Abstract
Abstract The invention is a rotary press for compacting waste paper and trash into a removable storage container. It comprises a rotating drum carrying a sliding packing blade positioned within a housing with the blade sliding in the drum as it rotates to accommodate the narrowing compaction area. A wiping blade coacts with the movement of the packing blade to sweep the compacted refuse into the storage container while the opposite end of the packing blade begins another compaction stroke.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
160 words
A two-stage rotary refuse packer, the first stage comprising: a housing including an interior chamber connected to entry and discharge pressure; a rotary drum having a diametral slot positioned in said chamber defining a compaction zone of narrowing cross-sectional area; a first blade for packing the refuse slidably positioned in said slot having a cam follower means carried on the blade; cam means in the housing for actuating the sliding movement of the first blade as the drum rotates to accommodate the narrowing compaction zone as the blade passes through the compaction stroke; the second stage including a pivotally mounted second blade in the interior chamber positioned approximate the discharge passage; and operative means connecting the second blade with the rotating drum and first blade in such a relation that the second blade actuates each time the first blade approaches the end of its compaction stroke whereby the compacted refuse is swept by the second blade into the discharge passage.
Claim 2
Dependent Claim
160 words
A two-stage rotary refuse packer, the first stage comprising: a housing including an interior chamber connected to entry and discharge pressure; a rotary drum having a diametral slot positioned in said chamber defining a compaction zone of narrowing cross-sectional area; a first blade for packing the refuse slidably positioned in said slot having a cam follower means carried on the blade; cam means in the housing for actuating the sliding movement of the first blade as the drum rotates to accommodate the narrowing compaction zone as the blade passes through the compaction stroke; the second stage including a pivotally mounted second blade in the interior chamber positioned approximate the discharge passage; and operative means connecting the second blade with the rotating drum and first blade in such a relation that the second blade actuates each time the first blade approaches the end of its compaction stroke whereby the compacted refuse is swept by the second blade into the discharge passage.
Claim 3
Dependent Claim
51 words
A rotary refuse packer as set forth in claim 1 wherein, the cam follower means comprises at least one roller mounted at each end of the blade for alternately engaging the cam means and causing the opposite end of the first blade to retract as it rotates through the compaction stroke.
Claim 4
Dependent Claim
80 words
A rotary refuse packer as set forth in claim 1 wherein, the housing includes a pair of sidewalls which define the sides of the compaction zone, the cam means comprises a recess track in one of said sidewalls and the cam follower means comprises at least one roller mounted at each end of the first blade for alternately engaging the cam means and causing the opposite end of the first blade to retract as it rotates through the compaction stroke.
Claim 5
Dependent Claim
90 words
A rotary refuse packer as set forth in claim 1 wherein, the housing includes a pair of sidewalls which define the sides of the compaction zone, the cam means comprises a recessed track with ramps at each end in at least one of said sidewalls, and cam follower means comprising at least one spring biased extending roller mounted at each end of the first blade for alternately extending into the recessed tack and causing the opposite end of the first blade to retract as it rotates through the compaction stroke.
Claim 6
Dependent Claim
62 words
A rotary refuse packer as set forth in claim 1 wherein, the second blade has a free edge which normally lies in contact with the rotating drum, and wedge means integrally mounted on the rotating drum in a position to contact the edge of the second blade and cause it to scrape any refuse away from the rotating drum and first blade.
Claim 7
Dependent Claim
52 words
A rotary refuse packer as set forth in claim 1 wherein, the second blade has a free edge normally positioned in contact with the rotating drum, and wedge means carried on the rotating drum in a position to initially actuate the second blade before said operative means further actuates the second blade.
Claim 8
Dependent Claim
124 words
A rotary refuse packer comprising: a housing having a pair of sidewalls which define an interior chamber, entry and discharge passages connected to the interior chamber; a rotary drum with a diametral slot positioned in the chamber defining a compaction zone of narrowing cross-sectional area; a packing blade carried by the drum slidably positioned within the slot for packing the refuse in the compaction zone; cam follower means attached to each end of the blade; and cam track means in the sidewalls of the housing which alternately engage the cam followers on opposite ends of the blade to retract as it rotates through the narrowing compaction zone, whereby the compacted refuse is forced through the compaction zone by opposing ends of the packing blade.
Claim 9
Dependent Claim
124 words
A rotary refuse packer comprising: a housing having a pair of sidewalls which define an interior chamber, entry and discharge passages connected to the interior chamber; a rotary drum with a diametral slot positioned in the chamber defining a compaction zone of narrowing cross-sectional area; a packing blade carried by the drum slidably positioned within the slot for packing the refuse in the compaction zone; cam follower means attached to each end of the blade; and cam track means in the sidewalls of the housing which alternately engage the cam followers on opposite ends of the blade to retract as it rotates through the narrowing compaction zone, whereby the compacted refuse is forced through the compaction zone by opposing ends of the packing blade.
Claim 10
Dependent Claim
45 words
A rotary refuse packer as set forth in claim 7 wherein, the cam track means comprises a recessed track in the sidewall of the housing, and the cam follower means includes at least one spring biased extendable roller, which normally extends into the recessed track.
Claim 11
Dependent Claim
66 words
A rotary refuse packer as set forth in claim 7 wherein, the cam track means comprises a recessed track in the sidewall of the housing with ramp means at each end of the track, and the cam follower means including at least one spring biased extendable roller which normally extends into the track and disengaging itself from the track when the roller rides up the ramp.
Claim 12
Dependent Claim
95 words
A rotary refuse packer as set forth in claim 1 wherein, the second blade normally lies in contact with the rotating drum, along the edge of the compaction zone; and the operative means comprises a mechanical linkage including an actuator arm which extends into the path of the first blade and is actuated by the first blade when the opposite end of the first blade approaches the end of its compaction stroke, whereby the second blade moves into the interior chamber forcing the compacted refuse in front of the first blade into the discharge passage.
