FABRIC FOB GASKETS. Application filed September 9, 1921. Serial Ito. 499,558.

My invention relates to gaskets or similar increase the tensile strength of the asbestos packing s' adapted to withstand relatively strands and prevent their fraying upon the high temperatures and pressures, and to surface and produce a woven fabric of great fabrics of which such gaskets or similar uniformity of thickness, packings may be made. "lhewoven fabric may be" cut into gaskets so In the preferred form of my invention the of any desired shape and when so cut will asket or similar packing is made of a fabric not fray along the edges and will there- 'which comprises a woven material composed fore require no binding at thejedges and of asbestos or other heat-resisting fiber will be stiff enough to hold their shape when wound about a @re of lead or otherreadily cut in complicated forms. By suitably e5 deformable wire interwoven with cross wires choosing the weave with respect to the presof a suitable metal, the choice of which desures to be encountered, the gasket thus pends upon the use to which the gasket is formed will resist blowing out in narrow to be put. In this construction the strands sections to a high degree.
