Abstract
Abstract Apparatus for making small lumps from scrap materials, such as motor vehicles, used cars and the like, comprising means for compressing the scrap materials into a compact columnar block, and cutting means including at least two spaced and juxtaposed lower shearing dies, and at least one upper shearing die adapted to be reciprocable into the space between said lower shearing dies, whereby it is possible to form small lumps of high compactness from scrap materials, such as used cars.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
150 words
An apparatus for forming small lumps from scrap materials, such as motor vehicles and the like, comprising means for compressing scrap materials into a compact columnar block, said compressing means being substantiallY oblong and having an open inlet top and an outlet end, means for cutting the block into small lumps, said cutting means being substantially vertically disposed at said outlet end of the compressing means, at least two spaced and juxtaposed lower dies and at least one upper die for shearing the block, said upper die being reciprocable into the space between said lower dies, at least two reciprocable presser blocks disposed on both sides of said upper die and adapted to hold the block in cooperation with said lower dies during the shearing operation, and elastic supports for said presser blocks from said upper die so as to elastically hold the block in cooperation with said lower dies.
Claim 2
Independent Claim
150 words
An apparatus for forming small lumps from scrap materials, such as motor vehicles and the like, comprising means for compressing scrap materials into a compact columnar block, said compressing means being substantiallY oblong and having an open inlet top and an outlet end, means for cutting the block into small lumps, said cutting means being substantially vertically disposed at said outlet end of the compressing means, at least two spaced and juxtaposed lower dies and at least one upper die for shearing the block, said upper die being reciprocable into the space between said lower dies, at least two reciprocable presser blocks disposed on both sides of said upper die and adapted to hold the block in cooperation with said lower dies during the shearing operation, and elastic supports for said presser blocks from said upper die so as to elastically hold the block in cooperation with said lower dies.
Claim 3
Independent Claim
128 words
An apparatus for forming small lumps from scrap materials, such as motor vehicles and the like, comprising means for compressing scrap materials into a compact columnar block, said compressing means being substantially oblong and having an open inlet top and an outlet end, means for cutting the block into small lumps, said cutting means being substantially vertically disposed at said outlet end of the compressing means, at least two spaced and juxtaposed lower dies and at least one upper die for shearing the block, said upper die being reciprocable into the space between said lower dies, and a pusher block for pushing out the lumps received in the space between said lower dies, said pusher block having a top bevelled surface and being slidably arranged in said space.
Claim 4
Independent Claim
128 words
An apparatus for forming small lumps from scrap materials, such as motor vehicles and the like, comprising means for compressing scrap materials into a compact columnar block, said compressing means being substantially oblong and having an open inlet top and an outlet end, means for cutting the block into small lumps, said cutting means being substantially vertically disposed at said outlet end of the compressing means, at least two spaced and juxtaposed lower dies and at least one upper die for shearing the block, said upper die being reciprocable into the space between said lower dies, and a pusher block for pushing out the lumps received in the space between said lower dies, said pusher block having a top bevelled surface and being slidably arranged in said space.
Claim 5
Independent Claim
214 words
An apparatus for forming small lumps from scrap materials, such as motor vehicles and the like, comprising means for compressing scrap materials into a compact columnar block, said compressing means being substantially oblong and having an open inlet top and an outlet end, means for cutting the block into small lumps, said cutting means being substantially vertically disposed at said outlet end of the compressing means, at least two spaced and juxtaposed lower dies and at least one upper die for shearing the block, said upper die being reciprocable into the space between said lower dies, wherein said compressing means includes at least one compression box and at least one force plate reciprocable in said box for compressing the scrap materials into the block, and wherein said compression box is provided with a delivery port at said outlet end, open to said cutting means, a push plate arranged reciprocably on the side of said compression box opposite to said delivery port, and slidable door means between said delivery port and said push plate, said door means acting in its closed condition as a crushing wall for the scrap materials, said plate being adapted to push the block into said cutting means through said delivery port when said door means is in its open condition.
Claim 6
Independent Claim
214 words
An apparatus for forming small lumps from scrap materials, such as motor vehicles and the like, comprising means for compressing scrap materials into a compact columnar block, said compressing means being substantially oblong and having an open inlet top and an outlet end, means for cutting the block into small lumps, said cutting means being substantially vertically disposed at said outlet end of the compressing means, at least two spaced and juxtaposed lower dies and at least one upper die for shearing the block, said upper die being reciprocable into the space between said lower dies, wherein said compressing means includes at least one compression box and at least one force plate reciprocable in said box for compressing the scrap materials into the block, and wherein said compression box is provided with a delivery port at said outlet end, open to said cutting means, a push plate arranged reciprocably on the side of said compression box opposite to said delivery port, and slidable door means between said delivery port and said push plate, said door means acting in its closed condition as a crushing wall for the scrap materials, said plate being adapted to push the block into said cutting means through said delivery port when said door means is in its open condition.
Claim 7
Dependent Claim
84 words
The apparatus as defined in claim 3, wherein said compression box includes a primary box and a secondary box disposed in rectilinearly aligned relationship with said primary box, said door means being disposed between said boxes, and wherein said force plate includes a primary force plate reciprocable in said primary box for compressing the scrap materials in a first direction and a secondary force plate reciprocable in said secondary box for compressing the same in a second direction substantially perpendicular to the first direction.
Claim 8
Dependent Claim
114 words
The apparatus as defined in claim 4, wherein said primary box is provided with a delivery port open to said secondary box and a push plate arranged reciprocably on the side of said primary compression box opposite to said delivery port, said secondary box being also provided with a delivery port open to said cutting means and disposed on the side of said secondary compression box opposite to said first-named delivery port of the primary box, and said push plate is adapted to push out the block from said primary compression box through its delivery port into said secondary compression box and further through said delivery port of the latter into said cutting means.
