Lilienthal museum gave it the German name as "Schlagflügelapparat" meaning "Flapping wing apparatus". They list the name as Joseph W. Kaufmann, which doesn't match the middle name Meyers above but the patent seems sure to be the same. (Abridgments has J.M. Kauffman.)

The Lilienthal museum's page roughly translated says:

This steam-engine-powered aircraft flight was patented in Paris. A model was shown at the 1868 Aeronautical Exposition in the Crystal Palace. The machine has several pairs of wings, of which the front birdlike in elongated shape works as a flapping wing. Behind that is a wing package of four parallel layers clamped by an iron frame. It should probably be made ??of sheet metal. Were called air or land carriers, determined to carry the apparatus and to prevent rapid rise and fall. In the model, they broke through their weight and resistance together with each Ver-examined. Rear wings were attached, which should serve as a stabilizer. The wings will make 150 to 200 beats per minute, the speed will be 12 miles per hour. It was on a chassis with four wheels ge thought-where should the ground Anlaufgeschwindig speed can be achieved. For air travel to New York in 6 hours and the hull was designed as a ship, that is an amphibian. See Leipzig Illustrated Newspaper, 5 September 1868, Source: Source 1, page 71, Search: Seifert

[Provisional protection only.] Aerial machines without aërostats; starting.- Relates to apparatus for propelling passengers or goods, from one place to another, through the atmosphere and on land and water. The apparatus comprises a boat or car in which are a steam engine and a boiler heated by the combustion of oils. The boiler is either vertical or horizontal, and has a double shell to allow of the free circulation of the water. For regulating the pressure of the steam within the boiler, an apparatus is em- ployed consisting of a cylinder communicating with the steam space and containing two pistons con- nected by a rod which is extended downwards and is furnished with a smaller piston sliding in the short end of the tube of a mercury gauge. In the event of an excess of pressure, the pistons are depressed until one or more ports are opened through which steam may escape; the escaping steam may sound a whistle. This apparatus may be applied to steam boilers generally. For regulating the flow of oil as fuel, a cylinder contains a piston acted on by the steam and controlling the valve through which the oil is supplied. The engine cylinders are placed near the middle of the boat, or one on each side, and the piston-rod cross- head is linked to two oscillating arms or levers extending across the boat. The outer ends of the arms are continued in the form of a light frame- work of steel tubing or T steel &c., covered with silk &c. To the propelling-boat is attached a second one, which acts as a tender and carries fuel and stores, and behind this are cars for passengers or goods. These cars are provided with wings fixed at an adjustable angle to their sides, to assist in supporting the apparatus when in motion. All the cars may have tails and guides or sails for steering. They may be fitted underneath with buffers containing pistons, which may be forced out by steam pressure for lifting the apparatus at starting. Wheels may also be employed, actuated by the engine, on which the apparatus may be started on land, and which serve as flywheels when in the air. The apparatus is balanced by a weight at the end of a movable pole or telescopic tubes below it. The cars are capable of floating on water; they can also be made separate, or all fixed together. The wheels are made with grooves &c. to receive floats when the apparatus alights in water, the wheels then acting as paddles.
