1,022,080. Elevated single track railways. LENINGRADSKY GORNY INSTITUTE IMENI G.V. PLEKHANOVA. Dec. 19, 1963, No. 50140/63. Heading B7L. The driving wheels 1 of a locomotive or selfpropelled vehicle which grip the opposite sides of a rail or other traction element 2 are arranged on floating levers 4 pivoted at their ends to links 5, the inner ends of which are connected by yokes 6 traversing the rail 2 and to the vehicle frame through members 7. The arrangement is such that the reaction N o between the wheels 1 and rail 2 varies with the tractive effort 7. Springs 9 in the members 7 provide an initial reaction when the 'vehicle is at rest. In a first embodiment (Figs. 3 and 4) the links 5 are pivoted to adjustable blocks held in position in the floating levers 4 by bolts 30 and 32 to permit adjustment of the angle between the links 5 and rail 2 and hence the relationship between N o and T. The locomotive frame is provided with running wheels 11 and an electric motor 12 which drives the traction wheels 1 through worm gearing in casing 13, shafts 17 incorporating pairs of Hooke's joints and gearwheels 20 rigid with the wheels 1. In a second embodiment (Figs. 9, 11) a vehicle body 44 is provided with support wheels 36 and anti-sway wheels 37, respectively, engaging the top 40 and lower flanges 38 of a track 31 and is connected through members 7 with a traction mechanism with support wheels 42 on the yokes 6 and driving wheels 1 engaging the track flanges 41 and driven by motors 45.
