| 20120261629 | VERTICAL LIFT MECHANISM FOR USE IN CONFINED SPACES - A compact lift apparatus for use in confined spaces to raise and lower an object is described. The apparatus includes first and second drag chains with upper object mourning ends that are moveable along paths having adjacent vertical inner sections with lower ends and chain storage sections extending outwardly from the lower ends of the lower sections, the chain storage sections extending outwardly in opposite directions; spaced parallel plates on opposite sides of the chains, the plates including inner faces that together define drag chain raceways forming the paths; and drive means simultaneously conveying the drag chains along the paths between the lowered and raised positions to raise and lower the mounting ends, the drive means including first and second rotatable sprockets having teeth engaging the chain lengths and a drive means to rotate at least one of the sprockets. | 10-18-2012 |
| 20130043447 | CHAIN STOPPER FOR CHAIN PULLER - A chain puller for use in marine salvage that includes a chain pulling platform having linearly disposed first and second chain stoppers. Each chain stopper includes a pair of pivotal doors that permit the passage of a chain in one direction while stopping the action of a chain moving in the opposite direction. The action on the pivotal doors uses gravity for vertical alignment. The pivotal doors are spaced apart the distance of a vertical chain-link in the static position and are pivotally spread apart to permit movement of the chain in one direction in the dynamic position. | 02-21-2013 |
