The Slider Diagram

There are no stop name labels or indications on the stop jambs of this instrument, and there is no immediate indication that there originally were. The diagram above shows the relationships between the drawknobs, the iron slider arms connected to them, and the row of toe holes whose pipes are controlled by the slider underneath the toeboards. The stop names given above are written in ink on the outer side of the right drawknob shanks in handwriting consistent with stop and pitch indications on the wooden pipes. This is likely, but not definitively, the handwriting of the builder, Joseph Downer. The location of his ledger or other written document may confirm this. The left center drawknob's stop indication is based on its connection to one-half of the toeboard otherwise controlled by the drawknob labelled "Open Diapason." The unusual stop designation "Fifth Diapason" is the best reading of the handwriting on the drawknob shank, and may not be correct. To view these stop name markings, please view the Action Image Gallery on the Images: 1788 Organ page.

The Iron Slider Arms

Above are views of the iron slider arms connected to the drawknobs on the left side of the windchest and keydesk. The organ currently rests on a dolly constructed for it decades ago, and is not quite level. Though not all of the connections line up perfectly, the six slider arms (three per side) each fit in only one place. The other slider arms resemble the one on the upper right, without the twist in the vertical shank. These two are shown both as examples and exceptions; the one in the upper and lower left (Left Bottom Drawknob) is the only one that controls two sliders, and its drawknob end is unique. Pictured on the lower right are the those connected to the Center and Top Drawknobs, respectively.
