What Is It?

Filter wrench?

A I WW torture instrument used for really painfull body parts pressing. One end fits the curvature. The other enters at an angle to... uh... don't ever want to know... Yeap. I vote for the filter wrench.

Looks like the lever moves the sliding jaw in & out whilst the angled face jams into something. The hooped shape suggests it fits round a circular shape. Maybe for removing tyres?

Could it be an adjustable pipe wrench?

The filter wrench supposition is of merit.

Truly it is scary there are tools we don't know what were used for.

Tyre bead breaker!

I can see that for a Model T, or A sort of tire, tyre.

What other tools might be associated with this tool, for in the case of bicycle tires you use another tool then to drag the tire off the rim.

Possibly in future puzzles, it would be good if mystery tools were presented with any companions, like bones make a skeleton, and one bone is hard to place without context.

Hi Prof,

You are spot on (Nigh was close) -well done, an old-style tyre bead breaker around the time of the one below.

Are you showing your age or do you have one in the back cupboard like Bricktop.

Bit of both - friend of mine has one and I have helped him (many years ago) change tyres on some of his old cars. Turnbull's Bullturn.

I looked at the pics in a photo editor, and zoomed in to see what the lettering said. On the circular portion in the right photo, it appears to say "TURNBULL'S PATENTY." The lettering on the handle in the left pic is not as clear, but it appears to say, "BULL7URN." I have no idea what either of those mean, but they might be something worth Googling.

It is a tire bead breaker for more narrow tires, like on the antique cars or for motorcycles. Some years back JC Whitney Company sold them, they may still be in thier catalog.

Hi mastrsmth,

You are spot on it is a tyre bead breaker.

Whitney's latest catalogue model is a little different, and for $80.99

I made something similar from a tractor mounted log splitter. Those difficult to break down truck tires were a snap!

Now , how it was used , over the tyre , or passing trough the wheel rays.?

As I see it could not be used on a disc rim .

Over the tire, not through the spokes. Look at the way the pads at the open part are, they are made to go next to the rim and break the bead of the tire from it.

Yes you are rigth, it was my misstake,

Just wake up, neurones are sleeeping yet.

Thanks for clear it

I don't know the technical name, but remember to have seen the use of such components in tying and lifting of loads by pulleys or hoists with ropes / SWR, after tightening ,these locks can be used for binding without slippage.

A bead breaker like this would have been handy to take along on a trip as well as a hand tire pump, a spare tire (without wheel), inner tubes and patches. It was not uncommon to get a flat as tires and roads were not that good in those days.

With a bead breaker like the one shown, the tire and inner tube could be removed and repaired without removing the wheel from the car.

It's an engine valve depressor

Darn, I didn't even get a chance to guess. I was gonna say, it's to make your horses' hooves smaller to fit the horseshoes you have in stock!

It is too small to be a filter wrench as suggested by another member. It is a wrench for fitings under a sink or wash basin like the U trap etc. I have one of these lying somewhere in my garage

I have no idea.But my proctologist has one on his wall.
