USA patent No. 64,892 of 21st May 1867 to be exact although it wasn't the 
familiar full 'figure 8' shape he used.  Two profiled plates, each 
covering six months of the analemma, were fitted into a rotating holder 
to face the Sun in the middle of an equinoctial hour bow.

Picture from the original patent drawing for the curious on request.
