SOLVED! 1850-1875 PhotoAlbum Spiral cam Booklatch

[steelheadwill]

Hello All!
Dug this a day or two back.
Turn the round spiral cam, and the two bell shaped pieces extend and retract,
(or vice versa). wondering if anyone knows what this item was used for?
Nola_Ken suggested Book Clasp.
Any more ideas would be welcome!
thanks for looking

Bump! really interested to see what this turns out to be.

The piece on top in photo 2 would accept a slide pin connector, like a hinge.
hole in bottom would accept screw/bolt/pin.
I'm baffled by this, some type of light duty precision adjuster?
The bell shaped pieces move very little in comparison to rotation of the disc.

Re: Spiral cam mechanism

looks to be a book latch. turning the cam would allow a tightening of the latch, what ever it came off of.

Re: Spiral cam mechanism

Sounds like a green check to me.
booklatch wouldn't have to move much.
hinge pin attached on back cover, hole went over pin on front cover,
twist the disc, it was locked

Nola_Ken gave the first booklatch id in 'Todays finds'
Seconded by Lostcauses here.
Now I see clearly
Thanks guys! Great work

Don't want to seem stupid, but what is a book latch and how does it work?

Some old books had a clasp on them that would keep them shut,

Steelheadwill.....you're not going to believe the pic I just found online....

Creskol, here's a site with some history of book clasps. I always thought they were really neat, and something you just don't see much anymore.

GreatID Nola Ken. I remember personal diarys used to have clasps. My sister had one in the late 60's. You had to push the tiny slide button to open it. Some also had tiny keys.

Thanks Ken .. I am familiar with the old strap-type clasps, but I have never seen one of these before. Thanks for the education. Learn something new every day if you aren't careful.

Re: SOLVED! Spiral cam Booklatch

now the trick is to date it.....

One would think that such a neat design might be patented
The item shows no numbers or letters.
Can a patent search be done by item description?
If I were to guess from the condition of the book shown, 1880-1900

Yes but its a lot of searching.

You could go to "advanced patent search" or "restrict by issue date" and type in an estimated date range. I clicked on "filing date oldest".
Or use different key words.

Awesome picture!

looks like it is a clasp for a photograph album.

Re: SOLVED! Spiral cam Booklatch

The guy with the book clasp site says it's likely to be from a Victorian photo album, and guessed maybe 1850 -1875.
