Abstract
A leveling device is disclosed herein for automatically maintaining an absorption refrigerator and freezing unit in a level orientation which includes a ball and socket joint for pivotally mounting the unit to a fixed wall for movement about a horizontal axis. Ducts passing through the ball and socket joint interconnect freezer unit with absorption unit. A solenoid operated leveling device automatically positions the unit to a level position in response to solenoid push rods. A mercury liquid cell carried on the refrigerator unit having quadrant segments operably connects with the solenoids for selectively actuating the push rods when the liquid level changes. The ball and socket joint permits the freezer and absorption unit to automatically level itself by the gravitational pull of the earth assisted by a solenoid operated leveling device that helps position the freezer and absorption unit to a level position. A unit hold down and movable support assembly may be employed when the unit is not cantilevered from its ball and socket joint so that adjustment can be manually achieved.
