No. 961,275 of The Chisholm-Ryder Company. This harvester used a cylindrical reel having a plurality of tines spaced apart along an elongated rod, there being a plurality of such rods circumferentially spaced about the reel. The tines, as the reel rotated, were combed through the bushes so as to pull the berries therefrom and then they carried the berries upwardly until they fell therefrom into the centre of the reel. The falling berries encountered a conveyor running axially within the reel, which conveyor carried the berries laterally to another conveyor running to the rear of the harvester, from which they were deposited into a flat or other container. The Chisholm-Ryder harvester was mounted to the front of a small garden tractor and was pushed thereby through the berries.the root so that the single sheet has cooled and become rigid before coming into contact with the equipment.
The outer surfaces of the final glass sheet do not contact any part of the outside surface of the isopipe during any part of the process. Rather, these surfaces only see the ambient atmosphere. The inner surfaces of the two half sheets which form the final sheet do contact the isopipe, but those inner surfaces fuse together at the root of the isopipe and are thus buried in the body of the final sheet. In this way, the superior properties of the outer surfaces of the final sheet are achieved.
Upstream of the forming equipment is typically found a glass melting vessel, a glass fining vessel, a finer to stir chamber
