APPARATUS FOR FIL'IERNG AND BOTILING FLUIQDS UNDER PRESSURE.

Application led January 20, 1928.

The invention relates to apparatus for bottling fluids under pressure and especially effervescent fluids, which are to be filtered at the same time they are bottled.

The present invention is an improvement on my invention covered in the copending application Serial No. 236,309 filed Nov. 28, 1927.

The object of the present invention is to provide a bottling and filtering device the different compartments whereof are all formed by one integral container.

Other objects of the invention not specifically mentioned may he easily ascertained and understood fromv the followingdoser-ip tion in. connection with the accompanying drawings forming a part thereof. It is however to be noted, that the invention is not to be limited or restricted to the exact construction or formation shown in the drawings and described in the specification, but that the invention is only to be limited by the scope of the claims appended hereto.

In the drawings:

Fig. 1 is an elevation of the apparatus according to the present invention, and

Fig. 2 is a vertical section through said apparatus.

The body of the device consists of a con tainer 5 preferably made from sheet copper. At the top said container is provided with a flange 6. This flange is created by bending the metal, of which the container' is made, outwardly at right angles to the walls of said container, and then bending the metal forming the flange back upon itself, so that the fiange consists of two layers of nieta.. In order to reinforce the flange still more a steel ring 7 may be clamped in between the two layers of metal mentioned above.

To close the container 5 a lid 8 is pro-- vided. This lid has a flange 9, whioh is made in the sameway as the 6. @n

the latter a plurality of clamps 10 arc hingedly fastened, which can be swung` into clamping position as shown in the drawings to engage the flange of the lid and force the same down onto the container. A rubber ring 11 or any other suitable packingring may be arranged between the two flanges, so that the lid will close the container hermetically, when the clamps are forced down onto the flange 9 of the lid.

rihe container may be provided with a plurality of legs 12. In a distance of about one third of the height of the container from Serial No. 248,077.

the bottom a supporting ring 1B or the like is -fastened to the inner face of the container, and a comparatively strong` false bottom plate 11i rests on said ring. A spacer ring 15 is placed on top of said plate and a coarse sieve plate 1G is supported by said spacer ring. On top of this sieve plate a line sieve plate 17 is located, and this plate carries a layer of filter material 18, for infx stance cotton. Another line sieve plate 19 rests on said filter material. and al second coarse sieve plate 2O is arranged on top of the last named plate. A second spacer ring 21 rests on top of the plate 2O and abuts with ils upper rim the lid 8. l/Vhen the filter material is arranged in its place it is loosely packed, so that the upper rim of the ring 21. extends somewhat beyond the container. lhen then the lid is forced down, the filter material is compressed, and the plate 14C is forced upon the supporting ring 13. ln order to make the connection between the plate and the ring leak-proof a packing ring 22 or the like may be arranged be tween the two members. A short inlet pipe 23 provided with a valve 24 leads into the interior of the container adjacent the upper rim thereof, and a baffle plate 25 is fastened to the inner face of the container in such a manner, that any liquid entering` the container through the inlet pipe will be deflected against the wall of the container and will flow down on said wall instead of falling freely onto the filter. in this manner objectionable foaming` of the liquid to be treated is obviated. The spacer ring 21 has a cut-out portion, as indicated in llig. 2 to permit of the mounting of the baffle plate 25 and the entrance of the fluid to be treated.

From the space between the plate 14 and the sieve plate 16 a pipe 26 leads to the space below the plate 14, and in this pipe a valve 27 is arranged. A slot or opening is provided in the spacer ring` 15 to permit the pipe to communicate with the interior of the container. Adjacent the place where the pipe 26 enters the space below the plate 111, a second baffle plate 28 is fastened to the inner face of the wall of the container for the same purpose as described above with reference to the baffle plate 25.

lnto the wall of the container two fluid gauges 29 and 3() are set, the one above the level of the upper coarse sieve plate 20, when the lid is pressed down onto the container, and the other one below the level of the ion `plate I4. Amanometer 8l may be arranged on the lid 8. y

A tank 32 is fastened in anyfconvenient manner to the outside ot the cont-ainer, and adjacent said tank an air pump 33 is also mounted on said container. A tube 34 leads from the pump to the` tank, so that comf pressed air may be stored in said tank. A pipe 35 leads form the tank into the upper part of the container and a stop cock 8bV regulates the flow of compressed air through said nipple. Adjacent the bottom 'of the container a cock 4l is arranged for draining the fluid from the lower portion of the container.

valve 42 is provided.

The device is operated ,in the following manor: The liquid to be treated is brought into the upper portion of the container in any convenient manner. Vhen for instance the liquid to be treated is in a can, the lid 8 may be removed and the liquid may then be poured into the container, whereupon the lid is fastened tightly onto the container by means of the clamps l0. Or, if the liquid to be treated should be contained in a demijohn or the like a tube extending through the cork of the demijohn may be immerged into the fluid to be treated and the other end of p the tube .may then be attached to the inlet pipe 23. Another tube may be fastened to the nipple 39 and may lead through thel cork of the demijohn. The valve 24 and the cock A are opened, after the lid 8 has been seated In order to let the superfluous air out of the lower portion of the container av plates and the filter material. The valve 27 is opened and the filtered liquid will flow into the lower portion oi' the container. If the liquid being treated is an effervescent liquid, such as ginger aleor the like,`vit is vnecessary to keep the liquid continuously under pressure, and for that purpose the cock 38 in pipe 87 is opened permitting coinpressed air to flow into the part of the container underneath the false bottom plate 14. By opening the cock or spigot 4l the filtered liquid may be drawn from the con*- tainer, while the liquid is under pressure. What I claim as newis: Y l. In a device of the class described a container, a lid therefor, means forY seating said lid tightly and firmly onto the container,

a false bottom in said container arranged at a distance from the real bottom thereof, a filter arranged in said container ata distance above saidl false bottom, an air compressing derice communicating with the top portion of the container, an inlet'pipe communicating with said portion, a pipe connecting the space between the filter and the false bottom .with the space beneath said false" plate on top of said filter material, va secon-dy spacer ring seated on said u'ppersieve plate, the lid being adapted to engage the upper rim of said ring and to force it downwardly, when the lid is being clamped tightly onto the container, an'inlet communicating with the top portion oi the container, an air compressing means communicating with the same portion, a pipe connecting the space between the filter and the false bottom with the space underneath saidv false bottom, means for conducting compressed air into said last named space, and an outlet on the container adjacent the bottom thereof.

In witness Awhereof I affix my signature.V
