Latest Patents

One of McLean's notable inventions is the Adjustable Grab Iron. This invention relates to grab irons and is particularly designed as a two-piece, adjustable grab iron. The grab iron consists of a handhold-shape containing a mounting flange portion and a rod member, as well as a grabfoot-shape containing a mounting flange portion and a base portion with a ring that has a hole sized to receive the rod member of the handhold-shape. The rod member features a series of holes spaced along its length, formed at the same angle as measured from a horizontal vector. The base portion includes a single pin hole that allows alignment with any of the pin holes in the rod member. The two pieces are secured together using a metal fastener, such as a steel expansion pin or a screw. The design ensures a secure fit between the rod member and the base portion ring.

Another significant invention by McLean is the Uncoupling Device for Rotary Couplers on Freight Cars. This device includes a bail that is rotatably mounted adjacent to the open end of the car center sill. The bail can be selectively swung from a rest position to an action position, making contact with a rotor element on the locklift assembly linkage of the coupler. An operating rod, which is rotatably mounted on the end of the car, is interconnected through a mechanical linkage arrangement to the bail. By manually turning this rod from the side of the car, a mechanical advantage is achieved, allowing force to be applied through the bail against the rotor element to open the knuckle of the coupler.
