Abstract

530,055. Flexible tubes. COLLINS, R. D. June 2, 1939, No. 16327. Drawings to Specification. [Class 99 (ii)] [Also in Groups XXXVI and XXXII] In making an extensible elongated member, such as a flexible-pipe of the kind adapted to gather itself into helical form upon removal of the forces producing extension, the member is first wound into a helix having a certain direction of twist which the member tends to retain indefinitely, after which the member is unwound and then rewound into a helix having an opposite direction of twist, so that the turns of the helix are drawn into close contact with one another by the forces due to the member tending to assume its first direction of twist.
