Abstract
Abstract Shuttle box apparatus for decelerating the shuttle of a flyshuttle loom and for reducing impact related noise emanating from such box. The shuttle box includes a shuttle binder and box front wherein at least the binder has internal acoustic damping material providing an impedance mismatch or elastic discontinuity to reduce the transmission of acoustic vibrations through the same and both the binder and the box front have external acoustic damping material on the surfaces which normally are in contact with air for suppressing noise vibrations therefrom.

Claim 1
Independent Claim
250 words
In a shuttle box carried by the lay of a fly-shuttle loom and including a box front with frictional material mounted on one surface thereof, and means for mounting said box front in fixed adjusted position on said lay, the improvement comprising an elongated binder swingably mounted at one end in spaced relationship to said box front, resilient means urging the opposite end of said binder toward said box front, frictional material mounted on said binder on the side facing said box front, a first layer of acoustic vibration absorbing material carried by said binder behind and in engagement with said frictional material, an elongated generally vertically disposed slot extending inwardly frOm the opposite end of said binder more than one-half the length thereof, a second layer of acoustic vibration absorbing material completely filling said slot so that the interfaces between said slot and said second layer are in direct engagement, a third layer of acoustic vibration absorbing material mounted on the side of said binder opposite said frictional material, said first, second and third layers extending the full height of said binder, and a fourth layer of acoustic vibration absorbing material fixed to the upper surface of said binder, whereby said first and second layers of acoustic vibration absorbing material provide an impedence mismatch to resist the transmission of impact related vibrations through said binder and said third and fourth layers of acoustic vibration absorbing material suppress acoustic vibrations which reach the rear and upper surfaces of said binder.
