PATENTS are granted in the United States, giving the exclusive right to the inventor, his heirs and assigns, to make, use and sell the invention or discovery throughout the United States and the Territories thereof for a term of seventeen years.

Before any inventor or discoverer can receive a patent he must make a written application for it, addressed to the commissioner of patents, and file in the patent-office a written description of his invention or discovery, giving details of its various parts, the materials used, how constructed or compounded, the manner of operating it, and the results proposed to be accomplished by its use; all expressed in such full, clear, concise and exact language that any person, familiar with the art or science which the invention is designed to benefit or illustrate, may be enabled to make, construct, compound and use it. If it is a machine, the principle on which it performs its work must be explained, as well as the best methods of applying it to the objects of the invention. This is required to distinguish it from other machines. Every part, improvement or combination of the invention which the applicant claims as original with himself, must be particularly pointed out.

The specifications must be signed by the inventor and be attested by two witnesses.

When the character of the application requires drawings of machinery, or parts thereof, the applicant must furnish one copy of each drawing, signed by the inventor or his attorney in fact, with two witnesses. This copy is filed in the patent-office, and the government officials attach another copy to the patent as a part of the specifications.

If the article to be patented is compounded of several ingredients, specimens of the materials used in making it, and of the whole composition, must be forwarded with the application, in such quantities that experiments can be made according to the specifications by the official examiners.

Where a machine for which a patent is asked can be illustrated by a working model thereof, the commissioner may require the applicant to furnish such model, in order to show how all parts of the invention are to be operated. The model must not exceed one square foot in size.

An applicant for a patent-right must swear (or affirm) that he is, or believes himself to be the first, or original, inventor or discoverer of the art, machine, manufacture, composition or improvement which he desires to patent; that he does not know, and does not believe, that the same was ever before known or used; and must tell of what country he is a citizen. This affidavit may be made before any person authorized to administer oaths in the United States; or, if the applicant is a resident of a foreign government, he may take this oath before an American minister, consul or a notary public of the foreign country where he resides.

Application For A Patent

To the Commissioner of Patents, Washington, D. C.: The petition of Joel Rice, of Florence, in the county of Erie, and State of Ohio, respectfully represents:

That your petitioner has invented a new and improved mode of creating steam-power for the operation of machinery, propulsion of vehicles on common roads, and of all kinds of crafts upon navigable waters, which he verily believes has not been known or used prior to the invention thereof by your petitioner. He therefore prays that letters-patent of the United States may be granted to him therefor, vesting in him and his legal representatives the exclusive right to the same, upon the terms and conditions expressed in the acts of Congress in that case made and provided; he having paid Fifteen

Dollars into the treasury, and complied with the other provisions of the said acts.


Form Of Specifications For A New Method Of Creating Steam Power

Be it Known, that I, Joel Rice, of Florence, in the county of Erie, and State of Ohio, have invented a new and useful machine for the purpose of creating steam-power for the operating of machinery, the propulsion of vehicles on common roads, and of all kinds of crafts upon navigable waters; and I do hereby declare that the following is a full, clear and exact description of the construction and operation of the same; reference being had to the annexed drawings, making a part of this specification, in which figure one is a general view, in perspective, of the complete machine attached to an ordinary steam-engine; figure two is an ordinary fire-arch, surmounted by a semi-globular iron kettle, with a flat, iron top, closely fitted to the entire upper rim of the kettle, and fastened tightly down thereto by four separate hasps attached to said cover, staples and keys, all of iron, as shown in the working model accompanying this application; figure three is an iron pipe (a) three-fourths of an inch in diameter, the upper end of which passes diagonally into the lower part of the right side of the kettle, and the other end is attached to a tank of water (b) placed upon a standard (c) above the top of the kettle and one side thereof, so that by a hydraulic pressure, regulated by an automatic valve (d) within said pipe, and a small syphon (e) extending from the tank to said pipe outside of said kettle, a supply of water equal to half a gill is ejected into the kettle through the pipe every thirty seconds; figure four is a pipe (f) of similar size and construction, passing directly from the inside of the kettle, outwardly, to the steam-chest of the engine, for the purpose of conveying steam from the kettle to the engine as a motive power for the propulsion of said engine. What I claim as my invention and discovery, and desire to secure by letters-patent, is the production of superheated steam by the injection of half a gill of cold water, every thirty seconds, into the red-hot kettle, and the passage of the superheated steam directly to the engine to supply it with power, to perform any work that any steam-engine may perform, increasing the ordinary force of common steam from two to fifteen-horse power by my invention, and the use of superheated steam created by the process above described. I also claim the right to patent, as my discovery and method of application, the use of superheated steam as a motor in the propulsion of all machinery to which it can be applied by ordinary steam-engines.
