Abstract
Abstract A plurality of members are arranged in side by side relation to form a plurality of horizontal rows, vertically stacked in a vertical drier. Movable means are associated with selected rows of the members and are movable to form a floor to separate one part of the drier from another part so as to maintain loads of material moving through the drier separate as the material is being dried. Means are provided to actuate the movable means in a predetermined sequence to stepwise form a floor from the top to the bottom of the drier whereby loads of material in the drier are maintained separate as they are moved through the drier.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
202 words
An arrangement for separating loads of material as the material moves through a vertical drier comprising: a. a plurality of members aligned in side by side, horizontal relation to form a plurality of horizontal longitudinally arranged rows in a vertical drier; b. movable means associated with said members to form a floor to separate one part of the drier from another part; c. means to actuate said movable means in a predetermined sequence to stepwise form a floor from the top to the bottom of the drier and thus seqentially open the floors from the top to the bottom of the drier to progressively move the material through the drier while simultaneously maintaining separate loads of material segregated as they progressively move through the drier; d. said movable means including: 1. plates pivotally secured to each side of said members; 2. spring means normally retaining said plates in retracted position to enable material to flow around the members in the drier; and 3. rotatable means connected to said plates and rotatable to move said plates into horizontal relation to engage with said next adjacent plates of said members aligned in side by side relation to thereby form a floor in the drier.
Claim 2
Dependent Claim
202 words
An arrangement for separating loads of material as the material moves through a vertical drier comprising: a. a plurality of members aligned in side by side, horizontal relation to form a plurality of horizontal longitudinally arranged rows in a vertical drier; b. movable means associated with said members to form a floor to separate one part of the drier from another part; c. means to actuate said movable means in a predetermined sequence to stepwise form a floor from the top to the bottom of the drier and thus seqentially open the floors from the top to the bottom of the drier to progressively move the material through the drier while simultaneously maintaining separate loads of material segregated as they progressively move through the drier; d. said movable means including: 1. plates pivotally secured to each side of said members; 2. spring means normally retaining said plates in retracted position to enable material to flow around the members in the drier; and 3. rotatable means connected to said plates and rotatable to move said plates into horizontal relation to engage with said next adjacent plates of said members aligned in side by side relation to thereby form a floor in the drier.
Claim 3
Dependent Claim
82 words
The invention of claim 1 wherein said movable means includes: a. plates pivotally secured to each side of said members; b. spring means normally retaining said plates in retracted position to enable material to flow around the members in the drier; and c. rotatable means connected to said plates and rotatable to move said plates into horizontal relation to engage with said next adjacent plates of said members aligned in side by side relation to thereby form a floor in the drier.
Claim 4
Dependent Claim
13 words
The invention of claim 1 wherein said rotatable means comprises a crank lever.
Claim 5
Dependent Claim
101 words
The invention of claim 3 wherein said actuating means comprises: a. an electrical circuit said circuit including: 1. motor means; 2. switch means normally open when material is thereon, and movable to closed position in the absence of material; 3. limit switch means adjacent each of said horizontal longitudinally spaced rows; and 4. manually operable switch means; b. movable means responsive upon closing said circuit when switch means (2), (3) and (4) closes to move into engagement with said rotatable means and move said plates of said members aligned in side by side relation to form a floor in the drier.
Claim 6
Dependent Claim
95 words
The invention of claim 4 wherein said switch means (2) is arranged immediately beneath each row of members aligned in side by side relation to form a floor in the drier and wherein said movable means upon contacting the next lower limit switch means adjacent a row actuates said electrical circuit to form another floor in the drier, said movable means then disengaging from the limit switch adjacent the row immediately thereby to open the circuit and disengage said movable means from said rotatable means whereupon said spring means brings said plates to retracted position.
Claim 7
Dependent Claim
35 words
The invention of claim 4 wherein said electrical circuit includes a solenoid and wherein said movable means is actuated by said solenoid to rotate said rotatable means to move said plates and form a floor.
Claim 8
Dependent Claim
57 words
The invention of claim 5 wherein each row of aligned members is provided with a movable means connected to a solenoid and wherein the solenoid remains activated to form the floor in the drier until the next lower solenoid has been actuated whereupon it engages said limit switch adjacent said row and deactivates said solenoid immediately thereabove.
Claim 9
Dependent Claim
25 words
The invention of claim 4 wherein said movable means includes paddle members to engage and rotate said crank lever of each of said rotatable means.
Claim 10
Dependent Claim
43 words
The invention of claim 8 wherein said movable means includes skid means movable simultaneously with said paddle members whereby said skid means sequentially engages said limit switch means to form a floor by said rotatable means and then open the floor immediately thereabove.
