my brother gave me this today as a birthday present, I'd never seen one before.. that I remember anyway. anybody else got a quirky old tool for show and tell?
Henry made all sorts of unique tools. There must have been a reason for this crooked crescent wrench.
I had one like that until someone liked it better. It actually came in handy a few times. Mine was painted black from new.
Adjustable with quick clamp and release feature...the jaws are also grooved for spring clamps or something similar... I found it on google patent...it had a Canadian origin...1919...
This was given to me from a good friend he got it at a garage sale...it came from an WW11 era aircraft plant I worked in...the jaws move straight up and down...clamp leverage is perhaps more robust than typical pliers...it also has a cutting feature...though not an adjustable it is a pretty odd duck...US in origin... AVRO was around from about 1940 something till 1959 or 60ish in Malton, Ontario, Canada... Lancasters, Ansons, Jetliner, CF100, CF105 Arrow, Avrocar were just some of what went on there in the Hamb era... https://en.wikipedia.org/wiki/Avro_Canada Was it used on aircraft or maintenance...not sure but the straight close and grip jaws would work well on flat aluminum and related materials... http://alloy-artifacts.org/wm-schollhorn-company.html ...why the internet is cool... The pair I have is newer but this company has roots...again it may have found a repurpose to aviation...
One end is for hammering on stuck starter solenoids, the other for hammering on bolts to start them (cross threaded). Cheers, Harv
Crescent 8-10 Inch Double Adjustable Wrench We'll begin with an early double-ended wrench, a once common tool that's now regarded as a novelty. Fig. 10. Crescent 8-10 Inch Double Adjustable Wrench, with Insets for Side View and Back Side Detail. Fig. 10 shows an early Crescent 8-10 inch double-ended adjustable wrench, marked "Crescent Tool Co." and "Jamestown, N.Y." in forged raised letters, with "Crescent" and "Drop Forged Steel" on the back side. The overall length is 10.1 inches, and the maximum jaw openings were measured at 1.0 and 1.1 inches for the 8 and 10 inch ends, respectively. The finish is polished steel. The head thickness was measured at 0.58 and 0.73 inches for the 8 and 10 inch ends, respectively. This wrench has an additional "Patented" marking forged into the shank, and this is believed to be a reference to patent #1,133,236, issued to K. Peterson in 1915. The patent describes the use of a tension spring to help hold the adjusting screw in position. http://alloy-artifacts.org/crescent-tool.html
Yeah, those adjustables are called shifting spanners here. Well, shifters. I guess because the jaw position shifts. Shifter is all I've ever known them as. In the U.S. Cresent became the generic name. Like how English people 'hoover' the floor with any brand vacuum cleaner.
Kinda like vise grips...one size fits all...metric or sae...but both are not true...I first thought Paul's wrench was crazy but the heads have different ranges...less trips to the tool box...and the fact they're close means if one doesn't fit the other will...clever stuff going on...Dad creating the tool design and the young hoodlums using the tools to wrench them Hotrod/Customs...
This one is marked Fordson which was , of course, a tractor. Ive never seen one with an adjustable head, but I have seen some half round ones with a regular box end that were said to be for alternators and generators. Thanks for the pic.
I had one of these parallel pliers in my aircraft maintenance toolbox when I did my apprenticeship about 45 years ago, used them for about 25 years, and then they broke. Not overloaded or mistreated, the jaw just cracked off. Never seen one since. The shifter is also called the AFS spanner here, Any Flippin' Size. I have a strange shifter which has the moveable thread cut opposite to all the others, it opens when you turn the screw in the "closing" direction of the others.
That makes complete sense. No handy tool box. No workbench to put things. A desire to use one hand for steady, while one hand pulls on the wrench. And 12 stories up and away from Mother Earth

These are a vintage pair of (Klein) lineman's pliers, they were my grandfathers, they still are very accurate. Built to last a lifetime ! My grandfather used old green garden hose, to cover the handles.
Miners wrench still available new Since everyone uses it for a hammer the hammer head is built in. The round end is broached as a 7/8 box end wrench. I believe this was built for underground miners working on the tracks.
