Monday Mystery, twisted thing. (Updated)

Looks like something a blacksmith might have made but for what purpose, I'm not sure. Guesses?

Dave says, "Its a caulking iron for lead plumbing joints, packing oakum fibres in the joint.  1973 Mephisto catalog here.

  1. in the late 1960's, working on turbine propulsion controls, we used to bend & twist Allen wrenches into strange shapes in order get them square on a buried screw or adjustment & still be able to apply proper torque. Maybe something of the same idea here?

  2. It is a caulking iron for lead joints in cast iron pipe. The one pictured is for caulking oakum fibers in the joint where the pipe is against a wall or other object where you don’t have easy access. After the oakum is driven into the joint (caulking), the joint is filled with molten lead then additional tools are used to pack the lead deeper into the joint sealing it. I never did it but used to sell all the tools to do it. The one pictured is a left hand one and there’s a corresponding right hand version.

  3. That was me above. The main brand we sold was Hood Brothers out of Philadelphia. Here’s a link to a Mephisto catalog showing all the different types

  4. It looked like that type of tool, but for a use I’m not familiar with. It looked like someone had been using a hammer but the business end was not sharp. Thanks for the link.
