1882 Bicycle Patent of Thomas B. Jeffery


TBJ in this design includes a precision headset, the clincher tire patent, a headless spoke design, and some redesign improvements on pedal mechanisms, all on the same patent.

It is interesting to note that although Jeffery spent years as a model maker, constructing models for others to submit with their patent applications, Jeffery here chose not to include a model of his own patent application.
