Abstract: A mount for traveling within a pipe to center a tool, such as a camera, within the pipe. Inner and outer concentric cylinders are slidably nested. Pivoted leg pairs have one end connected to the outer cylinder and another end connected to the inner cylinder. The pivoted leg pairs move radially inward or outward as the inner and outer cylinder move axially with respect to each other. A spring biases wheels attached to the distal end of the pivoted leg pairs radially outward. The mount centers the inner and outer cylinder within the pipe and automatically adjusts to different diameters of pipes. The mount overcomes obstructions within the pipe and is easily retrievable. The interior of the pipe may be inspected or worked upon.
