Abstract
Abstract To facilitate the manual removal of flat articles from a conveyor two pneumatic rubber tired wheels are provided, one each side of the conveyor which are freely rotatably about parallel axes which are inclined relative to the conveyor. Flat articles travelling between the wheels are engaged thereby and tilted to lift the leading edge of the flat article from the conveyor.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
155 words
A conveyor for tiles, having a longitudinally moving conveyor belt supporting a plurality of pallets in single file with tiles resting on said pallets without any substantial overhang of the tiles from the pallets, a tile lifting mechanism comprising a pair of idler axles disposed one on each side of the conveyor, said axles each being upright and adjustably inclined in relation to the conveyor, a wheel having a resilient rim mounted for free rotation on each axle, said wheels being spaced apart to engage the edges of a tile passing therebetween so that rotation of the wheels is effected solely by frictional engagement of the rims with the moving tile to lift an individual tile above its supporting pallet, an open area downstream of said tile lifting mechanism to permit a lifted tile to be re-deposited on its pallet after passing said wheels with its rear end overhanging the downstream end of the pallet.
Claim 2
Dependent Claim
