## Abstract

An ice bagger is provided. The ice bagger includes an ice hopper into which ice is disposed from an ice manufacturer. The ice hopper further includes an ice agitator. The ice hopper defines an ice trough positioned beneath the ice hopper. An ice auger is housed inside the ice trough. The ice auger transports ice to an ice delivery chute. A hatch is positioned beneath the ice delivery chute, upon which the bag rests while filling. The ice delivery chute and the hatch define a bag filling area such that, when bags are present in the bag filling area, the bags are positioned to be filled. A scale is positioned on the hatch. The scale weighs the ice being deposited into the bag. When the bag is full, the bag is sealed by a sealer. When the bag is sealed, the hatch opens and the bag of ice is deposited in an bag depository. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

## Claims

### Claim 1

An ice bagger comprising:
a funnel-shaped ice hopper adapted to receive ice from an ice manufacturer, the ice hopper defining an aperture thereunder;
an ice agitator disposed in the ice hopper, the ice agitator including a bar having a plurality of fingers adapted to stir and churn ice in the ice hopper;
an ice trough operably positioned beneath the ice hopper aperture and being adapted to receive ice from the ice hopper, the ice trough defining an aperture thereunder at one end of the ice trough;
a channel extending from an end of the ice trough opposite the trough aperture to an outside surface of the ice bagger, the channel configured to channel accumulated water away from the ice trough;
an ice auger housed inside the ice trough, the ice auger adapted to transport ice in a substantially horizontal direction from beneath the ice hopper towards the ice trough aperture;
an ice delivery chute positioned beneath the ice trough aperture;
a hatch positioned beneath the ice delivery chute, the hatch adapted to release a filled bag for storage, the ice delivery chute and the hatch defining a bag filling area such that, when bags are present in the bag filling area, the bags are positioned to be filled;
at least one sensor that detects the level of ice in the ice hopper; and
a bag deliverer adapted to deliver bags from a supply of bags to the bag filling area, the bag deliverer comprising a bag tension bar adapted to provide tension to the supply of bags to help prevent the stream of bags from displacing off the bag track,
wherein the bag deliverer further comprises a bag holder, and the bag holder is mounted on two rails to allow the bag holder to slide out of the ice bagger for easy replacement of a roll of bags.

### Claim 2 (depends on 1)

The ice bagger of claim 1, wherein the plurality of fingers on the ice agitator are positioned generally perpendicular to the longitudinal axis of the bar.

### Claim 3 (depends on 1)

The ice bagger of claim 1, wherein the bag holder is adapted to receive and store the supply of bags, wherein the supply of bags comprises a roll of a plurality of preformed connected bags;
wherein the bag deliverer further comprises a plurality of bag rollers adapted to transport the then connected bags from the roll of bags in the bag filling area; and
sensors and guides adapted to position the bags for filling.

### Claim 4 (depends on 1)

The ice bagger of claim 1, further comprising a blower positioned with respect to the bag filling area and being adapted to open the mouth of a bag prior to ice being deposited in the bag.

### Claim 5 (depends on 1)

The ice bagger of claim 1, further comprising a sealer adapted to seal the bag when the bag is full.

### Claim 6 (depends on 5)

The ice bagger of claim 5, wherein the sealer comprises a heat seal bar and a heat seal element.

### Claim 7 (depends on 1)

The ice bagger of claim 1, further comprising a microprocessor adapted to control at least one component of the ice bagger.

### Claim 8 (depends on 1)

The ice bagger of claim 1, wherein the bar extends horizontally along the length of the hopper, the bar adapted to rotate around a horizontal axis along the length of the hopper.

### Claim 9

An ice bagger comprising:
a generally funnel-shaped ice hopper adapted to receive ice from an ice manufacturer, the ice hopper defining an ice hopper aperture thereunder;
an ice trough operably positioned beneath the ice hopper aperture and being adapted to receive ice from the ice hopper, the ice hopper aperture and the ice trough being substantially co-extensive, the ice trough defining a bottom surface that is inclined towards a trough aperture such that water that has accumulated in the ice trough drains away from the trough aperture;
a channel extending from an end of the ice trough opposite the trough aperture to an outside surface of the ice bagger, the channel configured to channel accumulated water away from the ice trough;
an ice auger housed inside the ice trough, the ice hopper aperture, the ice trough, and the ice auger being substantially co-extensive, the ice auger in driving connection with a motor, the ice auger adapted to transport ice along the ice trough towards the trough aperture at an incline sufficient to cause water resulting from melted ice to drain away from the trough aperture;
an ice agitator comprising a bar extending along the length of the hopper, the bar adapted to rotate around an axis along the length of the hopper, the bar having a plurality of fingers positioned perpendicular to a longitudinal axis of the bar to provide horizontal agitation to stir and churn ice in the ice hopper to prevent ice from bridging;
an ice delivery chute positioned beneath the trough aperture;
a hatch positioned beneath the ice delivery chute, the hatch adapted to release a filled bag for storage, the ice delivery chute and the hatch defining a bag filling area such that, when bags are present in the bag filling area, the bags are positioned to be filled;
a scale positioned on the hatch, the scale positioned to weigh the ice being deposited in the bag to determine when a designated amount of ice has been deposited into the bag;
at least one sensor that detects the level of ice in the ice hopper;
a bag deliverer to deliver bags to the bag filling area, the bag deliverer comprising a bag tension bar adapted to provide tension to the supply of bags to help prevent the stream of bags from displacing off the bag track; and
a microprocessor adapted to control at least one component of the ice bagger,
wherein the bag deliverer further comprises a bag holder, and the bag holder is mounted on two rails to allow the bag holder to slide out of the ice bagger for easy replacement of a roll of bags.
