Anyone know what Huber machine this wrench was used on ? I do like a well marked wrench. I started to say some dim bulb ground a notch in the left hand end but maybe he needed clearance and this made it fit. Rathbone lists this as Huber wrench but has no picture.

Jim,
It's listed in a in a Parts book for New Huber Engines (1875-1924) as a "Piston and Slide Valve Stuffing Box Wrench". Nice wrench and one I don't have.

The description of Slide Valve Stuffing Box Wrench indicates it was used on a steamer.   The reason it says Piston as well, is because on a steam engine, the piston isn't much more than a plate that is bolted to the cross-head shaft, which is then connected to the connecting rod.  Just in case anybody wondered.

I used to like irritating the steam engine collectors by asking them what, precicesly , is the difference between stuffing and packing ; P

Think about how little torque you can apply with that short wrench to a *very important* nut LOL

I wonder if the notch was from accidently leaving it on the nut and starting the engine...hmm

Rusty, stuffing is what is put in the bird at thanksgiving, and packing is what the spouse does after she catches a whiff of perfume on your shirt!  Or so I've been told.##########

I love that style wrench.  Large openings and short wrench.  Nice find Jimwrench.
