Abstract
118,860. Calthrop, E. R. June 12, 1917. Addition to 8649/15. Helical springs; india-rubber springs.-In parachute suspension ropes having a spring device interposed as described in the parent Specification, the rubber strands forming the spring device are twisted together in opposing spirals. Fig. 3 shows the spring device comprising two opposite spirals 3 of rubber strands a - - c arranged so that the outermcst strand a at the top is the innermost strand at the bottom, so that the strands are of equal length; the left-hand spiral is shown slightly untwisted at the ends. In a modification, Fig. 5, two series of strands are arranged in opposing spirals between metal caps 19.
