PIPE CLEANING APPARATUS Filed'Sepb. 30, 1950 1 VE/V T085 ['rwz'n 5171002 Karl fiez'sezs Patented Nov. 15,, 1932 EBWIN SCHOENER AND KARL FREISEIS, BROOKLYN, NEW YORK PIPE CLEANING APPARATUS Application filed September 30, 1930. Serial No. 485,438.

This invention relates to improvements in cleamngdev ces for pipe condults particularly thecleaning of beer pipe lines, and it is the principal object of our invention to provide a device of this type in which the cleaning beads are collected in the conduit to form a compact body of a length proportionate to the length of the pipe conduit, and as such-- returned into the bead reservoir so that all loss of cleaning beads is efi'ectively avoided,

while the waste water is discharged In the known devices of this kind the cleaning beads are distributed singly in the pipe line and are prevented by the necessarily constant operation of the four-way cock to effect a cleaning under full pressure to return as a body into their reservoir resulting in a loss of beads and the undesirable presence of stray beads within the line.

It is the object of our invention to overcome this disadvantage and therefore another object of our invention is the provision of a plurality of damper-and throttle' lates within the pipe line to collect the bea s for their return in one body to the bead reservoir.

A further object of our invention is the provision of a bead-pipe line cleaning device in which the damper plates are provided with a plurality of openings allowing the passage of the cleaning fluid and 'dirt or residue while retaining the beads.

' A still further object of our invention is the provision of a bead-linecleaning device of' comparatively simple and therefore inexpensive construction, yet durable and highly efficient in operation.

These and other objects and advantages of our invention will become more fully known as the description thereof proceeds and will then be specifically defined in the 'ap-.

pended claim. 4 i

In the acompanying drawing forminga material part of this disclosure:

Figs. 3, 4, 5, and 6, are. sectional views on line 33 of Figure 2, illustrating the various positions of the four-Way cock. I

Fig. 7 is a sectional elevation of a modified form of a four-way valve and illustrating the arrangement of a sieve.

As' illustrated, the cleansing water passes through pipe 10, adapted'to be attached to a source ofwater into an injector 11 of standard construction. A reservoir 12 adapted to contain the cleaning beads is connected by means of a conduit 13 controlled by a valve 14 with the mixing chamber 15 into which the beads are drawn to be injected by the inj ector into the pipe 16 connected by the fourwaycock 17 with the

pipe lines

18, 18, leadmg to the conduit to be cleaned.

A pipe conduit 19 .conducts the beads back into the head 20 of reservoirl2, which is equipped with an annular inspection 0 ening covered by a glass plate 21 held in'p ace by means of

plates

22, 23, held together by headed bolts 24 and their nuts 25, while the waste water is removed through pipe 26 A cleaner nipple 27 controlled by, a valve 28 is provid: d near the bottom of"reservoir 1 2, and the injector can be regulated by means of a valve 29.

The valve body 30 of the four way cock is adapted to be operated by means-of a handle 31.

According to our invention a number of damper or throttle plates 32 in the body 30 of the valve and moving therewith are interposed in the pipeline at the four-way cock connection with the body thereof which at certain times as will be hereafter Indie fully described close one or the other of the pipes in order to allow a collection of the beads in the pipe line as a compact body for their return into the reservoir 12 as for instance indicated at 33 in Figure 1 within pipe 18.

In Figure 7, we have shown the customary form of our damper plate 32, provided with a plurality of" openings 34 for a purpose hereafter more fullyv to be described.

The device operates as follows:

returned after their passage through said pipe line through pipe 18. They arrive at the second damper plate 32' which is in a position closing conduit 18 so that the beads must collect therein as a compact body as indicated at 33 in Figure 1, while the water flows through openings 31 in the damper plate into conduit 19 leaving-through pipe 26 and hose attached thereto.

If now the four-way cock body 30, to which the dampers are connected is turned into the position indicated in Figure 4 in which the water upon closure of cock 14 rushing through the injector and pipe 16 will pass through damper plate 32 into pipe line 18 circulating the body of beads 33 through the bead pipe line into pipe 18, the damper 32 of which is closed to stop the beads while allowing the water to flow off through pipe 19. If now the four-way-cock is turned to assume the position illustrated in Figure 5,

the water will enter pipe 16 and through damper 32 into pipe 18 to drive the body of beads in said line into the beer pipe line to circulate therethrough and return the body of heads into line 18 the damper 32 of which being closed will stop the beads while the water can flow ofi through the openings in saidplate into pipe line 19.

If now the valve body 30 is turned by means of its handle 31 into the position shown in Figure 6, the water rushing through pipe 16 will drive the body of beads collected in pipe 18 to circulate again through the beer pipe line and then return through pipe 18', the damper 32 of which is open so that said body of beads can return into reservoir 12, while the water is drawn ofi at 26.

It will be clear that the damper plates 32, 32', can be steered by any suitable mechanical means or may be so connected to the valve body to assume their proper positions corresponding to the various turning movements of the valve body, and that upon closure of cock 14 while the beads are collected in reservoir 12 as aforedescribed a cleaning of the beer conduit with glean water can be etfected in alternate directions according to the various positions of the four-way cock.

If desired a receptacle 35 containing a cleaning chemical may be connected with the injector.

It willbe understood that we have described and shown the preferred form of our device only and that we may make such changes therein, and in the construction of the minor details thereof as come within the scopev of the appended claim without departure from the spirit of our invention and the principles involved.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent is:

In an apparatus of the classdescribed, a pipe line, a reservoir for the cleaning bea s,

an injector, a water supply for said injecto voir, and means for discharging the waste water and residue of the cleaning process.
