Ball type gooseneck hitch

In combination,

• a wheeled vehicle having forward and rearward ends, said wheeled vehicle having a support member at the forward end thereof,
• a hitch means secured to said support member for coupling connection to a prime mover having an upstanding coupler ball mounted thereon,
• said hitch means comprising a substantially horizontally disposed support member having a coupler mounted thereon which extends upwardly therefrom and which has an open lower end, said coupler adapted to receive the coupler ball therein,
• a slide member slidably mounted below said support member and being movable between forward, intermediate and rearward positions relative to said coupler,
• a locking means mounted on said support member and being movable between locked and unlocked positions,
• said slide member, when in its said forward position, having a forward end disposed beneath said coupler lower end so that said forward end will maintain said coupler ball in said coupler,
• said slide member, when in its said rearward position, permitting said coupler ball to move upwardly into said coupler,
• said slide member, when in its said intermediate position, being positioned intermediate said forward and rearward positions,
• said locking means engaging said slide member and maintaining said slide member in said forward position when said locking means is in said locked position and permitting said slide member to move rearwardly from said forward position when said locking means is in said unlocked position so that engagement of the coupler ball with said slide member during the coupling operation will cause said slide member to move rearwardly from its forward and intermediate positions to expose the lower end of said coupler and permit the coupler ball to move thereinto,
• actuator means connected to said locking means and acting on said slide member through said locking means to yieldably maintain said slide member in its said intermediate position when said locking means is in said unlocked position.
• said actuator means acting on said locking means and acting on said slide member through said locking means to automatically move said locking means to said locked position and to automatically move said slide member to said forward position after said coupler ball has moved into said coupler.

In combination,

• a wheeled vehicle having forward and rearward ends, said wheeled vehicle having a support member at the forward end thereof,
• a hitch means secured to said support member,
• a prime mover having an upstanding coupler ball mounted thereon for coupling connection to said hitch means,
• said hitch means comprising a substantially horizontally disposed support member, a coupler mounted on said support member and extending upwardly therefrom and having an open lower end, said coupler adapted to receive the coupler ball therein,
• a slide member slidably mounted below said support member and
• being movable between forward, intermediate and rearward positions relative to said support member,
• a shaft operatively rotatably mounted on said support member rearwardly of said slide member and being disposed transversely with respect to said slide member,
• said shaft being selectively movable between first, second and third rotational positions, said shaft being normally positioned in said first position,
• said shaft having an actuator element mounted thereon for rotation therewith, said actuator element being offset with respect to the rotational axis of said shaft,
• said actuator element being positioned between said shaft and the rearward end of said slide member when said shaft is in its first position to prevent the rearward movement of said slide member thereby maintaining the coupler ball in said coupler,
• said actuator element being positioned below the axis of said shaft when said shaft is in its third position to permit said slide member to move rearwardly to expose the lower end of said coupler,
• means for selectively maintaining said shaft in its said second position during the initial stages of the coupling operation whereby engagement of the coupler ball with the forward end of said slide member will move said slide member rearwardly and rotate said shaft from its second position to its third position, and means for automatically returning said shaft to its first position after said coupler ball has moved into said coupler.

Apparatus for hitching a trailing vehicle to a towing vehicle, said towing vehicle having an upstanding coupler ball adjacent its rear end, said apparatus comprising a substantially horizontally disposed support member adapted for attachment to the forward end portion of the trailing vehicle, a coupler on said support member and defining a downwardly opening socket adapted to receive said ball, a slide mounted on said support member beneath said socket to move between a forward coupling position and a rearward released position, said slide, when in said release position, being located rearwardly of said socket in a position to permit said ball to enter said socket and, when in said coupling position, engaging said ball to retain the ball in said socket, locking means mounted on said support member to move between locked and unlocked positions and being operable when in said locked position to hold said slide forwardly in said coupling position, said locking means being operable when in said unlocked position to permit said slide to move rearwardly to said released position, said locking means engaging said slide and moving the slide from said released position to said coupling position when the slide is in said released position and said locking means is moved from said unlocked position to said locked position, resilient means connected between said locking means and said support member and urging said locking means toward said locked position, and means for releasably holding said locking means in said unlocked position against the action of said resilient means and operable in response to rearward movement of said slide to said released position to automatically release said locking means for movement to said locked position under the urging of said resilient means whereby said locking means moves said slide forwardly to said coupling position.
