HENRY CLAY CAMERA
HINGED-BED DESIGN WITH MATHEIN SHUTTER
American
Optical Company, Scovill & Adams, Proprietors 1893 - 1897
This second
version of the Henry Clay Camera now
incorporates a hinged-bed design, which is found on most
surviving examples of the Henry Clay.
The example shown here is equipped with a Mathein (or Wale & Mathein) Shutter,
which became standard issue for the Henry Clay by at least late 1893. This is reflected in an ad engraving from
Scovill & Adams' The American
Annual of Photography and Photographic Times Almanac for 1894, copyrighted
1893:
Prior to this, an ad engraving in Scovill & Adams' How to Make Photographs, October, 1893,
depicts the Henry Clay with Scovill's
Instantaneous Lens and Shutter:
Although Scovill is carrying forward their generic
wording with both advertisements stating "5x7
Henry Clay Camera complete, with Instantaneous Lens and Plain Shutter",
the two shutters are of distinctly different designs, each covered by its own
patent:

The date range cited for this Henry Clay Camera is 1893-1897,
as by 1897 or 1898, the last version of the Henry Clay is introduced with a
slightly more compact body. The
dimensions of the camera shown here are 8-1/4" in height, 6-1/4"
depth and 9" width, whereas the last model's dimensions are stated in advertisements
as being 7-1/2" in height, 5-1/2" in depth and 9" in width.
These last dimensions appear to follow through to the end of the Henry Clay's
production in 1899.
All models of the Henry
Clay are considered rare today, and they are seldom encountered.
