     BACKGROUND OF THE INVENTION 
     The present invention relates generally to a locking apparatus, and more specifically, it relates to a locking apparatus for securing at least one structure or a plurality of structures used with a utility service enclosure, or for example, a watthour meter socket ring to prevent the separation of two opposing members of the watthour meter socket box ring, or used to seal tbr example, a trucking, shipping, an airline or other transportation or security container. 
     In the electric utility industry, for example, a locking apparatus or seal is useful to secure access panels of enclosures containing electrical or metering equipment. Such a locking apparatus or seal also ideally includes tamper-evident features to indicate unwanted tampering with the seal or attempts to access a secured electrical meter box or the like. 
     Electrical service providers generally deliver electricity to their customers via power lines buried underground or distributed along poles or towers overhead. The provider&#39;s power lines are usually distributed from a power generation station to numerous sets of customer lines, so that customers can then use the power to satisfy their various electrical needs. To measure delivered power so that customers can be billed in proportion to their usage, service providers typically terminate their power lines at a customer&#39;s home or business facility through a metered socket box, various designs for which are well known. 
     A meter box is generally used by electric utility companies, however the invention herein may be used with other utility service enclosures in the gas, water, cable, TV utility industries, or in shipping or other industries as well. 
     An example of one previously known meter box consists of two sets of electrical posts, with a provider&#39;s transmission lines being connected to one set of posts, and the customer&#39;s service lines to the other set. In order to measure the amount of electricity a customer uses, the meter box is configured to accept a watt-hour meter or another electricity usage measurement device, which, when plugged into the socket box, permits transmission of electricity from the provider to the customer and allows the amount of transmitted electricity to be accurately measured, so that the provider can charge the customer for power usage at an appropriate rate. 
     Various designs and uses for watthour meters are also well known, and all such designs and uses are incorporated by reference into the teachings of the present invention. The present invention is also applicable in situations where the customer&#39;s service lines are routed from the meter box to a breaker box so that electricity can be distributed to multiple service locations using additional sets of electrical lines or wires. 
     Presently, there are various types of meter socket boxes, each distinguished by the manner in which the meter is secured in place once it has been plugged into an electrical socket disposed in the meter box. For example, a ringed-type meter box fitted with a flanged front cover is known, within which a watthour meter is disposed so that a head portion of the meter passes out through a flanged opening in the front cover. In this configuration, the meter is generally held in place using an annular, lockable sealing ring. However, with this type of design, high lock cost and operator “key control” may be a potential problem. Moreover this type of design may require the use of special tools and structures to secure a ring locking device and may require used of more than one hand to retain or engage the locking device. 
     In an attempt to overcome some of these shortcomings, there destructible locks that can be installed on ring-type meter socket boxes. Several examples of patents which disclose attempts to solve some of the above problems are set forth as follows. 
     U.S. Pat. No. 5,161,838 to Ely, et al., entitled “Locking Assembly,” is directed to a locking assembly adapted for locking first and second members together, the assembly including a housing member and a stud member, the housing member being adapted to receive the stud member and permanently lock the stud member in the housing member, the assembly including a frangible portion, such that a part of the assembly is adapted to be broken away from a remainder of the assembly to permit removal of the assembly from the first and second members. This reference is incorporated by reference herein. 
     U.S. Pat. No. 6,406,074 to Mahaney, entitled “Destructible Locking Device,” sets forth a locking device for interlocking two members having aligned openings extending therethrough. The device includes a hollow cap and a pin with an enlarged head at one end and a nose at the opposite end. The pin is insertable through the aligned openings of the members, with its nose received in interlocked engagement within the cap, and with the two members captured between the cap and the enlarged head of the pin. A frangible portion of the pin is severable in response to relative rotation between its nose and enlarged head to thereby destructively disassemble the locking device. This reference is incorporated by reference herein. 
     U.S. Pat. No. 5,413,393 to Georgopoulos et al., entitled “Destructible Locking Device,” is directed to a self locking reusable rod seal which includes a case hardened stamped frustro-conical member comprising a C-shaped section from which two like opposing arcuate segments are cantilevered. The member is located and secured for axial displacement in a frustro-conical bore of a case hardened steel housing. The segments have axially spaced ridges, the end most ones of which grip a rod in the bore thereof, the rod axially displacing the member when the rod is displaced in opposite directions relative to the housing. The rod has circumferential axially spaced grooves. The member ridges engage the grooves so as to be pulled by the axial displacement of the rod. The ridges and grooves are resiliently engaged and when the member is displaced toward one end of the housing bore, the ridges disengage and when the member is displaced toward the other end of the bore, the ridges are wedged against the rod grooves. The rod has a head at one end which with the seal lock a hasp therebetween by limiting displacement of the rod toward the one housing bore end. 
     There remains a need for a locking apparatus and method for securing at least one structure or a plurality of structures, used with a utility service enclosure, or for example, a meter box locking ring having, for example, flanged ends or used to seal for example, utility enclosures, meter boxes or trucking, shipping, airline or other transportation containers or enclosures. There is a need for a tamper-evident locking apparatus that is adapted to indicate tampering. There is also a need for a locking or securing device that can be “locked” without the need for special tools and “unlocked” only one time by using a special or complementary tool, such that when the locking apparatus is “unlocked,” it is rendered ineffective as a future locking device. There is a further need for a locking or securing device that may be retained or engaged using one hand. 
     Those of skill in the art will appreciate the example embodiments of the present invention which addresses the above needs and other significant needs the solution to which are discussed hereinafter.

     DETAILED DESCRIPTION OF THE INVENTION 
     Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views, the attached figures illustrate an apparatus for securing a plurality of structures or a portion of a utility service enclosure. For example, in one embodiment, the apparatus is used for securing a watthour meter socket ring so as to prevent the separation of two opposing members of the watthour meter socket box ring. The apparatus may be used for creating a tamper-evident seal by securably connecting a plurality of structures. The apparatus may also be used as a locking assembly with at least one structure as will hereinafter be explained in further detail. 
     Referring now to  FIG. 1 , there is shown a securing sealing ring  14  for a ringed-type meter box (not shown). In order to hold a meter (not shown) in place and prevent its removal from the meter box, both the meter and meter base incorporate a corresponding set of flanges (not shown) that are retained together with an annular, lockable sealing ring  14 . The lockable sealing ring  14  is designed to encase and captivate the corresponding flanges of the meter and base when the ends  11 A,  11 B of the sealing ring  14  are held or connected together. There are different types of lock devices for holding or connecting the ends  11 A,  11 B together. Most devices require a key in order to engage and disengage the sealing ring  14  from the meter and base; this type of lock device can be “locked” and “unlocked” multiple times. 
     Now referring to  FIG. 2 , there is shown one example embodiment for creating a tamper-evident seal by securably connecting a plurality of structures with each of the plurality of structures defining an aperture therein.  FIG. 2  shows a plurality of structures  11 A,  11 B having apertures  18 A,  18 B which may be any of a variety of structures. In one example embodiment, the plurality of structures comprise first and second ends  11 A,  118  of a ring  14 , which may be connected or disconnected, the ring being adapted to mount a meter to a meter box structure (not shown). Each of the first and second ends  11 A,  118  of the ring  14  define apertures  18 A,  18 B therein respectively. 
     Referring now to  FIGS. 1-3 , there is shown a locking pin  2  with the locking pin having a distal end  5 A insertable through each of the apertures  18 A,  18 B of the plurality of structures. In the embodiment shown in  FIG. 3 , the distal end  5 A is adapted to be insertable through each of the apertures  18 A,  18 B of the first and second ends  11 A,  11 B of the ring  14 . The locking pin  2  comprises a head member  6  having at least an engageable end  9 A and a fracturable member  17 . The locking pin  2  further comprises a shaft portion  5  having the distal end  5 A. In the embodiment of  FIG. 3 , the fracturable member  17  is disposed intermediate the engageable end  9 A and the distal end  5 A of the locking pin  2 . However, the fracturable member may also be disposed so as to be formed integrally with the engageable end of the head member. It should be noted that the fracturable member may also be a frangible or breakable member or any other structure having like characteristics. 
     As shown in  FIGS. 2-3 , a lock housing  3  is adapted to retain at least a part  5 B of the shaft portion  5 , with the plurality of structures or first and second ends  11 A,  11 B being securably connected between the head member  6  of the locking pin  2  and the lock housing  3 . 
     In one example embodiment, the lock housing  3  preferably has a longitudinal bore therein defining an opening  49  in communication with a cavity  12 . The lock housing  3  further comprises a retaining member  4  disposed within a cylindrical groove  13 . The cylindrical groove  13  ideally incorporates a sloped surface  16 . 
     As the shaft portion  5  of the locking pin  2  is inserted through the apertures  18 A,  18 B of sealing ring  14 , and then into the opening  12  of the lock housing  3 , the shaft cylindrical groove  15  disposed on the locking shaft portion  5  is adapted to receive the retaining member  4 , thus retaining the locking pin  2  to the lock housing  3 ; this is the “locked” position. The flanges  11  of the sealing ring  14  are captivated between the head member  6  of locking pin  2  and the lock housing  3 . In one example embodiment, the locking pin  2  is permanently affixed to the lock housing  3 . 
     In another example embodiment, shown in  FIG. 15 , a retaining pin  11 D comprising a shaft portion  55  and a head portion  57 , is inserted through apertures disposed in flanges  11 C,  11 D. An aperture  18 C is disposed in shaft portion  55  in a generally perpendicular configuration. When the locking pin  2 A and the lock housing  3 A are installed through the aperture  18 C, the flanges  11 C,  11 D are captivated between the head portion  57  and the installed locking pin assembly  2 A, 3 A. In this embodiment, the number of flanges to be captivated are not limited to two. The retaining pin  11 D and the locking pin assembly  2 A, 3 A may be installed in a single flange, or multiple flanges, depending on the application. 
     Once in the “locked” position, as shown in  FIG. 2 , if an attempt is made to separate the locking pin  2  from the lock housing  3 , the sloped surface  16  urges the retaining member  4  in a radial direction toward the shaft cylindrical groove  15 ; this ensures constant retaining member  4  engagement with the shaft cylindrical groove  15 , preventing the separation of the locking pin  2  from the lock housing  3 . 
     It should be appreciated, that shaft portion  5 , or at least a part (hereof, as shown in  FIG. 2  may be retained or engaged with the lock housing  3 , for example, by hand without the use of a tool. 
     In another example embodiment shown in  FIG. 14 , lock housing cavity has an end wall  51  selectively displaced from the cavity opening such that the distal end  5 A of the shaft portion  5  bears against the end wall when any undesired generally translational force is transmitted to the engageable end  9 A; such a configuration helps prevent an undesired force from being transmitted to the fracturable member  17  and possibly breaking it to defeat the locking apparatus. That is, the lock housing  3  is in functional cooperation with at least a part  5 B of the shaft portion  5  such that the distal end  5 A of the shaft portion is adapted to bear against the lock housing  3 . In this way, the lock housing  3 , rather than the fracturable member  17 , receives any undesired generally translational force transmitted through the engageable end  9 A so as to prevent unintended breaking of the fracturable member. 
     Referring now to  FIGS. 2-4 , at least a portion of head member  6  has an outer surface  8 ,  21  adapted to receive at least two opposing forces being of sufficient magnitude to break the fracturable member  17 . At least a portion of outer surface  8  of the head member is preferably an angled surface. In certain embodiments, a portion of the head member  6  or outer surface  8 , is adapted to receive a first force and the engageable end  9 A is adapted to receive a second force with the second force opposing the first force. The first and second forces are preferably applied by a complementary tool described in further detail hereinafter. The first and second forces are of sufficient magnitude to break the fracturable member  17 . That is, the head member  6  is adapted to receive a resultant generally axial force against the outer surface  8 ,  21  of the head member such that the resultant generally axial force is of sufficient magnitude to break the fracturable member so that a part  38  of the head member comprising the fracturable member  17  may be pulled away from the engageable end  9 A. In this way, the part  38  of the head member with the fracturable member  17  is adapted to separate from the engageable end  9 A and the shaft portion  5  such that the plurality of structures or ring ends  11 A,  11 B may be disconnected. 
     It will be appreciated that the angular surface  8  prevents a common prying or pulling device such as a “gear puller” from gripping the engaging flange  7  in an attempt remove the ring portion  19  from the shaft portion  5 . 
     Turning now to  FIGS. 5-6 , an example embodiment of the invention is shown, comprising a complementary tool  31 , or lock assembly removal tool, which is adapted to manipulate the head member  6  outer surface to break the fracturable member  17 . The complementary tool  31  comprises, an actuator housing  39  defining an encapsulating cavity  29  having an interior surface  41  adapted to capture the head member  6 . The outer surface  8 ,  21  of the head member  6  is configured so as to be complementary to the interior surface  41  of the encapsulating cavity  29 . 
     Referring to  FIGS. 5-10 , and  13 , in one example embodiment, the complementary tool  31  is comprised of first and second actuating handles  23 A,  23 B, a base member  27 , a pivoting member  22 , two pivot pins  30 ,  34 , an actuating pin  26 A, a force-exerting member  24 , and a spring member  33 . The actuating handles  23 A,  23 B are securely fastened to the base member  27 , and the pivoting member  22 . The base member  27  and the pivoting member  22  are preferably joined and rotatably communicate through a common fulcrum defined by apertures  35  and  37 , and pivot pin  30  (as shown in  FIG. 13 ). A pin  34  passes through the force-exerting member  24 , and the opposing apertures  35  disposed on the pivoting member  22 . This captivates the force-exerting member  24  between two flanges on the pivoting member  22 , allowing the force-exerting member  24  to pivot. The first handle  23 B may be mounted such that it freely rotates or is frictionally pivotable or rotational. 
     The first handle  23 A is preferably fixedly connected to the actuator housing  39  and the second handle  23 B is pivotably connected to the actuator housing. Both the first and second handles  23 A,  238  could also be detachably mounted to the actuator housing to foster ease of storage and the like. 
     The second handle  23 B is preferably in functional cooperation with the actuator housing  39  with the actuator housing adapted to capture the head member  6  and to bear against the engageable end  9 A to break the fracturable member  17  when the second handle is actuated. In an example embodiment, the second handle  23 B is preferably adapted to be pivoted away from the first handle  23 A to an open configuration or position. In the open configuration, the actuator housing  39  is adapted to capture the head member  6 . Then, in response to a force applied to the second handle  23 B, the second handle  23 B is adapted to pivot toward the first handle  23 A to a closed configuration or position. In the closed configuration, the actuator housing  39  is adapted, as mentioned above, to in general, axially bear against the engageable end  9 A so as to break the fracturable member  17 . 
     With such a configuration, complementary tool  31  is usable with one hand to manipulate the head member  6 . 
     Turning in particular to  FIGS. 7-10 , in certain embodiments, the actuator housing  39  comprises a force-exerting structure  43  adapted to convert a pivoting rotational force to a generally translational force so as to in general, axially bear against the engageable end with the force being of sufficient magnitude to break the fracturable member  17 . 
     In an example embodiment as shown in  FIG. 8 , the force-exerting structure  43  comprises a force-exerting member  24  and a force-responsive member  26 . In one example embodiment, the force-exerting member  24  is a cam-like structure or cylinder and the force-responsive member  26  is an actuating pin. 
     The force-exerting member  24  is preferably adapted to be carried along a curved path and simultaneously rotate or roll during engagement with a surface  25  of the force-responsive member  26  when the second handle  23 B is pivoted towards the closed configuration. The three-responsive member  24 B is adapted for generally translational movement during engagement by the force-exerting member  24  so as to transmit a resultant generally translational force to the engageable end  9 A. 
     It should be noted that, in response to a force applied to the first and second handles  23 A,  238 , the first and second handles and actuator housing  39  are cooperatively adapted to transmit a mechanically multiplied generally translational three to the engageable end  9 A. With such a configuration, the force is of sufficient magnitude to break the fracturable member  17 . 
     In view of the above configuration, it will be appreciated that, the head member  6  is adapted to be manipulated by selectively hearing only against the head member rather than the head member and another structure, such as for example, one of the rings  11 A,  11 B or the lock housing  3 . 
     The head member  6  is also adapted such that it may be manipulated from only one side of the rings  11 A,  11 B or other plurality of structures connected or held together. 
     Referring again to  FIG. 4 , after manipulating the head member  6  and breaking the fracturable member  17 , the encapsulating cavity  29  of the actuator housing  39  is adapted to securely confine the remaining part  38  of the head member  6 . In this way, the head member can be captured or held within the tool after using the tool to manipulate the head member. 
     In an example embodiment, the second handle  23 B is frictionally pivotable with respect to the actuator housing  39  so as to prevent unwanted pivoting of the second handle to an open position. With this configuration, the part  38  of the head member  6  is prevented from being inadvertently released after head member is manipulated and the fracturable member  17  is broken. 
     It will also be appreciated that in another embodiment, the second handle  238  is pivotable to a stowed configuration, with the second handle  23 B being substantially aligned with the first handle  23 A so as to facilitate storage and handling. 
     In an alternate embodiment, the complementary tool may comprise the actuator housing without the actuating handles. That is, the actuator housing  39  may have a modular construction and comprise a power source for actuation so as to manipulate the head member. The power source may be electric or some other power source as would be understood by one of skill in the art. 
     Referring again to in  FIGS. 2-4 , the head member  6  of locking pin  2  further comprises a structural element  9 B adapted to displace a surface  21  of the engageable end  9 A away from the fracturable member  17 . With such a configuration, structural element  9 B serves as an anti-tampering element adapted to distance and protect the fracturable member from the engageable end so as to prevent undesired access to the fracturable member. That is, the material of the structural element would essentially have to be drilled out in order to gain access to and attempt to tamper with fracturable member to break it. 
     In one example embodiment, the structural element  9 B comprises a cylindrical standoff member adapted to displace the engageable end from the fracturable member by a selected distance so as to prevent tampering with the fracturable member. in another embodiment, at least a portion of the head member is hardened to further deter attempts to defeat the locking assembly. 
     In other embodiments, however, the surface  21 A of the engageable end  9 C could be integrally formed with and lie substantially in the same plane as that defined by the fracturable member  17 B, as shown in  FIG. 16  For example, in an example embodiment, the engageable end could be formed with the fracturable  17 B such that there is only a part of or no head section  6 A. 
     In another embodiment, the fracturable member is disposed immediately adjacent at least one of the plurality of structures. Such a configuration helps to minimize access to and deter tampering with the fracturable member  17 . 
     Turning again to  FIG. 2 , in one embodiment, the head member  6  has at least an engageable end  9 A and fracturable member  17 . The head member may also comprise a head section  6 A having at one end the engageable end  9 A, and fracturable member  17 . The head section GA preferably comprises a ring portion  19  which has a flanged portion  7  having an angular surface  8 . and structural element  9 B (or a cylindrical portion) which serves as a force-bearing portion with one end as the engageable end  9 A. The structural element  9 B is preferably disposed within the ring portion  19  so as to define a circumferentially extending channel  10  therebetween. In one embodiment, the fracturable member is interposed between the shaft portion  5  and a head section GA. However, in other embodiments, the fracturable member may be interposed at different positions. In certain example embodiments, the fracturable member is interposed between, the shaft portion and engageable end or disposed at the engageable end, 
     In one example embodiment, the locking apparatus creates a tamper-evident seal by securably connecting a plurality of structures, such as for example, ring ends  11 A,  11 B. Each of the ring ends preferably defines an aperture  18 A,  18 B therein. The locking pin is insertable into each of the apertures  18 A,  18 B and preferably comprises a shaft portion, a fracturable member, and a head section having an engageable end. The lock housing is adapted to retain at least a part of the shaft portion, with the ring ends connected between a portion of the locking pin and the lock housing. The head section has a structural configuration adapted to receive at least two opposing forces being of sufficient magnitude to break the fracturable member. 
     In use, as shown in the example embodiment of  FIGS. 5-8 , and  13 , the encapsulating cavity  29  disposed on the base member  27  of the complementary tool, or lock removal tool  31 , is adapted to receive the head member  6  of the locking pin  2 . As the handles  23  are urged apart, the base member  27  and the pivoting member  22  of the lock removal tool  31  are pivoted about the pivot pin  30 . The force-exerting member  24  is urged away from the actuating pin  26 . The spring member  33  urges the actuating pin  26  toward the force-exerting member  24 , allowing the head portion  6  of the locking pin  2  to freely enter the encapsulating cavity  29 . 
     As shown in  FIGS. 9 and 10 , the head member  6  is inserted into the encapsulating cavity  29 . An angular surface  28  disposed on base member  27  is adapted to securely retain the engaging flange  7  disposed on ring portion  19  of the head member  6 . 
     As the handles  23 A,  23 B are urged together, the base member  27  and the pivoting member  22  of the lock removal tool  31  are pivoted about the pivot pin  30 . The force-exerting member  24  is urged toward and bears on the surface  25  of actuating pin  26 . As briefly mentioned above, the force applied to the actuating handles  23 A,  238  is preferably mechanically multiplied and translated to the surface  21  of the structural element or cylindrical portion  9  of the head member  6 . When the force applied to the surface  21  of the cylindrical portion  9  by the actuating pin  26  is greater than the ultimate strength of the fracturable portion  17 , the ring portion  19  will separate from the remainder of the shaft portion  5 , allowing the removal of the remainder of the lock assembly from the sealing ring  14 . 
     Various other example embodiments provide an apparatus that may be adapted for use on a utility service enclosure. Such a utility service enclosure is used not only in the electric utility industry (e.g., a meter box) but also in the gas, water, cable, TV utility industries or in other utility industries. 
     In another embodiment an apparatus is provided for creating a seal. A locking pin is adapted to unite a plurality of structures. One example of such structures would be the ends of meter ring having apertures  18 A and  18 B as shown in  FIGS. 1 and 2 . However, the locking pin could also be configured to be used to unite a plurality of plates having apertures, engageable protrusions, or other engageable structural configurations such that the plates could be united with a fracturable locking pin of various configurations. A lock housing is adapted to retain at least a part of the fracturable locking pin such that the plurality of structures would be securable between a portion of the fracturable locking pin and at least a portion of the lock housing. The portion of the fracturable locking pin is also adapted to receive direct application of opposing forces by a separate object, whereby the fracturable locking pin (such as in one example embodiment shown in  FIG. 1 ) may be fractured, 
     In another example embodiment a stress-concentration member is adapted to concentrate stress at a desired location on the locking pin. An example of a stress-concentration member may be the fracturable member  17  as shown in  FIG. 3 . 
     In another example embodiment a further stress-concentration member is also adapted to concentrate stress at a desired location on the fracturable locking pin. In this way, the fracturable locking pin may be fractured with a desired fracture configuration. 
     As shown in  FIGS. 17A-17D , the fracturable locking pin  2 C further comprises a shaft portion  46 ,  48 , and wherein the further stress-concentration member comprises a groove  40  formed in at least a portion of the shaft portion. In one example embodiment, the further stress-concentration member comprises a groove formed in the shaft portion  46 ,  48 . In another example embodiment, the further stress-concentration member comprises an annular groove  40  formed in the shall portion. Ideally, the fracturable locking pin comprises first and second shaft sections  46 ,  48 , a fracturable member (in one embodiment, e.g.,  17 ) disposed between the first and second shaft sections, and a head section. The further stress-concentration member is adapted to concentrate stress on the fracturable member in a region within a projected area of the second shaft section  48 . In one embodiment this may be in a region within a projected area of the diameter of the second shaft section  48 . The further stress-concentration member to concentrate stress on the fracturable member is preferably in functional cooperation with the relative diameters of the first and second shaft sections  46 ,  48 . 
     In other words, this further stress-concentration member favorably affects the broken burr left after the fracturable member is broken (e.g., see  FIG. 4 ) and may foster clearance of the broken shaft through the aperture  18 A. The stress-concentrating features allow control over breakable region along shaft. This may also be viewed as intermediate-recess along the shaft or shaft diameter-reduction feature. In an example embodiment, the first shaft section outside diameter is in cooperation with the fracturable member outside diameter which is in turn in cooperation with the intermediate cooperative recess with provides fracture-configuration (or configurable-fracture) features for controlling the configuration, shape and size of the breakage of the fracturable member with respect to the shaft. Fracturable member is preferably disposed intermediate the ends of the locking pint the reduced diameter is preferably immediately adjacent the fracturable member so as to foster controlling the location of fracture by creating a locally reduced shaft diameter. 
     In another embodiment, a fracture-configuration-control member is adapted to control the configuration of fracture of the fracturable locking pin. In one embodiment this is the further stress-concentration member may be configured for controlling the characteristic of the fracture. 
     In another embodiment, the portion of the fracturable locking pin  2 C comprises a head member  42  disposed substantially near an outer side of one of the plurality of structures (not shown). The portion of the fracturable locking pin in another embodiment preferably comprises a head section and an engageable end near (e.g.,  44  in  FIG. 17A ). 
     Various other example embodiments provide an apparatus or tamper-evident seal that may be adapted for use on a utility service enclosure, transportation or cargo containers or on other enclosures needing a tamper-evident seal and locking apparatus. Moreover, a utility service enclosure or other containers, for example, may have various configurations, shapes and sizes and be used in the electric utility industry, (e.g., a meter box) as well as in the gas, water, cable, TV utility industries or in the shipping or transportation industries. 
     Turning now to  FIGS. 18 and 19 , another example embodiment is provided which includes tamper-evident features. A seal  101  comprises a fracturable locking pin  102  which is adapted to unite a plurality of structures. One example of such structures would be the ends of meter ring having apertures  118 A and  118 B as shown in  FIGS. 18 and 19 . However, the locking pin could also be configured to be used to unite a plurality of structures, used with a utility service enclosure, or for example used to seal or create a tamper-evident seal to indicate tampering with, for example, utility enclosures doors, lids or other secured panels, meter boxes, or trucking, shipping, airline or other transportation or cargo containers or other enclosures. The plurality could include plates having apertures, engageable protrusions, or other engageable structural configurations such that the plates could be united with a fracturable locking pin of various configurations adapted to fit security enclosures used various industries. 
     As shown in  FIGS. 18 and 19 , the seal  101  further comprises a housing  103  adapted to retain at least a part of the fracturable locking pin  102 . In one embodiment, a plurality of structures  111 A and  111 B is securable between a portion  106 E of the fracturable locking pin  102  and the housing  103 . To release the plurality of structures, the portion  106 E of the fracturable locking pin is adapted to receive direct application of opposing forces by a separate object, whereby the fracturable locking pin may be fractured. For example, in one embodiment, the separate object may be a tool adapted to fracture the fracturable locking pin. In other embodiments, the fracturable locking pin may have a fracturable portion configured such that it may be fractured by hand (e.g., without the use of a tool or the like). 
     The seal  101  as illustrated in  FIGS. 18-19 ,  21 - 22 , seal  101  further comprises an indication member  150  adapted to reveal evidence  117 A- 117 D of any application of force to the indication member. 
     In another example embodiment of the seal, the indication member  150  comprises a coating adapted to encapsulate at least some of the fracturable locking pin  102 . The fracturable locking pin  102  is preferably at least partially surrounded with the indication member  150 . 
     Another example embodiment of the seal includes an indication member  150  which further comprises a stress-propagation member  102 A, as shown in  FIG. 19  adapted to selectively propagate any stress resulting from application of force to the indication member. In this way, evidence of any application of force to the indication member may be more clearly revealed. In one embodiment, the stress-propagation member further comprises a protuberance  102 B disposed on the portion  106 B of the fracturable locking pin. 
     As shown in  FIGS. 18-20 , in an example embodiment, the portion of the fracturable locking pin comprises a head member  106  having a central region  1020 ; the protuberance may, for example, being integrally formed with the indication member and disposed proximate the central region. 
     In another example embodiment of the seal, the portion  106 B′ shown in  FIG. 20  of the fracturable locking pin further comprises a head member stress-concentration element  102 D disposed in functional cooperation with the indication element  150 ′ to impede propagation of any stress resulting from application of force to the indication member  150 ′, wherein evidence of any application of force to the indication member disposed proximate the portion of the fracturable locking pin  102 ′ may be more clearly revealed. In an example embodiment, the portion of the fracturable locking pin further comprises a head member stress-concentration element integrally disposed in functional cooperation with the indication member. 
     Another example embodiment provides the portion of the fracturable locking pin comprises a head member having a central region  102 C. A head member stress-concentration element  102 D is ideally configured to concentrate, or in another embodiment localize, proximate the central region  102 C of the head member  106 ′ any stress resulting from application of opposing forces. 
     In another example embodiment of the seal, the housing  200  such as shown in  FIG. 22A  in cross-section, further comprises a retainer  201  having a retaining member  202  and a retaining member recess  203 , the retaining member recess adapted to retain the retaining member. 
     In the example embodiment of the seal shown in  FIGS. 22A and 22B , the retaining recess  203  is formed in part by a first wall of the retainer  204 , the first wall being in spaced in opposing relation to an inclined wall  205  oriented at an angle with respect to the first wall and a central bore  206  of the retainer  201 , and wherein the first wall is in functional cooperation with the inclined wall so as to reduce the clearance between the surface of the inclined wall  205  and the surface of the first wall of the retainer  204  the retaining recess when the retaining member. The retaining member  202  is retained within the retaining recess and the reduced clearance between the inclined wall  205  and the first wall of the retainer  204  act so as to foster hindering access and removal of the retaining member by pick tools. By reducing the amount of free play in the retaining recess the retaining member is hindered from moving sufficiently into the central bore  206  and reduces the amount of exposed surface area of the retaining member that would allow a picking tool to gab the retaining member in a substantial enough manner to allow it to be extracted from the retainer. A prior devices have been known to be vulnerable to removal of the retaining member. The removal of the retaining member could allow a dishonest person to install a seal that would appear to be properly installed but in reality could be removed without showing evidence of entry. 
     Referring to the detail view of  FIG. 22A  shown in  FIG. 22   b , the inclined wall  205  intersects a second surface  208  and is shown with a radius  209  generally at the intersection. This radius assists in camming the retaining member inward if an axial force is applied to a locking pin when it is installed in the recess. The action of an inclined surface with a locking pin in a seal is well known by those skilled in the art. By reducing the intersection point of the inclined surface  205  and the second surface  208  the inclined surface  20 S is still able to interact with the retaining member yet limits rotation of the retaining member out of the retaining recess and reduces access to a sufficient portion of the body of the retaining member to allow it to be grasped by a picking tool. 
       FIGS. 22A and 228  illustrate an embodiment of the invention and provides a width  211  for the retaining recess  203  generally along the axial direction of the central bore  206  of the retainer that is equal to the width of the retaining member along the axial direction of the central bore plus a fraction of the width of the retaining member along the axial direction of the central bore. This along with the reduced clearance between the first wall and the inclined wall act to reduce the free play of the retaining member and thus inhibit its un-authorized removal. 
     In other embodiments of the invention, a sharp corner, a chamfer or other transitional surface could be used in place of the radius  209  shown in  FIG. 22B . 
     In the embodiment shown in  FIGS. 22A and 22B , the first wall  204  of the retainer is part of a retaining member retainer  210 . The retaining member retainer in the current embodiment is pressed in place and held in assembly by frictional forces. Other embodiments be held in place using an adhesive, by crimping, staking welding or other suitable means as would be apparent to those skilled in the art of fastening. The retaining member retainer  210  holds the retaining member  202  in place during assembly and provides support for the retaining member  202  after the retainer  201  is installed in the housing  200 . 
     In an example embodiment of the seal, the housing further comprises a retainer having a retaining member and a retaining member recess, the retaining member recess adapted to retain the retaining member. 
     In another example embodiment of the seal, the retaining recess is formed in part by a first wall of the retainer, the first wall being in spaced in opposing relation to an inclined wall oriented at an angle with respect to the first wall, and wherein the first wall is in functional cooperation with the inclined wall so as to reduce the clearance between the retaining member and the retaining recess when the retaining member is retained within the retaining recess, so as to foster hindering access and removal of the retaining member from retaining recess. 
     As shown in  FIG. 19 , the fracturable locking pin  102  further comprises a spacing member  107 A adapted to space the portion of the fracturable locking pin  102  away from either a first or second end of a ring when secured between the portion of the fracturable locking pin and the housing. 
     Referring now to  FIGS. 21-30 , the fracturable locking pin  102  is adapted to be fractured by only bearing against the portion  106 B of the fracturable locking pin rather than the portion  106 E of the fracturable locking pin  102  and another structure. 
     In another example embodiment of the seal, the fracturable locking pin comprises a shaft portion  105  and a fracturable portion, the fracturable portion comprising a fracturable member  117 A and a head member having an engagement surface, and wherein the fracturable member is separable from the shaft portion when there is any application of force to the head member. 
     As shown in  FIGS. 21-30 , the portion  1068  of the fracturable locking pin  102  is adapted to receive at least two opposing forces, the at least two opposing forces being of sufficient magnitude to break the fracturable member. 
     One example embodiment further comprises a complementary tool  131  adapted to manipulate the head member  106 , wherein the at least two opposing forces of sufficient magnitude may be applied to break the fracturable locking pin. 
     Ideally, in an example embodiment shown in  FIGS. 23-31 , the complementary tool  131  comprises at least an actuator housing  139  defining a cavity  129  having an interior member  129 A adapted to capture at least a part of the head member  106 .

The actuator housing further comprises a force-exerting member  124  to in general, axially bear against the portion  106 B of the fracturable locking pin  102  to break the fracturable locking pin. The tool  131  ideally further comprises a cam surface  1240  which makes acuatc contact with force-exerting member  124 , as well as a housing, pivoting member  122 , two pivot pins  130 ,  134 , an actuating pin  126 A, and a spring member  133 . The tool further comprises actuating handles  123 A,  123 B to actuate the actuator housing. It will be appreciated that the tool  131  has several similar operational features to the tool as shown in  FIGS. 5-13  (e.g.,  28 - 31 , and in particular, page 29, lines 11-27). 
     Referring now to  FIGS. 32A-32D , various views of an embodiment of the fracturable locking pin are illustrated.  FIG. 33  is shows of an embodiment illustrating a seal with fracturable locking pin  102  prior to insertion into a housing  103  in accord with a possible embodiment of the present invention.  FIG. 34  is shows the fracturable locking pin  102  after insertion into a housing  103 . 
     In other embodiments, the housing includes a translucent outer enclosure and a colored inner enclosure with a bar code panel. Another embodiment provides a housing including a housing forming opening, and a contoured entry member as well as an end member.

     Referring again to the various figures, it should be recognized that in other embodiments, various reference characters (or numerals) designate the same or similar parts throughout the several views. Various reference characters (or numerals) in other figures have the same last one or two digits as those in  FIGS. 1-17D  (e.g.,  14  may be the same as  114 ); where indicated and in many cases as will be apparent to one of ordinary skill in the art, that a part shown in other figures which has the last two digits which are the same as designates the same or similar parts as those parts in  FIGS. 1-17D . 
     Other example embodiments related to a retaining apparatus for a seal are shown in, for example,  FIGS. 35A-35H . 
     Bolt type seals are used for many sealing applications as indicators to ensure that the contents of containers are not accessed without showing evidence. Some examples of containers are truck cargo trailers, shipping containers and electrical enclosures. In the electric utility industry these seals have been adapted to seal meter-sealing rings. Generally these bolt type seals comprise a housing and a locking bolt. The locking bolt is inserted into a locking bolt receiving aperture and is generally captured and retained by an internal retaining member. In many sealing applications once the locking bolt is inserted into the housing, the bolt type seal must be destroyed to open the container. Many current bolt type seals use a split ring to retain the locking bolt in the housing. Typically when the locking bolt is inserted into the housing, one end of the bolt passes through the split ring camming it outward sufficiently to allow the locking bolt to pass through. An annular groove is provided on the end of the locking bolt and the split ring snaps into this groove uniting the housing and the locking bolt. One problem that has been a concern for users of bolt type seals is that the split ring can be removed from the housing allowing the bolt to be inserted and removed without showing any evidence of tampering. Someone desiring to gain access to a sealed enclosure can modify a housing by removing the split ring and freely access the container without showing signs of tampering, yet the enclosure appears to be properly sealed when the locking bolt is in place. 
     The present invention comprises a seal, the seal comprising: a housing; a locking bolt; and a locking bolt retainer, the locking bolt retainer comprising a locking bolt gripping portion and a housing gripping portion; wherein the housing gripping portion comprises a locking bolt receiving aperture interfering portion. 
     One example embodiment bolt type seal is shown in  FIG. 35A  and comprises a housing  1  and a locking bolt.  FIG. 35B  shows the present embodiment installed on a meter sealing ring  3 . The locking bolt  2  is inserted through a hole in the ring  3  generally at  4  and the ring is held closed by the housing  1  and locking bolt  2 . Once the seal is installed it must be destroyed to open the meter sealing ring. The present embodiment may be to seal many different devices as will be obvious to those skilled in the art and is shown in  FIG. 35B  as simply an example sealing application. 
       FIG. 35C  shows an example embodiment seal in cross section.  FIG. 35C  shows the housing  1  which comprises a locking bolt receiving aperture  6 . The locking bolt receiving aperture accepts a locking bolt  2 . The locking bolt comprises a shaft portion  17  a head portion  18  and a circumferential grove  16 . A locking bolt retainer  7  is located generally along the central axis of the locking bolt receiving aperture. Referring to  FIG. 35E , the locking bolt is inserted into the locking bolt receiving aperture and into the locking bolt retainer, the locking bolt retainer captures the locking bolt and securely grips it. The gripped configuration is shown in  FIG. 35F . Once the locking bolt is gripped by the locking bolt retainer the present invention requires either the locking pin or the housing or both to be destroyed in order to open the meter sealing ring. 
     Referring to  FIG. 35C , the locking bolt retainer can be seen generally at  7 . The locking bolt retainer comprises a bushing  8  and a fastening member  9 . The fastening member further comprises an interfering portion  10 ; a flexible connecting portion  11  and a locking pin interacting portion  12 . The bushing comprises a locking bolt receiving aperture  13 , a fastening member closing portion  14 . 
       FIGS. 35D-35F  show the sequence of operation of the seal. To begin the locking bolt  2  is aligned with the locking bolt receiving aperture  6  and inserted into the aperture. When the end of the locking bolt contacts the fastening member  9  slight force is exerted to bend the flexible connecting portion  11  outward and allow the end of the locking bolt to enter the fastening member as shown in  FIG. 35E . Once the locking bolt is inserted sufficiently the locking pin interacting portion  12  can snap into the circumferential groove  16  In the locking pin as shown in  FIG. 35F . 
       FIG. 35G  shows the gripping action of the locking bolt retainer  7 . When sufficient force is exerted on the locking bolt to attempt to remove it from the housing, the fastening member  9  is pulled with the locking bolt as a result of interaction between the locking pin interacting portion  12  and the circumferential grove  16  in the locking bolt. As both members move they are drawn into the bushing  8  and the flexible connecting portion  11  is cammed inward by the fastening member closing portion  14 . The locking bold has tapered portion  19  as seen in  FIG. 35C . The tapered portion allows the flexible connecting portion to nest tightly against the locking pin and wedge into the bushing. Further tension on the locking pin forces the tapered surfaces against each other. The diameter of the end of the locking bolt at  20  shown in  FIG. 35C  is sufficiently large so that when combined with the thickness of the flexible connecting portion it provides an interference fit and prevents removal of the locking bolt from the housing. 
     Referring to  FIG. 35C , if an attempt is made to remove the fastening member from the housing, the interfering portion  10  of the fastening member would abut the bushing  8  generally at and since its diameter is larger than the diameter of locking bolt receiving aperture  13  in the bushing and the locking bolt receiving aperture  6  in the housing it will be prevented from being extracted. 
       FIG. 35G  shows another example embodiment. The example embodiment in  FIG. 35G  uses a disk shaped fastening member shown generally at  22 . The view in  FIG. 35G  shows the fastening member as it would appear with the bushing and housing members removed and with the locking bolt  23  inserted. The fastening member  22  of the current embodiment comprises an interfering portion  24 ; flexible connecting portions  25  and locking pin interacting portions  26 . 
       FIG. 36A  shows a cross-sectional view of another example embodiment seal installed in a locking ring  306 . The seal comprises a locking bolt  303 , a bushing  301  and a disk-shaped fastening member  302 , which in this example embodiment is a retaining washer, and is enclosed in a housing  307 .  FIGS. 36B and 36C  show the locking bolt  303 , bushing  301  and fastening member  302  with the housing and locking ring removed.  FIG. 36C  shows a cross-sectional view and  36 B shows a fully intact view. 
     The disk shaped fastening member  302  has splits shown for example, at  308  and material void areas such as  309  located circumferentially around the disk so as to increase the flexure of the retaining tabs an example of which is shown at  310 . The retaining tabs act to grip the locking pin and engage with the recess in the locking bolt  311  to prevent retraction of the locking bolt from the seal. 
     The bushing  301 , in an example embodiment, comprises a generally cylindrical body having a central bore to accept a locking bolt. The bushing further comprises a stress-distributing surface  304  adapted to engage at least a portion of the retaining member when the locking pin is retracted.  FIG. 36D  shows the bushing  301 , locking bolt  303  and retaining member  302  with the housing removed, in cross-section and in a condition where a force has been applied to the locking bolt to attempt to extract it from the seal. The retaining member is shown in a reversed flexural state generally at  312 . The stress-distributing surface  304  functionally cooperates with the at least a portion of the retaining member to increase the pull force required to retract the locking pin from the lock housing. The stress-distributing surface in the present embodiment is a chamfered edge on the bushing. In other embodiments the stress-distributing surface could be a radius or other shaped surface that will reduce the shear stress exerted by the bushing and the locking pin on the retaining member. 
     In another example embodiment, the locking bolt retainer comprises a split ring that is attached to a locking bolt receiving aperture interfering portion. The attachment on this embodiment comprises an elastomer material that is bonded to the split ring. The elastomer allows the split ring to flex to allow insertion and engagement of the locking pin yet keeps the split ring united with the interfering portion. Other example embodiments use a flexible filament attached to the interfering portion and the split ring. Still other example embodiments comprise flexible leaves spaced around the split ring attaching the split ring to the interfering portion. 
     One function of the interfering portion is to prevent the split ring from being removed from the housing. In the present embodiment shown in  FIG. 35C , the interfering portion  10  is a solid ring comprised of steel. Other example embodiments could comprise other metals, plastics ceramics, composites or other materials with sufficient strength to inhibit extraction through the locking bolt receiving aperture. 
     Other example embodiments could make use of interfering portions with other shapes. The embodiment shown in  FIG. 35C  shows a ring shape; other embodiments comprise a square, hexagon, octagon, triangle, star, or irregular profile. The specific shape of the interfering portion can take on numerous shapes that are of sufficient size and geometry to impede its extraction through the locking bolt receiving aperture. 
     In other example embodiments, bolt seals are used to secure many different enclosure types from truck cargo containers to electricity meters. Certain specifications require a bolt seal to withstand a significant axial tensile force. In one embodiment a tool is provided for breaking the head of a sealed bolt type seal. Due to the high tensile force requirements for these seals, a tool to shear the head of the bolt seal from the bolt must provide a significant amount of force on the head of the bolt to break it and allow its sealed contents to be accessed. 
     An example embodiment is shown in  FIGS. 35I-35M  and  35 O and comprises a body  4 , handles  1  and  7 , a cam  9  as shown in  FIG. 35N , a punch  10  and a ratchet mechanism  2 . Referring to  FIG. 35O , the cam  9  makes contact with a roller  6  that is mounted on the punch  10 . Force applied to the handles  1  and  7  creates a torque that is applied through the ratchet mechanism  2  to the cam  9 . The cam  9  has a gradually increasing diameter  13  or rise that bears on the roller  6  at  14  and forces the pin  10  into the head  3  of the bolt seal  5  in the bolt interacting portion  8  of the tool. The tool is positioned so that the head of the bolt is captured by the bolt interacting portion. As the pin  10  is acted upon by the cam  9 , the pin is forced deeply enough into the head of the bolt so as to shear the shank section  11  of the bolt from the head  3  of the bolt and thus allow removal of the seal from the container on which it is installed. In some example embodiments, the cam is designed so as to give mechanical advantage to reduce the force required to be placed on the handles to operate the tool. In the present embodiment the cam has a linear rise over approximately 300 degrees. Once the cam is fully rotated and the head of the bolt has been broken the cam returns back to its starting position and the punch returns to its fully retracted position. A spring  15  is mounted coaxially around the pin in the cavity of the body  4 . The spring  15  assists in retracting the pin after the bolt seal is broken. 
     Many different ratchet devices may be used to drive the earn as will be obvious to those skilled in the art. Many different profiles may be chosen for the cam. A part of the function of the cam in some embodiments is to actuate and allow return of the punch at varying rates and angles of rotation.
