Abstract: A tooth adapter having an elastomeric clamp assembly and a method for using the same are provided. The system includes a tooth adapter having a first end operable to receive a removable tooth point and a second end having an upper blade and a lower blade, the upper and lower blades at least partially defining a cavity configured to receive a tooth horn. An upper insert is configured to be disposed at least partially within an orifice in the upper blade, and a lower insert is configured to be disposed at least partially within an orifice in the lower blade.

Abstract: An adapter assembly which includes an adapter having first and second adapter ends and first and second adapter sides. A removable tooth having first and second tooth sides is coupled with the adapter, and at least partially covers the first adapter end. A retainer pin extends at least partially through first and second openings of the first and second tooth sides, respectively and through an elongate slot of the adapter. The retainer pin is operable to cooperate with the adapter adjacent the first and second openings to couple the removable tooth and the adapter. A secondary retainer pin extends from the adapter at least partially into the elongate slot and engages a recessed portion of the retainer pin, the secondary retainer pin being operable to limit movement of the retainer pin along an imaginary longitudinal axis of the elongate slot.

Abstract: A lock member for a Type E railway freight car coupler formed of an as-cast and austempered ductile iron casting, having a slightly over-sized head portion, the as-cast and austempered ductile iron casting having a minimum tensile strength of about 140 ksi, a minimum yield strength of about 110 ksi, a minimum elongation in 2 inches of about 4%, and a BHN of about 321-388.

Abstract: An elongated light-weight, cast draft sill mountable at the end of a center sill of a railway car body, and to which a railway car truck is pivotally mountable, the cast draft sill having a generally hollow, elongated rectangular body, with a pair of elongated, parallel side walls extending perpendicularly from an elongated top wall and further including a draft pocket adjacent to the forward end adapted to receive a coupler yoke and associated draft gear, and a light weight center plate portion which is mateable to a railway car truck spaced from the rearward end of the cast draft sill.

Abstract: A non-binding, slack-adjusting, gravity wedge member for use in a railway slackless drawbar system, the wedge member having a pair of opposed friction faces at an inclined angle to each other, with a first of the faces having at least one recess therein adapted to receive an elastomeric body bonded therein such that an outer, flat surface of the elastomeric body is exposed and spaced outwardly from and parallel to the first face, such that the elastomeric body has an exposed outer flat surface of at least about 35 square inches, and a hardness of at least about 50 durometers.
