Abstract: A well casing security device and method. The security device includes a cover including a sidewall, a top, one or more stabilizers, and a means for attaching the cover to a well casing or to its concrete slab to render it vandal-resistant. A locking support ring is provided for attachment to either the well casing or to the concrete slab surrounding the casing. The locking support ring includes a ring body with a plurality of braces. Each of the braces includes an arm defining a slot between the arm and the ring body. The cover includes a plurality of brackets enabling rotational engagement cover with the locking support ring. Locking means are provided on the cover to lock the cover to the locking support ring. The locking means includes a key operated lock that is tamper resistant and insures that the well casing cannot be accessed easily by an intruder.

Abstract: A removable safety system for construction workers which is mounted on an I-beam to provide a cable hand hold to which a safety lanyard may be fastened. The system includes a cable tensioner and shock absorber assembly that is utilized to pretension the cable and absorb shock in the event a worker fastened thereto inadvertently falls.

Abstract: The specification discloses a removable safety system for construction workers which is mounted on an I beam which provides a cable hand hold to which a safety lanyard may be fastened. The ends of the cable are terminated by a special device that increases the grip of the device on the beam when a load is applied.The safety system may be installed on the I beam at ground level and hoisted with the I beam as it is positioned for attachment to a building or bridge.

Abstract: A safety post for construction workers and the like comprising angle structure having integral horizontal and vertical legs, the horizontal leg having a clamp including fixed and movable tapered members opposed on the underside of the horizontal leg for detachably gripping structural beams, the movable member having a portion loosely encircling the horizontal leg with a fulcrum below and screw structure operable from above to pivot and tighten the movable member; the vertical member having a column which may optionally be height-adjustable by telescoping of separate lengths, and which terminates at the top in a pair of fixed arcuate horns with the ends inward turned and overlappingly spaced for retaining a safety cable therebetween while permitting workmen to walk their safety lines along the cable without need to unsnap the safety lines at the safety post.
