[HM] old teaching tool

A while ago I came across a list created in 1841, by a Professor Haskell
listing apparatuses in use in New York schools Among the items in his list
was "The machine to illustrate angles, chords, sines, tangents, etc." The
language used made me think there was some common apparatus that was used
for this purpose, but I have not been able to find any description or
illustration of such an object. Can anyone suggest what such a machine was,
or where I might find information about one?

My thanks for any contribution.
