Anyone with a guess as to its use?
Update; solved! Reader JP found this; "Newleva Patent Spanner".
From the Spanner and Wrench Collector page.

They come up on tool collector auction sites as "Newleva Patent Spanner".
ReplyDeleteAt some point they must have solved some accessibility problem, I guess.
How long is that thing? Pretty interesting design eh!
ReplyDeleteAll I have is the picture. Everything but the adjustable wrench head looks like an Anglepoise light. The idea seems to be to keep the wrench head in the same attitude. I can't see how it could be useful for any actual wrench-type work!
ReplyDeleteHowever JP's comment brings this entry up. https://www.htpaa.org.au/images/SWC/Spanner_and_Wrench_Collector_Issue-15.pdf
ReplyDeleteI guess the head could be rotated a few degrees by manipulating the 'lever" at the end of the "bars/rods".
"The Newleva (which I assume is a twist of New Lever) exhibited by M. Russel and Co.,is one of a series of unique patented tools for getting at nuts and pipes difficult of access by ordinary means, the hand lever on the end spanner only being worked, causing the head to partially rotate."

ReplyDeleteAnother wacky whatever tool like the thousands they come up with today maybe?
Good job! Thank you.
ReplyDeleteI can't really imagine it being useful in very many cases. I don't think the short lever would be able to generate the torque required on a 3/8" or 1/2" or similar bolt.
