This patent is held by George W. Parker. While the Stockwell / Parker Photograph Gallery was probably short lived (less
than two years), the partners likely maintained an ongoing business relationship. Stockwell's camera (left) is different
Parker's but the plate changing system matches. It may be that Stockwell only licensed the transfer system for use on
his own camera.
Stockwell View Camera, c.1875 G.W. Parker Camera Attachment Patent
The illustration above shows a sliding-box, fixed bed
camera. It does not match the folding bed, bellows
version by Stockwell but is designed to use the plate
transfer system. The external plate holder is attached
to the body using a pair of hooks.
The plate transfer system illustrated on the second
patent page matches the plate box and dry plate
holder found with the Stockwell camera. Unfortunately
the intermediary transfer mechanism is missing. Plates
are loaded or unloaded by flipping the entire assembly.
The pat'd date on the
plate box is the same
as the patent date.
This would indicate

agreement was in
