US 5,632,583 A · Split bolt ring

Abstract

An apparatus formed from a base member and a plurality of bolts is used to position the bolts on a flange. The base member is preferably arcuately shaped and has a first end and a second end. The arcuate base member defines a plane and is hand bendable in the plane. The base member has a longitudinal axis normal to the plane and a radius of curvature with respect to the longitudinal axis. A plurality of bolts are mounted to the arcuate base member. Each bolt of the plurality of bolts extends generally longitudinally from the arcuate base member. The device is useful for mounting items to a flange. A multiplicity of boreholes extend through the flange in a direction generally parallel to the longitudinal axis of the tubular member from the back face to the front face. Each borehole is defined by a borehole wall. The bolts are retained in frictional engagement with the borehole walls due to tension from the arcuate base member.

Apparatus comprising:

an arcuate base member having a first end and a second end, said arcuate base member defining a plane and being hand-bendable in said plane, said arcuate base member having a longitudinal axis normal to the plane and a radius of curvature with respect to the longitudinal axis said arcuate base member further having a rectangular cross section having a major axis and a minor axis, wherein said major axis is parallel to the longitudinal axis of said arcuate base member, said arcuate base member spans an arc having an angle in the range of about 60 degrees to about 180 degrees, said arcuate base member has a first radius of curvature at a mid portion of the arcuate base member and a second radius of curvature which is greater than the first radius of curvature at the first end and the second end;
and
a plurality of bolts mounted to the arcuate base member, each bolt of the plurality extending generally longitudinally from the arcuate base member in a first direction.
