Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
163 words
A waste compacting assembly comprising an elongated hollow housing having three integral sections, the first and third sections being of constant dimension throughout their lengths, the second section tapering downwardly toward the third section so that said third section has a smaller dimension than the first section, an opening in said first section through which waste may enter, a movable compactor of cross section complimentary to said first section of the hollow housing, said compactor being slidably mounted in said first section, means in said first section to reciprocate said compactor, shearing means on said compactor and said first housing section to prevent immobilization of said compactor, the third section of said housing being adapted to have a waste receptacle mounted thereon, switch means on said housing third section interrelated with said means to reciprocate said compactor and which switch means functions to start the reciprocating movement of said compactor when the switch means is actuated by a waste receptacle being placed thereon.
Claim 2
Dependent Claim
163 words
A waste compacting assembly comprising an elongated hollow housing having three integral sections, the first and third sections being of constant dimension throughout their lengths, the second section tapering downwardly toward the third section so that said third section has a smaller dimension than the first section, an opening in said first section through which waste may enter, a movable compactor of cross section complimentary to said first section of the hollow housing, said compactor being slidably mounted in said first section, means in said first section to reciprocate said compactor, shearing means on said compactor and said first housing section to prevent immobilization of said compactor, the third section of said housing being adapted to have a waste receptacle mounted thereon, switch means on said housing third section interrelated with said means to reciprocate said compactor and which switch means functions to start the reciprocating movement of said compactor when the switch means is actuated by a waste receptacle being placed thereon.
Claim 3
Dependent Claim
19 words
The device according to claim 1, wherein said housing is cylindrical with said second section being of funnel shape.
Claim 4
Dependent Claim
26 words
the device according to claim 1, said compactor comprising a headwall, a skirt wall extending from said headwall, and a carrying means extending from said headwall.
Claim 5
Dependent Claim
27 words
The device according to claim 3, said carrying means comprising an elongated member having an internally threaded bore formed in the end thereof remote from the headwall.
Claim 6
Dependent Claim
44 words
The device according to claim 4, wherein said means to reciprocate said compactor includes a drive shaft having a threaded body portion which threadably engages the internally threaded bore formed in the carrying member for forcibly slidably moving the compactor cyclically within the housing.
