1813 Advertisement: 'SMITH, WITTY and Co.' Patent Rotary Steam Engines. THESE Engines are now brought to a State of Perfection, and are submitted to the Notice of the Public. They will be found to possess peculiar Advantages.— In SIMPLICITY of CONSTRUCTION,— Comparative INCREASE of POWER— ECONOMY in ERECTION, and in OCCUPYING but LITTLE SPACE. The chief Obstacles to the more general Application of Steam as an Agent of Power, have been the Expence of Erection, and the Wear and Tear arising from a Complexity of Apparatus. These Objections are by this Invention in a great Measure obviated. Engines upon this Construction may be extended to any required Power. The Patentees propose to make Engines themselves, and to treat upon liberal Terms with Engineers and Iron Founders, whose particular Attention they wish to draw to the Consideration of the Improved Principle of this Engine, and to whom they will give every requisite Information. An Engine of Thirteen Inches Cylinder, is now erected, and may be seen at Work, at Mr. Henry Blundell's, Colour Manufactory, Hodgson-Street, Groves, Hull, where Reference is made to prove the Superior Power and other Advantage, above stated. Application addressed to Smith, Witty and Co. or Personally, to Richard Witty, Exchange Alley, Hull. Hull, 12th. August, 1813.'
