What is it? CCVIII

Hi Rob,

Here are some similar tools via patents:

Thanks, I added one of your links to the answer page:

Also thanks to those who helped solve the tire groover, I didn't know what that one was when I posted it.

It was invented by James B. Foot of the Combination Wrench and Jack Company. The patent says he designed it to be ornamental and the user should be able to see how to use it.

This tool was mounted onto a piece of wood along with some information about it, including this drawing:

Below is a later patent by the same inventor, this one has a lubricator as part of the jack. Somewhere on the web I saw a reference to this jack as a wheel holder, this is shown in the patent drawings:

Thanks. So the end of the lower bar has internal threads to cradle the stud at the end of an axle. I think it wouldn't work right except for a certain pitch and diameter, yet he says the wrench is for nuts of various sizes. Apparently a spring is all that holds the jaws against the nut. I wonder how well that worked.

I guess the jack was just to be able to move the wheel far enough for lubrication.

I heard he got a new job, working for Snap-on Tools. ;-)

Cheers! Rich
