.CONSTRUCTION OF ADJUSTABLE BEARINGS OR BOXES FOR EMBRACING AND SUSTAIN- ING THE SHAFTS OF VVATER-WHEELS, 86C.

Specification of Letters Patent No. 2,446, 4dated February 7, 1842.

ToaZZ whom 25 may concern:

v Be it known that I, CHARLES JOLY, of the city of New York, in the State of New York, have made certain improvements in a vmach-ine for raising and for applying water-to various useful purposes, which ma- Reproductive hydraulio machine which consists of a comybned centrifugal pump, and hydraulic step;

and I do hereby `declare that the following is a full and exact description thereof.

Thev part of my machine which is to be used for the raising of water from a cistern, or reservoir, isa modicat-ion of the apparatus yknown vunder the name of the cent-rifugal pump, which I have so improved as to cause'it to operate with less friction than under any of the modes of construction heretofore adopted. The centrifugal pump may be varied in form, but that which I have given in Figure l of the accompanying drawings will serve to exemplify the action of Ymy improved machine. In this figure, the left `hand half of the drawing represents oneh-alf of the main vertical shaft, and one of the tubular horizontal and vertical arms through which t-he water is raised, as they appear externally; together with certain parts appended thereto; and the right hand half of the same figure represents them in a vertical section through their axes; there is a wall, or other firm structure, which may be built circularly upon a secure basis; and into 'the lower part of the circular space thus formed, the water which is to be raised is admitted from any convenient source, this water occupies the situation marked X2. The water when raised by the centrifugal action of the machine, is to be delivered into a circular trough u, u, supported by the wall; at u there is a gate or opening allowing the lwater to escape from the circular trough for the purpose of being applied .as a motive power to a wheel or other suitable apparatus. n

At d, the tubes or pipes through which the are connected together, and from this part they may be said to form three branches; the mast a, a section of which is shown at X, rises vertically from the reservoir of water, into which its lower end opens; and t-he two portions c, 0 proceed from it horizontally, and are connected by the curved elbows b, b, with the vertical pipes 2, i; `the curved portions j, y', attached .to these, serve to deliver the water which is raised into the trough u, u. The capacity ofthe pipe a should be at least double that of either of those marked c, c as it supplies bothof them; this centrifugal pump is represented as composed of several sections. .Between the sect-ions f f and g, g, there are Valves at e, c opening upward and allowing, when open, a free passage to the watern The respective sections are to be fastened together by means of flanches and screw bolts, or in any other convenient way.

h, L, are tubes which enter the pipes i, z', above the valves e, e; these tubes both co nect with a single supply tube, and force pump, by which the tube z', i, are to be filled prior to putting the machine into operation. A vertical shaft Z, Z, rises from the tube a, and has at its upper end a gudgeon 1', 1", which is received, and runs within a suitable socket or box in the frame work of .the machine.

y, y, are cords attached to valves or shutters, which close the mouths of the tubes I, I, when the machine is at rest, said cords passing over pulleys at P, and being acted on by a weight at n. At E, E, there are collars and flanches from which eight arms K, K proceed radially; two of these are made to sustain-the tubes z', z', and the whole of them extend out to a cylindrical case c, Ze', which is attached to, and revolves with, said pipes; said cylindrical case should be made very true, and with a polished surface `to .enable it to revolve with little friction from the air.

E, Plate l, is a side view of two of these arms 7c, 7c, E a section through them, and E2 a top view of the whole series. In these and in the other' parts which are represented in detail and which will be presently described, variations may be made without altering the nature of the combination, or the principle of action in my machine; and I do not intend therefore to limit myself to the particular forms given, but present them only as exemplications of the means which may be advantageously adopted for connecting the respective parts. I have already intimated that the form of the pipes z", z",

may be varied; and they also may be increased in number if desired. The ascending pipe u; may for example, be extended up in the direction of the shaft Z, Z, to the height to which Vthe water is to be raised and those which deliver the water into the circular trough may branch off from it horizontally, at its upper end which will give to this part the form of the letter T, a form which has sometimes been given to them.

The main vertical shaft Z, Z which may consist of a hollow pipe of cast-iron is connected to and rests upon, a solid shaft V, shown separately at the two being united by means of fianches. The shaft V passes through the center of the tube a, and its lower end rest-s upon, and is coupled to the shaft L, L through which the first motion is to be communicated to the machine, in a manner to be presently explained. To prevent the escape of water from the reservoir, alongside of the shaft V a tube Z, attached to the bottom of the reservoir arises therefrom to a height above the surface of the water, and is surroundedV by a tube Y attached to the revolving arms. 1

I will now proceed toV describe the manner in which I construct the hydraulic step of my machine consisting of the lower gudgeon, and the box within which it runs. A, is a block, or support of cast iron; which may be formed as shown in section at A, and in top view at A2 Plate 2.

B, is a stout cylindrical step, which receives the lower end of the shaft L L, constituting the lower gudgeon. This, in Fig. l, is represented as resting upon a point 0, but it is not to be so sustained when the machine is in action, but is to rest entirely upon a iuid; oil being preferred for that purpose. At B', Plate 2 this cylinder is shown in section. v

B is a side, and B2 a top view of it. This cylinder is surmounted by a stufling box; C being its lower and D vits upper part. These are shown enlarged in Plate 2 at C, C and at D, D and D2.

U is a force pump from which oil is to be forced through the small tube T into the chamber of the cylinder B and this fluid being confined by the stuliing box will raise the shaft L and cause the whole weight Vof the superincumbent machinery to be sustained upon a bearing of oil alone; the por tion of oil which. percolates through the stuffing box may be conducted back again to the force pump by the tube S.

To sustain the shaft L, L and the shaft or gudgeon 7', 0", at the upper end of the main shaft, I surround them by adjustable bearings contained within suitable boxes at the points F, F, F. The mannerV in which I construct these boxes is fully represented at FG and H Plate 2.

G G and G2 are sliding nuts constituting the bearing of the shaft, andwhich may be jointed, as represented, which are to be Y borne upV against the shaft, and these are seen in place at H H, H2; the section F,

6 5 and these-perspective view F, represents aV rotating cap, which constitutes a part of these boxes H and is sho-wn in place at H H, and H2. By rotating the portion F it will be seen that the nuts Gr Gr will be regularly forced up by the four inclined curves on the inner side of said rotating cap. The upper box F Plate 1, is sustained on the frame work above the centrifugal revolving arms.V The upper 'one on the shaft L is supported upon an iron bench, or standard, I, I, attached to the frame work under the reservoir of the machine, and this is shown enlarged aty I I I2, Plate 2, as having three branches by which to attach it; the form of this particular may of course, be varied at pleasure to suit that of the frame work.

K, K is a second support of iron, with three branches also by which to attach it to the frame; and this serves to support the machine when not in motion. The shaft L, L, may have a range of five or six inches, vertical play, resulting from the varying quantity of fluid forcedl in under it, although a height of half an inch, or less, of oil will be as effective as a larger quantity.

At B, Plate 2, two tubes are represented as entering the chamber of the cylinder; one of these is for the supply of oil, the other may lead to a manometer, and indicate the total pressure of the machine. Upon the shaft L, L there is a toothed wheel M, having a wide rim, say of eight or ten inches in width, to allow of its vertical play. Into this gears a wheel N on a vertical shaft, carrying also a bevel wheel P; into which latter the bevel wheel Q on the horizontal shaft R engages. When from peculiar circumstances the apparatus just described cannot be allowed the requisite space below the reservoir the oil pump may be elevated to the level of the reservoir, and the cylinder B constituting the step of the machine, may be placed within the reservoir itself, the other parts being adapted to this arrangement; the manner of doing which will be readily perceived by every competent machinist.

'lVhen the machine is to be set into operation the pipes z', c', are to be first lled with water which may be done through the tubes 71 li, and oil is also to be forced into the cylinder B. Motion is then to be communicated to the centrifugal pump by any extraneous power applied to the shaft It, until itv has acquired suflicient velocity to cause the water to rise freely into the trough u, u. This water upon being allowed to escape at the gate u may be made to turn a bucket 'wheel and the power thus generated may be the centrifugal pump as of my invention ing nuts and the rotating cap, with its inths having been long known and used but clned curves, arranged and operating as 10 What I do claim sset forth.
