so construct theguard'that it will prevent fish from entering the irrigating system,

but at the same time not interfere with water entering the inlet canal. 7

Another object of the invention is toso construct the guard that it will prevent drift from collecting at the mouth of the canal.

other object of the invention is to'so construct the-guard that it may be put in place no matter whether the two sides of the canal terminate in alinement or out of alinement.

Another object of the invention is to so guard that its frame may be formed from a single sheet of material.

This invention is illustrated in the ac companying drawings wherein Figure 1 is a plan view showing the guard in place with the sides of the canal terminating in alinement; Fig. 2 is a view similar to Fig. 1 showing the guard in place with the two sides ofthe canal terminating out of alinement. Fig. 3 is a fragmentary plan view of the guard; Fig. 4 is a view in elevation looking at the outer face of the guard; Fig. 5 is a view in elevation looking at the inner face of the guard.

Referring to the drawings it will be seen that this device is to be placed at the outer end of the inlet canal 10 which leads from the river 11 from which the water for the irrigating system is drawn. The ends of the guard are secured to the post 12 and since the guard is to a certain extent flexible, it may be readily connected with the post no matter whether these posts are in alinement as shown in Fig. 1 or out of alinement as shown in Fig. 2.

The guard is formed from an elongated strip of material 13 which is preferably metal or some other similar material. This strip is to be of such width that it will extend to the bottom of the inlet canal, and also if desired extend as far above the level of the water as the person constructing the Application filed October 31, 1913.

canalmay wish. This strip 13 has tongues 14 struck therefrom and is bent transversely along the lines of the side edges of the openings formed by these tongues14 so that the tongues will extend outwardly at an acute angle to the openings as shown in Fig. -3.

hese tongues 14 will extend out into the river 11 with their free edges extending down stream so that logs and other drift fioatingdown the river will be guided away and thus prevented from lodging against the guard. It is also to be noted that by having the strip crimped, as shown, the guard will be resilient and will thus be able to stand a blow received when a large log strikes the guard. It will therefore have a spring action to prevent its being broken or drawn loose from the post 12. It will also be noted that this construction will permit the strip to be stretched strip is cut a little too narrow and that it may also be compressed in case it is cut a little too long for the width of the canal.

The prime object of this construction is to cause the tongues 14 to guard. A strip of wire mesh 15 is placed against the inner face of the strip 13 and is secured in place by wires 16 which extend along the inner face of the wire and are ings formed by the tongues 14.

The manner of using this guard will be very clearly understood from an inspection of Figs. 1 and 2. The guard which may be made in long strips and wound upon suitable reels is cut the proper length and these pieces which are cut from the roll are then secured at their ends to the posts 12 by any suitable means such as nails or the like. As alreadv explained, the strip must be cut full length so that when in place the guard will be bowed outwardly as shown in Figs. 1 and 2 and extend into the river 11, thus causing the drift to be guided out into the center of the river where the current is strongest. A

guard constructed in this manner Will not be liable to be quickly destroyed or the Wire dragged loose the inner face of the strip and therefore can not be caught by the drift. The spring action already explained Will prevent large logs from striking the guard and tearing it loose from the post.

What is claimed is:

1. A ditch guardcomprising a strip of material having tongues struck therefrom and being crimpcd transversely in alinemcnt with the openings formed by said tongues to cause the tongues to extend outwardly at an angle to said openings, and screening secured to the inner face of said strip and extending across said openings.

2. A ditch guard formed from a strip of resilient material having tongues struck Copies of this patent may be obtained for 'five cents each, by addressing the since the Wire is placed'upon an angle to the openings therefrom and being crimped transversely to cause said tongues to extend outwardly at formed by said tongues.

3. A ditch guard formed from astrip of material crimped transversely to provide alternate faces extending substantially parallel, one set of parallel faces being provided with openings, and strips extending out- Wardly from the second set of parallel faces partially across the openings formed in the first mentioned set of parallel faces.
