Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
180 words
In scrap material processing apparatus, the combination which includes: scrap material feed means bringing magnetic and nonmagnetic material into the apparatus; a first separator station including means for separating magnetic from non-magnetic material; a first receiving deck for magnetic material located adjacent said first separator station; a second receiving deck for non-magnetic material, said second deck being gravitationally spaced from said first separator station and from said first receiving deck; a second separator station including material sizing means in said first receiving deck, said sizing means comprising elongated tines having progressively increasing spaces therebetween in the direction of material flow; means gravitationally below a portion of said tines to receive material of a predetermined large size and prevent it mingling with smaller material passing gravitationally through said tines; an intermediate deck below and first deck and said tines to collect the smaller sized material, said first, second and said intermediate decks being stacked one above the other and in longitudinally off-set relation, and means operatively connected to the apparatus to vibrate said decks and cause flow of the scrap material.
Claim 2
Dependent Claim
180 words
In scrap material processing apparatus, the combination which includes: scrap material feed means bringing magnetic and nonmagnetic material into the apparatus; a first separator station including means for separating magnetic from non-magnetic material; a first receiving deck for magnetic material located adjacent said first separator station; a second receiving deck for non-magnetic material, said second deck being gravitationally spaced from said first separator station and from said first receiving deck; a second separator station including material sizing means in said first receiving deck, said sizing means comprising elongated tines having progressively increasing spaces therebetween in the direction of material flow; means gravitationally below a portion of said tines to receive material of a predetermined large size and prevent it mingling with smaller material passing gravitationally through said tines; an intermediate deck below and first deck and said tines to collect the smaller sized material, said first, second and said intermediate decks being stacked one above the other and in longitudinally off-set relation, and means operatively connected to the apparatus to vibrate said decks and cause flow of the scrap material.
Claim 3
Dependent Claim
39 words
The apparatus set forth in claim 1 wherein said second station includes means for subjecting said smaller sized material to magnetic separation; and means adjacent said second magnetic separation to direct the magnetically separated material out of the apparatus.
Claim 4
Dependent Claim
150 words
In scrap material processing apparatus, the combination which includes: a first deck extending longitudinally in the apparatus; a scrap material receiving deck above said first deck; a second deck longitudinally spaced from said receiving deck; an intermediate deck between said second deck and a portion of said first deck; means in the space between said receiving and second decks operative to separate magnetic from other materials and move the magnetic materials onto said second deck, said receiving deck having a discharge for said other materials adjacent said magnetic separator means and above said first deck; means adjacent said second deck to discriminate between acceptable and unacceptable sizes of magnetic material; a collecting deck between said discriminating means and said intermediate deck to collect the unacceptable material independently of the material collected by said intermediate deck; and means to vibrate said decks to cause the material to flow along said decks.
Claim 5
Dependent Claim
150 words
In scrap material processing apparatus, the combination which includes: a first deck extending longitudinally in the apparatus; a scrap material receiving deck above said first deck; a second deck longitudinally spaced from said receiving deck; an intermediate deck between said second deck and a portion of said first deck; means in the space between said receiving and second decks operative to separate magnetic from other materials and move the magnetic materials onto said second deck, said receiving deck having a discharge for said other materials adjacent said magnetic separator means and above said first deck; means adjacent said second deck to discriminate between acceptable and unacceptable sizes of magnetic material; a collecting deck between said discriminating means and said intermediate deck to collect the unacceptable material independently of the material collected by said intermediate deck; and means to vibrate said decks to cause the material to flow along said decks.
Claim 6
Dependent Claim
45 words
The apparatus set forth in claim 3 wherein said magnetic separating means includes a rotary drum at the space between said receiving and second decks, and each of said receiving and second decks having means adjacent said drum to vary the spacing with said drum.
Claim 7
Dependent Claim
45 words
The apparatus set forth in claim 3 wherein said receiving deck has a material discharge adjacent said magnetic separator means, and an adjustable plate is operatively mounted adjacent said discharge from said receiving deck, said plate being movable toward and away from said separator means.
Claim 8
Dependent Claim
45 words
The apparatus set forth in claim 3 wherein said second deck includes a flop gate adjacent said magnetic separator, and means resiliently supporting said gate to engage magnetic material released onto said second deck and to yield to material magnetically retained on said magnetic separator.
Claim 9
Dependent Claim
149 words
In scrap material processing apparatus, the combination which includes: a material receiving deck and a first deck spaced therefrom in substantially the same elevational plane; magnetic separator means at said space between said decks to lift magnetic material from said receiving deck and drop it on said first deck; material size discriminating means adjacent said first deck including elements arranged in spaced outwardly diverging relation to allow progressively larger magnetic scrap material to pass through with distance travelled from said first deck; a second deck gravitationally spaced from said discriminating means to catch smaller magnetic material dropping through said diverging spaces; means between said discriminating means and said second deck and located under the spaced elements to cut-off gravitational passage of predetermined larger sizes of magnetic scrap material onto said second deck, and means operatively connected to the apparatus to vibrate said decks and cause the material to flow.
Claim 10
Dependent Claim
149 words
In scrap material processing apparatus, the combination which includes: a material receiving deck and a first deck spaced therefrom in substantially the same elevational plane; magnetic separator means at said space between said decks to lift magnetic material from said receiving deck and drop it on said first deck; material size discriminating means adjacent said first deck including elements arranged in spaced outwardly diverging relation to allow progressively larger magnetic scrap material to pass through with distance travelled from said first deck; a second deck gravitationally spaced from said discriminating means to catch smaller magnetic material dropping through said diverging spaces; means between said discriminating means and said second deck and located under the spaced elements to cut-off gravitational passage of predetermined larger sizes of magnetic scrap material onto said second deck, and means operatively connected to the apparatus to vibrate said decks and cause the material to flow.
Claim 11
Dependent Claim
26 words
The apparatus of claim 7 wherein said last named means is adjustable to predetermine the size of the scrap material to be discriminated by the apparatus.
Claim 12
Dependent Claim
61 words
The apparatus of claim 7 wherein a third deck extends below said receiving deck and said second deck to receive non-magnetic material from said receiving deck, said third deck and said second deck extending into a substantially common discharge station, and means adjacent said discharge station to separate magnetic material from non-magnetic material and release the same into separate discharge paths.
