If your computer doesn't display the drawings of the patent when you click that link (which goes to the page of that patent at the website of the U.S. Patent and Trademark Office), you need to install a plug-in that will enable your web browser to display a TIFF file. Using such a plug-in might increase your web browser's zoom level (its magnification level) to 200% at all webpages (until you reset it to 100%). You can avoid needing to install such a plug-in by going to a search engine such as Google and typing the patent's number (2,253,996) and the word "patent" in the keyword searchbox. This will deliver links to the patent's page at non-governmental patent-search websites. At most of those websites, the images' file format isn't TIFF.

Public domain The text and illustrations of US patents published before March 1, 1989 are in the public domain unless the patent text contains a specific notice that portions are copyrighted. See 37 CFR 1.71(d), 37 CFR 1.84(s)

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 in the public domain for another reason, such as {{PD-ineligible}}.
