Patent number: 9242588Abstract: A tow bar for selectively securing a pivotable container assembly of a dump cart includes a tow bar rotatably connected to a frame of the container assembly. A latch is adjacent to a receiving surface of the tow bar, and includes a slidable member, a biasing element and a lever. The slidable member is configured to selectively engage an arm which extends from the container assembly and for latching the container assembly in a loading condition. The biasing element is configured to urge the slidable member into engagement with the arm. The lever is coupled to the tow bar, slidably coupled to the slidable member and includes an actuation plate spaced apart from the receiving surface. When actuated, the lever moves the actuation plate toward the receiving surface and urges the slidable member away from the arm, enabling release of the engaged arm from the tow bar.Type: GrantFiled: June 9, 2015Date of Patent: January 26, 2016Assignee: OHIO STEEL INDUSTRIES, INC.Inventors: Thomas P.

Patent number: 4968096Abstract: A cargo-receiving bed is pivotally mounted upon a wheeled undercarriage. An elongated actuator is telescopically and slidably mounted in the undercarriage and is hitched at its free end to a tractor. A lifting mechanism is connected to a portion of the actuator extending into the undercarriage to raise and lower the cargo bed. In one embodiment, the lifting mechanism comprises a pair of jointed arms each connected at one end to the cargo bed and at the other to the actuator. Suitable stop and guide members are provided to urge the arms into elevated positions as the actuator moves into the undercarriage and lowered positions as the actuator moves out of the undercarriage. An alternative lifting mechanism includes a lifting cam and a series of pivotally connected rods. Inward movement of the actuator causes the cam lifting surface to rotate upwardly against the underside of the cargo bed.Type: GrantFiled: October 13, 1988Date of Patent: November 6, 1990Assignee: Ohio Steel Industries, Inc.Inventor: Elmer J.
