WALTER C. CLARK, OF CANBY, OREGON.

AUTOMATIC PUMP.

Specification of Letters Patent.

Patented Nov. a,- 1913.

Application filed September 3, 1912. Serial No. 718,351.

To all whom it may concern Be it known that I, WVALTER C. CLARK, citizen of Great Britain, residing at Canby, in the county of Olackamas and State of Oregon, have invented certain new and useful Improvements in Automatic Pumps, of which the following is a specification.

My invention relates to pumping devices and particularly to devices of this character operated by the flow of water.

The main object of the invention is the provision of a pumping device or pumping motor for use where the small quantity of water at command or the limited fall or head of water precludes the employmentof a hydraulic ram.

A further object of the invention is the provision of a pumping motor or pump actuating device which will work with a very small water supply and is effective with a very low head.

A further object is to provide in a construction of this character, an extremely simple mechanism which is capable of being operated either with waste water or with a certain quantity of the water designed to be acted upon by the pump.

A further object is the provision ofa structure of this character in which means is used for regulating the supply of water to the motor in proportion to the work performed.

A further object is to provide a bucket of peculiar construction adapted to be tipped upon its descent and thereby discharge the water contained within the bucket, an object being in this connection to provide a construction which will quickly and completely empty the bucket and thereby greatly add to the efficiency of the machine.

My invention is illustrated in the accompanying drawings wherein:

Figure 1 is a side elevation of an apparatus constructed in accordance with my invention. Fig. 2 is a plan view thereof. Fig. 3 is a side elevation of a modified form of the apparatus shown in Fig. 1. Fig. at is a detail view of one of the buckets. Fig. 5 is a detail sectional view of the casing or box into which the inlet pipe discharges.

Referring to these drawings, 2 designates a framework of any suitable construction shown as embodying uprights 3, a base beam or beams 4, transverse beams 5 and 6 and a vertical beam 7. Mounted upon the vertical beam 7 in anysuitable manner is a walking beam or lever 8 carrying at one end a susstable equilibrium between the links 10. The V bucket is triangular in form; and is pivoted below its center of gravity- One side of the bucket is formed with a stop lug l3 disposed to one side of the vertical center of the bucket and adapted to contact with one of the links 10 and limit the movement of the bucket to a horizontal position until tipped. For the purpose of tipping the bucket when it has descended to its lowest point, I provide an upwardly projecting standard 11 and a chain 14 which extends to the upper margin of the-bucket.

Mounted upon the base 4 in any suitable manner is a pump 15 of any desired construction but preferably, an open top pump with inverted cup leathers. The type of pump shown is a single acting pump and I do not wish to be limited to the particular form of pump as this specific form is not any part of my present invention. The pump is connected to a supply pipe 16 and extending from the pump is a discharge pipe 17. The supply pipe 16 is shown as extending to and receiving water from a pipe 18 which is relatively larger in diameter than the pipe 16. This pipe 18 extends beyond the junction 19 and extends into a box or casing 20 which has about the same capacity as the bucket 12. This box or casing has a downwardly extending discharge nozzle 21, the passage through which, is controlled by means of a flap valve 22 which may be made in any suitable manner. The piston of the pump is designated 23 and is connected to the walking beam 8 intermediate of thepivotal center of the walking beam and the con-' nection of the beam to the weight 9. For the purpose of operating the valve 22, 1 provide a pivoted rod 2 1 pivotally supported from the beam 6 and connected by achain 25 to the cut-off valve and by a chain 26 at its other end to the walking beam 8 intermediate the point of attachment of the rod 23 and the pivotal point of the walking beam. The operation of this form of the invention will be obvious. In its initial position, the bucket 12 is disposed as shown in dotted lines immediately below the nozzle 21. Water from the supply pipe 18 is disthe standard 13, the bucket will tip discharging water. WVith the peculiar form of bucket shown, the bucket willtip very quickly once it has been overloalanced and all of the water will bedischarged from the bucket. Of course the bucket is prevented from tipping too far by reason of the chain 14 which acts thus both to initially tip the bucket from its overturned position to its horizontal 'or'receiving position, and to tip-the bucket from its horizontal or receiving position to its discharging position and to limit its rotative movement; With the bucket in the posit-ion as shown by dotted lines in Fig. 1, water will be admitted thereto until the bucket begins to move downward by reason of the weight of the water. I The weight of the contents of the bucket holding it in a horizontal position untilthe bucket has moved to a position where the chainl i becomes taut. WVhen this occurs, the chain exerts sufl'iclent hfting force'upon the rear slde of i the bucket to impart to the bucket a slight tipping movement, whereupon the bucket,

since it is mounted in unstable equilibrium, will completely discharge its contents. As

soon as the bucket is filled and commences to lower, the cut-off valve will be operated to cut ofl the supply of water flowing to the bucket, but as soon as water has been discharged and the bucket end of the beam 8 has nearly reached its maximum height, the

a chain 26 will be drawn taut and the lever 24 operated to shift the cut-off valve to again permit theflow of water to the bucket.

In the construction shown in Fig. 1, the weight 9 is shown aspositively operating the pump while the bucket is used to counterbalance the weight 9. It will be obvious however, that the pump might be connected to the beam 8 between the pivotal center of the beam and the links 10, thus providing for an operation of the pump in conjunction with the descent of the bucket instead of in conjunction with the descent of the weight.

In Fig. 3 I showanother form of my invention. In this illustration I provide two pumps acting alternately and also provide twobuckets, one when'filled counterweighting the other empty bucket. In this figure, 27 designates a walking beam having links 28 at opposite ends. Pivotally mounted between these links are the buckets 29 constructed in precisely the same manner as heretofore described. There are two pumps 30 used, each connectedto a supply pipe 31 the pumps are connected by piston rods 33 to the walking beam 27, one on each side of the pivotal axis of the walking beam so that when the walking beam is oscillated, one of the pistons will be depressed and the other. raised. A supply pipe Set is provided with two nozzles 35, each'nozzle being disposed above the corresponding bucket 29. A barrel 36 extends upward from each nozzle and disposed in each barrel is a cut-ofi valve such as previously described.

Mounted upon the superstructure or framework are the rods or levers 38, each pivoted at its middle and each connected at its outerend by means of a chain 89 to the corresponding cut-off valve. The inner ends of the levers 38'o-verlap each other and the levers are connected at their inner ends, each by means of a chain L0 to the walking beam, one on each side of the, axis of the beam. Each bucket is connected at its inner end by means of a chain 4:1- to any suitable support or standard, in this case the upper end of the pump barrel 30. The operation of this form of my invention is practically the same as that heretofore described. As one bucket and to a discharge pipe 32. The pistons of it fills, it descends, raising the other bucket into position to be filled. When the descending bucket has reached its lowest position, it is tipped by means of the chain 41 a and discharges its contents. Meanwhile, the

other bucket is filling and as soon as filled; raises the first named bucket to its original L 5 position. This causes an oscillation of the walking beam 27 and an alternate actuation of the piston rods of the pumps.

it will be obvious that my construction is very simple, easily operated and that it may be run at very small expense.

While I have illustrated the buckets as being filled from the main supply pipeor pipes, it is to be understood that the buckets might be filled from supply pipes indepencb ent of the pipes supplying the pump or pumps, and that thus contaminated water might be used if desired as a means for op-y.

crating the pumping mechanism to elevate: a

pure water. It will be obvious also that the pumping mechanism is entirely automatic in its act-ion and that it requires no care or 1 attendance. The mechanism may be used for irrigating purposes orfor pumping wa-w ter into tanks or any situation where a pump is desired. a e

end of the inlet pipe, this box having a ca 1 pacity about the same as that of the bucket,

is to permit the discharge from the inlet pipe to be continuous, the boX being of the size stated in order that it may not overflow when the pump is operated at normal speed.

V The object of providing a boX'20 at the r connected to the piston, links suspended from one end of the beam, a bucket pivoted between said links in a position of unstable equilibrium, a stop on the bucket limiting the rotation of the bucket in one direction, a flexible connection fixedly attached at a point to one side of the path of movement of the bucket and between the termini of said path, the upper end of the flexible connection being attached to the side of the bucket opposite the stop, means for counterweighting the other end of the beam to cause the bucket end of the beam to lift when the contents of the bucket has been discharged, and means for discharging liquid into the bucket, said flexible connection when the bucket has reached the lowest terminus of its movement causing an initial tipping of the bucket to permit the discharge of its contents.

2. A pump motor including a supporting frame, a beam supported above the pump, buckets suspended in unstable equilibrium from opposite ends of the beam, discharge,

pipes discharging into each of the buckets, means for tipping the buckets to a horizontal receiving position when the buckets have reached their uppermost positions, said means causing the tilting of each bucket when it has reached its lowest position to discharge the contents thereof, cut-ofi' valves, one for each discharge pipe, and a pair of levers each pivoted intermediate its ends, each lever being connected at its outer end to one of the cut-off valves, the inner end of the lever being connected to the beam beyond the pivotal point thereof.

3. The combination with a pump, of a beam pivotally supported above the pump, a rod connecting the pump piston to the beam, a tipping bucket carried upon one end of the beam in unstable equilibrium, a counterweight operatively engaging the other end of the beam to lift the bucket end of the beam when the contents of the bucket is discharged, means for holding the bucket in a horizontal receiving position until the bucket has reached the lower terminus of its movement, said means causing the bucket to tip when the bucket has reached the lower terminus of its movement, a discharge pipe disposed above the bucket, the casing into which said pipe discharges having a dis charge opening, the casing having a capacity approximately equal to that of the bucket, a cut-off valve in the casing, a beam pivotally mounted above the first named beam and flexibly connected to the cut off valve, the other end of the last named beam being flexibly connected to the first named beam; 4. The combination with a pump, of a pivotally supported beam, a piston for the pump operatively connected to the beam, links pivoted to the end of the beam and depending therefrom, a bucket pivoted between said links in a position of unstable equilibrium, a stop projecting from the bucket and engaging with the links when the buckets are in a horizontal position, a chain support disposed in a plane between the path of movement of the bucket and the axis of thebeam, a flexible connection extending from said chain support to the inner end of the bucket and acting to hold the bucket in a horizontal position when the bucket is raised but causing said bucket to initially tip when the bucket is lowered, a counterweight operatively engaging the beam opposite the end of the bucket to lift the bucket end of the beam when the contents of the bucket is discharged, a discharge pipe disposed above the bucket, a casing into which said pipe discharges and having a discharge opening, said casing having a capacity approximately equal to that of the bucket, a cut-ofl valve in said casing, a beam pivotally mounted above the first named beam and flexibly connected at one end to the cut-off valve, the other end of the last named beam being flexibly connected to the first named beam.
