Patent ID: 7412980

Claim:
Washing machine for glass lenses ( 11 , 11 ′) or other similar items of type including a conveyor ( 1 ) comprising a bearing surface ( 10 ) of the aforesaid glass lenses ( 11 , 11 ′) is suitable for keeping moving through a washing chamber ( 12 ) made of a sequence of washing means ( 21 ), the traction force transmitted to the aforementioned bearing surface ( 10 ) being implemented due to two chains ( 13 ) with endless links ( 14 ), located on the both sides of the aforementioned bearing surface ( 10 ), each chain ( 13 ) being joined to the longitudinal side corresponding to the aforementioned bearing surface ( 10 ) and is stretched tight between two driving gears, of parallel axis to the plane of the aforementioned bearing surface and perpendicular to the direction of the displacement of the latter, it is characteristic that, on one hand it includes two outlines ( 4 ) protecting each of two chains and that the aforementioned outlines ( 4 ) comprise a longitudinal opening ( 40 ) allowing bearing surface ( 10 ) to join to the said chains ( 13 ) located in the aforementioned outlines ( 4 ) and on the other hand, waterproofing bars joined to the bearing surface ( 10 ) to close the aforementioned longitudinal opening used in each outline ( 4 ), which pads ( 5 ) being assembled in gliding parallel to the displacement of the aforementioned bearing surface ( 10 ) due to guidance means ( 41 , 44 , 43 ).
