## Abstract

A method and system using a single pass sequencer having a transport system for transporting the mail pieces to a transport system having a moveable carriage system and a stationary carriage system with a plurality of holders slidable between the moveable carriage system and the stationary carriage system. The plurality of holders hold a mail piece of the mail pieces received from the transport system. The mail pieces are sequenced as they are transported or moved from the stationary carriage to the moveable carriage.

## Claims

### Claim 1

A method of sorting objects, comprising the steps of:
inducting objects into separate holders on a first carriage;
transporting the separate holders from the first carriage to a second carriage, in substantially a same order;
instructing the separate holders to move from the second carriage to a corresponding positions of a plurality of assigned positions on the first carriage, incrementally and in sequence, based on sorting criteria read from the objects; and
unloading the sequenced objects from each of the separate holders on the first carriage.

### Claim 2 (depends on 1)

The method of claim 1, further comprising incrementally moving the first carriage to align each of the separate holders with an empty location on the second carriage prior to the transporting step.

### Claim 3 (depends on 2)

The method of claim 2, wherein:
the sorting criteria includes codes assigned to the separate holders and the plurality of assigned positions on the first carriage based on information associated with the objects, and
the separate holders are moved in a sequential order from the second carriage to the first carriage based on an alignment of the codes and a final sort order.

### Claim 4 (depends on 1)

The method of claim 1, wherein the objects are mail pieces.

### Claim 5 (depends on 1)

The method of claim 1, further comprising placing a packager or packagers at a predetermined position with respect to the first carriage such that the objects are unloaded from each of the separate holders of the first carriage in the sequential order into the packager.

### Claim 6 (depends on 1)

The method of claim 1, wherein the first carriage is a moveable carriage and the second carriage is a stationary carriage.

### Claim 7 (depends on 1)

The method of claim 1, further comprising:
incrementing the first carriage prior to transporting the separate holders onto the second carriage; and
maintaining the second carriage in a stationary position during the transporting and the move steps.

### Claim 8

A method of sequencing objects, comprising:
placing non-sequenced mail pieces in separate holders extending from a moveable carriage;
incrementally moving the moveable carriage and aligning each separate holder filled with one of the non-sequenced mail pieces with a next empty position on a stationary carriage;
moving the separate holders from the moveable carriage to each of the next empty position on the stationary carriage;
assigning codes to the mail pieces and positions on the moveable carriage based on final destination sequence;
moving each of the separate holders from the stationary carriage to the moveable carriage, in a delivery order sequence, based on the assigned codes; and
unloading the mail pieces from the holders on the moveable carriage at a predetermined location in the sequence.

### Claim 9 (depends on 8)

The method of claim 8, wherein the separate holders are sequenced as they are moved onto the moveable carriage.

### Claim 10 (depends on 8)

The method of claim 8, further comprising placing one or more packagers at a predetermined position with respect to the moveable carriage such that the sequenced mail pieces are unloaded from each of the separate holders in the delivery order sequence into the one or more packagers or containers.

### Claim 11 (depends on 8)

The method of claim 8, wherein the separate holders are moved from the moveable carriage to each of the next empty position on the stationary carriage in a same order as originally on the moveable carriage.

### Claim 12 (depends on 8)

The method of claim 8, further comprising the step of instructing each of the separate holders to release the sequenced mail pieces during the unloading step.

### Claim 13 (depends on 8)

The method claim 8, further comprising the steps of:
unloading the mail pieces from the holders on the moveable carriage at a predetermined location into a container or packager in the delivery order sequence;
determining whether the container or packager is full; and
if so, then incrementing the container or packager and inserting a new container or packager at the predetermined location.

### Claim 14

A method comprising:
feeding non-sequenced objects to separate holders extending from a carriage movable in at least one direction;
assigning codes to positions on the moveable carriage based upon information on the non-sequenced objects; and
transporting the non-sequenced objects in the separate holders back and forth between the moveable carriage and a stationary carriage to sort the non-sequenced objects stored in the separate holders into a sequence.

### Claim 15 (depends on 14)

The method of claim 14, further comprising disconnecting a releasable latch mechanism of the separate holders at a predetermined time or location to discharge the objects therefrom.

### Claim 16 (depends on 14)

The method of claim 14, further comprising releasing a bottom of the separate holders to discharge the object therefrom.

### Claim 17 (depends on 14)

The method of claim 14, further comprising:
transporting each of the separate holders between the moveable carriage and the stationary carriage via sliding or rolling.

### Claim 18 (depends on 14)

The method of claim 14, further comprising reading the information on the objects and delivering the information to a sort computer to assign sort codes to the separate holders, instructing movement of the moveable carriage, incrementally, and transporting the separate holders to the stationary carriage in the delivery sequence based on the sort codes.

### Claim 19 (depends on 14)

The method of claim 14, wherein the moveable carriage is movable in two directions for loading of the non-sequenced objects and unloading of the objects, in a sequence.

### Claim 20 (depends on 14)

The method of claim 14, wherein the objects are mail pieces.
