Because of the disposition of the pins IS in the Figure 5 is a plan view of the base of the gate. base I l, and of the disposition of the walls 16 and In the drawing, as best shown in Figure 1, a H, the members l2 are evidently well adapted to 55 resist displacement or overturning even though they are not cast integral with the base H.

The parts H and i2 may be cast and cured at some convenient point, and their shape and relatively low weight facilitate their transportation over fields, even in the spring when the soil is Wet and soft, to the service location.

Should the soil settle or become materially disturbed, due to unusual weather or flood conditions, it is obvious that the water gate of this invention is adapted to be readily disassembled and re-set.

Also, should a part become worn or damaged, that part may be readily and inexpensively replaced from stock parts Without renewing the whole structure.

It has been found that the combination of a fiat slab for a sill, and the outwardly and rearwardly diverging aprons produce a flow condition that does not encourage erosion of the soil about the gate.

Because of the ease with which the gate 99 may be disassembled, transported, and assembled in position, it is obvious that it lends itself peculiarly to the demand for the temporary placing of gates or dams, and to the shifting of gates as flow-conditions or flow requirements change in service.

The parts i2 are obviously interchangeable. When the side members are provided with apertures that extend the full height of the toe and Walls, or are provided with similar top and bottom apertures, they are reversible so that it is often possible to keep a gate in service by reversing a side member to bring the damaged portion to a position in which it does not materially affect flow control. Thus, should the lower portion of a toe or wall become damaged, the side member may be reversed to put the damaged portion above the water line.

It is also obvious that the pins in the slab may be arranged extending through the slab to provide anchorage in the soil, and to also make the slab reversible in service, as is indicated at 2| in Figure 3.

It will of course be understood that many changes may be made and numerous details of construction may be varied through a wide range without departing from the principles of this invention and it is therefore not the purpose to limit the patent granted hereon otherwise than necessitated by the scope of the appended claims.

What is claimed is:

1. A water gate for irrigation ditches, said water gate comprising a base slab, a pair of spaced side members removably seated on said slab, each of said side members comprising a pair of substantially similar and integrally formed and inwardly converging walls, said walls being provided with vertically extending apertures, and anchoring means entered in said apertures and secured to said base whereby said side members are secured against side movement and may be removed by vertically lifting them to clear said anchoring means.

2. A water gate for irrigation ditches, said water gate comprising a base, a pair of spaced side members removably seated on said base, a sealing material between said side members and said base, said side members each comprising a pair of substantially similar and integrally formed and inwardly converging side walls, said side walls being provided With vertically extending apertures, a sealing material in said apertures, a plurality of upstanding pins entered in said apertures and immersed in said sealing material in said apertures, said pins being secured at their lower ends to said base, said side members being removable by vertically lifting them clear of said pins.-

3. A water gate for irrigation ditches, said water gate comprising a base, a pair of similar and interchangeable and reversible side members removably seated on said base in opposed spaced relation to each other, said side members each comprising a pair of substantially similar and integrally formed and inwardly converging walls, and anchoring means secured to said base and slidably entered in said walls.

4:. A water gate for irrigation ditches, said water gate comprising a fiat base slab having anchoring pins projecting normally from the upper and lower faces of said slab, a pair of spaced and interchangeable and reversible side members removably seated on the upper face of said slab and housing the pins projecting from that face, said side members each comprising a pair of substantially similar and integrally formed and inwardly converging walls, the pins projecting from the upper face of the slab being vertically alined with the pins projecting from the lower face of the slab.
