Lillie Eginton Warren. Means for Teaching Reading of the Facial Expressions which Occur in Speaking.
US Patent 726,484, April 28, 1903
available also via espacenet here (and of course via USPTO).
I surmise that the facial expressions illustrated in the patent document, from which the animated gif is formed, are taken from photographs, perhaps of Warren herself. They “may represent a variety of letters or combination of letters,” she writes, to distinguish her idea from prior art.
Those letters/combinations of letters — sounds, really — are:
01 w, wh, long and short oo
02 y, long e, short i
03 broad a i e ah, and short o
04 f, v
06 sh, soft ch, soft g, and j
07 p, b, m
10 r, ur, and short u
12 t, d
13 short a, short e
14 k, hard g, and ng
15a long a
15b long a
16 s, z
The animated gif runs through these expressions in order. Another animation might be prepared to demonstrate the collocation of expressions used to form Warren’s example sentence —
