  • Patent number: 4350363
    Abstract: A stop assembly (66) for a bail (20) is provided which is particularly useful with the bail (20) of a push-pull scraper (18). The bail (20) is pivotally mounted by a pair of bifurcated brackets (28,30) affixed to the scraper (18), and is normally raised and lowered by a fluid cylinder (38). When the bail (20) is raised, if not positively stopped from further raising, the fluid cylinder could bottom-out or be otherwise damaged. The stop assembly (66) comprises a fixed pin (68) mounted within the bracket (28) in proximity to a pivotal eye portion (22) of the bail (20), and a first surface (76) on the eye portion (22) which engages with the pin (68) when the bail (20) is in a raised position. Engagement of the first surface (76) with the pin (68) stops the bail (20) from being further raised, and protects the fluid cylinder (28) from damage.

  • Patent number: 3967695
    Abstract: A yieldable vehicle step is provided having a rigid foot support member pendantly supported from the side of a vehicle frame by a pair of relatively strong, but deflectable legs. Each leg is constructed from a chain and an outer deformable stiffener member circumposed about such chain. The outer member affords sufficient lateral rigidity or stiffness to the legs so as to minimize undue swinging movement of the step when in use, but which automatically returns to its suspended position whenever deflected by contact with an obstruction during movement of the vehicle.
