ABSTRACT:
A small wheelable line striper is provided with a gasoline engine powered pump which has an outlet designed for direct immersion into a container of paint or other coating material. The gasoline engine and pump are mounted on a pump frame which is attached to two telescoping posts so that the pump and engine may be lifted upwardly out of the bucket of paint. The pump frame is biased upwardly by a nitrogen gas spring which provides an upward force slightly greater than the weight of the engine and pump so that the pump may be lifted automatically. Latches are provided to latch the pump and engine in either the upward or downward positions.
