Patent ID: 6837486

Claim:
A method for feeding an elongated flexible cable into a pipe having a pipe end and a pipe wall defining an elongated pipe passageway having a passageway longitudinal axis, the method comprising: taking a frame assembly comprising a shoe frame connected to a roller frame, the shoe frame having an inflatable bladder capable of being inflated from a collapsed condition to an inflated condition, the shoe frame being sized to fit loosely within the pipe passageway when the bladder is in the collapsed condition and to be tightly retentively held within the pipe passageway when the bladder is in the inflated condition, the roller frame having a roller mounted thereon for rotation about a roller axis; inserting the shoe frame into the pipe passageway through the pipe end to an inserted position wherein the shoe frame is at least partially within the pipe passageway and the roller frame and the roller are positioned outside the pipe; inflating the bladder to the inflated condition whereby the shoe frame and the bladder retentively engage the pipe walls and hold the shoe frame and the roller frame against movement relative to the pipe; feeding the elongated flexible cable around the roller and into the passageway whereby the flexible cable has a first segment on one side of the roller and outside the pipe passageway, and a second cable segment on the opposite side of the roller within the pipe passageway; the shoe frame including a first removable section having a first size; removing the first removable section when the first size does not fit a cross sectional size of the pipe passageway; and replacing the first removable section with a second removable section having a second size that fits the cross sectional size of the pipe passageway.
