Abstract: 453,902. Washing and cleaning vehicles. PIQUEREZ, E., 4, Avenue de la Pommeraie, Saint Cloud, France. March 27, 1935, No. 9626. Convention date, Dec. 26, 1934. [Class 138 (i)] [See also Groups X, XVIII, XXVIII, and XXX] A garage is provided with a main floor occupied by various serviceing stations for washing, removing used oil, re-lubricating and effecting various adjustments and repairs, roller-conveyers associated with the floor for transporting vehicles through selected stations, sumps under the floor at selected stations, and a space under the floor housing the main bulk of the treatment apparatus including water and oil-tanks and pressure-producing means for the washing and oiling means. The layout of the floor is such that any car can be submitted to all of the operations in turn, or to any selected operations, without interfering with the progress of other cars through the system. Fig. 1 shows the plan of a lay-out comprising two brake-adjusting stations 1 arranged in parallel, a pair of sump and gearbox emptying and re-filling stations 2, three parallel washing, dust-removing and chassislubricating stations 3 and a final station 4 for effecting minor repairs. From the tracks shown in dotted lines it is apparent that a car may be treated at stations 1 and 2 or pass through either or both without treatment, and that it can be run out to one side of the apparatus after leaving either of these stations, without undergoing further treatment. Similarly a car can receive treatment in or byepass stations 3 and 4. All the treating apparatus is housed in one long underground compartment accessible to lorries. At station 2 the used oil is run by gravity into containers 11, Fig. 4, while fresh oil for the engine and for the gear-boxes and back axles is forced by compressed air from the containers 12, 13 respectively. All the containers are mounted on a staging 16 for loading on to and unloading from lorries. At station 3, the cars are traversed by a conveyer formed by two parallel wheel-receiving tracks of driven rollers. The lower parts of the chassis are first washed with water at high dressure at the point 31, Fig. 6. Water drawn from the reservoir 25 is forced by a pump into a main 27 fitted with hoses 28. The used water is collected in the tank 21 from which it overflows into a filter 23 and is drawn from thence into the reservoir 25. Plugs 36 can be removed to clean out the tank, preferably discharging the mud directly into lorries. At the point 32 the body is washed with water at a lower pressure by the hoses 30 communicating with a second piping system, and pump. At point 33 draining occurs, assisted if necessary by compressed air supplied through main 34. At point 35, the body is wiped and internal dusting of the body and lubrication of the chassis commences. The dusting is performed by suction nozzles 40, Fig. 8, actuated by a pump 41 with an interposed filter 42. Lubricating guns 45 are fed from the reservoir 43 through the pipes 44 by the aid of compressed air. At the final station a lubricating-apparatus is fitted underground to reach any part which may still require attention. The arrangement illustrated is merely preferential, as the number of the stations might be increased, their order might be changed, they could be arranged in a curve instead of a straight line and different stations could be at different levels. Specification 445,445, [Group XXX], is referred to.
