ABSTRACT:
A conveyor for providing motion of a wheeled cart, and the like, through a curve. A rigid frame supports a central fixed support and a pair of wheel guides on either side thereof. A mounting rail is slideably secured to the central support and includes a plurality of gravity dogs pivotally secured thereto. The central support, mounting rail and cart wheel guides extend through a common arc. A cylinder drive, is pivotally secured on one end to the main mount rail, and on an opposite end thereof to the frame. A control provides for alternate extension and retraction of the cylinder to provide for a back and forth ratcheting motion of the main mount rail with respect to the central support. The double pivot mounting of the drive cylinder provides for converting the linear motion thereof to the radial motion of the main mount rail relative to the central mount rail support. The gravity dogs are weighted to pivot upwards and contact the carts for moving them through the curve of the conveyor when the cylinder extends, and pivot beneath the carts when the cylinder retracts so that the dogs, after passing beneath the carts, can again push the carts upon subsequent extension of the cylinder.
