This invention relates to pumps and more particularly has reference to pumps associated with a dam or bulkhead to cause water to flow from one side of the dam or bulkhead to the other side thereof.

An object of this invention is to provide a pump for moving water in a ditch to effect a supply for irrigation or a condition of drainage.

Another object of this invention is to provide a pump in a dam, bulkhead or similar means separating two parts of a body of water for effecting a flow from one part to the other.

A further object of this invention is to provide a pump mounted in a plate adapted to serve as a gate in a dam or bulkhead or as a stationary part of said dam or bulkhead.

Still another object of this invention is to provide a pump mounted in a plate adapted to serve as a gate in a dam or bulkhead or as a stationary part of said dam or bulkhead in which the plate is constructed so that it may be reversed to reverse the flow effected by the pump.

With these and other important objects in View, which may be incident to my improvements, the invention resides in the parts and combinations to be hereinafter set forth and claimed, with the understanding that the several necessary elements comprising my invention may be varied in construction, proportions and arrangement, without departing from the spirit and scope of the appended claims.

(Cl. 10B-104) Fig. 12 is a plan view similar to Fig. 8 in which the supporting plate is plane.

Fig. 13 is a horizontal sectional view of Fig. 1. The structure of the present invention is particularly adaptable for use in pumping water 5 from one level to a higher level in ditches and canals. As shown in Fig. 3, the invention may be incorporated in a dam or bulkhead I separating two reaches of a body of water 2 usually at different levels. For purposes of illustration, 10 the body of water 2 may be considered to be a ditch or canal, but it should be clearly understood that the invention is equally applicable to other bodies of water. In applying the present invention, the bulkhead is constructed with an 15 opening into which the pump unit of the present invention is inserted.

As more clearly shown in Figs. 1, 2 and 4, the pump unit comprises a frame formed of two spaced upright timbers 3 and 4 secured together 90 by upper and lower cross-members. Secured to the frame is a pump supporting plate 'I. In this form of the invention plate l, as shown in Fig. 4, is provided with an oval-shaped opening 8 in the center thereof and a slot-like open- 25 ing 9 extending upwardly to the top of said plate.

Positioned in opening 8 is an S-like fitting Ill, one end II of which opens on one side of plate 'I and the other end I2 of which opens on the other side of said plate. This itting I Il may be secured to plate 'I in the opening 8 in any desired manner, such as by welding, brazing, soldering or by bolts or rivets.

A tube I3 extends upwardly through the top of fitting I0 and is positioned in the slot 9 of plate l. 35 'I'he upper part of tube I3 is provided with anges I4, which are bolted or riveted to plate' 1. Of course, tube I3 may be welded or otherwise secured to plate 1.

Bearings I5 and I6 are mounted in the upper 40 and lower ends of tube I3 for rotatably supporting a shaft I'I. An impeller I8 is mounted on the lower end of shaft I'I and is rotated thereby. In this form of the invention the impeller is of the screw type and is constructed and rotated to cause the water to be drawn in through opening or port I I and discharged through opening or port I2. A ring I9 surrounds the periphery of impeller I8 and is mounted in fitting III.

As an alternative construction, ring I9 may 50 be secured in position in opening 8. In this instance, the lower portion of tting IIJ is formed of two parts, one secured to one side of plate 1 and the `other to the other side of the plate. Similarly, the upper portion y of fitting I0 is 55 Lili formed of two parts on opposite sides of plate l. Both the upper and lower parts of fitting l are secured to ring I9.

In both forms of construction, water-tight connections are effected between the parts and plate l.

The pump unit is positioned in the bulkhead or dam, as shown in Fig. 3 by driving the posts o-r timbers 3 and i into the bottom of the ditch or other body of water. In Figs. 1 and 2, the cross-member G is shown spaced from the bottom of the body of water, but in an actual installation the unit is driven down until the member S engages the bottom. If desired, however, a plate 'I' may be provided beneath cross-member 6 to close the space between member 6 and the bottom when member 6 is not driven to the bottoni.

For rotating the impeller i8, the shaft l1 is provided with a pulley 2! which is driven by a belt E! driven by a motor 22. Of course, it is obvious that the source of power, such as an electric motor, may drive shaft l1 directly or through suitable gearing.

To prevent the back flow of water from the high level side of the dam to the low level side thereof when the pump is not operating, a check valve in the form of a swinging gate is hinged at its upper end to the discharge port i2 of the pump housing iii. When the pump is stopped. the gate will close by gravity. and as there highei1 water pressure on the higher level of dam, pressure will tend to close the gate. Cif course, when the pump is again started, the discharge pressure of the pump will open the gate.

A slightly modified form of the invention is shown in Figs. 6 and '2. In these gures. the pump is mounted on a plate slidably supported in guides. Tn this instance, vertical posts 2Q and are sunk into the bottom of the body of water and are provided with guides 25 and 21 in which plate 1.8 slides. Plate which carries the pump. is intended to be driven down into the bottom. of the body of water, or a separate plate 28 is sunk into the ground.

It will be realized that by having the plate 28 mounted for vertical sliding movement, it will serve as a gate to permit the flow of water through the dam or bulkhead. The plate or gate 28 may be raised by any suitable means. For purposes of illustration, a block 29 is shown supported by a cross-beam 3i). Rope or cable 3i may be passed through the block and secured to the plate 2i? to raise the same. Of course, any type of hoisting mechanism can be used for this purpose.

In the form of construction shown. in Figs. 6 and .7, the pump is mounted on the plate in manner somewhat differently from that shown in the preceding figures. As shown, the plate is provided with a central opening, but there is no vertically extending slot.

Ring 32 is mounted in the opening in plate 23 in a horizontal position. The pump housing comprises an upper hood-like member 33 extending upwardly from the ring 32 on the intake side of the plate and secured to plate 23 about the upper portion of the opening A sec tion 7M extends downwardly from the sides of the ring to form an. intake port 35. Op. the opposite side of the plate, a curved plate 3.5 ex tends downwardly from ring 32 and is secured to plate about the lower portion of the opening to complete the intalte portion of the pump casing or housing. A collar-like member 3l extends upwardly from ring 32 on the opposite side of the plate from member 33 to cooperate with said member to complete the discharge portion of the pump casing or housing. The member 3l' forms the discharge port of the pump housing and is provided with a gravity closed gate 38 which acts as a check valve, as described in connection with Figs. 1 and 2.

A tube 39 provided with upper and lower bearings 4G and Qi extends downwardly into the pump housing and upwardly on one side of the plate 28. This tube is provided with a flange 62 which cooperates with the member 33 of the casing or housing, lTube 39 is secured to the plate 28 by flanges i2 and 43. A shaft fifi is mounted n the bearings 46 and fai and carries an impeller on the lower end thereof. On the upper end of shaft Mi is mounted a pulley Q6 by which the shaft is driven.

In Fig. 5, there is shown a centrifugal type of pump mounted on a plate 37 which may be supported as shown in either Fig. l or 6. This form of construction differs from those hereinbefore described in that the impeller is of the centrifugal type, rather than the screw type, and the pump housing or casing is constructed accordingly. As shown, the tube Gil, carrying the bearings 459 and 50 which support shaft 5i, is secured to plate 47 above the opening formed therein. The casing or housing in this form of construction comprises a semi-circular member 52 secured to plate l about the opening therein. On the opposite side of the plate there is mounted an outwardly flared discharge member :i

53, the mouth of which is provided with a gate 54 similar to those hereinbefore described. 'The members 52 and 53 cooperate to form a discharge chamber having an axial opening in the bottom thereof, to which is secured the inlet iitting 55.

An impeller 5G is mounted on the lower end of shaft 5l to rotate within the casing4 as shown. This impeller comprises upper and lower disclike elements 5l and 58, between which Lare positioned a series of annularly arranged curved varies 59. The lower element E8 has a central opening registeringr with the inlet opening in the bottom of the housing. When the casing or housing is flooded with water, rotation of the impeller will cause the vanes to centrifugally throw the wat'er into the casing surrounding the impeller and will effect a discharge through the opening controlled by gate 54. Of course, this action Will create a suction through fitting 55 and the water will be forced from one side of plate 4l to the other.

In Figs. 8-12, a further modification is shown. This form of construction dif-fers from that shown in Fig. 5 in that two inlet ports are pron vided in the pump casing or housing. As shown, the plate supports the tube lil which is secured thereto by flanges '62 or in any other manner. Tube 6l is provided with upper and lower bearings '63 and 64. in which the shaft 65 is rotatably mounted, As in the preceding forms. the shaft carries a pulley F56 at its upper end and an impeller at its lower end. In this instance, the impeller is formed of a disc 61 fixed to the shaft, which disc carries a series of annularly arranged curved varies SB extending in an axial direction on each side of the disc. Annular plates 89 and i are secured to the upper and lower edges of the varies to complete the cage-like impeller. At the center of plates 63 and l0, annular flanges 'Il yand 'l2 are provided which surround the openings for the intake of water.

The casing or housing comprises a semi-circular portion '3 surrounding the impeller on one side of plate Gil and a flared out discharge portion 14 on the other side of the plate. Curved sections 'l5 and lli extend upwardly and down- Wardly from the discharge section 'lll to close the opening in plate GEB and complete the pump casing or housing.

In operation, the casing and impeller cage are flooded with water; then, upon rotation of the impeller, water is thrown radially into the space surrounding the periphery of the impeller and forced out through the discharge port il. This action causes water to be drawn into the casingv through the intake ports l@ and iii. Of course, the discharge port il may be provided with a gate 80, as in the hereinbefore described forms.

In the forms of construction in which the impeller shaft supporting tube is mounted so that the axis of the shaft is spaced from the supporting plate, the plate is formed with offset anges. As shown in Fig. S, plate lil) is provided with offset guiding flanges Bl and 52, which lie in a plane passing through the axis of shaft S5. rlThis enables the plate E0 to be rotated through an angle of 180, so that the flow of water will be reversed without disturbing the position of the axis of shaft 65. In other Words, the position of shaft and pulley BB will be the same, regardless of the position of plate 6l).

The advantage of my particular pump is its simplicity, compactness, lov.7 manufacturing costs, ease of installation, accessibility for repairs, etc. Another advantage is that the plate supporting the pump may be rotated through an angle of 180, so that the pump will create a flow in the opposite direction. In operation, thewater is simply pushed through the bulkhead and the head against which it must pump is equal only to the difference in Water levels on the opposite sides of the bulkhead. If it is desired to permit a normal flow of the ditch in which it is mounted, the pump may be hoisted in its ways, opening up a clear passage.

Although my pump is shown only in a simple form, refinements are contemplated, such as a geared head with different speed ratios and a more satisfactory belt drive, or a direct driving connection to the prime mover may be provided instead of the vertical pulley shown. The impeller housing or casing may be split about a line through the impeller drive shaft, so that the rear or circular half of the housing may be removed and thus expose the impeller for removal.

While I have shown and described thepreferred embodiment of my invention, I wish it to be understood that I do not confine myself to the precise details herein set forth by way of illustration, as it is apparent that many changes and variations may be made therein by those skilled in the art, Without departing from the spirit of the invention or exceeding the scope of the appended claims.
