Abstract
Abstract The shuttle contacting wear faces of a shuttle checking mechanism are covered or lined with a textile laminate which exhibits the feel, flexibility and shock-resistant qualities of leather and far exceeds leather in resisting wear. The lining material consists of multiple layers of woven fabric of a highly wear-resistant type, laminated and bonded with a rubber-like compound which contains heat dissipating material. The exterior friction face of the lining material may also be coated with an additional heat dispersing and radiating composition and such face may also be embossed to further reduce friction and resultant heat build-up.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
113 words
In a loom, a shuttle checking mechanism including parts which are engaged by the moving shuttle for the purpose of checking the flight of the shuttle and said parts having working faces, and a friction lining for said working faces, said lining consisting of multiple woven fabric layers having a canvas-type weave and having a weight of approximately 1 1/2 pounds per yard, said woven fabric layers being bonded together and impregnated with a low viscosity rubber impregnant having Heat dissipating material dispersed therethrough in the form of fine aluminum particles, said impregnant saturating and bonding said woven fabric layers into a substantially homogenous mass which is flexible and extremely tough and wear-resistant.
Claim 2
Dependent Claim
