Ballpoint pen patentIn 1888, the first U.S. patent for a ballpoint pen was issued to John J. Loud of Weymouth, Mass. (No. 392,046). This patent described a pen having a spheroidal marking point capable of revolving in all directions which was held down by three smaller anti-friction balls, themselves held down by a flaired spring-loaded rod. A threaded cap at the end of the pen could be removed to recharge the pen with ink. The patent described the invention as being especially useful for the marking of rough surfaces such as wooden or paper boxes, coarse wrapping paper and other surfaces where the ordinary nib of a fountain pen could not be used because it would split, spatter or catch. |
