ABSTRACT:
A fixed support member includes upper and lower horizontal plates, and a movable support member is coupled to the fixed support member for vertical movement. A drive screw extending between the fixed support member upper and lower horizontal plates and coupled to the movable support member for adjusting the position of the movable support member relative to the fixed support member by rotation of the drive screw. A locking plate fixed to a lower surface of the fixed support member lower horizontal plate having an opening receiving a lower end of the drive screw. A drive coupling connected to the lower end of the drive screw has a portion that can be coupled to a torque input device so that a torque applied to the drive coupling can cause rotation of the drive screw. The drive coupling has an upper portion shaped to be received in the locking plate opening to prevent rotation of the drive coupling and drive screw. A spring coupled between the drive coupling and the drive screw biases the drive coupling toward engagement with the locking plate opening.
