Description
- This patent application is a continuation of U.S. patent application Ser. No. 13/331,001, entitled “Fastener Attachment System and Methods of Use”, filed on Dec. 20, 2011, the contents of which are hereby incorporated by reference herein in its entirety.
- An overhead power line consists of electrical conductors suspended by insulators attached to towers or utility poles. Since most of the insulation is provided by air, overhead power lines are generally the lowest cost method of transmission for large quantities of electric energy. Commonly, overhead lines use bare aluminum conductors or aluminum conductors with a steel core. The conductors are supported and attached to the towers/wood pole structures via glass, ceramic, or polymer insulators. At the terminal ends of each line (generally at a substation or switching station), the conductors are commonly dead-ended and routed through disconnect switches and breakers so that the line can be de-energized for maintenance. In addition, in some instances, lines are tapped and routed to another substation or switching station. At these tap locations, the conductors are dead-ended and generally routed through disconnect switches so that the tapped line can be de-energized for maintenance.
- Oftentimes, linemen need to perform maintenance on the transmission lines while the line remains energized. In particular applications, linemen may need to disconnect and re-attach hot jumpers to a disconnect switch located at a tap location or terminal end of a line. This can oftentimes be a difficult and tedious task to line up the jumper connector pad with the switch terminal connector or dead-end terminal connector pad, install the bolts, nuts, and washers, and tighten the connection. This can be a simple three minute job, if performed on the ground or on de-energized equipment. However, such work is frequently performed on energized equipment, in a bucket suspended well above the ground, using numerous, eight foot or longer, fiberglass hot-sticks. Factor in various wind and weather conditions making a single jumper connection that can take an hour or more to complete.
- Throughout history, the prior art has endured attempts by workmen to make the task of assembling conductor attachment components with one another using fasteners easier, safer and faster. Typically, the need arises, as discussed above, where the orientation or locations of the conductor attachment components on a structure or tower create a difficult and tedious task for the workmen. For example, workmen frequently have to apply fastener components, such as washers and nuts, to various conductor attachment components. Commonly, it is difficult for a tool to reach the area on a structure where conductor attachment components need to be coupled together with fasteners. This may be due to a great distance separating the workmen from the structure, by the configuration of the structure, or obstacles positioned between the workmen and the structure. All too frequently, the workmen will “engineer” a solution using various adhesives, tape, magnets, or even chewing gum in order to adhere fastener components to a tool so that the fastener components do not become disengaged from the tool until they have been initially applied to the conductor attachment component on the structure. Unfortunately, such on the spot solutions are impractical and unreliable. When such attempts fail, fastener components typically fall from the tool being used. When fastener components fall, it may be into a location where the fastener components can only be retrieved through a great expenditure of additional time and energy. Accordingly, a fastener attachment system is needed that is reliable and simple to use when attaching fasteners and fastener components.
- Many times, one or more conductor attachment components need to be secured together with a fastener, such as a threaded bolt, and opposing fastener component, such as a nut and washer. However, due to the location or orientation of the structure, it is difficult for the workmen to simply dispose the threaded bolt through an opening in the conductor attachment component and start the nut at the opposing end of the fastener. In such instances, prior art attempts to position threaded bolts and other fasteners that must be later secured include the use of tape, adhesives and the like. Such efforts have always met with mixed results at best. In particular, fasteners (bolts, nuts and washers) are frequently lost or, if retrievable, serve only to slow the workmen down. Moreover, such prior art attempts fail to provide any form of precision positioning of the fasteners before they are coupled with the structure. In particular, instances where multiple fasteners are required on a conductor attachment component, their distance with respect to one another may require a level of precision that simply cannot be attained through the use of tape, adhesives or other mechanical aids. Accordingly, what is needed is a jig assembly that can accurately position multiple fasteners simultaneously in a fixed orientation to a conductor attachment component so that a workman is free to engage separate tools for securing the fastener components.
- This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary, and the foregoing Background, is not intended to identify key aspects or essential aspects of the claimed subject matter. Moreover, this Summary is not intended for use as an aid in determining the scope of the claimed subject matter.
- The fastener attachment system of the present technology, in various embodiments, includes a socket assembly, which includes a socket body that is removably secured to the distal end portion of a hot-stick or other tool. The socket body forms the frame of the socket assembly. A spring blade assembly is positioned around the socket body and includes a blade retaining ring and a plurality of resiliently deformable retaining blades. The socket body and the blade retaining ring are coaxially aligned such that the blade retaining ring may move toward and away from an open first end portion of the socket body, along a length of the socket body. The retaining blades are each secured, from one end portion, with the blade retaining ring so that the opposite end portions of the retaining blades extend freely and outwardly from the blade retaining ring and the open end portion of the socket body. The second end portions of the retaining blades include tips that are angled inwardly toward a long axis of the socket body. Embodiments of the spring blade assembly also include a blade guide that is secured to the socket body such that one or more open pathways exist between the blade guide and the socket body. The retaining blades are disposed within the one or more open pathways, which are sized to permit sliding, longitudinal movement of the retaining blades. Movement of the blade retaining ring away from the open end portion of the socket body cause the blade tips to move toward one another and the open end portion of the socket body, partially obstructing the open end portion of the socket body. Movement of the blade retaining ring toward the open end portion of the socket body causes the blade tips to move away from one another and away from the open end portion of the socket body, exposing the open end portion of the socket body.
- Embodiments of the fastener system include a fastener jig that includes a jig frame. The jig frame includes at least one pair of opposing fastener jaws such that at least one of the fastener jaws is slidably movable between a releasing position and a securing position. A fastener jaw bolt is threadably coupled with at least one of the fastener jaws, such that rotation of the fastener jaw bolt in a first direction moves the fastener jaws toward the securing position and rotation of the fastener jaw bolt in a second direction moves the fastener jaws toward the releasing position. The fastener jig further includes opposing mounting jaws that are coupled with the jig frame such that they are movable between a releasing position and a securing position. The opposing fastener jaws are positioned between the pair of mounting jaws. A mounting jaw bolt is threadably coupled with the fastener jig, such that rotation of the mounting jaw bolt in a first direction moves the pair of mounting jaws toward a securing position. Rotation of the mounting jaw bolt in a second direction moves the pair of mounting jaws into the releasing position.
- In some methods of use, one or more bolts are placed, head first, within a bolt head channel between the fastener jaws and tightened so that the bolts extend outwardly from the bolt head channel and the fastener jig. The user may then couple the mounting jaw bolt with a tool, such as the hooked end portion of a hot-stick. The user then extends the hot-stick and fastener jig toward a first structure, such as a switch terminal connector pad, designated to receive the fasteners. The fasteners are guided through openings in the structure. Once a portion of the structure, such as the side edges of the connector pad, is between the mounting jaws, the mounting jaw bolt is rotated until the mounting jaws are in a secure position with respect to the structure.
- With the bolts securely positioned within the openings of the structure, a second user may grasp a second structure, such as a jumper connector pad, with another tool, such as a second hot-stick. The lengths of the bolts (already secured with the first structure) are passed through the pair of openings in the jumper connector pad. The first user may then remove his hot-stick from the mounting jaw bolt on the fastener and secure the hot-stick to the socket assembly. The first user may position the blade retaining ring closely adjacent the blade guide so that the retaining blades are placed in an open position. Fastener components, such as a nut, flat washer and spring washer may then be passed between the retaining blades so that they are disposed within the open interior of the socket body. The blade retaining ring is then withdrawn away from the blade guide, which compresses them toward one another and secures the nut within the socket body. With the socket assembly secured to the distal end of the hot-stick, the first user may then place the washers and nut onto the free ends of the bolts that are passing through the first and second structures. After the first user has loosely secured the washers and nut to one of the bolts, the first user may simply pull the socket assembly free from the washer and nut as the retaining blades are formed from a resiliently deformable material. The first user then repeats this step attaching washers and nuts to all of the required bolts. When all of the washers and nuts have been loosely secured, the first user may then exchange the socket assembly for a standard socket that may be extended toward the nuts for tightly securing the same about the bolts. Disassembly of the fasteners to separate the first and second structures from one another may be accomplished by reversing the assembly process.

These embodiments are disclosed in sufficient detail to enable those skilled in the art to practice the invention. However, embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. The following detailed description is, therefore, not to be taken in a limiting sense.
- The fastener attachment system of the present technology is provided in various embodiments, as described below, which may include one or more separate component parts that work with one another or separately within the fastener attachment system. It is contemplated that the fastener attachment system may be used to secure a wide array of different types of fasteners and fastener components. While the principle exemplary embodiments will include fasteners, such as threaded bolts and fastener components, such as various washers and threaded nuts, the fastener attachment system may be used with a nearly limitless array of fasteners and fastener components. Examples may include curved and straight bolts and locking pins, and various other mechanical fasteners that may be secured or initially secured through pushing, pulling, and rotating forces. Similarly, the embodiments disclosed below may specifically relate to examples of the coupling of equipment on energized transmission lines by one or more linemen. However, as those in the art will appreciate, the following fastener attachment system may be used in a limitless number of applications and industries.
- With reference to
FIGS. 1A-1E , one component of the fastener attachment system may include asocket assembly 10. In most embodiments, thesocket assembly 10 will include asocket body 12 having a long axis that extends through an openfirst end portion 14, which is in communication with an open interior portion 16. It is contemplated that various embodiments of thesocket body 12 will shape one or more interior walls of the open interior portion 16 to accommodate the shape of particular styles of fastener heads. For example, the depictedsocket body 12 is provided with an open interior portion 16 having a hexagonal cross section. In such embodiments, bolts or other fasteners having a hexagonal head shape are easily accommodated and manipulated by thesocket body 12. Asecond end portion 18 is positioned opposite the openfirst end portion 14 and will be provided with a shape specifically designed for operative engagement with a working end of a tool, such as common tool arms like socket wrenches and other industry-specific tools, such as a linemen's hot-stick. In any regard, thesecond end portion 18 may be provided with an interior that is shaped to have a square cross section to receive a lug or button extending from the desired tool. Other shapes are contemplated, including openings, that may pass through the side walls for passing one or more mounting pins that secure thesocket body 12 to the tool being used. - The
socket assembly 10 is further provided with aspring blade assembly 20. In various embodiments, thespring blade assembly 20 will include ablade retaining ring 22 and a plurality of resilientlydeformable retaining blades 24. Typically, theblade retaining ring 22 will be shaped to have an open interior through which thesocket body 12 may be disposed so that thesocket body 12 and the blade retaining ring are coaxially aligned with one another. In this orientation, theblade retaining ring 22 may be selectively moved toward and away from the openfirst end portion 14 of the socket body, along a length of thesocket body 12. The retainingblades 24, in various embodiments, are provided as elongated, narrow fingers, having afirst end portion 26 and an oppositesecond end portion 28. Thefirst end portions 26 of theretaining blades 24 are secured with theblade retaining ring 22 so that thesecond end portions 28 of theretaining blades 24 extend freely and outwardly from theblade retaining ring 22 and the openfirst end portion 14 of thesocket body 12. In various embodiments, thesecond end portions 28 of theretaining blades 24 are provided withtips 30 that are angled inwardly toward the long axis of thesocket body 12 when the retainingblades 24 are secured about a peripheral edge of theblade retaining ring 22. It is contemplated that the retainingblades 24 may be formed from nearly any material, according to the intended use and durability of the fastener attachment system. However, various grades of flat spring steel and other metals will provide the deformable resiliency that may be desired as discussed further below. It is contemplated, though, that other materials, including various plastics and the like, may be used in certain applications. - The
spring blade assembly 20 is further provided with ablade guide 32 that is shaped to have an open interior through which thesocket body 12 may be disposed, such that thesocket body 12 and theblade retaining guide 32 are coaxially aligned. In various embodiments, theblade retaining guide 32 is secured to thesocket body 12 in a manner that substantially limits the longitudinal movement of theblade guide 32 along the length of thesocket body 12. In at least one embodiment, a plurality of mountingpins 34 are positioned to extend outwardly from theblade retaining guide 32 and into thesocket body 12, such that the mounting pins 34 extend at least partially into the open interior portion 16 of thesocket body 12. In certain embodiments, such as depicted in the accompanying figures, a pair of mountingpins 34 are positioned directly opposite one another through theblade guide 32. In this manner, the mounting pins 34 may be coupled with the opposingblade guide 32 andsocket body 12 such that theblade retaining guide 32 is allowed to pivot slightly on the mounting pins 34 with respect to thesocket body 12. - In various embodiments, the plurality of retaining
blades 24 are disposed within one or moreopen pathways 36, which are defined by an interior surface of theblade guide 32 and exterior surface of thesocket body 12. In particular, the one or moreopen pathways 36 are sized and shaped to permit longitudinal sliding movement of the retaining blades therethrough. In various arrangements, each mountingpin 36 is positioned within gaps between pairs of retainingblades 24, causing the mounting pins 34 to glide between the retainingblades 24 throughout reciprocal movement of theblade retaining ring 22 and retainingblades 24. - In various embodiments, the
socket assembly 10 is provided with acompression spring 38 having a long axis that is coaxially disposed within the openinterior portion 14 of thesocket body 12. Afirst end portion 40 of thecompression spring 38 is coupled with aninterior wall 42 of thesocket body 12. An opposite second end portion 44 of thecompression spring 38 is positioned adjacent the openfirst end portion 14 of thesocket body 12. In some embodiments, the second end portion 44 of thecompression spring 38 extends freely and outwardly from theinterior wall 42 and requires no additional stabilization or support. In some embodiments, thecompression spring 38 is provided as an elongated coil spring. However, it is contemplated that various other resiliently deformable spring members could be provided in various shapes and configurations. However, in the embodiments that use an elongated coil spring, the second end portion 44 includes aplug 46 that closes the second end portion 44 of thecompression spring 38. In some embodiments, theplug 46 is placed in a friction-fit engagement with the second end portion 44. In various embodiments, awasher 48 or other planar structure, may be secured with theplug 46 at the distal end of the second end portion 44. In particular embodiments, ascrew 50 or other fastener may be used to secure thewasher 48 with theplug 46. In this arrangement, thecompression spring 38, with its plugged second end portion 44, serves as an engagement member to receive various fasteners and fastener components and bias them toward the openfirst end portion 14. It should be apparent that the force with which such objects are biased will be a function of the strength and resiliency of thecompression spring 38 as well as the proximity with which the second end portion 44 approaches the openfirst end portion 14 of thesocket body 12. Regardless, various fasteners and fastener components may be placed within the open interior portion 16 of thesocket body 12 without becoming lost or misaligned within thesocket body 12. In some embodiments, where portions of the mounting pins 34 extend into the open interior portion 16 of thesocket body 12, the distal end portions of the mounting pins 34 may serve as positive stops to any fasteners or fastener components disposed within the open interior portion 16 of thesocket body 12. In this manner, the fasteners will not be allowed to over travel within the open interior 16. In some embodiments, thefirst end portion 40 of thecompression spring 38 may be secured to theinterior wall 42 of thesocket body 12 through various known mechanical means, such as adhesives, welding, and the use of various fasteners. However, in some embodiments, an opening is formed through theinterior wall 42 such that afastener 52, which may include a screw, bolt, and washer, may be passed through the opening in theinterior wall 42 and extend into a plug 54 that is secured within thefirst end portion 40 of thecompression spring 38. In this manner, thecompression spring 38 is firmly anchored within the interior portion 16 of thesocket body 12. - With reference to
FIGS. 2A-2C andFIGS. 3A-3C , the fastener attachment system of the present technology may at times also be provided with afastener jig 56 that may be used for supporting one or more fasteners in a particular position with respect to a structure so that the fasteners may be secured with that structure. Various embodiments of thefastener jig 56 will include ajig frame 58. At least one pair of opposingfastener jaws jig frame 58. The opposingfastener jaws fastener jaws jig frame 58 between a releasing position, which positions the opposingfastener jaws fastener jaws fastener jaws fasteners 68. In this regard, the opposing engagement faces 64 and 66, when placed closely adjacent one another, may define a single elongated channel. In some embodiments, however, the opposing engagement faces 64 and 66 may define individually shaped channels that closely approximate the size and shape of particular fastener heads. For example, each of the opposing engagement faces 64 and 66 may provide a plurality of individual recesses that are shaped to have a plurality of flat, angularly disposed faces that, when positioned closely adjacent one another, define a hexagonal bolt head recess. In this manner, it is contemplated that the opposing engagement faces 64 and 66 may be provided with nearly any shape to accommodate the head portion of a wide variety ofdifferent fasteners 68. While the aforedescribed engagement faces 64 and 66 have been described as recesses formed within the opposingfastener jaws - With reference to
FIG. 2B , thejig frame 58 may be provided with afastener jaw bolt 70 that is coupled with at least one of the opposingfastener jaws fastener jaw bolt 70 may have a distal end portion that is shaped to rotatably engage thefirst fastener jaw 60 in a manner that allows thefastener jaw bolt 70 to rotate with respect to thefirst fastener jaw 60 while preventing thefirst fastener jaw 60 from advancing or retreating along a length of thefastener jaw bolt 70. In particular embodiments, the distal end portion of thefastener jaw bolt 70 may be disposed within an opening formed in thefirst fastener jaw 60. A pin may be passed through thefirst fastener jaw 60 so that it passes within the opening formed within afirst lug 72 that extends outwardly from thefirst fastener jaw 60 and terminates within a channel formed circumferentially within the distal end portion of thefastener jaw bolt 70. In this manner, thefastener jaw bolt 70 may not be withdrawn from thefirst fastener jaw 60 but may freely rotate therewith. In various embodiments, thefirst lug 72 will extend outwardly from a rearward face of thefirst fastener jaw 60, generally opposite theengagement face 64. - In various embodiments, the
second fastener jaw 62 is provided with asecond lug 74 that extends outwardly from a rearward face of thesecond fastener jaw 62, generally opposite itsengagement face 66. In some embodiments, an opening may be formed through thesecond lug 74 that is shaped to allow thefastener jaw bolt 70 to penetrate thesecond lug 74. In various embodiments, thefastener jaw bolt 70 may be provided with threads that rotatably engage mating threads disposed within the opening in thesecond lug 74. In this manner, rotation of thefastener jaw bolt 70 in a first direction will move the opposingfastener jaws fastener jaw bolts 70 in an opposite second direction will move the opposite pair offastener jaws alignment lug 74 may be provided to extend outwardly from a rearward portion of thejig frame 58. Thealignment lug 74 may have an opening formed through thealignment lug 74 that is sized and shaped to allow thefastener jaw bolt 70 to penetrate thealignment lug 74. In some embodiments, the opening that penetrates thealignment lug 74 will not mechanically engage any structures extending from the fastener jaw bolt 70 (such as mating threads or the like) in a manner that would urge thealignment lug 74 along the length of thefastener jaw bolt 70 in either direction. Accordingly, in some instances, the opening that passes through thealignment lug 74 may simply be provided as a smooth bore. In this manner, thefastener jaw bolt 70 may be securely anchored to and aligned with thejig frame 58. - In order to maintain alignment of the
fastener jaw bolt 70 with respect to the opposingfastener jaws jig frame 58, thefirst lug 72,second lug 74, and thealignment lug 76 may all be provided to extend rearwardly from thejig frame 58. Thefirst lug 72 andsecond lug 74 may be disposed through anopen lug channel 78 that is formed in thejig frame 58. Thealignment lug 76 may be securely coupled with thejig frame 58, adjacent thelug channel 78. In this manner, thefirst lug 72,second lug 74 and thealignment lug 76 are linearly aligned with one another to position thefastener jaw bolt 70 in a manner that permits smooth linear movement of the opposingfastener jaws fastener jaw bolt 70 is rotated. - In various embodiments, the
fastener jig 56 is further provided with a pair of opposing mountingjaws jig frame 58. In various embodiments, at least one of the opposing mountingjaws jaw jaws jaw 80 is secured to a distal end portion of thejig frame 58 and may, in certain embodiments, be formed as an end wall of thejig frame 58 that is fixed in position with respect to thejig frame 58. In such embodiments, the second mountingjaw 82 will be provided to be slidably movable with respect to thejig frame 58. To that end, thefastener jig 56 may be provided with a mountingjaw bolt 84 that is rotatably coupled with thejig frame 58 and the second mountingjaw 82 such that rotation of the mounting jaw bolt in a first direction advances the second mountingjaw 82 toward the securing position while rotating the mountingjaw bolt 84 in a second opposite direction, moves the second mountingjaw 82 toward the releasing position with respect to the first mountingjaw 80. In order to facilitate the movement of the second mountingjaw 82 with respect to the first mountingjaw 80 through rotation of the mountingjaw bolt 84, a distal end portion of the mountingjaw bolt 84 may be rotatably coupled with the second mountingjaw 82. In particular, an opening may be formed within the second mountingjaw 82 through which the distal end portion of the mountingjaw bolt 84 is received. A pin may be passed through the second mountingjaw 82 so that it passes into the opening and is received within a channel that is circumferentially formed in the distal end portion of the mountingjaw bolt 84. In this manner, the mountingjaw bolt 84 may not be withdrawn from within the opening formed in the second mountingjaw 82. However, it may freely rotate therewith without advancing or retreating the second mountingjaw 82 along a length of the mountingjaw bolt 84. In some embodiments, the opening formed through the second mountingjaw 82 is formed through afirst lug 86 that extends from a rearward portion of the second mountingjaw 82. Asecond lug 88 may be provided to extend outwardly from thejig frame 58 in a position that aligns the mountingjaw bolt 84 with thefirst lug 86 of the second mountingjaw 82. Where the mountingjaw bolt 84 is provided as a threaded bolt, mating threads may be formed within the opening that passes through thesecond lug 88 to provide longitudinal movement of the mountingjaw bolt 84 when it is rotated in either direction. In this fashion, rotation of the mounting jaw bolt will advance and retreat the mountingjaw bolt 84 and the second mountingjaw 82 with respect to thejig frame 58 and the first mountingjaw 80. In various embodiments, the opposingfastener jaws jaws fastener jaws - It is contemplated that the
proximal end portions fastener jaw bolt 70 and mountingjaw bolt 84, respectively, may be shaped to engage a working end of a tool or other handle member. For example, theproximal end portions proximal end portions proximal end portions proximal end portions fastener jaw bolts 70 and the mountingjaw bolts 84 may be provided with an articulating joint 94 that permits the associated proximal end of the bolt to extend away from the adjacent bolt for ease of engagement and manipulation of the same. - With reference to
FIGS. 3A-3C , some embodiments of the fastener attachment system will be provided with multiple pairs of opposing fastener jaws. In some embodiments, a second pair of opposing fastener jaws are coupled with thejig frame 58, between the first mountingjaw 80 and thesecond fastener jaw 62. Specifically, athird fastener jaw 96 is positioned adjacent thesecond fastener jaw 62. Afourth fastener jaw 98 is positioned adjacent thethird fastener jaw 96. Thethird fastener jaw 96 andfourth fastener jaw 98, in various embodiments, will be provided with a similar design and function to those of thefirst fastener jaw 60 andsecond fastener jaw 62. In particular, thethird fastener jaw 96 andfourth fastener jaw 98 are provided with anengagement face 100 andengagement face 102, respectively. The opposing engagement faces 100 and 102 may be shaped and oriented, with respect to thethird fastener jaw 96 andfourth fastener jaw 98, in a manner similar to that described previously with respect to the engagement faces 64 and 66. Athird lug 104 may be provided to extend rearwardly from thethird fastener jaw 96 and afourth lug 106 may be provided to extend rearwardly from thefourth fastener jaw 98. Thethird lug 104 andfourth lug 106 may further be positioned to extend through thelug channel 78 formed within thejig frame 58. In various embodiments, thefourth lug 106 is provided with mating threads that engage threads along an exterior surface of thefastener jaw bolt 70 such that rotation of thefastener jaw bolt 70 in opposite directions will advance and retreat thefourth fastener jaw 98 along a length of thefastener jaw bolt 70. An opening penetrating thethird lug 104 may be provided with a smooth diameter that exceeds the outer diameter of thefastener jaw bolt 70 so that thethird fastener jaw 96 does not advance or retreat along a length of thefastener jaw bolt 70 when the same is rotated in either direction. - In various embodiments, the
first fastener jaw 60,second fastener jaw 62,third fastener jaw 96 andfourth fastener jaw 98 may each be coupled with afirst guide rail 108 and opposingsecond guide rail 110. In some embodiments,first end portions 112 and 114 of thefirst guide rail 108 andsecond guide rail 110 may be securely anchored within side portions of thefirst fastener jaw 60. Similarly, asecond end portion 116 andsecond end portion 118 of thefirst guide rail 108 andsecond guide rail 110, respectively, may be firmly secured within opposite side portions of thefourth fastener jaw 98. In these orientations, thefirst fastener jaw 60 andfourth fastener jaw 98 may be anchored in position with respect to one another and thefastener jig 56. Openings that penetrate the side portions of thesecond fastener jaw 62 andthird fastener jaw 96 may be provided with a diameter greater than an outer diameter of thefirst guide rail 108 andsecond guide rail 110 such that thesecond fastener jaw 62 andthird fastener jaw 96 may continue to advance and retreat along the length of thefastener jaw bolt 70 as it is rotated in each of its opposite directions. This arrangement provides uniform, simultaneous movement of the two fastener jaw assemblies with respect to one another. Alternate embodiments of thefastener jig 56 may simply provide sets of tabs that extend outwardly from the side portions of each of thefastener jaws 82 and are placed within side channels formed through the side portions of thejig frame 58. In such arrangements, one or more of the tabs could be anchored in a particular location with respect to thejig frame 58 to prevent movement of the same as its counterpart fastener jaw is advanced or retreated along the length of thefastener jaw bolt 70. - It is contemplated that various uses of the fastener attachment system may require additional tools to apply, remove, or otherwise engage fasteners associated with one or more structures. Accordingly, it is contemplated that a plurality of accessories may be designed to be at least partially received within the open interior portion 16 of the
socket assembly 10 when thesocket assembly 10 is coupled with a tool, such as a hot-stick, socket wrench, or the like. With reference toFIGS. 4A and 4B , acotter pin extractor 120 may be provided with afirst end portion 122 that is specifically shaped for secure engagement within the open interior portion 16 of thesocket body 12. Alocking button 124 may be provided to extend outwardly from thecotter pin extractor 120 and be received within a receivingaperture 126 formed through thesocket body 12. An elongated pin may be used to pass through the receivingaperture 126, through thesocket body 12, and depress thelocking button 124 when removal of thecotter pin extractor 120 from thesocket body 12 is desired. Asecond end portion 128 of thecotter pin extractor 120 may be provided with a hook shape familiar to those in the art as being used for the removal of cotter pins. Similar accessories can be provided, such as the screwdriver attachments depicted inFIGS. 4C and 4D . With reference toFIG. 4C , a blade-style screwdriver 130 may be provided with afirst end portion 132 that is shaped to be received within thesocket body 12. An opposite,second end portion 134 may be provided with a shape commonly indicative of bladed screwdrivers. With reference toFIG. 4D , aPhillips screwdriver attachment 136 may be provided with afirst end portion 138 that is also shaped to be received within thesocket body 12 but is provided with asecond end portion 140 that includes a Phillips style head known in the art. It should be clear that the versatility of the design of the fastener attachment system of the present technology will permit the use of a vast array of accessories that may be associated with thesocket assembly 10. In particular, the accessory attachments may be provided with nearly any fastener engagement shapes, common to tools used by most workmen. - Several methods of use for the fastener attachment system are contemplated for engaging and securing or removing fasteners of a wide variety from an array of structures. For exemplary purposes only, an embodiment of the fastener attachment system will be described as the same could be used by workman users who seek to secure a jumper connector pad with a switch terminal connector pad with a plurality of fasteners. With reference to
FIG. 5 , a plurality offasteners 68 are positioned between thefirst fastener jaw 60 andsecond fastener jaw 62. Similarly, a pair offasteners 68 are disposed between thethird fastener jaw 96 and thefourth fastener jaw 98. In particular applications, afastener alignment jig 142 may be provided to ensure that the spacing between thefasteners 68 and their orientation is appropriate for the structure to which thefastener 68 will be secured. In various embodiments, thefastener alignment jig 142 is simply a plate member having a plurality of apertures that penetrate the plate member at the appropriate orientation with respect to one another. Once the plurality offasteners 68 have been aligned within the first and second pairs of fastener jaws, thefastener jaw bolt 70 may be rotated to ensure that thefasteners 68 are secure in their position. The user may then couple the mountingjaw bolt 84 with a working end of a tool, such as the hooked end portion of a hot-stick 144. The user may then extend the hot-stick 144 and thefastener jig 56 toward a first structure, such as a conductor dead-end connector pad 146, which is designed to receive thefasteners 68. Thefasteners 68 are guided through openings that penetrate the conductor dead-end connector pad 146. Once a portion of the side edges of the switch terminal connector pad are positioned between the first mountingjaw 80 and second mountingjaw 82, the mountingjaw bolt 84 is rotated using the hot-stick until the first mountingjaw 80 and second mountingjaw 82 are in a secure position with respect to the edges of the conductor dead-end connector pad 146.FIG. 7 depicts an exemplary manner in which the structures will appear after performing these steps. - With reference to
FIG. 8 , a workman user may use a tool to grab the distal end of ajumper connector pad 148 with another tool, such as a second lineman's hot-stick 144. The workman then manipulates thejumper connector pad 148 until the length of thefasteners 68 are passed through pairs of openings that penetrate thejumper connector pad 148. The first workman user may remove his hot-stick from the mountingjaw bolt 84 and secure the hot-stick 144 to thesecond end portion 18 of thesocket assembly 10. Fastener components such as anut 150,flat washer 152, and lockwasher 154 may then be passed between the plurality of retainingblades 24 so that they are disposed within the open interior portion 16 of thesocket body 12. Theblade retaining ring 22 is then withdrawn away from theblade guide 32, which compresses the retainingblades 24 toward one another and secures thenut 150 andwashers 154 andflat washer 152 within thesocket body 12. In this position, the fastener components have partially compressed thecompression spring 38, which biases the fastener components outwardly from the openfirst end portion 14 of thesocket body 12. However, thetips 30 of theretaining blades 24 retain the fastener components within thesocket body 12. The plurality of retainingblades 24 further align the fastener components with one another, preventing the need for the use of a separate alignment tool for the propensity for the fastener components to become misaligned during application. The workman user may then extend the hot-stick 144 toward a distal end portion of afastener 68 and place the fastener components onto the distal end of thefastener 68. Rotation of the hot-stick 144 will thread thenut 150 onto the distal end of thefastener 68 and loosely secure the fastener components with thefastener 68. The workman user may then simply pull the hot-stick 144 and thesocket assembly 10 free from the fastener component by pulling thesocket assembly 10 from the fastener components will move theblade retaining ring 22 towards theblade retaining guide 32 allowing the retainingblades 24 to slide through theblade retaining guide 32 moving the retainingblade tips 30 outwardly from the openfirst end portion 14 of thesocket body 12, the retainingblades 24 are resiliently deformable and will bias outwardly as the hot-stick 144 andsocket assembly 10 are withdrawn from thefastener 68 and fastener components. This procedure is repeated until each of thefastener components 68 extending from the conductor dead-end connector pad 146 andjumper connector pad 148 have a series of fastener components loosely secured thereto. The workman user may then simply exchange thesocket assembly 10 at the end of the hot-stick 144 with a standard socket which is then used to tightly secure each of thenuts 150 with thefasteners 68. In this manner, the switchterminal connector pad 146 and thejumper connector pad 148 are secure with one another. Disassembly of the fasteners to separate the structures from one another may be accomplished by simply reversing the assembly process. In this process, thesocket assembly 10 may be used to grasp each of the fastener components so that they do not simply fall to the ground, such as has been the practice in the past. - Although the technology has been described in language that is specific to certain structures, materials, and methodological steps, it is to be understood that the invention defined in the appended claims is not necessarily limited to the specific structures, materials, and/or steps described.
