Abstract

878,714. Load handling apparatus. AMALGAMATED DENTAL CO. Ltd. June 16, 1959 [June 16, 1958], No. 19193/58. Class 78 (3). A body support 13, such as a dental seat or operating table, is moved relative to a base 1 by a pair of lazy tong linkages 6 connected at 5 to the movable cylinder 4 of a jack which is extended by applying compressed air above the surface of liquid which is contained in the base, and is communicated to cylinder 4 by a conduit 15 and a pneumatically operated shuttle valve 16. Rollers 8 are guided in slots 9 in the base and support, and a link 14 is provided to prevent the support moving laterally.
