HILL HOPPING A WORM DRIVE SLED (Mar, 1936)

HILL HOPPING A WORM DRIVE SLED

FROM California comes a radical innovation in motor driven vehicles, a worm drive ski-sled. Powered by a 35 horsepower engine, it negotiates the steepest, roughest inclines with ease, and on level snowfields has attained speeds of twenty and more miles per hour.
With a more powerful motor, considerably higher speeds are expected, and the initial success of the experimental model may lead
to an entirely new sport in the form of motor ski racing and jumping. In order to achieve the latter sport, it will be necessary to mount the runners on shock struts, both to protect the worm-drive blades and the rider. This would be a simple matter.
More practical vistas opened by this novel sled lie in its adaption to the needs of Arctic exploration parties in their long treks over snowbound wastes.
