Vise Grip for what?

[CTyankee]

Dug these out of an old tool box my father had. Can anyone tell me what they are for? Jaws don't seem to close anymore than pictured.

They were designed for clamping things like sheet metal, looking at the condition in the photos, it's possible your father used them for clamping things like wood, was your father into wood work ?

Definatly modified by having the jaws (cleanly too) ground off. No clue on the use, likely specfic use.

They look like they have had their toothed jaws removed.

(to slow as always)

I think that tooth at the tip is significant.

Could be for crimping something (like an Oetiker clamp, but with different dimensions), or perhaps for holding spring hose clamps.

Maybe it's hard to tell from the picture..but I don't these were hardly used for anything.

Ahhh.....think you guys are on to something. Never even thought they had been modified. My father worked as a fork lift operator in a printing plant(UARCO). He got a lot of tools from friends in the machine shop. Maybe these were modified for a specific purpose on a press.

looks like they were used in some variety of sand/media blasting

I like the clamp idea, seeing as how the adjusting screw was modified, probably to have more leverage when using the screw with the jaws closed.

Here's the modern Vise Grip 7WR.

Based on your pics it looks like someone milled.ground off the biting surface - see that arc cut in both sides of the jaws?

Either he cleaned them up in a blast cabinet before his last use or these were used specifically when he blasted something.

The sides of the jaws are milled down. That was deffinatly modified by a machinist. Id say your dad may have just ended up with them. They were probably custom fitted for a specific task on a machine of some sort.

I see what you are both saying now. It does look like they went through some type of sand blasting. I know my father didn't do it. He did a little tinkering but never had more than the basics when it came to tools.

You're probably right. He's been gone quite awhile now, so I guess it will remain a mystery.

What does the center brace stamping say Mosstype? I think they were repurposed by a manufacture for original equipment distribution. Based on where you father worked and the products mosstype makes I'd say my hypothesis is valid.

The don't look modified to me. Notice the flat face of the jaws protrudes out to "almost" the leading edge of the single tooth.

EDIT: they must have been though because the patents show full teeth on both drawings.
