Abstract
Abstract An apparatus for continuously producing blocks from scrap metal including a compression box which squeezes scrap metal loaded therein into an elongated charge and which includes a ram means for pushing this charge into an axially aligned feeding section. In the feeding section, a plate slidably mounted upon a carriage is vertically lowered behind the rear end of the charge and the charge is driven out the discharge end of the feeding section into the path of a reciprocating shearing blade by a second ram which engages the carriage. The compression box may be reloaded while the feeding and shearing operations take place whereby a continuous process is possible.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
181 words
Apparatus for continuously producing compressed blocks from scrap metal comprising a compression portion including compressing means for producing an elongated charge of compressed scrap metal and means for ejecting said charge from said compression portion, a feeding portion in communication with said compression portion for receiving the charge from said compression portion and including means for steadily feeding said charge, said feeding portion including a box-like receptacle having a bottom wall and wall means fixedly secured to opposite sides of said bottom wall defining a first open end axially aligned with, and having substantially the same size as, the open end of said compression portion whereby compressed scrap ejected from said compression portion passes into said feeding portion and said receptacle further having a second open end substantially identical in size and shape to said first open end disposed at the opposite end of said feeding portion, and a shearing portion disposed adjacent and in communication with said second opend end of said feeding portion for receiving the charge from the feeding portion and shearing same into a plurality of blocks.
Claim 2
Dependent Claim
181 words
Apparatus for continuously producing compressed blocks from scrap metal comprising a compression portion including compressing means for producing an elongated charge of compressed scrap metal and means for ejecting said charge from said compression portion, a feeding portion in communication with said compression portion for receiving the charge from said compression portion and including means for steadily feeding said charge, said feeding portion including a box-like receptacle having a bottom wall and wall means fixedly secured to opposite sides of said bottom wall defining a first open end axially aligned with, and having substantially the same size as, the open end of said compression portion whereby compressed scrap ejected from said compression portion passes into said feeding portion and said receptacle further having a second open end substantially identical in size and shape to said first open end disposed at the opposite end of said feeding portion, and a shearing portion disposed adjacent and in communication with said second opend end of said feeding portion for receiving the charge from the feeding portion and shearing same into a plurality of blocks.
Claim 3
Dependent Claim
152 words
Apparatus as recited in claim 1 wherein said means for steadily feeding said charge comprises a rigid plate member which is mounted in a plate mounting member which includes lift means for producing vertical movement of said plate member in a plane perpendicular to said wall means of said feeding portion from a lowered position which completely closes the opening defined by said wall means and bottom wall to a raised position disposed above said wall means, said apparatus further including a drive means for sliding said plate mounting member along said receptacle from a first position adjacent said compression portion to a second position adjacent said shearing portion whereby said plate member may be disposed in said raised position to receive said charge from said compression portion and in said lowered position for steadily feeding said charge when said drive means causes said plate mounting member to slide along said receptacle.
Claim 4
Dependent Claim
35 words
Apparatus as recited in claim 2 wherein said plate mounting member further comprises a carriage mounted for movement adjacent and parallel to the longitudinal axis of said feeding portion, and means for moving said carriage.
Claim 5
Dependent Claim
43 words
Apparatus as recited in claim 3 wherein the portions of said wall means of said feeding portion opposite said bottom wall each include an axially aligned slot and said carriage includes lugs which engage said slots whereby said carriage is mounted for movement.
Claim 6
Dependent Claim
18 words
Apparatus as recited in claim 3 wherein said means for moving said carriage comprises a reciprocating fluid motor.
Claim 7
Dependent Claim
71 words
Apparatus as recited in claim 2 wherein said lift means comprises at least one cylinder mounted to said carriage and including a piston fixedly attached to said plate member, a hydraulic lift system, an electrical motor and pump driven by said electrical motor both being mounted upon said pump for generating flow through said hydraulic lift system to extend said piston from said cylinder and electrical operators for controlling said motor.
Claim 8
Dependent Claim
68 words
Apparatus as recited in claim 1 further including a lid means pivotally mounted adjacent said feeding portion for movement from an open position to a closed position in which said open top of said feeding portion is at least substantially closed in the area adjacent said shearinG portion and means for moving said lid means from said open to said closed and said closed to said open position.
Claim 9
Dependent Claim
37 words
Apparatus as recited in claim 7 wherein said moving means comprises a hydraulic cylinder securely fixed adjacent said feeding portion and a piston movably disposed within said cylinder and fixed at one end to said lid means.
Claim 10
Dependent Claim
34 words
Apparatus as recited in claim 1 wherein said shearing portion comprises a shear blade mounted for vertical movement across said second open end of said feeding portion to shear said compressed change into blocks.
Claim 11
Dependent Claim
152 words
Apparatus for continuously producing compressed blocks from scrap metal comprising: a horizontally elongated compression box for compressing a charge of scrap metal into an elongated compacted mass; a horizontally elongated open-ended shear feed box disposed adjacent one end of said compression box on the longitudinal axis of said compression box for receiving a compacted mass of scrap metal from said compression box; an ejection ram for engaging the end of a compacted mass of scrap metal in said compression box and for ejecting the mass from said compression box into said feed box; shearing means disposed adjacent the end of said feed box remote from said compression box for shearing a compacted mass of scrap metal into a plurality of blocks; and means for engaging the end of the compacted mass of scrap metal remote from said shearing means and for moving the mass through said feed box toward said shearing means.
Claim 12
Dependent Claim
152 words
Apparatus for continuously producing compressed blocks from scrap metal comprising: a horizontally elongated compression box for compressing a charge of scrap metal into an elongated compacted mass; a horizontally elongated open-ended shear feed box disposed adjacent one end of said compression box on the longitudinal axis of said compression box for receiving a compacted mass of scrap metal from said compression box; an ejection ram for engaging the end of a compacted mass of scrap metal in said compression box and for ejecting the mass from said compression box into said feed box; shearing means disposed adjacent the end of said feed box remote from said compression box for shearing a compacted mass of scrap metal into a plurality of blocks; and means for engaging the end of the compacted mass of scrap metal remote from said shearing means and for moving the mass through said feed box toward said shearing means.
Claim 13
Dependent Claim
81 words
Apparatus as in claim 10 wherein said means for engaging the end of a compacted mass of scrap metal and moving the mass toward said shearing means includes a vertically disposed door which is slidable between positions in which it opens and closes the end of said feed box adjacent said compression box, and wherein said ejection ram has a stroke sufficient to push a compacted mass of scrap metal past said door when the latter is in its open position.
Claim 14
Dependent Claim
26 words
Apparatus as in claim 10 wherein said door is supported on a carriage which is mounted for reciprocating movement along the length of said feed box.
