TRAVELING AIPARATUS FOR CLEANING BASINS.

Application filed November '4, 1919, Serial No. 335,650. Renewed October 10, 1922. Serial No. 593,660.

To all whom it may concern:

Be it known that I, GEORGE W. O'ITERSON,

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

The invention comprises certain improve ments in traveling apparatus for cleaning sewer catch-basins and the like of the type disclosed in my Reissue Patent No. 14,234, dated December 19, 1916, and Patent 1,295,056 of Feb. 18, 1919. One of the objects is to provide an improved construction of the hydraulic ejector elevator, whereby the same is movable in and out at the side to cooperate with catch-basins at various distances from the roadway and is raisable to a compact traveling conditionwithout overhead projection or necessity for swinging the elevator lengthwise of the side. Another object is to provide means in the pressure line for adjusting the flexible hose section therein in such manner as to avoid kinking as the working elevator is lowered to follow the receding level of accumulations in the basin. Other improvements relate to the water outlet from the tiltable settling-bed tank, the connections to the intake side of the pump with which said outlet automatically breaks and makes connection when the tank is tilted and restored, and the means for returning water to the catch-basin at the conclusion of the operation, whereby simplicity and economy of construction with improved and more convenient operation are secured. .These and other objects and features of the invention will become apparent as the specification proceeds.

In the accompanying drawings, forming a part hereof:

Fig. 1 is a side elevation of a machine with the forward portion ofthe vehicle broken away and portions of the elevator broken away and in section, showing the apparatus lowered into a catch-basin, intermediate portions of the basin and the apparatus therein being broken away for economy of space;

Fig. 2 is a vertical sectional front elevation, taken just in front of the pump, with the drivers seat omitted for clearance;

Fig. 3 is a plan view;

at 4 to permit of rear dumping. 5 is a top,

hinged tail-gate held tight closed by releasable clamps 6, and adapted to swing rearward when the tank is dumped by raising its forward end by a suitable or known form of hoist 7 deriving its power from the driving engine of the vehicle.

top vhinge rods within the main part of the 1. interior of the tank, forming a series of compartments, the forward of which receives the discharge of liquid and solids elevated from the basins. A longitudinal stationary partition 11 extends parallel and adjacent one sidefrom the front of the tank to a point near the rear, forming a longitudinal gutter or relatively clear water space 12. The bafHes 8, 9 and 10 extend from this partition across to the opposite side of the tank, and the effeet is to constitute the tank a settling-bed wherein the water is caused to deposit its solids, finally entering the gutter 12 from the rear sufliciently free from material to be handled by the pump 13. The transverse baflles are adapted to swing rearward in the same manner as the tail-gate when dumping, in order to permit the deposits to slide out from beneath them, and are preferably ported to cause the water to flow in a circuitous course. The first bafile is, as shown, formed with a large passage opening 14 in one upper corner, and the next baifle with anopening 15 at the remote side, the latter opening being guarded at the front by a hood 16 forming a diving passageway which holds sticks and floating objects in this compartment. The rear bafile is preferably provided with sieve openings '17 in its upper and major portion for efiecting a final separation.

In the forward part of the gutter 12 in the bottom of the tank, there is an outlet opening 18, to the border of which is rigidly secured a downwardly projecting outlet fitting or neck 19, at the lower end of which A plurality of transverse baflles 8, 9 and 10 are hung upon 1 is a funnel mouth 20 containing a gasket 21,

forming one member af an automatic make and break sealing joint, after the manner disclosed inmy application Serial No. 240,441, filed June 17, 191 8. A shut-off valve 22 is inserted in the downwardly projecting neck between the outlet opening 18 and the joint, for the purpose of preventing escape prevent possible leakage to the pump when the machine is traveling. The handle 23 of this valve is located near the bottom of the tank, in the vicinity of the other parts controlled by the operator on the pavement The other member of the automatic oint includes a truncated conical head 24 on the vertical stem or inlet branch 25 "of a T fitting 26. Said stem passes loosely through an opening in a bracket 27 on the side of the vehicle frame, and the entire fitting is urged upward by a spring 28 resting on a ledge 1n the bracket and bearing agalnst the under side of the -head. At the rearof said-fitting is an outlet branch 29 containing a shut-off valve 30 and terminating in a swing nozzle 31 for returning liquid to the catch-bas n after'the cleaning has been completed, sa d nozzle being capable of being disposed at various degreesof downward and lateral inclination and of being turned upward when not in use. The bottom of the T body contains a removable cleaning plug32, and at its forward side is a rigid outlet branch section 33, through which water passes to the intake of the pump 13. Said pump 1s mounted on a platform bracket 34 projecting outwardly from the side of the vehicle frame forwardly of. the settling-bed, and preferably has its intake at the-front, connected with vertical and horizontal rigid conduit sections 35 and 36, the ends of the sections 36 and 33 being connected by a flexible hose length 37 which accommodates the up and down movements of the fitting 26.

The hydraulic ejectorelevator is preferably constituted of a telescopic discharge line 38 of rigid sections, a pressure line consisting of rigid sections 39 and 40 with an interposed flexible hose section 41, and an ejector 42 carried by and uniting the lower ends of said conduits, the ejector consisting ofa return bend casting containing a throat 43 at the bottom of the discharge line, an upwardly directed ejector jet nozzle 44 in alinement with the'throat, and a lateral suction intake 45 which may be prolonged downward to about the bottom of the bend by a short attachable nozzle 45.

The discharge line comprises an upper vertical" pipe section 46 supported at one side at the front ofthe settling-bed, a lower section 47 which issecured to the discharge limb of the ejector body and an intermediate section 48, the lower and intermediate sections being adapted to telescope within the when the tank is tilted and also to upper section when the ejector is raised, at which time the ejector and vertically movable pipe sections are sustained by a suitable fastening 49 connecting the ejector with the lower end of the upper section.

The upper end of said upper vertical section 46 is united by an elbow 50 with a horizontal conduit section 51 extending transversely inboard over the forward end of the tank, said section carrying at its far end a down-turned spout 52 arranged to deliver into the forward settling compartment of the settling-bed. The transverse conduit section 51-constitutes a slidable arm whereby the elevator can be disposed close to'the side of the vehicle .or moved outward to various operating distances therefrom. For this purpose the horizontal conduit is supported slidably in collars 53, 54 on brackets 55, 56

outer bracket 55 contains an anti-friction roller 57 supporting the under side of the slidable pipe, and the inner bracket 56 has a similar roller 58 at the top. The sliding conduit section is of such length'that when it is pushed in its spout 52 is adjacent and within the far side of the tank, and when the arm is pulled out as far as it will go, as Well as in any intermediate position, the spout still delivers into the forward settling compartment, The outer collar 53 is desirably split and provided with lever clamping nuts 59 to lock the arm against displacement when the vehicle is in movement. The elevator is raised and lowered, and drawn into the side of the vehicle when raised, by means of a suitable hoist comprising a winch 60 on the side of the settling-bed and a cable 61 passing therefrom upward and forward to a block pulley 62 on the upper forward portion of the tank, thence to a block 63 on the upper part of the discharge line, thence downward to a block 64 on the ejector, and back to the block 63.

The rigid section 39 of the pressure line is secured to the inlet limb of theejector and rises for a suitable distance alongside of the telescopic dischar e line. The other rigid pipe section 40 0 this line is connected to 'the pressure outlet 65 of the pump by a swlvel oint, which enables it to be swung in the longitudinal plane, this section being dlsposed at various degrees of downward inclinatlon as operating conditions may require. The free ends of the sections 39 and 40 are connected by the flexible hose section 41, of suflicient length to permit the maximum downward extension of the telescopic discharge line.

A small outlet fitting 66 is also connected wlth the pressure side of the pump, referably being attached to the swiveled el ow of the swinging conduit 40. This fitting is provided with a valve 67, whereby it can be opened and closed and receives a length of small flexible hose 68, constituting part of an agitator line. Secured to the end of this hose is a long rigid tube 69 of sufficient length to reach down into the basins, and constituting'both an agitator nozzle and a mechanical tool wherewith to work the deposits and to fend ofl obstructions from the intake of the ejector.

A suitable encased transmission 70 is provided for driving the pump and the dumping hoist fom the engine of the vehicle. This transmission may be varied and need not be described in detail. One control handle 71 enables the pump to be started and stopped it will, and another handle 72 controls the oist.

The tank has an inlet fitting 73 in its side near the top adapted to receive a hose for filling the tank from a hydrant or plug. An indicator pointer 74 on the same side of the tank, operated by a float, not shown, in the interior, indicates the amount on board.

The operation will be briefly described. Before starting operations the settling-bed tank is filled with water through the inlet 73 to within a suitable distance of the top, as indicated by the pointer 74. The filling hose is then disconnected and the vehicle proceeds, with the elevator raised and close to the side of the tank, to a basin or sump to be cleaned. Here the elevator is pulled out to such distances as may be necessary in order to position it over the opening, this operation being accomplished by virtue of the slidability of the horizontal continuation 51 of the discharge line in the brackets 55, 56. The fastening 49 is then opened and the winch 60 used to lower the movable sections 47, 48 of the telescopic discharge line, the ejector 42 and the section 39 of the pressure line into the basin, the lowering being continued until the ejector rests upon the bed of deposits. The valve 22 is now opened and the pump started. Water is withdrawn from the clear water compartment 12 of the settling-bed and forced downward through the pressure line 40, .41, 39 to the ejector nozzle in the basin, where a powerful upwardly directed ejector jet is created which draws inthe surrounding water and solids and impels them up through the telescopic discharge line 38 and its horizontal continuation 51 and out through the spout 52 into the first settling compartment of the tank. Separation of the liquid and solids is effected in the bed and the liquid is constantly withdrawn from the gutter by the pump to maintain the ejector jet. The attendant on the sidewalk uses the tube 69 to Work the contents of the basin hydraulically andme chanically and to mani ulate objects either to cause them to enter t eintake or to keep them away. The liquid discharged through sure line is swung so as to keep the hose section 41 free from bends. When the cleaning is finished, the pump is stopped and the valves 22 and 67 are closed and the elevator is raised and fastened at the side of the vehicle. The vehicle is then moved slightly, if necessary,'and the return nozzle 31 swung to a position in which it will deliver into the opening of the basin. Next the valve 30 is opened, permitting water to run back into.

the basin, in order that. it may be left charged with liquid and to conserve the carrying capacity of the tank. When a proper amount has been allowed to escape, as indicated by the pointer 74, leaving enough liquid in the settling-bed to start operations at the next basin, the said valve is closed and the nozzle can be swung to an upright position if desired. When not in use the tool .69 is supported in clips 75 on the side of the tank.

In case of the ejector becoming clo ged during cleaning, it is quickly cleanetI by stopping thepump, whereupon the column of water in the discharge line falls back and expels the obstruction.
