Abstract: To obtain unequal angles of turn for two-steerable wheels of a vehicle inexpensively, each wheel is turned through a gear. The two gears have a center to center distance corresponding to the track of the steerable wheels and are dimensioned to accommodate therebetween a meshing pinion mounted eccentrically on a swing arm. While driving one or each of the gears by means of a steering drive element in the same direction of rotation, the positive engagement of the two gears through the pinion and the eccentric mounting of the pinion on the swing arm produce a larger angle of turn of the wheel running inside the turn as compared to the angle of turn of the wheel running at the outside of the turn. To also ensure a steady, flutter-free straight run of the steerable wheels the swing arm end remote from the pinion is adjustable by a selected amount.

Abstract: A device for aligning a pallet or similar article both horizontally and vertically to facilitate a transfer to a support located at a predetermined horizontal position and height comprises first and second banks of engagement rollers which have axes disposed substantially horizontally and which are movable toward and away respective opposite sides of the pallet to engage the pallet underside from each side. In addition, the apparatus includes a vertical alignment member in the form of first and second banks of rollers which extend obliquely and are movable in an oblique plane toward and away from the respective sides of the pallet to engage it at a selected vertical height. The surfaces of the horizontal aligning rollers and vertical aligning rollers engage and support the pallet at a selected intersecting vertical and horizontal plates along its side. The vertical aligning rollers which extend obliquely are advantageously offset from the rollers which have axes which extend horizontally.
