ABSTRACT:
The invention comprises a two directional cushioning device for towing trailers and the like behind a towing vehicle. The device has a first pair and second pair of parallel rods. The first pair of rods are joined at the outer forward ends for attachment to a towing vehicle. The second pair of parallel rods are joined at the outer rearward end for attachment to a vehicle being towed. The first and second pair of rods are aligned in parallel overlapping relation to one another and are slidably mounted in a pair of caps. One of the caps is adjacent the forward end of the first pair of rods and the other cap is adjacent the rearward end of the second pair of rods. A coil spring is mounted coaxially between the caps urging the caps apart under compression. Nuts are threaded onto the overlapping ends of rods limiting the caps' outward movement relative to one another.
