JOHN H. FRENIER, OF BUTLAND, VERMONT.

PUMP.

SPECIFICATION forming part of Letters Patent No. 367,803, dated August 9, 1887.

Application filed January 27, 1886.

To all whom it may concern:

Be it known that 1, JOHN H. FRENIER, of Rutland, in the county of Rutland and State of Vermont, have invented a new and useful Improvement in Pumps, of which the following is a specification.

My invention relates to that class of pumps which comprise a rotary pump-wheel formed or provided with a helicoidal passage which is constantly open and destitute of valves, and which has a receiving opening or mouth at the periphery, and from the center of which extends the discharge-opening. In the opera tion-of such a pump a volume of water is at each revolution of the wheel scooped up or taken in at the receiving-mouth, and as the wheel continues to rotate the water is raised in and delivered through the discharge-pipe.

Such pumps are desirable for raising dirty and gritty water, because they are destitute of valves or surfaces wearing one on another,and

. are particularly desirable for raising sand and water to be supplied to stone-sawing machines. The maximum efficiency, as regards the volume of water raised by a given amount of power with such a pump, can be obtained by arranging a pump-wheel to rotate in a. vertical plane; but with such an arrangement of the wheel it is necessary to connect the discharge-nozzle of the pu'mpwheel with the discharge-pipe extending upward by a stuffingbox, and the very rapid wear in the stuffingbox and consequent leakage are a source of constant annoyance and expense for repair in a pump thus arranged. v

In carrying out my invention I arrange a pump-wheel of the kind described so as to retate in a plane oblique to the perpendicularsay, at an angle of about forty-five degreesand although by this arrangement the efficiency of the pump is somewhat impaired the disadvantage is more than counterbalanced by having the discharge-pipe, which leads from the center of the wheel in an inclined direction,made continuous and connected to rotate with the wheel to the point of final discharge at the upper end of the pipe.

My invention consists in the combination of a pump consisting of a wheel and a pipe rigidly connected with its center and continuous to the point of final discharge at its upper end,

Serial No. 189,913. (No model.)

per end of the pipe, the wheel being arranged to rotate in a plane oblique to the perpendicular, with the pipe extending at an inclination therefrom, bearings for the pipe, and

gearing whereby rotary motion is transmitted to the pipe and through the pipe to the wheel. In the above combination I prefer to employ bearings for the pipe which are swiveled or pivoted transversely to the axis of the pipe, so that they may readily adjust themselves to the position of the pipe and wheel.

The invention also consists in the combination, of a rotary pump-wheel composed of a flat bar or plate coiled to form a spiral web and having at opposite edges integral spurs or projections, and parallel side. plates perforated to receive the integral spurs or projections and secured at opposite sides of the spiral web by the riveted ends of such spurs or projections, which are presented at the exterior of said side plates, and a discharge-pipe centrally connected with the pump-wheel.

The invention also consists in the combination with a rotary pump-wheel mounted to rotate in a plane oblique or inclined to the perpendicular, of a discharge-pipe centrally connected with the pump-wheel and a gate or valve in the wheel, whereby the dischargepipe and wheel may be drained of water.

In the accompanying drawings, Figure 1 is a vertical sectional elevation of a pump embodying my invention. Fig. 2 is a sectional view of a portion of the pump-wheel, taken in a plane parallel with the axis of rotation. Fig. 3 is an elevation of a pump-wheel and a -portion of the discharge-pipe, the wheel being Similar letters of reference designate corresponding parts in all the figures.

Referring first to Figs. 1 and 2, A designates the pump-wheel, which is mounted to rotate in a plane oblique or inclined to the perpenwhich the water is delivered.

dicular, and B is a discharge-pipe or hollow shaft which is rigidly connected with the center of the pump-wheel and which is continuous to the point of final discharge at the upper end of the pipe. The wheel A and pipe B are arranged to rotate in a plane oblique to the perpendicular. The wheel may be arranged at an angle of about forty-five degrees (more or less) to the perpendicular, and the pipe 13 extends at an inclination from the wheel and is substantially at right angles to the plane of rotation. The pipe B is mounted in bearings b, which may be swiveled at b, so as to readily adapt themselves tothe line of the pipe B, and at the upper end the rotary pipe may have a flaring mouth, I), through Gearing is employed for transmitting rotary motion directly to the pipe B and through it to the wheel. I have here represented a pulley, 0, upon the pipe, which may receive a driving-belt, or toothed gearing may be employed. Downward motion of the pipe B is prevented by one or more collars, b above one or both bearings I).

The punip-wheel A and pipe B form together a single continuous and constantly open or valvcless passage, provided at the periphery of the wheel with a receiving-mouth, a, and terminating at the flaring mouth-piece If at the upper end of the discharge-pipe. The wheel and the discharge'pi m throughout its entire length and to the point of final discharge I) rotate as one part, and hence in the operation of the pump there are no surfaces wearing one on another and which are exposed to sand and dirty water, asis the case where the discharge-pipe B is not continuous from the pump-wheel to the point of final discharge, but consists of a part rotating with the pumpwheel and a stationary part or section connected with the rotary part or section of the pipe by a stufiing-box.

As shown in Figs. 1 and 2, the pump-wheel consists of a spiral web, a, and parallel side plates, a, and the web is divided through the center of the pump-wheel, one-half thereof being formed integral with each side plate. The two sections of the pump-wheel,cach comprising a flat plate, a, with a spiral flange or web'sectiou projecting at right angles to its surfaces, may be secured together by bolts 11, any suitable packing material, as 8, being interposed between the sections to form a tight joint. The wheel thus constructed contains the spiral passage a which is uninterrupted and constantly open from the receiving-mouth a to the central outlet, a, with which the pipe 13 is rigidly connected. The wheel A may be rotated in a trough or box, 0, to which water or sand and water are supplied from any suitable source. In order to empty this box I have represented a discharge-pipe, c, and in order to empty the pipe B and pump-wheel A of water a dischargeopening provided with asuitable gate or valve could be employed. I have here represented an outlet-gate, f, at the side of the pump opposite the connection of the pipe B therewith. By opening this gate the water will drain from the pipe B and from the upper part of the wheel A, and then by rotating the wheel the water may be entirely discharged from the pumpwhee], provided the box or trough G is first emptied, or the pump-wheel may be employed to empty the box or trough (J, and will then, if the gatef be opened, empty itself.

In Figs. 3 and 4: I have represented a pumpwheel A which has a discharge-pipe B rigidly connected with its center, and such discliargepipe will be continuous to its point.

of final discharge at the upper end, as shown in Fig. 1, and this wheel. is composed of side plates, a, which have perfectly flat surfaces without projections, and an interposed spiral web, a. In this construction the web consists of a flat strip or bar equal in width to the desired distance between the side plates, a, and coiled in spiral form, as shown in Fig. 4. The web has at opposite edges studs or projections c flwhich are formed integral with it, and the side plates, a, have holes .or perforations which receive these studs or projections, and the outer ends of the studs or projections are riveted over on the outer faces of the side plates, a, in order to combine the side plates and the interposed web in one rigid structure.

In Figs. 1 and 2 I have represented the receiving-mouth or inletopening a as formed in a separate piece from the wheel, so that it may be readily renewed when desired. In pumping sand with water this receiving-mouth is the only part of the apparatus which is subjected to any wear other than the simple wear of the pipe B in its bearings, and hence the advantage of making it readily renewable independent of the pump-wheel.
