Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
166 words
A refuse packer comprising: an elongated body having a first end and a second end adapted to receive refuse therein, a refuse receiving opening on the side of said body adjacent said first end, an overhead track extending along the longitudinal axis of said elongated body, an overhead support assembly carried by said overhead track for guided movement therealong, a tilting packer blade supported from said overhead assembly arranged for reciprocal action within said body having a retracted position and a packing position, said packer blade, overhead support assembly and overhead track cooperating so that said packer blade assumes a first steep angle when in its retracted position adjacent said first end and tilts to a second steep angle which is less steeP than said first angle, when being moved in its packing position, said packing position extending from said retracted position toward said second end, and a power means for reciprocating said packer blade within said body between said retracted position and said packing position.
Claim 2
Dependent Claim
166 words
A refuse packer comprising: an elongated body having a first end and a second end adapted to receive refuse therein, a refuse receiving opening on the side of said body adjacent said first end, an overhead track extending along the longitudinal axis of said elongated body, an overhead support assembly carried by said overhead track for guided movement therealong, a tilting packer blade supported from said overhead assembly arranged for reciprocal action within said body having a retracted position and a packing position, said packer blade, overhead support assembly and overhead track cooperating so that said packer blade assumes a first steep angle when in its retracted position adjacent said first end and tilts to a second steep angle which is less steeP than said first angle, when being moved in its packing position, said packing position extending from said retracted position toward said second end, and a power means for reciprocating said packer blade within said body between said retracted position and said packing position.
Claim 3
Dependent Claim
70 words
A refuse packer as defined in claim 1 wherein said power means comprises a multistage telescoping hydraulic cylinder pivotly mounted at one end to said packer blade and pivotly mounted at the other end to a support means projecting forward from the lower said body portion of said first end of said body, said support means being adapted to fit between the driver and passenger seat of a truck chassis.
Claim 4
Dependent Claim
118 words
A refuse packer as defined in claim 1 wherein said packer blade is rigidly suspended from said overhead support assembly which assembly comprises a first roller means and a second roller means, said first and second roller means being carried by said overhead track when in the packing position, said first roller means being disposed in tandem relationship with said second roller means with said first roller means being closer to said elongated body''s first end and said second roller means being closer to said elongated body''s second end, and when said packer blade is in the retracted position said first roller means is disposed above said overhead track while said second roller means remains on said track.
Claim 5
Dependent Claim
97 words
A refuse packer as defined in claim 3 wherein said overhead track is an I-beam having two tapered flanges and a web connecting the two flanges and wherein each of said roller means comprises two tapered rollers straddling said I-beam between said flanges with the spacing between the rollers being just slightly more than the thickness of said web and the diameter of the rollers being just slightly less than the spacing between said flange but so dimensioned that upon side loading the rollers will rub on said web before they jam between the two tapered flanges.
Claim 6
Dependent Claim
59 words
A refuse packer as defined in claim 4 wherein said I-beam has a portion of its top flange removed adjacent the first end of said elongated body so as to permit said first roller means to rise up from said track and thus permit said packer blade to tilt to a more vertical angle when in the retracted position.
Claim 7
Dependent Claim
85 words
A refuse packer as defined in claim 5 wherein said power means comprises a multistage telescoping hydraulic cylinder pivotly mounted at one end to the lower half of said packer blade and pivotly mounted at its other end to a support means projecting outward from the lower portion of said first end of said body with said support means being adapted to fit between the driver and passenger seat of the cab of a truck chassis when the elongated body is mounted on said chassis.
Claim 8
Dependent Claim
38 words
A refuse packer as defined in claim 6 wherein the packer blade is at an angle of about 6* from the vertical when in a retracted position and about 15* from the vertical when in a packing position.
Claim 9
Dependent Claim
55 words
A refuse packer as defined in claim 7 wherein said elongated body has a longitudinally extending toothed member affixed on the inside at the top to prevent the packed refuse from tumbling down when the packer blade is retracted and said packer blade has a complementary slot at its top for accommodating said toothed member.
Claim 10
Dependent Claim
52 words
A refuse packer as defined in claim 8 wherein said elongated body has a longitudinally extending guide member affixed on the inside to said body for guiding said packer blade to limit said blades transverse swinging with said packer blade having a slot at its lower portion to accommodate said guide member.
Claim 11
Dependent Claim
23 words
A refuse packer as defined in claim 9 wherein the sole support for said packer blade is that provided by said roller assembly.
