Abstract
Abstract A device for aiding in separating a comingled mass of containers being transported on a pair of conveyor belts. The device includes a cam means which is reciprocally moved up and down for raising and lowering the inner edge of the conveyor belts from a horizontal to a tilted position. This vibrates the containers preventing them from becoming wedged against vertical divider plates which are used for separating the containers into rows.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
172 words
A device for aiding in separating a comingled mass of containers being moved on at least a pair of driven conveyor belts into rows, said conveyor belts being positioned adjacent each other with the inner edges thereof running parallel to each other, vertically extending divider plates are carried above the conveyor belts for separating and maintaining the containers in rows as they are moved on the conveyor belts, said device comprising: a. an eccentrically mounted cam carried below said conveyor belts in engagement with the inner edges of said belts directly ahead of said divider plates, and b. means for alternately raising and lowering said cam means causing said inner edges of said conveyor belts directly ahead of said divider plates to be reciprocally raised and lowered, said containers being moved on said belts being raised and lowered with said belts, whereby the movement of said containers caused by being raised and lowered prevents said containers from becoming jammed against the ends of said divider plates as they are separated into rows.
Claim 2
Independent Claim
172 words
A device for aiding in separating a comingled mass of containers being moved on at least a pair of driven conveyor belts into rows, said conveyor belts being positioned adjacent each other with the inner edges thereof running parallel to each other, vertically extending divider plates are carried above the conveyor belts for separating and maintaining the containers in rows as they are moved on the conveyor belts, said device comprising: a. an eccentrically mounted cam carried below said conveyor belts in engagement with the inner edges of said belts directly ahead of said divider plates, and b. means for alternately raising and lowering said cam means causing said inner edges of said conveyor belts directly ahead of said divider plates to be reciprocally raised and lowered, said containers being moved on said belts being raised and lowered with said belts, whereby the movement of said containers caused by being raised and lowered prevents said containers from becoming jammed against the ends of said divider plates as they are separated into rows.
Claim 3
Dependent Claim
68 words
The device as set forth in claim 1 further comprising: a. an elongated member positioned between said cam and the bottom side of said conveyor belts; b. means for pivotally supporting one end of said elongated member so that as said cam is rotated, the other end of said elongated member is alternately raised and lowered for alternately raising and lowering said inner edges of said conveyor belts.
Claim 4
Independent Claim
150 words
A device for aiding in separating a comingled mass of containers being moved on a pair of driven conveyor belts into rows, said conveyor belts being positioned adjacent each other with the inner edges thereof running parallel to each other, said device comprising: a. cam means carried below said conveyor belts in engagement with the inner edges of said belts; b. means for alternately raising and lowering said cam means causing said inner edges of said conveyor belts to be alternately shifted between a horizontal position and a position wherein said conveyors slope downwardly from their inner edges towards said outer edges; and c. vertically extending divider plates carried above said conveyors after said cam means for separating said containers into rows; whereby the raising and lowering of said conveyor belts prevents said containers from becoming jammed against the ends of said divider plates as they are separated into rows.
Claim 5
Independent Claim
150 words
A device for aiding in separating a comingled mass of containers being moved on a pair of driven conveyor belts into rows, said conveyor belts being positioned adjacent each other with the inner edges thereof running parallel to each other, said device comprising: a. cam means carried below said conveyor belts in engagement with the inner edges of said belts; b. means for alternately raising and lowering said cam means causing said inner edges of said conveyor belts to be alternately shifted between a horizontal position and a position wherein said conveyors slope downwardly from their inner edges towards said outer edges; and c. vertically extending divider plates carried above said conveyors after said cam means for separating said containers into rows; whereby the raising and lowering of said conveyor belts prevents said containers from becoming jammed against the ends of said divider plates as they are separated into rows.
