STEAM 0R WTER MOTOR.
SPECIFICATION :forming part of Letters Patent No. 373,922. dated November 29, 1887, Application filed August 1D, 18557. Serial No. 246,561. (No model.)
To aZZ whom, it may concern:
Be it kn'own that I `J OEL T. CASE, a citizen of the United States, residing at Bristol, in the county ot" Hartford and State of Connerticut, have invented certain new and useful Improvements in Steam on Water Motors, of which the following is a specification.
My invention relatesto improvements in steam or water motors, and the objects of my improvements are to improve the construction and eftlcieney of the machine and to provide a construction which is applicable either to a steam-engine or a water-motor.
In the accompanying drawings, Figure lis a vertical section of my engine, partly in elevation, the plane of section being indicated by the line z z of Fig. 2. Fig. 2 is a vertical section thereof, partly in elevation, on line .r x of Fig. 1. Fig. 3 is a detail view showing the steam-chest at one side of the case with its cap removed; and Fig. 4 is a horizontal section,partly in elevation,on line yy of Fig. 2.
This invention isV in the nature of an improvement upon the engine shown and described in my application No. 241,094, led June 13, 1887.
Although the construction herein described is adapted for either a steam or water motor, I shall for convenience describe its construction as a steam-motor'.
As in my aforesaid application, I prefer to make the case or frame A in the form of a shafthanger and provided with a cap, B, for covering one of its broad sides.4 The two broad sides of its case or frame -also serve as plates for closing two sides of the steam cylinder or box C, which cylinder-is also fitted to and oseillates and reeiprocates on the central rocking block or piston, D, substantially as in my aforesaid application. Instead, however, of mounting the rocking block or piston upon a hollow axle through which steam passes, I mount it upon a solid axle or shaft, a, preferably made a little tapering to compensate for Wear,and provided with adj usting-nuts b b,.by which it is secured to and adj usted within the box or frame A.
In order to somewhat enlarge that surface of the .cylinder or steam-box which works against Athe broad side of the case, I provide the same with flanges c.`
In each broad side of the case A and on that surface which is traversed by the steam-cylinder or box C, I provide four ports, d d and e e, their position being indicated by broken lines Wherever they are hidden from view by other parts. These ports open into small steamchests f f and g g on the outside of the case proper, which chests are covered by the caps h. The chests f f,on opposite sides of the case, are connected by a passage-Way, k, so that a steam-pipe (indicated by broken lines at E) in one of the caps h, for supplying steam to one chamber f, will also supply steam to the opposite chamber through the passage. Inlike manner the chests g g are connected by a passage, Z, so that exhaust-steam may pass from both chests out through the discharge-pipe F.
In order to increase the bearing-surface between the rocking block or piston D and the cylinder or steam-box mounted thereon, and also to elongate the ports d d and e e, I provide the piston with anges m mand the ends of the cylinder or steam-box C with correspondingly-shaped recesses, as shown most clearly in Fig.'1. In order that these anges may not obstruct the ports, I make them a little shorter than the thickness of the case on its inside, so that, as sho'wn in Fig. 3, they do not bear against the sides of the case.
The reciprocating and oscillating cylinder and steam-box C is connected by means of any suitable connecting-rod, n, Fig. 1, with the crank-pin o ofthe shaft G.
With the parts in the position represented in Fig. 1, and with steam admitted at E into the steam-chests f f, the steam will pass in' through the lower ports, d, thereby forcing the cylinder or steam-box C downward and driving the crank-pin o in the direction indicated by the dart in Fig. 1. At the same time exhaust-steam will be passing into the steamchests g g through the upper ports, e, and out through the exhaust-pipe F. As the crank and cylinder travel onward these ports are both gradually closed until the crank-pin o is at the bottom of its motion and in the same vertical plane as the center of the axle a. At this point all of the ports will be closed; but so soon as the crank-pin passes this point steam will pass inv at the upper ports, Land exhaust-steam out of the lower ports, e, thereby driving the ICO cylinder in the opposite direction until the crank pin 0 reaches its highest elevation and begins to descend to again open the lower ports, d, and upper ports, e, and so on repeatedly. By this construction the ports can be enlarged to admit and discharge a great quantity of steam, thereby running the engine at a high speed and furnishing it with all the steam that is desired. Iain also enabled to so arrange the ports that a very little movement ofthe crankpin Will carry the eylinderinto position to reverse its movement. ln other words, there is only a very small portion of the travel of the cylinder in which all the ports are Closed.
While I have described the stealn as adinitted at E and the discharge of the exhauststeem at F, the direction of the steam may be reversed. The result of snoh a change. suppos inagthe parts to be in the position shown i'n Fig. l, would diii'er from that before described only by driving the cranl pin o inthe opposite direction from that indicated by the dartin said ligure.
The same construction is applicable to water-motors; but inasmuch as water is non-conn pressi-ble, the confronting edges of' the ports c and d would be Carried inward a little-that is, toward each otherwso that they would not be quite closed when the cylinder is in a vertical position.`
I claim as my inventionl. The combination of a central lrocking block or piston, the opensided cylinder or steam-box mounted thereon, and the frame or ease covering the open sides ofthe cylinder and provided with outlet and inlet ports located within the path traversed by said cylinder7 substantially as described, and for the purpose specified.
2. The combination of the rocking block or piston, the opensided cylinder or steam-box mounted thereon, the ease covering'the open sides of said cylinder and provided with inlet and outlet ports, the steam-chests on opposite sides of the case and outside of said ports, and a eonneetingpassage for uniting said steamchests, substantially as desoribed,' and forthe purpose specified.
