APPARATUS FOR CLEANING CATCH BASINS AND THE LIKE.

Application filed June 19,

T all whom it may concern:

Be it known that I, GEORGE WV. OTTERSON,

a citizen of the United States, and resident of Seattle, in the county of King and State of Washington, have invented a new and useful Apparatus for Cleaning Catch Basins and the like, of which the following is a specification.

The invention relates to traveling apparatus for cleaning catch-basins and the like, such as that disclosed in my Reissue Patent No. 14,234, Dec. 19, 1916. The object of the present invention is to provide a simplified form of the vehicle tank-body set- 16 tling-bed forming a part of such apparatus.

Previously the baffle partitions were disposed transversely of the tiltable reardumping tank and were hung swingingly so that the separated solids could pass out beneath them. In the present instance the battles are placed longitudinally so as to form lengthwise settling chambers from which the material can escape in dumping without movement of the partitions; at the same time the organization is such that a circuitous flow is compelled from the inlet from the discharge line to the outlet to the pump which operates the ejector.

In the drawings forming a part hereof:

Fig. 1 is a side elevation of an apparatus embodying the invention, the settling-bed 'bein shown partly in side elevation and part y in section, and broken lines being used to show it partly tilted; and

Fig. 2 is a plan view.

The motor-vehicle 1 has a rectangular tank-body 2, its interior open to the pressure of the atmosphere, a pump 3 adapted to be driven from the engine of the vehicle by connections, not shown, and a hydraulic ejector 4 connected with the outlet of the pump and adapted to draw in and raise the contents of the catch-basins and cause their delivery into the settling-bed. The ejector 4 is adapted to be lowered into and raised from the basins, and has a suitable flexible pressure line 5 forming the connection between the outlet of the pump and the ejector-jet nozzle (not shown), and a flexible or telescopic discharge line 6 terminating in a suitable nozzle 7 projecting over the top of the settling-bed. An inlet line to thenpump is marked 8, the same load ing from a clear-water outlet 9 at one of 1919. Serial No. 305,239.

the lower forward corner regionsof the settl ng-bed.' A separable, automatically maklng and breaklng connection 10 between said outlet and the inlet end of the line 8 I is provided as disclosed in prior applications. The nozzle 7 of the discharge line is adapted to deliver the mixed stream of water and solids into the other forward cor-v ner region of the tank. ratus, with the tank in normal position, the ejector let down into a basin and the pump in operation, water is withdrawn from the settling-bed, wherein a supply is kept while the machine is upon its rounds, forced by the pump downward to the ejector, where the ejector jet is created, drawing in the contents of the basin through the intake 11 and forcing them upward to the settling bed on the vehicle, where the liquid is separated from the solids and continuously used. to supply the pump and jet. When the cleaning is completed, excess water is run back into the basin through a line 12.

The tank body is pivoted toward the rear upon the vehicle frame, as indicated at 13, and suitable hoisting means 14 is provided for raising its forward end in order to discharge the accumulated material at the back. A tight tail-gate 15 hinged at the top is untastened and swings rearward in this operation.

The interior of the tank contains a plurality of vertical baffles 16, 16 16 interrupting the flow of the water from the inlet from the discharge line to the clear-water outlet 9, causing it to pass in a circuitous manner so that the two regions are remote in point of flow. The number of these partitions may be varied, but it is characteristic of the present improvements that they extend longitudinally of the settling-bed, that is to say, fore and aft of the vehicle, and are or may be fixed. Flow openings 17, 17 17 are formed in their upper parts, alternately at front and rear, the baffle 16 nearest the inlet from the discharge line having its opening at the rear, and the open- In such an. appa ing in the last partition being likewise at the outward and consequently their solids pass out freely when the tank is tilted for dumping.

What I claim as new is:

1. In traveling apparatus for cleaning catch-basins and the like, a settling-bed comprising a vehicle tank-body tiltahle for rear dumping and having longitudinal battles forming lengthwise settling-chan'ihers.

2. In traveling apparatus for cleaning catch-basins and the like, a settling-bed comprising a reardumping vehicle tank-body divided into lengthwise communicating settling-chambers, with flow openings alternately at front and rear of the battles.

3. A settling bed comprising a tank-body tiltahly mounted on a vehicle for rear clumping and having a tight tail-gate, and equipped with longitudinal partition means provided with flow openings and dividing reassess the interior into lengthwise unobstructed settling chambers whereby the solids are retained and are freely discharged through the tail-gate opening when the settling-bed is tilted on its support. I

4. A traveling apparatus for cleaning catch-basins and the like, comprising a vehicle, a tiltalole rear-dumplng tank-body thereon, a pump having a clear-water inlet connection from the tank, a hydraulic ejector connected with the outlet of the pump and a discharge line for delivering back into the tank, characterized by longitudinal bafiies in the tank forming a series of lengthwise compartments with circuitous communication, the outlet to the pump and the inlet from the discharge line being in laterally remote compartments.
