Abstract

A device for indicating tension of a cable 10 comprises a base bar 11 and a detent bar 12 pivotally mounted thereon at pivot 13. A pair of spaced dowel pins 14 and 15 protrude from the side of base bar 11 below detent bar 12 which has a detent 16 on the bottom edge thereof located between the dowel pins. A latching mechanism for holding detent bar 12 in closed position for predetermined tension levels of cable 10, as shown in solid lines in the Figures comprises a plunger screw 17 threaded into the end of base bar 11 with a ball 18 set in the end of screw 17 for frictionally engaging latch cup 19 on the free end of detent bar 12. The pressure between ball 18 and latch cup 19 is adjustable by rotation of screw 17.

Cable Tension Indicator

A device for indicating tension of a cable 10 comprises a base bar 11 and a detent bar 12 pivotally mounted thereon at pivot 13. A pair of spaced dowel pins 14 and 15 protrude from the side of base bar 11 below detent bar 12 which has a detent 16 on the bottom edge thereof located between the dowel pins. A latching mechanism for holding detent bar 12 in closed position for predetermined tension levels of cable 10, as shown in solid lines in the Figures comprises a plunger screw 17 threaded into the end of base bar 11 with a ball 18 set in the end of screw 17 for frictionally engaging latch cup 19 on the free end of detent bar 12. The pressure between ball 18 and latch cup 19 is adjustable by rotation of screw
17. Calibration marks 20 in the end of base bar 11 adjacent the screw 17 provide high and low tension settings for measuring the tension of cable 10.

The tension of cable 10 is adjusted by lifting detent bar 12 to tension settings for measuring the tension of cable 10.

The tension of cable 10 is adjusted by lifting detent bar 12 to the dotted line position of Figure A and passing cable 10 over dowel pins 14 and 15. Detent bar 12 is then lowered to the solid line position where it is latched closed by ball 18 and cup 19 with detent 16 causing a bend of cable 10 between the dowel pins 14 and 15. With plunger screw 17 set to the high calibration mark 20, the indicator is closed if the tension of cable 10 is below the predetermined high l...
