The text and illustrations of US patents are in the public domain unless the patent text contains a specific notice that portions are copyrighted.[1][2] [3] The original patent contains no such notice, so its contents are in the public domain. Note This only applies to images published before March 1, 1989. Patents published after that date are most likely copyrighted, unless PD for another reason, like being uneligible for copyright.
