HYDRAULIC DEVICE Filed Aug. 24. 1949 2 SHEETS-SHEET 2 INVENTOR. 1am km Patented Jan. 29, 1952 HYDRAULIC DEVICE Nicolaus Habsch, Wuppertal-Vohwinkel, Germany Application August 24, 1949, Serial No. 112,160 In Belgium September 18, 1948 4 Claims. (Cl. 10355) This invention relates to a hydraulic device which achieves a very high pressure though a low drop 01 a river only is available, and particularly to a hydraulic device which is adapted by example for locations where a creek or river in a valley is to be used for feeding water to higher locations or for driving a turbine.

Thus it is one object of the present invention to provide a hydraulic device, the operation of which does not interfere with the water rights of neighbors or land owners on the same river, which is brought about by not using the flowing Water, which operates the device, as working water. This object is achieved by using ground water, which may be found in each valley and, thereby, also making possible the operation of several such devices in series from the same creek or river.

It is another object of the present invention to provide a hydraulic device which comp-rises a balance beam which is pivotally supported and each arm of which carries a water container which is positioned below a water outlet being equipped with a valve controlled by the movement of the balance beam.

It is another object of the present invention to provide a reciprocating balance beam to operate a pump which is fed by example from a well.

It is still another object of the present invention to provide a reciprocating balance beam for operating a pump, each arm of which beam carries a water container, and to provide one single control mechanism for simultaneously feeding the raised water container and discharging the lowered water container.

It is yet another object of the present invention to provide a hydraulic device with a reciprocating balance beam which interrupts the pumping action at the moment when the control mechanism for reversal of movement starts its operation.

It is a further object of the present invention to provide, in a hydraulic device with a reciprocating balance beam, each arm of which carries a water container, means for extending the open period of the valves for feeding and discharging said containers upon accidental or intended high pressure of the pump.

With these and other objects in view which will become apparent from the following detailed description, the present invention will be clearly understood in connection with the accompanying drawings in which,

Figure 1 shows a front elevation of one embodiment of the hydraulic device;

Fig. 2 is a front elevation, shown at enlarged scale, of the locking mechanism and in pointdotted lines the over-weight position; and

Fig. 3 is a section along the lines 3--3 of Fig. 1.

Referring now to the drawings, the hydraulic device comprises a balance beam 3 which is adjustable as to its length and which is supported by a pivot I mounted on a frame 2. Water containers 4 and 5 hang in swinging manner from each end of the balance beam 3. Each one of said containers is equipped with a discharge valve 6. A feed outlet 1 and 8, respectively, leads to the water containers 4. and 5, respec tively, depending upon the position of the balance beam 3, which feed outlets are equipped with valves 9 and extend from a feed pipe 10. Each one of the valves 9 is controlled by means of releasing rodsv ll, against which pushing rods #2 abut.

A swinging arm [4 is provided on each one of the two arms of the balance beam 3, which arm l4 carries a weight l3. A spring catch l5 retains the swinging arm. I4 when disposed at an acute angle to the vertical direction.

The spring catch I5 is linked to a check arm 18, which is controlled by a spring 11, by means of an angle lever IS. The hook-shaped end 20 of a latch 2| extending from a bolt 22 looks the extension IQ of the check arm l8. The nose 23 of the bolt 22 rests on a pawl 24, which is disposed on the arm 25 of a compensation weight 26 (see Fig. 2). The arm 25 together with the weight 26 is mounted in the frame 2 on the pivot 21. and slides in a curved guide 281. The pawl 24 is equipped with a compensation weight 30 opposite its tooth 29. The arms 3| of the pawl 24 are covered by a counter support 32. The bolt 22 is connected to one end of a draw spring 22, the other end of which is secured to a bracket 45 of the balance beam 3. The bracket 45 carries also the spring I! for the check arm IS. A lever 34 is secured to the supporting bolt 33 for the swinging arm l4, which lever 34 enters a slot 35 of the pushing rod I2 by means of a pin. One arm of an angle lever 38 slides in a slot 31 of an angle lever 36 which is also pivoted on the supporting bolt 33. The other arm of the angle lever 38 is disposed between two extensions 39 of a sliding rod 40 which slides along the balance wheel 3. The sliding rod 40 has at its ends cam members 46 which contact double levers 41, the latterbeing under pressure of springs (not shown),-which double levers 41 are pivotally secured to frame posts 4!. The nose-shaped ends 48 of the double levers 41 abut against the arms 33 of the discharge valves 6,

are equipped with valves 54. Tubes 55 branch off the pump cylinders 52, which tubes 55 lead to a chamber 56. The tubes 55 are equipped with reduction cocks 51. The piston rods 50 have links 58, against which abutting members 59 of the balance beam 3 press, just before the end angle levers are connected with sliding rails 66,,

to which the curved guides 28 for the weights 26 are secured.

Counterweights 61 control the piston rod 53 by means of bars 68 which are secured to the frame A bar rests on an extension 69 of the piston rod 63, which bar 19 leads to a valve H of an over pressure pipe 12, which branches off the water feed pipe 13'. v The present hydraulic device operates in'the following manner:

In the position'of the balance beam 3 shown in Fig. 1 the water container 4 is filled from the feeding tube I!) through the now open valve 9, while water which may be found in the lowered water container 5 is discharged. When the container 4 is completely filled, it has an overweight over the weight 26 and the latter is raised on its pivot 21, as indicated in point-dotted lines in Fig. 2. By this movement the pawl 24 frees the tooth 21 of the bolt' 22. The balance beam 3 is lowered on the right side (Fig. 1) while its left side is raised. At the same time the pushing rod 12 is lowered, thereby closing the valve 9. Upon lifting the empty water container 5, its discharge valve 6 will also close.

The pump with its pistons 5! is operated by the movement of the balance beam 3. The water passing through the suction pipes 53 is fed into the chamber 56 and pressed into the feed tube 13.

A short time before the container reaches the lowest level, the abutting member 59 exerts pressure towards the link 58 of the piston rod 50. The latter collapses partly and the corresponding piston 51 remains at its place. The thus freed forces bring about, upon further lowering of the balance'beam 3, first a raise of the weight [3 by means of the inclined plane 42 and then the lifting of the'latch 2| from the extension l9 of the check arm l8 (see left side of Fig. 1). The empty lifted water container 5 reached in the meantime the position below the feed outlet 8. When the water container 5 performs the lifting movement, the coordinated bolt 22 contacts thepawl 24. The bolt 22 is, thereby, turned andthe latch 2i rests behind the extension [9 of the check member l8, so that upon return movement of the bolt 22 the weight I3 is freed over the latch 2 l, the check member I8, the angle lever [B and the spring catch I5. The feeding valve 9 is, thereby, opened by means of the pushing rod l2. Upon turning of, the weight the an,-

gular lever 38 is turned also. The extensions 39 of the sliding rod 40 bring about the sliding of the latter. One of the cam members 46 abuts against the double lever 41 and opens the discharge valve 6 in the lowered water container 4 by means of the arm 49.

In case the chamber 56 receives a very high pressure due to closing the'feeding tube 13, the piston 62 is raised. At the same time the receiver 64 which rests on the piston rod 63 is lifted. The angular levers are moved sidewards and simultaneously move the sliding rail 66 and the balancing weight 26, so that an overweight is reached only with a' greater amount of Water. The valve H for the over-pressure pipe 12 is then opened by means of the extension 69 and the bar 18 due to the lifting of the piston rod 63.

While I have disclosed one embodiment of the present invention, it is to be understood that this embodiment is given by example only and not in a limiting sense, the scope being determined by the objects and the claims.
