Upon movingforward, the pull of the drawbar brings the body bark into the horizontal position and locks it to the draw-bar automatically. Folding screw jacks serve to uphold either end. (To the right) One of the foldingscrew jacks with caster foot. A similar jack is sometimes used for light semi-trailers February 10, 1921 AUTOMOTIVE INDUSTRIES THE AUTOMOBILE 265. This group shines typical semi trailers in use. (Upper) The fifth-wheel connection is here automatic and I he required rocking move-ment in the relations of the trailer to the motor unit is effected by tworollers which also steer the two units into or oul of hitch, running onmils with converging guide flanges. The foldahle front support ofthe detached trailer takes the form of two substantial wheels. (Center)The use of dump bodies for semi- trailers is here exemplified. (Lower)The heavy structure, carrying the motto of the trailer industry, ispruealed with a telescoping folding jack, for supporting its front end,having a foot that rocks freely to perpi ndicular or slanting position*of the jack in connection with this phase of the subject may bebriefly mentioned separately, however. It the trailer reduces the road speed, some of its ad-vantages are lost, and it is therefore the aim to producea construction which admits of as high speed as for amotor truck alone.
