SAND-TRAP FOR CANALS.

Application led January 25, 1916.l

To all whom t may concern.'

Be it known that I, STEPHEN 7. OnnssY, a citizen of the United States, residing at Rocky Ford, in the county of Otero, State of Colorado, have invented a new and useful Sand-Trap for Canals; and l do hereby de clare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved sand trap, designed for construction in connection with irrigation ditches or canals and the like, to carry o sand deposits laterally.

One of the objects of the invention is the provision of a device of this nature, in which improved, efficient and practical features of construction are involved.

One of the features of the invention is the provision of a concrete or cement ditch or canal provided with transverse V-shaped sand deposit pockets, there being only one shown, in the bottoms of which laterally extending conduits are arranged, to carry off the sand and the like, there being gates in said pockets, through which the water in carrying off the sand through the conduits may seep or percolate, so that the sand and the like may be carried off without clogging.

In practical fields the details of construction may necessitate alterations, falling within the scope of what is claimed.

The invention comprises further features and combination of parts, as hereinafter set forth` shown in the drawings and claimed.

In the drawings: Figure 1 is a cross sectional view through an irrigation ditch or canal, illust-rating the improved sand trap or pocket as applied thereto. Fig. 2 is a cross sectional view through the sand trap or pocket on line 2-2 of Fig. 1. Fig. 3 is a plan view of the trap or pocket, showing the side walls of the irrigation ditch or canal.

Referring more especially to the drawings, 1 designates a canal or channel having a bottom 2 and the side walls 3 constructed of cement, concrete or the like, all of which canal or channel is sunken in an irrigation ditch or the like 4. The bottom 2 of the canal or channel is designed to be provided with a plurality of pockets, depressions or traps, only one of which is illustrated, and designated by the numeral 5. This pocket or trap extends transversely of the bottom of the channel or canal 2, and is V-shaped Specification of Letters Patent.

in cross section', as shown in Fig. 2, and provided with inclined end walls 6. E1nbedded in the cement or concrete bottom 2 and transversely thereof, but in parallelism with and below the bottom of the pocket or trap 5 is a conduit or pipe 7, which is closed at 8 at one end, and open at 9 at the opposite end, which open end may terminate at any suitable location, so as to carry off the sand and the like. This conduit 7 is provided with a plurality of upwardly eXtending short branch conduits 10, the upper open ends of which are flush with the bottom of the pocket or trap 5, in order to carry off the sand deposits and the like that may Hinged at 11 longitudinally to one of the side walls which are inclined as shown) of the pocket or trap is a grate 12 having an eye 13, and when closed or lowered is designed to engage the opposite inclined side wall of said pocket or trap as at 14:. The water in passing through the channel or canal carries the sand deposits and the like to the pockets or traps, where the sand and the like sieve or percolate through the openings 15 of the grate 12, and are carried off through the eX- tension pipes 10 and out through the conduit or pipe 7, thereby relieving the water in the channel or canal of the deposits of sand, sediment, and other foreign material. The member 12 may be in the Yform of the perforated plate or the like, just so long as it is provided with suitable openings. The eye 13 of the grate is designed to receive an implement whereby the grate may be raised and lowered, or agitated up and down upon its hinged connection, to cause the sand and the like to be washed off the upper surface of the grate.

The invention having been set forth, what is claimed as new and useful is:

In combination with a canal or channel constructed of cement or concrete comprising a bottom and side wall and sunken in an irrigation ditch, said canal or channel being provided with a transversely disposed sand deposit pocket or trap V-shaped in cross section, a conduit extending transversely below the channel or canal and in parallelism with and below the bottom of the pocket or trap, said conduit having upwardly extending sand outlet tubes, the upper openl ends of which are flush with the bottom of the pocket or trap, and a grate having hinge connections with one of the longitudinal inclinedA side Walls of the In testimony whereof I have signed my pocket or trap and arranged at a short inname to this specioation in the presence of 10 terval above the bottom of the pocket or two subscribing Witnesses.
