WATER-ELEVATO R.

SPECIFICATION forming part of Letters Patent No. 565,800, dated August 11, 1896. Application filed April 4, 1895. SerialNo. 544,461. (NomodeL) To all whom, it may concern.-

Be it known that I, DETALMO DI BRAZZA SAVORGNAN, of Rome, Italy, have invented a new and Improved .Water-Elevator, of which the following is a full, clear,and exact description. p

The object of my invention is to construct a water-elevator without cylinders, pistons,

or piston-rods, for deep wells, mines, and ex- IO cavations, in which the natural pressureof the atmosphere will be utilized in raising the water. 7

My invention consists in a series of chambers provided with supply and discharge pipes and valves and afloat-operated mechanism for opening and closing the valves, all as will be hereinafter more fully described.

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 views.

Figure 1 is a side sectional elevation of one of the water-elevating chambers. Fig. 2 is a side elevation of a series of such chambers connected with each other and with the vacuum-pipe. Fig. 3 is a side sectional elevation of a modified form of vacuum-chamber. Fig. 4 is a side elevation of a series of such chambers connected together. Fig. 5 is I a side sectional elevation of another modification on the line 5 5 in Fig. (3. Fig. 6 is a partial horizontal sectiontaken on line 6 6 of Fig. 5. Fig. 7 is a vertical transverse section of another modification. Fig. 8 is a side elevation of a series of such vacuum-chambers, and Fig. 9 is a modification of the form shown in Fig. 1.

The chamber A is divided into three compartments B C D, with a passage E at the side of the chamber communicating directly and continuously with the compartment B through the opening a, and communicating through the inclined valve-openin g b with the compartment D. The compartment B communicates through the short U-shaped pipe 0 with the compartmentC, and the upwardlyturned end of the said pipe 0 is furnished with a check-valve d, opening upward. In the wall of the compartment C is formed a slot 6, through which water may overflow into the compartment D, and the compartment G communicates with the compartment D through the valve-opening f in the bottom of the compartment. The valve-opening f is closed by the valve g, which is attached to a curved arm 72., pivoted between ears 2', secured to the floor of the compartment 0. A stem j extends from the valve 9 downward through the val v e-opening f into the compartment D. p l

In an upward extension 74; of the compartment D is placed a weighted valve-carrying arm Z, which is bent at right angles and attached to a. valve m,.adapted to close the valve-openin g n in the side wall of the upward extension of the chamber D. The angled arm I is pivoted in a bracket 0, extending inwardly from the wall of the compartment D, and the said arm is furnished with a finger p, projecting into the compartment D at right angles to the pivoted end of the arm.

In the upward extension q of the compartment D, communicating with the valve-opening 19', is placed a vacuum-valve 1", which is attached to a curved arm 5, pivoted in the bracket 15, projecting from the wall of the compartment D. The arm 5 is provided with a finger u, projecting at right angles toward the center of the compartment D. The arms Z and s are provided with weights which serve to hold the said arms and valves attached to them in either an open or closed position.

In opposite sides of the compartment D are supported tubes c a? by brackets 19, attached to the wall of the chamber A. The said tubes a a form guides for the float F. The float F is furnished with cars a, two on either side, the apertures of which are prolonged to permit of the tipping of the float in the opera tion ofthe apparatus, as will be hereinafter described. In the tubes a a are placed the rods d (1 The rod d extends downwardly toward the bottom of the chamber A and is bent twice at right angles, the end of the rod extending upward toward the float F. The

similar way the lower end of the rod (1 extends upwardly toward the float F, and the upper end is furnished with an angled arm 6 extending downwardly toward the floatF and provided with lugs f which embrace the finger p of the valve-arm Z.

The chambers A are arranged one above the other in a series, the distance between them being about equal to the distance through which a pump can draw water. The top of each chamberis connected by a curved pipe g with the vacuum-pipe G, which extends to a suitable vacuum-pump. The bottom of each chamber A is connected by a pipe H with the top of the next chamber above.

In the modification shown in Fig. 3 the chamber A is divided into two compartments 0 D, and the compartment 0 communicates with the compartment D through a slot 6 in the partition which separates the upper portion of the chamber A into two compartments. In the chamber A is secured a tube a which extends through the compartments CD, but does not communicate with the compartment 0. On the tube a is placed a centrally-apertured float F, and in the tube a is placed a rod d having its lower end bent at right angles and projecting through a slot in the side of the tube a below the float F. The rod 01 is provided with an arm 8 which projects through a slot in the tube 603 above the float F. The upper part of the rod 01 carries a valve m, which closes an opening at in the top of the casing, which is coincident with the bore of the tube a The upper end of the rod d is provided with two lugs f. In a standard 0, projecting from the top of the casing, is pivoted a right-angled lever 19, the shorter arm of which extends between the lugs f of the rod (i and the longer arm. of the said lever carries a weight which swings to one side or the other of the center of movement and holds the lever in either of the two positions in which it may be placed.

In the horizontal partition between the compartments O and D is formed a valve-opening f which is closed by a valve 9 attached to a curved arm k pivoted between ears 7?, projecting upwardly from the floor of the compartment. The valve g is furnished with a stem j, which extends downwardly toward the float F. A pipe II communicates between the bottom of one chamber, A, and the top of the next chamber above in the series, and each pipe I-I near the bottom of the chamber A is furnished with a check-valve I opening upwardly.

In the modification shown in Figs. 5 and 6 the construction is similar to that shown in Fig. 3. Therefore the same letters of reference will apply to like parts. In the said modification the lower portion of the chamber A is extended downwardly and the rod d and tube a are extended downwardly, the rod (1 being provided with a pair of lugs e e. The lower end of the pipe H in this case is forked and the branches k k communicate with the lower part of the chamber A through valve-openings Z Z which are on the same level. Angled levers m m pivoted in ears projecting inwardly from the side of the easing, carry valves 91 n adapted to close the valve-openings Z Z The free ends of the levers m m extend between the lugs c e, projecting from the rod (1 and the levers are oppositely arranged with respect to each other.

In the branch of the pipe II is placed a ball 0 which is slightly heavier than water, and the mouth of the branch 7 3 opening into the chamber A, is provided with a wire-cloth guard 19 The branch 70 of the pipe H at its juncture with the said pipe is provided with a wire-cloth guard g for preventing the ball 0 from entering the said branch, and the upper end of the pipe H is provided with a similar guard g for preventing the ball from going into the next chamber above.

The modification shown in Figs. 7 and 8 differs from the form shown in Fig. 1 in the omission of the compartment B, the U -shaped pipe 0, the valve 61, and pipe G, and in connecting the passage E with the pipe 11 by the pipe G.

In the modification shown in Fig. 9 a waterreceiver 0 is formed on the top of the float F and a valve-opening f is formed in the side of the water-receiver and closed by a valve 9 carried by the valve-lever 72, pivoted to an arm projecting inward from the wall of the water-receiver. The upper arm of the valve-lever h is inclined away from the wall of the water-receiver and provided with a weight which tends to keep the valve 9 closed. An inclined plane 2' projects downward from the top of the chamber A in the path of the lever 72 so that when the float carries the said lever up into engagement with the inclined plane the valve 9* will be opened. The vacuum-valve and air-valve in this case are operated by the float in practically the same manner as described in connection with Fig. 1, and friction-springs a", attached to the wall of the chamber A to press the valve-rods and hold them in either of the two positions in which they may be placed.

In the form of my improved water-elevator shown in Figs. 1 and 2 the operation is as follows: The pipe G being connected with a vacuum-pump, the air is exhausted from the entire series of chambers A, and the pipe H of the lower chamber of the series being inserted in the body of water at the bottom of the shaft or well air-pressure causes the wa ter to rise in the pipe H and enter the compartment B of the first chamber A of the series, and the valve m being closed and the valve 7' being open, and there beingfree communication through the slot 6 between the compartments 0 and D, the water in the con1- partment B lifts the valve cl and flows into the compartment 0, and when the said compartment is' filled with water it overflows through the slot e'into the compartment'D. As the lower part of the chamber Afills with water the float F rises, and coming into contact with the stem j of. the valve glifts the valve 9 and allows the water contained by the compartment to quickly flow into the-compartment A, thus causing the float F to rise quickly. The arm 6, attached to the valveoperating rod d, being longer than the arm 6 ofither'od d thesaid arm e is engaged by the float F before the arm 6 and the vacuumvalve is closed against its seat, in which position it is held by the weight on the valvearm 8 and by the float. The apertures of the ears attached to the float being elongated and the water] cohtin'uingtb flow into the lower part of the chamber A from the compartment 0, the free side. of the float continues to rise,

thus tipping it slightly and bringing it into engagement with the arm e? of the rod ri and the said rod by the engagement of the lugs f with the finger p of the valve-arm Zopens the valve m, thus establishing communication between the interior of the compartment D and the external air. At this point in the operation the valve 01 closes and water continues to flow into the compartment B, the communication between this compartment and the vacuum pump not having been broken. The pipe H is connected with the bottom of the chamber A and communicates with the top of the compartment 13 of the next chamber above, and the air having been exhausted from the next chamber above the water contained in the lower part of the lower chamber is forced by atmospheric pressure upwardly through the pipe H and delivered to the compartment B of the second chamber in the manner already described in connection with the first, when the same series of operations occurs in the second chamber, and as soon as that chamber is filled the vacuumvalve 1" of that chamber is closed and the water contained by the second chamber is elevated to the third. In the first or lower chamber as the water is discharged the float F descends, and when it reaches its lowest point it first strikes the angled end of the rod d forcing the said rod downwardly, and by virtue of its engagement with the lever of the valve m closes the said valve and thus shuts off communication with the external air, and the opposite side of the float descends, openingthe vacuum-valve, when pressure is equalized in the various chambers, and water again overflows from the compartment B into the compartment 0 and the operation already described repeats itself.

The operation of the modified form shown in Figs. 3 and 4: is as follows: The upper end of the pipe H is connected with a pump and the air is exhausted from all of the chambers A, the valve m being closed. The lower end of the pipe H being immersed in water, water is forced by atmospheric pressure through the pipe H and delivered to the compartment 0. When this compartment is filled,- the water "overflows" through the slot 6 into the compartment D and the float F" rises, being guided by thetube a Asthefloat nears the upper limit of its -n1ovement it strikesthe stem j of the valve ghopeningthe said valve and allowingthe water to'flow from thecomp'artment O to the compartment D, thus suddenly adding to the volume of the water in the compartment Dycausing the float F to rise farther and open the valvemfby its engagement with the lug e The air entering "through the tube a forces the water upwardly "through the pipe H into the'next chamber above, and when the next chamber above is filled the float opens the. air-valve of that chamber andwater iscarried from that chamber. to the thi'rd,and soon throughout-the series. As the water is-discharged from the lower' chamber A the float 'Fdescends,and

engaging the angled'lower end of the rod d "closes the valve'm, when the air is a-gai nex- 'hausted from the *chamberA and *what has I already been'described' is repeated.

It will be noticed tha tboth air and water ascend through the pipe 11'.

It will also" be noticed that the weighted lever 13 'holdsthe valve m in eitherof the two positions in which it is placed until the valve-rod is again. moved by the float.

In the modification shown in Figs. 5 and 6 the operation is like that described in connection with Fig. 3, except as regards the forked pipe H. In this case the branch k of the pipe H is closed by the valve it when the float F is raised, and the valve 11 is then opened, so that most of the water passes through the branch 71: but when the float descends far enough to close the valve 01 and open the valve n the water remaining in the pipe H is preserved in a solid column by the ball 0 which nearly fills the pipe and thus permits of carrying the entire column of water upwardly and discharging it into the next chamber above, and after its upward excur sion the ball 0" returns it to the lowest position by its own gravity. It will thus be seen that the branches k of the pipe H are alternately opened and closed as the float rises and falls.

In the modification shown in Fig. 7 the operation is substantially like that of the form shown in Fig. 3.

In the form shown in Fig. 9 the extra supply of water for causing the float to operate quickly during the latter part of its upward travel is carried by the float itself,and when it is discharged into the chamber it not only augments the supply of water which forces the float upwardly, but the discharge of the water lightens the float and increases itsbuoyant power.

It will be seen that in the modifications shown in Figs. 3 to 7, inclusive, the water which enters the chambers D and D will have to pass through the whole series and be discharged from the system before a vacuum can again be established in the lower member of the series and a flow be reestablished.

By inclosing the float-rods in tubes and employing the tubes as guides for the float the float is kept out of frictional contact with the rods, and positive action is insured.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a water-elevator, a chamber having a float-compartment, and a water-receiving compartment having an overflow discharging into the float-compartment, a valve-operatiu g float placed in the float-compartment, a floatoperated valve for controlling communication between the water-receiving compartment and the float-compartment, and air and vacuum valves for controlling the admission and escape of air, substantially as specified.

2. In a Water-elevator, a chamber having a floatcompartment and a water receiving compartment having an overflow discharging into the float-compartm cut, a valve-operating float placed in the float-compartment, a floatoperated valve for controlling communication between the Water-receiving compartment and the float-compartment, a water-suction pipe, a vacuum-pipe, and a water-reservoir in constant communication with the vacuumpipe, substantially as specified.

3. In a Water-elevator, a compartment chamber in which are provided a float-compartment, a Water-receiving compartment provided with an overflow discharging into the float-compartment, a water-reservoir compartment provided with a valved tube opening into the Water-receiving compartment, a valve for establishing communication between the iloat-compartment and Water-receiving compartment, vacuum and air valves, and a float and float-rods for operating the valves, substantially as specified.

4. In a water-elevator, the combination, with the air, vacuum and water valves having contact-stems of different lengths, of a float for striking the valve-stems one after the other and operating the valves in succession, whereby the water-valve is opened first, the vacuum-valve is closed, and the air-valve opened in their order, as described.
