GB Patent: 171,500,401

Cleaning and curing the Indian corn growing in the several colonies of America Patentees: Sybilla Masters - Philadelphia PA , Thomas Masters - Philadelphia PA Granted:1715-11-25

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

Slidable Jaw, Ratchet-Operated Wrench Having A Detachably Pivotally Adjustable Handle Patentee: Ted Stang - Rockford IL Granted:1955-03-22

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.

GB Patent: 184,209,382

Improvements in machinery or apparatus for forging, stamping, and cutting iron and other substances Patentee: James Nasmyth - Patricoft, near Manchester England Granted:1842-12-09

The piston rod coming out at the bottom of the cylinder is attached to the hammer. High-pressure steam is let in under the piston, which raises piston and hammer to any required height. The hammer is guided by planed rails. The cylinder valve opens the hammer falls on the work with full force due of gravity and then is immediately lifted by new steam entering the cylinder. To lessen the force of the blow the steam timing can be advanced so that the steam enters the cylinder before the hammer has hit the work, and that steam absorbs some of the force. Nasmyth claimed that this system could be so precisely adjusted that the hammer blow could be made to step within one-tenth of an inch of the anvil. A later refinement was to use a double-acting cylinder that allowed the force of the hammer to exceed that due solely to falling by gravity.
