Works Like an Extra Pair of Hands!

How the Scroogeclamp works

The drawbar is left-hand threaded on one half and right-hand threaded on the other, with a handle through the middle. Each end threads into a bracket with attachment holes. Turn the handle one way and the brackets move apart. Turn it the other way and they move together.

The tool produces 2,000 pounds of push or pull with an 80 pound force on the handle. The handle bends at 2,600 pounds, a built-in safety factor that keeps it from being overloaded by, say, someone putting a piece of pipe over the handle.

If you used ten of them, you could produce 20,000 pounds of push or pull, distributed as you wished.

An entirely new tool

The Scroogeclamp is an entirely new tool, rather than an improvement on something already available. It has hundreds of uses. The most obvious is to plumb stud walls and posts. Run it diagonally on a stud wall and it will square up the wall. Fasten it between two studs and it will push them apart or pull them together.

How long it takes

At the 1998 Ohio State Fair, someone asked us how long it took to use. They timed it. Twelve seconds!

One Scroogeclamp™, a 2×4 or 2×2, and a short piece of wood make a complete adjustable brace.

Other uses

Whenever a new house is built, between the time the foundation is dug and the new owner moves in, there are multiple uses (needs, actually) for this tool.

  • Adjusting concrete forms

    Concrete contractors can use them to adjust concrete forms to exactly where they want them.

  • Straightening warped lumber

    If it starts raining before the sides and roof are on and the framing lumber gets wet, warps, and twists, the tool can push and pull it back into shape.

  • Pulling a racked building back into shape

    If you have an old shed that is racked out of shape, put ten or twenty tools throughout it and tighten them every night. With the expansion and contraction from temperature changes and vibration from wind, over a few months you could move the building back into shape. Much cheaper than building a new building!

Someday, I expect every professional builder or carpenter will own at least one (or two, or four) pair(s), and eventually it will be in the workshop of every home handyman and do-it-yourselfer in America! With all the buildings, stationary and moving equipment, fences, and gates on the modern farm, every farmer will need at least one pair. This tool works like an extra pair of hands, and everyone needs an extra pair of hands!
