The petition of SAMUEL COLT, of Hartford, in the State of Connecticut, respectfully represents that he is the sole patentee and owner of Letters Patent granted to him on the 29th day of August, 1839, for an improvement in fire-arms and in the apparatus used therewith; that he has reason to believe that through inadvertence and mistake the claim made in the specification of said Letters Patent is too broad, including that of which the said patentee was not the first inventor, although he avers that he was an original inventor thereof, and had no knowledge when he applied for Letters Patent therefor that any other person had ever used the said improvement before that time. Your petitioner therefore hereby enters his disclaimer to that part of the claim in the before-mentioned specification which is in the following words, viz: “I claim making the aperture through the tubes or nipples (which receive the percussion-caps) conical or funnel shaped, for the purpose of freely admitting the fire from the percussion-cap and concentrating it as it enters the chamber,” which disclaimer is to operate to the extent of the interest in said Letters Patent vested in your petitioner, the same being the whole right, title, and interest thereby granted to him, as aforesaid, he having paid ten dollars into the Treasury of the United States agreeably to the provisions of the act of Congress in that case made and provided. Dated at Hartford this 5th day of August, A. D. 1853. SAM. COLT. In presence of-- L. P. SARGEANT. * * * * * Transcriber’s Notes: Page 1, “delare” changed to “declare” (I do hereby declare) Page 1, “guus” changed to “guns” (guns, and pistols) Page 3, “repreresenting” changed to “representing” (the circles _r r_ representing) End of the Project Gutenberg EBook of United States Patent Office Application--Improvement in, by Samuel Colt
