UNITED STATES PATENT OFFICE.

OLIVER WRIGHT AND A. A. WILDER, OF WARSAW, NEW YORK. ROTARY 
STEAM-ENGINE.

Specification of Letters Patent No. 667, dated April 2, 1838.

To all whom it may concern:

Be it known that we, Oliver Wright and Aretus A. Wilder, of 
Warsaw, in the county of Genesee and State of New York, have 
invented a new and useful Improvement in the Reacting 
Steam-Engine; and we do declare that the following is a full and 
exact description.

The nature of our invention consists in providing the apertures 
or orifices of the engine with springs and set screws so that 
they may be opened or closed as may be required. This is effected 
by having a spring placed in the apertures and riveted to the 
part forming the end of the tube or steam conductor, the set 
screw passes through the same so that by starting the screw 
forward it presses against the spring and closes the orifices.

Figure 1 represents the engine wheel with one of the side plates 
removed to show the manner of constructing the same. a, a, the 
hollow arms or tubes which convey the steam from the center to 
the edge of the wheel. b is two iron plates about six inches in 
diameter placed each side of the arms or tubes and firmly riveted 
together for the purpose of holding the foot of the false arms. 
C, C, C, false arms through which the side plates are riveted, d, 
the rim through which the side plates are also riveted. e e 
represents the springs in the hollow arms. f, f, set screws for 
moving the springs e, e. Fig. 2 represents one half of the case 
with an opening or door on the side for the purpose of 
conveniently having access to the orifices. Fig. 3 a small door 
to fit the opening in the case.

What we claim as our invention and desire to secure by Letters 
Patent, is�

The application of springs and set screws to the apertures of 
rotary steam engines, and also of placing a door in the case so 
that the apertures may be closed or opened without taking the 
case apart.
