CENTRIFUGAL FORCE-PUMP.

SPECIFICATION forming part of Letters Patent No. 450,491, dated April 14, 1891.

Application filed May 13, 1890. Serial No, 351,683. (No model.)

To all whom it may concern.-

Be it known that we, EDWARD S. NICHOLAS and JOSEPH R. TURNER, of Greenville,in the county of Darke and State of Ohio, have invented a new and Improved Centrifugal Force-Pump, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved centrifugal force-pump, which is simple and durable in construction, very effective in operation, designed to raise light or heavy liquids, and adapted to be used for filling tanks, irrigating land, as a domestic pump, for oil-pipe lines, water-works, due.

The invention consists in certain parts and details and combinations of the same, as will be described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional side elevation of the improvement. Fig. 2 is a sectional plan view of the cone. Fig. 3 is a sectional side elevation of partof the same on the line mm of Fig.2. Fig. 4 is a sectional plan view of a modified form of the cone, and Fig. 5 is a sectional side elevation of amodified form of the improvement.

The improved centrifugal force-pump A is provided with a casin g B, havinga center wall formed in the shape of an inverted cone 0, from the apex of which extends downward the suction-pipe D, provided with a checkvalve E. The central cone 0, at its base B, terminates in an annular curved flange Q, from which extends downward the annular inner wall 0 provided with an outwardlyextending flange or base 0 The casing B is provided with a cover F, having the inverted cone G in its center, from which extends, at the circumference, the downwardly-curved annular flange G, terminating in an outer wall G reaching to the base 0 and secured to the latter by suitable means. The casing B thus formed has an inverted-cone-shaped space H, from which extends a downwardlycurved annular space 11, leading to the water-receptacle H formed between the inner and outer walls and the base, as is plainly shown in Fig. 1. From this water-receptacle H leads a discharge-pipe I.

In the inverted-eone-shaped space H is I mounted to turn an inverted duplex or hollow cone K, formed of two spaced concaved disks, and provided in its apex with a downwardlyextending short neck K, opening into the suction-pipe D, so that the water passing to the lattercan pass directly into the interior of the duplex or hollow cone K. The hollow or duplex cone is provided at its base with the curved annular ring K extending into the similarly-shaped part H of the casing B, and the said curved ring K is provided with a continuous annular outlet K discharging into the waterreceptacle H The upper conical disk or cover K of the inverted hollow cone K is secured by suitable bolts or screws to the lower conical disk or main body, as is plainly illustrated in Figs. 2 and The opening in the hollow cone K decreases from the center to the continuous opening K by reason of the difference in the angles of the two disks, said angles being on lines which intersect at the base of the duplex cone, and the area of the latter is somewhat less than the cross-section of the suction-pipe D.

The fastening-screws pass through the cover K into bosses K preferably arranged at or near the curved part or base of the cone. Between the bosses K is left sufficient space which forms port-holes or orifices, so as to leave a continuous passage in the cone from the apex to the circumference of the rim. Extra enlarged ports may be formed in the opening K to permit impuritiessuch as sand and pebbles-to pass to the outside. In

case they are used the entire discharge-opening should be slightly larger in area than the cross-section of the suction-pipe.

From the center of the cover K extends upward a hub K mounted to turn in suitable bearings G formed in the cover Got the easing B. In the hub K is secured a hollow shaft L, provided with a fixed bevel gear-wheel L, meshing into a gear-wheel N, secured on the horizontally-extending shaft N, mounted to turn in suitable bearings formed on the cover Gof the casing B. The shaft N is provided with a pulley N connected with suitable machinery, so as to impart a rotary motion to the said shaft N, which rotarymotion is transmitted by the gear-wheels N'and L to the shaft L, whereby the hollow cone is rotated within the casing B. The upper end of the shaft L is adapted to be closed by a cap L which can be removed to permit of filling or priming the cone, as hereinafter more fully described.

From the base C of the casing B leads a pipe 0, provided with a valve 0, and connected with an air-chamber P, provided near its top and bottom with valves P and P From the top of the air-chamber P leads a pipe Q, opening into the space H of the eas ing B, the said pipe being provided with a valve Q and an air-cock Q located above the highest point of the casing B.

As illustrated in Fig. t, the cone K may be provided with an interior spiral R, which commences at the neck K and terminates near the base, so that the water passing through the cone travels along the spiral before it is discharged at the opening K as illustrated in Fig. 5. The cone K is solid and is provided on its under side with a spiral It, filling the space between the hollow cone K and the cone C.

The operation is as follows: \Vhen the pump has been set up and the suction-pipe D extends into the liquid to be pumped, then the operator, in order to start the pump, first removes the cap L and then fills the suctionpipe D and the cone K with liquid. A rotary motion is now imparted to the shaft N, as previously described, so as to revolve the cone K within the casing B, whereby the centrifugalforce causes the water in the cone K to discharge through the opening K so that the vacuum produced in the cone K causes the water to rise from the wateusupply into which the suction-pipe D extends. The water 3 lifts or opens the check valve E, passes through the suction-pipe into the cone K, and is continuously discharged through the opening K of the latter as long as the cone revolves. The water is forced from the casing B through the outlet-pipe l to any desired place.

It is understood that the quantity of water sucked up and discharged by the cone K depends upon thesize of thelatterand the speed at which it revolves. When the spiral R is used, as previously mentioned, then the power of the revolving spiral is added to the centrifugal force of the cone K. When the rotary motion of the cone K ceases, the water held in the cone at the time comes to a state of rest in the cone and the latter remains filled, so

that the pump is ready to be started again at any time without a new priming or filling, as

previously mentioned. It is understood that the cone K is fitted as close as possible into the casing B, so that the cone revolves in a vacuum, whereby the friction is diminished to a minimum. It will further be seen that when the water has passed to the base of the cone K it flows downward by gravity through the curved annular part K to be discharged at the opening K into the Water-chamber H Any air which may be between the cone K and the cone C is forced outward into the water-receptacle H whenever the cone K is set in motion, as the centrifugal force moves the air in that direction.

The air-pump P is used when high pressure is desired in the casing B, so as to force the water from the latter through the pipe to a long distance or a great height. In order to do this the valves 0 and Q are opened when the pump is running, so that water from the casing B can pass through the pipe 0 into the chamber P, so as to force the air out of the latter through the pipe Q. into the top of the casing B, whereby pressure is exerted on the water contained in the casing. Now by closing the valves 0 and Q and opening the valves P and P the water in the chamber P will be drained out and the chamber again filled with air. The val-ves orfaucets P and P are then again closed and the valves 0 and Q are again opened, so that water passing through the pipe 0 again into the chamber P forces another quantity of air into the casin B, so that additional air-pressure is exerted on the body of water in the said casing. This operation can be repeated until the desired air-pressure is obtained in the casing.

By having the apex of the cone K downward, as previously described, the pump will always be filled with water ready to be started whenever desired. By providing the cone K with the annulardownwardly-extending part K the water has a free discharge from the said cone, as it flows downward by its gravity after leaving the base of the cone proper.

Having thus fully described our invention, we claim as new and desire to secure by Letters Patent- 1.
