Abstract
A towing apparatus useful for moving mobile homes includes a vehicle having a frame movable to adjusted positions along a linear path of motion parallel to the longitudinal axis of the vehicle, a support mounted on the frame so as to be movable to an adjusted vertical position and a hitching ball mounted on the support so as to be movable in lateral direction with respect to the vehicle to an adjusted position.
Claims9
A combination comprising:
- a towing vehicle having a frame, forward wheels and rear wheels mounted on said frame, said wheel means being adapted to engage the ground;
- a hitching frame mounted on the vehicle so as to be movable from a forward position toward a rearward position with respect to the vehicle along a first path of motion, and first power means connected to the hitching frame for moving it along said first path of motion;
- a support member carried on the hitching frame so as to be movable from a lower position toward an upper position along a linear, generally vertical path of motion, and second power means for moving the support member along said vertical path of motion, independently of the motion of the hitching frame along said first path of motion, the second power means being operative to engage the support member with the ground to raise the rear wheel means above the ground when the forward wheel means are engaged therewith;
- and
- a hitching ball suited for coupling to a second vehicle to be towed by said towing vehicle and means mounting the hitching ball on the support member for motion therewith.

A combination comprising:
- a towing vehicle;
- a hitching frame mounted on said towing vehicle so as to be movable from a forward position toward a rearward position with respect to the vehicle along a first path of motion, and first power means connected to the hitching frame for moving it along said first path of motion:
- guide means mounted on the hitching frame;
- a support member connected to the guide means for vertical motion therealong from a lower position toward an upper position, and second power means for moving the support member along said vertical path of motion, independently of the motion of the hitching frame along said first path of motion;
- an elongated link having one end pivotally connected to the support as the opposite end of the link is being moved by the second power means;
- and
- a hitching ball suited for coupling to a second vehicle to be towed by said towing vehicle, and means mounting the hitching ball on the support member for motion therewith.
