I have no idea what this thing is- the only markings on it are Bell System and the date of the patent (I can upload the dates later).
It looks like it would have been used to twist wire or something. Anyone know what this is or what it's called?
Writing on one of the arms is:
PATENTED MAY 14 1919 (could be 1918 or 1913 as well)
DEC 1 1925
