Description

Sept. 10, 1935. F. BURKETT ET AL DEVICE FOR CLEANING AND FLUSHING PIPES Filed Aug. 11, 1935 ENVENTORS Bur 65y! and Patented Sept. 10, 1935 UNITED STATES Z,tld,037
PATENT OFFICE DEVICE FOR CLEANING AND FLUSHING PIPES 20 Claims.
Our invention relates to devices for the cleaning and flushing of pipes and refers particularly to devices adapted for the use of chemical solutions for that purpose.
While our device is adapted for the cleansing of deposits from any pipes, where such deposits are affected by chemical solutions. it is particularly adapted for the cleansing of pipes through which beer has been passed.
In the dispensing of beer it is customary to force the beer from containers, such as kegs or barrels, through cooled pipes to the faucets. During this process the pipes become fouled materially affecting the beer and hence it is necessary to thoroughly remove the deposited materials and to flush the pipes until they are completely purified.
For this purpose the application of a chemical cleansing, or detergent, compound in the solution is required, followed by a complete removal of the chemical by a fresh water flushing.
In order that such treatment may be both effective and economical, it is essential that the first portion of the cleansing solution passed through the pipes be strongly impregnated with the chemical, thus causing a strong effect upon the fouling materials in order to cause their destruction and removal.
The device of our invention accomplishes these desirable results, as will be evident upon a consideration of the accompanying drawing, in which similar parts are designated by similar numerals.
Figure 1 is a side view of one form of our device, partly broken away for purposes of description.
Figure 2 is an enlarged vertical cross section of the device shown in Figure 1.
Figure 3 is a section through the line 3-3 of Figure 2.
Figure 4 is a broken vertical cross section of a modified form of our device.
The particular form of the device of our invention, illustrated in Figures 1, 2 and 3, consists of an outer casing having the annular side l and the bottom .I.| the latter having an outwardly extended pipe section 12, the inner and outer faces of which are threaded. The bottom II also carries the inwardly extended annular boss l3.
The side it] carries the two pipe sections I4 and 15, the outward faces of which are threaded.
A removable cover l6 for the casing has an annular'recess .I I for the reception of the receptacle side l'fl, an inwardly extended annular boss I8, the outer face of which is threaded; an inwardly extended annular boss H); and an outwardly ex- (Ol. 225-43) tended pipe section 20, the outer face of which is threaded. The cover I6 is attached to the casing by screwing down thereon, the threads of the boss 18 meshing with threads upon the inner face i I of the upper portion of the casing side l0. A
within the pipe section l2, the top of the supply 0 pipe being closed by the cap 24.
A perforated chemical container consisting of the tubular member 25 is maintained in upright position by the boss l3 of the casing bottom H and the boss i9 of the cover it, the perforations being preferably in the upper portion thereof.
The pipe section l2 of the casing bottom I l carries the valve 26, which is connected to the pipe 21, which is connected to the pipe 28, carrying the valve 29. The valve 29 is connected to the pipe 36 which is connected to the coupling 31. The coupling 3| is connected to the pipe section l5 of the casing side ill by means of the check valve 32 and to the pipes to be cleaned and flushed by means of the pipe 33. 21 is connected to a supply of fresh water by means of the pipe 34.
A cap 35 closes the pipe section M of the casing side l0, and a strap 36 around the casing is adapted to retain the device upon a desirable support.
The operation of the device is as follows:
The cover 16, or the cap 2!, is removed and the necessary chemical 5B in solid form is introduced into the chemical container and the cover, or the cap, replaced. Valve 26 is opened and valve 29 is closed. Fresh water is then allowed to enter through the pipe 34. This water passes upwardly through the Valve 26, through the perforations in the water supply pipe 23 into the chemical container, where it dissolves the chemical, passes outwardly through the perforations in the chemical container wall into the chamber 31 and thence through the valve 32, the coupling 3| and the pipe 33 into and through the pipes to be cleaned and flushed, the flow of water being continued until such pipes are thoroughly cleaned.
It is evident that when all of the chemical has been dissolved and the solution passed through the system, clear water will pass through the device and will flush all of the chemical solution from the pipes to be cleaned.
If, however, it is desired to otherwise flush the pipes, the valve 26 is closed and the valve 29 is The pipe 25 opened. The clear water then passes through the system 21, 28, 29, 30, 3|, and 33, the check valve 32 preventing it from entering the casing.
The modification of our device shown in Figure 4 consists of a casing having the annular side 38 and the bottom 39, the latter having the extended pipe section 40, the inner and outer faces of which are threaded. A perforated water supply pipe 4| is threaded into the pipe section 49.
A chemical container consists of the annular side 42 abutting upon the inner face of the casing side 38, the converging shoulder 43 and the upwardly extended tubular portion 4 3, said tubular member 44 being perforated. The remainder of the device is similar to that shown in Figures 1, 2 and 3 and described therewith.
In the operation of this modified form of our device, the clear water enters the water supply pipe 4!, passes through the perforations therein, enters the chemical container, dissolves the chemical, passes through the perforations in the tubular member 44 into the chamber and thence outwardly through the system into the pip-es to be cleaned.
It will be noted that in both of these devices, the first portion of clear water fed into the device passes through a larger quantity of chemical than does that which follows and that, therefore, the first quantity of liquid passing through the pipes to be cleaned contains a larger quantity of chemical than does the following solution, and this is a most valuable feature of the device, as it is desirable to treat the deposited impurities with as strong a solution as possible in order to dislodge, dissolve and remove them. The operation can thus be performed much more economically and rapidly than if a weaker solution is applied to these deposits.
It will thus be seen that our invention presents a device which will efficiently remove deposits from beer pipes and other pipes, followed by a thorough flushing to remove the chemicals employed in the process.
We do not limit ourselves to the particular size, shape, number or arrangement of parts as shown and described, as these are given simply as a means for clearly describing the device of our invention.
