View Full Version : Klay's Multiplying Plate Holder - rare back

In my continual quest for early American photographic equipment, I often find things unrecognized. At first I was going to pass on buying this, but then a little research revealed it's an uncommon Klay Multiplying Plate Holder, from about 1893. It's amazing what inventions were made for photographers in the last 150 years.

It's amazing what still shows up after all these years. It looks to be in nice shape, too. Have fun.

I'm not sure I understand, does it allow you to take many, smaller exposures on one large plate?

I'm still trying to figure it out, but will let you know.

This is certainly a very "clean design" version of the multi-backs I have seen. Usually they are exposed columns and rows.

The two dials must adjust the size of the horizontal and vertical framing - whilst the side lever must be "the advance to the next position or release part of the back mechanism to go to the next position"!
Inside there must be a double focal plane shutter type curtain mechanisms making the framing.
How the 8x10 film/plate is installed and how the back box slides over the fixed part of the back must remain a secret until the autopsi has been performed.
