Abstract
Abstract A conveyor for elongate objects particularly glass tubes is disclosed. The conveyor is adapted to turn the tubes through 90* so that, while still travelling in the same direction they change from an orientation in line with the direction of movement to an orientation transverse the direction of movement. The conveyor includes a chain mounted on two parallel sprockets one above the other, and carrying a plurality of movable supports which are free to rotate over a limited range about a substantially vertical axis. The movable supports lift the objects in their initial orientation, rotate through 90* guided by guide members as they are lifted by the chain, and transfer the glass tubes to another conveyor, moving parallel to the production line, in their new orientation transverse the direction of movement of the conveyor.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
188 words
A conveyor device for the transfer of elongate objects, for use at the end of a continuous production line, said conveyor including a continuous elevator comprising, a chain, two substantially parallel toothed wheels carrying said chain, said toothed wheels lying one above the other and at 45* with respect to the direction of movement of said objects at the end of said production line, a plurality of movable supports for said objects, said plurality of movable supports being mounted on said chain and free to rotate relative to said chain over a limited range in substantially horizontal planes, two guides determining the angular position of said movable supports along said chain, said guides being shaped so that said movable supports are guided to be substantially parallel to said objects at a position adjacent the point where said objects leave said production line, and are rotated through 90* about a substantially vertical axis coincident with said chain as they travel up said elevator to a position where said objects are transferred, in use of said conveyor, to a horizontal transporter extending parallel to the end of said production line.
Claim 2
Dependent Claim
188 words
A conveyor device for the transfer of elongate objects, for use at the end of a continuous production line, said conveyor including a continuous elevator comprising, a chain, two substantially parallel toothed wheels carrying said chain, said toothed wheels lying one above the other and at 45* with respect to the direction of movement of said objects at the end of said production line, a plurality of movable supports for said objects, said plurality of movable supports being mounted on said chain and free to rotate relative to said chain over a limited range in substantially horizontal planes, two guides determining the angular position of said movable supports along said chain, said guides being shaped so that said movable supports are guided to be substantially parallel to said objects at a position adjacent the point where said objects leave said production line, and are rotated through 90* about a substantially vertical axis coincident with said chain as they travel up said elevator to a position where said objects are transferred, in use of said conveyor, to a horizontal transporter extending parallel to the end of said production line.
Claim 3
Dependent Claim
34 words
The conveyor device of claim 1 wherein said transfer of said objects takes place at such a height that there is sufficient space for people to pass under said transporter which carries said objects.
