Description
MATTHEW SMITH, OF PITTSBURG, PENNSYLVANIA.
ROTARY STEAM-ENGINE.
Speccation of Letters Patent No. 23,956, dated May 10, 1859.
To all whom it may concern:
Be it known that I, MATTI-inw SMITH, of the city of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Rotary Steam-Engines; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon, similar letters referring to similar parts.
The nature of my invention consists in an arrangement and combination of a revolving cylinder, steam chest, cam yoke and supply and exhaust passages, with a stationary cam and supply and exhaust chambers, the whole being arranged and operated in the manner and for the purpose hereinafter described.
To enable others skilled in the art to make and use my invention I will proceed to describe its construction and operation.
In the accompanying drawings, Figure l, is a top view of the rotary engine. Fig. Q, is a cut or sectional view. Fig. 3, is a side view of the cylinder, steam chest, stationary cam and revolving yoke. Fig. il, is an end view of the cylinder steam chest and revolving yoke. Fig. 5, is a cut or sectional view of the shaft showing the steam passages.
(a.) represents the bed plate or frame work on which the engine stands, (b) is the cylinder, (c) is the steam chest, (CZ) is the ily wheel, (e) is the fly wheel shaft, (f) is the hollow shaft on which the cylinder, steam chest and cam yoke revolve, (g) are the pillow blocks or bearings for the shafts (e and f), (it) is the stuffing box of the cylinder, (i) is the stuffing box of the steam chest, (j) is the piston rod, (n) is the slide valve, (m) is a bent rod which connects the valve stem with the revolving yoke (7c).
`The cylinder, steam chest, and slide valve are all constructed and arranged as in the ordinary stationary slide valve engine.
(K) is the cam yoke which is attached to the cylinder and revolves with it. The revolution of this yoke around the stationary (if) are rings furnished with glands (s). Y
These are used to hold the packing between the steam chambers and the shaft.Y
The steam chambers extend all around the shaft so that the flow of steam into the supply passage (u) and out of the exhaust passage (e) .is never interrupted while the shaft is revolving.
- (t) are pedestals which support the steam chambers (y) and p). 'It will be observed that the shaft on which the cylinder revolves is placed out of the line of the ily wheel shaft a distance equal to one half of the length of the stroke of the piston. 1
The operation of my engine is the same as the ordinary slide valve engine with the exception of the revolving of the parts herein described.
Having thus described the nature, construction and operation of my improvement what I claim as of my invention and desire to secure by Letters Patent of the United States is- The combination and arrangement of a revolving cylinder, steam-chest, cam yoke, supply and exhaust passages with a stationary cam, supply and exhaust chambers, when arranged combined and operated as herein described and for the purpose set forth.
MATTHEIV SMITH.
