Document Description:

This advertisement titled “Cotton Ginning” is the first public notice of Miller & Whitney’s cotton gin.  Miller &Whitney expected to make a lot of money from their endeavor, and they decided to charge a toll to use their machine.  The ad states that Miller will gin cotton for planters, in exchange for one pound clean cotton for every five pounds brought to the gin.  Many planters resented paying a 20% toll to gin cotton, and it became apparent that anyone with blacksmith’s tools could construct their own copy of the gin. 

The next advertisement titled “A Caution” reminded planters that Whitney held the patent for this gin.  Miller & Whitney made it clear that they would use the laws protecting patents against those who made gins without permission, unless they immediately turned in the illegal machines.  More and more planters claimed to improve upon Whitney’s design for the gin, the most common improvement was to use saw blades instead of wire teeth.  Miller and Whitney asserted that using metal to tear seeds from the lint was their idea, adding that a saw blade was only “a more expeditious mode of attaching the tooth to the cylinder.”  In a letter to Whitney, Miller wrote, “it seems to be a general opinion among our best friends that the machines which are made by the Country blacksmiths clean the cotton at least as well, and clean it in much larger quantity than ours.”   Miller & Whitney faced their biggest legal challenge in 1796 when Hogden Holmes received a patent for his saw gin.  A long and bitter lawsuit followed which ultimately ruled in Whitney’s favor.  The experience, however, was a nightmare for Miller & Whitney.  Whitney’s patent was not renewed in 1808, and both men actually lost money on the venture.

Cotton Ginning.

The subscriber will engage to gin, in a manner equal to picking by hand, any quantity of the green seed cotton, on the following terms; viz. for every five pounds delivered him in the seed he will return one pound of clean cotton fitted for market.
For the encouragement of cotton planters he will also mention, that ginning machines to clean the green seed cotton on the above terms will actually be erected in different parts of the country before the harvest of the ensuing crop.

A Caution.

The subscribers having, by the industry and attention of Eli Whitney, and at a heavy expense on the part of Phineas Miller, invented, perfected, and brought into use, a new constructed machine for ginning cotton, had flattered themselves that the Planters would have been satisfied with the moderate terms proposed for cleaning out their crops, and that a property, acquired in a manner so advantageous to the general interest of the public, would have been protected from injury, without the intervention of the laws. But since this is not likely to be the case, the best information having been received that several attempts have been made, under the pretext of improvements on their machine, to trespass on their rights, and to wrest from them their hard earned privileges, they are induced to give the following public notice: That the said Eli Whitney did, on the 14th day of March, 1794, obtain a patent, executed in due form, under the great seal of the United States, granting to him the full and exclusive right and liberty of making, using, and vending the others to be used, his new and useful improvement in the mode of ginning cotton, for the term of 14 years, beginning from the 6th day of November, 1793, as will appear on record in the office of the Secretary of State to the United States: That, on the 21st day of June, 1794; the said Eli Whitney, by deed of transfer on record at said office, made conveyance of one half of his interest in said patent to the said Phineas Miller. That the principle of the Improvement on which said patent is founded consists in picking the cotton from the seed with teeth, from which it is afterwards removed with a brush. This improvement being perfectly different from any method heretofore practiced for ginning cotton is the more clearly and explicitly secured by the laws of the United States made for the encouragement of the arts. And since the property acquired by the patentees in this invention is placed under the same protection as any real estate belonging to their fellow citizens, they will view in the same light every trespass or injury to which it may be exposed, and will certainly make use of the means which the laws of their country have placed in their hands to obtain ample redress. As they will be forced, however, with great reluctance, to this necessity, they now offer to those who have hitherto been ignorant of their patent, and who have constructed the machines upon principles, the use of which is thereby exclusively secured to the patentees, that if they will immediately desist from all further trespasses, and deliver up the machines so constructed, they shall not be prosecuted for the heavy penalty they have forfeited by the laws, but meet with every reasonable indulgence from Miller and Whitney. Savannah, May 1, 1795.
