ROTARY PUMP on TURBINE.

SPECIFIUATIN forming part of Letters Patent No. 541,455, dated J une 18, 1895.

` 'Application led January 23, 1895. Serial No. 535,973. (No model.) Patented in England July 13, 1894,11'0. 13,578.

To all wiz/m it may concern:

Be it known that I, OSBORNE REYNOLDS, a citizen of England, residing at The Owens College, Manchester, in the county of LancastLer,-England,-have invented certain new and useful Improvements in Rotary Pumps or Turbines, (for whichI have obtained a patent in Great Britain dated -July 13, 41894, No.

tion. 4

My invention relates to a construction of apparatus which, when driven by power, operates as a rotary pump, or when supplied with water under pressure, operates as a turbine,

as I shall describe, referring to the accompanying drawings.

Figure 1 is a side elevation. Fig. 2. is a plan Fig. 3 is a front view of one front view of one of the intermediate disks.

' Fig. 5 is a part front View drawn, to an enlarged scale, of one of the wheels. Fig. 6 is a transverse section, on X X' ofFig. 5, of one of theblades; and Fig. 7 is a transverse section of a modified form of blade.

I shall describe the apparatus applied as a pump. i

The casing is madeA in four parts having flanges by which they are bolted together. The first part A is made with a flange A', stiffened by side ribs A2, which is bolted down to a suitable foundation. I" has also an inlet A8 for the fluid to the first internal chamber a from which there are passages b through the partition B into the next chamber a. In this chamber there 4are radial ribs G'which prevent t-he fluid from revolving so that it Hows toward the axis passing through a central aperture b into the first wheel chamber meeting the curved parts j of the wheel blades J which project from the boss I. The wheel rotating sets the duid in rotary motion, but it is directed. by the tired spiral guides F arranged in the chamber beyond the wheel toward the second set of apertures b into another chamber a', in which another set of radial ribs G cause it to flow toward the second central aperture b to be acted on by a second wheel J and set of fixed spiral lguides F, and finally delivered through a chamber a2 to the outlet A1n the end part A4 of the casing.

The shaft S works in a bearing M formed in shaft. To this groove fluid under pressure is A conducted by a pipe P, the quantity being regulated by a cock.

The wheels are of such width as almost but not quite to touch the sides of the chambers in which they revolve, these sides as well as the sides of the wheels being faced in the turning lathe, and the bosses I of the wheels just fitting between bosses E at the centers of the chambers. The wheel bosses I are fitted on the shaft S on feather keys which are parallel, allowing the bosses I to accommodate themselves to the sides of the bosses E.

When the apparatus is employed as a t-ur-l bine, its action is 'simply reversed, the water under pressure entering at A5 and issuing at A3, the radial ribs G being in this ease dispensed with.

AlthoughI have shown on the drawings only two chambers C containing wheels and guides, there may obviously be a greater number when the pump is required to act against a higher column, or when the turbine is to be worked'by water under higher pressure.

Having thus described the nature of this Vinvent-ion and the best means I know of carrying the same into practical eect, I claim- A rotary pump orturbine, consisting of a plurality of partitioned, cylindrical chambers provided internally with fixed, spiral guides F and radial ribs G, one chamber communieating with the adjoining chamber by openings near the circumference, and the partition in each chamber having openings near the center, and a revolving Wheel in each cylindrical chamber provided with blades J, substantially as described.

In testimony whereof I have signed my name to this specilication, in the presence of two subscribing witnesses, this 8th day of January, 1895.

OSBORNE REYNOLDS.
