DIYbanter - What would this JACK be called?

wrote in message

The best way I can explain what they used, would be one of those small
floor jacks, but rather than wheels on the bottom, there was a lower
wedge, and rather than the round pad on the top like on the floor jack,
was a top wedge. The handle was placed into a hole on the rear (just
like on the floor jacks), and as it was pumped, those wedges separated
and lifted the object.

Did it look like this:
