Hanging cable shortener arrangement
View Patent ↗A cable shortener apparatus for permitting the length adjustment of a cable having a certain incompressable diameter. The cable is arranged for supporting a sign carrier from an overhead support. The cable shortener apparatus may be comprised of a duplicate pair of generally rigid annular rings lockably engagable with one another. Each ring may have an inner arcuate hub flange which defines a fixed hub surface for receiving at least one wrap of a support cable. An annular edge on each of the rings is spaced apart from one another when the rings are mated together. The spaced apart annular edges defining a gap no wider than the diameter of the cable being wrapped about the hub of the shortener.
1. A method of adjusting a non-compressible sign supporting cable holding a sign carrier from an overhead support, said cable having a certain diameter, said method comprising:
attaching an upper end of said non-compressible cable to said overhead support;
attaching a lower end of said non-compressible cable to said sign;
forming an annular hub with a first end and a second end;
arranging a generally rigid, radially outwardly extending flange on each end of said hub, each of said radially outwardly extending flanges having an outer peripheral yieldable lip spaced apart from said outer peripheral lip of the other of said flanges by a distance less than twice said certain cable diameter;
wrapping or unwrapping an entering or upper end of said cable about said hub and extending an exiting or lower end of said cable exiting from said hub between said radially outwardly extending flange, said entering end and said exiting end of said cable being 180 degrees out of phase with one another as in a straight line so as to permit the simple adjustment of the length of said cable supporting said sign carrier.
2. The method as recited in claim 1 , including:
forming said hub and radially outwardly extending flanges by mating together a pair of rigid annular rings, each of said rings having an arcuate hub portion and a generally rigid annular edge defining an inner and an outer wall member of each of said rings;
spacing said rigid annular edges with said yieldable lips thereon apart by less than twice said certain diameter of said cable;
wrapping said cable about said hub portion of said annular rings to change the length of said cable supporting said sign carrier.
3. The method as recited in claim 2 , including:
forming an arcuate inner locking flange on each of said rings to permit said rings to lock onto one another.
4. The method as recited in claim 1 , including:
spacing said inner locking flange on one of said rigid annular rings radially adjacent said arcuate hub flange of the other of said rigid annular rings when said rigid annular rings are mated together.
