Mounting for pipes and conduits in studs and joists

Claim 1

For use in mounting a pipe extending through a notch in a stud, in combination, a sheet metal reinforcement of L-shape cross-section having a first and a second flange disposed at right angles to each other and joining at a corner, said first flange formed with a slot extending from its outer edge to said corner, said slot having a keyhole-shape enlargement at said corner and notches formed in said first flange at said keyholeshape enlargement, both said flanges being formed with holes for fastening means to attach said reinforcement to a stud, and a sleeve comprising a cylindrical portion having an outside diameter less than that of said keyhole enlargement and greater than the width of said slot remote from said keyhole enlargement and having a peripheral flange at one end, said cylindrical portion and said peripheral flange formed with a slit to permit said sleeve to be distended and slipped over a pipe prior to assembly of said combination and then moved axially into assembled position with said peripheral flange in contact with said first flange and said cylindrical portion extending from said first flange on the same side of said first flange as said second flange, said sleeve being formed with ears complementary to said notches to locate said sleeve relative to said reinforcement and to restrain movement of said sleeve relative to said reinforcement after assembly, said peripheral flange being truncated at a chordal line aligned with said second flange.
