Abstract
A hook-type railroad car coupling includes a hook vertically centered and laterally offset in a pocket opening in the front face and a guide pin and hole at opposite top corners. At one side of the bottom a guide horn extends beyond the hook, the front plate having an opening beside the horn and below the hook. A guide wedge is inside the opening to contact the horn of the mating head and improve the parallelism of the front faces of the heads as they come together.
Claims12
A car coupling head with an enlarged gathering zone matable with a substantially identical head on another car comprising the combination of
- a housing having a generally rectangular front plate with a generally flat face and upper and lower horizontal edges;
- means defining a generally rectangular pocket opening through said front plate, the longer dimension of said pocket opening being horizontal;
- a hook pivotally mounted in said housing for movement about a vertical axis,
- said hook extending through said pocket opening and having a portion protruding beyond said front face with a majority of the protruding portion lying to one side of the longitudinal center line of said head;
- a guide member protruding from a first corner of said front plate and means defining a guide hole in a second corner of said front plate to receive the guide member of a mating head, said first and second corners being on substantially the same horizontal line;
- a guide horn mounted near one of said horizontal edges of said front plate and protruding from the face thereof, said guide horn having an inwardly facing surface vertically offset from the closest surface of said hook, said horn being laterally offset from said longitudinal centerline to the other side from said hook;
- means defining an opening adjacent said horn for receiving the horn of a mating head;
- and
- a guide wedge mounted in said housing adjacent an edge of said opening for engaging the horn of a mating head to align the respective flat faces of the heads in parallel relationship,
- said horn including a portion extending into said housing having a curved surface protruding laterally toward said wedge.

- a housing having a generally rectangular front plate with a generally flat face and upper and lower horizontal edges;
- means defining a generally rectangular pocket opening through said front plate, the longer dimension of said pocket opening being horizontal;
- a hook pivotally mounted in said housing for movement about a vertical axis,
- said hook extending through said pocket opening and having a portion protruding beyond said front face with a majority of the protruding portion lying to the right side of the longitudinal center line of said head as viewed from the pivotal mounting of said hook,
- said hook being substantially centered vertically in a horizontal plane bisecting said face of said front plate,
- said hook having a surface which faces to the right as viewed from the pivotal mounting of said hook and includes upper and lower generally planar faces intersecting at about said horizontal plane;
- a guide member protruding from a first corner of said front plate and means defining a guide hole in a second corner of said front plate to receive the guide member of a mating head, said first and second corners being on substantially the same horizontal line;
- a guide horn mounted near one of said horizontal edges of said front plate and protruding from the face thereof, said guide horn having an inwardly facing surface vertically offset from the closest surface of said hook, said horn being laterally offset from said longitudinal centerline to the other side from said hook;
- and
- means defining an opening adjacent said horn for receiving the horn of a mating head, including an inner edge, a first side edge adjacent said horn on said coupling and a second generally vertical side edge generally parallel with said first side edge, said coupling further comprising
- a guide wedge mounted in said housing adjacent said second side edge for engaging the horn of a mating head to align the respective flat faces of the heads in parallel relationship, said guide wedge having an inwardly facing generally vertical surface inclined inwardly away from said second edge,
- said horn including a portion extending into said housing having a curved surface protruding laterally toward said wedge.
