Abstract: A pair of arms are pivotally connected with each arm including a hand grip portion and a ball clamping portion. The clamping portions carry ball support members which support and center a ball within the tester. A gauge is mounted on one of the clamping portions and has a plunger which extends through one of the ball support members for engaging the outer surface of a ball. Movement of the clamping portions is limited by engagement of the end surfaces of the clamping portions. A torsion spring normally urges the hand grip portions away from one another. In one embodiment, the spring urges the clamping portions toward one another, and in another embodiment, the spring urges the clamping portions away from one another.

Abstract: An insulating roof system for manufactured homes and similar commercial structures including a base comprised of a single metal roof supported by sidewalls and an interior framing member beneath the base perimeter and having a weatherproofed vapor barrier which supports a layer of flexible insulation and a non-insulating rigid support means which bounds the layer of flexible insulation and houses a plurality of insulation vents which permit the escape of vapor pressure resident within the flexible insulation. A weatherproof membrane is disposed upon the layer of flexible insulation and is supported by the non-insulating rigid support means. A plurality of rigid insulation supports are mounted about roof penetrations and the weatherproof membrane is secured by a mesh strap means disposed over the membrane with a plurality of terminal ends double sealed and secured to the interior framing member by a rust resistant fastening means.
