## Abstract

A pressurized closure assembly is provided which has a connector assembly to allow improved application of torque in limited space conditions to rotate a head away from the hub of the closure assembly.

## Claims

### Claim 1

A pressurized closure assembly, comprising:
a hub which is connectable to a pressure vessel, said hub having a central opening;
a head which engages said hub, said head movable between an opened and a closed position;
a davit positioned adjacent said hub and extending upwardly to a position above said head for engagement with said head;
a davit post mount near an end of said davit, said davit post mount receiving a davit post and supporting said head during movement between said opened and closed positions;
said davit pivotable about a substantially vertical axis;
a connector assembly disposed on a horizontal portion of said davit spaced from said vertical axis, said connector assembly having a clamping bar and at least one plate;
said connector assembly which is connectable to said davit to apply force for rotating said davit and said head, a bar connectable to said connector assembly at a first location and extending to a second location on an opposite side of said vertical axis.

### Claim 2 (depends on 1)

The pressurized closure assembly of claim 1, said head movable upwardly and downwardly by rotation of said head.

### Claim 3 (depends on 2)

The pressurized closure assembly of claim 2, said davit post mount and said davit post being threaded.

### Claim 4 (depends on 1)

The pressurized closure assembly of claim 1, said at least one plate having one of a connection aperture or a connection protuberance.

### Claim 5 (depends on 4)

The pressurized closure assembly of claim 4, wherein said one of a connection aperture or said connection protuberance having a geometric shape.

### Claim 6 (depends on 5)

The pressurized closure assembly of claim 5, said geometric shape comprising one of square, hexagonal, or octagonal.

### Claim 7 (depends on 5)

The pressurized closure assembly of claim 5, wherein said bar has the other of a connection aperture or said protuberance of a mating shape.

### Claim 8 (depends on 1)

The pressurized closure assembly of claim 1, said connector assembly being adjustable along said davit toward or away from said vertical pivot axis.

### Claim 9 (depends on 1)

The pressurized closure assembly of claim 1 wherein said connector assembly is disposed at said davit post mount.

### Claim 10 (depends on 1)

The pressurized closure assembly of claim 1, wherein said plate has one of a connection aperture or a connection protuberance.
