The records in the U.S. Patent Office are overflowing with wagon-related patents, both applied for and granted. However, by the late teens in the 20th century, a shift was taking place and patent applications were beginning to drop considerably. The automobile had come to stay and its impact could be seen in sales as well as within the increasing lack of patent submissions for wagon parts and designs. Times were certainly changing. Even so, there remained enough uses for - and users of – wood wheeled vehicles that some individuals and businesses were still actively pursuing protection of their related ideas.
While the idea sounds plausible, it would be interesting to see effects of its actual use as well as any data showing the durability and long-term soundness of such a quick fix within challenging terrain. At best, it seems a short term solution that might have additional functionality trials.
That said, some elements of this idea have evolved into successful practices today. In fact, many modern trailers are designed with integrated jacks and separate spare axle spindles – new twists on an old idea. Ultimately, it seems that, no matter the era, the need to be prepared and keep moving forward remains essential to both individual progress and national security.
