Description:

"My invention relates to tools for boring holes in metal plates, and particularly for boring boiler-plates to receive the tubes." This seems like a strange invention to be assigned to the company that made the Linotype machine. They did also make a small line of adjustable reamers and taps that had been developed in the course of developing the Linotype machine and working out its manufacturing process.
