ABSTRACT:
This disclosure pertains to a line tensioning device adapted to automatically tension a line fastened to an arm. The arm alternately engages outwardly spring biased rows of cams disposed on an upper and lowermost edge of a beam member which inturn is secured at one free end to a supporting structure. The upper row of cams are disposed in spaced apart relationship to the lower row of cams. As the line decreases the tensioning forces on the arm, the arm changes its angular relationship with the axis of the beam member permitting the arm to engage cams more closely located to the supported end of the beam member, maintaining the tensioning forces in the line thereby.
