Abstract

801,914. Suction devices for handling articles. VAC-U-LIFT CO. Feb. 14, 1957, No. 5068/57. Class 78 (4). The flexible annular sealing ring 19 of a suction lifting pad has a skirt whose section includes an outer straight portion 20 and an inner portion 22 meeting at a point 21 for engagement with the object 23 to be lifted; this causes the ring to sweep the surface of the object as it flexes into engagement with it. The sealing ring also has an inwardly directed lip 16 adapted to float in a groove 15 in the pad so that it makes sealing contact with the groove only after the load 23 is engaged.
