Abstract
Abstract A top-loading trash compactor primarily for institutional use and comprising a counter top height cabinet with two cubicles with trash containers therein, the cabinet top panel having two trash loading hatchways therein, one for each cubicle. The cabinet top panel is spaced above the containers to provide a ram shuttle way below the panel top and above the containers. A single ram is mounted in the shuttle way for shuttle movement from one cubicle to the other. When the ram is in one cubicle, it is utilized to compact trash previously loaded into the container in that cubicle. This exposes the other container to receive trash loaded thereinto through its open hatchway. The ram carries a hatch cover or shield to close the hatchway above the cubicle in which the ram is working and opens the hatchway above the other cubicle.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
190 words
A top loading trash compactor comprising a low profile cabinet having two cubicles for trash containers therein, a cabinet top with two trash loading hatchways therein, one for each cubicle, said top being spaced above the containers to provide a ram shuttle way below the top and above the containers, a single ram, means mounting said ram in said shuttle way for shuttling movement from one cubicle to the other whereby when the ram is in one cubicle it is clear of the other cubicle to permit loading of trash into said other cubicle through its said hatchway, said ram having a ram platen and means for extending the ram platen deep into a trash container for compaction of trash therein and retracting said ram platen above the level of the container top and into said shuttle way for clearance of said containers during shuttling movement of said ram, and hatch cover means to close the hatchway above one cubicle in which the ram is working and open the hatchway above the other cubicle and permit trash loading into said other cubicle concurrently with ram operation in the one cubicle.
Claim 2
Dependent Claim

The compactor of claim 1 in which said hatch cover means comprises a shield over said ram and movable therewith.
Claim 4
Dependent Claim
47 words
The compactor of claim 2 in combination with power means to move the ram along said shuttle way, and control means for said power means responsive to engagement of said hatch cover panel with an obstruction to disengage said power means in the event of such engagement.
Claim 5
Dependent Claim
48 words
The compactor of claim 3 in which said control means comprises a switch, a switch actuator on the shield and a yieldable mounting for the shield whereby such engagement will cause the shield to yield and engage the switch actuator with the switch and disengage the power means.
Claim 6
Dependent Claim
27 words
The compactor of claim 4 in which the yieldable mounting comprises a slide mount for the shield and spring means centering said shield on said slide mount.
Claim 7
Dependent Claim
21 words
The compactor of claim 1 in which the means for extending and retracting the ram platen comprises a lazy tong assembly.
Claim 8
Dependent Claim
78 words
The compactor of claim 1 in which the means for extending and retracting the ram platen comprises paired laterally spaced lazy tongs, corresponding ends thereof being connected by cross yokes, drive nuts pivotally mounted in said yokes and a drive screw engaged in said nuts, the pivotal mounting of the nuts in the yokes relieving stresses which would otherwise be exerted between the nuts and drive screw in the event of uneven loading on said paired lazy tongs.
Claim 9
Dependent Claim
79 words
The compactor of claim 1 in which the means mounting the ram comprises a bridge with a ram motor mounted near one end thereof, said cabinet having a motor way aligned with the motor and within which the motor travels as the ram shuttles from one end of the cabinet to the other, and a flexible shield mounted on the bridge and movable therewith to partition the shuttle way from the motor way in all positions of the bridge.
Claim 10
Dependent Claim
37 words
The compactor of claim 8 in which the bridge extends across both the shuttle way and the motor way, said cabinet having tracks extending longitudinally of the cabinet and said bridge having carriages movable along said tracks.
Claim 11
Dependent Claim
19 words
The compactor of claim 9 in which the bridge has elongated stabilizer arms on which said carriages are mounted.
Claim 12
Dependent Claim
58 words
The compactor of claim 1 in which the bottom of the cabinet is provided with dollies for the containers, each said dolly having a platform directly supporting its container, a floor contacting wheel at the front edge of the dolly, tracks along the cabinet bottom and slides complementary to said tracks along the sides of the dolly platform.
