Abstract
Abstract A tank cleaning machine which comprises a nozzle manifold having one or more nozzles, that can be fed into and retracted from a tank while rotating or oscillating while cleaning fluid is supplied from a hose so that jet cleaning streams are directed to only those areas inside the tank that require cleaning. A very important feature of this device is to be able to clean very long horizontal or high vertical tanks and have the nozzles move along the tank greatly reducing the distance that the jet cleaning streams must travel after leaving the nozzles resulting in greater impact scrubbing action and reducing the breaking up of the stream to give very high efficiency. The travel feature of the nozzle manifold also permits the addition of a mechanical scrubber, or scraper with a trip arm to allow removal of sludge as the manifold is removed from the tank. Several variations of the manifold track can be made, one is telescoping it for easy removal so that the entire machine can be moved from one tank to another if desired. The unique hose reel features allow a compact design and permits automatic programming to the necessary areas only with independent automatic operation of the rotation and travel features.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
189 words
A Tank cleaning machine comprising a housing, a hose, a nozzle manifold having one or more nozzles, means of connecting the nozzle manifold to the hose to allow the nozzle manifold to rotate or oscillate without the hose rotating, means to feed the nozzle manifold into and out of a tank being cleaned, means to supply pressurized liquid to the hose end opposite the nozzle manifold, means to control from outside the tank the rate of travel of the nozzle manifold into and out of the tank being cleaned, means to operate the rotation or oscillation of the nozzle manifold from outside the tank with or without liquid flowing, means to vary the degree of the oscillating arc and the speed of this oscillation as well as the speed of rotation if full rotation is desired of the nozzle manifold from outside the tank with or without liquid flowing, means to determine the direction and location of flow of the cleaning liquid from the nozzle, and thus know the area of the tank being cleaned by simply observing the mechanism of the cleaning machine that is outside the tank.
Claim 2
Dependent Claim
189 words
A Tank cleaning machine comprising a housing, a hose, a nozzle manifold having one or more nozzles, means of connecting the nozzle manifold to the hose to allow the nozzle manifold to rotate or oscillate without the hose rotating, means to feed the nozzle manifold into and out of a tank being cleaned, means to supply pressurized liquid to the hose end opposite the nozzle manifold, means to control from outside the tank the rate of travel of the nozzle manifold into and out of the tank being cleaned, means to operate the rotation or oscillation of the nozzle manifold from outside the tank with or without liquid flowing, means to vary the degree of the oscillating arc and the speed of this oscillation as well as the speed of rotation if full rotation is desired of the nozzle manifold from outside the tank with or without liquid flowing, means to determine the direction and location of flow of the cleaning liquid from the nozzle, and thus know the area of the tank being cleaned by simply observing the mechanism of the cleaning machine that is outside the tank.
Claim 3
Dependent Claim
39 words
A tank cleaning machine of claim 1 including a track, means to mount the track inside a tank either permanently or means to easily remove the track and move to another tank with or without having the track telescopic.
Claim 4
Dependent Claim
90 words
A tank cleaning machine of claim 2 including a track bearing and a bearing housing at each end of track, means to attach and seal the entrance end bearing housing thru which the nozzle manifold and the hose enters the tank so the tank can be pressurized when the tank cleaning machine is not operating and when the hose is fully retracted from the tank, means to support nozzle manifold and hose with the track while cleaning, means to control from outside the tank the rotation of the nozzle manifold.
Claim 5
Dependent Claim
127 words
A tank cleaning machine of claim 3 including a hose reel, a stationary fluid supply pipe, means to attach the supply pipe to the housing, means for fluid to flow from the supply pipe connection thru the hose supply connection and thru the hose and out the opposite end of the hose and thru the nozzle manifold and out the nozzles while the hose is fully wound or being fed or wound back onto the reel, means to pull or feed the nozzle manifold end of the hose from the reel in a longitudinal manner so that the hose always leaves the reel tangentially and at the same location or spot, with respect to the housing as the reel turns and to rewind in the same manner.
Claim 6
Dependent Claim
70 words
A tank cleaning machine of claim 4 including a hollow stationary center shaft for the reel which connects to the supply pipe and with the opposite end of the center shaft sealed and with an outlet hole in the circumference, means for the stationary center shaft to support the reel from the housing, means for a fluid to flow from the outlet hole to the supply end of the hose.
Claim 7
Dependent Claim
69 words
A tank cleaning machine of claim 5 including a fluid supply chamber with bearings sealed and riding on the center shaft, means to attach the supply chamber to the reel so the reel and supply chamber will rotate and move axially with the reel, means to connect the supply chamber to the supply end of the hose so a fluid will flow from the supply chamber into the hose.
Claim 8
Dependent Claim
47 words
A tank cleaning machine of claim 6 including a radial pipe connection from the supply chamber to the supply end of the hose, spokes to support the reel, a hub attached to the supply chamber, means to attach the spokes to the hub and to the reel.
Claim 9
Dependent Claim
111 words
A tank cleaning machine of claim 7 comprising fixed guides attached to the housing, a spiral worm or screw type flights attached and wound around the drum part of the reel with a pitch to be not less than the hose diameter plus the thickness of the flights, means for the hose to be wound between the flights on the drum part of the reel, means for the fixed guides to engage the flights so that as the reel rotates it is forced to move axially a distance of the flight pitch for each revolution of the reel in the manner a screw when rotated feeds axially thru a fixed nut.
Claim 10
Dependent Claim
67 words
A tank cleaning machine of claim 8 comprising a drive wheel for winding, a gripping device and a feed cylinder or a cable winch with a one way clutch, limit switches and cam operators, a wind cylinder and pawl, means to feed off the hose from reel, means to wind the hose all automatically and with all controls and operating devices to be air or fluid operated.
Claim 11
Dependent Claim
56 words
A tank cleaning machine of claim 2 including automatic controls and power operated motors or cylinders, means with one start signal to automatically feed or pull the nozzle manifold into a tank and back out and to shut down at the end of one complete cycle or to continue to operate until again signaled all automatically.
Claim 12
Dependent Claim
56 words
A tank cleaning machine of claim 3 including automatic controls and power operated motors or cylinders, means with one start signal to automatically feed or pull the nozzle manifold into a tank and back out and to shut down at the end of one complete cycle or to continue to operate until again signaled all automatically.
Claim 13
Dependent Claim
