Abstract
Connecting devices for assembling the ends of helical springs with respect to other members wherein each connecting device includes at least two elastic branches adapted to frictionally engage with the end coils of a helical spring to thereby prevent the resonance of the spring when it is subjected to extension and compression. The connecting devices are particularly adapted for use for damping springs associated with the heddles in a weaving loom.
Claims15
A connecting device for dampening resonance of a helical spring which includes coils defined by an inner diameter and an outer diameter which coils are alternatively extended and compressed relative to one another and wherein the spring includes a remote end secured to a first spaced member and a free end, the connecting device comprising, a body having a threaded portion adapted to be threadingly received with the free end of the spring and a spaced end portion adapted to be engageable with a second spaced member, at least two elastic branches extending from said body which are elastically movable with respect to one another along at least a portion of their length, said at least two elastic branches being oriented relative to said threaded portion so as to be adapted to frictionally engage the coils of the spring to thereby prevent resonance of the spring when said threaded portion is received within the coils of the spring.
In a weaving loom having a harness system including a oscillating heddle connected to a spring wherein the spring includes coils defined by an inner diameter and an outer diameter which coils are alternately extended and compressed upon the oscillating movement of the heddle and wherein the spring includes an end secured to the heddle and a free end, the improvement comprising, a connecting device including a body having a threaded portion adapted to be threadingly received within the free end of the spring and a spaced end portion adapted to be engageable with a spaced member associated with the weaving loom, at least two elastic branches extending from said body which are elastically movable with respect to one another and which are spaced with respect to one another along at least a portion of their length, said at least two elastic branches being frictionally engaged with the coils of the spring to thereby prevent resonance of the spring during the oscillating movement of the heddle.
