The Stovebolt Site Forums The Shop Area The Tool Chest Jack?

Any ideas what this thing might be? I'm guessing a jack of some sort?

That would be my guess too. What happens when you pump the handle? I'm guessing that the center post just raises a bit. The upper part gets positioned as far up as possible, then pushing the handle levers the center post up just a bit. Maybe some sort of aligning jack, as it doesn't look like it can move very far.
I've never seen anything like it.

Looks homemade to me and built for a special purpose.

I doubt it's homemade. The DIY guy would probably use bolts instead of rivets to hold it together.

At the moment it is stuck, so I don't know what it does. It might even be missing some springs?

Interesting how the base has holes in it indicating that it may have been fixed to a single location. Perhaps a type of press?

A load leveler of some type?

Have you looked for any kind of markings on it? Sure would be interesting to find a manufacturer's name or part number to research it some more.

There are no markings on it that are obvious.

I did spray it with some break free and got it "working". The handle raises the frame up a few inches. The widget that is sticking out on the top is adjustable to the notches.

if someone wants one of those strange flat no marking jacks there is one for sale in northern cali

Post the link here, I'd like to see what it is used for.. curiosity you know.

not a lot of info in that link

The only way that would be useful would be to adjust the upper hook under something, push the handle down, to raise the item, stick a block under it, raise the handle, readjust the hook, push the handle down, insert a block, etc, etc, etc. Wouldn't work for a vehicle, because the suspension probably would relax before the tire got off the ground to block it up. I guess you could block it under the frame or bumper.

I got an answer from the craigslist ad. He has no clue either, but it did belong to his grandfather.

I'll move this to the tool shed and see if anyone over there knows. thanks for the input, so far.

My vote is it's a Buckboard/Wagon Jack.

How tall is it?

Looks like the lifting paw ratchets up and down the cogged teeth on the shaft, right?

It's about 26-27" tall. The pawl? slides up and down, it sits on the teeth. The handle lifts it about 4 inches or so.

Definitely a specialty jack for a specific application. Doesn’t appear very heavy duty.

Any chance you could pm the link to me? I am in northern CA and that would look cool in my garage

figured it out
it's just one of many early carriage jacks, used for holding them up for wheel service, that's why it starts so high off the ground and it not very strong, do not lift heavy loads and never trust it with more than your friends foot.
once you know what to look for they are not difficult to find

hi Twin Jimmys,
the link i posted earlier is gone now, i can't find the post on craigslist either, but i found another one in 1 minute knowing what to look for, i'll PM you that one, it's a bit more pricey but it's in better shape.

Depending on the type of carriage ( lightweight ), probably a single horse. There were jack ports on the sides. Somewhat like VW and Porsche used for there heavy side lifting. This jack would only lift about as much as one man but, would free up a person to adjust axle bolt. Most were Blacksmith made. Doc.
