Abstract 881,938. Exercising apparatus. ARONSOHN, A. Nov. 2, 1959 [Nov. 4, 1958], No. 37110/59. Class 132(1) In an exercising appliance, a pair of cranks 5 carrying pedals 6 are mounted in front of a seat 3 and are connected by transmission means, which reverses the direction of rotation, to a second pair of cranks 21 mounted above and rotatable about an axis substantially parallel to that of cranks 5, cranks 21 being spaced from one another and having inwardly directed handles. As shown, an adjustable chair 3 is mounted on part 2 of a telescoping two part sub-frame 1, 2 whose part 1 carries an upright 4 having at its upper end a shaft carrying the cranks 5. 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. Cranks 5 and 21 can be driven by a motor connected to shaft 10 which cant also be connected by gearing 25 to a brake 24.
