Have y'all read the very-detailed Description text in the Patent-Application? I'm asking because the posted diagram is incomplete (it is missing "Figure 3", which kinda-sorta indicates y'all may not have seen everything there is to see in that patent. In its text, the inventor explains how his invention is an "improvement" over existing buttons.

One significant difference between this patented 1923 button and its 19th-century ancestors is that it is made of stamped 1-piece aluminum. Until the very-late 19th-century, aluminum was an extremely rare and valuable metal ...in fact, priced higher than gold.

Despite this inventor's many claims of "improvement, I see only two other significant differences between typical 19th-century 4-hole buttons and his 1923 "improvement" of them. His button's holed area (which he calls the "web") is thicker, and the holes in it are beveled at their top and bottom (to prevent a hole's sharp edges from cutting the mounting-thread). Those two features are visible in his patent-diagram's Figure 3 ...which is absent from the .jpg posted by BCH.

Wow thanks CBG. I started reading it and got frustrated. I thought maybe he took a patented English button and patented it in the USA but it is thicker. I had to crop the pic years back because I havent figured out how to copy it. I use "print screen" and my screen isnt large enough for the whole patent unless I reduce it in size.

Thought you'd want to know... the dug ones I have seen (in person) have the corrosion-characteristics of Zinc.
