1872 · U.S. PATENT RECORD AS REACHED · CROSS-REFERENCE ARTICLE
The solar-camera patent the floor names (holders Dille, Poston) is verified as a transaction — in Fort Wayne. The Fort Wayne directory record states it in one sentence: in 1872 Elisha W. Poston and his partner (the Dille of the floor, a Fort Wayne photographer then listing himself as a "solar photographer" at 44 Calhoun) sold a patent in "improvement in solar-cameras" to John A. Shoaff. That is the trade's patent record as the open sources give it: Allen County men, an Allen County buyer, an 1872 sale. No solar-camera patent, and no photographer-inventor of any other pattern, was found in the St. Joseph County record reached, and no Osceola inventor-photographer exists in any record reached — the town's patent record belongs to its inventors leg, to which this article cross-references the whole class, per the row's own direction ("cross-referenced to the inventors leg, not retold"). What this section prints is therefore the correction and the pointer: the Dille/Poston/Shoaff patent must not be seated in South Bend or Osceola in any assembled text; a reader who meets it in the checklist pattern should find it filed under Fort Wayne, where the directory puts it.
