1' Claim.

This invention relates to new and useful improvements in means for removing tank sediment and tank scale from oil tanks and the like.

A principal object of the present invention is to provide means for removing foreign sediment from oil contained tanks in an efficient and oil wasteless manner.

Other objects and advantages of the invention will become apparent to the reader of the following description.

In the drawings:

Figure 1 represents a side elevational view of the present invention attached to a tank, the tank being shown broken away in parts.

Figure 2 is a section on the line 22 of Figure 1.

Figure 3 is a sectional view taken substantially on the line 33 of Figure 2.

Figure 4 is a section on the line 4--4 of Figure 3.

Figure 5 is a perspective view of the follower spool.

Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 5 denotes an oil tank, while numeral 6 generally refers to the present invention.

In carrying out the present invention, a barrel I is removably secured as at 8 to the lower portion of the tank 5 at a point about an opening 9 formed in the lower portion of the tank.

The outer end of the barrel 1 is threadedly engaged as at III with the body II of a valve structure, preferably including a valve gate I2. The other side of the valve is connected to one end of a packing gland I3 which has a threaded end over which a rotatable cap I4 fits. The cap is threadedly engaged with the box I3 and has a spool-dike follower I5 therein which circumscribes an induction pipe I6, which pipe extends longitudinally through the packing box I3, valve body II, barrel I and into the tank 5 where it is provided with a pick up head I1.

Suitable packing material I8 is provided in the box I3, the box I3 having an internal flange I9 against which a stop Washer 20 for the packing material I8 abuts. A slide washer 2| is provided against the other end of the packing material and against this bears the follower I5.

It can be seen, that when it is desired to clean the sediment from the tank 5, the valve gate I2 is open, and the head I'I pushed from the right side of the valve element I2 in Figure 3, through the opening 9 and into the tank. Should any leakage occur, the same can be remedied by tightening the cap I4, which, of course, will push the follower I5 against the packing material I8 and compress the same against the eduction tube I6.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the claimed as new is:

A clean-out device for a liquid containing tank having a bottom side outlet, said device comprising a tube adapted to be fixed at one end to said tank to extend from said outlet, a gate valve on the other end of said tube having a gate movable into tube opening and closing popsitions and provided with a tube opening aperture aligned with the tube when said gate is in tube opening osition, a removable packing gland on said valve aligned with said tube, and a cleanout pipe extended through said gland and aperture and adapted to be extended into said tank through said outlet, said pipe being slidable in said gland to retract the same out of said aperture and thereby permit movement of said gate to tube closing position.
