  • Patent number: 5209096
    Abstract: An improved sheet metal brake is disclosed. In the preferred embodiment, the invention basically comprises an elongated rod which attaches to an existing pivotable brake lever. With this extension attached to the brake lever, a user can move the lever extension back-and-forth to open and close the brake. Because the user can now stand in the center of the sheet metal, he can use his body weight to press against the sheet metal to further secure it. This prevents the sheet metal from slipping. As a result, the sheet metal is not bent off-line.

  • Patent number: 4883145
    Abstract: A simple apparatus is disclosed that reduces the risk of low-back injury to workers in elevated, partially enclosed, aerial baskets. The preferred embodiment basically comprises a circular well within the floor of the basket that is surrounded by a raised footrest platform adapted to receive on foot of the worker. Between the footrest platform and a base of the well is a cylindrical wall that prohibits forward movement under the footrest platform.In operations, when the worker has to perform manual handling tasks outboard of the basket, one foot is raised out of the well and extended forward onto the footrest platform, while the other foot remains below and behind the raised foot, on the base of the well. The worker has thereby adopted a forward leaning posture instead of a forward bending posture. Consequently, the worker retains the optimal curvature of the spine, while achieving a biomechanical advantage that reduces the work demand on the lower back.

  • Patent number: 4680571
    Abstract: An alarm system is disclosed for warning personnel at a loading dock that a trailer being loaded has crept away from the dock. In a preferred embodiment, the alarm comprises a box-like housing that can be bolted onto the dock; a clamp that is magnetically held against the outside of the housing and which can be removed for quick attachment to a nearby trailer; and, a spring-loaded cord that is spool fed from inside the housing and connected to the clamp. After the clamp has been attached to the trailer, the alarm automatically arms itself through the use of a novel timing mechanism and spring-loaded actuating arm inside the housing. If the trailer then creeps, it tugs the cord, which causes the arm to trigger the alarm. The alarm stays on but can be automatically shut off by simply replacing the clamp back onto the housing.
