To all whom it may concern:
Be it known that l[, Gnonon W. OTTERSON, a citizen of the United States, and a resident of Seattle, in the county of King and State of Washington, havc'invented certain new and useful Improvements in Portable Apparatus for Cleaning Out Catch-Basins, of which the following is a specification.
The object of this invention is to provide an efibctive and economical apparatus for cleaning out city catch-basins. Under the usual practice accumulations are removed from these catch-basins either by the use of long-handled dippers or by hoisting it out with buckets into which the material is shoveled.
My Reissue Patent 14,324 of December traveling apparatus whereby the catch-basins are cleaned by means of a raisable and lowerable hydraulic ejector elevator mounted on a vehicle, forcing the liquid and solids upward into a settling bed, from which the force pump" of the ejector derives its supply and in which the solids are transported away, after the liquid or a portion thereof has been returned into the sewer. The present invention comprises certain improvements in this type of apparatus, having for their objects to provide an advantageous mechanical mounting for the ejector elevator permitting an extensive range of vertical movement. to enable the settling bed to be dumped without dis.- turbing the operating parts, and to provide an efl'ective means for agitating the contents of the catch-basins while the ejector is in operation.
In the accompanying drawings illustrating the invention:
Figure 1 is a side elevation of an embodi- Incnt of the invention, the hydraulic elevator being shown lowered into a catch-basin, its ejector and the catch-basin being in vertical section;
Fig. 2 is a plan view;
Fig. 3 is a rear elevation of the settling bed tank;
Fig. 4 is a side elevation of this tank, broken lines being used to show the tank in the act of being tilted for dumping;
Fig. 5 is a vertical transverse section through the rear portion of the settling bed tank;
Fig. 6 is a side elevation of a portion of the apparatus, showing the elevator raised;
7 is a section on the line 7-7 of Fig. 8 is a detail view of the pump drive;
ig. 9 is a side elevation, somewhat diagrammatlc, of another embodiment of the invention; and
Fig. 10 is a plan view of the same. In carryin out theinvention ll preferably make use 0 a motor-driven vehicle for transporting the hydraulic ejector elevator with its pressure and discharge lines and a force pump connected with the former and a supply ofwater for priming th pump. The vehicle 1 of Figs. 1 to 5 is provided with a rectangular tank body 2, constituting a settling bed. The elevator is mounted on one side oi the vehicle and comprises an ejector 3 having a jet nozzle 4: delivering in line with a throat 5, the material to be ejected being admitted through a suction intake 6. ressure and discharge lines 7 and 8 connect with the ejector and permit it to be lowered into and raised from the catchbasins. The discharge line 8 comprises upper and lower rigid sections 9 and 10, the lower section being adapted to slide within a suitable joint 11 at the lower end of the upper section, and the upper section being itself slidable within a 12 on the vehicle. The upper section of this piping terminates in a spout 13, arranged to deliver its stream into the main portion of theinterior oi the tank 2 adjacent the forward end of the same. The pressure line comprises a lower, rigid section 7, approximately the length of the section 10 of inc 8, and an upper flexible or hose section 7* which connects the rigid section with the outlet of a rotary force pump 15 mounted on the vehicle frame.
The described telescopic construction and slidable mounting of the discharge line, in conjunction with the flexible section of the pressure line, enable the elevator to be lowered and raised vertically intoand out of the catch-basins without rising to an undue height when elevated. The lowering and raising may be effected by means of a simple hoisting mechanism, designated generally by the numeral 14, the cable of which is attached to the ejector.
Provision is made for driving-the pump '15 from the vehicle-propelling motor 16.
In the illustrated arrangement there is a sprocket wheel 17 loose on the vehicle proguide or mounting lllll peller shaft and adapted to be coupled therewith by means of a clutch 18 having suitable operating means 19, and this sprocket is connected by a chain 20 with another sprocket wheel 21 on a lay shaft 22, from which a belt 23 passes to a pulley on the pump shaft.
The hydraulic ejector has an agitator outlet for loosenin the accumulations in the catch-basins, an in conjunction therewith ro'tary means for changing the direction of the agitator stream, in order to reach the material at all sides. For this purpose an opening is formed in the top of the body of t e ejector 3, between the pressure and discharge lines 7 and S, and in this opening is secured a small tubular casing 24 having a plurality of radiating apertures or nozzles 25. A tubular distri buter valve 26, having a single opening 27 to register success'ively with the apertures, is mounted rotatably within this casing, wherein it may be turned by means of a vertical shaft 28. The said shaft is of suiiicient length to project upward above the manhole when the ejector is lowered into a catch-basin, and is provided at its upper end with a suitable handle 29 above a guide 30 on the upper section 9 of the discharge line8, wherein the rod slides when the pipe isextended or shortened.
j The pump draws its supply from the tank 2 through a pipe line leading from the forward end of the tank near the bottom thereof. This line preferably confines two suitably connected sections 31 and 31, of which the first extends lengthwise within the gutter 37, hereinafter specified, having its forward end adapted to be opened and closed by a valve 32. The rear end of this pipe section passes downward through the bottom of the tank, or is connected to a suitable fitting, and beneath the tank is shown as rotatably jointed to the rear end of the section 31, which extends to the inlet of the ump. The axis of this joint 31 is coincident with the axis of the pivotal support 56 of the tank, of which mention will be made hereafter, so that the connection between the pump and tank need not be broken in order to dump.
In this instance the tank body 2 constitutes a settling bed wherein a rough separation of the liquids and solids elevated from the catch-basin is effected, the excess liquid being returned into the sewer through a line 34 which connects with the forward ortion of the tank, preferably at a greater height than the pi e 4, and is provided with a suitable inlet va ve 35.
The interior of the tank is divided by a l longitudinal partition 36 placed close to one side of. the tank and extending from the forward wall to within a short distance of the back wall, thus forming a gutter 37 which communicates at its rear end with the main portion of the interior of the tank. The pipes 31 and 34, heretofore mentioned, connect with the forward end of this gutter.
The main body of the tank is provided with a plurality of transverse bafiles 38, 39 and 40, which aid in causing the liquid to throw down its solids before entering the rear end of the gutter 37. Of these the baffles 38 and 39 are preferably formed with large openings 41, located in the upper portions of these bafiles and in staggered relation to each other, while the baflie 40 is preferably provided with a multiplicity of comparatively small perforations 42. The rear end of the gutter 37 is guarded by a bafile 43, which extends from the bottom of the tank part way upward toward the top and the height of which may be increased as the material accumulates in the tank by a supplementary baffle 44, which at first may be moved away from the entrance to the gutter.
In order to permit the solids to be dumped by an endwise tilting movement of the settling 'bed, the baflies 3840 are swingingly supported by hanging them from rods 45, which preferably rest in open slots in bracket lugs 46 on the side walls of the tank. The bafile plates 43 and 44 are similarly hung from a rod 47, to which they are connected by hangers 48 and 48 As thus mounted the baffles normally hang vertically by their own weight and are removable by simply lifting them out. The partition 36 being also removable by taking out bolts 50 which fasten it in place, the settling bed is capable of ready conversion into a cargocarrying receptacle.
The rear wall of the tank is formed by an end gate 51, hingedly supported at the top as indicated at 52, so as to be capable of swinging outward at the bottom when the tank is tilted for dumping. This gauwhen closed is held tightly to a suitable seat against the rear ends of the bottom and side walls of the tank by means of clamping (levices 53 and also by a holding bar 54, which latter is pivoted at its center to the gate and coiiperates. at its end with slotted keepers 55 on the side walls of the tank.
The tilting of the settling bed tank about its rearwardly disposed pivot 56 may be effected by any of the appropriate means for such purposes, such as a hydraulic jack. 57.
In the use of this form of the apparatus it will be understood that the vehicle starts upon its rounds with a suflicient supply of water in the tank 2 to prime the pump. When a catch basin is reached the manhole cover is removed and the ejector elevator lowered into the catch-basin until its ejector portion rests upon the material therein. The pump 15 is then coupled with the propeller shaft of the vehicle, so that a stream of water Stl is drawn from the tank and forced downward through the pressure line 7 to'the jet passage or nozzle 4, whereby a high velocity jet is created which sucks in the material through the intake 6 and impels it upward through the discharge line 8 into the forward end of the main portion of. the settling bed. Here the Water gradually finds its way rearward through the openings in the ba es and around their edges until it reaches the rear end of the gutter 37, by which time it has of the solids. From this gutter the pump continues to draw its supply throughout the operation, and at the conclusion the valve 35 is opened so as to permit the water remaining in the tank, or the excess amount which is not needed for priming the pump at the next catch-basin, to flow back into the sewer through the line 34. ing and elevating action paratively small agitating jet is delivered in difi'erent directions from the outlet 24, so as to loosen the accumulations, thereby facilitating their removal. When the apparatus has visited a number of catch-basins and the settling bed is as full of solids as is desirable, the vehicle proceeds to an appropriate spot to dum its load. This is accomplished by releasing the end gate and by elevating the forward end of the tank, which done, the bathes and the end ate swing freely and permit the materia to slide rearward out of the tank.
Figs. 9 and 10 illustrate the fact that portable settling beds, such as-contemplated by the invention, may be mounted upon separate, auxiliary vehicles. This development of the invention may be carried out in various ways, and, of course, there may be more than one of these auxiliary vehicles for use with the main vehicle, and the auxiliary vehicles may be equipped with selfpropelling mechanism, or, as illustrated here 1n, they may be in the nature of trailers. The main vehicle is designated 1, and, in addition to the hydraulic ejector elevator and pump, carries a tank 2*, which in this instance is not used for settling and is there fore of comparatively small size, since it is required to carry only suihcient water for priming the pump 15, which may be driven as before and the inlet of which is connected with this tank by a pipe 31.
The trailer 1*, suitably coupled with the main vehicle, carries a settling bed tank 2 which is here shown diagrammatically, but will be understood as being substantially like the tank 2 heretofore described and having like capabilities in respect to dumping. The spout 13 of the hydraulic elevator is extended rearward, so as to discharge into the forward end of the bamed portion of the tank 2". From the forward end of the gutter 37* a detachable hose connection 81 conproceeds a comdeposited practically all While the ej ectdischarge lines,
ing in a spout and being of telescopic conducts the water from the settling bed to the tank 2 to replenish the supply for the ump when the apparatus is in operation. alves 58 and 59 may be used to close the corre; spondmg openings in the tanks when the vehicles are separated. The line 34 for returning the water into the sewer may lead from the gutter 37 as before. As in the other embodiment of the invention, the valve 35 controlling this line is preferably opened only after the conclusion of the operation of cleaning out a catch-basin, since the ejecting action is mostefl'ective when there is little water in the basin.
