"This invention relates to a new and improved boring-tool for boring holes in wood for the purpose of facilitating the sawing of ornamental open-work, where holes are required to be bored to admit of the insertion of the saw, and where curves form a part of the configuration of the work.

"The invention is also applicable to the boring of holes for any purpose, and it has for its object the ready adjustment of the cutter for the cutting of holes of various sizes and the obtaining of a great range of adjustment, so that quite small and quite large holes may be bored with one and the same tool."
