Something to do with the wheels or a jack?
I kept googling and it's a rim splitter. No idea how to use it but I have one ;)
This thread should explain how to use it. The pictures are really helpful!
I see the crank has been broken and brazed. be careful putting very much crank pressure on it, that handle could break suddenly at the repair and hurt you. These things are cheap, buy another one to actually use. Gary
Here' instructions I found online, hope you can read it.
That braze repair looks good to me as being cast iron it broke when someone threw it on the floor!! Bud,in Wheeler,Mi.
A very nice tool to have.
I have a similar tool, except the threads are reversed and the arms work on compression.
The box and paperwork say it is a fragrant mound condensor.
Thanks everyone. I'm not sure if I will be changing the rubber, looks kinda unsafe :-)
Big thanks to Howard for the picture and Andrew for the link.
There was one under the front seat when I bought my T too. It had a lot of writing on the body and arms. "PACIFIC BALLOON RIMTOOL, MADE IN ENGLAND, JUNIOR MODEL FOR LIGHT RIMS, NOT FOR GARAGE USE, PAT IN ENG CANADA & USA OTHERS PENDING."
That is a very helpful tool for the 25-27 split rims. You hook the tool and retract the rim so that the tire can be removed and another tire can be placed. Then you reverse the tool and crank the opposite way to expand the rim to fit the tire. It was only used on the Model T for the 4.50x21 tires. The wire spoke wheels used the same size tires but had a drop center rim so you didn't need the tool.
Almost impossible to line up the rim ends and expand them enough to lock it in place. This tool makes it easy. A must have for split rims. Jim Patrick
