Abstract
Abstract Particle cleaning means comprising a particle receiver, a first chamber having an input opening coupled to the particle receiver, a high velocity air stream directed into the first chamber adjacent the input opening for projecting particles into the first chamber for agitated movement under the influence of the air stream, a second chamber coupled to the first chamber through an opening spaced from the input opening, a baffle between the openings to force the particles in a circuitous path through the first chamber, a first suction means coupled to the first chamber and an opposed relation to the air stream and a discharge opening in the lower end of the second chamber, and second suction means coupled to the second chamber and an opposed relation to the second opening and the discharge opening.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
248 words
A particle cleaning device comprising an enclosure having top, bottom, and side walls forming a chamber, an input opening formed in said side wall adjacent one end of said chamber for receiving the particles to be cleaned, a second opening formed in said enclosure adjacent the other end of said chamber and spaced from the input opening for discharging the particles from said chamber, said input and second opening being formed in said side walls adjacent the lower end of said enclosure, baffle means disposed between said input and second openings and extending upwardly from the bottom wall of said enclosure the upper end of said baffle means being spaced from the top wall of said enclosure, said chamber being inclined downwardly from said input opening to said second opening, said side walls diverging outwardly from their lower ends to their upper ends, high pressure fluid input means coupled to said enclosure and opening into the lower end of said chamber adjacent to said input opening and between said input opening and said baffle means for projecting said particles upwardly at high velocity into said chamber for agitated movement around said baffle means and in a circuitous path between said input and second openings for discharging from said second opening, and suction means opening into the top wall of said enclosure and in spaced relation to said high pressure input means and said input opening for removing from said chamber dust and foreign matter separated from said particles.
Claim 2
Dependent Claim
248 words
A particle cleaning device comprising an enclosure having top, bottom, and side walls forming a chamber, an input opening formed in said side wall adjacent one end of said chamber for receiving the particles to be cleaned, a second opening formed in said enclosure adjacent the other end of said chamber and spaced from the input opening for discharging the particles from said chamber, said input and second opening being formed in said side walls adjacent the lower end of said enclosure, baffle means disposed between said input and second openings and extending upwardly from the bottom wall of said enclosure the upper end of said baffle means being spaced from the top wall of said enclosure, said chamber being inclined downwardly from said input opening to said second opening, said side walls diverging outwardly from their lower ends to their upper ends, high pressure fluid input means coupled to said enclosure and opening into the lower end of said chamber adjacent to said input opening and between said input opening and said baffle means for projecting said particles upwardly at high velocity into said chamber for agitated movement around said baffle means and in a circuitous path between said input and second openings for discharging from said second opening, and suction means opening into the top wall of said enclosure and in spaced relation to said high pressure input means and said input opening for removing from said chamber dust and foreign matter separated from said particles.
Claim 3
Dependent Claim
46 words
The particle cleaning device set forth in claim 1 and including a second enclosure forming a second chamber and having an opening coupled to the discharge opening for receiving said particles and suction means coupled to said second chamber in spaced relation to said discharge opening.
Claim 4
Dependent Claim
51 words
The particle cleaning device set forth in claim 2 and including means forming a storage chamber coupled to the input opening and adapted to receive the particles to be cleaned, said storage means being elevated relative to said input opening wherein said particles will flow by gravity into said first chamber.
