Filed Mar. 10, 1959, Ser. No. 798,412
3 Claims (Cl. 134-107) This invention relates generally to machines for cleaning garbage can drums and the like, and more particularly to such a machine in which the drum is spun about a vertical axis while both inner and outer surfaces are scoured and rinsed with many jets of hot cleaning liquid.
Restaurants, hotels, hospitals and similar large residential institutions have a very dicult problem of maintaining sanitary conditions in their kitchen areas because of the huge volume of garbage which must be temporarily stored near such an area prior to its removal. The tonnage of garbage delivered by a medium sized restaurant is so great that mechanical disposal means or incinerators are not satisfactory.
Moreover, the older food particles which accumulate on the surfaces of the garbage cans may be retained there for a period of time corresponding to several garbage collection periods, and by decaying, develop powerful odors in the immediate vicinity of the food preparation area.
When the garbage cans or containers have accumulated even small quantities of residual waste material, which remains after a garbage collection, their powerful odor attracts a swarm of -ies even after the garbage has been collected, thus creating a severe danger of the spread of disease by the insects.
To combat these problems of unsanitary conditions, bad odor, and insect attraction, most modern restaurant facilities are compelled to clean the garbage containers, even after they have been emptied, by means of hoses, insecticide sprays, etc. In addition, there has been some relatively primitive advancement in the direction of servicing restaurant facilities by truck-carried tanks of spraying equipment.
The truck-carried or portable equipment is essential because it is not economically sound for most restaurant facilities to maintain large and cumbersome devices at the site of use at al1 times, not only because of economics, but also because of space and mechanical maintenance problems.
However, most truck transported and stationary garbage can cleaning means have left the major part of the hard work to manual labor. The operators must physically handle the iilthy drums and work over both their internal and external surfaces with hose sprays.
Another disadvantage of the sy'stems heretofore known, is that the filthy eiiluence of cleaning Water and entrained garbage is usually discharged at the site, often into an overloaded sewer where the accumulating garbage particles eventually create a problem.
-Another disadvantage of the waste of the discharge water is that powerful and valuable insecticides, soaps, and deodorizing materials are thereby lost after a single use, although they might be powerful enough to be suitable for several cleanings.
lt is the major object of the present invention to overcome the foregoing and other problems by means of a portable garbage container cleaner, suitable for mounting on a truck body, which can clean the drums by rnotor driven means and without manual handling except for loading the drum before cleaning and removing it from the machine after cleaning.
t It is another major object of theinvention to provide ICC a garbage drum cleaning machine in which the cleaning liquid, including all soaps, insecticides, and deodorants, can be recycled to the mechanical cleaning means until its strength is entirely used and exhausted.
Another important object of the invention is to provide a mechanical garbage drum cleaning means which is sufliciently llexible in structure to receive drums which vary slightly in size because of variation in manufacture or because of damage experienced during the rough handling to which such containers are frequently subjected.
The foregoing and other objects and advantages of the invention will best be understood from the following detailed description of one specie embodiment of the invention, taken in connection with the accompanying drawings, in which:
Figure l is a plan sectional view of the described embodiment of the invention, the plane of the section being taken approximately at the plane indicated by the numerals 1-1 in Figure 2; and
Figure 2 is a vertical sectional view as viewed at a plane through the lines indicated by the numerals 2--2 in Figure 1.
ln Figure l, the drum cleaning machine, indicated generally by the arrow 10 is seen to be comprised principally of a cylindrical drum cleaning tank 1l which is nested into a cleaning liquid reservoir 12.
A portable gasoline engine 13 is tted in closely at the right side of the tank 11 and drives a pump 14 and a sprocket 15 mounted on a power shaft 16 to operate other parts of the machine 10, as will be described in detail hereinafter.
The operator may conveniently stand beside both the cleaning tank 11 and the engine 13 and reach the control handle 17 by means of which he may operate a l clutch 18 for connecting or disconnecting the power shaft 16 to the engine 13. i
As seen in Figure 2, the cleaning tank 11 is supported at a somewhat higher elevation than the liquid reservoir 12 by means of a framework of angle iron 20, and the bottom region of the container ll is in open communiction with the interior of the reservoir 12 through a liquid return opening 2l.
The reservoir 12 contains a cleaning liquid as indicated at 22 which is preferably a water solution of a strong liquid soap or detergent, some powerful insecticide such as DDT or chlorodane, a commercial deodorant, and a small amount of pine oil or the like to impart a pleasant odor to the cleaned garbage drums.
The uppensurface of the liquid 22 must not be so high as to impede the spraying operation which takes place inside the cleaning tank 11, and which will be described hereinafter.
The liquid 22 may be drained away by means of the drain valve 23 when the efficacy of theliquid is exhausted.
Preferably, the truck carries a butane -fuel tank which is connected to gas burner supply line 24 and supplies burners 25 and 26, seen in dashed outline in Figure l, and in end view in Figure 2, which burners, when lighted, are sufficient to raise the liquid 22 to or very near the boiling point.
The pump 14 withdraws cleaning liquid from the reservoir 12 by way of an intake line 30, and delivers it under pressure of 60 or more pounds per square inch to a pressure discharge line 31, for delivery to the various spray lines to be described hereinafter.
The intake line 30 is provided with a strainer 32 at the intake in the reservoir 12, but inevitably, many hard chunks of garbage particles pass through the pump. Not only must the pump 14 be of a type which can withstand y the passage of some `solid materials, but the discharge line 31 and parts of the apparatus downstream from it must be protected against the possibility of clogging and" development of over pressure in the discharge line 31.
Consequently, .a'bypass ,lineis provided for returningA thecleaning liquid directly,. from the pump-dischargerto the. reservoir 12, byway of a safety valve 34; whenever the pressure in dischargeline 14 exceeds-a predeterminedl safevalue.`
The extremelyeicientcleaning achievedby the invention is accomplished by spinning the garbagedrum. invaninverted position withinthe drum cleaning tank 11, as indicated in Figure 2, while scouring and rinsing both` itsainternal and external surfaces withpowerfuljets of.l
hot and steaming cleaning liquid.
Aheavy bearing 40V is welded to .the underside of theV bottorrrof the tank 11, and a short, vertically disposed hollowshaft 41 is rotatably mounted therein. yIt is irnportantto provide good liquid seals 42y and 43 to prevent unwanted leakage of liquid from within the cleaning,
tanky 11 to the work floor44, where it would wet the feet of the operator and make the work oor dangerously.
slippery. Y
The hollow shaft 41 has a suitable upper shoulder 45" to holdvit in position, and has a bevel gear 46 keyedv and fastened to its lowerand externalend.
A small bevel pinion 47 is rotatably supported in a:
bracket 48 on the bottom ofthe-tank 11, and. rotates with a small sprocket 49-Which is driven through a chain v50 (see Figure l) by sprocket 15 on power shaft 16, as already described.
n the upper portion thereof, the hollow shaft 41, inside the lower part of the drum cleaning tank 11, carries at its upper end a set of resilient gripping means, indi# cated generally by the numeral 51, for firmly holding the,
inverted garbage drum, indicated by the phantom lines,
cord -bars -are omitted from the illustration yof Figure 2 for purposes of clarity.
It willbe seen that the resilient construction of theV retaining means 51 will grip the `interior surface of garbagedrums whichvarysubstantially in sizefrom the preferred standard. on. the device by simply invertingit onto Vthe cord supporting bars 59 and retaining. it thereon by -means of the, engagement between ,the resilient spring `ngers 58 and itsv external surface.
The. hot liquidis delivered inv sprays to the Vsurfaces ofthe` drum' 52 by way of-an internal axial spray line` 61 and an external spray line 62. An internal scouringv spray line 63 is also provided for purposes. to be -described hereinafter. The hot liquid under pressure lows from the pressure line 31 to thevalve 64 (seeFigure l), and.is delivered from that point to .two horizontal pipes.A 65.`
and 66. Y
Supply pipe 65 is connected to an elbow 67 which dis-- charges upwardly' through the vertically disposed axial spray line61, which is supportedr at -elbow..67 so. as.to stand free and stationary within the hollowshaft 41- At its upper and lower endg-the` axial sprayline is provided with radial lines 68 and 69 which deliver-liquid` tothe scouring line 631 Preferably, the line 61`gis broken byy a plumbers coupling.70.to make aeasy-assembly vand disassembly.

A vertical row of iine orifice holes 74 is provided along the outer surfceeoffthe. scouring line 631V It will be seen thatthe scouringgline 63. is much closer to the internal surfaceofthe'drum 52` than is the Naxiallrinsing line 61; andis thus able to deliver a moreviolent scouring spray.

Preferably, a shielding baffle 75 encircles the lowerend" of theaxial line 61 to preventexcessive ow ofiwater from being directed.downwardly intothe hollow shaft" 41V through the opening, in the/ center of the'disc`551.
2, vertical spray line 62 is` provided with a vertical row of orifice openings 76 Ywhich spray the entirevertical length' of the external surface of the drum 52.
Valve 64 is a three-way selector valve by whichfthe operator can direct liquid to bothv inner and outer sprays, or all to either line 65 or 66.
It'will be understood, that more than one vertical row' of spray holes 71, 74 and 76 may be provided, and that" these spray holes do not necessarily have to be in a perfect vertical row.
