Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
181 words
Apparatus for compacting trash or other material comprising: a plunger having a pressure-applying compacting head; means for supporting said plunger for axial movement; means for moving said plunger axially to move said head in a compacting direction; said plunger-moving means comprising a lever extending transversely relative to the axis of siad plunger and having an opening through which said plunger extends with a plungerengaging edge; said lever being fulcrumed adjacent one end at a point spaced laterally from sais axis and having an actuating handle portion adjacent its other end and said opening being located intermediate said ends; said plunger having axially spaced shoulders which may be selectively engaged by the edge of said lever opening upon actuation of said handle portion to move said head axially in a compacting direction; biasing means cooperating with said fulcrum normally to move said edge of the lever into engagement with said plunger; said biasing means comprising a spring supporting the end of said lever by means of a hinge for swinging movement in a plane extending in the general direction of said plunger.
Claim 2
Dependent Claim
181 words
Apparatus for compacting trash or other material comprising: a plunger having a pressure-applying compacting head; means for supporting said plunger for axial movement; means for moving said plunger axially to move said head in a compacting direction; said plunger-moving means comprising a lever extending transversely relative to the axis of siad plunger and having an opening through which said plunger extends with a plungerengaging edge; said lever being fulcrumed adjacent one end at a point spaced laterally from sais axis and having an actuating handle portion adjacent its other end and said opening being located intermediate said ends; said plunger having axially spaced shoulders which may be selectively engaged by the edge of said lever opening upon actuation of said handle portion to move said head axially in a compacting direction; biasing means cooperating with said fulcrum normally to move said edge of the lever into engagement with said plunger; said biasing means comprising a spring supporting the end of said lever by means of a hinge for swinging movement in a plane extending in the general direction of said plunger.
Claim 3
Dependent Claim
28 words
Apparatus according to claim 1 in which said plunger is a rod of annular corss-section, said shoulders being provided by annular grooves formed therein at axially spaced intervals.
Claim 4
Dependent Claim
32 words
Apparatus according to claim 2 in which each of said shoulders is a flat annular shoulder at one side of the groove and at the other side of the groove is tapered.
Claim 5
Dependent Claim
45 words
Apparatus according to claim 3 in combination with the lid of a trash can or the like, said means for supporting said plunger for axial movement being carried by said lid, said lever being fulcrumed to said lid by a support fixed to said lid.
Claim 6
Dependent Claim
25 words
Apparatus according to claim 4 in which said fulcrum support comprises an upstanding spring fixed to said lid and biasing the lever toward said plunger.
Claim 7
Dependent Claim
47 words
Apparatus according to claim 5 including means for mounting the lid on a trash can, said means comprising a retaining band for engaging the can, and a hinge structure between the lid and the band for mounting the lid for swinging movement between closed and opened positions.
Claim 8
Dependent Claim
21 words
Apparatus according to claim 6 in which the hinge structure is separable to prevent removal of the lid from the band.
Claim 9
Dependent Claim
22 words
Apparatus according to claim 7 in which the band is a split clamping band, and adjustable means for connecting its ends together.
Claim 10
Dependent Claim
143 words
Apparatus for compacting trash or other material comprising: a plunger having a pressure-applying compacting head; means for supporting said plunger for axial movement; means for moving said plunger axially to move said head in a compacting direction; said plunger-moving means comprising a lever extending transversely relative to the axis of said plunger and having a plunger-engaging means; said lever being fulcrumed adjacent one end at a point spaced laterally from said axis and having an actuating handle portion adjacent its other end and said plunger-engaging means being located intermediate said ends; said plunger having axially spaced means which may be selectively engaged by tHe plunger-engaging means of said fulcrumed lever upon actuation of said handle portion to move said head axially in a compacting direction; an upstanding spring which carries a fulcrum for said lever, said spring being supported laterally of said axis.
Claim 11
Dependent Claim
