A sprocket wheel 7 on this shaft is connected by a chain 8 to a sprocket wheel 9 on a shaft 10 mounted in brackets 11 on part 1. Gears 12 on shaft 10 mesh with gears 13 on shafts 14 carried on standards 15 mounted on part 1. A sprocket wheel 16 is mounted on each shaft 14 and is connected by chain 17 to a sprocket wheel 18 mounted on a shaft 20, at the upper end of a bar 19, and carrying one crank 21. Each bar 19 is pivoted to the associated standard 15 and may be held in any desired position by a brace 23 secured at one end to standard 15 and at the other end to the bar 19.
