Screw Action Leveling Device

This device utilizes a left and right-hand screw thread to provide double action to raise and/or lower a machine unit. It provides a means of leveling and converting a machine unit from a mobile to a stationary unit.

This assembly when properly mounted on the machine frame will allow the machine base to sit on or near the floor, thus eliminating the need for kickplates which are conventionally used on today's computer units.

This device improves the means of leveling the machine during installation and servicing. It can be adjusted from above the machine base whereas the older design required personnel to work under the machine base to level the unit, creating a serious safety hazard to remove and replace a damaged caster.

Mounting the caster on a double-acting screw eliminates the need for leveling pads and kickplates. Since it allows placement of the machine closer to the floor, it will also lower the height appearance.

The bracket 10 containing the screw piece 12 is attached to the frame 14. Turning the nut 16 located on top of the screw unit 12 gives the up and down adjustment. The pad or roller 18 screws into the screw unit 12 and is opposite threaded so as to raise or lower the roller 18, depending on which direction the screw unit 12 is turned.
