A wire muzzle type weaner, attached to a head stall and "chin strap" by adjustable link. The patent was the subject of an infringement lawsuit (Griffith v. Shaw, et. al.) where the finding was this patent did not infringe the limited claims of Shaw's previous patent 419,078. The summary of that lawsuit reveals this patent was assigned to Barbee Wire & Iron Works (Lafayette, IN). In their catalog this appears as the "Hawkeye" weaners.

Note: Early English patents were not originally numbered but they were later assigned consecutive numbers that run from #1 of 1617 to #14359 of September 1852. From Oct 1852 until 1916, patents were numbered by the year and started at patent #1 at the start of each year in January. The patent number used in DATAMP represents the year of issue and the patent number. This patent is #933 issued in the year 1769 This patent covers aspects of Watt's double-acting engine, where steam pressure was alternately applied to either side of the piston. This was also an "expansive" engine, meaning that it used steam under greater-than-atmospheric pressure. The patent specification also described the concept of the steam hammer, which is believed to be the first time that this idea was ever written down.
