Definitions

  • VEHICLE FOR CLEANING STREETS y Filed Nov. 13, 1957 INVENTOR /52/5 /ara/xf' BY @MM f, 10Q/hf ATTORNEY United States rhe present invention relates to a road cleaning vehicle.
  • a further object of the present invention is to provide a new street-cleaning vehicleuwhich wets the vdirt or rubbish on the road, which sweeps thel dirt substantially to one point, and which then sucks up the dirt in its wet condition.
  • Another object of the present invention is to provide a vehicle for carrying out the street-cleaning operation very economically despite the use of large quantities of water for wetting the dirt on the road.
  • a further object of the present invention is to provide a vehicle or" the most functional design and the most effective weight distribution attainable.
  • An important feature of the present invention therefore consists in the provision of a motor vehicle which is capable of first mixing the dirt on the road with Water so as to form a watery mixture and then sucking up 'such mixture, for example, by drawing it into a collecting tank mounted on a motor vehicle.
  • the watery mixture thus collected in the tank may then be separated within said tank into solid particles and soiled water by allowing the solid particles to settle in the vehicle tank by tgravity.
  • Another feature of the invention consists in the subsequent removal of the soiled water from the collecting tank, in thereafter against sucking another quantity of watery mud mixture from the street into the collecting tank and again separating the same therein into relatively solid mud and soiled water, in continuing this operation until the container is filled with relatively solid mud to a certain capacity, and in then removing the mud from the container.
  • a further object of the present invention is to provide a scrubbing and sweeping mechanism by means of which the muddy water, before it is sucked up, is scrubbed off the street and guided to the suction device which may be disposed, for example, in front of, laterally of, orV
  • Another object of the invention is to provide means for permittingthe soiled water after Ithe solid dirt particles have been separated therefrom and preferably after having been cleaned by a filter, to be used againfor wetting the dirt on the road. It will thus be possible to use a relatively small quantity of fresh water or, in other words, to make one filling of the fresh water container last for an extended operating period of the vehicle. Therefore, the term fresh water employed here does not indicate Vpure water only, but also water mixed with mud. p l
  • Another important object of the present invention consists in designing ,the street-cleaning vehicle in such a manner ⁇ that the center of gravity of the entire tank structure containing the fresh-water container and the container for the muddy mixture'remains either substantially the same or varies but slightly no matter whetherthe fresh-water container is filled and the mud container is empty or the mud container is filled and the arent @f fresh lwater container is empty.
  • the tank may be designed so that the two containers therein overlap each other in the longitudinal direction of the tank, for example, by providing at least one diagonal or horizontal partition inside of the tank which separates the tank into containers lying substantially one above the other.
  • FIG. 1 illustrates a side view of a vehicle with a collecting tank thereon shown in cross section;
  • FIG. 2 illustrates a cross section of the tank taken along line 2 2 of FIG. l;
  • FIG; 3 illustrates a plan view of the washing and sweeping mechanism
  • FIG. 4 illustrates a similar plan view of a modification of the washing and sweeping mechanism.
  • the street-cleaning vehicle consists of a truck having a chassis 10, and a tank 12 mounted thereon behind the drivers cab 11.
  • a partition 13 extending diagonally from a point near the upper front end of the tank to a point near ⁇ its lower rear end of the tank is divided into a front container 14 substantially disposed underneath partition 13, and a rear container 15, substantially disposed above the partition.
  • the front container l14 serves as a fresh-water container and is accessible, for example, through yan opening 16 at the top which may be provided with a suitable cover, while the rear container 15 serves as a mud container and is also provided with an opening 17 which can be closed by a cover.
  • a scrubbing or sweeping brush 18 is mounted on chassis 10 between the front and rear wheels of the vehicle and, while the vehicle is being driven, this'brush 18 is rotated by suitable driving means, not shown, in the direction indicated by the arrow.
  • a spraying or flushing mechanism which substantially consists of a pipe 19 extending parallel to brush 18.
  • This pipe 19 is connected to the fresh-Water container 14 by means of pipe 32 and through a plurality of openings along its length, sprays powerful jets of Water directly upon the road Valong lthe entire length of the brush.
  • a suction device 20 is mounted on chassis 10 which is connected with the interior of the mud container 15 by means of a pipe 2x1.
  • a vacuum or suction pump 22 ismounted in a separate compartment which forms a recess in the fresh-Water container behind the drivers seat and may, for example, be coupled to the engine of the vehicle.
  • Pump 22 is connected by means of -pipe 31 -to the inside ⁇ of mud container 15, which is sealed tightly toward the outside for maintaining a vacuum therein. tends through pipe 21 to suction device 20.
  • av -ap 23 is hinged so as to swing upwardly to permit the mud to berremoved from container .15.
  • the flap is pressed tightly against the rear Wall of tank 12 by suitable, easily'released means, such as bolts or the like so as to seal container 15.
  • the upper part of container -15 also contains a device yfor emptying the soiled 'water therefrom.
  • This device consists of a pipe 27 which is mounted on a side wallv of container 15 so as to be pivotable at 25 about a horizontal axis by means tof a handle 26 or the like.
  • yPipe 27 is connected to a hose 28 through which the muddy vwater may be con- This vacuum also exducted to a suitable place, for example, a sewer or ditch.
  • the front container 14 is filled with fresh water, while the rear mud container 15 is empty. VInV this case, the center of gravity of the entire tank is located approximately at the point S1.
  • the fresh water is gradually drained from container i4 through the spraying or flushing mechanism 19 and thus sprayed upon the road where it becomes mixed with the dirt on the road.
  • the muddy water thus formed is conveyed diagonally outward by the rotary brush 1S in the direction of the arrow p and conducted :toward the suction device 20 at the outer end of brush 18 and facing in the direction of rotation x.
  • the muddy water is then sucked up by the suction device 20 and drawn into the mud container 15 by the effect of the vacuum within the container.
  • the pivotable pipe 27 which serves for draining the soiled water from container 15 is preferably ad ⁇ justed to a position in which its inlet opening will be disposed slightly above the level 3l. of the mud so that the soiled water 30 above the mud level 3l may be drained 0E through hose 28 into a ditch, sewer, or the like, and the space within container l5 thus becoming empty will become available for receiving additional muddy water.
  • the draining may be effected by gravity or by means of a pump, for example, by ⁇ a suitable connection to suction pump 22.
  • the drainage may also be carried out automatically, for example, by means of a float with an inlet thereon which is connected to hose 28 and adjusts itself.
  • the center of gravity will shift only a relatively short distance during one complete cycle of operation.
  • the center of gravity is located substantially at the point S1
  • it will shift during the operation gradually toward the rear so that, when the fresh Water container 14 is empty and the mud container l5 is filled to its normal capacity, the ⁇ center of gravity will be located substantially at the point S2.
  • the weight distribution of the vehicle is preferably designed so that the distance between these two points S1 and S2 will be no larger than one-fifth to a maximum of onefourth of the total length of the entire tank 12.
  • FIG. 4 illustrates a modification of the invention in which the rotary brush is divided into two separate brushes, namely, a main brush 18a and a supplementary brush 13b at the outer end of brush 18a and coaxial therewith.
  • the invention may also be modied by providing two rotary brushes at opposite oblique angles relative to the direction of :travel of the vehicle, that is, in a V-shaped arrangement converging toward the rear, and rotatable in opposite directions to each other.
  • the suction device 20 would then be mounted centrally between or behind the converging ends of the two brushes.
  • this water may also be utilized again for washing the road.
  • a suitable switching valve 36 is provided which permits either the fresh Water remaining in container 14 or the soiled water from container 15 to be used alone or to be mixed with each other before being passed to spraying device 19.
