"This bit-holder is intended to be used for boring holes near to the walls of a room or in a corner, and in many places where holes cannot be made by the straight bit or auger when used in the common bit-stock. Letters Patents of the United States have been granted for diagonal bit-holders in which a universal joint or beveled gears are used, and our improvement does not relate to these parts of the instrument, but consists mainly in the mode of making the two bearings and connecting them with each other by means of the globular casing which incloses the beveled gears."

The 1858-02-06 issue of Scientific American has an article with engraving on this invention. The article does not indicate whether the inventors were manufacturing this product. However, an example, marked only with the patent date, has been seen, and more recently, we have seen an example marked, "HILL & ADAMS", "CHICOPEE, MASS.", and "PAT. SEPT 29 1857". That patent date actually corresponds to patent 18,282.
