Stanley Berkeley, 1855-1909 Englishman
I thought my up-over-the-neck design somewhat unique until I discovered this old illustration in a 19th Century children's book (I don't know the accuracy but the illustration looks convincing). There are however a few flaws in my design; with the flexible poles on my oxcart the three corners of the two-sided triangle are weak, especially the apex.
In the story, the woodcutter has unknowingly given the King a ride into town. Somewhat befuddled, he is returning the guards salute.
