Abstract: A method and apparatus for forming a metal housing, such as a blower housing, by successively securing a wrap panel to spaced-apart end panels by a series of welds. The end panels are rotated through a series of steps by a work-holding subassembly while a pair of primary welder subassemblies reciprocate in a linear path through a plurality of weld positions and apply a plurality of spot welds to the circumference of the generally circular end panels joining the end panels to the wrap panel. A panel advancing subassembly pushes a rear end of the wrap panel to assist the forward wrapping movement of the wrap panel around the end panels A pair of secondary welder subassemblies, each having a pinch gun welder, move horizontally along another linear path and perform a plurality of welds along a linear lip of the blower housing. The primary welder subassemblies are then indexed horizontally along another linear path to perform spot welds along a linear aligned section of the blower housing.

Abstract: A lawn edger wheel mechanism for laterally shifting a front wheel to clear an adjustable cutting blade of the lawn edger comprises a latched detent member defining a plurality of lateral wheel positions. The wheel can be laterally guided on a carrier located by a transverse support shaft, the carrier being prevented from rotating about the shaft by engagement with the detent member, the detent member being formed on a cross member of a base of the lawn edger. A lever, pivotably mounted to the base can engage a bearing member located on the carrier between the support shaft and the detent member for convenient lateral movement of the wheel without binding of the carrier.
