Abstract

1364778 Counterbalancing WEBER-KNAPP CO 2 May 1972 [17 Nov 1971] 20430/72 Heading B8B [Also in Divisions E2 and F2] In a spring counterbalance mechanism in which a stationary member 20 is pivoted at 26 to an upwardly movable member 24, two compression springs 50, 80 act between the members; spring 50 expanding as the member 24 moves up to always counterbalance its movement and spring 80 being first compressed to act in opposition to spring 50, then being allowed to expand to help the operation of spring 50. The spring 50 acts between a mounting plate 62 fixed to member 20 and an adjusting nut 54 screwthreaded on to a bolt 52; the bolt being received in a connector 60, pivoted at 44 to the member 24. The spring 80 acts between a plate 92 fixed to member 20 and a connector 94 pivoted at 46 to member 24, and during the initial upward movement is compressed. Once pivot point 46 has moved over-centre with respect to the pivot 26, the spring 80 is free to expand. A resilient plastics brake sleeve 58 is pressed by the spring 50 into a cup shaped member 60 to frictionally engage bolt 54.
