ABSTRACT:
A mechanical or attachment holder and support means for securing a spline driven in a groove for holding down a flexible sheet or filter screen under continually changing temperatures and high pressures comprises, a plurality of 90.degree. angle clips in axial alignment on the spline extending around the periphery of the filter screen with one leg of the clip pressing the spline down and the clip other leg being positioned against a longer side of the groove, and screw inserted through the 90.degree. clip bisecting the 90.degree. angle between of the clip legs for securely fastening the spline and the filter screen under the spline securely to a filter screen holder for resisting the environmental conditions of continually changing temperatures between 200.degree. and 250.degree. F. under a minimum pressure of 200 psi for thus increasing the service life of the filter screen securing means or holder and support, for increasing run operating time on the filter screen, for decreasing filter screen maintenance, and for retaining the spline in the groove for the life of the spline.
