Yet another object of the present invention is to provide a washing apparatus mounted in a van truck having a water softener and a water heater selectably connected to a pair of storage tanks or to an inlet water hose.
In conjunction with the above object it is an object of the present invention to provide a mobile washing apparatus having chemical injectors for injecting chemicals into the water outlet hose.
Related objects and advantages of the present invention will be apparent from the following description.
BRIEF DESCRIPTION OF THE DRAWING FIG. 6 is a fragmentary schematic view of one of the I chemical injectors of the present invention.
FIG. 7 is a fragmentary perspective view of one of the high pressure outlet hoses having an electrical switch box thereon.
DESCRIPTION OF THE PREFERRED EMBODIMENT For the purposes of promoting an understanding of the principles of the invention, reference will now be made to the embodiment illustrated in the drawing and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended, such alterations and further modifications in the illustrated device, and such further applications of the principles of the invention as illustrated therein being contemplated as would normally occur to one skilled in the art to which the invention relates.
Referring now more particularly to the drawings,
there is shown a mobile washing apparatus 15 with a conventional van truck 16 having a driver compartment as well as a rear compartment wherein a pair of storage tanks 17 and 19 are mounted within the van. Tank 17 extends along side 18 of the van and is spaced apart a distance 21 from tank 19 which extends along side 20 of the van. The space 21 between the tanks serve as a storage area and allows a person to walk between the tanks from the driver compartment toward the back doors 28 which are hingedly mounted to the van. Each tank is mounted to floor 27 by a plurality of legs 36 (FIG. 3).
FIG. 2 is a floor plan of a portion of the truck of FIG. 1 whereas FIG. 3 is a view taken along a line and looking in the direction of the an'ows-3-3 of FIG. 2. FIG. 4 is a schematic diagram of the various water lines connected within the van. As will be evident from the following description relative to FIGS. 1 through 4, water may be stored within tanks 17 and 19 and then routed to a pair-of water softener tanksfor treatment of the water prior to insertion into a hot water tank coupled with a gas fired water heater. A water meter is provided to measure the flow of water from an inlet hose and form the p'airof storage tanksto the water softener tank. Various valves are provided to control the flow of water from the hot water tank and from the softener tank to a pair of high pressure pumps which force cold water and/or hot water through a pair of high pressure hoses with nozzles mounted atop the storage tank and extendable through the back doors of the'van. As will bedescribed, chemicals may be injected into the water prior to the water exiting the high pressure hoses. An
electrical generator coupled to the transmission of the truck provides the electrical energy required for the various pumps and switches of the apparatus,
The inlet hose assembly 29 (FIGS. 3 4) is fixedly mounted atop storage tank 17 and has an inlet hose 30 wound on reel 32 which is rotatablymounted between upstanding brackets 31. Beneath inlet hose 30 is a high pressure outlet hose 33'wound on reel 34 also rotatably mounted to brackets 31. Reel 32 may be rotated so that hose may be extended through the rear of the truck being connectable to an external source of water. The inlet hose is connected by coupling 37 to inlet pipe 38 which extends downwardly from reel 32 and horizontally. along the length of tank 17 where it isconnected to pipe 39 by a T-joint coupling 41. Pipe 39 has a top end connected to a right angle coupling 40 which Valve 48 (FIG. 2) is provided adjacent outlet 50 so as to control the flow of water from tank 17. An identical valve 49 (FIG. 4) is provided for tank 19 to control the flowof water therefrom. Thus, as water enters tank 17 from inlet hose 30, water will flow from tank 17 through pipe 47 (FIGS. 2 and 4) and into tank 19 through outlet 51. Of course, valves 48 and 49 are in the open position to allow water flow from tank 17 to tank 19. Thus, both tanks may be simultaneously filled with a single inlet hose or if desired valves 48 and 49 a may be closed to enable only tank 17 to be filled. Suitable baflling (not shown) is provided within each storage tank to prevent the water therein from moving violently as the truck is driven on a road.
FIG. 5 is a fragmentary perspective view of float assembly 43 which is mounted along with valve 42 to tank 17. Assembly 43 has a housing 56 sealingly mountedto tank 17 and coupled to inlet pipe 41. The outlet 57 of pipe 41 is closed by seal 61 whenever float 60 is pivoted to its most upward position. As the water level within tank 17 moves downwardly, float 60 also moves downwardly being guided by cylindrical float guide 59. Float 60 is mounted to a brass rod 58 hingedly mounted to pipe 41. As the float 60 moves downwardly seal 61 moves away from outlet 51 thereby allowing water flow into the tank. Likewise, as float v moves upwardly seal 61 is positioned adjacent to the outlet 51 thereby preventing water flow into the tanks.-
A pair of water softener tanks 22 (FIG. 2) are mounted within the truck and are connected in tandem so as to controllably receive water from storage tanks 17 and 19. A water meter 45 is also mounted in the truck so as to measure the water flow from the storage tanks 17 and 19 as well as the inlet hose 30 to water softener tanks 22. The outlets 50 and 51 (FIG. 4). of storage tanks 17 and 19m interconnected together to 7 meter 45 by pipes 47 and 47' with apressure booster 1 pump 24 connected therebetween. T-coupling 44 con-.
When an external source of water is accessible at the working site, the inlet hose may be coupled to the.
source and valve 42 may be closed thereby bypassing tanks 17 and 19 and routing the incoming water directly through meter 45 to the softener tanks 22. 'Ofcourse, meter 45 will measure the amount of water taken from the external source of supply. In cases the storage tanks: through meter 45 to thesoftenertanks 22. Valve 54 is toinlet pipe 38 and should be positioned closed when fillingtanks l7 and 19 through'float assembly 43 or whenever valves 48 and/or 49 are in the open position. Valve 54 should be in the open position when it is desired to route the incoming water from inlet hose 3o past tanks 17 and 19 directly to meter 45. I
It is desirable to provide a means for emptying tanks 17 and 19 through inlet pipe 38 and inlet hose 30 while bypassing meter 45. Therefore, a bypass outlet pipe, 53
is coupled to inlet pipe 38 and between a bypass valve 52 and the inlet side of meter 45. Valves 52 and 62 are provided to'direct the flow of water. For example, valve 52 is mounted between pump 24 and meter 45 and should be in the open position whenever pump is utilized. Likewise, valve 52 should be closed whenever pump 24 is not required. Valve 62 is connected to ont-v let pipe 53 and should be open with valve 63 of softener tanks 22 being closed whenever it is desired to empty water from tanks 17 and 19 through pipes 53 and Likewise, valve 62 should be closed and valves 63 should be open whenever it is desired to allow water to V flow through meter 45 to the softener tanks.
The water within tank 23 is circulated through heater 25 by pump 26 connected between tank 23 and heater 25 to pipe 71. The water forced into heater 25 by pump 26 is then returned by pipe 72 to tank 23 which empties into hot water pipe 68. A variety of pumps may be utilized to circulate the water from the hot water tank to the heater. Excellent results have been obtained by utilizing a pump produced by Bell & Gossett Company of Morton Grove, 11]., under Model No. 125. Heater 25 purchased from the A. O. Smith Corporation of Kankakee, Ill., under Model No. BC300. A flue (not shown) is mounted to heater extending through the roof of the truck allowing residual gases to be expelled into the atmosphere. A suitable thermostat and igniter is provided for the gas fired heater. Thus, cold water is provided in pipe 66 while hot water is provided in pipe 68. Both pipes 66 and 68 extend toward the rear portion of the truck.
Each high pressure output hose has a switch box mounted to its outlet to control the flow of fluid. For example, hose 33 has switch box with a temperature switch 96, a chemical switch 99 and an ofilon switch 98. Switch 96 is a two position switch connecting electrical energy to solenoid valves 78 and 79. When switch 96 is turned to the cold position, solenoid valves 78 and 79 respectively open and close thereby routing only cold water to pipe 90. When switch 96 is turned to the hot position, solenoid valves 78 and 79 respectively close and open thereby routing only hot water to pipe 90. Switch 98 is a push button, two position switch which connects a source of electrical energy to high pressure pump 80. Chemical switch 99 is a multiple position rotary switch for connecting a source of electrical energy to the chemical pump of injector 89. A conduit 97 encloses the wiring from switches 96-99 to the valves, pumps and source of electrical'energy. A similar control box controls solenoid valves 73 and 74, high pressure pump 81 and the chemical pump for injector 88.
As previously mentioned, an electrical generator 100 (FIGS. 2 and 3) is mountedwithin the truck being operably driven by the transmission of the truck. Generator 100 is mounted to floor 27 having an input drive shaft 101 with a gear 102 in meshing engagement with a suitable sized gear on transmission shaft 103.
With the truck in a stationary position and with the engine running, the transmission may be put into gear so as to drive generator 100. Such a generator with the required coupling gear is produced by the Generator ONAN Division of the Studebaker Corporation of Minneapolis, Minnesota under Model No. lOUP-4XN/1A. The electrical energy provided by the generator may be utilized to power the various pumps, switches and solenoid valves as well as various air heaters and lights within the truck. Such a generator is a 10 KVA, 440 volt, three phase device and thus suitable stepdown transformers must be utilized to convert the electrical energy into a suitable level for use with the pump and lights.
