SANITARY CLEANING EQUIPMENT Filed NOV. 29, 1946 2 SPEETS-SI'IEET 2 INVENTOR. E/Z'0/7 5. oung Patented May 6, 1952 UNITED STATES P TENT ()FFICE' 3 Claims.
My invention relates to cleaning apparatus and more particularly to apparatus for cleaning cesspools, septic tanks, toilets and the like.
The object of my invention is to provide a cleaning apparatus of the class indicated above and adapted to be permanently mounted in a body on the back of a truck chassis.
Another object of my invention is to provide an apparatus of the character indicated above, which can be placed on any convenient place in a street or an alley while operating, and which can be connected with the tank or the like to be cleaned by means of a three inch hose to empty and clean said tank, eliminating all foul odors and the spreading of disease germs by spilling some of the contents removed from the tank or the like.
Other objects of my invention may appear in the following specification describing my invention with reference to the accompanying drawings illustrating a preferred embodiment of my invention.
It is however to be understood, that my invention is not to be limited or restricted to the,
exact construction and combination of parts described in the specification and shown in the drawings, but that such changes and modifications can be made, which fall within the scope of the claims appended hereto.
In the drawings- Figure 1 is a sectional view taken on the vertical longitudinal center plane of the cleaning apparatus according to my invention.
Figure 2 is a sectional view taken on line 22 in Figure 1, and
Figure 3 is a sectional view taken on line 33 in Figure 1.
Referring now in detail to the drawings the cleaning apparatus forming the subject matter of my invention comprises a boiler or tank l adapted to be installed or mounted permanently on a truck or the like (not shown).
An opening is arranged in the top of the shell of the tank Ill and is located approximately symmetrically about the intersection of the vertical longitudinal and transverse center planes of the tank. A receiving box II is fastened to the top of the tank shell and surrounds the opening therein. A lid or cover I2 is hingedly attached to the upper end of the receiving box II and is adapted to close the same.
Adjacent the front end of the tank H] a power plant I3 is mounted on top of the tank I0 comprising a fly wheel I4 adapted to actuate a pump construction I5. This pump construction has an intake or suction pipe I6 connected to its intake port, which is preferably a three inch pipe, extends rearwardly of the tank I0 and is secured to the outside thereof by one or more clamps ll.
To the outlet port I8 of the pump I5 an angularly bent outlet pipe or conduit I9 is secured extending through the front wall of the receiving box II and having its discharge end located inside the opening in the top of the tank l0.
Inside the tank l0, directly under the outlet pipe IS a partition plate is arranged and fastened to said tank. This partition plate 20 extends part way up in the tank In and a bafile plate 2| is pivotally mounted intermediate its ends, above the upper edge of the partition plate 20.
In the lower portion of the partition plate 20 an opening 22 is provided, adapted to be closed by a valve plate 23 slidably mounted on the partition plate 20 and forming valve means. An actuating rod or hand actuable means 24 is fastened to the valve plate 23, and extends upwardly therefrom into the receiving box where it is slidably mounted in a guide member 25, mounted on a side wall of said box. On its top the actuating rod 24 is provided with a handle 26 to facilitate the manipulation of the valve plate 23.
The rear end of the suction pipe I6 is provided with an outer thread 21.
A three inch hose 28, preferably about 200 feet long, is coupled to the suction pipe I6 and the power plant I3 is started, actuating the pump IS.
The pivotable baffle plate 2| is arranged, so that it is tilted forwardly and the valve plate 23 is pushed downwardly to close the opening 22 in the partition 20.
The free end of the hose 28 is inserted into the cess pool or the like to be cleaned. As long as mostly liquid is removed from the cess pool, the baflie plate 2| remains in the arrangement described above directing the liquid in the forward compartment of the tank Ill formed by the partition 20. When the contents of the cess pool being removed therefrom become more solid, the baffle plate 2| is tilted to incline rearwardly by making contact therewith through box. H with a stick or rod held in the hand or by the latter alone to forcibly tilt the bafile plate, so that the solid contents of the cess pool are directed into the rear compartment of the tank It.
While moving the cleaning apparatus the bafiie 5 plate 2| serves as a part of the partition 20 keeping the watery contents in the front tank compartment separated from the heavy sludge collected in the rear tank compartment.
For the process of unloading the cleaning apparatus a discharge outlet 29 is provided in the bottom of the rear tank compartment adjacent the rear end thereof. With this discharge a discharge elbow 30 is connected and a discharge valve 31 is connected with the elbow 30. An unloading hose 32 is adapted to be coupled to the discharge 3|.
When the rear tank compartment is emptied as far as possible, the valve plate 23 is pulled up permitting the liquid in the front tank compartment to flow through the rear tank compartment, thereby flushing this compartment clean.
For cleaning toilets having boxes the two tank compartments are filled with clean water. A hose 32 is attached to the outlet valve 3|, which is opened to let the water in the rear tank compartment flow into the toilet box. Then the outlet valve 31. is closed, the hose 28 is inserted in the toilet box and the pump I5 is started, sucking the contents out of the toilet box. The baflie plate 2| is arranged to direct the watery toilet contents into the rear tank compartment.
An outlet fixture 33 is provided on the bottom of the front tank compartment, and an outlet pipe 34 is connected therewith and extends rearwarclly of the tank, where an outlet valve 35 is connected therewith. A water hose 36 is attached to the water outlet valve 35.
When the watery contents of the toilet box are removed from said box, the water outlet valve 35 is opened and the water hose 35 manipulated to wash the toilet box clean.
In the rear wall of the tank It a man hole 31 is provided for cleaning purposes.
Having described my invention I claim as new and desire to secure by Letters Patent:
