Abstract

1398451 Tumbling M VAN MOPPES 4 July 1973 [28 Feb 1973] 9852/73 Heading B3D A tumbling machine for grinding or polishing semi-precious stones comprises a tumbler barrel 1 supported for rotation about its longitudinal axis and having two circular external peripheral drive surfaces 3, 5 of different diameter from each other arranged coaxially of the barrel, and drive means 6 engageable with either one of the surfaces to impart rotation to the barrel. The barrel 1 has a lid 2 and both the barrel and the lid consist of injection moulded synthetic plastics material, such as nylon, and are formed with friction rollers or gear teeth 3, 5 of different diameters. The barrel is formed with spigots 4 received in slots 9 in uprights 8 of a frame 7 which has a compartment 10 for receiving a motor unit 6 comprising the motor 12 which drives a fan 14 and a gear 15. The latter extends through an opening 9 for engaging one or other of the gears 3, 5 according to whether grinding or polishing is to be effected.
