Based on the title and the filing date we must assume that this patent is a descendant of Patent US-1913-1087946. As is the case with many patents filed in Spain, Espacenet lacks the original document. We have quite minimal data here. This is of fairly strictly of "familial" interest. As always, with Spanish patent data on Espacenet, alleged "priority date" data in the inventors name-based search results column is actually the filing date of of the Spanish patent, not the actual priority date.
