Abstract
An elongated shower pipe, extending across a paper stock treatment machine, such as a Fourdrinier, instead of being a uniformly simply supported span, is supported on brackets at each end designed to significantly reduce the deflection of the shower pipe. The brackets include fixed supports inboard of the ends and deflection means, outboard of the supports, which apply a moment of force in a direction opposite to the forces exerted by the gravity on the central span of the pipe. Threaded means adjusts the amount of anti-sag force.
Claims4
Anti-sag apparatus for elongated shower pipes of the type extending across a paper stock treatment machine said apparatus comprising:
- an elongated pipe of predetermined length and diameter having opposite ends;
- a pair of brackets, each fixed under one of said ends and each having a support means thereon, fixed at a predetermined distance inboard of said end for supporting said pipe against downward movement and
- each said bracket having downward deflection means, located at a predetermined distance outboard of one of said support means for holding down the adjacent end of said pipe
- whereby the portion of said pipe, between said brackets, may be free of braces, tie rods and reinforcing structures, supported against sag and of a diameter and thickness required for hydraulic capacity rather than for structural stiffness.
