Abstract
A retractable guide assembly for changing the effective width of a container well of a railroad freight car includes a housing having a pair of spaced apart walls, each having an inverted U-shaped slot, and a guide for slidably mounted between the walls for translational movement relative to the housing. The guide is slidable between a retracted position and an extended position in which a portion of the guide projects beyond the housing. The guide has a bar for extending through each slot of the walls for travelling therealong in a cam relationship as the guide slides between the retracted position and extended position.
Claims11
A retractable guide assembly for changing the effective width of a container well of a railroad freight car, said guide assembly comprising,
- a housing having a pair of spaced apart walls, said walls each having an inverted U-shaped slot,
- a guide movably mounted between said walls, said guide movable between a retracted position and an extended position in which a portion of said guide projects beyond said housing, said guide having a bar for extending through each slot of said walls for travelling therealong in a camming relationship as said guide moves between the retracted position and extended position.
A retractable guide assembly for changing the effective width of a container well of a railroad freight car, said guide assembly comprising,
- a housing having a pair of spaced apart walls, said walls each having an inverted U-shaped slot,
- a guide pivotally mounted between said walls for rotational movement relative to said housing, said guide pivotably between a retracted position and an extended position in which a portion of said guide projects beyond said housing, said guide having a radially extending slot and a bar slidably engaging said radially extending slot for reciprocal movement relative to an axis of rotation of said guide, said bar extending through each of said U-shaped slots of said walls for travelling therealong in a camming relationship,
- wherein said bar is in a radially inward position, said guide is pivotably between said retracted and extended positions and when said bar is in a radially outward position, said guide is restrained in either of the retracted and extended positions.
