how to ID adjustable wrenches?
« on: August 16, 2014, 08:35:27 PM »
I find odd adjustables from time to time. If I google "adjustable wrench", I get hundreds of pics of crescent wrenches, with an occasional  trimo tossed in.

How would you  search  for info on this wrench??

no patent date, no writing at all.

datamp has a catagory index for all the patents. This looks like a 'quick adjust' type, since it has no thumb screw or nut. so look in that index, and turn on the option for 'show pictures' and look at the photos...

Like this: (edit:deleted broken link)
Seems datamp uses some hidden cookies, and so sharing links with pictures on and type search set doesn't work :(


Perhaps this way: http://www.datamp.org/patents/displayIndex.php?source=query&start=0&hp=1


(Or you could just post it here, where someone might point out it looks like a fitzall wrench...)

Rusty, that link brings up only the message "No query specified."

Try this one - a Google search for "sliding wedge adjustable spanner" finds this patent:

datamp has a catagory index for all the patents.  ...  [ snip ]
When I first connected with DATAMP, I supplied the categories for wrenches ...  I started with the categories Dad & Mom used in "Antique & Unusual Wrenches," and factored in everything that had appeared in the MVWC Newsletter.
With several thousand wrench patents in DATAMP, it would be a real challenge to revise the categories & re-assign each of those patents within a "revised" category structure. 
I tried to put all the "FITZALL" types into "wedge adjust" (wrenches:wrench adjustment types:wedge adjust wrenches ).
