in the summary above and in this detailed description , and the claims below , and in the accompanying drawings , reference is made to particular features ( including method steps ) of the invention . it is to be understood that the disclosure of the invention in this specification includes all possible combinations of such particular features . for example , where a particular feature is disclosed in the context of a particular aspect or embodiment of the invention , or a particular claim , that feature can also be used , to the extent possible , in combination with and / or in the context of other particular aspects and embodiments of the invention , and in the invention generally . the term “ comprises ” and grammatical equivalents thereof are used herein to mean that other components , ingredients , steps , among others , are optionally present . for example , an article “ comprising ” ( or “ which comprises ”) components a , b and c can consist of ( i . e ., contain only ) components a , b and c , or can contain not only components a , b , and c but also contain one or more other components . where reference is made herein to a method comprising two or more defined steps , the defined steps can be carried out in any order or simultaneously ( except where the context excludes that possibility ), and the method can include one or more other steps which are carried out before any of the defined steps , between two of the defined steps , or after all the defined steps ( except where the context excludes that possibility ). the term “ at least ” followed by a number is used herein to denote the start of a range beginning with that number ( which may be a range having an upper limit or no upper limit , depending on the variable being defined ). for example , “ at least 1 ” means 1 or more than 1 . the term “ at most ” followed by a number ( which may be a range having 1 or 0 as its lower limit , or a range having no lower limit , depending upon the variable being defined ). for example , “ at most 4 ” means 4 or less than 4 , and “ at most 40 %” means 40 % or less than 40 %. when , in this specification , a range is given as “( a first number ) to ( a second number )” or “( a first number )-( a second number ),” this means a range whose limit is the second number . for example , 25 to 100 mm means a range whose lower limit is 25 mm and upper limit is 100 mm the preferred embodiment utilizes a reflective pinwheel , featuring a red or silver holographic color . the pinwheel may be connected to an overhead power distribution transformer bushing or to a fuse cut - out using an industry standard hex standoff bolt with threaded ends . the bolt may be positioned directly onto the top of the bushing , onto the fuse cutout or onto other strategic positions . the invention takes advantage of the alternating colors of the pinwheel to scare the birds , and requires no housing , rotors , drums , or support plates . additionally , the invention does not rely on sound and it requires no electricity or motor . the pinwheel itself is preferably made from recyclable or recycled material such as nylon , plastics , and metals including aluminum . the pinwheel also has a plurality of fins in the shape of loops , each with front and back faces with a holographic orchard - style reflective surface attached with contrasting colors such as red with white . the reflective surfaces are attached in alternating color sequence to the front and back faces of each fin such that each adjacent fin will be alternate , for example , red or silver holographic colors . the fins are formed around a metallic - reinforced ring and fan out in substantially the same way as the fins of a windmill . the center ring fits around the unthreaded collar section of a bolt ( which is itself inserted into a hex bolt ), which screws into the female threaded end of a male female hex coupling nut , which is attached to the top of a bushing . the pinwheel , therefore , freely spins around an axis in line with , for example , the unthreaded collar section of the bolt . the bolt and its hex head are fixed to a distribution transformer bushing or to a fuse cut - out . an alternative embodiment features a pinwheel made from non - recyclable material including fiberglass , carbon fiber , metals , and certain plastics including polyethylene and polyvinyl chloride ( pvc ). a second alternative embodiment features a coupling system that allows the present invention to be attached to different surfaces , buildings , and objects including street lights , eves of buildings , rooftops , traffic lights , traffic light posts , bridges , archways , fences , gates , farms , trees , bushes , swimming pools , and other surfaces . the pinwheel with this coupling system may be installed by hooks , clamps , screws , nails , adhesive material , and other coupling means common in the art . a third alternative embodiment features non red and white alternating contrasting holographic color pairings such as black and silver or orange and blue . a fourth alternative embodiment features additional friction - resistant parts such as bushings , washers , and grommets . the friction - resistance can be achieved from materials such as silicone or through coatings such as teflon ( a trademark of the chemours company fc , llc ). a fifth alternative embodiment features a pinwheel with fins formed from actual loops rather than fins with solid front and back faces or surfaces . these skeletonized loop fins will maintain the same shape as the fins in the preferred embodiment but use less material . the reflective surfaces can still be attached along the surface of the loops and achieve the same effect . fig1 is an angular perspective view of the invention showing the partially threaded connector bolt 4 connected to the hexagonal ( hex ) coupling nut 1 . in this view , the threaded internal center 7 is visible along with the non - threaded collar end 3 with raised collar 2 that forms a terminal barrier to prevent an attached or fitted pinwheel from sliding off . the pinwheel will freely spin on the corresponding axis formed by the partially threaded connector bolt depending on the angular orientation of the bolt . for example , if the bolt is tilted to a completely non - upright , horizontal position , the pinwheel would spin about the x - axis . fig2 is a side cross - sectional view of the invention and shows different components and how they are connected . first , the connector bolt is passed through the center of the pinwheel 6 until the bolt &# 39 ; s raised collar 2 meets the pinwheel and the non - threaded portion of the bolt is fit within the center of the pinwheel with minimal clearance . the minimal clearance allows the pinwheel to freely rotate or spin about the non - threaded portion and stay in place due to the collar or raised end of the connector bolt that forms a terminal barrier . the threaded portion of the connector bolt is then screwed into the hexagonal coupling nut 1 . fig3 is a side view of the invention featuring the pinwheel 6 sitting between the collar 2 of the connector bolt and the hexagonal coupling nut 1 . this view provides a different perspective from fig2 . fig4 shows a top view 11 of the invention mounted on top of a primary bushing 10 of a fuse cutout found on power pole assemblies . there is also a is a side view 12 which shows the hexagonal coupling nut connected 1 to the top of the top of the primary bushing 10 by a separate threaded connector bolt 13 . the pinwheel is still located on the non - threaded collar end of the partially threaded connector bolt 4 and can free spin around the non - threaded end via wind . fig5 is a front view of the pinwheel showing a plurality of fins 8 with the metallic reinforced ring 9 . the pinwheel &# 39 ; s fins are loops that fan out as blades like those of a windmill , and said fins are angled in a uniform direction to allow rotational movement in both clockwise and counter - clockwise directions , depending on the direction of the wind . the fins 8 are joined together at the center where the metallic reinforced ring 9 is located . fig6 is a side perspective view of the hexagonal coupling nut . the nut a hollow , threaded core to receive the threaded portion of a reciprocal connector bolt at either end , such as the partially threaded connector bolt mentioned above . the nut has flat sides 14 at both ends because the nut is symmetrical . when the nut and the pinwheel are both connected to the partially threaded connector bolt in the proper configuration , the pinwheel will be wedged between the collar of the partially threaded connector bolt and the flat side 14 of one end of the hexagonal coupling nut with minimum clearance . this , along with the non - threaded surface of the non - threaded side of the partially threaded connector bolt will allow the pinwheel to freely spin in place . fig7 is a side view of the partially threaded connector bolt 4 . the bolt has a threaded end 5 and a non - threaded collar end 3 that has a collar or raised lip 2 that acts as a terminal barrier . the collar makes contact with the side walls of the metallic reinforced center ring at the center of the pinwheel when the partially threaded connector bolt is passed through the pinwheel . fig8 is a side landscape view of a power line or utility pole system . fig8 diagrams this system to show the location of a primary bushing that the present invention would be mounted on . while preferred and alternate embodiments have been illustrated and described , as noted above , many changes can be made without departing from the spirit and scope of this device for powerline preservation . accordingly , the scope of the device for powerline preservation is not limited by the disclosure of these preferred and alternate embodiments . instead , the scope of the device for powerline preservation is to be determined entirely by reference to the claims . insofar as the description above and the accompanying drawings ( if any ) disclose any additional subject matter that is not within the scope of the claims below , the inventions are not dedicated to the public and applicant hereby reserves the right to file one or more applications to claim such additional inventions . the reader &# 39 ; s attention is directed to all papers and documents which are filed concurrently with this specification and which are open to public inspection with this specification , and the contents of all such papers and documents are incorporated herein by reference . all the features disclosed in this specification ( including any accompanying claims , abstract , and drawings ) may be replaced by alternative features serving the same , equivalent or similar purpose , unless expressly stated otherwise . thus , unless expressly stated otherwise , each feature disclosed is one example of a generic series of equivalent or similar features . any element in a claim that does not explicitly state “ means for ” performing a specified function , or “ step for ” performing a specific function is not to be interpreted as a “ means ” or “ step ” clause as specified in 35 . u . s . c . § 112 ¶ 6 . in particular , the use of “ step of ” in the claims herein is not intended to invoke the provisions of u . s . c . § 112 ¶ 6 .
