[Roller-skate patents]
A United States Patent Office compilation of roller-skate patents issued around 1861, published in Washington, D.C., for inventors and patent examiners. The pictures are engineering line drawings of wheel assemblies, frames and mounts with lettered reference marks, showing how early skate designers arranged wheels beneath a foot platform. A designer might draw on their clean mechanical diagram style and their simple, legible hatching for technical or retro illustration work.
