Model of a tipping waggon (on a reduced scale). The novelty consists in the three wheels, the locking, the manner of tipping, the form, the concentration of the weight or load upon one axletree near to the horses' shoulders, and its adaptation to single or double shafts. It may be used as a two-wheel cart, by removing the hind carriage-work .
