Abstract

A snake which can be power driven through a clutch or manually rotated with a crank. The coiled wire body terminates in a nose cylinder which has coils which are of a larger diameter, constant diameter, and expanded terminating in a cylinder snag tip cut-off co-extensive with the circumference of the expanded cylinder wire portions. A cap is provided over the sheath which surrounds the coiled wire at each end of the sheath, and having progressively smaller interior collar members terminating in a cap lip which permits the cap to snug-fittingly and progressively engage the end of the sheath, and yet permit it to be removed after usage so that the interior of the sheath can be flushed and when desired, filled with lubricating oil or another preservative. The method of the invention is directed to the utilization of a coiling head which coils the wire in a small diameter and then increases the diameter to form the nose cylinder. The nose cylinder is first formed in its compressed form at slightly more than its intended length. Thereafter the compressed cylinder is opened by applying tension at both ends to expose an expanded cylinder. Thereafter a cylinder cut-off portion or cylinder tail is removed and the operation progressively repeated.
