UNITED STATES PATENT OFFICE.
HENRY DUREE, OF NEW YORK, N. Y.
IMPROVEMENT IN ROTARY ENGINES.
To all whom it may concern:
Beit known that I, HENRY DUREE, of the city, county, and State of New York, have invented a new and useful or Improved Rotary Engine; and I do hereby declare the same is fully described and represented in the following specification and the accompanying drawings, of Whichclosed byan adjustable cylinder, having steam entrance and exhaust pipes placed at anyconvenient place on the cylinder, which may be used alternately for steam and exhaust or eX- haust and steam, as occasion requires, to reversel the motion of the engine or driving shaft. The cylinder, being adjustable, is not connected with the piston-rod or driving-shaft, and is non-concentric with the piston, as will be hereinafter explained.
In the drawings, A is the frame of the steamengine, which may vary in form as fancy dictates..
B is the adjustable cylinder, sustained, adjusted, and held in place by the screwsc d. Connected with this cylinder are the steam entrance and exhaust pipes, ef, which, as already explained, may be used alternately for the purpose of reversing the engine by re versing the three-way steam-cocks k k, which are similar in construction, an elevation and section of one of these steam cocks being shown in Figs. 6 and 7.
G is the valve-seat attached to the cylinder, and has steam entrance and exhaust extensions, im or m l, a section of same and steam cocks being shown in Fig. 5.
N is the rotary piston, with pistou-rod or shaft N passing through the pistou-arms and open sides ofthe cylinder, and sustained in bearings g/ y. The piston has 'slide-valves 0 O, &c., which may be of any number desired, while I prefer four. These valves act against the inner surface of the cylinder by their own gravity, and for the purpose of aiding them in starting springs P P, 8vo., are attached to their inner ends, as shown in the drawings.
It Will be seen from the above that the piston, being firmly fixed on the `piston-rod, said rod becomes the drivingshaft.
What I claim, and desire to secure by Let ters Patent, is-
The adjustable cylinder B, with its manner of adjustment,in combination with the reversible steam-cocks 7c k and steam and exhaust pipes ef, together with the rotary piston with centrifugal valves, substantially as and for the purpose described.
HENRY` DUREE.
