Abstract: A trash compactor formed of a box-like body mounted upon wheels to provide a trailer for towing by a vehicle. The body forward and rear ends are open and doors cover each end, with each door being pivotally mounted at its upper end for swinging forwardly and rearwardly. The forward door swings interiorly of the body, as well as forwardly. The body floor is formed with an arcuate shaped portion corresponding to the path of swinging movement of the lower end of the forward door and then with a downwardly sloped portion extending to the rear opening. Trash may be deposited upon the arcuate floor portion and from time to time swept rearwardly and compressed by the interior swinging of the forward door and then stored in the sloped floor area of the body for later dumping by opening the rear door.
