Definitions

  • each wire is pivoted to the spacer damper body with a relatively delicate current conducting sleeve in the pivot axis in addition to one or more torsion devices resisting pivotal movement.
  • Limit means for limiting pivotal movement prevent the application of radial compressive forces to said sleeve.
  • This invention relates to a spacer damper of the type used DESCRIPTION OF PRIOR ART
  • spacer damper of the type used DESCRIPTION OF PRIOR ART
  • Devices of the particular class are utilized for holding a series of power transmitting wires, generally four, in spaced relation to one another, provisions being made so that each of the wires may move relatively to the spacer damper body, with its movement being damped by the spacer body, possibly aided by the other three wire conductors.
  • each wire conductor In spacer dampers of the particular class, it is customary to secure each wire conductor to an arm, with the arm in turn being pivoted to the spacer damper body. Pivotal movement of the arm is generally resisted by a torsion disk, and there may frequently be two torsion disks. These disks interlock the arm and the body, so that there can be no movement of the arm relatively to the body except through torsional twisting of the disks.
  • a conducting sleeve of some suitable material such as rubber.
  • the torsion disks to which reference has been made may be used for this purpose, through embedding carbon black in the plastic material of the torsion disks.
  • the torsion disks when impregnated with carbon black, lose their resiliency, and deteriorate with great speed. Therefore, a separate small current carrying sleeve has been developed for the particular purpose and is, as was indicated above, mounted about the pivot shaft.
  • means are provided for preventing the application of destructive forces, generally compressive, to the rubber sleeve, while also limiting the torsional twisting of the disks.
  • the invention resides in the utilization of balanced limiting means that serve the purpose of limiting rotation of each conductor carrying arm relatively to the spacer damper body, while at the same time, preventing the application of compressive destructive forces to the rubber sleeve.
  • FIG. 1 is a view in isometric showing a typical installation of long distance transmission conductor wires held in spaced relation by a series of spacer dampers utilizing the construction of this invention.
  • FIG. 2 is an elevation of one of the spacer dampers shown in FIG. 1.
  • FIG. 3 is a section taken along line 3--3 of FIG. 2.
  • FIG. 4 is an enlarged elevation of one of the extensions of the spacer damper shown in FIG. 2 illustrating portions of the invention.
  • FIG. 5 is a section taken along line 55 of FIG. 4.
  • FIG. 6 is a section taken along line 6-6 of FIG. 5.
  • FIG. 7 is a view in isometric showing a torsion disk that is utilized in the invention.
  • FIG. 8 is a composite view showing parts of FIGS. 4 and 6 with the transmission wire and its arm rotated to a stop position relatively to the spacer damper body.
  • FIG. 1 there are shown four transmission wires designated by reference numerals 10, I1, 12 and 13, each adapted to be controlled in its vibrating and swinging movement by a series of spacer dampers designated by reference numerals 14.
  • the wires are shown held in an elevated supported position by a standard type of support 15 that is in turn held in position by a tower 16 as is standard in the art.
  • Each of the wires 10, 11, 12, I3 is secured to each spacer damper body 14 through means of a clamping mechanism 20 that is in turn pivoted to the spacer damper body about an axis designated 21, this being the longitudinal axis of a bolt 22 best illustrated in turn in FIG. 5.
  • the spacer damper body 14 used may assume various forms, but the form here illustrated is fabricated from two plates designated by reference numerals 25 and 26 in FIG. 3, the plates being there shown separated by a sleeve 27 and held assembled by a bolt 28 and a nut 29. Preferably there will be two of the bolts 28 as well shown in FIG. 2.
  • the spacer damper plates 25 and 26 are further held assembled to one another through the intermediary of the four bolts 22, one of which has been referred to and is well shown in FIG. 5.
  • the functioning of one of the bolts 22 will now be described, it being appreciated, that all of the bolts 22 function in exactly the same manner for mounting the several clamps 20.
  • the bolt 22 traverses an opening 30 in the part 25 of the spacer damper body 14.
  • the bolt also traverses an opening 31 in the part 26 of the spacer damper body 14. It also traverses openings in two opposed torsion disks 32, one of the disks being well illustrated in FIG. 7.
  • Each torsion disk 32 is fonned with upstanding ribs 33 at each face thereof, and each of the parts 25 and 26, has a series of depressions 34 into which the ribs 33 are adapted to enter in order to lock each of the disks against rotation relatively to the parts 25 and 26.
  • the plates 25 and 26 are each formed with a circular flange 40 outlining a circular depression into which the disks 32 are adapted to fit and to be housed.
  • the clamp 20 into which the transmission wire 10 is adapted to fit as well shown in the several figures, is typical of each of the clamps utilized in the invention. It has extending therefrom an arm 41 through which it is mounted about the bolt 22, and for the purpose of mounting the arm 41 about the axis 21 of the bolt 22, the arm is formed with a relatively large opening 42 into which is adapted to fit a rubber sleeve 44, the rubber sleeve in turn being formed with an opening that allows it to fit closely about the bolt 22 and to lie between the bolt 22 and the arm 41. This is all well illustrated in FIG. 5.
  • the arm is also formed with a series of depressions 45 at each side thereof, these depressions being exactly the same form as the depressions 34 in the parts 25 and 26.
  • depressions 45 The purpose of the depressions 45 is to house the ribs 33 of the faces of the two disks 32 lying against the opposed surfaces of arm 41, so as to lock the arm 41 against rotation relatively to the parts 25 and 26 of the spacer damper except through the torsional twisting of the two disks 32.
  • the rubber sleeve 44 is utilized, this sleeve being suitably impregnated with sufficient carbon black to render it conductive.
  • the sleeve is rendered relatively weak and easily damaged by extreme deflection.
  • the invention provides means for not only limiting the rotation of the arm 41 relatively to the spacer damper so as to protect the disks 32, but also for preventing the transmission of compressive stresses to the sleeve 44.
  • each of the parts 25 and 26 is formed with a pair of generally circular segmental lugs 50 and 51 best illustrated in FIG.-6, but well shown also in FIGS. 4, 5 and 8.
  • the arm 41 is fonned with an extension 52 as shown in FIGS. 4, 5 and 8.
  • FIG. 8 rotation of the clamp '20 and the arm 41 about axis 21 of bolt 22 is well illustrated. This is the rotation that will take place upon relatively forceful movement of the conductor wire 10 and its clamp 20 against the resistance of the two torsion disks 32.
  • a portion of the arm 41 designated particularly by the reference numeral 4la has contacted the part 50:10! the lug 50.
  • the part 52a of the extension 52 of arm 41 has contacted the surface 51a of the lug 51.
  • a spacer ,damper In a spacer ,damper; a spacer body member; an arm member for supporting a conductor; a pivot shaft extending through aligned openings in said members; a conducting sleeve fitted into an opening in one of said members and also on said shaft providing a path for the flow of electricity between said members through said shaft; torsion means yieldingly holding said body member and said arm member against relative rotation on the axis of said shaft; said body member and said arm member including first interacting limit means and second interacting limit means angularly spaced apart relative to said pivot shaft; each of said limit means resisting forces tending to rotate said arm about the other of said limit means relative to said body member, and preventing such forces from moving said arm in a direction generally radial to said shaft, whereby radial compression of said conducting sleeve against said shaftis precluded.
  • each of said first and said second interacting limit means comprises a generally radial shoulder on said arm member and a mating abutment on said body member positioned to engage the said radial shoulder following a given angular displacement of said arm member about said pivot shaft.
  • first and said second interacting limit means together include a pair of generally radial projections on said arm member and a pair of cooperating projections on said body member positioned so that one projection on said arm member will alternately engage one or the other of the projections on the said body member upon rotation of said arm member in different directions about said shaft, and the other of said projections on said arm member correspondingly will engage the remaining one of said projections on said body member.
