This patent is significant for a few reasons. It is the first patent issued to a resident of the American colonies. It is the first (known) patent for an invention created by a woman. She was not permitted to apply for the patent herself, so her husband applied on her behalf, stating that the invention was "found out by Sybilla Masters his wife". Even acknowledging that a woman had invented something was seen as irregular but Thomas was able to do so because of his political prominence (Masters had earlier served as alderman and mayor of Philadelphia, then as a provincial councilor). The Masters produced the cornmeal from this invention, selling it as "Tuscarora Rice" as a treatment for tuberculosis as well as a foodstuff. The invention itself consisted of a horizontal wood with a series of pegs sticking out of the cylinder. A handle rotated the cylinder and pegs to left and then drop mortars into pestles that were filled with corn. The machine could be powered by water-wheel or by horse-power

The key element of the patent is a ratchet connection between the handle and the frame holding the adjustable jaw. This allows for adjusting the angle between the head and handle to enable the wrench to operate in locations difficult of access. A known example uses the simpler of the alternate ratchet forms described in the patent. Tedd Products Co., Rockford, IL marketed this as the HANDI-FLEX wrench. The patents cited as references includes the early Meader ratchet -- nos. 45,931, 525,683, 525,684, 1,564,838, 1,650,085, 1,724,491 and 1,944,171.
