3 Uairns. till. 61-2) This invention relates to dredging and other methods for removing sand bars, deltas, and other accumulations of materials on river bottoms, inlets, and the like, and in particular an elongated structure having spaced converging baffles providing open cells extended across a river bed with a iluid injecting p-ump at one side or" the river for forcing duid through jets in openings at one of the ends of cells and with a suction pump on the opposite side of the river for drawing sand and other materials from the batiies or cells.

The purpose of this invention is to provide a sand remover that may readily be positioned in a sand accumulation at the bottom of a river and that is designed to be operated with jet action to remove the sand from the river bed and deposit the said on a bank at one side of the river.

Various types of dredging equipment have been provided for removing accumulations of material on river beds are the like and some of such equipment operates by suction or with jet action. However, for eicient operation of such equipment it has been found desirable to provide sand arresting pockets or cells with fluid discharged through nozzles under pressure for withdrawing sand from said cells and with suction means for receiving the sand and also conveying the sand to a remote point. With this thought in mind this invention contemplates an elongated open casing having a plurality of cells therein with iluid discharging nozzles positioned to create suction in the cells and with one pump for supplying fluid under pressure to the nozzles, and another pump for creating suction around the nozzles to facilitate Withdrawing sand from the cells.

The object of this invention is, therefore, to provide an elongated trough with transversely disposed partitions providing cells therein, with a pump at one end for discharging uid under pressure and with a jet action through ends of the cells and with a pump at the opposite end for drawing iiuid from the ends of the cells in which the jet action nozzles are positioned.

Another object of the invention is to provide a sand remover for river and bay bottoms in which the remover is designed to be assembled at the side of a river or bay and readily dropped into position with pumps connected to opposite ends thereof.

Another important object of the invention is to provide a river bottom accumulation remover which is designed to be used for other purposes.

A further object of the invention is to provide a river bottom sand accumulation remover having a pressure pump at one end and a suction pump at the opposite end in which the remover is of a simple and economical construction.

With these and other objects and advantages in view the invention embodies an elongated trough having spaced transversely disposed partitions therein dividing the trough into cells with a pressure header extended below the trough and having branch connections with discharge nozzles at ends thereof extended upwardly and into the cells and with a pressure pump connected to the header and a suction pump connected to the opposite end of the trough.

Other features and advantages of the invention will appear from the following description taken in connection with the drawings, wherein:

FIGURE 1 is a cross-section through a river bed showing a side-elevational view of the river bottom sand removing apparatus.

FIGURE 2 is a side-elevational view of the trough of the apparatus with part of the trough broken away and with the parts shown on an enlarged scale.

FIGURE 3yis a plan view of the trough showing the converging baffles in the sides of the cells.

FIGURE 4 is a longitudinal section through the trough taken on line 4 4 of FIGURE 3 showing the jet action nozzles positioned in throats of the cells and also showing a suction connection at the discharge end of the trough.

FIGURE 5 is a sectional plan taken online 5--5 of FIGURE 4 showing the converging walls or bafes of the cells and also showing the jet action nozzles in the small ends of the cells.

FIGURE 6 is a view looking upwardly toward they under side of the trough showing the uid pressure header with the branch connections of the nozzles positioned in the cells.

FIGURE 7 is a cross-section through the trough taken on line 7-7 of FIGURE 2.

Referring now to the drawings wherein like reference characters denote corresponding parts the improved river bottom accumulation remover of this invention includes an elongated trough having a base 10, a plurality of converging baffles havinginclined side walls 11 and 12 and slopingcover panels 13 mounted on the base and positioned withthroats 14 thereof aligned with a discharge nipple 15, pairs ofnozzles 16 and 17 positioned in the baflles, asupply header 18 having anipple 19 connected by ahose 20 through a pressure pump 21, the intake of which is connected by ahose 22 to a perforatedhead 23, and a suction pump 24 connected by ahose 25 to the discharge nipple 15 of the trough.

The length of the trough is such that the trough extends from one side of a river bed to the other and the number and size of the baffles is depended upon the size of the river.

As illustrated in FIGURES 6 and 7 theheader 18 is provided withbranch connections 26 and Z7 that extend upwardly through the base 1) and, as illustrated in FIGURES 4 and 5upper sections 28 of the branch connections extend toward the discharge end of the trough and the ends of thesections 28 are formed to provide thenozzles 16 and 17.

The trough is provided withside walls 29 and 30 from which theinclined side walls 11 and 12 of the baffles extend and the intake end of the trough may be provided with an end plate 31, as shown in FIGURE 4.

Also as shown in FIGURE 4, the trough may be formed in sections, withsections 32 of the base extended upwardly overlapping adjoining ends of the base portions of the sections.

With the units assembled to form a trough, as illustrated in FIGURE 1, theintake nipple 19 of the uidpressure supply header 18 is connected by thehose 20 to the pump 21 and the discharge nipple 15 is connected byhose 25 to the suction side of the pump 24 whereby the discharge of fluid under pressure through thenozzles 16 and 17 is accentuated by the fact that the nozzles are discharging into vacuum or suction whereby a iet action is produced so that sand sliding down thecover panels 13 drops into a suction area and is discharged through thehose 25 and pump 24. By this means, sand, as indicated by thenumeral 33, in FIGURE l is removed by jet action from a river bed and deposited on the bank at the side of a river bed. The discharge of the pump 24 may be provided with atube 34 by which the sand may be carried to a suitable point.

Although the trough is provided with pairs of jets or nozzles it will be understood that any suitable number of nozzles may be used and the bai-lle units may also be arranged in different designs.

It will be understood that modifications, within the scope of the appended claims, may be made in the design and arrangement of the parts without departing from the spirit of the invention.
