Abstract: RIGID INSULATION CORNER FASTENER                          ABSTRACT     The fastener can be made of metal or plastic in the form of a semi-flat disc or plate, with some reinforcing ridges if required.  The disc or plate can be of various geometric shapes and dimension.  At the center of the disc or plate surface is a small hole  for inserting an anchoring screw, nail or bolt.  On the underside of the disc or plate, vertical projections extend downwardly at angular positions corresponding to 0, 90, 180 and optional 270 degrees with respect to the small hole.  The  fastener is placed at the intersecting corners formed by abutting edges of rigid insulation boards, arranged in a "stack" or "running" bond pattern.  The vertical projections of the fastener insert down into the aforementioned intersecting corners.  These vertical projections resist insulation lateral movement or creep after securement of the rigid insulation corner fastener.  The top inserted anchoring screw, nail or bolt is then rotated, driven or tightened into or through the substrate (deck) compressing the rigid insulation between the fastener, and the substrate (deck).  This invention secures surface areas of three or four different adjacent rigid insulation boards with one fastener, depending on the installer selecting a "running" or "stack" bond installation pattern.

The input member is also supported rotatively by bearings (6) which may further include a squeeze film damper (27) to control the assembly spring rate and thereby minimize vibrations by traversing a rigid body mode vibration at low speed.  Such spring clutch assemblies are par-ticularly useful in high RPM environments where vibrations must be held to a minimum.  A clutch spring is also disclosed, having a very fine axial cut across a cross-over coil (41) and transition coils (54) disposed between the teaser coils (52 and the central coils (53).  The transition coils form a gradual ramp (58) to distribute stresses over several coils, preventing spring failure.
