  • Patent number: 4166600
    Abstract: This invention relates to pipe hangers for suspending pipes, ducts and the like from an overhead surface such as a ceiling or a beam, and comprises a metal strip which is bent over at both its extremities and a buckle having a central cut out to receive a threaded rod and said bent-over ends of said metal strip. Nut means are threaded on the rod to clamp all said parts of said hanger together. The buckle may be located above the nut means in the normal position of use of the hanger, and the ends of the strip run up over the top of the buckle on the outside and descend into the central cut-out against the threaded rod and are finally compressed between the buckle and the nut means, whereby the greater the weight of the supported pipe, the greater is the compression exerted by the strip on its own ends via the buckle.
