Abstract: A holder for the shank of a tool comprising a cylinder having a series of shoulders and grooves in radial formation with the shoulders and grooves allowing for O-rings to penetrate to the interior and exterior of the cylinder to form a means whereby the shank of a tool can be inserted and the tool held in position. As an alternative embodiment the shoulders and grooves can be helical around the cylinder with rubber latex tubing in the grooves and penetrating to the interior and exterior of the cylinder to thereby hold a tool or implement. Also note that a tool can be inserted at either end of the cylinder; and that an oversize cylinder can be inserted over the cylinder and held by the exterior portion of the O-ring or latex tubing. A special embodiment of this invention is the formation of a grommet employing a tubular portion to form a ring into which is cut grooves forming shoulders and into which is inserted an O-ring to form a grommet.

Abstract: A strengthened masonry reinforcement device is used in construction to strengthen the courses of laid hollow block. The masonry reinforcement device is fashioned with ends and a strengthened trough. When used in the construction of a wall the masonry device with the strengthened trough will be light-weight and retain cement to bind hollow block in a lower course to hollow block of an adjacent upper course.
