ROTARY STEAM-ENGINE.
Specification of Letters Patent.
Application filed December 27, 1909.
Patented May 17, 1910.
Serial No. 535,118.
To all whom it may concern:
Be it known that we, GEORGE A. METOALF, WALTER C. ROCHELEAU, and LOUIS T. Roon- ELEAU, citizens of the United States, residing at WVoonsocket, in the county of Providence and State of Rhode Island, have invented new and useful Improvements in Rotary Steam-Engines, of which the following is a specification.
Our invention pertains to rotary engines, and has for one of its objects to provide a simple, inexpensive and compact rotary e11- gine, and one that is capable of developing considerable horse-power in proportion to its weight.
Another object of the invention is the provision in a rotary engine, of supporting and inclosing means, cylinders disposed therein, and pistons contained in the cylinders and connected together; the cylinders being placed together quartering, with a view of obviating difficulty in starting the engine.
Other advantageous features of the invention will be fully understood from the following description and claims when the same are read in connection with the drawings, accompanying and forming part of this specification, in which:
Figure 1 is a perspective view of a rotary steam engine constructed in accordance with our invention. Fig. 2 is a view, partly in elevation and partly in longitudinal vertical section of the same; the sectional portion of said view being taken on the line 22 of Fig. 3. Fig. 3 is a transverse section, taken in the plane indicated by the line 33 of Fig. 2. Fig. 4: is a detail transverse section taken on the line 4-4 of Fig. 2. Fig. 5 is an elevation of the main shaft of the engine, removed. Fig. 6 is a view, partly in elevation and partly in section, showing two cylinders and pistons supported and relatively arranged and connected together in accordance with our invention and in such manner that no difficulty is experienced in starting the engine from any polnt.
Referring by letter to the said drawings, and more particularly to Figs. 1 to 5 thereof: A is a suitable support having a standard a.
B is a cylinder suitably fixed in a bed I) on the support, and C is the main shaft which is suitably mounted in the standard a and cylinder B, and may be equipped with a fly wheel 0, as shown, and any other desirable appurtenances such as a pulley or gear (not shown) for use in transmitting motion from the shaft to machinery to be driven.
As best shown in Fi 3, the cylinder B contains an integral rame in which are formed a central circular chamber cl and a plurality of comparatively-small circular spaces 6; the said spaces 6 being grouped about and arranged in communication with the chamber at. It will also be observed by a comparison of Figs. 1 and 2, that the cylinder B is provided with opposite heads D and E, which are bolted together or otherwise suitably fixed with respect to the cylinder. The head D is provided with a central opening f for the passage of the main shaft C, and is also provided, about the said central opening, with a plurality of openings 9. The head E is provided with a central, lateral projection F, and in the said projection is formed a chamber it that is directly open to the interior of the cylinder, an annular chamber 71 arranged at the opposite side of the chamber h, with reference to the interior of the cylinder, and a bore j which extends outward from the interior of the cylinder to the end of the projection. In the said bore is arranged a bushing Gr having diametrically opposite ports is and also having an end flange Z that is connected by lag screws m or other suitable means to the end of the projection. The chamber it serves for the connection of an exhaust pipe H, and the chamber 2' for the connection of a steam supply pipe-I.
As best shown in Fig. 2, the portion of the main shaft C that extends through the cylinder B and the lateral projection F thereof, is hollow and is provided, in vertical alinement, with the chamber 2', with diametrically opposite ports 10, designed during the rotation of the shaft to move into and out of registration with the ports 70 in the bushing G. It will also be observed by comparison of Figs. 2, 3 and 5, that the shaft G is provided with a piston J which is preferably formed integral therewith and is of a less diameter than the chamber d of the cylinder frame, in about the proportion illustrated. Said piston J has equidistant blades 1" on its periphery, and also has ports or passages 8 each of which leads outward from the hollow portion of the shaft C to the periphery of the cylinder J at a point immediately behind one of the blades r, With reference to the direction of rotation of the piston, as indicated by arrow in Fig. 3. The piston J is also provided with passages t which extend longitudinally therein, at points about the center, and communicate at one end with the chamber h in the cylinder projection F. Each of the said passages t is connected by a port a with the space in front of one of the blades 1 of the piston.
Mounted in the circular spaces a of the cylinder frame are abutment-s K of the rolling type, which are provided with opposite recesses o desi ned to meet and permit of the passage of tie blades 7" of the piston. The said rolling or rotary abutments have stems w, Fig. 2, and on said stems are fixed spur gears a; which are preferably spaced from the adjacent cylinder head G by sleeves y. The said spur gears w are grouped about and intermeshed with a larger spur gear 2 that is fixed on the main shaft C and is preferably spaced from the cylinder head D by a sleeve a It will be gathered from the foregoing that our novel engine does not embody packing around the working parts, this being advantageous inasmuch as it obviates considerable friction and utilizes the small amount of leakage to properly lubricate the said parts. It will also be gathered that the engine is simple, compact and inexpensive and being adapted to develop considerable power in proportion to its weight, may be used to advantage in the propulsion of motor vehicles.
In the embodiment illustrated in Fig. 6, the cylinders B are identical in construction with the cylinder B of Figs. 1 to 3, and
the piston and rotary abutments in said cylinders B are similar to the piston J and abutments K of Figs. 2 and 3, with the exception that the two pistons are carried on a common shaft 0 and the alined rotary abutments are carried at the opposite ends of stems w; the said stems having fixed thereon spur gears m which are intermeshed with a larger spur gear a fixed on the main shaft C. The cylinders B are placed together quartering with a view of adapting the engine to start without difliculty from any point. It will also be observed that the cylinders B are arranged in a suitably supported casing M which holds the cylinders in position and serves to retain the heat adjacent the cylinders, and in that way prevents condensation of the steam to a considerable extent. It will also be noted that in the said casing and intermediate the cylinders B, a chamber N is afforded for holding oil in which the gears 50 and 2 work. The pipes I for supplying steam to the chambers ''of the two cylinders, arepreferably connected with a pipe I for leading live steam from a suitable source of supply,
while the pipes H for leading exhaust steam from the chambers h of the cylinders, are preferably connected to a pipe H designed to lead to a suitable point of discharge.
lVhile we have shown and described two forms of our invention, it is to be understood that we are not limited to the details or the form or relative arrangement of parts disclosed, but that modifications may be made therein without departing from the spirit thereof.
