Abstract
Abstract An apparatus for transferring a plurality of individual units from a conveyor having one velocity in a given direction and changing the velocity of the units to a second value in the same direction. The units are engaged individually by elements of a second conveyor having a velocity component in the given direction the same as that of the units at the time of engagement of the elements with the units.

Claim 1
Independent Claim
263 words
A conveyor system for changing substantially the velocity of continuously traveling units without substantial shifting of the arrangement of the units from a given disposition relative to each other, comprising, in combination, a first conveyor having a surface for supporting and continuously advancing a plurality of units along a first path at a predetermined linear velocity with the units thereon disposed in predetermined positions relative to each other, and a second conveyor for receiving said units from said first conveyor and for advancing said units upwardly along a second path at a linear velocity substantially different from the linear velocity imparted to the units by said first conveyor, said second conveyor having a plurality of upwardly moving carrier unit-supporting surfaces each adapted to receive one of said units, said first and second conveyors being disposed relative to each other with said second path intersecting said first path at an angle such that the component of the linear velocity of each of said unit-supporting surfaces of said carriers in the direction of movement of the unit-supporting surface of said first conveyor at the intersection of said paths is equal to the linear velocity of the unit-supporting surface of said first conveyor at said intersection so that the only significant additional force imparted to the unit is in the direction substantially normal to the unit receiving surface of said conveyors, and the arrangement of the units relative to one another will not be effected, said conveyors being adapted to effect a transfer of units between said first and second conveyors at said point of intersection.
