Patent ID: 7607631

Claim:
An automatic frame leveler, comprising: a. a frame support having at least a first side and a second side; b. a first pivotable bob pivotably attached to said frame support by a first support pivot, and a second pivotable bob pivotably attached to said frame support by a second support pivot, each of said first and second bobs comprised of an elongated bob member having a first end and a second end, said first end attached to the support pivot, and said second end attached to a weight, wherein said support pivot is freely moveable to align the elongated bob member longitudinally parallel to the direction of gravity; c. a first spring attached to the first bob and a second spring attached the second bob, said first spring attached to a first locking member, said first locking member in operative association with a first take-up reel, said first take-up reel attached to the frame support and having toothed gears for interacting with said first locking member to provide a first pawl and ratchet mechanism, said second spring attached to a second locking member, said second locking member in operative association with a second take-up reel, said second take-up reel attached to the frame support and having toothed gears for interacting with said second locking member to provide a second pawl and ratchet mechanism; d. an extensible cable having a first end and a second end, said first end mounted on said first take-up reel, said cable threaded through one or more cable guides attached to the frame support, and said second end mounted on said second take-up reel; wherein when the first side of the frame support is tilted higher than the second side, the first pivotable bob will temporarily disengage from the first take-up reel by swinging away from the first take-up reel and removing the first locking member from the toothed gears of the first take-up reel, upon disengagement of the first locking member the take-up reel will wind a length of the cable pulling the first pivotable bob back into proximity with the first take-up reel at which time the first spring will reengage the first locking member into the toothed gears of the first take-up reel, and wherein when the second side is tilted higher, the same mechanism reestablishes proper alignment from the second bob and reel action, wherein the frame leveler maintains a level orientation without requiring the intervention of a person to readjust the frame to a level position.
