Claim 1
Independent Claim
120 words
Dumping mechanism for lifting and dumping a waste receptacle comprising a frame rotatably mounted on a waste collector, a cam fixedly mounted on said waste collector, an upper saddle mounted on said frame, a downwardly facing hook pivotally mounted on said frame below said saddle, means to rotate said frame to lift and tilt a waste receptacle supported thereon by engagement with said saddle, and means on the frame actuated by said cam as the frame rotates to positively pivot the hook downwardly to engage it with an abutment on said waste receptacle, said cam delaying action on the means to positively pivot the hook until after the initial rotation of the frame to lift a waste receptacle supported thereon.
Claim 2
Dependent Claim
120 words
Dumping mechanism for lifting and dumping a waste receptacle comprising a frame rotatably mounted on a waste collector, a cam fixedly mounted on said waste collector, an upper saddle mounted on said frame, a downwardly facing hook pivotally mounted on said frame below said saddle, means to rotate said frame to lift and tilt a waste receptacle supported thereon by engagement with said saddle, and means on the frame actuated by said cam as the frame rotates to positively pivot the hook downwardly to engage it with an abutment on said waste receptacle, said cam delaying action on the means to positively pivot the hook until after the initial rotation of the frame to lift a waste receptacle supported thereon.
Claim 3
Dependent Claim

Claim 4
Dependent Claim
143 words
In combination, a portable waste receptacle having an upper overhanging wall and a lower abutment on the exterior of its front wall, dumping mechanism comprising a frame rotatably mounted on a waste collector and having an upper saddle adapted to engage under said overhanging wall to support said receptacle, means to rotate said frame to lift and tilt said receptacle, said means locking the frame in loading position when said means is not operating, a cam fixedly mounted on said rotating means, a downwardly directed hook pivotally mounted on said frame, and means on the frame actuated by said cam as the frame is rotated to positively pivot said hook into engagement with said lower abutment, said cam delaying action on the means to positively pivot the hook until after the initial rotation of the frame to lift a waste receptacle supported thereon.
