To JOHN HICK, of Bolton-le-Moors, in the county of Lancaster, engineer, for certain improvements in steamengines, and in apparatus to be connected therewith, for driving machinery; part of which improvements are applicable to forcing, lifting, and measuring water."—[Sealed 5th December, 1843.] THESE improvements apply, Firstly,—to that particular class of steam-engines called "rotary engines," and consist in a novel and peculiar construction and arrangement of the working parts of the engine, which, by the application of steam, air, water, or other fluid, produce a rotary motion, with diminished friction: the engines thus made, are equally suitable for stationary, locomotive, or marine purposes. Secondly, these improvements apply to the construction of slide-valves, employed for the admission of steam into the cylinders of all steam-engines where valves are used; and consist in removing a great proportion of the pressure from the valve-face, by sustaining it on rollers or other bearings, as hereafter shewn and described, and thereby diminishing the friction of the valve. Thirdly, these improvements apply VOL. XXV. 2 D to the coupling or connecting steam-engines, or other driving power, with shafts and machinery, and disconnecting the same, in such a manner as to modify the intensity of the first impulse of the driving power; that is, gradually to transmit or withdraw the motion of a primary moving power, to or from machinery, to be started or stopped at intervals; and they consist in a simple arrangement of apparatus (which may be readily modified and adapted to suit the various situations in which it may be employed) for tightening and slackening the friction straps, or slips, ordinarily in use, for stopping and starting machinery, by a more simple and perfect arrangement of mechanism than has hitherto been employed for such purposes, and thus avoiding the inconvenience frequently arising from machinery being thrown suddenly into, or out of gear. Fourthly, these improvements apply to forcing, lifting, and measuring water, and other fluids; and consist, firstly, in the application to such purposes of a similar construction or arrangement of apparatus, to that above described, as employed for a rotary steam-engine; and, secondly, in a novel and simple arrangement of mechanism, designed to be employed as an hydrometer, or machine for measuring and registering the flow of water, or other fluids. In Plate X., fig. 1, is a sectional elevation of the improved rotary engine, with the front or side plate removed, in order to shew the working parts of the engine clearly; fig. 2, is a vertical section of the engine, taken in the reverse position, and through about the middle of the engine; fig. 3, is an exterior side elevation of the same; and fig. 4, is a sectional view of the inner cylinder detached, exhibiting the mode of packing the piston therein. a, a, a, is an outer case or annular cylinder, bored out perfectly true, having one end or side b, b, cast fast, or screwed on by bolts, as may be most convenient. c, c, is a smaller annular cylinder, occupying the larger portion of the space within the cylinder or case a, as regards its diameter, and made to fit accurately at both ends, and so placed, that one portion of its periphery is always in contact with the outer case or cylinder; to this is connected the driving-shaft d. e, e, is a loose cover, or end, which may be removed at pleasure, so as to examine the interior working Each of these order to cause parts. f, is a centre or fulcrum, round and upon which the vane, wing, or piston g, g, freely revolves, and is packed at its outer extremity with metallic or other packing, so as to prevent the escape of steam, and at its sides, in a swivelling block or packing i, i; metallic or other elastic packing may also be adapted at the sides, though it is not absolutely necessary, as the cover e, e, may be ground up, if the vane or piston is lessened by wear. In the upper part of the outer cylinder a, a, as shewn at fig. 1, are openings h, h, for the admission or exit of the steam, or other fluid. openings may be used for either purpose, in the driving-shaft d, to revolve either way; the reversing motion is accomplished by means of the slide-valvej, which is to be worked by rods and levers z, z, as usual. This valve is of further use, in preventing the steam passing from the ingress and through the egress openings at the moment when the vane or piston is moving between the two; the valve is opened and shut at proper intervals, by an excentric fixed on the shaft d. The mode of action is as follows:-Steam being admitted by the pipe k, through the opening h, acts upon such portion of the vane or piston g, as is exposed in the excentric space between the two cylinders a, and c, and thus forces the interior cylinder round, until the vane has reached the exhausting opening, when the steam is shut off by the valvej, and so remains, until the vane has passed the entrance h; the motion being kept up by the momentum previously given to the fly-wheel, which may also serve as a drivingpulley, if required. As the peculiar arrangement of the slide-valve constitutes the second feature of novelty, and is equally applicable to all steam-engines, the patentee proceeds to describe them with reference to the detached figures of the valve, which are drawn upon a much larger scale for this purpose. Fig. 5, is a vertical section, taken through part of a steam-cylinder and valve-box, shewing the slide-valve also in section; fig. 6, is a horizontal section of the valve-box, shewing the upper portion of the slide-valve, as seen from above; and fig. 7, is a representation of the interior of the valve-box, shewing the back of the slide-valve complete. a, a, represents portions of 2 D2 |
