Abstract: Apparatus and method are provided for indicating when a predetermined amount of tension has been applied to a band by a banding tool. The apparatus includes a housing, a lever for transferring pressure, and a tension indicator. As a tool handle is rotated to apply tension to a band, pressure is applied to the lever. When the tension applied is substantially equal to the predetermined tension, the lever pivots and activates the indicator, indicating to the operator of the banding tool that sufficient tension has been applied. In one embodiment, the indicator extends into the path of the rotating tool handle, thus preventing the operator from applying further tension to the band.

Abstract: A self-adjusting selector dial shift indicator mechanism is disclosed for an automatic transmission control system. The system includes a carriage assembly having a carrier member and an indicator member slidably interlocked by resilient biasing means for joint longitudinal movement on a support housing. A pair of stops on the housing limit the reciprocal travel of the indicator member at opposite end positions wherein its pointer is aligned respectively with the dial low-drive and park indicia. A first cable section connects the carrier member to the housing. A second cable section connects the carrier to the shift lever steering column tube. Movement of the shift lever from low-drive to park overcomes the biasing means allowing the carrier member to slip relative to the indicator member at each end of the dial automatically indexing its pointer wherein manual adjustment of the cable section is eliminated.

Abstract: The knotting mechanism of a crop baler has a spring-loaded arm normally pulled down to a lowered position by the binding twine during operation of the knotter. However, if the knotter accidentally fails to tie a knot or the twine otherwise slips loose, the resulting slack will allow the arm to swing upwardly, and this motion may be used to trigger a switch for setting off an alarm or to raise a signal flag, either of which would indicate that the knotter needs attention.
