AUTOMATIC COMPRESSED-AIR WATER-ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 396,405, dated January 22, 1889.

Application tiled December 8, 1887. Serial No. 257,338. (No model.)

To @ZZ whom t may concern;

Be it known that. 1JOHN K. IJEEDY, a citizen of the United States, residing at Toms Brook, in the county of Shenandoah and State of 'Iirginia, have invented certain new and useful Improvements in Automatic Oompressed-Air lYater-Elevators, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in automatic compressed-air water-elevators, which improvements will be fully understood from the following description and claims, when taken in connection with the annexed drawings, in which- Figure l is an elevation, partly in section, showing my improved automatic compressedair water-elevator, the parts being in a state of rest and the gravitating bucket being in position to receive water. Fig. 2 is an enlarged sectional view oi;- the intermediate tripping-valve mechanism and its air-pipes, indicating by the aid of dotted lines a handlever which may be substituted for the working-beam and its toe, as represented in Fig. l.

Referring to the annexed drawings by letter, A designates a strong vessel,which I shall hereinafter denominate the air-storage vessel. This drum communicates, by means of a pipe, c., with a suitable air-forcing engine, adapted to compress air under great pressure into the said drum, which latter is provided with a gage, b, and a safety-valve, c. From the drum A leads otf a pipe, d, provided with a regulating and cut-oit' cock, a', which pipe leads into one end ot' a strong valveboX, B, and at, d is providedV with another regulating-cock, it' found necessary.

The valve-box B, into which the compressedair-supply pipe dy is tapped, has a chamber, b5, terminated by a cone valve-seat fora cone trap-valve, b3, which is provided with a spiderguide, b, working against the wall oi cham- 45 ber b, The valve b3 is somewhat less in diameter than the diameter ot the chamber b, and it is applied on the end of the reduced stem b2 of a cylindrical plunger, b', the outer end of which protrudes beyond the endoi 5o valve-box B, for a purpose presently explained. At cX is a vertical outlet-passage through the valve-box, and at h is a similar passage. The passage c communicates, by means of a pipe, O, with a submerged drum, D, and the passage b is an outlet for air when the plunger b is at the terminus of its outward stroke. (Indicated in Fig. 2.

The drum D may be located at any practical depth in a well, E, and it should be provided at its bottom with a suitable valve, fi, opening upwardly, for allowing water to iiow through the valve-aperture into the said drum, but to trap the water therein. Near the lower end of said drum D isa bell-mouth connected to an outlet-pipe, F,which extends upward out of the well, and is curved, as shown in Fig. l, and secured to the bracket-arm yn of a standard, H, and terminates in a discharge-nozzle, f, directed downward. This discharge-nozzle f is located in such relation to a bucket, G, that it discharges water therein.

The bucket G is pivotally secured to one limb of a working-beam, J, which has a V-edge fulcrumed at k on a standard, S. The bottom of the bucket G is provided with an outlet-pipe, g', having a regulating or cut-off valve, g2, and a seat, g3, which latter, when the bucket is at its highest point, is closed by a iiXed valve, g. The stem g3 of this valve g is vertically adjustable by means of nuts g4, impinging against the bracket-arm not the standard H, to which this valve-stem is secured. Directly beneath the outlet-pipe g of the bucket G is a water-receptacle, WV. (Shown clearly in Fig. lof the annexed drawings.

Th)e working' beam or lever J can be nicely or properly adjusted to an equipoise by means of weights w uf, hung from its extremities, and one limb of this beam is guided in a slot, t, in the standard H, while the opposite limb, J', is guided in the bifurcated upper part of a standard, K. This limb J is constructed with a trough, r, adapted to afford a track for a shifting ball, Z, which trough is turned up at its ends j '7",to prevent the said ball escaping from it at the` termini of its strokes.

I apply in the vertical-slot-of the standard K an adjustable rest or stop, s, upon which is supported the arm J of the vibrating beam J, when this beam is in the position shown in Fig. l. (In close relation to the fulcrum of IOO ein

the beam J and rigid therewith is an arm or toe, y", iihieh, when, the said beam. is in the position. indicated in Fig. I, will press the plunger b inward a sufficient distance to close the vent l and open the valve DH, as will more fully hereinafter appear.)

The operation of the elevator is as follows: The storage-vessel A having been charged with air under considerable pressure, the cocks a cl are opened more or less. Compressed air will now pass from the storagevessel through pipe l and press upon the water in the submerged drum D, tightly closing cheek-valve t' and forcing the water up th rou gh the pipe F and discharging it from the nozzle finto the vessel G on one arm of the beam J. IVhen the weighto't' water in vessel G preponderates over the ball Z, this vessel will descend, leaving the valve g and openingthe outlet passage through the discharge-pipe g, thus allowing' water to vflow from said vessel G into the tank XV. The rapidity of .liow from vessel G can be regulated by means of the cock g2. At the moment the vessel G starts to descend the pipe g will be opened, and simultaneously therewith the toe or arm will leave the en d of the plunger b, thereby allowing the pressure of air to close valve Ui against its seat. The air-pressure from the reservoir A will new be cut off from the submerged drum D in the well E and the vent l) opened. This operation will instantly relieve the drum D and allow water to flow into it through its valve-opening. As the arm of beam J, on which is hung the bucket G, descends, the ball Zwill roll toward the fulcrnm of this beam and insure a steadincss to the working thereof. \Vhen the water has run out of the bucket G, the left-hand arm of beam J will preponderate and the bucket will rise, the several parts again assuming the positions shown in Fig. l. The valve b3 will now be open, the vent b closed by plungcrb, the outlet-pipe of bucket G closed by the stationary valve g, and the valve i in the submerged drum closed. Communication is established between the storage-vessel A and drum D and the water in it elevated by the compressed air and discharged into the bucket G, which, when it is filled, will again descend.

It will thus be observed that the operation of my water-elevator is strictly automatic as l long as the storage-vessel A is kept charged i with air. It' itis desired to control themovements of the apparatus by hand, this can be done by the employment of a hand-lever, I., as indicated in Fie'. 2 in dotted lines, by means otl which the plunger l1 and its valve can be operated.

Ilaving thus fully described mylinvention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination, with the storage-vessel, the submerged drum provided with a valve opening upward, a valve-box provided with a connected plunger and valve, and an air-vent, of pipes cormeeting the vessel A, the drum D, and valve-box 1E, a vibrating beam, J, provided with a toe, adapted to act on plunger b', a bucket hung from one armv of said beam and provided with an outlet-pipe, a stationary valve for this outlet-pipe, and a pipe leading' from the drum l) and arranged to discharge water into said bucket, all substantially as described.

2. The combin ation, with a pivoted workin gbeam, J, and a bucket, G, pivotcd to this beam and provided with an outlet and a valve-seat in its bottom, of a stationary adjustable valve adapted to close upon the valve-seat in the bottom oi' the said bucket, a support for the valve, a support for the beam J, a supply-pipe, F, emptying into said bucket G, and means for elevating the water, substantially as described.

3. The combination, with a pivoted weighted beam, J', provided with a toe, g5, a bucket, G, pivoted to the said beam, and a rolling counterbalancing-weight upon said beam, of a stationary valve, g, adapted to close upon a valveseat in the bucket G, a valve-box, B, a reciprocating valve in said box, this valve being opened by the toe g5 on the beam J, air-pipes (l e, a submerged drum, D, provided with an inwardly opening valve, and a watersupply pipe, F, leading from the drum D to the said pivoted bucket G, all arranged as and for the purpose herein stated.

In testimony whereof I affix my signature in presence of two witnesses.
