Abstract

1379553 Mowers WOLSELEY WEBB Ltd 24 April 1972 [8 March 1971] 6289/71 Heading A1F [Also in Division F2] A belt drive disconnecting arrangement for a lawnmower comprises a pulley 12 having one flange 19 freely rotatable on a driven shaft 13 and the other flange 20 rotatably fast with the shaft 13, the flange 20 being axially movable into and out of engagement with a belt 3 to drive, and disconnect the drive from the shaft 13. The flange 20 is moved axially into engagement with the belt 3 by a manual control (not shown) which act through a Bowden cable 35, lever 31 and thrust bearing 25 on the flange 20. The flange 20 is biased away from the belt 3 by a spring 36. The shaft 13 drives a land roller 2 through gears 17, 18. The belt 3 is driven by a driving pulley 8 and drives the pulley 12 and a pulley 11 fast with a cutting cylinder 1. A manual control (not shown) acts through a Bowden cable 42 against the bias of a spring 40 to move a belt tensioning pulley 37 into engagement with the belt 3 which thus drives the pulleys 11, 12.
