Abstract
Abstract Double leg suspended poultry dropped from a moving conveyor and guided into bags by a nozzle assembly that effects limited expansion of each bag in advance of entry of each bird into the bag. A ram packs each bird fully into the bag after partial entry resulting in tight fit packaging upon withdrawal of the ram and nozzle assembly from the bag as it is detached and dropped onto a receiving surface.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
85 words
In combination with a moving conveyor from which a single irregular-shaped, compressible object is dropped at a packaging station for guided gravitational descent along an entry passage extending into a single inflated bag made of stretchable material, movable nozzle means projected into the bag in response to release of the object from the conveyor for establishing said entry passage into the bag, and ram means engageable with the object only following partial entry thereof through said entry passage for packing the object into the bag.
Claim 2
Dependent Claim
85 words
In combination with a moving conveyor from which a single irregular-shaped, compressible object is dropped at a packaging station for guided gravitational descent along an entry passage extending into a single inflated bag made of stretchable material, movable nozzle means projected into the bag in response to release of the object from the conveyor for establishing said entry passage into the bag, and ram means engageable with the object only following partial entry thereof through said entry passage for packing the object into the bag.
Claim 3
Dependent Claim
42 words
The combination of claim 1 including blower means for inflation of the bag prior to drop of the object at the packaging station and means for interrupting said inflation of the bag by the blower means during establishment of said entry passage.
Claim 4
Dependent Claim
53 words
The combination of claim 1 including means for expanding the nozzle means during projection thereof into the bag to cause dimensional enlargement of the bag, and actuating means for effecting advancement of the nozzle means and the ram means in sequence followed by simultaneous retraction of the nozzle means and the ram means.
Claim 5
Dependent Claim
18 words
The combination of claim 1 wherein said object is a bird suspended by both legs from the conveyor.
Claim 6
Dependent Claim
55 words
The combination of claim 1 wherein said nozzle means includes a pair of confronting guide members engageable with the object during entry thereof into the bag, and linkage means connected to the guide members for positioning thereof to dimensionally vary said entry passage and compress the object laterally during said partial entry into the bag.
Claim 7
Dependent Claim
32 words
The combination of claim 5 including actuator means connected to the linkage means for displacing said guide members laterally while projecting the guide members into the bag in advance of the object.
Claim 8
Dependent Claim
96 words
In combination with a moving conveyor from which an irregular-shaped compressible object is dropped at a packaging station for guided descent into a flexible container having an opened end portion, nozzle means engageable with the object for lateral compaction thereof during said descent into the container, actuator means connected to the nozzle means for projection thereof into said opened end portion of the container in advance of the object and ram means engageable with the object only following partial entry thereof into the container for displacing the object through the nozzle means fully into the container.
Claim 9
Dependent Claim
96 words
In combination with a moving conveyor from which an irregular-shaped compressible object is dropped at a packaging station for guided descent into a flexible container having an opened end portion, nozzle means engageable with the object for lateral compaction thereof during said descent into the container, actuator means connected to the nozzle means for projection thereof into said opened end portion of the container in advance of the object and ram means engageable with the object only following partial entry thereof into the container for displacing the object through the nozzle means fully into the container.
Claim 10
Dependent Claim
23 words
The combination of claim 7 including means for clamping the bag to the nozzle means during entry of the object into the bag.
