear surface of the rear panel.  
      The housing  210  also includes a first side wall  234  and a second side wall  236  connecting the front wall  212  to the rear wall  218 . Each side wall is similarly shaped, and therefore for the sake of brevity, only the first side wall  234  will be described in detail. Each side wall  234  and  236  includes a cut-out  238  extending from the edge of the first side wall that abuts the removable rear panel  222  toward the front wall  212 . Each side wall  234  also includes a recessed surface  242  adjacent the cut-out  238 . Similar to the cut-out  238 , the recessed surface  242  begins at an edge of the first side wall  234  that is adjacent the rear panel  222  and extends towards the front wall  212 . In the embodiment depicted, the recessed surface  242  is adjacent an upper end of the cut-out  238 . An opening  240  is provided in each recessed surface  242 . When the removable rear panel  222  mounts to the housing  210 , the appendages  232  cover the recessed surface  242  such that the appendage  232  is flush with the remainder of the corresponding side wall, either  234  or  236 . Side wall covers  244  (only one shown) are provided to selectively cover the cut-out  238  in either side wall  234  or  236 . In the rotary deadbolt assembly depicted, typically only one side wall cover  244  is used so that one cut-out  238 , either a left-hand or right-hand cut-out, is not covered.  
      The housing  210  also includes a top wall  248  ( FIG. 17 ) that interconnects and is normal to each of the front wall  212 , the rear wall  218 , and the side walls  234 ,  236 . The top wall  248  defines a top cut-out  252  that extends into the top wall from an edge of a top wall adjacent the rear panel  222 . A top cover member  254  is provided to cover the top cut-out  252 . The top cover member  254  includes an opening  256  that receives a fastener  258  to allow the top cover member  254  to attach to the housing  210  and the housing  10  of the automated lock assembly A. Accordingly, the top cover member  254  is selectively removable from the housing  210 , which will be described in more detail below.  
      With reference to both  FIGS. 8 and 9  mounting screws  262  fit into openings  264  in the rotary deadbolt assembly housing  210  which are received in openings  266  in the automated lock assembly housing  10 . Accordingly, the rotary deadbolt assembly housing  210  can attach to the automated lock assembly housing  110 ; however, in alternative embodiments one housing can be provided to house the components of both the rotary deadbolt assembly E and the automated lock assembly A. Longer fasteners can be provided where the fastener extends through the rear wall  218  and the front wall  212 , and shorter fasteners can be provided where the fastener only extends through the front wall  212 .  
      A rotary deadbolt  270  and a gear train for the rotary deadbolt are disposed in the housing  210 . The gear train includes a worm gear assembly, which inhibits one from prying the deadbolt to unlock the door. An axially elongated gear  272 , similar to the axially elongated gear for the automated assembly A, has a worm  274  extending concentrically from the gear. As more clearly seen in  FIGS. 10-13 , the worm  274  engages a corresponding worm gear  276 . A first pinion  278  is concentric with and connected to the worm gear  276  and a second pinion  282  is concentric with and attached on an opposite side of the worm gear. The first pinion  278 , the second pinion  282  and the worm gear  276  rotate about an axle  280  that is received in the openings  240  in the recessed surface  242  ( FIG. 9 ). The appendages  232  on the rear panel  222  lock the axle  280  and gears  276 ,  278  and  282  in place. For a left-hand configuration, such as that shown in  FIGS. 10-13  and  18 , the first pinion  278  engages a rack  284 . A removable tail  286  having a pin  288  extending in a direction perpendicular to the plane in which the rack  284  will move attaches to the rack. With reference to  FIGS. 14 and 15 , the rack  284  includes a V-shaped notch  290  at a lower end where the tail attaches. The tail  286  also includes a V-shaped notch  292 . The lower notch  290  of the rack  284  receives a portion of the tail  286  and the notch  292  in the tail  286  bears against a side of the rack  284 . A fastener  294  attaches the tail  286  to the rack  284 . The notches  290  and  292  allow the tail  286  to fasten to the rack in two different orientations to allow the rack to operate a left-hand and right-hand rotary deadbolt.  
      With reference back to  FIGS. 10-13 , the axially elongated gear  272  is driven by the transmission described above in the automated lock assembly A or another suitable transmission. The elongated gear  272  drives the worm  274 , which drives the corresponding worm gear  276 , which is attached to the second pinion  278 . The second pinion  278  engages the rack  284  moving the rack vertically and linearly.  
      The deadbolt  270  is somewhat L-shaped and includes a first circular opening  296  ( FIG. 9 ) that receives a pin  298  about which the deadbolt  270  will rotate. The deadbolt  270  is dimensioned to protrude through either cut-out  238  in the housing  210  so that the rotary deadbolt assembly E can be configured for a right-hand or left-hand door. The deadbolt  270  includes an elliptical opening  300  radially aligned with the circular opening  296  and pin  298  that receives the pin  288  extending from the rack  284 .  
      With reference back to  FIG. 9 , a spacer  304  mounts in the housing  210  attaching to the front wall  212  via a fastener  306  received in a fastener opening  308  of the spacer. The spacer  304  spaces the rotary deadbolt  270  from the first wall  212  of the housing  210  to allow the rack  284  to move between the rotary deadbolt  270  and the first wall  212 . The spacer  304  also includes an aperture  310  that is dimensioned to receive the pin  298  about which the rotary deadbolt  270  rotates. As most easily seen in  FIG. 11 , the spacer  304  includes a side notch  312  in which the tail  286  that extends from the rack  284  travels. The side notch  312  can provide a mechanical stop for the upward-most and downward-most linear movement of the rack  284  and can prevent unwanted torquing of the rack. As also noticeable in  FIG. 11 , the top cover member  254  includes two rear cut-out sections  314  in which the rack  284  can move to provide a linear track for the rack&#39;s movement to limit any undesired rotational movement.  
      The rotary deadbolt assembly can be configured in the field to provide for a right-hand or left-hand deadbolt assembly.  FIGS. 10-13  depict the gear train assembled in a left-hand configuration. To change to a right-hand configuration, such as that shown in  FIGS. 16 and 17 , the rack  284  is moved to engage the second pinion  282 . The tail  286  is removed from the rack  284  and reconnected in its other orientation. Both the spacer  304  and the rotary deadbolt  270  are flipped  1800  and now the rotary deadbolt can rotate towards the right, as depicted in  FIGS. 16 and 17 .  
      With reference to  FIG. 19 , a linear deadbolt assembly F will be described. Many of the components used in the linear deadbolt assembly can also be used in the rotary deadbolt assembly E. Furthermore, it is desirable for the ease of manufacture, as well as to provide the end-user multiple environments where the deadbolt assembly can be used, to use many of the same components in each of the linear deadbolt assembly F and the rotary deadbolt assembly E. Accordingly, many of the reference numerals used to describe the rotary deadbolt assembly E will also be used to describe the linear deadbolt assembly F. Nevertheless, it is to be understood that other configurations can be used for each of the assemblies and usage of the same reference numerals is only for the convenience of the reader.  
      The linear deadbolt assembly F includes a housing  210 , a front wall  212  and a rear wall  218  similar to the rotary deadbolt assembly E. Also, a gear mounting chassis  214  attaches to a cylindrical boss  216  using fasteners  215 . A removable rear panel  222  attaches to the rear of the housing  210 . The removable rear panel includes openings  224  that align with openings  226  in the housing  210  to receive fasteners  228  to selectively attach the removable rear panel  222  to the housing  210 . The removable rear panel  222  also includes appendages  232  that depend from the rear panel. As more clearly seen in  FIG. 20 , the housing  210  further includes a first side wall  234  and a second side wall  236 . The first side wall includes a rectangular cut-out  238 . A recessed surface  242  is formed in the first side wall  234  adjacent an upper edge of the rectangular cut-out  238 . Similarly, a second cut-out  246  is also provided in the second side wall  236  and aligns with the first cut-out  238 . Each cut-out  238  includes an opening  240 . In this embodiment, two side wall covers  244  can be provided to cover each cut-out  238  and  246 .  
      The housing  210  also includes a top wall  248  in which a top cut-out  252  is formed. In this embodiment, however, a linear deadbolt  320  selectively extends from the top cut-out  252 , as seen in  FIG. 22  and which will be described in more detail below.  
      Mounting screws of different lengths  262  are received in openings  264  in the housing  210  and also in openings  166  ( FIG. 19 ) in the housing  10  of the automated lock assembly A to selectively attach the linear deadbolt assembly F housing  210  to the automated lock assembly housing  10 .  
      The linear deadbolt  320  is driven by a transmission including the axially elongated gear  272 , the worm  274 , the corresponding worm gear  276 , the first pinion  278 , the second pinion  282 , and the axle  280  each of which were described above with relation to the rotary deadbolt assembly E.  
      With reference to  FIGS. 23-26 , the input gear  272  drives the worm  274 , which drives the worm gear  276 , which drives the attached pinions  278  and  282 . The pinions  278  and  282  engage a double rack  322  that depends from and is attached to the linear deadbolt  320 . The double rack  322  includes two racks that are spaced apart from one another such that the worm gear  276  does not contact either rack. In alternative embodiments, only one rack may be provided. Accordingly, the worm assembly translates rotational movement of the input gear  272  into linear movement of the deadbolt  320 . The rack  322  is long enough to allow the deadbolt  320  to extend from the top cut-out  252 , as shown in  FIG. 21 . In each embodiment, the input gear  272  and the worm  274  are attached to one another and concentric with one another. Also, the worm gear  276  is attached to each pinion  278  and  282  and concentric with each pinion.  
      The assemblies were defined with reference to preferred embodiments. Obviously modifications will occur to others upon reading and understanding the preceding description. The invention is intended to cover all modifications that come within the scope of the appended claims and their equivalents.
