If you look at the entry at the link, it describes it as:
"Design Searches 020109, 020137, 260301 - American Indians. Heads, portraits or busts of men in profile. Ovals as carriers and single line borders."
Multiple designs - "Americans Indian(s). Head(s), portrait(s) or bust(s)..". Seems like at least 3 different ones.
So the 1914 picture above didn't actually get used until late 1930's, as far as I know. The 1913/1914 trademark design is probably this from the 1914 catalog (used as early as 1907, first showing with trademark in 1909?):
In the 1939 catalog you get:
I've also seen early trademarks with screaming Indian but no rifle, and a trademark with a left facing Indian chief (not screaming).
