Abstract:
An assembly for monitoring the travel of a device, comprising:a potentiometer having a moveable member, said potentiometer generating a resistance value according to a position of said moveable member;a bracket coupled to said potentiometer;a threaded rotatable member carried by said bracket, said rotatable member having a threaded shaft and adapted to be coupled to the device; anda slide rack carried by said bracket, said slide rack coupled to said moveable member and said threaded rotatable member, said slide rack operatively engaged with said tbreaded, rotatable member between predetermined first and second positions and operatively disengaged from said rotatable member at said first and second positions, wherein said slide rack includes a block having an opening defining a tongue and being only linearly slidable on said bracket, said block having a threaded deflectable member, said threaded deflectable member having a section of threads on said tongue fully meshing with said rotatable threaded member between said first and second positions such that said moveable member is moved between said first and second positions, wherein at said first and second positions rotation of said threaded shaft forces deflection of said threaded deflectable member and disengagement of said section of threads from said threaded shaft to preclude linear movement of said block.
