Abstract: A machine for producing a corrugated wheel spacer for use between tandem truck wheels includes top and bottom corrugated rollers which are driven in synchronism with an annular spacer blank therebetween to corrugate the blank. The top roller is suspended from a carriage for vertical movement towards and away from the bottom roller so that an annular blank can be placed on the bottom roller when the rollers are spaced apart and the rollers can be moved together to effect a corrugating operation.

Abstract: Conventional wheelbarrow are difficult to steer, particularly when fully loaded. The wheelbarrow of the present invention provides a simple solution to this problem. The wheelbarrow includes a pair of L-shaped axles carrying wheels (or skis for winter use) rotatably mounted in vertical sleeves on the frame of the wheelbarrow. A crossbar on the front end of a pair of handles carries a shaft rotatable in cylindrical bushings on the frame. A linkage connects the front end of the shaft to levers on the vertical arms of the axles, so that rotation of the handles results in rotation of the shaft and consequently rotation of the axles and wheels around the vertical axes of the vertical arms of the sleeves to steer the wheelbarrow.
