Adjustable fire sprinkler head support system

An apparatus for three dimensionally supporting a member, comprising:

• a first bracket having a angle-shape including one leg having a first cut-out therein, said first cut-out defining a pair of opposing first ears on opposite sides of said first cut-out, three threaded aperture means in said first bracket and evenly spaced about said first cut-out, one of said aperture means extending through each of said first ears, another leg of said angle-shape having means for fixing said first bracket to an object;
• a second bracket having a second cut-out therein, said second cut-out defining a pair of opposing second ears on opposite sides of said second cut-out, said second bracket further comprising three holes evenly spaced about said second cut-out, one of said three holes being in each of said second ears, and cooperating holes in said second ears for cooperating with fingers projecting from said member;
• three threaded bolts, each said bolt loosely passing through one of said three holes and being threaded in one of said threaded aperture means;
• and
• stop means mounted on each of said three bolts between said first and second brackets, said stop means comprising at least one nut threaded on a respective said bolt,
• whereby said second bracket may pivot about two orthogonal axes and move along a third orthogonal axis relative to said first bracket within limits established by said stop means.

An pipe member in combination with an apparatus for three dimensionally adjustably supporting said pipe member, comprising:

• a first bracket having means for permitting free passage of said pipe member therethrough and three threaded aperture means evenly spaced around said free passage means;
• three evenly circumferentially spaced fingers extending from said pipe member, each of said fingers having a hole therein;
• three threaded bolts, each said bolt loosely passing through one of said holes of said fingers and being threaded in one of said threaded aperture means;
• and
• stop means mounted on each of said three bolts between said first bracket and said fingers,
• whereby said second pipe means may pivot about two orthogonal axes and move along a third orthogonal axis parallel to the length thereof relative to said first bracket within limits established by said stop means.
