GEORGE WILSON, OF WESTMINS'IER, ENGLAND.
SPECIFICATION forming part of Letters Patent No. 243,744, dated July 5, 1881.
Application filed July 13, 1880.
To all whom it may concern:
Beit known that I, GEORGE WILSON, ot Parliament Street, in thelcity ot Westminster, England, have invented an improved Apparatus for Forcing or taising Water, and also for other purposes, (for which l have obtained a patent in Great Britain, No. 4,733, bearing date November 20, 1879,) of which the following is a specification.
My invention consists ot' a wheel inclosed in a casing and capable ot' being rotated by steam or other power, this wheel and casing being so arranged that there is a cavity or channel (or cavities or channels) between the periphery ofthe wheel and casing, this waterpassage between the Wheel and casing extending partly but not completely around the wheel, and communicating at one end with a supply pipe or conduit and at the other end with an exit pipe or conduit, as more particularly hereinafter described.
The apparatus consists of what I term a Wheel having a cavity or cavities sunk in and extending around its periphery. The transverse section or sections of' the said cavity or cavities sunk in the periphery of the wheel may be formed of parabolic, circular, elliptical, or of any'other curves, either concave or convex or partly concave and partly convex; or the form may be angular or partly angular and partly curved. The Wheel is inclosed and caused to revolve around its axis Within an airtight casing. The Hat ends or sides of the Wheel revolve close to the sides of the casing; but the portion of the casing inclosing and extending around the periphery of the wheel may be a plain surface or concave or convex, of a circular, elliptical, parabolical, or of any other shape. The suction and discharge of the water respectively to and from the Wheel is through a passage or passages inthe casing at the periphery. The Waterilows through the samepassages Whichevermay be the direction the wheel is caused to revolve; but the suction and discharge passages for the water to iiow through when the' wheel is caused to revolve in one direction respectively become reversed, or discharge and suction passages when the wheel is caused to revolve in the contrary direction.
Theac'tion of the apparatus is as follows: The air-tight casin ginclosin g the wheel and also (No model.) Patented in England November Q0, 1879.
the suction-pipe being full ofwater, (in a siniilar manner to an ordinary centrifugal pump,) the wheel is then caused to revolve by steam or any other power with the requisite velocity in the desired direction, and the action ofthe cavity or cavities sunk in the periphery of the revolving wheel upon the water causes the latter to be forced by friction, or by friction and suction, round in the direction the wheel revolves, through the apparatus and discharge pipes or passages.
My said invention, besides being applicable as a pump for the purpose of lifting or forcing water or other iiuids, is also applicable for forcing water out of the stern or other part of a vessel in any desired direction for propelling the saine, or out oi' the side or sides ofthe vessel for steering the same.
In order that my said invention may be clearly understood, I will now give general illustra tions of the saine.
Referring to the hereinbefore description and to the drawings hereunto annexed, Figures l and 2 are sections through the apparatus, in which one cavityis sunk in and extends around the periphery oi' the wheel. The solid thick black lines show the wheel, which revolves on the axis g r/ on bearings It h. m m is the casing inclosing the wheel, and o is the cavity sunk in the periphery ofthe wheel.
Fig. 3 is a section of a wheel in which four cavities, o o, are sunk iu its periphery.
Fig. 4 shows a section of a Wheel the cavity or cavities of which are partly angular. Supposing that the wheel is caused to revolve in the direction shown by the arrow s, the water Will iiow through the suction pipe or pipes at F and enter tangentially the cavity or cavities of the Wheel at Y, and ,after bein g forced through the apparatus by the frictional action ot' the revolving wheel, the same will enter tangentially atYand be discharged through the pipe or pipes at G. If the Wheel is caused to revolve in a contrary direction to that hereinbefore lastly described, then Gbecolnes the suc tion and F the discharge pipe or pipes for the water. The casing is formed in such a manner, as shown at Y Y', that in either direction in which the wheel is caused to revolve the Water forced partly around the casing by the action ofthe revolving wheel ows tangentially from IOO the suction pipe or pipes into the cavity or cavities of the wheel, and also tangentially from the latterinto the discharge-pipe or pipes. The distance betweenY and Y-the tangeutpoints `for the entrance and discharge of the water into and from the cavity or cavities of the wheel-is dependent on the desired arrangement of the suction and discharge pipes with regard to the casing.
Fig. 5 shows the suction and discharge pipes H J (one of which is shown straight and the other curved) arranged in such a manner that the water will be acted upon bythe revolving Wheel and forced round the casing through the distance of a semicircle.
The suction and discharge pipes and also the apparatus should be constructed in such a manner as to cause the water to 110W in continuous volumes of uniform or nearly uniform sectional areas.
In the application of my improved apparatus as a pump for the purpose of lifting or forcing Water or other fluids, one of the pipes, G or F,
would be the suction and the other the dis charge pipe for the Water, the arrangements being as for ordinary centrifugal pumps. This pump can also be used for propelling or steering vessels by forcing the Water from the stern or other part in various ways.
Having thus fully described my said invention and the manner of performing the same, I wish it to be understood that I claim- My im proved apparatus,consistin g ofa wheel iuclosed in a casing and capable of being rotated by steam or other power, the wheel and casing being so arranged that there is a cavity or channel (or cavities or channels) between the periphery ofthe Wheel and the casing, extending partly but not completely around the Wheel,V
and communicating at one end ,with a supply pipe or conduit and at the other end with an exit pipe or conduit, substantially as described.
