l i Letters Patent No. 64,600, dated llfay 7,1867.
IMPROVEMENT IN ROTARY STEAM ENGINES.
TO ALL WHOMIT MAY CONCERN: ,f
Be it known that I, JOSEPH B. VAN DEUSEN, of the city, county, and State of New York, have invented a certain new and useful Improvement on Rotary Engines, applicable either as motors or pumps, of which the following is a full, clear, and exact description, reference beinghad to the accompanying drawing, forming part of this specification, and in Which- Figures 1 and 2 represent views at right angle to each other of a rotary engine constructed according to my improvement, like letters referring to like parts in both figures.
My invention relates to that class of rotary engines having a revolving cylinder 0r hub, which may be either of equal diameter through its length or of conical configuration in direction thereof, radially sliding piston, and ellipticallyshaped stationary cylinder of equal or tapering diameter, in which the revolving hub and its piston work from or around a centre which is eccentric to the centres of the elliptically-shaped cylinder; and it consists, first, in the construction ofthe side plates, in which the revolving cylinder has its bearings, with recesses of equal diameter with said cylinder, and of sufficient depth to admit so much of the length ofthe cylinder as is not intersected by the sliding piston, and thereby give strength to the cylinder and insure a more perfectjoint between the edges of said piston and the face plates of the stationary cylinder. It also consists in the arrangement of the ingress and egress ports immediately on either side of the permanent abutment of the stationary cylinder, thereby insuring the escape of all the exlmust steam between said abutment and the piston before they come in contact.
Referring to the accompanying drawing, A repi'esents the revolving cylinder or hub, attached to or connected with a shaft, B, workingthrouglr astufiing-box, c. This cylinder, which works in cavities in the sidesD ofthe stationary cylinder, and intersects at its pchiphery the extremity of one of the vertical radii of the latter, is provided with a radially sliding piston, E, tting through slots in said cylinder, and revolving with the cylinder A within an elliptically-shaped stationary cylinder, F, the several centres, e,f, y, of which are eccentric to the centre h of the revolving cylinder, the diameter of which should rule the proportions of the elliptical cylinder. as follows: thus, the radius ofthe revolving cylinder and vertical or minor radius of the outer cylinder or chamber being given, to nd the radius of the major axis of the ellipse, add the square of the minor radius of the latter to the square of the distance between the centres of the revolving cylinder andminor axis, and take the square root of the sum total, which will give the correct radius for the major axis of the elliptical chamber er outer cylinder for the piston E to work throughout a revolution in close contact with said cylinderto which S S are the inlet and outlet pipes or passages. The point at which the periphery of the inner or revolving cylinder comes in contact with the inner periphery of the outer cylinder is called the permanent abutment, and may be fitted with any suitable metallic or other packing, and immediately on either side of this abutment are arranged the ingress and egress pipes for the admission and escape of the steam, so that whichever way the cylinder is rotated, (for it may be reversed by changing the current of the steam from one to the other of these pipes,) every particle of exhaust steam escapes before the 'piston cornes in contact with the permanent abutment, and a smooth, steadymotion is the result.
What I claim as my invention, and desire te secure by Letters Patent, is
l. The revolving cylinder A, constructed so that its ends rotate within recesses in the side plates of the stationary chamber F, substantially as shown and described, for the purposes specified.
2. lhe arrangement of the ingress and egress ports in relation to the permanent abutment and to the revolving cylinder fitted with a single sliding piston for operation substantially as set forth. Y
