Identification help-card catalog?

Hi Everyone....
Thanks in advance for anything you can help me on. I recently purchased what I thought was a card catalog. (I am a librarian). It is not like anything I have ever seen. It is about 3 feet tall. It also has a roll down feature. Each drawer has maker's sticker. Anything you could help me on would be great!

Sincerely,
Phyllis Lankford

 

That is SO cool ! No lock anywhere? Id think more for maybe patient info or the like,otherwise why the roll down cover? Id have jumped on this with both feet!

 

No lock. I got this for 250.00 so I thought that was a deal. It needs a little restoration as it was taped shut.
Library catalogs usually have a rod in the middle of each drawer to hold the punched cards in place. This one does not have that.

 

Here is what I imagine is one of the patents.

This site has some catalog photos from this company showing some models with the roll top.

Such as this one.

 

BTW I love it too!

 

A good buy at $250.00. These are one of the few examples of antique furniture that have kept reasonably good value. People are enamored with lots of little drawers.
