SPECIFICATION forming part of Letters Patent N0. 764,756, dated July 12, 1904.
Application filed April 19, 1904. Serial No. 203,899. (No model.)
To ftZZ whom, it iVm/y concern.-
Be it known that I, `WrLLiAM Gr. NICOLA, a citizen ofthe United States, residing at W'ashington, in the county of Vashington and State of Iowa, have invented certain new and useful Improvements in Rotary Engines; and l do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which forni a part of this specification.
This invention relates to new and useful improvements in rotary steam-engines; and the object of the invention is to produce an apparatus of this character in which a pressure of live steam is constantly exerting its force upon one section or another of a rotary cylinder while exhaust is taking place at one part of the cylinder or the other.
The invention consists, further, in various details of construction and combinations and arrangements of parts, which will be hereinafter fully described and then specifically deiined in the appended claims.
My invention is illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this application, and in which- Figure 1 is an end elevation of my improved rotary engine. Fig. Q. is a sectional view through the cylinder and casing, and Fig. 3 is a sectional view-on line 3 3 of Fig. 2.
Reference now being had to the details of the drawings by letter, A designates the casing of the engine, which is made up, preferably, of two sections securely bolted together and supported upon legs A'. A shaft B is journaled in'bearings B, mounted upon the legs C. Said casing is provided with two steam-inlet ports D at one end thereof, which open into a chamber E, which chamber has a series of ports E, which pass through the inner face of the cylinder at angles, as shown. Having reference to Fig. 3 of the drawings, it will be seen that the steam-chamber E passes substantially the length of the casing and has the ports E' leading therefrom, which are adapted to communicate successively with the steam-pockets F in the cylinder F', which is keyed to rotate with said shaft B. Each of said pockets F has a contracted neck portion F2 opening through the circumference of said cylinder and is adapted to come alternately into registration with a steam-port and an exhaust-port K. The exhaust-ports, which are positioned intermediate the steam-ports, open into the exhaustchamber, (illustrated by letter N, Fig. 3,) and exhaust-pipes O lead from said chamber, as clearly shown in the drawings. In order to make the steam-tight joint between the rotary casing and the cylinder, packing-rings Q are provided, which are seated in an annular groove in the circumference of the ends P of the cylinder, and the curved segments of the cylinder (designated in the drawings by letter S) are made up of separate sections S2, dovetailed together, so that steam-pressure on the interior of the cylinder may press these parts of the cylinder against the inside of the casing, thereby making a steam-tight surface between the cylinder-drum and the cylinder. 1n order to make a more effectual steam-tight connection, steel rings T are provided, which are seated in the ends of the cylinder and bear against the sections S of the rotary cylinder. Leading from each of the steam-pockets is a drain-port L, whereby any condensed steam may make exit into a port L in the casing about the cylinder when not in use.
By the provision of a rotary engine made in accordance with my invention it will be 0bserved that live steam is being constantly fed into the pockets of the rotary cylinder through one or another of the steam-ports, while exhaust is permitted through one or another of the exhaust-ports, and by the arrangement of the ducts the pressure of the live steam is exerted upon the rotary cylinder during the interval that the opening in the steam-pocket passes from one steam-inlet port to an exhaustport, thus utilizing the full force of the steam.
While I have shown a particular detailed construction of apparatus illustrating my rotary engine, it will be understood that I may vary the detailed construction of the engine, if desired, without departing from the spirit of the invention.
IOO
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is*
l. A rotary engine comprising' a cylinder having a live-steam chamber therein with inclined ports leading therefrom through into the interior of the casing, a shaft, a cylinder keyed to said shaft and rotating in contact with the inner surface o'f said casing, said cylinder having a series of steam-pockets having ports opening through the circumference of the cylinder, the outer wall of each of said pockets made up of sections, an exhaust-chamber with exhaust-ports disposed intermediate lthe steam-inlet ports, and so arranged that steam may be continuously admitted to the steam-pockets simultaneously with the eX- haust of the steam-pockets, as set forth.
2. A rotary steam-engine comprising a casing having a live-steam and an exhaust chamber therein, a shaft passing through said casing and mounted in suitable bearings, a cylinder rotating with said shaft and in contact with the inner surface of said casing, and provided with a series of sections forming the outer walls of steam-pockets, with ports opening4 through the circumference of the cylinder, exhaust-ports leading radially into the eX- haust-chamber and live-steam ports leading through the easing tangent to said cylinder, with the live-steam feeding and exhaust ports alternately arranged, as set forth.
3. A rotary steam-engine comprising a cylindrical casing with a hollow center and provided with a live-steam and an exhaust chamber, exhaust-ports leading from the exhaustchamber radially and opening through the inner wall of said casing, a shaft passing through said casing, a cylinder rotating with said shaft in contact with the inner surface of said casing and provided with a series of steam-pochets having ports opening through the circumference of said cylinder, the outer walls of said pockets made up of sections having dovetailed connections, said live-steam chamber having series of tangential ports leading through the inner wall of the casing and alternately arranged with said exhaust-ports, cylinder ends, suitable packings between the same and said casing, and packing-rings intermediate the sections of said cylinder, as set forth.
4. A rotary steam-engine comprising a casing having a live-steam and an exhaust chamber therein, a shaft passing through said casing and mounted in suitable bearings, a cylinder rotating with said shaft and provided with a series of sections forming steam-pockets, the outer wall of said pockets being made up of sections which are dovetailed together, steam-ports opening through the circumference of the cylinder, exhaust-ports leading radially into the exhaust-chamber and livesteam ports leading into the casing tangent to said cylinder, said live-steam and exhaust ports alternately arranged, as set forth.
In testimony whereof I hereunto affix my signature in presence of two witnesses.
WILLIAM G. NICOLA.
