WILLIAM D. "ANDREWS, or NEW YORK, N. Y.
` CENTRIFUGAL `PUMP.
Specification `of Letters Patent `1\To. 11,544, dated August 22,-1854.
y of the same, the `planeA of section beirrg through the center." The flanched `conical rotating hub within the case is not bisected. Fig. 3,`is a viewof the interior of the lower part of the case showing the stationary hub,
having a socketin which the lower end of the shaft of the rotating hub revolves, and showing the spiral induction passages between the outer shell and stationary hub. In this view, the rotating hub is` removed. Fig. l, is an interior view of the upper portion of the case, showing the spiral eduction passages. 1
Similar letters of reference indicate corresponding parts in the several figures.
The nature of my invention consists, in having a hub in `the form of an inverted cone with its apeX removed, having one or `more radial arms or flanches attached longitudinally to its circumference, and decreasing in width as they approach the base. The said hub being placed within a caseclosely fitting it at `top and bottom and the outer circumference of the arms, and having induction passages of a` spiral form with a gradually decreasing pitch,l causing the water to pass from a straight line in the pipe below, by a gradually increasing spiral course to the -point where it is acted upon by..
the arms upon the rotating hub in its line of,4 direction, and by the centrifugal force thereby imparted,l passing by the eduction passages gradually from a spiral again to a sary friction and loss of power attending the changing the direction of the water at an angle, as in centrifugal pumps nowin use.
To enable others skilled in the art to make and use my invention, I will proceed to describe its construct-ion and operation.
A, represents the lower portion of the case of the pump, which is of a conical form, as clearly shown in Figs. l and 2. In the lower end of the case, A, is a conical sta tionary hub, C, as clearly shown in Fig. 2,
having a socket in which the lowest end of the shaft, D, revolves;` 01,2131 pi-@fer ini practice, a stationary point may project above the hub, C, fitting into a socket in the end of the shaft, D. This hub, C, is secured. to the outer case A, by their `flanches, b, as shown 1n Figs. 2, and 3, decreasing in pitch as they approach the top, (or base). The'` shaft, D, has secured upon it the hub, E, in the form `of a conc, with apex reinoved, `so
that the diameter of its lower or smaller end shall be the sameas the base or upper part of the stationary hub, C, ofwhich itis in shape `a continuation, the angle of eachbeing slightly greater to the center than that of the case, A,causing themto converge and making the space between both the conical hubs, C, and E, and theouter case, A, narrower as its circumference increases, thereby making `the differentsections of the space or passage, of the same, or `nearly the same area. One or more thin flanches or arms,ia, l
Fig. 2, are secured longitudinally upon the periphery of the rotating conical hub, E, and extend radially to the outer case, A, as nearly as possible without touching, and longitudinally from the lower end of the hub, E, to a short distance above its upper end, until they intersect a line drawn across the upper edge of the lower case, A, and terminating in a point, formed by their ends being made parallel to the shaft, D, as shown in Fig. 2. The lower ends of the arms are formed at right angles to the shaft, D, and on a line with thebottom oft-he hub, E, as shown in Fig. 2. i
`F, representsthe upper portion of the outer case secured to the lower portion,`a, by flanches, I, I, and bolts, d, Fig. 2, and
havingattached to its upper surface a spiral sage, c, into the passage within the case, A,
and occupy the entire space radially, not swept by the arms, a, a. The shaft, D, passes through a stuffingbox, I-I, Vsecured upon the to hub, E, and arms, a, which, by the centrifugal force, Will causeV the Water to flow up the spiral passages formed by the flanches, e, into the pipe, Gr, and thence through suitable pipes as occasion requires. Discharging the contents'creates a vacuum Which is immediately supplied by Water rushing in through the induction pipe and spiral passages formed by the spiral flanches b, hub, c, and case, A, the Water passing through the pump in one continuous unbroken volume in an easy spiral course, and having the same area in allits sections, thereby avoiding all sudden turns and eddies, incident toa different construction. It-must be understood that the induction ipe is to be secured to the lower end of case, A, by the flanch, f, and suitable bolts, care being always taken to have the induction pipe of the same area as the induction passages to avoid eddies in the same.
l/Vhat I claim 'as my invention, and desire to secure by Letters Patent, is:-
yThe construction of the pump as herein described and shown, viZz-I-Iaving a hub, E, in the shape of the base of a cone inverted, with arms, c, attached to its periphery, of a gradually decreasing Width as they approach its base, placed Within a shell corresponding in shape to the outer circumference of the arms, and having induction passages ofv a spiral rm gradually decreasing in pitchv to their point of delivery, and educt-ion passages of a spiral form of a gradually increasing pitch, until they attain a straight line. By Which construction the Water is made to pass Without sudden change of direction or eddies, in an unbroken volume through the pump. And I do not limit myself to the precise mechanical construction as shown, but may modify the different parts, only retaining the same general combination.
